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 Land Rover Discovery Sport doesn’t offer height-adjustable 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 Discovery Sport 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 Discovery Sport 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 Discovery Sport doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The Grand Cherokee L has standard ParkSense Rear Park Assist with Stop that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Discovery Sport doesn’t offer automatic braking for stationary objects directly to the rear.
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 Discovery Sport doesn’t offer a night vision system.
The Grand Cherokee L (except Laredo) offers an optional 360-degree camera to allow the driver to see objects all around the vehicle on a screen. The Discovery Sport only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Grand Cherokee L and the Discovery Sport have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and driver alert monitors.
