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.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 3-52.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, seeAir Bag Systems on page 1-48.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should
go out. This means the
system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they

Voltmeter Gage
If your vehicle is equipped
with the 3800 V6 engine it
has a voltmeter gage
that indicates battery
voltage.
If the gage reads less than 12 volts or more than
16 volts while the engine is running, and it stays there,
you may have a problem with the electrical charging
system.
Also, when your gage reads less than 11 volts or more
than 16 volts, your battery life indicator will be
illuminated in the message center. For more information
seeBattery Warning Message on page 3-45.
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 warning light comes on, there is a brake problem.
The LOW BRAKE FLUID message in the message
center will also appear when there is a brake problem.
SeeLow Brake Fluid Warning Message on page 3-50.
Have your brake system inspected right away.

This light should come on briey when you turn the
ignition key to ON. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a problem.
When 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.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeBrake System
Warning Light on page 3-35andTowing Your Vehicle on
page 4-31.
{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 your vehicle has ABS,
the anti-lock brake system
warning light will come
on for a few seconds when
you turn the ignition key
to ON.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine,
turn the ignition off. Or, if the light comes on and stays
on when 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, the anti-lock brake system
needs service and you don’t have anti-lock brakes.
The anti-lock brake system warning light will come on
briey when you turn the ignition key to ON. This is
normal. If the light doesn’t come on then, have it xed
so it will be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light

button located on the center console, a chime will
sound and 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. SeeTraction
Control System (TCS) on page 4-10for more
information.
If there’s a brake system problem that is specically
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.

Engine Coolant Temperature GageThis gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle
is working. During the majority of the operation,
the gage will read 210°F (100°C) or less.
If you are pulling a load or going up hills, it is normal
for the temperature to uctuate and approach the
250°F (122°C) mark. When the gage reads greater than
250°F (122°C), the HOT COOLANT TEMP light will
be illuminated in the message center and a chime
will sound continuously. If the gage reaches the
260°F (125°C) mark, it indicates that the cooling system
is working beyond its capacity.
