Vehicle Damage Warnings
Also, in this book you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will 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 has 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 specic component, control,
message, gage or indicator.
If you need help guring out a specic name of a
component, gage or indicator, reference the following

Exterior Lamps
The control on the driver’s
side of your instrument
panel operates the exterior
lamps. Turn the control
clockwise to operate
the lamps.
The exterior lamp control has four positions:
Ø (Defeat):Turn and release the control to this position
to turn off the DRLs. To turn them back on, turn and
release the control to this position again. Shutting
the vehicle off and restarting it will also reactivate
the DRLs.
This feature is not available on vehicles rst sold in
Canada.
i(Daytime Running Lamps (DRL)):Turning the
control to this position selects the DRLs. When the
vehicle is shifted out of PARK (P), the instrument panel
lamps will illuminate and the DRLs will turn on, unless
defeated. When the DRLs are active, the DRL indicator
will illuminate.
;(Parking Lamps):Turn the control to this position
to turn on the parking lamps, together with the
following:
Instrument Panel Lights
Daytime Running Lamps
Sidemarker Lamps
Taillamps
License Plate Lamps
Ashtray Lamp
If the DRLs are active when the control is turned to this
position, the DRLs will turn off.
For vehicles rst sold in Canada, the DRLs will remain
active along with the lamps mentioned above.

Dome Lamp Override
You can use the dome
override button, located
below the exterior
lamp control, to set the
dome lamps to come
on automatically while a
door is opened, or to
remain off.
To turn the automatic operation of the lamps off, press
the button. The dome lamps will remain off while a
door is open. To return the lamps to automatic
operation, press the button again.
While pressed in, this will override the illuminated entry
feature unless you use your keyless entry transmitter
to unlock the vehicle.
Exit Lighting
With exit lighting, the interior lamps will come on for a
period of forty seconds when you remove the key
from the ignition. The lights will not come on if the dome
override button is pressed in.
Entry Lighting
Your vehicle is equipped with an illuminated entry
feature.
When a door is opened, the dome 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. When the door is closed, the interior lamps
will remain on for a period of fteen seconds or until
the vehicle is started.
Reading Lamps
To turn on the reading lamps, press the button
located next to each lamp. To turn them off, press the
button again.
Dome Lamps
The dome lamps will come on when you open a door.
See “Dome Lamp Override” in this part for more
information.
Battery Run-Down Protection
This feature shuts off the exterior and interior lamps if
they are left on after the ignition is turned off. All exterior
lamps will shut off after ten minutes. Interior cargo
lamps will shut down after twenty minutes and all other
interior lamps after ten minutes.

Warning Lights, Gages and
Indicators
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 briey 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.

Reduced Engine Power Light
If the check engine and
reduced engine power
lights are on, the throttle
may be disabled, and
a noticeable reduction in
the vehicle’s performance
may occur.
If the reduced engine power light is on, but there is no
reduction in performance, proceed to your destination.
The performance may be reduced the next time
the vehicle is driven. The vehicle may be driven at a
reduced speed while the reduced engine power light is
on, but acceleration and speed may be reduced.
Anytime the check engine light stays on, the vehicle
should be taken to an authorized GM dealer as soon as
possible for service.
Daytime Running Lamps
Indicator Light
You have this light on the
instrument panel. It will
light whenever the DRL are
on. It is also a reminder
to turn on your headlamps
when driving at night.
Tow/Haul Mode Light
This message is displayed
when the tow/haul mode
has been activated.
For more information, see “Tow/Haul Mode” inTowing a
Trailer on page 4-37.
3-40

If the brake-traction control system activates constantly
or if the brakes have heated up due to high speed
braking, the brake-traction control will be automatically
disabled. The system will come back on after the
brakes have cooled. This can take up to two minutes or
longer depending on brake usage.
Notice:If you allow the wheel(s) of one axle to spin
excessively while the traction off, ABS, STABILITRAK
NOT READY and brake warning lights are displayed,
you could damage the transfer case. The repairs
would not be covered by your warranty. Reduce
engine power and do not spin the wheel(s)
excessively while these lights are displayed.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens you may
notice a reduction in acceleration, or may hear a noise
or vibration. This is normal.
If your vehicle is in cruise control when the system
activates, a Stabilitrak
®indicator light will appear on the
instrument panel and the cruise control will automatically
disengage. When road conditions allow you to use
cruise again, you may re-engage the cruise control. See
“Cruise Control” underTurn Signal/Multifunction Lever
on page 3-8.Stabilitrak
®may also turn off automatically if it
determines that a problem exists with the system. If the
problem does not clear itself after restarting the
vehicle, you should see your dealer for service.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
4-11

Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
Since you can not see as well, you may need to
slow down and keep more space between you
and other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime. But
as we get older these differences increase. A
50-year-old driver may require at least twice as much
light to see the same thing at night as a 20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your
eyes will have less trouble adjusting to night. But if you
are driving, do not wear sunglasses at night. They
may cut down on glare from headlamps, but they also
make a lot of things invisible.You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to re-adjust to the dark. When
you are faced with severe glare (as from a driver
who does not lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid
staring directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a lm caused by dust. Dirty glass makes
lights dazzle and ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep
your eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from
night blindness — the inability to see in dim light — and
are not even aware of it.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission uid to use. SeeRecommended
Fluids and Lubricants on page 6-12.
Using a funnel, add uid down the transmission dipstick
tube only after checking the transmission uid while it
is hot. (A cold check is used only as a reference.) If the
uid level is low, add only enough of the proper uid
to bring the level up to the HOT area for a hot check. It
doesn’t take much uid, generally less than one pint
(0.5 L).Don’t overll.
Notice:We recommend you use only uid labeled
DEXRON
®-III, because uid with that label is
made especially for your automatic transmission.
Damage caused by uid other than DEXRON
®-III is
not covered by your new vehicle warranty.
After adding uid, recheck the uid level as
described under “How to Check.”
When the correct uid level is obtained, push the
dipstick back in all the way; then ip the handle
down to lock the dipstick in place.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs rst, if you add
only DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-25.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
