Adding Equipment to
Your Airbag-Equipped
Vehicle
Q:Is there anything I might add
to or change about the vehicle
that could keep the airbags
from working properly?
A:Yes. If you add things that
change the vehicle’s frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Changing or
moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,
steering wheel, instrument
panel, roof-rail airbag modules,
ceiling headliner or pillar
garnish trim, front sensors,
or airbag wiring can affect the
operation of the airbag system.
In addition, the vehicle has a
passenger sensing system for the
right front passenger position,which includes sensors that are
part of the passenger’s seat.
The passenger sensing system
may not operate properly if the
original seat trim is replaced
with non-GM covers, upholstery
or trim, or with GM covers,
upholstery or trim designed for a
different vehicle. Any object, such
as an aftermarket seat heater or a
comfort enhancing pad or device,
installed under or on top of the
seat fabric, could also interfere
with the operation of the
passenger sensing system.
This could either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system
from properly turning off the
passenger airbag(s). See
Passenger Sensing System
on page 1-30.
If you have any questions about
this, you should contact Customer
Assistance before you modify
your vehicle. The phone numbersand addresses for Customer
Assistance are in Step Two of the
Customer Satisfaction Procedure
in this manual. SeeCustomer
Satisfaction Procedure on
page 11-1.
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: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 11-1.
In addition, your dealer/retailer and
the service manual have information
about the location of the airbag
sensors, sensing and diagnostic
module and airbag wiring.

Rear Door Security
Locks
Your vehicle has rear door security
locks to prevent passengers from
opening the rear doors from the
inside.
Open the rear doors to access the
security locks on the inside edge
of each door.To set the locks, insert a key into
the slot and turn it to the horizontal
position. The door can only be
opened from the outside with the
door unlocked. To return the door to
normal operation, turn the slot to
the vertical position.
Liftgate
{CAUTION
It can be dangerous to drive
with the liftgate open because
carbon monoxide (CO) gas can
come into your vehicle. You
cannot see or smell CO. It can
cause unconsciousness and
even death.
(Continued)
CAUTION (Continued)
If you must drive with the liftgate
open, or if electrical wiring or
other cable connections must
pass through the seal between
the body and the liftgate:
Make sure all other windows
are shut.
Turn the fan on your heating
or cooling system to its
highest speed with the
recirculation mode off. That
will force outside air into your
vehicle. See Climate Control
System in the index.
If you have air outlets on or
under the instrument panel,
open them all the way.

DIC Warnings and
Messages (Base and
Uplevel Systems)
Messages are displayed on the DIC
to notify the driver that the status of
the vehicle has changed and that
some action may be needed by
the driver to correct the condition.
Multiple messages may appear
one after another.
The DIC monitors some uid levels,
battery of the Remote Keyless Entry
(RKE) transmitter, the theft-deterrent
system on vehicles with this feature,
the brake light switch, and important
exterior lights, including wiring and
fuses.Some messages may not require
immediate action, but you can
acknowledge that you received the
messages and to clear them from the
display by doing one of the following:
Press the OK button on the base
level audio system.
Press the multifunction knob, if
your vehicle has this feature,
on the uplevel audio system.
Press the left thumbwheel, if your
vehicle has this feature, on the
steering wheel.
If there are several warning
messages, acknowledge them
one at a time.Some messages cannot be cleared
from the DIC display because they
are more urgent. These messages
require action before they can
be cleared. You should take any
messages that appear on the display
seriously and remember that clearing
the messages will only make the
messages disappear, not correct
the problem.
Warning messages for the uplevel
DIC follow. On the base level
DIC, messages appear in an
abbreviated form.
Brakelight check---
This message displays when there
is a problem with the vehicle lighting.
The source of the problem is

Electrical System
Add-On Electrical
Equipment
Notice:Do not add anything
electrical to your vehicle unless
you check with your dealer/retailer
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, see
Servicing Your Airbag-Equipped
Vehicle on page 1-34.Headlamp Wiring
The headlamp wiring is protected
by fuses in the fuse block.
An electrical overload will cause
the lamps to turn off. If this happens,
have your headlamp wiring checked
right away.
Vehicle Service and Care 9-33
ProCarManuals.com

Windshield Wiper Fuses
The windshield wiper motor is
protected by a circuit breaker and a
fuse. If the motor overheats due
to heavy snow, etc., 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
Circuit breakers in the fuse block
protect the power windows and
other power accessories. When the
current load is too heavy, the
circuit breaker opens and closes,
protecting the circuit until the
problem is xed or goes away.
Fuses
The wiring circuits in your vehicle
are protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by
electrical problems.
Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
to replace a bad fuse with a new one
of the identical size and rating.
There are two fuse blocks in
your vehicle: one in the engine
compartment and one in the trunk.
There is a fuse puller located
on the rear compartment fuse block.
SeeRear Compartment Fuse
Block on page 9-36. It can be used
to easily remove fuses from the
fuse block.
Engine Compartment
Fuse Block
The engine compartment fuse block
is located in the front left side of
the engine compartment.Engine
Compartment Overview on
page 9-6.
To open the fuse block cover,
insert a tool into the latch and turn.
Pull up on the cover to remove.
Notice:Spilling liquid on any
electrical components on
your vehicle may damage it.
Always keep the covers on any
electrical component.
