Retained Accessory Power (RAP)
Your vehicle is equipped with Retained Accessory
Power (RAP) which will allow certain features of your
vehicle to continue working for up to 20 minutes after the
ignition key is turned to LOCK.
Your radio, front wipers, sunroof, if equipped, and power
windows will work when the ignition key is in ON or
ACC. Once the key is turned from ON to LOCK, these
features will continue to work for up to 20 minutes
or until a door is opened.
Starting the Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not 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.
Manual Transmission
The gear selector should be in NEUTRAL and the
parking brake engaged. Hold the clutch pedal to the oor
and start the engine. Your vehicle will not start if the
clutch pedal is not all the way down — that is a
safety feature.
Starting Your Engine
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If the engine does not start within 10 seconds, push
the accelerator pedal all the way to the oor, while
you hold the ignition key in START. When the
engine starts, let go of the key and let up on the
accelerator pedal. Wait about 15 seconds between
each try.

Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
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 cannot
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 were not done correctly.
Your vehicle or exhaust system had been
modied 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 xed immediately.

Compass Calibration
The compass may need calibration if one of the
following occurs:
If CAL is displayed while driving in the vehicle.
After approximately ve seconds, the display does
not show a compass heading (N for North, for
example), there may be a strong magnetic eld
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, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, push
in the on/off button for approximately eight seconds
or until CAL is displayed.
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display
reads a direction.
Cleaning the Mirror
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.
Outside Power Mirrors
The outside power mirror
controls are located on the
driver’s door armrest.
To adjust the power mirrors, do the following:
1. Press the top of the selector switch to choose the
driver’s side mirror. Press the bottom of the selector
switch to choose the passenger’s side mirror.
2. Use the round, four-way control pad to move the
mirror in the desired direction.
If the mirror begins making a ratcheting sound, the
mirror has reached the end of its travel and can go no
farther in that direction. To stop the sound, reverse
the mirror direction using the control pad.
The mirrors can be manually folded inward to prevent
damage when going through an automatic car wash
or conned space. Pull the mirror toward the vehicle to
fold. To return the mirror to its original position, push
outward. Be sure to return both mirrors to the unfolded
position before driving.

Windshield Washer
L(Washer Fluid):There is a paddle marked with the
windshield washer symbol at the top of the multifunction
lever. To spray washer uid 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, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
Rear Window Wiper/Washer
This knob is located on the
instrument panel below the
climate controls.
Z(Rear Wiper):To turn the rear wiper on, turn the
knob to either 1 or 2. For a slower wiping speed, turn the
knob to 1. For a faster wiping speed, turn the knob to 2.
0 (Off):To turn the wiper off, turn the knob to
this symbol.
=(Washer Fluid):To wash and wipe the window,
press the button within the knob with this symbol.
The rear window washer uses the same uid bottle as
the windshield washer. However, the rear window
washer will run out of uid before the windshield washer.
If you can wash your windshield but not your rear
windows, check the uid level.
3-10

9(Off):Turn the center knob to this position to turn
the fan off. With the fan off, you may still experience
airow from the system that increases with vehicle
speed depending on the mode and temperature settings.
Enable recirculation mode to stop this airow from
occurring.
The right knob on the control panel is used to direct the
airow inside your vehicle. Turn the knob to select
one of the following modes:
@(Recirculation):Press the center knob on the
control panel to recirculate air inside the vehicle
and prevent outside air from coming in. It can be used
to prevent outside odors from entering your vehicle
and cool the air inside your vehicle more quickly. Press
this button to turn the recirculation mode on or off.
An indicator light on the button will come on to let you
know the recirculation mode is activated. This is normal.
Recirculation is available in the bi-level, and vent
modes. Recirculation is not available, and the light will
not come on, while in oor, oor/defog and defrost
mode. If recirculation is selected in these modes, the
indicator will ash three times indicating it is not
available in that mode.
H(Vent):Turn the right knob on the control panel to
this mode to direct air to the instrument panel outlets.
\(Bi-Level):Turn the right knob on the control panel
to this mode to direct air to the instrument panel outlets,
and the remaining air to the oor outlets and the defroster
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):Turn the right knob on the control panel to
this mode to direct air to the oor outlets, side window
outlets, and defroster. Recirculation is not available
in this mode.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is used
properly. There are two modes to clear fog or frost from
your windshield and side windows. Use the defog mode
to clear the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or frost
from the windshield more quickly. For best results, clear
all snow and ice from the windshield before defrosting.
/(Floor/Defog):Turn the right knob on the control
panel to this mode to direct the air to the windshield, the
side window outlets, and to the oor outlets. When
you select this mode, the system runs the air
conditioning system unless the outside temperature is
near freezing or below. Recirculation is not available
in this mode.
3-22

0(Defrost):Turn the right knob on the control panel
to this mode to direct most of the air to the windshield,
and the side window outlets. When you select this mode,
the system runs the air conditioning system unless
the outside temperature is near or below freezing.
Recirculation is not available in this mode.
Do not drive the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window when the key
is in the ignition and turned to ON.
=(Rear Defogger):Press the right knob on the
control panel to turn the rear window defogger on or off.
First press of this button will activate the rear window
defogger for 15 minutes and each subsequent activation
lasts 7 and one-half minutes.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Outlet Adjustment
Use the air outlets located in the center and on the side
of your instrument panel to direct the airow.
Your vehicle has air outlets that allow you to adjust the
direction and amount of airow inside the vehicle.
Move the louvers up or down to change the direction of
the airow. Use the thumbwheel under the outlets to
change the direction of the airow from left to right.
Operation Tips

Enable recirculation mode for maximum air
conditioning performance.
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to
move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are
going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts in
GM dealerships all across North America. They will be
ready and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to the
recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?

If No Steam Is Coming From Your
Engine
If you get an engine overheat warning but see or hear
no steam, the problem may not be too serious.
Sometimes the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades” under
Towing a Trailer on page 4-59.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL
while stopped. If it is safe to do so, pull off the
road, shift to PARK (P) or NEUTRAL and let the
engine idle.
2. Turn off the air conditioning.
3. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. Push down
the accelerator until the engine speed is about twice as
fast as normal idle speed for at least three minutes
while you are parked. If you still have the warning,
turn off the engine and get everyone out of the vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.
