Servicing Your Air Bag-Equipped Vehicle
The air bag affects how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
inflate while someone is working on your vehicle. Your
GM dealer and the service manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, see "Service and Owner
Publications" in the Index.
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 wires wrapped with yellow tape,
or yellow connectors. They are probably part of
the
air
bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do so.

The air bag system does not need regular maintenance.
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 bag 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
. I
air bags from wor@ng properly in a crash.
What if
I add a snow plow? Will it keep the air
bag from working properly?
A:
We've designed our air bag systems to work
properly under a wide range of conditions,
including snow plowing with vehicles equipped
with the optional Snow Plow Prep Package
(RPO VYU). But don't change or defeat the
snow plow's "tripping mechanism." If you do,
it can damage your snow plow and your vehicle,
and it may cause an air bag inflation.
