Both the Q5 and Forester have child safety locks to prevent children from opening the rear doors. The Q5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Forester’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Q5 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Forester doesn’t offer front seat center airbags.
The Q5 has a standard Secondary Collision Brake Assist, 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.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The Q5 has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Forester doesn’t offer a system that can receive automated systems from infrastructure.
The Q5 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 Forester’s blind spot costs extra.
To help make backing out of a parking space safer, the Q5 has standard Rear Cross-Traffic Assist and Automatic Brake Activation 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 Q5 and the Forester 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, 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.
