Tachometer
The tachometer displays
the engine speed in
thousands of 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 ON, a chime will come on
for about several seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will ash for
several more.

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.

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
If your vehicle has the
traction control system,
this warning light may
come on for the following
reasons:
If you turn the system off by pressing the TRAC OFF
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.
SeeEngine Overheating on page 5-34.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (On-Board Diagnostics-
Second Generation) and is intended to assure that
emissions are at acceptable levels for the life of
the vehicle, helping to produce a cleaner environment.
The CHECK ENGINE light comes on to indicate
that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.Notice:If you keep driving your vehicle with this
light on, after a while, your emission controls may
not work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions and
may damage the emission control system on your
vehicle. Diagnosis and service may be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required. United States
