Running the Engine While Parked
It is better not to park with the engine running. But
if you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 136.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is
at the highest setting. One place this
can happen is a garage. Exhaust — with
CO — can come in easily. NEVER park
in a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 317.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your vehicle when the engine is running
unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
always set the parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 132.
If you are parking on a hill and if you are pulling
a trailer, also seeTowing a Trailer on page 333.

Mirrors
Manual Rearview Mirror
This mirror can be adjusted two ways. First, to
adjust the angle of the mirror, move the mirror
to a position that allows you to see out of the
back window. To adjust the height of the mirror,
adjust the support that connects the mirror to
the windshield.
To reduce glare from lights behind you, move
the lever toward you to the night position.
Manual Rearview Mirror with
OnStar
®
If your vehicle has this feature, this mirror has a
knob located at the bottom of the mirror. It is used
to change the mirror from day to night position.
To reduce glare from headlamps behind you while
driving at night, rotate the knob clockwise. For
daytime driving, turn the knob counterclockwise.
There are also three OnStar
®buttons located
at the bottom of the mirror face. See your dealer
for more information on the system and how
to subscribe to OnStar
®. SeeOnStar®System

Automatic Dimming Rearview Mirror
with OnStar
®and Compass
Your vehicle may have an automatic dimming
rearview mirror with a compass and OnStar®
controls. For more information about OnStar®,
seeOnStar®System on page 144.
The automatic dimming feature turns on each time
the vehicle is started. To turn automatic dimming
off or on, press the left button below the mirror.
A green indicator light will be on when automatic
dimming is on.
There are also three OnStar
®buttons located at
the bottom of the mirror. See your dealer/retailer
for more information on the system and how
to subscribe to OnStar
®. SeeOnStar®System
on page 144for more information about the
service OnStar
®provides.
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
a few seconds. After a few seconds, the mirror
will display the current compass direction.
Compass Calibration
If after a few seconds the display does not show
a compass direction, (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, note pad
holder, or similar object. If the letter C appears
in the compass window, the compass may need
to be reset or calibrated.
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.

Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic north.
If the mirror is not adjusted for compass
variance, the compass could give false readings.
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 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.
To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the zone map that follows.
2. Press and hold the on/off button until a
zone number appears on the display.
3. Once the zone number appears on the
display, press the on/off button quickly
until you reach the correct zone number.
If C appears in the compass window,
the compass may need calibration. See
“Compass Calibration” listed previously.

Automatic Dimming Rearview Mirror
with Compass
Your vehicle may have an automatic dimming
rearview mirror with a compass. This feature
enables the mirror to sense nighttime glare
from vehicle headlamps from behind and
automatically dim to reduce the glare to a
safe level. The automatic dimming feature
turns on each time the vehicle is started.
O(On/Off):This is the on/off button for the
automatic dimming feature.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned
on automatically each time the ignition is started.
To operate the automatic dimming mirror, do
the following:
1. Make sure the green indicator light, located
to the left of the on/off button, is on. If it’s
not, press the on/off button until the green
light comes on, indicating that the mirror is
in automatic dimming mode.2. Turn off the automatic dimming mirror function
by pressing the on/off button until the green
indicator light turns off.
Compass Operation
Y
:This is the on/off button for the compass
feature.
Press this 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 a few seconds. After a few seconds, the mirror
will display the current compass direction.
Compass Calibration
If after a few seconds the display does not show
a compass direction, (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, note pad
holder, or similar object. If the letter C or CAL
appears in the compass window, the compass
may need to be reset or calibrated.
141

To calibrate the compass, do the following:
Make sure CAL is displayed in the display.
If CAL is not displayed, press and hold the
compass button until CAL is displayed.
Drive the vehicle in circles at 5 mph (8 km/h)
or less until the display reads a direction.
Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic north.
If the mirror is not adjusted for compass
variance, the compass could give false readings.
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 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.
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 compass button until a
Z and a zone number appears on the display.
3. Once the zone number appears on the
display, press the compass button quickly
until you reach the correct zone number.
If C or CAL appears in the compass window,
the compass may need calibration. See
“Compass Calibration” listed previously.

Outside Power Mirrors
The controls for the
outside power mirrors
are located on the
driver’s door armrest.
Use the selector switch located below the four-way
control panel to choose either the left or right
outside mirror. Then press any of the four arrows
located on the control pad to move each mirror
in the desired direction.
Adjust each mirror so you can see the side of your
vehicle and the area beside and behind your
vehicle.
Outside Power Heated Mirrors
If the vehicle has this feature, when the rear
window defogger is turned on, the heated driver’s
and passenger’s outside power mirrors are
warmed to help clear them of ice, snow and
condensation. See “Rear Window Defogger” under
Climate Control System on page 188for more
information. Also seeOutside Power Mirrors
on page 143for mirror operation.

Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like
other vehicles) look farther away than
they really are. If you cut too sharply
into the right lane, you could hit a vehicle
on your right. Check your inside mirror
or glance over your shoulder before
changing lanes.
The passenger side mirror is convex. A convex
mirror’s surface is curved so more can be
seen from the driver’s seat. It also makes things,
like other vehicles, look farther away than they
really are.
