To avoid activating the alarm by accident:
The vehicle should be locked with the key
doors are closed if you don’t want to activate the
Always unlock a door with a key or use the remote
keyless entry transmitter. (Pressing the unlock button
on the remote keyless entry transmitter disables the
deterrent system.) Unlocking a door any other
way will activate the alarm. Cycling the ignition
without disarming the theft
deterrent system will
also activate the alarm.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm by
using the remote keyless entry transmitter. The alarm
won’t stop if you try to unlock a door in any other way.
Testing the Alarm
From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
From outside the vehicle, with the door open, lock
the vehicle using the power door lock or the remote
keyless entry transmitter and close the door. Wait
30 seconds until the SECURITY light stops flashing.
Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
headlamps will flash.
If the alarm does not sound when it should, check to see
if the horn works. The horn fuse may be blown. To
replace the fuse, see “Fuses and Circuit Breakers” in the
Index. If the fuse does not need to be replaced, you may
need to have your vehicle serviced.
To reduce the possibility of theft, always activate the
deterrent system when leaving

Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
The system works when you turn the key to ON (II). The key
uses a transponder that matches an immobilizer control unit
in your vehicle. The correct key will start the vehicle.
When the system senses that someone is using the wrong
key, it may start but it will not continue to run. If someone
tries to start your vehicle again or uses another key during
this time, the shutdown will start over again. This
discourages someone from randomly trying different keys
with different transponders in an attempt to make a match.
If the engine cannot be started, turn the key in the
ignition to ON (II). Wait approximately two seconds;
then start your vehicle again.
If the engine still won’t start, try another key. You may
also want to check the fuses (see “Fuses and Circuit
Breakers” in the Index). If the engine won’t start with
the other key, your vehicle needs service. If your vehicle
does start, the first key may be faulty. See your dealer.
If you lose or damage a key or you cannot start the
engine, see your dealer. If a key is lost, bring all
remaining keys to your dealer for re

Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever returns when it is released.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned
out front signal
bulb. (This does not occur with a burned
out rear bulb.)
Other drivers won’t see the turn signal. Replace
out bulbs to help avoid possible accidents.
Check the fuse (see “Fuses and Circuit Breakers” in the
Index) and for burned
out bulbs if the arrow fails to
work when signaling a turn.

This feature uses the high
beam headlamps to signal the
driver in front of you that you want to pass. This feature
will work with either the headlamps on or off.
To use, pull the turn signal lever toward you and release.
Move the lever on the passenger’s side of the
steering wheel up and down to control the wipers.
Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn off all lamps that aren’t needed as well
as the radios. This will avoid sparks and help save
both batteries. In addition, it could save the radio!
Open the hoods and locate the batteries. You’ll also

Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You don’t
need to add water to the ACDelco Freedom
battery installed in every new GM vehicle. But if
a battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take care
of that first. If you don’t, explosive gas could
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top
quality GM brake
parts. When you replace parts of your braking
for example, when your brake linings wear
down and you have to have new ones put in
you get new approved GM replacement parts. If you
don’t, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
for the worse. The braking
performance you’ve come to expect can change in many
other ways if someone puts in the wrong replacement
Your new vehicle comes with an ACDelco Freedom
battery. When it’s time for a new battery, we recommend
an ACDelco Freedom battery. Get one that has the

Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See “Jump Starting” in the Index
for tips on working around a battery without
After a power loss, such as disconnecting the battery or
removing the MaxiFuses
in the power distribution fuse
block, the following steps must be performed to
calibrate the Electronic Throttle Control. If this is not
done, the engine will not run properly.
Turn the ignition key to RUN . Do not start
Leave the ignition in RUN for at least three minutes
so that the electronic throttle control will cycle and
learn its home position.
Turn the ignition to OFF.
Start and run the engine for at least 30 seconds.
Also, for your audio system, see “Theft
Feature” in the Index.
Add-On Electrical Equipment
Don’t add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add
on electrical equipment can
keep other components from working as
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see “Servicing
Your Air Bag
Equipped Vehicle” in the Index.
The headlamp wiring has several fuses which are
powered by a MaxiFuse
. An electrical overload will
cause the lamps to go on and off, or in some cases to
remain off. If this happens, have the headlamp wiring
checked right away.
Windshield Wiper Fuses
If the windshield wiper motor overheats due to heavy
snow or ice, the wipers will stop until the motor cools.
If the overload is caused by some electrical problem, be
sure to have it fixed.
Power Windows and Other Power Options
Circuit breakers 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 fixed or goes away.
Power Distribution Fuse Block
This fuse block is attached to the engine compartment
relay center located on top of the battery. Simply lift the
lid to open. If you have any questions about the power
distribution fuse block, consult your dealer.
Note: If a power loss has occurred, such as
disconnecting the battery or removing the MaxiFuses in
the power distribution fuse block, there are steps that
must be followed to calibrate the Electronic Throttle
Control (ETC). If these steps are not done, the engine
will not run properly. For information regarding these
steps, see “Battery” earlier in this section.
Fuses and Circuit Breakers
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 fires 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 you
replace a bad fuse with a new one of the identical size
If you ever have a problem on the road and don’t have a
spare fuse, you can borrow one that has the same
amperage. Pick some feature of your vehicle that you
can get along without
like the radio or cigarette
and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the
instrument panel fuse block and the engine compartment
Instrument Panel Fuse Block (Driver’s Side)
The fuse block is located below the steering wheel on
the driver’s side. Using a screwdriver, loosen the two
trim fasteners under the trim panel and pull the trim
panel away from the instrument panel to access.
