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 off. In addition, you have to fully
apply your regular brake before you can shift from
PARK (P) when the ignition is on. SeeAutomatic
Transmission Operation on page 2-26.
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way
into PARK (P) and release the shift lever button as you
maintain brake application. Then press the shift lever
button and move the shift lever into the gear you wish.
If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Put the vehicle in accessory power mode.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and then shift to the drive gear
you want.
5. Have your vehicle inspected by your dealer as soon
as possible.
Parking Your Vehicle
(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, you can turn the ignition
off and release the clutch.

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:
Your exhaust system sounds strange or
different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a collision.
Your vehicle was damaged when driving
over high points on the road or over road
debris.
Repairs were not done correctly.
Your vehicle or 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 under
Engine Exhaust on page 2-36.
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. See
Winter Driving on page 4-28.
{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) (Automatic
Transmission) on page 2-33.

Mirrors
Manual Rearview Mirror
When you are 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 day/night control, located at
the bottom of the mirror, lessens glare from the
headlamps behind your vehicle when in the night
position. Turn the control to the right for the night
position and to the left for the day position.
Two buttons under the rearview mirror control map
lamps. Push each button to turn each map lamp on
or off.
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
The vehicle may have an automatic dimming rearview
mirror with OnStar®, a compass and map lamps.
Three OnStar®buttons are at the bottom of the mirror.
SeeOnStar®System on page 2-45for more
information the services OnStar®provides.
Mirror Operation
The mirror automatically changes to reduce glare from
headlamps behind you. A time delay feature prevents
rapid changing from the day to night positions while
driving under lights and through traffic.
P(On/Off):The automatic dimming feature is
automatically activated when the vehicle is started.
The automatic dimming feature is turned on or off by
pressing this button located on the lower part of
the mirror. Press and hold the button for up to
three seconds to turn this feature on or off.
T(Indicator Light):This light will turn on when the
automatic dimming feature is active.

Map Lamps
The mirror has map lamps located at the bottom of the
mirror. To manually turn the lamps on or off, press the
button next to each lamp.
Compass Operation
The mirror has an eight-point compass display in the
bottom of the mirror face.
When the ignition and the compass feature are on, the
compass will show two character boxes for approximately
two seconds. After two seconds, the mirror will display
the current compass heading. For example, NE is
displayed for north-east.
Compass Calibration
If after two seconds the display does not show a
compass heading, 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 needs calibration.
The mirror compass can be calibrated by driving
the vehicle in circles at 5 mph (8 km/h) or less until
the display reads a direction.
The compass can be placed in calibration mode by
pressing and holding the left map light button until
a C appears on the compass display.

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, your 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 you live 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 map light 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. Stop pressing the button and the
mirror will return to normal operation. If C appears
in the compass window, the compass may need
calibration. See “Compass Calibration” listed
previously.

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
If the vehicle has this feature, an automatic dimming
mirror automatically dims to the proper level to minimize
glare at night from lights behind your vehicle.
The mirror also includes a compass display in the upper
right corner of the mirror face.
P(On/Off):This is the on/off button.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned on each
time the ignition is started. A light near the on/off button
will come on to indicate the automatic dimming is on.
Press the on/off button for about six seconds to
manually turn the automatic dimming function on or off.
Compass Display
Press the on/off button, located to the far left, brie y to
turn the compass display on or off.
If the display reads CAL, the compass needs to be
calibrated. For more information, see “Compass
Calibration” later in this section.
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, please consult your dealer.
Under certain circumstances, a delay in updating
the temperature is normal.

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 mirror’s 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 you live
outside of zone eight. Under certain circumstances, as
during a long distance cross-country trip, it will also be
necessary to adjust for 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 on/off button until a Z and 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.
4. Calibrate the compass as described next.
