INSTRUMENT CLUSTER DESCRIPTION
Your vehicle is equipped with the instrument cluster
described on the following pages.
1. Voltmeter
Indicates available battery voltage and charging
system operation. The lower red zone indicates
that battery charge may be too low to start the engine.
With the engine running, the normal operating range
is between 11 and 15 volts. Prolonged gauge readings
between 8-11 (undercharge) or above 15 (overcharge)
indicate possible malfunction of generator, voltage
regulator or battery. See your dealer if such indications
occur.

Radio Security Code
This radio is equipped with an anti-theft feature which
requires that a four digit code number be entered when-
ever the power supply is interrupted (such as a discon-
nected battery). The four digit code can be found on the
last page of this manual. Please remove this page from
the manual and store it in a safe place outside of the
vehicle.To enter the code, turn the key to the ON or ACC position
and press the ON/VOL control. The word CODE will
appear on the display. Enter your four digit code by
pressing the appropriate preset buttons in sequence. Your
radio is now ready for basic operation.
If an invalid code is entered into the radio, the radio will
allow two more attempts. After a third attempt of enter-
ing an invalid code, the radio will go into a lockup mode.
This is to prevent continuous attempts at entering the
wrong code until the right code is found.
Once a radio is in this lockup mode, it must be in a state
where battery is applied for approximately 30 minutes.
During this time, if the radio is on, the display will show
ªWAITº. After approximately 30 minutes, (radio on)
radio will display ªCODEº thereby again querying the
operator for the 4 digit anti-theft code.
Operating Instructions - Radio Mode
NOTE:
Power to operate the radio is supplied through

HAZARD WARNING FLASHER
The flasher switch is on top of the steering column, just
behind the steering wheel. Depress the switch and both
cluster indicators and all front and rear directional sig-
nals will flash. Depress the switch again to turn Hazard
Warning Flashers off.Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE:With extended use, the flasher may wear down
your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
²On the highways Ð Slow down.
²In city traffic Ð While stopped, put transmission in N
(Neutral), but do not increase engine idle speed.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
210 WHAT TO DO IN EMERGENCIES

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle's OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off
the ignition key or start the engine. This means that
your vehicle's OBD system isnot readyand you
shouldnotproceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or
start the engine. This means that your vehicle's OBD
system isreadyand you can proceed to the I/M
station.
