Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 1-68.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
in ate while someone is working on your vehicle. Your
dealer and the service manual have information
about servicing your vehicle and the airbag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still in ate during improper service.
You can be injured if you are close to an
airbag when it in ates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is quali ed to do so.
The airbag system does not need regular maintenance.

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 Service 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 modi ed. 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, the
overhead console, 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 5-88.
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 frontal airbag, or
an airbag covering (if equipped) on a seatback, 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 frontal airbag, or both
the airbag module and the seatback for seating
positions with a side impact airbag (if equipped.)
Do not open or break the airbag coverings.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system was not being used at the time of
the collision.
If an airbag in ates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
If an airbag in ates you will also need to replace the
driver and front passenger’s safety belt retractor
assembly. Be sure to do so. Then the new retractor
assembly will be there to help protect you in a collision.
After a crash you may need to replace the driver and
front passenger’s safety belt retractor assemblies, even
if an airbag has not deployed. The driver and front
passenger’s safety belt retractor assemblies contain the
safety belt pretensioners. Have your safety belt
pretensioners checked if your vehicle has been in a
collision, or if your airbag readiness light stays on after
you start your vehicle or while you are driving. See
Airbag Readiness Light on page 3-27.

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
quali ed technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked, and
the trunk can be unlatched from about 3 feet (1 m) up to
65 feet (20 m) away with the remote keyless entry
transmitter.
If your vehicle has the remote start feature you can also
start your vehicle with the remote keyless entry
transmitter. Your remote keyless entry transmitter, with
the remote start button, provides an increased range
of 195 feet (60 m) away. However, the range may
be less while the vehicle is running. As a result, you
may need to be closer to your vehicle to turn it off than
you were to turn it on.
There are other conditions which can affect the
performance of the transmitter. SeeRemote Keyless
Entry System on page 2-3.
