The Mazda CX-5 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 Forester doesn’t offer a front passenger side knee airbag.
The CX-5 has a standard Secondary Collision Reduction System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Forester doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The CX-5 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 and moves the vehicle back into its lane. A system to reveal vehicles in the Forester’s blind spot costs extra.
To help make backing out of a parking space safer, the CX-5 has standard Rear Cross Traffic Alert and Smart Braking Support - Rear Crossing automatically engages the brakes to help avoid a collision. Subaru charges extra for Rear Cross Traffic Alert on the Forester and it’s not available on the Base and the Forester’s Rear Cross Traffic Alert does not include automatic braking.
Both the CX-5 and the Forester have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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, lane departure warning systems, rearview cameras and available around view monitors.
