Rear Power Sunshade
If your vehicle has a rear power sunshade, it helps
to reduce the amount of heat and light entering the
rear window.
The switch is located on
the overhead console.
The rear power sunshade is located in the rear
shelf. It only works while the ignition is on or while
the Retained Accessory Power (RAP) is active. See
Retained Accessory Power (RAP) on page 119.
To raise the power sunshade, press and release
the switch. To close the power sunshade, press and
release the switch again.

may get caught in the sunshade or be tossed
about in your vehicle.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put on it can make it impossible to steal.
Valet Lockout Switch
The valet lockout switch
is located inside the
glove box.
112

The theft-deterrent system will not arm if you lock
the doors with a key or use the manual door
lock. It activates only if you use a power door lock
with the door open or the RKE transmitter.
To avoid activating the alarm by accident:
Lock the vehicle with the door key or the
manual door lock after the doors are closed.
Always unlock a door with a key or use the
RKE transmitter system. Pressing the unlock
button on the RKE transmitter disables
the theft-deterrent system. Unlocking a door
any other way will activate the alarm when
a door or the trunk is opened.
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 unlock button on
the RKE transmitter system, or by starting the car
with a valid key.
Changes or modications made to this system by
other than an authorized service facility could
void authorization to use the theft system.
Testing the Alarm
1. From inside the vehicle, roll down the
window, then get out of the vehicle, keeping
the door open.
2. From outside of the vehicle, with the door
open, lock the vehicle using the power door
lock or the RKE system and close the
door. Wait 30 seconds until the security lamp
goes off.
3. Reach in and unlock the door using the
manual lock and open the door. The horn
will sound and the hazard lights will ash.
You can turn off the alarm by unlocking the driver’s
door with your key, using the unlock button on
the RKE transmitter or by starting the car with a
valid key.
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, seeFuses and Circuit
Breakers on page 452. If the fuse does not
need to be replaced, you may need to have your
vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.
114

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the ignition key is turned off:
Audio System
Audio Steering Wheel Controls
Power Windows
SunroofPower to these accessories will work up to
10 minutes or until the driver’s door is opened. For
an additional 10 minutes of power, close all the
doors and turn the key to RUN and then back
to OFF.
Starting the Engine
Place the transaxle in the proper gear.
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position – this is a safety feature. To
restart when you are already moving, use
NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Starting Procedure
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. Do not
race the engine immediately after starting it.

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:
The exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a
collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when
driving over high points on the road
or over road debris.
Repairs were not done correctly.
Your vehicle or the exhaust system
has 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 Variance
The mirror is set to zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if the
vehicle is driven outside zone eight. Under certain
circumstances, such as a long distance,
cross-country trip, it will be necessary to adjust the
compass variance.
Compass variance is the difference between
earth’s magnetic north and true geographic north.
If the mirror is not adjusted to account for zone
changes, the compass could give false readings.
To adjust for zone changes, do the following:
1. Find your current location and variance zone
number on the zone map that follows.
2. Press and hold the “auto highbeam” button
approximately six seconds until a zone number
appears in the display.
3. Once the zone number appears in the display,
press the “auto highbeam” button quickly until
you reach the correct zone number. Stop
pressing the button and the mirror will return to
normal operation. If C appears in the compass
window, the compass needs calibration. See
“Compass Calibration” listed previously.
133

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.
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
Your vehicle may have an automatic dimming
rearview mirror with a compass display. The mirror
also contains OnStar
®controls. For more
information seeOnStar®System on page 139.
The mirror includes an eight-point compass display
in the upper right corner of the mirror face.
When on, the compass automatically calibrates as
the vehicle is driven.
Mirror Operation
O
(On/Off):Press and hold the button, located
on the lower left side of the mirror face, for about
three seconds to turn the automatic dimming
feature on or off. The indicator light will illuminate
when this feature is active. The automatic dimming
feature is active each time the vehicle is started.
Compass Operation
Press the on/off button once to turn the compass
on or off.
When the ignition and the compass feature are
on, the compass will show two character boxes for
about two seconds. After two seconds, the
mirror will display the compass heading.
Compass Calibration
If after two seconds, the display does not show a
compass heading (for example, N for North),
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. If
the letter C should ever appear in the compass
window, the compass may need calibration.
The mirror can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the
display reads a direction.
The compass can be placed in calibration mode
manually by pressing and holding the on/off button
untilaCisshown in the compass display.

Compass Variance
The zone is set to 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 do the following:
1. Find the current location and variance
zone number on the following zone map.
2. Press and hold the on/off button until a zone
number appears in the display.
3. Once the zone number appears in the display,
press the on/off button quickly until the correct
zone number appears in the display. Stop
pressing the button and the mirror will return
to normal operation. If C appears in the
compass window, the compass may need
calibration. SeeCompass Calibration
listed previously.
