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 414.
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.

Trunk
To release the trunk lid from the outside, use the
key or the remote keyless entry transmitter, if
equipped.
{CAUTION:
It can be dangerous to drive with the
trunk lid open because carbon monoxide
(CO) gas can come into your vehicle.
You cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the trunk lid open or if
CAUTION: (Continued)
CAUTION: (Continued)
electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle.
See Climate Control System.
If you have air outlets on or under
the instrument panel, open them all
the way.
SeeEngine Exhaust on page 128.

Passenger Safety Belt
Reminder Light
If your vehicle has this feature, 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. See
Passenger Sensing System on page 77for 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 light and chime
reminder 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.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol.
The system checks the airbag’s electrical system
for malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensor, the airbag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag
System on page 68.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring.
Check with your dealer. The arrows on your
instrument panel will ash whenever you signal a
turn or lane change. Properly hooked up, the
trailer lamps will also ash, telling other drivers
you are about to turn, change lanes or stop.
When towing a trailer, the arrows on your
instrument panel will ash for turns even if the
bulbs on the trailer are burned out. Thus, you may
think drivers behind you are seeing your signal
when they are not. It is important to check
occasionally to be sure the trailer bulbs are
still working.
Driving on Grades
Notice:Do not tow on steep continuous
grades exceeding 6 miles (9.6 km). Extended,
higher than normal engine and transmission
temperatures may result and damage your
vehicle. Frequent stops are very important to
allow the engine and transmission to cool.Reduce speed and shift to a lower gearbefore
you start down a long or steep downgrade. If you
do not shift down, you might have to use your
brakes so much that they would get hot and
no longer work well.
Pay attention to the engine coolant gage. If the
indicator is in the red area, turn off the air
conditioning to reduce engine load. SeeEngine
Overheating on page 309.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your
vehicle may experience more transaxle shifting.
A COOLING MODE ON message may also appear
in the DIC. This alerts the driver that the shifting
mode is in progress and is aiding engine cooling.
SeeDIC Warnings and Messages on page 184
for more information.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer rst.
Some electrical equipment can damage your
vehicle and the damage would not be covered
by your warranty. Some add-on electrical
equipment can keep other components from
working as they should.
Add-on equipment can drain your vehicle’s
battery, even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 82.
Headlamp Wiring
The headlamp wiring is protected by fuses.
Should your headlamps fail to function, have
your headlamp system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow or ice, the wiper will stop
until the motor cools. If the overload is caused
by some electrical problem, have it xed.
Power Windows and Other
Power Options
Fuses in the fuse block protect the power windows.
When the current load is too heavy, the fuse opens
protecting the circuit until the problem is xed.
