For enhanced safety, the front and rear seat shoulder belts of the Honda Prologue 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 Jeep Grand Cherokee doesn’t offer pretensioners for its rear seat belts.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Honda Prologue achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Jeep Grand Cherokee has not been tested.
Both the Prologue and Grand Cherokee have rear cross-traffic warning, but the Prologue has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Grand Cherokee’s Rear Cross Path Detection doesn’t automatically brake.
Both the Prologue and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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 and available around view monitors.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Honda Prologue is safer than the Jeep Grand Cherokee:
