For enhanced safety, the front and second-row seat shoulder belts of the Hyundai Santa Fe Hybrid 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.
Both the Santa Fe Hybrid and Grand Cherokee have child safety locks to prevent children from opening the rear doors. The Santa Fe Hybrid has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Grand Cherokee’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
Both the Santa Fe Hybrid and Grand Cherokee have rear cross-traffic warning, but the Santa Fe Hybrid has Rear Cross-Traffic Collision-Avoidance Assist (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 Santa Fe Hybrid and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, available all wheel drive and around view monitors.
