For enhanced safety, the front and middle seat shoulder belts of the Jeep Grand Cherokee L are height-adjustable to accommodate a wide variety of driver and passenger heights.

The E-Class All-Terrain Wagon doesn’t offer a back seat reminder.
The Jeep Grand Cherokee L has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection.

The E-Class All-Terrain Wagon doesn’t offer a front passenger side knee airbag.
The Grand Cherokee L has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash.

A passive infrared night vision system optional on the Grand Cherokee L Overland/Summit helps the driver to more easily detect people, animals or other objects in front of the vehicle at night.

To help make backing out of a parking space safer, the Grand Cherokee L has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the E-Class All-Terrain Wagon.
