Enable or Disable Drowsy Driver Alert in Jeep Grand Cherokee

The Jeep Grand Cherokee is equipped with various safety features to enhance the driving experience and ensure the well-being of both the driver and passengers. One such feature is the Drowsy Driver Detection (DDD) system, which monitors the driver’s behavior and provides warnings if signs of drowsiness are detected. If you own a Jeep Grand Cherokee and want to know how to enable or disable the Drowsy Driver Alert, follow the steps outlined below.

How Drowsy Driver Detection (DDD) system works

Drowsy Driver Detection is a safety feature implemented in vehicles, including the Jeep Grand Cherokee, to help prevent accidents caused by driver fatigue or drowsiness. The system continuously monitors the driver’s behavior and provides warnings or alerts if signs of drowsiness are detected, encouraging the driver to take a break and rest.

The Drowsy Driver Detection system operates by collecting data from various sources within the vehicle, such as the steering patterns, button and switch activity, and information from front-facing cameras. This data is then analyzed to assess the driver’s level of fatigue and determine if intervention is necessary.

The system utilizes two main operating logics:

Driving Style Logic

This logic focuses on the driver’s driving behavior and observes the road. It detects any instances of the vehicle crossing lane markings or deviating from the intended path. By analyzing these patterns, the system can evaluate the driver’s ability to continue driving without compromising safety.

Time-Based Logic

This logic considers the duration of time the driver spends behind the wheel at speeds between 40 mph (60 km/h) and 100 mph (160 km/h). It monitors the length of time without breaks and assesses the potential impact of fatigue on the driver’s performance.

When the Drowsy Driver Detection system determines that the driver’s behavior indicates fatigue or drowsiness, it activates a warning. The warning is typically displayed on the instrument cluster display within the driver’s view and is accompanied by an audible signal.

The driver is then prompted to take immediate action by pulling over to a safe location and taking a break. The warning serves as a reminder that driving while fatigued can be extremely dangerous and may increase the risk of accidents.

It’s important to note that the Drowsy Driver Detection system is designed as an aid to promote driver safety and alertness. However, it does not relieve the driver of their responsibility to remain attentive and well-rested while operating the vehicle. It is always recommended to prioritize getting adequate rest before driving and to proactively take breaks during long journeys to prevent fatigue.

The implementation of Drowsy Driver Detection in vehicles like the Jeep Grand Cherokee aims to enhance road safety by raising awareness about the risks associated with drowsy driving and encouraging drivers to prioritize their well-being on the road.

How to enable or disable DDD

Access the Vehicle Settings

Start by accessing the center screen display of your Jeep Grand Cherokee. Look for the “Vehicle” option on the bottom category bar and tap on it. This will open a new window with additional settings.

Navigate to Safety & Driving Assistance

In the top right corner of the screen, you will find a “Settings” option. Tap on it to open the settings menu. From the left menu, select “Safety & Driving Assistance.” This section houses various safety-related features.

Locate Drowsy Driver Alert

Scroll down the list of options until you find the “Drowsy Driver Alert” setting. This setting is responsible for monitoring your driving habits and providing warnings if signs of drowsiness are detected.

Enable or Disable the Drowsy Driver Alert

Once you locate the Drowsy Driver Detection option, you will see two available choices: “On” and “Off.” By default, it may be set to “On.” To enable the Drowsy Driver Alert, simply leave it as it is. If you wish to disable the alert, tap on the radio button to turn it off.

How to dismiss the warning message

If the system determines that the driver is unable to maintain proper lane position within the specified speed range, a warning will be displayed on the instrument cluster display, accompanied by an audible signal. When the warning appears, the driver has the option to acknowledge it by pressing the “OK” button on the left side of the steering wheel. If the driver does not respond within 60 seconds, the warning will disappear.

DDD system malfunction

In the event of a failure in the Drowsy Driver Detection system, a dedicated message will be displayed on the instrument cluster display, alerting the driver to the malfunction.


By following these steps, you can easily enable or disable the Drowsy Driver Alert system in your Jeep Grand Cherokee. Remember, this feature is a valuable aid to help you stay alert on the road, but it should never replace your own responsibility to drive safely and ensure you are well-rested before embarking on a journey.
