Driver and passenger supplemental knee air bag
Driver’s side
The knee air bag is located in the knee bolster, on the driver’s and passenger’s side. All of the information, cautions and warnings in this manual apply and must be followed. The knee air bag is designed to inflate in higher severity frontal collisions, although it may inflate if the forces in another type of collision are similar to those of a higher severity frontal impact. It may not inflate in certain collisions.
Passenger’s side
