The remote start feature in Jeep Grand Cherokee has many benefits. You can start your vehicle in advance when the weather is too hot or cold outside. The system turns on the air conditioning or heating, making inside cabin temperature more tolerable when you get to your vehicle.


Remote start procedure for Grand Cherokee

You can remotely start your Jeep Grand Cherokee by following these simple steps:

  1. Press the REMOTE START button on the key fob twice within five seconds.
  2. The vehicle doors will lock, the parking lights will flash, and the horn will chirp twice. Then the engine starts.
  3. Once started remotely, the engine will run for 15 minutes and then shut down automatically.

The vehicle remains secured when you have remotely started the engine. A valid key must be inside the vehicle to be able to drive. For security, power window and power sunroof operation (if equipped) is disabled when the vehicle is in the Remote Start mode. The parking lights will turn on and remain on during remote start mode.

The remote start procedure must be performed within approximately 328 feet or 100 meters distance from your Grand Cherokee, otherwise the engine may not start. The range may be reduced due to weak battery in the key fob or external signal interference.

Remotely stop Grand Cherokee’s engine

Press the REMOTE START button once on the key fob to remotely stop the engine of your Jeep Grand Cherokee. The engine turns off and the doors remain locked. For this to work, the remote must be in the range of the smart entry system. If the remote is out of the range, the engine will not stop until 15 minutes duration has expired.

Note: To avoid unintentional shutdowns, the system will disable for two seconds after receiving a valid Remote Start request.

Driving after remote start

To start driving your Jeep Grand Cherokee when the engine is running after remote start, either push and release the unlock button on the key fob to unlock the doors, or unlock the vehicle using Keyless Enter ‘n Go™ — Passive Entry via the door handles, and disarm the Vehicle Security system (if equipped). Then, prior to the end of the 15 minute cycle, push and release the START/STOP ignition button.


Note: For vehicles equipped with the Keyless Enter ‘n Go™ — Passive Entry feature, the message “Remote Start Active — Push Start Button” will show in the instrument cluster display until you push the START/STOP ignition button.

Extending engine running time

When you remotely start the engine of your Jeep Grand Cherokee, it will run for 15 minutes and then shut off automatically. You can perform another remote start procedure by pressing the REMOTE START button twice within five seconds on the key fob, which will run the engine for another 15 minutes.

Maximum two remote starts

A maximum of two remote starts are allowed between ignition cycles on Grand Cherokee. The vehicle must be started normally before the remote start procedure can be used again.

Front and rear defrost

If the outside ambient temperature is 40°F (4.5°C) or below, the remote start system in Grand Cherokee will automatically activate front and rear defrost for 15 minutes or less. The time is dependent on the ambient temperature. Once the timer expires, the system will automatically adjust the settings depending on ambient conditions.

Heated and ventilated seats

When remote start is activated in Jeep Grand Cherokee, the heated steering wheel and driver heated seat feature will turn on if selected in the comfort menu screen within Uconnect Settings. In warm weather, the driver vented seat feature will automatically turn on when the Remote Start is activated, if programmed in the comfort menu screen. The vehicle will adjust the climate control settings depending on the outside ambient temperature.

Enable or disable heated and ventilated seats

If equipped and turned on, this feature will turn on the heated seats in your Grand Cherokee when using remote start on cold days.

  1. Go to Apps in the center infotainment system screen.
  2. Scroll down and select Vehicle.
  3. Select Settings tab.
  4. Scroll down and select Seats & Comfort.
  5. To enable the feature, select Remote Start or All Starts option next to Auto-On Heated/Ventilated Seat & Steering Wheel.
  6. To disable the feature, select Off option.

This setting will activate the vehicle’s comfort system and heated seats (if equipped) or heated steering wheel (if equipped) when the vehicle is remote started or ignition is started. The “Off” setting will not activate the comfort systems. The “Remote Start” setting will only activate the comfort systems when using remote start feature. The “All Start” setting will activate the comfort systems whenever the vehicle is started.

Climate Control

Automatic Temperature Control (ATC)

The climate controls will automatically adjust to the optimal temperature and mode settings depending on the outside ambient temperature. This will occur until the ignition is placed in the ON/RUN position where the climate controls will resume their previous settings.


These features will stay on through the duration of Remote Start until the ignition is placed in the ON/RUN position. The climate control setting will change, and exit automatic operation, if manually adjusted by the driver while the vehicle is in Remote Start mode. This includes the OFF button on the climate controls, which will turn the system off.

Windshield de-icer

When remote start is active and the outside ambient temperature is less than 33°F (0.6°C), the Windshield Wiper De-Icer will activate in Grand Cherokee. Exiting remote start will resume its previous operation. If the Windshield Wiper De-Icer was active, the timer and operation will continue.

Safety precautions

These are warnings against actions which may cause injury to people/vehicle if the warning is ignored.

  • Never start the engine of your Grand Cherokee in an enclosed area (such as a garage or indoor parking lot) where exhaust gases may accumulate and create a hazardous environment with potential for Carbon Monoxide (CO) poisoning. Breathing CO gas can cause unconsciousness and even kill you.
  • Do not start the engine if a child or pet are present in or near the vehicle.
  • Always turn off vehicle systems such as the windshield wipers, headlights and radio before leaving the vehicle. If left on, such systems may be damaged or vehicle battery depleted by remote engine start in extreme cold weather.
  • Do not use remote start if the vehicle is low on fuel. The vehicle may run out of fuel.

Engine idling law

There are laws against car idling with no passenger or driver inside in many states to protect the environment. It does not mean its completely illegal to use remote start, some states have time limit on how long you can keep the engine running. So check with your local state laws before using the remote start feature on your Jeep Grand Cherokee.
