For enhanced safety, the front seat shoulder belts of the Jeep Grand Cherokee 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 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 are reminded to check the back seat if they opened the rear door before starting out. The Discovery doesn’t offer a back seat reminder.
The Jeep Grand Cherokee has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Discovery doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Grand Cherokee has a standard backup collision prevention system that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Discovery doesn’t offer backup collision prevention brakes.
A passive infrared night vision system optional on the Grand Cherokee Trailhawk/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 doesn’t offer a night vision system.
Both the Grand Cherokee and the Discovery have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, around view monitors and driver alert monitors.
