Toyota RAV4 low tire pressure warning light causes, how to reset

Toyota RAV4 is equipped with Tire Pressure Monitoring System (TPMS) for the purpose of warning the driver when one or more of the tires are significantly under-inflated, creating a potentially unsafe driving condition. In this article we discuss the reasons for the amber colored TPMS warning light in RAV4, and how you can reset it.

The TPMS warning light illuminates in Toyota RAV4 when air pressure is low in one or more of the tires, battery has depleted in a pressure sensor, TPMS receiver module has malfunctioned, or a pressure sensor has been damaged.


Low tire pressure

When the amber colored TPMS warning light turns on in your RAV4, stop your vehicle when it is safe to do so and check tire pressure on all the wheels, including the spare wheel (if your vehicle has one). Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure.

Reinflate the tires

Reinflate all the tires of your RAV4 to the manufacturer specified air pressure, which is mentioned on the vehicle placard or tire inflation pressure label usually located on the B-pillar or the edge of the driver door. If you can’t find the label, check the size of your tire which is mentioned on the sidewall of the tire, and match it to the tire pressure information shown below. These are official cold tire pressure values for 5th generation RAV4 from Toyota.

  • 225/65R17 102H: 35 – 36 psi
  • 225/60R18 100H: 33 psi
  • 235/55R19 101V: 33 – 35 psi
  • T165/80R17 104M (spare wheel): 60 psi
  • T165/90D18 107M (spare wheel): 60 psi
See the sidewall of any tire on your RAV4 to find the tire size information.

Resetting the TPMS warning light

After you have inflated all the tires to the correct air pressure, the TPMS warning light should turn off automatically after driving for a few miles. Toyota RAV4 uses the direct method for monitoring tire pressure, which means a pressure sensor actively records the internal pressure of the tire on each wheel. If the warning light doesn’t turn off you should perform a reset procedure from the instrument cluster settings.

The tire pressure warning system must be initialized in the following circumstances:

  • When rotating front and rear tires which have different tire inflation pressures.
  • When changing the tire size.
  • When the tire inflation pressure is changed such as when changing traveling speed or load weight.
  • When changing between two registered wheel sets.
  • After registering the ID codes.

When the tire pressure warning system is initialized, the current tire inflation pressure is set as the benchmark pressure.

Even if the vehicle is not driven at approximately 25 mph (40 km/h) or more, initialization can be completed by driving for a long time. However, if initialization does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 20 minutes and then drive the vehicle again.

WARNING! Do not initialize tire inflation pressure without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal.

If the low tire pressure light does not turn off automatically after reinflating the tires in your RAV4, increase the tire pressure by 5 psi on top of the factory recommended value, and drive your vehicle for at least 10 miles (16 km). After the TPMS warning light turns off, and the vehicle has been parked for a few hours, reduce the tire pressure to the factory recommended value.

Chilly weather can turn on low tire pressure light in RAV4

Cold weather is one of the most common cause for low tire pressure warning light in Toyota RAV4. When analyzing WheelsJoint’s statistical data, it has been observed that there is sharp rise in the number of searches for TPMS warning light causes at the start of every winter season, about three times higher as compared to mid summer season.

The air, like most other substances, expands when heated and contracts when cooled. So when the weather gets colder, the tire pressure decreases, which could trigger TPMS warning light in RAV4. The tire pressure will vary with temperature by about 1 psi (7 kPa) for every 12°F (6.5°C).

Tire pressure vs temperature: This chart shows how tire pressure of 35 psi at temperature of 35°C (95°F) decreases by roughly 1.6 psi with every 10°C (18°F) drop in temperature.

Inflate tires when cold

Tire pressure in RAV4 should always be set based on cold inflation tire pressure. This is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1.6 km) after a three-hour period.

Do not adjust tire pressure when hot

The tires on your RAV4 can get around 50 degrees hotter than the outside temperature when you’re driving, which increases the tire pressure by about 4 psi – this is normal and there should be no adjustment for this increased pressure.

Does altitude affect tire pressure?

Yes, altitude can change tire pressure values, but it is negligible and not a cause for concern. If you drive your RAV4 from sea level to Mount Evans Scenic Byway in Colorado which is the highest paved road in North America at the altitude of 14,130 feet (4,307 m), the tire pressure should theoretically increase by approximately 6 psi. But, the decrease in ambient temperature at higher elevation contracts the air in tires and compensates for any altitude pressure changes.


Is it safe to drive RAV4 with low tire pressure?

The driving characteristics of RAV4 change even if the air pressure is 5 psi less than manufacturer’s recommended value: the braking distance can be longer, cornering worse, and at particularly high speeds there is even a risk that the tire will burst. Low tire pressure also increases tire wear, and the higher rolling resistance of the tire means higher fuel consumption. So it is recommended to reinflate the tires to the correct pressure as soon as possible.

Dead battery in a tire pressure sensor

Each tire pressure sensor in RAV4 is powered by a built-in lithium-ion battery. When the battery is depleted, the sensor stops transmitting tire pressure information to the receiver module. When this happens, the TPMS warning light will flash every time the engine is started, and will remain illuminated until you turn off the vehicle.

How long do the pressure sensor batteries last?

The tire pressure sensor batteries usually last anywhere from 5 to 10 years in RAV4. When the battery is depleted, you must replace the sensor itself, as the battery is sealed into the sensor unit and is non-replaceable.

Identifying a faulty pressure sensor

The most reliable method for detecting a faulty tire pressure sensor or a sensor with dead battery is by testing each sensor with a scan tool. For example, MaxiTPMS TS408 is commonly used for diagnosing and programming tire pressure sensors. A sensor that is not detectable by the scanner is most likely defective and should be replaced with a new one.

Scan each wheel with a scan tool like MaxiTPMS TS408 and see which one does not respond.

If you don’t want to spend over a hundred bucks on a scanner, then head over to any reputable tire shop and perform a TPMS diagnostic scan of your RAV4. Some shops like Discount Tire and Pep Boys offer free of charge TPMS diagnostic services.

Installed new tires?

If a pressure sensor stopped responding after you installed new tires on your RAV4, it is possible the sensor got damaged during tire installation. These sensors are quite sensitive, and can be easily damaged if utmost care is not taken while changing tires.

Toyota RAV4 TPMS user guide

Your vehicle is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire inflation pressure before serious problems arise.

If the tire pressure drops below a predetermined level, the driver is warned by a screen display and by a warning light.

The tire pressure detected by the tire pressure warning system can be displayed on the multi-information display.

Tire inflation pressure

It may take a few minutes to display the tire inflation pressure after the engine switch is turned to ON. It may also take a few minutes to display the tire inflation pressure after inflation pressure has been adjusted. Tire inflation pressure changes with temperature. The displayed values may also be different from the values measured using a tire pressure gauge.

TPMS reset guidelines

  • Initialization is performed while driving at a vehicle speed of approximately 25 mph (40 km/h) or more.
  • Make sure to carry out initialization after adjusting the tire inflation pressure. Also, make sure the tires are cold before carrying out initialization or tire inflation pressure adjustment.
  • The tire pressure warning system can be initialized by yourself, but depending on the driving conditions and driving environment, initialization may take some time to complete.
  • If you have accidentally turned the engine switch to OFF during initialization, it is not necessary to restart the initialization again as initialization will restart automatically when the engine switch has been turned to ON for the next time.
  • If you accidentally perform the initialization when initialization is not necessary, adjust the tire inflation pressure to the specified level when the tires are cold, and conduct initialization again.
  • While the position of each tire is being determined and the inflation pressures are not being displayed on the multi-information display, if the inflation pressure of a tire drops, the tire pressure warning light will come on.

When initialization of the tire pressure warning system has failed

Initialization can be completed in a few minutes. However, in the following cases, the settings have not been recorded and the system will not operate properly. If repeated attempts to record tire inflation pressure settings are unsuccessful, have the vehicle inspected by your Toyota dealer.

  • When operating the tire pressure warning reset switch, the tire pressure warning light does not blink 3 times.
  • After driving for a certain period of time since the initialization has been completed, the warning light comes on after blinking for 1 minute.

If the tire pressure warning system is not initialized properly

In the following situations, initialization may take longer than usual to be completed or may not be possible. Normally, initialization completes within approximately 30 minutes.

  • Vehicle is not driven at approximately 25 mph (40 km/h) or more.
  • Vehicle is driven on unpaved roads.
  • Vehicle is driven near other vehicles and system cannot recognize tire pressure warning valve and transmitters of your vehicle over those of other vehicles.
  • If the vehicle is driven in heavy traffic or another situation where other vehicles are driven close by, it may take time for the system to recognize the tire pressure warning valve and transmitters of your vehicle over those of other vehicles.

If initialization does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 20 minutes and then drive the vehicle again.

  • If the vehicle is reversed during initialization, the data up to that point is reset, so perform the initialization procedure again from the beginning.

In the following situations, initialization will not be started or was not completed properly and the system will not operate properly. Perform the initialization procedure again.

  • If, when attempting to start initialization, the tire pressure warning light does not blink 3 times.
  • If, when the vehicle has been driven for about 20 minutes after performing initialization, the tire pressure warning light blinks for approximately 1 minute and then illuminates.

If the inflation pressure of each tire is still not displayed, have the vehicle inspected by your Toyota dealer.

Situations in which the tire pressure warning system may not operate properly

In the following cases, the tire pressure warning system may not operate properly.

  • If non-genuine Toyota wheels are used.
  • A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
  • A tire has been replaced with a tire that is not of the specified size.
  • Tire chains, etc. are equipped.
  • An auxiliary-supported run-flat tire is equipped.
  • If a window tint that affects the radio wave signals is installed.
  • If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel housings.
  • If the tire inflation pressure is extremely higher than the specified level.
  • If wheel without tire pressure warning valves and transmitters are used.
  • If the ID code on the tire pressure warning valves and transmitters is not registered in the tire pressure warning computer.

Performance may be affected in the following situations.

  • Near a TV tower, electric power plant, gas station, radio station, large display, airport or other facility that generates strong radio waves or electrical noise.
  • When carrying a portable radio, cellular phone, cordless phone or other wireless communication device.

If tire position information is not correctly displayed due to the radio wave conditions, the display may be corrected by driving and changing the radio wave conditions

  • When the vehicle is parked, the time taken for the warning to start or go off could be extended.
  • When tire inflation pressure declines rapidly for example when a tire has burst, the warning may not function.

Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accordance with the conditions under which it was initialized. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized.

Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed. When new tire pressure warning valves and transmitters are installed, new ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized.

When replacing the tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work properly. After driving for about 20 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunction.

Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps

  • When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your Toyota dealer as the tire pressure warning valves and transmitters may be damaged if not handled correctly.
  • Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire pressure warning valves and the tire pressure warning valves could be bound.
  • When replacing tire valve caps, do not use tire valve caps other than those specified. The cap may become stuck.

Registering ID codes

Every tire pressure warning valve and transmitter has a unique ID code. When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID code. When registering the ID codes, perform the following procedure.

  1. Park the vehicle in a safe place, wait for approximately 20 minutes, and then start the engine.
  2. Select the settings tab in the instrument cluster display using steering wheel controls.
  3. Select Vehicle Settings and then press and hold the OK button.
  4. Select TPWS.
  5. Select Change Wheel. Then press and hold the OK button until the tire pressure warning light starts slowly blinking 3 times.
  6. The change wheel set mode is activated and registration is started. Then a message will be displayed on the multi-information display.
  7. When registration is being performed, the tire pressure warning light will blink for approximately 1 minute then illuminate and “- – -” will be displayed for the inflation pressure of each tire on the multi-information display.
  8. Drive straight (with occasional left and right turns) at approximately 25mph (40 km/h) or more for approximately 10 to 30 minutes.
  9. Initialize the tire pressure warning system.

When registration is completed, the tire pressure warning light will go off and the inflation pressure of each tire will be displayed on the multiinformation display.

Even if the vehicle is not driven at approximately 25 mph (40 km/h) or more, registration can be completed by driving for a long time. However, if registration does not complete after driving for 1 hour or more, perform the procedure again from the beginning.

When registering ID codes

  • ID code registration is performed while driving at a vehicle speed of approximately 25 mph (40 km/h) or more.
  • Before performing ID code registration, make sure that no wheels with tire pressure warning valve and transmitters installed are near the vehicle.
  • Make sure to initialize the tire pressure warning system after registering the ID codes. If the system is initialized before registering the ID codes, the initialized values will be invalid.
  • ID codes can be registered by yourself, but depending on the driving conditions and driving environment, registration may take some time to complete.
  • As the tires will be warm when registration is completed, make sure to allow the tires to cool before performing initialization.

Canceling ID code registration

  • To cancel ID code registration after it has been started, turn the engine switch to OFF before driving the vehicle. If the vehicle is driven after ID code registration is started, to cancel registration, perform the ID code registration start procedure again and turn the engine switch to OFF before driving.
  • If ID code registration has been canceled, the tire pressure warning light will blink for approximately 1 minute when the engine switch is turned to ON and then illuminate. The tire pressure warning system will be operational when the tire pressure warning light turns off.
  • If the warning light does not turn off even after several minutes have elapsed, ID code registration may not have been canceled correctly. To cancel registration, perform the ID code registration start procedure again and then turn the engine switch to OFF before driving.

If ID codes are not registered properly

In the following situations, ID code registration may take longer than usual to be completed or may not be possible. Normally, registration completes within approximately 30 minutes. If ID code registration is not complete after driving for approximately 30 minutes, continue driving for a while.

  • Vehicle is not parked for approximately 20 minutes or more before driving.
  • Vehicle is not driven at approximately 25 mph (40 km/h) or more.
  • Vehicle is driven on unpaved roads.
  • Vehicle is driven near other vehicles and system cannot recognize tire pressure warning valve and transmitters of your vehicle over those of other vehicles.
  • Wheel with tire pressure warning valve and transmitter installed is inside or near the vehicle

If registration does not complete after driving for 1 hour or more, perform the ID code registration procedure again from the beginning.

If the vehicle is reversed during registration, the data up to that point is reset, so perform the registration procedure again from the beginning.

In the following situations, ID code registration will not be started or was not completed properly and the system will not operate properly. Perform the ID code registration procedure again.

  • If, when attempting to start ID code registration, the tire pressure warning light does not blink slowly 3 times.
  • If, when the vehicle has been driven for about 20 minutes after performing ID code registration, the tire pressure warning light blinks for approximately 1 minute and then illuminates.

If the ID codes cannot be registered even when performing the above procedure, contact your Toyota dealer.

Reset the entire system

If the low tire pressure warning light won’t turn off due to a glitch in the tire pressure monitoring system, it may be possible to reset the TPMS system by resetting all on-board computers in your RAV4. This method should only be considered as a last resort, when all else fails.

Disconnect both negative and positive terminals of the battery.

You can reboot all the on-board computers by disconnecting the main 12 volt battery for a few minutes. Remove the cable from the negative terminal of the battery first, then from the positive terminal. With the battery disconnected, press the horn button a few times and turn on the headlights to drain out all the residual electricity from the system. After about 15 minutes, reconnect the battery in reverse order: positive cable first, then negative cable.

Tire pressure keeps getting low

If the TPMS warning light turns on frequently in your RAV4, and the tire pressure is also decreasing after you have reinflated the tires, there may be an air leak. One or more of the tires may have been punctured by an external object, or the air may be leaking from a defective value stem.

A punctured tire can be plugged with a tire repair kit if the puncture is not near the sidewall.

Can I disable the TPMS system in RAV4?

No, the TPMS system is federally mandated, and cannot be disabled in Toyota RAV4. All vehicles must have a working tire pressure monitoring system to be legally compliant.

Use OBD2 scanner for diagnosis

Since Toyota RAV4 is equipped with on-board diagnostics (OBD), a fault diagnosis can provide initial indications of where the malfunction is located. But when it comes to TPMS, a basic code reader will not suffice. You will need an advanced scanner to monitor TPMS data or read TPMS codes.

BlueDriver is a Bluetooth based diagnostic device which you can connect to the OBDII port in your vehicle and use your mobile phone for diagnosis. You will need to download the “BlueDriver OBD2 Scan Tool” app from the App Store on your iPhone, or from Google Play Store if you have an Android phone.

BlueDriver is a commonly used scanner by DIYers that can read TPMS codes for most vehicles and isn’t too expensive – costs about a hundred bucks. You can also clear the TPMS fault codes with this device which will turn off the warning light, but the light may come back on if the on-board diagnostic system detects a fault again.
