Automatic Transmission Operation
If your vehicle is equipped with an automatic
transmission, it features an electronic shift position
indicator within the instrument panel cluster. This display
must be powered anytime the shift lever is capable of
being moved out of PARK (P). See
Fuses and Circuit
Breakers on page 5-110.
There are several different positions for your shift lever.
PARK (P):This position locks your rear wheels. It's the
best position to use when you start your engine because
your vehicle can't move easily. If your vehicle is equipped
with the Allison
žTransmission, use park for stationary
operation of the Power Takeoff (PTO) (if equipped).
{CAUTION:
It is 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.
CAUTION: (Continued)
CAUTION: (Continued)
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).
See ªShifting Into Park (P)º in the Index. If you
are pulling a trailer, see ªTowing a Trailerº in
the Index.
{CAUTION:
If you have four-wheel drive, your vehicle will be
free to roll Ð even if your shift lever is in PARK
(P) Ð if your transfer case is in NEUTRAL. So,
be sure the transfer case is in a drive gear,
two-wheel high (2H) or four-wheel high (4H) or
four-wheel low (4L) Ð not in NEUTRAL. See
ªShifting into Park (P)º in the index.
2-25

{CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to roll,
even if your shift lever is in PARK (P). So, be
sure the transfer case is in a drive gear Ð not
in NEUTRAL. Always set your parking brake.
Follow the proper steps to be sure your vehicle won't
move. See
Shifting Into Park (P) on page 2-46.
If you're pulling a trailer, see
Towing a Trailer on
page 4-68.
Mirrors
Manual Rearview Mirror
Pull the tab under the mirror toward you to reduce glare
from headlamps behind you after dark. Push the tab
away from you for normal daytime operation.
Automatic Dimming Rearview Mirror
with OnStar
ž, Compass and
Temperature Display
Your vehicle may have this feature. When on, an
electrochromic mirror automatically dims to the proper
level to minimize glare from lights behind you after dark.
The mirror also includes a duel display in the upper
right corner of the mirror face. The compass reading and
the outside temperature will both appear in the display
at the same time.
P(On/Off):This is the on/off button.
2-53

Temperature and Compass Display
Press the on/off button, located to the far left, brie¯y to
turn the comp/temp display on or off.
If the display reads CAL, you will need to calibrate the
compass. For more information on calibration, see
below.
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 ÉF, or ÉC
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.
Electrochromic Mirror Operation
The electrochromic (self dimming) mirror function is
turned on automatically each time the ignition is started.
To operate the electrochromic mirror do the following:
1. Make sure the green indicator light, located to
the left of the on/off button, is lit. If it's not, press
and hold the on/off button for approximately
six seconds until the green light comes on,
indicating that the mirror is in electrochromic (self
dimming) mode.
2. Turn off the electrochromic mirror function by
pressing and holding the on/off button for
approximately six seconds until the green indicator
light turns off.

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 you live 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, your 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 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 comp/temp display will return.
4. Calibrate the compass as described below.
2-55

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.
Passenger Air Bag Indicator
Your vehicle may be equipped with a passenger air bag
indicator, on the mirror glass, just above the buttons.
If your vehicle has this feature, the mirror will display the
word ON, or an air bag symbol in Canada, when the
passenger air bag is enabled. For more information, see
Passenger Sensing System on page 1-76.
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.
