For enhanced safety, the front and second-row seat shoulder belts of the Toyota Highlander 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 BMW X4 doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Toyota Highlander Hybrid 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 BMW X4 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 Highlander Hybrid are reminded to check the back seat if they opened the rear door before starting out. The X4 doesn’t offer a back seat reminder.
Both the Highlander Hybrid and X4 have rear cross-traffic warning, but the Highlander Hybrid Limited/Platinum has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The X4’s Cross Traffic Warning doesn’t automatically brake.
Both the Highlander Hybrid and the X4 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The Toyota Highlander Hybrid achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The X4 has not yet been evaluated by the IIHS for 2024.
