Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage
your vehicle.
In the notice area, we tell you about something that can
damage your vehicle. Many times, this damage would
not be covered by your warranty, and it could be costly.
But the notice will tell you what to do to help avoid
the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different
colors or in different words.
You'll also see warning labels on your vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle may be equipped with components and
labels that use symbols instead of text. Symbols,
used on your vehicle, are shown along with the text
describing the operation or information relating to a
specific component, control, message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator reference the following
topics in the Index:
ªEngine Compartment Overviewº
ªInstrument Panelº
ªComfort Controlsº
ªAudio Systemsº
Also see ªWarning Lights and Gagesº in the Index.

The switch is located on the instrument panel.
2WS: In this mode the vehicle will operate like any
other vehicle with two wheel steering. If you want to
use 2WS and your vehicle is not in this mode, press the
4 Wheel Steer button until the 2WS indicator, located to
the right of the 4 Wheel Steer button, lights up. If the
2WS indicator is flashing you will have to center the
steering wheel by turning it to the left or right.
4WS: In this mode all four wheels will help steer the
vehicle. If you want to use 4WS, and your vehicle is not
in this mode, press the 4 Wheel Steer button, until the
4WS indicator, located to the right of the 4 Wheel Steer
button, lights up. If the 4WS indicator is flashing you
will have to center the steering wheel by turning it to the
left or right.Slower Speed Mode (below 40 mph/64 kph)
At slower speeds the steering will operate in the lower
speed mode. This means the front and rear wheels will
turn in opposite directions. This helps the vehicle make
tighter turns, such as during parking, cornering and
turning into tight spaces.

The exterior lamp control has three positions:
(OFF): Turning the control to this position turns off
all lamps, except the Daytime Running Lamps (DRL).
It also puts the system into automatic headlamp mode.
(Parking Lamps): Turning the control to this
position turns on the parking lamps, together with
the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
Roof Marker Lamps (If Equipped)
(Headlamps): Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
You can switch your headlamps from high to low
-beam
by pulling on the turn signal/multifunction lever.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with a headlamp off delay,
which will keep the headlamps on for a short time after
the ignition is turned to OFF. For more information see
ªSecondary Information Centerº in the Index.
Your vehicle has a light sensor located on the top of
the instrument panel in the defroster grille. Be sure it
is not covered, or the system will be on whenever the
ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.

2-40
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems so that
driving under bridges or bright overhead street lights does
not affect the system. The DRL and automatic headlamp
system will only be affected when the light sensor sees a
change in lighting lasting longer than the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
You may be able to turn off your automatic headlamp
system. See ªDaytime Running Lamps (DRL)º later in
this section for more information.
As with any vehicle, you should turn on the regular
headlamps if you need them.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in OFF, LOCK or ACCESSORY. To disable the
chime, turn the thumbwheel all the way down. In the
automatic mode, the headlamps turn off once the
ignition key is in OFF.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on,
the exterior lamp control off,
the automatic transmission is not in PARK (P),
the light sensor determines it is daytime and
the parking brake is released.
When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.

2-43
Interior Lamps
Instrument Panel Brightness Control
This feature controls the brightness of the instrument
panel lights.
The thumbwheel for this feature is located next to the
exterior lamp control.
Turn the thumbwheel up to adjust the instrument panel
lights and return the radio display to full brightness
when the headlamps or parking lamps are on. To turn on
the dome lamps, with the vehicle doors closed, turn the
thumbwheel all the way up.
Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition. The lamps will
not come on if the DOME OVERRIDE button is
pressed in.
Illuminated Entry
Your vehicle is equipped with an illuminated entry feature.
When a door is opened, the dome lamps and puddle
lamps will come on if the DOME OVERRIDE button is
in the out position. If the DOME OVERRIDE button is
pressed in, the lamps will not come on.
Front Reading Lamps
Your vehicle has front
reading lamps located
in the overhead console.
Press the round button
located next to the lamp
to turn the lamp on.
The lamps can be adjusted
to point in the direction
you want them to go.
Press the button again to turn the lamp off.

2-45
Mirrors
Electrochromic Inside Rearview Mirror
with Compass, Temperature Display and
OnStar Controls
When on, an electrochromic mirror automatically dims
to the proper level to minimize glare from lights behind
you after dark.
The mirror also includes a dual 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.Temperature and Compass Display
Press the on/off button, located to the far left, briefly 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 switch between Fahrenheit and Celsius
do the following:
1. Press and hold the on/off button for four seconds
until either a flashing F, or C 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.

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.
Your vehicle also has a message center that works along
with the warning lights and gages. See ªMessage
Centerº in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind people to fasten
their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds, then it
will flash for several more.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
