Ignition Positions
Use the key to turn the ignition switch to
four different positions.
A (Lock):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will only
be able to remove the key when the ignition is turned
to LOCK.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.B (Accessory):This position lets you use things like the
radio and the windshield wipers when the engine is off.
Notice:Lengthy operation of features such as the
radio in the accessory ignition position may drain the
battery and prevent your vehicle from starting. Do not
operate your vehicle in the accessory ignition
position for a long period of time.
C (Run):This is the position for driving.
D (Start):This position starts the engine.
Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features of
your vehicle to continue to work up to 20 minutes
after the ignition key is turned to LOCK.
Your radio, power windows, sunroof (option) and
overhead console will work when the ignition key is in
RUN or ACCESSORY. Once the key is turned from
RUN to LOCK, these features will continue to work for
up to 20 minutes or until a door is opened.

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 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 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 2-34.
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 4-39.

Compass Display
O
(On/Off):Press this button to turn the compass on
or off. The compass display, can show a maximum
of two characters. For example, NE is displayed
for north-east.
When the ignition and the compass/temperature feature
are on, character boxes will appear for about
two seconds. After two seconds, the mirror will display
the direction the vehicle is facing.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass 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. If
the letter C should ever appear in the compass window,
the compass may need calibration.
Press and hold the on/off button for nine seconds to
activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display shows
a direction.

Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. 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 you live outside zone eight. Under
certain conditions, such as during a long-distance,
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account for compass
variance, the compass could give false readings. To
adjust for compass variance do the following:
1. Find the current location and variance zone number
on the following zone map.
2. Press and hold the on/off button until a zone
number appears in the display.
3. Once a zone number appears in the display, press
the on/off button quickly until the correct zone
number appears in the display. If C appears in the
compass window, the compass may need
calibration. See “Compass Calibration”
explained previously.

Manual Rearview Mirror with
OnStar
®and Compass
The vehicle may have a manual rearview mirror with
OnStar®and an eight-point compass display located in
the upper right.
Control buttons for the OnStar
®system are at the
bottom of the mirror. See your GM dealer for more
information on the OnStar
®system. Also, seeOnStar®
System on page 2-47for more information about the
services OnStar®provides.
Mirror Operation
While sitting in a comfortable position, adjust the
rearview mirror so you can see clearly behind your
vehicle. Grip it in the center and move it up or down and
side to side. The day/night control, located at the
bottom of the mirror, adjusts the mirror to reduce
headlamp glare from behind during evening or dark
conditions. Push the control for daytime use; pull it for
night use.
