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 Crosstrek are reminded to check the back seat if they opened the rear door before starting out. The 500X doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Crosstrek Limited/Wilderness has standard Reverse Automatic Braking that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The 500X doesn’t offer backup collision prevention brakes.
When descending a steep, off-road slope, the Crosstrek’s standard Hill Descent Control allows you to creep down safely. The 500X doesn’t offer Hill Descent Control.
The Crosstrek’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the 500X and is only available on 500X Sport.
Both the Crosstrek and the 500X have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.
