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 Aston Martin DBX 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 DBX doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Grand Cherokee 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 DBX doesn’t offer automatic braking for stationary objects directly to the rear.
A passive infrared night vision system optional on the Grand Cherokee Limited Reserve/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 DBX doesn’t offer a night vision system.
The Grand Cherokee Summit’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The DBX doesn’t offer a driver alert monitor.
Both the Grand Cherokee and the DBX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear 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 and around view monitors.
