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 280.
{CAUTION:
It can be dangerous to get out of your
vehicle if the automatic transmission 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 it is on fairly
level ground, always set the parking brake
and move the automatic transmission
shift lever to PARK (P), or the manual
transmission shift lever to NEUTRAL.

{CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to
roll, even if your automatic transmission
shift lever is in PARK (P). So, be sure the
transfer case is in a drive gear — not in
NEUTRAL. Always set your parking brake.
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P)
(Automatic Transmission) on page 132.
If you are pulling a trailer, seeTowing a Trailer
on page 300.
Mirrors
Manual Rearview Mirror
While sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind
your vehicle. Grip the mirror in the center to move
it up or down and side to side. The control at
the bottom of the mirror is the day/night feature
that allows adjustment to the mirror so that
the glare of headlamps from behind is reduced.
Push the control for daytime use; pull it for
night use.
Manual Rearview Mirror with
OnStar
®
Mirror Operation
Your vehicle may have a manual rearview mirror
with the OnStar®System. You can adjust the mirror
for day or night driving. Press the tab forward for
day driving. Pull the tab back for night driving.

There are also three OnStar®buttons located at
the bottom of the mirror. See your dealer for more
information on the system and how to subscribe
to OnStar
®. SeeOnStar®System on page 146
for more information about the services OnStar®
provides.
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
housing.
Automatic Dimming Rearview Mirror
with OnStar
®, Compass and
Temperature Display
Your vehicle may have this feature. When on,
the automatic dimming mirror dims to the proper
level to minimize glare from lights behind you
after dark.
The mirror has a dual display in the upper right
corner of the mirror face that shows the compass
reading and the outside temperature.Control buttons for the OnStar
®system are at
the bottom of the mirror. SeeOnStar®System
on page 146for more information about the
services OnStar
®provides.
P(On/Off):This is the on/off button.
Temperature and Compass Display
Press the on/off button, located to the far
left, brie y to turn the compass/temperature
display on or off.
If the display reads CAL, the compass needs
to be calibrated. For more information, see
“Compass Calibration” following.
To adjust between Fahrenheit and Celsius,
do the following:
1. Press and hold the on/off button for
approximately four seconds until either a
ashing F or C appears.
2. Press the button again to change the display
to the desired unit of measurement. After
approximately four seconds of inactivity,
the new unit will be locked in and the
compass/temperature display will return.

If an abnormal temperature reading is displayed
for an extended period of time, see your
dealer. Under certain circumstances, a delay
in updating the temperature is normal.
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 lit. If it is
not, press and hold the on/off button for
approximately six seconds 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 and holding the on/off button for
approximately six seconds, until the green
indicator light turns off.
Compass Calibration
The compass may need calibration if one of the
following occurs:
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 the on/off button for approximately
12 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.

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 the
vehicle is 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, the 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 untilaZand
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 compass/temperature display will return.

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 Compass and Temperature
Display
Your vehicle may have this mirror. When on, an
automatic dimming mirror will dim to the proper
level to minimize glare from lights behind you
after dark.
The mirror also includes a dual display in the
upper right corner of the mirror with the compass
reading and the outside temperature.
Yb:Brie y press this button to turn the display
on or off.
Temperature Display
The temperature can be displayed by pressing the
compass/temperature button. Pressing the
compass/temperature button once brie y, will
toggle the display reading on and off. To alternate
the temperature reading between Fahrenheit and
Celsius, press and hold the compass/temperature
button for approximately three seconds until the
display blinks F and C. After approximately ve
seconds of inactivity, the display will stop blinking
and display the last selection made.
If an abnormal reading is displayed, see your
dealer.

Automatic Dimming Mirror Operation
O
:Press this button to turn the automatic
dimming feature on or off. The indicator light to
the left of the button will turn on to indicate when
the feature is on. Once the mirror is turned off,
it will remain off until it is turned back on, or until
the vehicle is restarted.
Compass Operation
Press the compass/temperature button once
brie y to turn the display on or off.
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 compass/temperature button for
approximately nine 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.
