Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
ANTI -
LOCK
on when you start your
engine and may stay on for
several seconds.
That’s normal.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system
warning light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there is a problem.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read
2 10 OF ( 100 ” C) or less. If you are pulling a
load or going up hills, it is normal for the temperature
to
fluctuate and approach the 260 OF( 160” C) mark. If the
gage reaches the
260”F( 160°C) mark, it indicates that
the cooling system
is working beyond its capacity.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Malfunction Indicator Lamp (Service
Engine Soon Light) (Gasoline Engine)
SERVICE
ENGINE
SOON
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (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. (In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE SOON
light comes on 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.
I 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
is required.
0 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.

Fuel Gage
When the ignition is on, the
fuel gage tells you about
how much fuel you have
left in your tank.
The gage will first indicate
EMPTY (E) before you are
out
of fuel, and you should get more fuel as soon
as possible.
Listed
are four situations you may experience with your
fuel gage:
At the gas station, the fuel pump shuts off before the
gage reads FULL (F).
It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may have
indicated the tank was half full, but
it actually took a
little more or less than half the tank’s capacity to fill
the tank.
The gage moves a little when you turn a corner or
speed up.
The gage doesn’t go back to EMPTY (E) when you
turn off the ignition.
None
of these indicate a problem with the fuel gage.
For information on how to fill your fuel tank,
see “Fuel
-- Filling Your Tank” in the Index.
For your fuel tank capacity, see “Fuel
-- Tank Capacity”
in the Index.
For the diesel engine fuel gage, see your Diesel
Engine Supplement.

Defogging and Defrosting
On cool, humid days, use DEFOG to keep the
windshield and side windows clear. Use DEFROST to
remove fog or ice from the windshield in extremely
humid or cold conditions. Use DEFROST with the
temperature knob toward the red area and the fan control
toward HI.
Rear Window Defogger (If Equipped)
If you see lines running across the rear window, you
have a rear window defogger. The lines warm the glass.
To
turn on the rear window
defogger, press this button
next to the fan control
knob.
The rear window defogger
will only work if the ignition
switch is turned to RUN. For
best results, first clear the
window of as much snow
or ice as possible. The
defogger will shut itself off after several minutes. If
you need additional warming time, press the button
again.
You can turn the defogger off at any time by
pressing the button.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Don’t use a razor blade or something else sharp
on the inside
of the rear window. If you do, you
could cut or damage the warming grid, and the repairs wouldn’t be covered by your warranty.

audio system adjusts automatically to make up
for road and wind noise
as
you drive. Set the volume at the
desired level. Move the control ring behind the upper
knob clockwise to adjust the SCV. Then, as you drive,
SCV automatically increases the volume, as necessary,
to overcome noise at any particular speed. The volume
level should always sound the same to
