The Acura ADX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 Crosstrek doesn’t offer a front passenger side knee airbag.
The ADX A-Spec offers an optional Multiview Camera System to allow the driver to see objects all around the vehicle on a screen. The Crosstrek only offers a rear monitor.
The ADX has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Crosstrek’s blind spot costs extra.
To help make backing out of a parking space safer, the ADX has standard Rear Cross Traffic Monitor, helping the driver avoid collisions. Subaru charges extra for Rear Cross Traffic Alert on the Crosstrek and its not available on the Base.
Both the ADX and the Crosstrek have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, pre-tensioning seatbelts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors and available all-wheel drive.
