Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift
lock control system which locks the shift lever
in PARK (P) when the ignition is in the LOCK
position. In addition, you have to fully apply the
regular brakes before you can shift from PARK (P)
when the ignition is in ON. SeeAutomatic
Transmission Operation on page 124.
If you cannot shift out of PARK (P), ease pressure
on the shift lever by pushing the shift lever all
the way into PARK (P) as you maintain brake
application. Then, move the shift lever into
the gear you want.
If you ever hold the brake pedal down but still
cannot shift out of PARK (P), try this:
1. Turn the key to ACC. There is no shift
interlock in this key position.
2. Apply and hold the brake until the end of
Step 4.3. Shift the transmission to NEUTRAL (N).
4. Start the vehicle and then shift to the gear
you want.
5. Have the system xed as soon as you can.
Parking Your Vehicle
(Manual Transmission)
Your vehicle has a manual transmission.
Before you get out of your vehicle, move the
shift lever into REVERSE (R), and rmly apply
the parking brake. Once the shift lever has
been placed into REVERSE (R) with the clutch
pedal pressed in, turn the ignition key to LOCK,
remove the key and release the clutch.
If you are parking on a hill, or if your vehicle is
pulling a trailer, seeTowing a Trailer on page 306.

Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.

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 modi ed 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.

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 139.
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 286.
{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.
140
Page 141 of 496
{CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to
roll, even if the automatic transmission
shift lever is in PARK (P). So, be sure the
transfer case is in a drive gear — not in
NEUTRAL. Always set the parking brake.
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P)
(Automatic Transmission) on page 135.
If you are pulling a trailer, seeTowing a Trailer
on page 306.
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 149
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 149for 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.
142
Page 143 of 496

If the display reads CAL, the compass needs
to be calibrated. For more information, see
“Compass Calibration” following.
To adjust between Fahrenheit and Celsius:
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/retailer. Under certain circumstances, a
delay in updating the temperature is normal.
Automatic Dimming Mirror Operation
The automatic dimming mirror comes on each time
the ignition is turned to start. To turn the automatic
dimming feature off or back on, press the on/off
button. The indicator light on the mirror is lit when
the automatic dimming feature is on.
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:
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.
