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 brie y 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 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 are a
big help.
Your vehicle has a DIC that works along with the
warning lights and gages. SeeDriver Information
Center (DIC) on page 212.
Instrument Panel Cluster
Your instrument panel cluster is designed to let
you know at a glance how your vehicle is running.
You will know how fast you are going, how
much fuel you have, and many other things you
will need to drive safely and economically.

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety
belt. This would only occur if the passenger airbag
is enabled. SeePassenger Sensing System on
page 81for more information. The passenger
safety belt light will also come on and stay on for
several seconds, then it will ash for several more.
This chime and light
will be repeated if the
passenger remains
unbuckled and the
vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for
malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensors, the airbag modules, the wiring and
the diagnostic module. For more information on the
airbag system, seeAirbag System on page 70.
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.

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display
located below the speedometer in the instrument
panel cluster. The DIC buttons are located on
the instrument panel, to the left of the instrument
panel cluster.
The DIC comes on when the ignition is on. After a
short delay, the DIC will display the information
that was last displayed before the engine was
turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system
problem is detected. The bottom line of the
DIC shows the shift lever position indicator.
SeeAutomatic Transaxle Operation on page 119
for more information.If your vehicle’s DIC has these features, the
compass direction and the outside air temperature
may also display on the DIC when viewing the
trip and fuel information. The compass direction
appears on the top right corner of the DIC display.
The outside air temperature automatically
appears in the bottom right corner of the DIC
display. If there is a problem with the system that
controls the temperature display, the numbers
will be replaced with dashes. If this occurs, have
the vehicle serviced by your dealer.
The DIC also allows some features to be
customized. SeeDIC Vehicle Customization on
page 231for more information.
DIC Controls and Displays
The DIC has different displays which can be
accessed by pressing the DIC buttons located on
the instrument panel, to the left of the instrument
