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. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes E-Class All-Terrain Wagon doesn’t offer height-adjustable middle seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Grand Cherokee L are reminded to check the back seat if they opened the rear door before starting out. 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. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. 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. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The E-Class All-Terrain Wagon doesn’t offer a whiplash protection system.
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. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The E-Class All-Terrain Wagon doesn’t offer a night vision system.
The Grand Cherokee L’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the E-Class All-Terrain Wagon.
To help make backing out of a parking space safer, the Grand Cherokee L has standard Rear Cross Path Detection, helping the driver avoid collisions. Mercedes charges extra for Rear Cross-Traffic Alert on the E-Class All-Terrain Wagon.
Both the Grand Cherokee L and the E-Class All-Terrain Wagon have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, available all wheel drive, around view monitors and driver alert monitors.
The Jeep Grand Cherokee L achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The E-Class All-Terrain Wagon has not yet been evaluated by the IIHS for 2024.
