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.
Your vehicle was damaged when driving
over high points on the road or over road
debris.
CAUTION: (Continued) CAUTION: (Continued)
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 under
Engine Exhaust on page 2-39 .
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 4-30 . { 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 the
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. See Shifting Into PARK (P) on page 2-36 .
If you are pulling a trailer, see Towing a Trailer on
page 4-44 .

Mirrors Automatic Dimming Rearview Mirror
with Intellibeam ®
, OnStar ®
,
Compass, and Temperature Display Your vehicle may have an automatic dimming rearview
mirror with Intellibeam ®
, OnStar ®
, compass and
temperature display. For more information on OnStar ®
,
see OnStar ®
System on page 2-50 . For more
information on Intellibeam ®
, see “Intellibeam ®
Intelligent
High-Beam Headlamp Control System” under Exterior
Lamps on page 3-16 .
The mirror includes an eight-point compass display in
the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle is
driven. Outside temperature is also shown in the display.
Automatic Dimming Your vehicle has an inside automatic dimming rearview
mirror. The automatic dimming feature is activated
whenever the vehicle is turned on and dims only during
nighttime driving. Compass Operation AUTO
3 : Press and hold the “auto highbeam” button
for about three seconds to turn the
compass/temperature display on or off.
When the ignition and the display features are on, the
display will show two character boxes for about two
seconds. After two seconds, the mirror will display the
compass heading and temperature.
Compass Calibration If after two seconds the display does not show the
correct direction, (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 can be placed in calibration mode
manually by pressing and holding the “auto highbeam”
button for about nine seconds until CAL is shown in
the compass display.
The mirror can then be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads the correct direction.

Compass Variance The mirror is set to zone eight upon leaving the factory.
It will be necessary to adjust the compass to
compensate for compass variance if the vehicle is
driven outside zone eight. Under certain circumstances,
such as a long distance, cross-country trip, it will be
necessary to adjust the compass variance.
Compass variance is the difference between earth’s
magnetic north and true geographic north. If the mirror
is not adjusted to account for zone changes, the
compass could give false readings.
To adjust for zone changes:
1. Find your current location and variance zone
number on the zone map that follows.
2. Press and hold the “auto highbeam” button about
six seconds until a zone number appears in the
display.
3. Once the zone number appears in the display,
press the “auto highbeam” 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 needs calibration. See “Compass
Calibration” listed previously.
