Electrochromic Inside Rearview Mirror
with Compass (Option)
Your vehicle may have an electrochromic inside
rearview mirror.
When on, the mirror automatically dims to the proper
level
to minimize glare from lights behind you after dark.
The mirror also 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.
To use the electrochromic mirror only, move the switch
at the bottom
of the mirror to the M position. To use the
electrochromic mirror
as well as the compass. move the
switch to the
C/M position. To turn both features off,
move the switch to the
OFF position. When
the ignition is on and the mirror switch is
in the
CIM position, the compass display'will show two
character boxes for approximately two seconds. If, after
two seconds, the display does
not show a compass
heading
(N for North, for example), there may be a
strong magnetic field interfering with the compass. Such
interference may include magnetic antenna mounts,
a
magnetic note pad holder, or a similar magnetic item. If
removing these items does not correct the condition, see
your
GM dealer for assistance.
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
liquid cleaner to enter the mirror housing.
Compass Varia~ 3
Under certain circumstances, as during a long distance
cross-country trip,
it will be necessary to adjust the
compass
to compensate 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
hlse readings.

Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help
you
locate them.
Warning lights and gages can signal
that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save
you or
others from injury.
Warning lights come on when there may be
or is a
problem with one of your vehicle’s functions.
As you
will see in the details on the next few pages, some
warning lights come
on briefly when you start the
engine just
to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one
of your vehicle’s functions. Often gages and
warning lights work together
to let you know when
there’s a problem with your vehicle. When
one of the warning lights comes on and stays on
when
you are driving, or when one of the gages shows
there may be a problem, check the section that
tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.

It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210°F

load or going up hills, it is normal for the temperature to
fluctuate and approach the 260°F ( 125 “C) mark. If the
gage reaches the 260°F
(I 25 “C) mark, it indicates that
the cooling system is working beyond its capacity.

Malfunction Indicator Lamp (Service
- ;ine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission SERVICE
ENGINE
SOON
control systems.
This system
is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. (In Canada,
OBD TI is replaced by
Enhanced Diagnostics.) The
SERVICE ENGINE SOON
light comes on to indicate that there is a problem and
service
is required. Malfunctions often will be indicated
by the system before any problem
is apparent, which
may prevent more serious damage to your vehicle. This
system is
also designed to assist your service technician
in correctly diagnosing any malfunction.
I 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.
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:
0 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
is required.
0 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 If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
0 If towing a trailer, reduce the amount of cargo being
hauled
as soon as it is possible.
If the light stops flashing and remains
on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off, wait at least
10 seconds and restart the engine.
If the light remains
on steady, see “If the Light Is On
Steady” following.
If the light is still flashing follow the
previous steps, and drive the vehicle
to your dealer or
qualified service center for service.
You may be able to correct the emission system
malfunction by considering the following:
Did you just put fuel
into your vehicle?
If so7 reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This will
allow fuel to evaporate into
the atmosphere. A few
driving trips 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.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make
sure to install the fuel cap properly. it
will take a few driving trips to turn the light off.
