Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel
(see ªFuelº in the Index). Poor fuel quality will cause
your engine not to run as efficiently as designed. You
may notice this as stalling after start
-up, stalling when
you put the vehicle into gear, misfiring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or may
begin programs to inspect the emission control equipment
on your vehicle. Failure to pass this inspection could
prevent you from getting a vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.

2-75 Oil Pressure Light
If your vehicle has the
standard instrument panel
cluster, this light will come
on if there is a problem with
your engine oil pressure.
If your vehicle has the optional gage cluster, you can
read your oil pressure directly from the Driver
Information Center (DIC). See ªDIC Displays and
Controlsº in the Index.
The oil light will come on briefly when you turn your
key to RUN. That's just a check to be sure the light
works. If it doesn't, be sure to have it fixed so it will be
there to warn you if something goes wrong.
But, when this light comes on and stays on, and a chime
sounds, it means oil isn't going through your engine
properly. You could be low on oil, or you might have
some other oil problem. See your dealer for service.CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

2-76 Service Vehicle Soon Light
This light will come on and
stay on if you have certain
non
-emission related
vehicle problems.
These problems may not be obvious and may affect vehicle
performance or durability. Consult a qualified dealership for
necessary repairs to maintain top vehicle performance.
This light will also come on briefly when your ignition
is turned on to show that the system is working properly.
Cruise Light
The cruise light comes on
whenever you set your
cruise control. See ªCruise
Controlº in the Index.
Fuel Gage
Standard Cluster Gage Cluster
Your fuel gage shows about how much fuel is in your
tank. It works only when the engine is on. When the
indicator nears the edge of the low fuel warning band,
the low fuel light will turn on and a chime will sound.
You still have a little fuel left, however you need to
refuel right away.

If the ignition is on and you can't see the HUD image,
check to see if:

Something is covering the HUD unit.

The HUD dimmer control is adjusted properly.

The HUD image is adjusted to the proper height.

A fuse is blown. See ªFuses and Circuit Breakersº
in the Index.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred or out of focus.
Driver Information Center (DIC)
(If Equipped)
Your vehicle may be equipped with a Driver Information
Center (DIC). The DIC will display information about
how your vehicle is functioning, as well as warning
messages if a system problem is detected. This feature also
allows two different drivers to store and recall their own
personal choice settings. See ªDIC Personal Choice
Programmingº later in this section.
DIC Displays and Controls
There are two lines in the DIC display. The DIC displays
the driver number identified when entering the vehicle.
You can have your dealer program your name to appear on
this display line. See your dealer for more information.
When you turn the ignition on, the DIC will display your
DRIVER NUMBER. The system will then perform a status
check and display any messages if a problem is detected.
If there are no problems detected, the display will return
to the mode selected by that driver the last time the
ignition was turned off.
If a problem is detected, a diagnostic message will
appear in the display. The following pages will show the
messages you may see on the DIC display.
The message center is continuously updated with the
vehicle's performance status.

SERVICE STABILITY SYSTEM - 54: If you ever
see the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system (stop; turn off the engine; then start the
engine again). If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem. You
should see your dealer for service. Reduce your speed
and drive accordingly.
STABILITY SYSTEM ACTIVE
- 55: You may see
the STABILITY SYSTEM ACTIVE message on the
Driver Information Center. It means that an advanced,
computer
-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system activates when
the computer senses that your vehicle is just starting to
spin, as it might if you hit a patch of ice or other slippery
spot on the road. When the system is on, you may hear a
noise or feel a vibration in the brake pedal. This is normal.
When the STABILITY SYSTEM ACTIVE message is
on, you should continue to steer in the direction you
want to go. The system is designed to help you in bad
weather or other difficult driving situations by making
the most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on,
you'll know that something has caused your vehicle to
start to spin, so you should consider slowing down.
