Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:
If I add a push bumper or a bicycle rack to the
front of my vehicle, will it keep the air bags
from working properly?
A:
As long as the push bumper or bicycle rack is
attached to your vehicle so that the vehicle's
basic structure isn't changed, it's not likely to keep
the air bags from working properly in a crash.

Q:
Is there anything I might add to the front of the
vehicle that could keep the air bags from
working properly?
A:
Yes. If you add things that change your vehicle's
frame, bumper system, front end sheet metal or
height, they may keep the air bag system
from working properly. Also, the air bag system
may not work properly if you relocate any of the air
bag sensors. If you have any questions about
this, you should contact Customer Assistance
before you modify your vehicle. The phone
numbers and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure on page 7-2 .
