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 570.
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, rollover sensor
module, instrument panel, steering wheel,
ceiling headliner, ceiling and pillar garnish trim,
roof-mounted rollover 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 570.

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. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 530for 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 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 rollover airbags. 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.
109

If an airbag inates, you will need to replace
airbag system parts. See the part on the airbag
system earlier in this section.
If the frontal airbags inate 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 the frontal airbags have 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 229.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can
easily open the doors and fall out
of a moving vehicle. When a door is
locked, the handle will not open it.
You increase the chance of being
thrown out of the vehicle in a crash if
the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)
CAUTION: (Continued)

Young children who get into unlocked
vehicles may be unable to get out. A
child can be overcome by extreme
heat and can suffer permanent injuries
or even death from heat stroke.
Always lock your vehicle whenever
you leave it.
Outsiders can easily enter through an
unlocked door when you slow down
or stop your vehicle. Locking your
doors can help prevent this from
happening.

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will be provided for several seconds to remind
people to buckle their safety belts. The driver safety
belt light will also be provided and stay on for
several seconds, then it will ash for several more.
You should buckle your seat belt.
This chime and light will
be repeated if the driver
remains unbuckled
and the vehicle
is in motion.
If the driver’s belt is buckled, neither the chime nor
the light will come on.
SeePassenger Sensing System on page 101for
more information.
Passenger Safety Belt Reminder
Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety
belt. This would only occur if the passenger airbag
is enabled. SeePassenger Sensing System on
page 101for more information. The passenger
safety belt light will also come on and stay on for
several seconds, then it will ash for several more.
This chime and light will
be repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
228

Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the
engine is not running,
as a check to show you
it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this
light is on could drain your battery.
When this light comes on the DIC will also display
the battery not charging message. SeeDIC
Warnings and Messages on page 252.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
Voltmeter Gage
When your engine is not
running, but the ignition
is in RUN, this gage
shows your battery’s
state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. The gage
may transition from a higher to lower or a lower to
higher reading, this is normal. Readings between
the low and high warning zones indicate the
normal operating range.

Here are some ways in which you can help avoid
distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering
wheel controls if the vehicle has them.
Notice:Before adding any sound equipment
to your vehicle, such as an audio system,
CD player, CB radio, mobile telephone,
or two-way radio, make sure that it can be
added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be
added, it is very important to do it properly.
Added sound equipment may interfere with the
operation of your vehicle’s engine, radio, or
other systems, and even damage them.
Your vehicle’s systems may interfere with the
operation of sound equipment that has
been added.Notice:The chime signals related to safety
belts, parking brake, and other functions
of your vehicle operate through the
radio/entertainment system. If that equipment
is replaced or additional equipment is added
to your vehicle, the chimes may not work. Make
sure that replacement or additional equipment
is compatible with your vehicle before
installing it. SeeAccessories and Modifications
on page 421.
Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, the audio
system can be played even after the ignition
is turned off. SeeRetained Accessory Power
(RAP) on page 141for more information.

Your Driving, the Road, and
Your Vehicle
Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in
your vehicle: Buckle up. SeeSafety Belts: They
Are for Everyone on page 38.
{CAUTION:
Defensive driving really means “Be ready
for anything.” On city streets, rural roads,
or expressways, it means “Always expect
the unexpected.” Assume that pedestrians
or other drivers are going to be careless
and make mistakes. Anticipate what they
might do and be ready. Rear-end
collisions are about the most preventable
of accidents. Yet they are common. Allow
enough following distance. Defensive
driving requires that a driver concentrate
on the driving task. Anything that
distracts from the driving task makes
proper defensive driving more difficult
and can even cause a collision, with
resulting injury. Ask a passenger to help
do these things, or pull off the road in a
safe place to do them. These simple
defensive driving techniques could save
your life.
