The Toyota Camry has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 Legacy doesn't offer a front passenger side knee airbag.
The Camry has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Legacy 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 Camry XLE/XSE offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Legacy only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn't help with obstacles to the front or sides.
The Camry 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 Legacy's blind spot costs extra.
To help make backing out of a parking space safer, the Camry has standard Rear Cross-Traffic Alert and optional Rear Cross-Traffic Braking on the XLE/XSE automatically engages the brakes to help avoid a collision. Subaru charges extra for Rear Cross Traffic Alert on the Legacy and its not available on the Base and the Legacy's Rear Cross Traffic Alert does not include automatic braking.
Both the Camry and the Legacy 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
