There are two ways to turn off the cruise control:
Step lightly on the brake pedal,
or move the cruise switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
or shift into PARK
(P) or NEUTRAL (N), the cruise
control set speed memory is erased.
Exterior Lamps
The exterior lamp control
is located on the lower
left side of the instrument
panel, to the left of the
steering wheel. The
exterior lamp has three positions.
OFF: Turning the control to this position, turns off all
lamps, except the Daytime Running Lamps (DRL).

The HUD also shows the following lights when they are
lit on the instrument panel cluster:
Turn Signal Indicators
High-Beam Indicator Symbol
Low Fuel Symbol
The HUD will display CHECK GAGES when the
following items are lit on the instrument panel cluster:
Oil Warning Symbol
Coolant Temperature Symbol
Charging System Symbol
When the ignition key is turned to RUN, the entire HUD
image will come on. Then the Head-Up Display will
operate normally.
Notice: Although the HUD image appears to be
near the front
of the vehicle, do not use it as
a parking aid. The
HUD was not designed for that
purpose.
If you try to use it as such, you may
misjudge the distance and damage your vehicle.
When the HUD is on, the speedometer reading will be
displayed continually. The current radio station
or
CD track number will only be displayed for three
seconds after the radio or CD track status changes.
This will happen whenever one of the radio controls is
pressed, either on the radio itself or on the optional
steering wheel controls. To
adjust the HUD
so you can see it properly do the
following:
1. Adjust your seat, if necessary, to a comfortable
position.
2. Start the engine and adjust the HUD controls
located on the instrument panel, to the right
of
the steering wheel. Move the DIM thumbwheel up
or down to adjust brightness.

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 may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. See Driver Information Center (DIC)
on page 3-38.
3-23

Your vehicle is equipped with this cluster or one very
similar to it. It includes indicator warning lights and
gages that are explained on the following pages.
Be sure to read about them.
Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). The
odometer shows how far the vehicle has been driven in
either miles (used in the United States) or in kilometers
(used in Canada).
The vehicle has a tamper-resistant odometer.
If you see
silver lines between the numbers, you’ll know someone
has probably tampered with
it and the numbers may
not be correct.
You may wonder what happens
if the vehicle needs a
new odometer installed.
If the new one can be set to the
mileage total of the old odometer, then that will be
done.
If it can’t, then it will be set at zero and a label
must be put on the driver’s door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
The trip odometer tells how far you have driven since
you last reset it.
To set it to zero, press the reset button
located to the right of the instrument panel cluster.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Notice: Do not operate the engine with the
tachometer in the shaded warning area, or engine
damage may occur.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts.
If one part isn’t working, the other part can still
work and stop you. For good braking, though, you
need both parts working well.
If the light comes on while you are driving, carefully pull
off the road and stop. You may notice that the pedal
is harder to push. Or, the pedal may go closer to
the floor. It may take longer to stop.
If the light is still
on, have the vehicle towed for service. See Towing
Your
Vehicle on page 4-33.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
I 3 I I
United States
Canada
This light should come on when you turn the key to
RUN. If it doesn’t come on then, have it fixed so it will
be ready to warn you
if there’s a problem.
Your oraKe system may not be working
properly
if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you’ve pulled off the road and stopped
carefully, have the vehicle towed for service.
While the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on
if your parking brake doesn’t
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
3-28

Anti-Lock Brake System Warning Light
if your vehicle has the
optional anti-lock brake
system, this light will come
on when your engine is
started and may stay on
for several seconds.
That’s normal.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition
off. If the light comes on and stays on
while you’re driving, stop as soon as possible and turn
the ignition
off. Then start the engine again to reset
the system.
If the light still stays on, or comes on again
while you’re driving, your vehicle needs service.
If
the light is on and the regular brake system warning
light isn’t on, you still have brakes, but you don’t have
anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. This is
normal.
If the light doesn’t come on then, have it
fixed
so it will be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
TCS
OFF
If your vehicle is
equipped with the 3800
supercharged V6 engine,
the traction control
system warning light
may come on for the
following reasons:
If you turn the system off by pressing the TCS
button located on the far right side of the trip
computer, the warning light will come on and stay
on. To turn the system back on, press the button
again. The warning light should go
off. See Traction
Control System (TCS) on page
4-10 for more
information.
@ If there’s a brake system problem that is specifically
related to traction control, the traction control
system will turn
off and the warning light will come
on. If your brakes begin to overheat, the traction
control system will turn
off and the warning light will
come on until your brakes cool down.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system
is turned on, your vehicle needs service.
3-29

Enhanced Traction System Warning
Light
TRAC
OFF
If your vehicle is equipped
with a
31 00 V6 or 3800 V6
engine and the optional
ABS brake system, the
Enhanced Traction System
warning light may come on
for the following reasons:
e

If you turn the system off by pressing the TRAC
button on the far right side of the Driver Information
Center or trip computer (if equipped), the warning
light will come on and stay on. To turn the system
back on, press the button again. The warning light
should go
off. See Enhanced Traction System (ETS)
on page 4-1 1 for more information.
If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time while the system is turned on, your vehicle
needs service. Adjust your driving accordingly.
If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
Low Traction Light
LOW
TRAC
If your vehicle has the
Enhanced Traction
System or the Traction
Control System, this light
will also come on while
the system is limiting
wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist
if the
low traction light comes on,
so adjust your driving
accordingly. The light will stay on for a few seconds after
the Enhanced Traction System or the Traction Control
System stops limiting wheel spin. See Enhanced
Traction System
(ETS) on page 4-1 1 or Traction Control
System (TCS) on page
4- 10.
The low traction light also comes on briefly when you
turn the ignition key to RUN. If the light doesn’t come on
then, have it fixed so it will be there to tell you when
the Traction Control System or Enhanced Traction
System is active.

Engine Coolant Temperature
Warning Light
TEMP
This light tells goti ihai
the engine coolant has
overheated or the
radiator cooling fan is
not working.
If you have been operating the vehicle under normal
driving conditions, you should pull
of the road, stop the
vehicle and turn
off the engine as soon as possible.
See Engine Overheating on page
5-33.
Engine Coolant Temperature Gage
United States

Canada
Your vehicle has a gage that shows the engine coolant
temperature.
If the gage pointer moves into the
shaded area, the engine is too hot.
That reading means the same thing as the warning
light. It means that the engine coolant has overheated.
If you have been operating the vehicle under normal
conditions, you should pull
off the road, stop the vehicle,
and turn
off the engine as soon as possible.
See Engine Overheating
on page 5-33.
