Servicing Your Air Bag-Equipped Vehicle

Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
air bag systems. To purchase a service manual, see
“Service and Owner Publications” in the Index.

CAUTION:

For up to two minutes after the ignition key is
turned off and the battery is disconnected, an 
air bag can still inflate during improper service.
You can be injured if you are close to an air bag
when it inflates. Avoid yellow connectors. They
are probably part of the air bag systems. Be sure
to follow proper service procedures, and make
sure the person performing work for you is
qualified to do so.

The air bag systems do not need regular maintenance.

Adding Equipment to Your 
Air Bag-Equipped Vehicle

Q:

If I add a push bumper or 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 or
sides 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 or side 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 in this
manual. See “Customer Satisfaction Procedure” 
in the Index.
