[IS05550(ALL)03/96]
The Electronic 4-Wheel Drive Warning Light
illuminates when the Electronic 4-Wheel Drive
system is not working properly. This light
illuminates briefly when you turn the ignition
key to the ON position, but should turn off
when the engine starts. If the light does not
illuminate when you turn the ignition to the ON
position, or if it illuminates and stays on when
you are driving, have your vehicle serviced as
soon as possible.
[IS05560(ALL)03/96]
The 4WD light will go off after a few seconds
and stay off if all systems are operating
correctly. If a problem is detected, the 4WD
warning light will flash a certain number of
times indicating the location of the problem. The
flashing will continue until the problem is
corrected. Each time the ignition key is turned
on, the controller will detect the problem and
flash the signal. The 4WD system remains safe to
operate and the vehicle should be returned for
service.

This gauge shows you the battery voltage when
the ignition key is in the ON position.

[IS06700(ALL)01/96]
If you are running electrical accessories (when
the engine is off, or idling at a low speed), the
pointer may move toward the lower end of the
normal band. If it stays outside the normal band
area, have your vehicle's electrical system
checked as soon as it is safely possible.

Engine Oil Pressure Gauge
*
[IS07601(ALL)01/96]
This gauge indicates the engine's oil pressure,
not the oil level. However, if your engine's oil
level is low, it could affect the oil pressure. With
the engine running, the pointer should move
into the NORMAL band. If the pointer drops
below the NORMAL band while the engine is
running, you have lost oil pressure and
continued operation will cause severe engine
damage.

If you lose engine oil pressure:

[IS08001(ALL)01/96]
3. Check the engine's oil level, following the
instructions on checking and adding engine
oil. Refer toEngine oilin the Index. If you
do not follow these instructions, you or
others could be injured. To assure an
accurate reading, your vehicle should be on
level ground.
*
[IS08051(ALL)01/96]
4. If the level is low, add only as much oil as
necessary before you start the engine again.
Do not overfill. Do not operate the engine if
the pointer is below the NORMAL band,
regardless of the oil level. Contact your
nearest dealer for further service actions.

Speedometer

[IS12700(ALL)03/96]
The speedometer tells you how many miles
(kilometers) per hour your vehicle is moving.
*
[IS12750(ALL)03/96]
Your vehicle contains a speedometer which
receives its input from the Anti-Lock brake
sensor. The speedometer is also used to provide
a speed signal for correct operation of the
vehicle's Powertrain Control Module (PCM),
electronic transmission, and speed control (if so
equipped). Because of this, it is very
IMPORTANT to change the speedometer's
internal conversion constant if the size of the
tires on the vehicle is changed. Changing the
conversion constant to the proper value when

A computer system controls the engine's idle
speed. When you start your vehicle, the engine's
idle speed normally runs high. These faster
engine speeds will make your vehicle coast
slightly faster than its normal idle speed. It
should, however, slow down after a short time.
If it does not, have the idle speed checked.
*
[TO07390(ALL)01/96]
If the engine idle speed does not slow down
automatically, do not allow your vehicle to idle
for more than 10 minutes. Have the vehicle
checked.

[TO07400(ALL)01/96]
RWARNING
Extended idling at high engine speeds can
produce very high temperatures in the
engine and exhaust system, creating the
risk of fire or other damage.

Guarding Against Exhaust Fumes
*
[TO09400(ALL)01/96]
Carbon monoxide, although colorless and
odorless, is present in exhaust fumes. Take
precautions to avoid its dangerous effects.

RWARNING
If you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes.
[TO09700(ALL)04/96]
If your vehicle has rear windows and doors that
were installed as part of a van conversion, close
them while it is running. This prevents exhaust
fumes from being drawn into the passenger
compartment.
