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 may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 3-55for more information.

Instrument Panel Cluster
The instrument panel cluster is designed to show at a glance how the vehicle is running. It will show how fast the
vehicle is going, about how much fuel is in the fuel tank, and many other things needed to drive the vehicle safely
and economically.
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.United States version shown, Canada similar

{CAUTION:
Even though the passenger sensing system is
designed to turn off the right front passenger’s
frontal airbag if the system detects a rear-facing
child restraint, no system is fail-safe, and no
one can guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be secured in the
rear seat, even if the airbag is off.
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger’s frontal
airbag. SeePassenger Sensing System on page 1-60
for more on this, including important safety information.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 3-42for more on this, including
important safety information.

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 Operation and Displays
(Uplevel DIC with Trip Computer)
The Driver Information Center (DIC) control buttons and
the message display screen are located above the
radio. The DIC gives important safety and maintenance
facts concerning the vehicle. The status of many of
the vehicle’s systems along with driver personalization
menus and warning messages about the vehicle’s
systems may display on the DIC screen.
The outside temperature automatically appears on
the bottom right corner of the DIC display screen.
If the outside temperature is below 38°F (3°C), the
temperature reading will toggle between displaying the
outside temperature and the word ICE for two minutes.
If there is a problem with the system that controls
the temperature display, the letters OC (Open Circuit)
or SC (Short Circuit) will appear on the display.
If this occurs, have the vehicle serviced by your
dealer/retailer.The vehicle’s shift lever position and the direction the
vehicle is traveling will also appear on the DIC screen.
The compass is self-calibrating, which eliminates
the need to manually set the compass. However, under
certain circumstances, such as during a long distance
cross-country trip, it will be necessary to compensate
for compass variance and reset the zone through
the DIC. SeeDIC Compass (Uplevel DIC) on page 3-65
for more information.
The buttons on the DIC trip computer are gages,
trip odometer, set/reset, options, and fuel.

This message displays when a door or the trunk is not
closed properly. If your vehicle has the remote start
feature, this message also displays when the hood is not
closed properly. The graphic highlights the area that

message has been acknowledged, but the condition still
exists when the engine is turned off.
If the condition still exists, the message re-appears
when the engine is turned on.
BATTERY SAVER ACTIVE
This message displays when the system detects that the
battery voltage is dropping beyond a reasonable level.
The battery saver system starts reducing certain features
of the vehicle which you may be able to notice. At the point
that the features are disabled, this message is displayed.
It means that the vehicle is trying to save the charge in
the battery. Turn off all unnecessary accessories to allow
the battery to recharge. The normal battery voltage range
is 11.5 to 15.5 volts. If your vehicle has the uplevel DIC,
you can monitor battery voltage on the DIC by pressing
the gages button until BATTERY appears.
CHANGE OIL SOON
This symbol comes on
with this message.
This message displays when service is required for the
