If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady,
see ªIf the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
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.
Are you low on fuel?
As your engine starts to run out of fuel, your engine
may not run as efficiently as designed since small
amounts of air are sucked into the fuel line causing a
misfire. The system can detect this. Adding fuel should
correct this condition. Make sure to install the fuel cap
properly. See ªFilling Your Tankº in the Index.
It will take a few driving trips to turn the light off.

2-91
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 or CHECK ENGINE
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.

Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to ON. It goes
off once you start your engine. That's a check to be sure
the light works. If it doesn't come on, be sure to have
it fixed so it will be there to warn you if something
goes wrong.
When the light comes on and stays on, it means that
oil isn't flowing through your engine properly. You
could be low on oil and you might have some other
system problem.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.

BATTERY VOLTAGE LOW - 6: This message
will appear when the electrical system is charging less
than 10 volts or if the battery has been drained. If this
message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may take a
few hours to do so. Consider using an auxiliary charger
(be sure to follow the manufacturer's instructions) to
boost the battery after returning home or to a final
destination. If this message appears while driving or
after starting your vehicle and stays on, have it checked
immediately to determine the cause of this problem.
To help the generator recharge the battery quickly, you
can reduce the load on the electrical system by turning off
the accessories. You can monitor battery voltage on the
DIC by pressing the INFO button. The normal range
is 11.5 to 15.5 volts.
CHANGE ENGINE OIL

life of the engine oil has expired and it should be
changed within 200 miles. See ªEngine Oilº and
ªFilter Recommendationsº in the Maintenance Schedule
booklet. After an oil change, the Oil Life Indicator must
be reset. See ªOil Life Indicator, How to Resetº in
the Index.CHANGE TRANS FLUID

You can continue to drive your vehicle. If this message
continues to appear, have the system repaired as soon as
possible to avoid compressor damage.
ENGINE OVERHEATED, STOP ENGINE
- 42: This
message will appear when the engine has overheated.
Stop and turn the engine off immediately to avoid severe
engine damage. See ªEngine Overheatingº in the Index.
A multiple chime will also sound when this message

informs you that the vehicle is reducing engine power
because the transaxle is being placed in gear under
conditions that may cause damage to the vehicle's
engine, transaxle or ability to accelerate.FUEL LEVEL LOW

Remember that the Night Vision System can only
help you see objects that are warmer or colder than the
surroundings. It can't sense things like brake lights,
turn signals or emergency flashers, traffic lights or signs.
In dry, clear weather, the system can see pedestrians,
animals and the direction of the road ahead. In light rain,
light snow or light fog the image may not be as clear
and you may not be able to see the direction of the road
ahead. In more severe weather conditions, the image
may be unclear and not usable.
CAUTION:
Don't use the Night Vision System to replace
your normal view of the road ahead. It can't
tell you how far away things are. It senses only
warmer or colder objects, not all objects. Driving
by staring at the image might cause you not to
see important objects in the road ahead. If you
don't see something in time, you could have a
crash in which you and others could be injured.
Use the Night Vision System only as a driving aid.
It is also important to keep your windshield, the HUD
(Head
-Up Display for the night Vision System) lens and
the camera lens clean. If you do not keep everything
clean, system performance may be affected. The HUD
system is located on the driver's side of the instrument
panel, next to the windshield and the camera is located
behind the center of the front grille. Use only household
glass cleaner and a soft cloth. Wipe gently and
dry thoroughly.
NOTICE:
When cleaning, be careful not to scratch the
HUD or camera lenses. Do not spray glass
cleaner directly on the HUD lens because
the cleaner could leak inside the unit and
cause damage.
The camera must also be aligned to work correctly.
If the camera needs adjustment, see your dealer.
Do not attempt to adjust the camera yourself.
