Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Active Knee Protection
The Active Knee Protection consists of a knee airbag located on the front driver and passenger sides of the vehicle. The knee airbag prevent the driver from sliding under the seat belt during an impact. This effect is known as "submarining". This effect is counteracted by the knee airbag and initiates a controlled forward shift of the upper body.
This increases the effect of the seatbelt and the airbag.
The knee airbag is available on the E65, E85 and E63/64.
