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’ve 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
pulling it toward you. If you can, it means that the
shift lever wasn’t fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you don’t shift your
transaxle into PARK (P) properly, the weight of
the vehicle may put too much force on the parking pawl
in the transaxle. 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 2-30.
When you are ready to drive, move the shift lever out
of PARK (P)beforeyou 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 transaxle, so you
can pull the shift lever out of PARK (P).

Running Your Engine While You
Are 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 under
Engine Exhaust on page 2-34.
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 4-26.
{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
your 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 2-30.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-38.

Automatic Dimming Rearview
Mirror with Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass. Your vehicle’s mirror may
also contain OnStar
®controls. SeeOnStar®System on
page 2-41for more information.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face.
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.
Mirror Operation
MIRROR:Press this button to turn on the automatic
dimming feature. Press it again to turn off the automatic
dimming feature.
O(On/Off):For mirrors equipped with OnStar®
controls, press and hold this button for several seconds
to turn on the automatic dimming feature. Press and
hold it again to turn the automatic dimming feature off.
The green indicator light will come on when this
feature is active. The automatic dimming feature will be
active each time the vehicle is started.
Compass Operation
COMPASS:Press this button once to turn the compass
on or off.
O(On/Off):For mirrors equipped with OnStar®controls,
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 about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two 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. 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.
Mirrors equipped with OnStar
®controls can be placed
in calibration mode by pressing and holding the
on/off button untilaCisshown in the compass display.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
If your vehicle is equipped with the Head-Up Display
(HUD), an arrow will also appear in the display area
to indicate the direction of the turn or lane change.
SeeHead-Up Display (HUD) on page 3-18for more
information.
You may also have an arrow in the outside mirror that
ashes when the turn signal is used. SeeOutside Power
Mirrors on page 2-39for more information.To signal a lane change, just raise or lower the lever
until the arrow starts to ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
ash at twice the normal rate, this may indicate that a
signal bulb may be burned out and other drivers will not
see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check the fuse and check for burned-out
bulbs. SeeFuses and Circuit Breakers on page 5-99.
If you have a trailer towing option with added wiring for
the trailer lamps, the signal indicator will ash even if
a turn signal bulb is burned out. Check the front and
rear turn signal lamps regularly to make sure they
are working. You do not need to add a different asher.

be on. If your vehicle is
equipped with HUD, this
light will also appear in
the display area.
Flash-To-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are off.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are off or on low beam, your
high-beam headlamps will turn on. They will stay on as
long as you hold the lever toward you and the high-beam
indicator on the instrument panel cluster will come on.
Release the lever to turn the high-beam headlamps off.

Hold it there until the wipers start, then let go.
The wipers will stop after one cycle. If you want more
cycles, hold the band on MIST longer.
LO (Low Speed):Turn the band to LO for steady
wiping at a slow speed.
HI (High Speed):Turn the band to HI for steady wiping
at a high speed.
The wiper speed may be set for a long or short delay
between wipes. Turn the band to choose the delay time.
The closer to LO, the shorter the delay.
Heavy snow or ice can overload your wiper motor.
A circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Keep in mind that damaged wiper blades may prevent
you from seeing well enough to drive safely. To avoid
damage, be sure to clear ice and snow from the
wiper blades before using them. If your blades do
become damaged, get new blades or blade inserts.
