Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on the vehicle. The pictures help
to 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 the 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 the vehicle’s functions. As
the details show on the next few pages, some
warning lights come on briey when the engine is
started just to indicate they are 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 the vehicle’s functions. Often
gages and warning lights work together to
indicate when there is a problem with the vehicle.
When one of the warning lights comes on and
stays on while the vehicle is being driven, or when
one of the gages shows there may be a problem,
check the section that tells you what to do
about it. Follow this manual’s advice. Waiting to
do repairs can be costly – and even dangerous.
So please get to know the vehicle’s warning lights
and gages. They can be a big help.
The vehicle also has a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information
Center (DIC) on page 186for more information.

The vehicle is equipped with this cluster or one
very similar to it. It has indicator warning lights that
are explained on the following pages. Be sure to
read about them.
Speedometer and Odometer
The speedometer shows the vehicle’s speed in
both miles per hour (mph) and kilometers per
hour (km/h). The odometer, located on the Driver
Information Center (DIC) display, shows how
far the vehicle has been driven, in either miles or
kilometers. SeeDIC Controls and Displays
(Base Level DIC) on page 186orDIC Controls
and Displays (Uplevel DIC with Trip Computer) on
page 190for more information.
If the vehicle has the Head-Up Display (HUD) the
speed will also be displayed on the HUD screen.If a vehicle has to have a new odometer installed,
a new one can be set to the mileage total of
the old odometer, if that can be done. If it cannot,
than 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, located in the Driver Information
Center (DIC), tells how far the vehicle has
driven since it was last reset. The miles
(kilometers) for two different trips can be viewed.
SeeDIC Controls and Displays (Base Level
DIC) on page 186orDIC Controls and Displays
(Uplevel DIC with Trip Computer) on page 190for
more information on setting the trip odometer.

Tachometer
The tachometer displays
the engine speed in
revolutions per
minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty. Do not
operate the engine with the tachometer in
the shaded warning area.
Safety Belt Reminder Light
When the key is turned to RUN or START, a
chime will sound for several seconds to remind
you and your passengers to buckle your
safety belts. The driver safety belt light will also
come on and stay on for several seconds, then it
will ash for several more. You should buckle
your seat belt.
If the driver’s belt is
buckled, neither the
chime nor the light will
come on.
171

Brake System Warning Light
The vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop the vehicle. For
good braking, though, both parts should be
working well.
This light should come on briey when the ignition
key is turned to RUN. If it does not come on
then, have it xed so it will be ready to warn you if
there is a problem.When the ignition is on, the brake system warning
light will also come on when the parking brake
is set. The light will stay on if the parking
brake does not release fully. If it stays on after the
parking brake is fully released, it means the
vehicle has a brake problem.
The PARKING BRAKE ON message will also
appear in the Driver Information Center (DIC)
when the parking brake is set and the vehicle is
going faster than 5 mph. SeeDIC Warnings
and Messages on page 200for more information.
The brake warning light may also come on
when the brake uid is low. If this occurs, the
LOW BRAKE FLUID message will also appear in
the Driver Information Center (DIC). SeeDIC
Warnings and Messages on page 200for more
information.
If the brake warning light comes on while the
vehicle is being driven, pull off the road and stop
carefully. The brake pedal may be harder to
push, or it may go closer to the oor. It may also
take the vehicle longer to stop. If the light is
still on, have the vehicle towed for service. See
Towing Your Vehicle on page 322.

{CAUTION:
Your brake 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 have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System
Warning Light
If the vehicle has the
Anti-lock Brake System
(ABS), this light will
come on when the
engine is started and
may stay on for several
seconds. That is normal.If the ABS warning light comes on and stays on,
there may be a problem with the anti-lock
portion of the brake system. If the brake system
warning light is not on, the vehicle still has brakes,
but it does not have anti-lock brakes. SeeBrake
System Warning Light on page 176.
If the light stays on, the vehicle needs service.
If the light comes on while the vehicle is being
driven, stop as soon as possible and turn the
ignition off. Then start the vehicle again to reset the
system. If the light still stays on, or comes on again
while driving, the vehicle needs service. If the
regular brake system warning light is not on, the
vehicle still has brakes, but it does not have
anti-lock brakes. If the brake system warning light is
also on, the vehicle does not have anti-lock brakes
and there is a problem with the regular brakes. See
Brake System Warning Light on page 176. If both
the brake system warning light and the anti-lock
brake system light is on, pull off the road and have
the vehicle towed for service.
The anti-lock brake system warning light will come
on briey when the ignition key is turned to
RUN. This is normal. If the light does not come on
then, have it xed so it will be ready to warn
you if there is a problem.

When the indicator nears empty, there is still a
little fuel left, but you should get more soon.
Here are four things owners usually ask about the
fuel gage. All these situations are normal and
do not indicate a problem with the fuel gage:
At the gas station the pump shuts off before
the gage reads full.
It takes more or less fuel to ll up than the
gage indicates. For example, the gage
reads half full, but it took more or less than
half the tank’s capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate full when the
ignition is turned off.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives
important safety and maintenance facts. When the
vehicle’s ignition is turned on, all of the DIC
lights illuminate for a few seconds and an
introductory message will appear. After this, the
DIC will begin working.
DIC Controls and Displays
