The Cadillac CT5-V 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.

The AMG E-Class Sedan doesn’t offer a front passenger side knee airbag.
