Mercedes-Benz GL-Class: Driver's knee bag

Driver's knee bag 1 provides additional protection for the driver against:
• knee injuries
• thigh injuries
• lower leg injuries
Driver's knee bag 1 deploys below the steering wheel. During a frontal impact, if the system determines that air bag deployment can offer additional protection to that provided by the seat belt, driver's knee bag 1 is deployed along with the driver's air bag. The driver's knee bag 1 operates best in conjunction with a properly positioned and fastened seat belt.
Front air bags
The front air bags increase protection for the
driver's and front-passenger's head and
chest.
