For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX50 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Toyota Highlander doesn’t offer pretensioners for its second-row seat belts.
The Infiniti QX50 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Highlander doesn’t offer a front passenger side knee airbag.
The QX50 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. Only the Highlander LE/XLE/XSE/Limited/Platinum offers a blind spot warning system.
To help make backing out of a parking space safer, the QX50 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Only the Highlander LE/XLE/XSE/Limited/Platinum has a rear cross-path warning system.
Both the QX50 and the Highlander have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive and around view monitors.
