Modification or additions to the vehicle may
cause incorrect operation of the OBD II system.
Additions such as burglar alarms, cellular
phones, and CB radios must be carefully
installed. Do not install these devices by tapping
into or running wires close to powertrain control
system wires or components.

[IS05100( ALL)01/96]
The light comes on briefly when you turn the
ignition key toON, but it should turn off when
the engine starts. If the light does not come on
when you turn the ignition toONor if it comes
on and stays on when you are driving, have
your vehicle serviced as soon as possible. This
indicates a possible problem with one of the
vehicle's emission control systems. You do not
need to have your vehicle towed in.
*
[IS05200( ALL)01/96]
If the light turns on and off at one (1) second
intervals while you are driving the vehicle, it
means that the engine is misfiring. If this
condition persists, damage could occur to the
engine or catalytic convertor. Have your vehicle
serviced at the first opportunity. You do not
need to have your vehicle towed in.
*
[IS05300( ALL)01/96]
If the light turns on and off on rare occasions
while you are driving, it means that a
malfunction occurred and the condition corrected
itself.
*
[IS05500( ALL)01/96]
An example of a condition which corrects itself
occurs when an engine running out of fuel
begins to misfire. In this case, the Check Engine
Warning Light may turn on and will then set a
Diagnostic Trouble Code indicating that the
engine was misfiring while the last of the fuel
was being consumed. After refueling, the Check
Engine Warning Light will turn off after the
vehicle has completed three consecutive warm

14up cycles without a misfire condition occurring.
A warm up cycle consists of engine start from a
cold condition (engine at ambient temperature)
and running until the engine reaches normal
operating temperature.
*
[IS05600( ALL)01/96]
On the fourth engine start up, the Check Engine
Warning Light will turn off as soon as the
engine begins to crank. It is not necessary to
have the engine serviced.
*
[IS05700( ALL)01/96]
Under certain conditions, the Check Engine
Warning Light may come on if the fuel cap is
not properly installed. If the Check Engine
Warning Light comes on and you suspect that
the fuel cap is not properly installed, pull off the
road as soon as it is safely possible and turn off
the engine. Remove and replace the fuel cap,
making sure it is properly seated.
*
[IS05800( ALL)01/96]
After completing the three consecutive warm up
cycles and on the fourth engine start up, the
Check Engine Warning Light should turn off. If
the light does not go off after the fourth engine
restart, have your vehicle serviced by your
dealer or a qualified technician.

This light comes on every time you turn the
ignition to the ON or START position (engine
off). The light should go off when the engine
starts and the alternator begins to charge.

Battery Voltage Gauge (Voltmeter)
*
[IS07200( ALL)01/96]
This gauge shows you the battery voltage when
the ignition key is in the ON position.
*
[IS07300( 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.
*
[IS07400( ALL)01/96]
If the battery is operating under cold weather
conditions, the pointer may indicate in the upper
range of the NORMAL band while the battery is
charging. If you are running electrical accessories
with the engine off or idling at a low speed, or
the battery is not fully charged, the pointer may
move toward the lower end of the NORMAL
band.
*
[IS07500( ALL)01/96]
If it stays outside the NORMAL band, have your
vehicle's electrical system checked as soon as it
is safely possible.

Engine Oil Pressure Gauge
*
[IS07900( 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.
*
[IS08000( ALL)01/96]
If you lose engine oil pressure:
*
[IS08100( ALL)01/96]
1. Pull off the road as soon as safely possible.
*
[IS08200( ALL)01/96]
2. Shut off the engine immediately or severe
engine damage could result.
*
[IS08300( 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.
*
[IS08400( 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.

Fuel Gauge

[IS09300( ALL)01/96]
The fuel gauge displays approximately how
much fuel is in the fuel tank only when the
ignition switch is ON.
*
[IS09400( M)01/96]
For a proper fuel gauge indication after adding
fuel, the ignition switch should be in the OFF
position while the vehicle is being refueled.
*
[IS09500( ALL)01/96]
The fuel gauge indicator may vary slightly when
the vehicle is in motion.
*
[IS09600( ALL)01/96]
With ignition switch OFF, the fuel gauge
indicator may drift from the ignition switch ON
position.

Engine Coolant Temperature Gauge
*
[IS10000( ALL)01/96]
This gauge tells you the temperature of the
engine coolant, not the coolant level. If the
coolant is not at its proper level or mixture, the
gauge indicator will not be accurate.
*
[IS10100( ALL)01/96]
The pointer moves from the C (cold) mark into
the Normal band as the engine coolant warms
up. It is acceptable for the pointer to fluctuate
within the Normal band under normal driving
conditions. Under certain driving conditions,
such as heavy stop and go traffic or driving up
hills in hot weather, the pointer may move to
the top of the Normal band.
*
[IS10200( ALL)01/96]
If, under any circumstances, the pointer moves
above the NORMAL band, the engine coolant is
overheating and continued operation may cause
engine damage.
*
[IS10300( ALL)01/96]
If your engine coolant overheats:
*
[IS10400( ALL)01/96]
1. Pull off the road as soon as it is safely
possible.
*
[IS10500( ALL)01/96]
2. Turn off the engine. If you do not stop the
engine as soon as safely possible, severe
engine damage could result.

instructions on checking and adding coolant
to your engine, seeEngine Coolantin the
Index. If you do not follow these
instructions, you or others could be injured.

Speedometer
*
[IS11200( ALL)01/96]
The speedometer tells you how many miles
(kilometers) per hour your vehicle is moving.
[IS11400( M)01/96]
Your vehicle contains a speedometer which
receives its input from a speed sensor. The
speedometer is also used to provide a speed
signal for correct operation of the vehicle's
Electronic Engine Control (EEC) module,
electronic transmission, and speed control (if so
equipped).
