2-13 Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for the
SECURITY message to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should but the
vehicle's headlamps flash, check to see if the horn
works. The horn fuse may be blown. To replace the fuse,
see ªFuses and Circuit Breakersº in the Index.
If the alarm does not sound or the vehicle's headlamps
do not flash, the vehicle should be serviced by an
authorized service center.
Passlock

Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
If the engine stalls and the SECURITY message flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the SECURITY message
comes on, you will be able to restart the engine if you
turn the engine off. However, your Passlock system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock at this
time. You may also want to check the fuse (see ªFuses
and Circuit Breakersº in the Index). See your dealer
for service.
In an emergency, call the GM Roadside Assistance
Center. See ªRoadside Assistanceº in the Index.

2-14
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the
long run if you follow these guidelines:

Keep your speed at 55 mph (88 km/h) or
less for the first 500 miles (805 km).

Don't drive at any one speed
-- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.
Ignition Positions
You can use your key to turn your ignition switch to five
different positions.
ACCESSORY (A): ACCESSORY lets you use things
like the radio, power windows and the windshield wipers
when the engine is off. Push in the key and turn it toward
you. Your steering wheel will remain locked, just as it
was before you inserted the key.
LOCK (B): This position locks your ignition, steering
wheel and transmission. It's a theft
-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.

2-15
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK. Use OFF if you must have your
vehicle in motion while the engine is off (for example,
if your vehicle is being pushed).
RUN (D): This is the position for driving.
START (E): This position starts your engine.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
Retained Accessory Power (If Equipped)
Your vehicle may be equipped with a Retained
Accessory Power (RAP) feature which will allow
certain features on your vehicle to continue to work up
to 20 minutes after the ignition key is turned to OFF.
Your radio, power windows and overhead console will
work when the ignition key is in RUN or ACCESSORY.
Once the key is turned from RUN to OFF, these features
will continue to work for up to 20 minutes or until a
door is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position
-- that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
NOTICE:
Don't try to shift to PARK (P) if your vehicle
is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when
your vehicle is stopped.

2-31
Parking Over Things That Burn
CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't park
over papers, leaves, dry grass or other things that
can burn.
Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.

2-34 Autoride
(If Equipped)
The Autoride
feature will provide a superior vehicle
ride and handling under a variety of passenger and
loading conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed, wheel
to body position, lift/dive and steering position of the
vehicle. The controller then sends signals to each shock
absorber to independently adjust the damping level to
provide the optimum vehicle ride.
Autoride also interacts with the Tow/Haul switch that,
when engaged, will provide additional control of the
shock absorbers. This additional control results in better
ride and handling characteristics when the vehicle is
loaded or towing a trailer. See ªTow/Haul Modeº in
the Index for more information.
Locking Rear Axle
If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, sand
or gravel. It works like a standard axle most of the time,
but when one of the rear wheels has no traction and the
other does, this feature will allow the wheel with
traction to move the vehicle.
Windows
Manual Windows
Turn the hand crank on each door to raise or lower
manual windows.
Power Windows (If Equipped)
If you have the optional power windows, the controls
are located on each of the side doors.

2-35
The driver's door has a switch for the passenger
windows as well. Your power windows will work when
the ignition has been turned to ACCESSORY or RUN
or when Retained Accessory Power (RAP) is present.
See ªRetained Accessory Powerº in the Index.
Press the rear of the switch with the power window
symbol on it to lower the window or the front to raise it.
The driver's window also has an express down feature
that allows the window to be lowered without holding
the switch. Press and hold the rear of the window switch
for one second to activate the express down mode.
The express down mode can be canceled at any time
by pressing the opposite side of the switch. To open the
window partway, lightly tap the switch until the window
is at the desired position.
If you have power windows, the power window switch has
a lockout feature. This feature prevents the rear windows
from operating except from the driver's position when the
front driver's side button labeled WINDOW LOCK is
engaged. When the button is not engaged, the rear power
windows will operate again.Horn
To sound the horn, press the center pad on the
steering wheel.
Tilt Wheel (If Equipped)
The tilt steering wheel
allows you to adjust the
steering wheel before
you drive.
You can also raise it to the highest level to give your
legs more room when you enter and exit the vehicle.
To tilt the wheel, hold the steering wheel and pull the
lever located on the lower left of the column. Move the
steering wheel to a comfortable level, then release the
lever to lock the wheel in place.

2-39 Windshield Washer
There is a paddle marked with the windshield washer
symbol at the top of the multifunction lever. To spray
washer fluid on the windshield, push the paddle. The
wipers will clear the window and then either stop or
return to your preset speed.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
Rear Window Washer/Wiper
This switch is located on the
instrument panel.
To turn the rear wiper on, turn the switch to either
1 or 2. For long delayed wiping, turn the switch to 1.
For short delayed wiping, turn the switch to 2. To turn
the wiper off, turn the switch to 0.
To wash the window, press the knob.
The rear window washer uses the same fluid bottle
as the windshield washer. However, the rear window
washer will run out of fluid before the windshield
washer. If you can wash your windshield but not
your rear windows, check the fluid level.

2-50
In order to calibrate, the letter ªCALº must be
displayed in the mirror compass windows. If ªCALº
is not displayed, push in the ªCOMPº button for
approximately eight seconds or until the letter ªCALº
is displayed.
The compass can be calibrated in one of two ways:

Drive the vehicle in circles at five mph (8 km/h) or
less until the display reads a direction, or

Drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.
Compass Variance
The compass is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass to
compensate for compass variance if you live outside
zone eight. Under certain circumstances, as during a
long distance cross
-country trip, it will be necessary to
adjust for compass variance. Compass variance is the
difference between earth's magnetic north and true
geographic north. If not adjusted to account for compass
variance, your compass could give false readings.To adjust for compass variance:
1. Press and hold the COMP button, located at the
bottom of the mirror, for three seconds until a zone
number appears in the display.
2. Find your current location and variance zone number
on the following zone map.
3. Press the COMP button on the bottom of the mirror
until the new zone number appears in the display.
After you stop pressing the button in, the display
will show a compass direction within a few seconds.

2-52
Electrochromic Mirror Operation
The right side of the button, labeled TEMP and located
at the bottom of the mirror, turns the electrochromic
mirror on and off. An indicator light, located to the
right of the TEMP button, will come on when the
electrochromic mirror is turned on. To turn the mirror
on, press and hold the TEMP button for 15 seconds.
To turn the mirror off, press and hold the TEMP button
for 15 seconds. The indicator light will turn off.
Compass Operation
With the ignition on, the compass will show two character
boxes. The mirror will display the compass heading.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.Compass Calibration
The compass may need calibration if:

After five seconds, the display does not show a
compass heading (ªNº for North, for example),
there may be a strong magnetic field interfering with
the compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item.

The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, the letter ªCALº must be displayed in
the mirror compass windows. If ªCALº is not displayed,
push in the ªCOMPº button for approximately eight seconds
or until the letter ªCALº is displayed.
The compass can be calibrated in one of two ways:

Drive the vehicle in circles at five mph (8 km/h) or
less until the display reads a direction, or

Drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.

2-54 Outside Manual Adjust Mirrors
Adjust your outside mirrors so you can just see the side of
your vehicle and have a clear view of objects behind you.
The mirrors can be folded in to enter narrow doorways.
The use of hood
-mounted air deflectors and add-on
convex mirror attachments may adversely affect
mirror performance.
Camper-Type Outside Mirrors (If Equipped)
