Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't 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 can't 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 weren't done correctly.
·Your vehicle or exhaust system had 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 Your Engine While You
Are Parked
It's 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
ªEngine Exhaust.º
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 Ð with CO Ð can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
ªWinter Drivingº in the Index.
{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. Don't leave your vehicle when the engine
is running unless you have to. If you've left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle won't move, even when
you're 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 won't
move. See
Shifting Into Park (P) on page 2-28.
If you're pulling a trailer, see
Towing a Trailer on
page 4-54.

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
ž, Compass and
Temperature Display
Your vehicle may have this feature. When on, the 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.
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.

Self Dimming Mirror Operation
The self dimming mirror function is turned on
automatically each time the ignition is started. To
operate the mirror, do the following:
1. Make sure the green indicator light, 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 self dimming mode.
2. Turn off the self dimming 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.
2-34
Page 133 of 486

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 then 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 1-85.
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.

Outside Power Mirrors
The controls are located
on the driver's door
armrest.
Move the upper selector switch to the left or right to
choose the mirror you want to adjust; then press
the dots located on the four-way control pad to adjust
the mirror.
To fold or unfold the mirrors, move the selector switch,
located above the mirror control, to the middle
position. The mirror control will illuminate. Press the
right or left side of the mirror control to fold or unfold the
mirrors. You may notice the mirror glass adjust as the
mirrors fold in; this is normal. The mirror glass will
reposition itself once the mirrors are unfolded.If the mirrors are accidently manually folded in or you
notice that the mirrors will not stay in the unfolded
position, unfold and fold them at least twice using the
mirror controls. Do not unfold them manually. The
mirrors may not stay in place otherwise.
The mirrors may also include a memory function which
works in conjunction with the memory seats. See
Memory Seat on page 2-50for more information.
Outside Convex Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.

Outside Heated Mirrors
Your vehicle may have this feature.
When you press this
button, a defogger warms
the heated driver's and
passenger's outside
rearview mirrors to help
clear them of ice,
snow and condensation.
If your vehicle has a rear window defogger, it will also

Defoggerº under
Automatic Climate Control System
on page 3-24for more information.
Outside Automatic Dimming Mirror
with Curb View Assist
Your vehicle may have this feature.
The driver's outside mirror will adjust for the glare of the
headlamps behind you. See
Automatic Dimming
Rearview Mirror with OnStarž, Compass and
Temperature Display on page 2-33.
Your vehicle's mirrors will also be capable of performing
the curb view assist mirror function. This feature will
cause the passenger's and/or driver's mirror to tilt to a
preselected position when the vehicle is in
REVERSE (R). This feature may be useful in allowing
you to view the curb when you are parallel parking.
When the vehicle is shifted out of REVERSE (R) and a
short delay has occurred, the passenger's and/or
driver's mirror will return to its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory as
the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. See
Driver Information Center (DIC)
on page 3-51for more information.
