Both the Soul and Crosstrek offer rear cross-traffic warning, but the Soul with Rear Cross-Traffic Collision Warning also has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Crosstrek’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Soul and the Crosstrek have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, rearview cameras, driver alert monitors and available blind spot warning systems.
