Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever away from PARK (P) without rst pressing
the button on the console shift lever. If you can, it
means that the shift lever was not fully locked into
PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in the
transmission. You may nd it difficult to pull the shift lever
out of PARK (P). This is called “torque lock.” To prevent
torque lock, set the parking brake and then shift into
PARK (P) properly before you leave the driver’s seat. To
nd out how, seeShifting Into Park (P) on page 2-26.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. SeeAutomatic Transmission
Operation on page 2-22.

rearview 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 day/night control, located at
the bottom of the mirror, adjusts the mirror to reduce
headlamp glare from behind during evening or dark
conditions. Turn the control clockwise for night
use; return it to the center for daytime use.

®
The vehicle may have a rearview mirror with the
OnStar®system.
Control buttons for the OnStar
®system are at the
bottom of the mirror. See your GM dealer for more
information on the OnStar
®system and how to
subscribe to OnStar®. Also, seeOnStar®System on
page 2-40for more information about the services

Manual Rearview Mirror with
Compass and Temperature
The vehicle may have a manual rearview mirror with an
eight-point compass and temperature display located
in the upper right.
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.

Temperature and Compass Display
O
(On/Off):Press this button to turn the compass and
temperature display on or off. The compass display,
can show a maximum of two characters. For example,
NE is displayed for north-east.When the ignition and the compass/temperature feature
are on, character boxes will appear for about
two seconds. After two seconds, the mirror will display
the direction the vehicle is facing and the outside
temperature.
To set the temperature in Fahrenheit or Celsius, do the
following:
1. Press and hold the on/off button until either a
ashing F or C appears.
2. Press the button again to change the display to the
desired unit of measurement. After about four
seconds of inactivity, the new unit will be locked in
and the compass/temperature display will return.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two 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, 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.
