two parts.
If one part isn’t working, the other part can

take your vehicle to the dealer at once.
To save your
battery until you get there, turn off all accessories. This light should come
on briefly when you turn
the ignition key to RUN. If

Analog Cluster
This gage shows the
engine coolant
temperature. If the gage
pointer moves into the red area, the engine is too hot.
That reading means the same thing as the warning
light
-- the engine coolant
has overheated.
In the
section “Problems on the
Road,” this manual
explains what to do. See
“Engine Overheating” in
the Index.
Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems. SERVICE
ENGINE
SOON
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The
SERVICE ENGINE SOON light
comes on and a chime will sound to indicate that there is
a problem and service is required. Malfunctions often
will be indicated by the system before
any problem is
apparent. This may prevent more serious damage
to
your vehicle. This system is also designed to assist your
service technician in correctly diagnosing
any
malfunction.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work
as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and service may be required.
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.
0 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 “If
the Light
Is On Steady’’ 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 “If the Light
Is On Steady’’ following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.

The fuel gage shows approximately how much fuel is in
the tank. It works only when the ignition is
in RUN.
On the digital cluster, if the fuel level is within
approximately 2 gallons (7.6 L) of being full, the letter F is
shown. If the fuel level is less than approximately
3 gallons (1 1.4 L) from being empty, the letter E is shown.
If the fuel supply gets down to approximately 3 gallons
(11.4 L), the number “3” will be displayed on the fuel
gage, and the
FUEL LEVEL LOW message will appear
on the Driver Information Center
@IC). (On the analog
fuel gage, the
FUEL LEVEL LOW message will
also appear.)
Here are a few concerns some owners have had about
the fuel gage. All
of these situations are normal and do
not indicate that anything is wrong with the fuel gage:
At the gas station the gas pump shuts off before the
gage reads
E
It takes more (or less) gas to fill the tank than the
gage said. For example, the gage read
8 GALLONS
(30 L), but it took more (or less) than the tank’s
remaining capacity to fill it.
