between 20 and 80 psi (pounds per square inch). If the
pointer remains in the red range, safely bring the vehicle
to a complete stop and turn off the engine. DO NOT
operate the vehicle until the cause is corrected.
This gauge does not indicate the amount of oil in the
engine. The engine oil level must be checked under the
hood. Check the level often during severe usage.
Oil Pressure Warning Light
The red Oil Pressure Warning Light is located in
the Oil Pressure Gauge. It will turn on to indicate
low engine oil pressure. The light should turn on briefly
as a bulb check when the engine is first started. If the
light remains on or turns on while driving, safely bring
the vehicle to a complete stop and turn off the engine. DO
NOT operate the vehicle until the cause is corrected.NOTE:This light does not indicate how much oil is in
the engine. The engine oil level must be checked using
the procedure shown in section 7. (See page 198 for more
information.)
Fuel Gauge
This gauge shows the amount of fuel in the gas
tank. The reaction time of the gauge has been
slowed to avoid needle fluctuation during pe-
riods of high G force cornering.
Voltage Gauge
This gauge shows the electrical system voltage.
The normal operating voltage is from 12 to 14
volts with the engine running. If the pointer
remains at either the high or low ends of the
scale, the electrical system should be serviced.

Charge System Light
The red Charge System Light is located in the
Voltage Gauge. It will turn on when there is a
charging system malfunction or a possible accessory
drive belt failure.
CAUTION!
The accessory belt also drives the water pump. Op-
erating the vehicle with a failed belt can cause engine
overheating and possible severe engine damage.
SETTING THE DIGITAL CLOCK
The digital display panel on the radio displays the time in
hours and minutes. The display panel is operative when
the ignition switch is in the ON/RUN or ACC position.
Press and release the Time button on the radio to display
the time. Press and release the button a second time to
turn off the time display.
Clock Setting Procedure
1. Turn the ignition switch to the ªON/RUNº or ªACCº
position.
2. Using the point of a ballpoint pen or similar object,
press either the ªHº (Hour) or ªMº (Minute) button on
the radio. The display will show the time.
3. Press the ªHº button to set hours or the ªMº button to
set minutes. The time setting will increase each time you
press a button.
RADIO GENERAL INFORMATION
Radio Broadcast Signals
The radio will provide excellent reception under most
operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help

²Defrost/Floor
Air is directed through the windshield defrost
and the floor outlets. This setting works best in
cold or snowy conditions that require extra heat
at the windshield. This setting is good for maintaining
comfort while reducing moisture on the windshield.
²Defrost
Air is directed through the windshield defrost
outlet. Use this mode with maximum fan and
temperature settings for best windshield defrosting.
NOTE:The air conditioning compressor operates in this
mode. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, leave in the Defrost
mode only when necessary.
Air Conditioning Control
With the fan control in the ON position, push the
A/C button to turn on the air conditioning com-
pressor. An indicator light above the button shows
that the Air Conditioning compressor is on. Conditioned
air is now directed through the outlets selected. Pushing
the button a second time turns the compressor OFF.
Slight changes in engine speed or power may be noticed
when the compressor is on. This is a normal occurrence
since the compressor will cycle on and off to maintain
comfort and increase fuel economy.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects.

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to ªMaintenance Proceduresº in Section 7 of this manual
for proper coolant selection.
Winter Operation
²
Use the Defrost mode to direct cold air away from the
occupants during engine warm-up in cold weather.
²The blower air will heat faster in cold weather if you
use only the low blower speeds for the first ten
minutes of vehicle operation.
²Use of the air Recirculation mode during winter
months is not recommended because it may cause
window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.

130 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct any other occupant to buckle their seat
belt.WARNING!
²Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
injured seriously or fatally. Don't leave the keys in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
²Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
²Be sure to turn off the engine if you want to rest or
sleep in your car. Accidents can be caused by
inadvertently moving the gear selection lever or
by pressing the accelerator pedal. This may cause
excessive heat in the exhaust system, resulting in
overheating and vehicle fire, which may cause
serious or fatal injuries.
132 STARTING AND OPERATING

CAUTION!
Long periods of engine idling, especially at high
engine speeds, can cause excessive exhaust tempera-
tures, which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
Normal Starting
NOTE:
²You must disarm the security system in order to start
the engine. For details, refer to ªSecurity Alarm Sys-
temº in Section 2 of this manual
²Normal Starting of either a cold or a warm engine does
not require pumping or depressing the accelerator
pedal. However, if the engine has not started within 3
seconds, slightly depress the accelerator pedal while
continuing to crank. If the engine fails to start within
15 seconds, turn the key to the ªOFF/LOCKº position,
wait 5 seconds, then repeat the normal starting proce-
dure.
To start the engine:
1. Fully apply the parking brake.
2. Press the clutch pedal to the floor.
NOTE:The engine will not start unless the clutch pedal
is pressed to the floor.
3. Place the gear selector in NEUTRAL
4. Insert the ignition key fully into the ignition switch

134 STARTING AND OPERATING

If Engine Fails to Start
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
WARNING!
²Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to
start the vehicle. This could result in flash fire
causing serious personal injury.
²Do not attempt to push or tow your vehicle to get
it started. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite
and damage the converter and vehicle. If the
vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly, so
follow this procedure carefully. See section 6 of
this manual for jump starting instructions.
