At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or
if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page

Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set
off the alarm if the system
has been armed.
If you set off the alarm by accident, unlock any door
with the key. You can also turn
off the alarm by pressing
UNLOCK on the remote keyless entry transmitter or
by placing the key in the ignition and turning it to
START.
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 and the headlamps do not
flash, you may have the feature turned
off. See DIC
Operation and Displays on page 3-43 for more
information.
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 light 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 light 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
Fuses and Circuit Breakers on page 5-95.) See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See
Roadside Assistance Program on page 7-5
under Customer Assistance Information.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver’s side of the engine
compartment, near the power steering fluid
reservoir. If you have a diesel engine, refer to
diesel supplement for location.
3. Plug it into a normal, grounded 11 0-volt AC outlet.
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a fire. You could
be seriously
injured. Plug the cord into a properly grounded
three-prong
11 0-volt AC outlet. If the cord
won’t reach, use a heavy-duty three-prong
extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug ana
store the cord as it was before to keep it away
from moving engine parts.
If you don’t, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
Your vehicle is equipped with an automatic transmission
that features an electronic shift position indicator
located within the instrument panel cluster. This display
is powered anytime the shift lever
is capable of being
moved out
of PARK (P). See Fuses and Circuit Breakers
on page
5-95.
There are several different positions for your shift lever.
PARK
(P): This position locks your wheels. It’s the
best position to use when you start your engine because
your vehicle can’t move easily.

Mirrors
Automatic Dimming Rearview Mirror
with Onstar@, Compass and
Temperature Display
Your vehicle may have this feature. When on, an
electrochromic mirror automatically dims to the proper
level to minimize glare from lights behind you after dark.
The mirror also includes a duel display in the upper
right corner of the mirror face. The compass reading and
the outside temperature will both appear in the display
at the same time.
cl) (On/Off): This is the on/off button.
Temperature and Compass Display
Press the on/off button, located to the far left, briefly to
turn the comp/temp display on or off.
If the display reads CAL, you will need to calibrate the
compass. For more information on calibration, see below.
To adjust between Fahrenheit and Celsius do the
following:
1. Press and hold the on/off button for approximately
four seconds until either a flashing
OF, or "C
appears.
desired unit of measurement. After approximately
four seconds of inactivity, the new unit will be locked

Electrochromic Mirror Operation
The electrochromic (self dimming) mirror function is
turned on automatically each time the ignition is started.
To operate the electrochromic mirror do the following:
1. Make sure the green indicator light, located to the left
of the on/off button, is lit.
If it's not, press and hold the
on/off button for approximately six seconds until the
green light comes on, indicating that the mirror is in
electrochromic (self dimming) mode.
2. Turn off the electrochromic mirror function by
pressing and holding the on/off button for
approximately six seconds until the green indicator
light turns off.

Compass Variance
The mirror 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 of 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 do the following:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the on/off button until a Z and a
zone number appears in the display. The compass
is now in zone mode.
3. Keep pressing the on/off button until the desired
zone number appears in the display. Release the
button. After approximately four seconds of
inactivity, the new zone number will be locked in
and the comp/temp display will return.
4. Calibrate the compass as described below.
2-29

Compass Calibration
The compass may need calibration if one of the
following occurs:
After approximately five seconds, the display does
not show a compass heading
(N 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, CAL must be displayed in the
mirror compass windows.
If CAL is not displayed, push
the
on/off button for approximately 12 seconds or
until CAL is displayed.
The compass can be calibrated in one of two ways:
Drive the vehicle in circles at 5 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.
Passenger Air Bag Indicator
Your vehicle may be equipped with a passenger air bag
indicator, on the mirror glass, just above the buttons.
If your vehicle has this feature, the mirror will display the
word
ON, or an air bag symbol in Canada, when the
passenger air bag is engaged. For more information,
see
Passenger Sensing System on page 1-68.
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
If your vehicle is equipped
with outside power mirrors,
the controls are located
on the driver’s door
armrest.
Move the selector switch located above the control pad
to the left or right to choose the mirror you want to
adjust, then press the dots located on the four-way
control pad to adjust the mirror.
The mirrors include ground illumination lamps (puddle
lamps) in the base of the mirror. For more information on
these lamps, see
Puddle Lamps under Exterior Lamps
on page 3-1
1.
The mirrors also include a memory function which works
in conjunction with the memory seats. See “Memory
Seats” in the Index for more information.
Outside Power Foldaway Mirrors
If your vehicle is equipped with outside power foldaway
mirrors the mirrors can be folded in toward the body
of the vehicle.
To fold
in the mirrors, move the upper selector switch,
located above the mirror control, to the middle position.
Press the right side of the mirror control to fold the
mirrors toward the body
of the vehicle. The mirror glass
on one or both sides of the vehicle may automatically
adjust before the mirror folds inward. When the
mirror glass or mirror starts moving, you can release the
mirror control.
To return the mirrors and the mirror glass to their
normal position press the left side of the mirror control.
If the mirrors are manually folded, use the power
mirror control to return it to it’s original position.
Outside Automatic Dimming Mirror
The driver’s outside mirror will adjust for the glare of any
headlamps behind you. This feature is controlled by
the on and
off settings on the electrochromic mirror. See
“Electrochromic Mirror Operation” under
Automatic
