Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system
from working properly. Also, the airbag system
may not work properly if you relocate any of the
airbag 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. SeeCustomer Satisfaction Procedure
on page 7-2.
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module, steering wheel, instrument panel, ceiling
headliner, ceiling and pillar garnish trim,
roof-mounted airbag modules, or airbag wiring can
affect the operation of the airbag system. If you have
questions, call Customer Assistance. The phone
numbers and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer Satisfaction
Procedure on page 7-2.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired. SeeCare of Safety Belts on
page 5-87for more information.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.Also look for any opened or broken airbag covers, and
have them repaired or replaced. The airbag system
does not need regular maintenance.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the side
impact airbag covering (if equipped) on the ceiling
near the side windows, the airbag may not work
properly. You may have to replace the airbag
module in the steering wheel, both the airbag
module and the instrument panel for the right front
passenger’s airbag, or side impact airbag module
and ceiling covering for roof-mounted side impact
airbags (if equipped.) Do not open or break the
airbag coverings.
