For enhanced safety, the front and rear seat shoulder belts of the Jeep Wrangler have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Porsche Cayenne doesn’t offer pretensioners for its rear 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 Wrangler 4-Door are reminded to check the back seat if they opened the rear door before starting out. The Cayenne doesn’t offer a back seat reminder.
Both the Wrangler and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available crash mitigating brakes, daytime running lights, blind spot warning systems, rear parking sensors and rear cross-path warning.
