Fuel Gage (V6 Engine)
When the ignition is on, your fuel gage tells you about
how much fuel you have in your tank.
When the gage reads in the colored band, a warning
chime will sound and the CHECK GAGES warning light
will come on. You still have a little fuel left, but you
need to get more fuel right away.On vehicles with a DIC, the CHECK GAGES LOW
FUEL message will be displayed when the fuel gage
reads in the yellow band. SeeDIC Warnings and
Messages on page 3-62for more information.
Here are some things that owners ask about. None of
these show a problem with your fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more, or less, fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more, or less, than half the tank’s capacity
to ll the tank.

Messages followed by a double asterisk (**) only
apply to vehicles with the 4.6L V8 engine.SERVICE STABILITY SYSTEM – 54:If you ever see
the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system: stop, turn off the engine, then start the
engine again. If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your GM dealer for service. Reduce
your speed and drive accordingly.
STABILITY SYSTEM ACTIVE – 55:You may see the
STABILITY SYSTEM ACTIVE message on the Driver
Information Center. It means that an advanced,
computer-controlled system has come on to help your
vehicle continue to go in the direction in which you
are steering. This stability enhancement system
activates when the computer senses that your vehicle is
just starting to spin, as it might if you hit a patch of
ice or other slippery spot on the road. When the system
is on, you may hear a noise or feel a vibration in the
brake pedal. This is normal.
When the STABILITY SYSTEM ACTIVE message is on,
you should continue to steer in the direction you want
to go. The system is designed to help you in bad
weather or other difficult driving situations by making the
most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on, you
will know that something has caused your vehicle to
start to spin, so you should consider slowing down.

The rear defog system can affect accuracy, and the
compass corrects for the rear defog. However, if the rear
defog is turned on while making sharp turns, the
accuracy may be off. When you turn the rear defog off
again, the accuracy returns to normal.
Be aware that metal objects are sometimes buried in
the ground. They can affect accuracy and you may not
know they are there. As an example, many concrete
roads have metal reinforcements inside.
Also, if you drive with the trunk open, this could affect
accuracy and could decalibrate the compass.
Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added
sound equipment may interfere with the operation
of your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment
that has been added improperly.Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-24for more
information.
Setting the Time
Press and hold HR or MIN for two seconds. Then press
and hold HR until the correct hour appears on the
display. AM will appear for morning hours. Press and
hold MIN until the correct minute appears on the display.
The time can be set with the ignition on or off.
To synchronize the time with an FM station broadcasting
Radio Data System (RDS) information, press and
hold HR and MIN at the same time until UPDATED and
the clock symbol appear on the display. If the time is
not available from the station, NO UPDATE will appear
on the display.
RDS time is broadcast once a minute. After tuning to an
RDS broadcast station, it may take a few minutes for
the time to update.

Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that
your brake pedal moves or pulses a little. This is normal.
If there is a problem with the anti-lock brake system,
this warning light will stay on. SeeAnti-Lock Brake
System Warning Light on page 3-42. United States
Canada
4-6

Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System (TCS)
Your vehicle may have a traction control system that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the front wheels are spinning or
beginning to lose traction. When this happens,
the system works the front brakes and reduces engine
power to limit wheel spin.
You may feel or hear the system working, but this is
normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. SeeCruise Control
on page 3-11.
