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 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:
1. Find your current location and variance zone number
on the following zone map.
2. Press and hold COMPASS (or the on/off button for
mirrors equipped with OnStar controls) until a zone
number appears in the display.
3. Once a zone number appears in the display, press
COMPASS (or the on/off button for mirrors equipped
with OnStar controls) quickly until the correct zone
number appears in the display. Stop pressing the
button and the mirror will return to normal operation.
If ªCº appears in the compass window, the compass
may need calibration. See ªCompass Calibrationº
explained previously.

2-54 Power Remote Control Mirrors
The controls for the power
remote mirror are located
on the driver's door armrest.
Move the L/R selector switch located beneath the
control pad to choose the left or right mirror.
To adjust the mirror, press the on the arrows located on
the control pad in the direction you want the mirror to go.
Leave the L/R selector switch in the center position, to
prevent unwanted mirror movement in case the control
pad is accidentally bumped while driving. Adjust each
outside mirror so that you can see a little of your vehicle,
and the area behind your vehicle.
Parallel Park Assist Mirror (If Equipped)
If you have the Memory Seat and Mirrors feature,
the passenger's outside rearview mirror includes a
tilt
-down feature that operates when the shift lever is
in REVERSE (R). This feature assists the driver with
improved rear obstacle detection. When the vehicle is
shifted out of REVERSE (R), the passenger mirror will
return to its original position after a five
-second delay.
This delay prevents movement of the mirror if multiple
gear transitions (REVERSE (R) to AUTOMATIC
OVERDRIVE (
) to REVERSE (R)) occur
during a parallel parking maneuver. This feature can
be programmed on or off through the personal choice
selection menu. See ªDIC Personal Choice Programmingº
in the Index for programming instructions.
Convex Outside 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.

2-55
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.
Automatic Dimming/Heated Outside
Rearview Mirror (If Equipped)
If you have this feature, the outside driver's mirror will
adjust for the glare of headlamps behind you. This
feature is controlled using the on and off settings on
the automatic electrochromic day/night rearview mirror.
See ªElectrochromic Day/Night Rearview Mirrorº
earlier in this section.
When you operate the rear window defogger, a defogger
also warms the heated driver's and passenger's outside
rearview mirrors to help clear them of ice and snow.
Storage Compartments
Glove Box
Use the door key to lock and unlock the glove box.
To open, lift the latch release on the left side of the
glove box door.
Front Storage Armrest
You may have a fold-down armrest between the front
seats that opens into a storage area. Press the buttons
on either side of the armrest to open the storage area for
cassette tapes, gloves, etc.
Front Center Console (Option)
Your vehicle may have a center console that opens to
two storage compartments. The front of the console has
two cupholders that can be unfolded for use. Flip the
center of the console forward to use the built
-in writing
surface on top of the lid.
You will also find an auxiliary power outlet located
inside the storage compartment and one on the lower
front edge of the console. These outlets can be used for
accessories requiring electrical power, such as a cellular
phone or fax machine. See ªAuxiliary Power Outletsº
in the Index.
The console also contains a coinholder as well as
storage for cassette tapes and compact discs.

2-57
Sun Visors
Illuminated Visor Vanity Mirrors
When you open the cover to either the passenger's
or driver's visor vanity mirror, the lamps will turn on.
The brightness of the lamp can be adjusted by sliding
the switch up or down.
Dual Sun Visors
Each sun visor has two parts, so that both the windshield
and door glass can be shaded at the same time. To use
the dual sun visors, flip the first visor down and turn it
toward the window. Then, flip the second visor down
toward the windshield.
Auxiliary Power Outlets
Your vehicle may have one or three power outlets
depending on the type of front seat you have. If your
vehicle has front bucket seats with a center console,
you will find one outlet inside the storage compartment
and the other on the lower front edge of the console.
(An extra power outlet can be found in the ashtray.)
The power outlets can be used to plug in electrical
equipment such as a cellular telephone or CB radio.
Follow the proper installation instructions that are
included with the equipment you install.Certain power accessory plugs may not be compatible
to the auxiliary power outlet and could result in blown
vehicle or adapter fuses. If you experience a problem
see your dealer for additional information on the power
accessory plugs.
The auxiliary power outlets will only operate when the
ignition key is in RUN and for 10 minutes after turning
the ignition off. If you would like the outlets to operate
regardless of ignition position, and for unlimited periods
of time, see ªEngine Compartment Bussed Electrical
Centerº in the Index or see your dealer.
NOTICE:
When using an auxiliary outlet:

The maximum load of any electrical
equipment should not exceed 15 amps.

Be sure to turn off any electrical
equipment when not in use. Leaving
electrical equipment on for extended
periods of time can drain your battery.

2-77
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transaxle,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.

2-78
If the light stops flashing and remains on steady,
see ªIf the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
See ªFuelº in the Index. Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start
-up, stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling on acceleration. (These conditions may
go away once the engine is warmed up.) This will be
detected by the system and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.

2-79
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still
does not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
Oil Pressure Light
If your vehicle has the
standard instrument panel
cluster, this light will come
on if there is a problem
with your vehicle's engine
oil pressure.
If your vehicle has the optional gage cluster, you
can read your oil pressure directly from the Driver
Information Center (DIC). See ªDIC Displays and
Controlsº in the Index.
The oil pressure light will come on briefly when you
turn your key to RUN. That's just a check to be sure
the light works. This is normal and doesn't show a
problem. If it doesn't come on and then go off,
be sure to have it fixed so it will be there to warn
you if there is a problem.
