Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages on
your 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 your vehicle’s functions. As the
details show on the next few pages, some warning lights
come on briey when you start the engine just to let
you know 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 your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
as 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 vehicle’s
warning lights and gages. They can be a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with warning lights and gages.
SeeDIC Warnings and Messages on page 3-63for
more information.

Instrument Panel Cluster
Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the
vehicle is running. You will know how fast you are going, about how much fuel you have left and many other things
you will need to know to drive safely and economically. The instrument panel cluster indicator warning lights, gages
and DIC messages are explained on the following pages.
United States Base Cluster shown, Canada and Uplevel similar
3-44

If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be a
problem with the lights or the passenger sensing system.
See your dealer/retailer for service.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the airbag(s). SeeAirbag Readiness Light
on page 3-46for more on this, including
important safety information.
Charging System Light
This light will come on
briey when you turn
on the ignition, but
the engine is not running,
as a check to show
you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system. A charging system
Driver Information Center (DIC) message may also
appear. SeeDIC Warnings and Messages on page 3-63
for more information. This light could indicate that you
have problems with a generator drive belt, or another
electrical problem. Have it checked right away.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as
the radio and air conditioner.

REDUCED ENGINE POWER
This message displays when the vehicle is reducing
engine power because the transmission is being placed
in gear under conditions that may cause damage to
the vehicle’s engine, transmission, or ability to
accelerate. Reduced engine power can affect the
vehicle’s ability to accelerate. If this message is on,
but there is no reduction in performance, proceed
to your destination. The performance may be reduced
the next time the vehicle is driven. The vehicle may
be driven at a reduced speed while this message is on,
but acceleration and speed may be reduced. Anytime
this message stays on, the vehicle should be taken
to your dealer/retailer for service as soon as possible.
RIGHT DOOR AJAR
This message displays anytime the engine is running,
the transmission is not in PARK (P), and the passenger
door is open or ajar. A chime sounds if the vehicle’s
speed is greater than 3 mph (5 km/h).
SERVICE A/C
This message displays when the electronic sensors that
control the air conditioning and heating systems are
no longer working. Have the climate control system
serviced by your dealer/retailer if you notice a drop in
heating and air conditioning efficiency.
SERVICE ABS (Antilock Brake System)
If this message displays when you are driving, stop
as soon as possible and turn the ignition off. Then start
the engine again to reset the system. If the message
stays on, or comes back on again while you are driving,
your vehicle is in need of service. See your
dealer/retailer.
If the SERVICE ABS message is being displayed, the
Traction Control System (TCS) and StabiliTrak
®System
will also be disabled. The Driver Information Center
will scroll three messages: SERVICE ABS, SERVICE
TRACTION SYS, and SERVICE STABILITRAK, and the
antilock brake system and traction control warning
lights on the instrument panel cluster will be illuminated.
SeeAntilock Brake System Warning Light on page 3-51
andTraction Control System (TCS) Warning Light on
page 3-52. The driver can acknowledge these messages
by pressing the RESET button three times. When the
service message is displayed, the computer controlled
systems will not assist the driver and you should
have the system repaired by your dealer/retailer as
soon as possible. Adjust your driving accordingly.

Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission uid level.
A transmission uid leak is the only reason for uid
loss. If a leak occurs, take the vehicle to the
dealer/retailer service department and have it repaired
as soon as possible.
There is a special procedure for checking and changing
the transmission uid. Because this procedure is difficult,
you should have this done at the dealer/retailer service
department. Contact your dealer/retailer for additional
information or the procedure can be found in the service
manual. To purchase a service manual, seeService
Publications Ordering Information on page 8-16.
Notice:Use of the incorrect automatic transmission
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 7-11.
Change the uid and lter at the intervals listed in
Additional Required Services on page 7-5, and be sure
to use the uid listed inRecommended Fluids and
Lubricants on page 7-11.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, seeEngine Overheating on
page 6-27.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Giving freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
