correct mileage that the vehicle has been driven. There-
fore, if the odometer reading changes during repair or
replacement, be sure to keep a record of the reading
before and after the service so the correct mileage can be
determined.
19. Door Ajar Indicator
This vacuum fluorescent display indicator illuminates
when a door is not completely closed. If the door is open
for more than 8 minutes and the ignition key is in the
OFF position, the indicator will turn off.
20. Trip Indicator
This light will illuminate when the Trip Odometer is in
use.
21. Cruise Light Ð If Equipped
This indicator shows that the Speed Control
System is ON.
NOTE:
The word ªSETºwill notilluminate when the
Speed Control System is on.
22. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading between the lightblue and red areas of the gauge shows that the engine
cooling system is operating properly. The gauge
pointer may show a higher than normal temperature
when driving in hot weather, up mountain grades, in
heavy stop and go traffic, or when towing a trailer.
If the pointer rises to theH(red) mark, the instrument
cluster will sound a chime. Pull off the road at a safe area.
With the vehicle in Park, idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on theH(red)
mark, turn the ignition off immediately and call for
service.
There are steps that you can take to slow down an
impending overheat condition. If your air conditioning 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
control to maximum heat, the Mode control to Floor and
the Fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
82 UNDERSTANDING YOUR INSTRUMENT PANEL

Malfunction Indicator light to illuminate. The manufac-
turer recommends that you try a different brand of
unleaded gasoline having lower sulfur to determine if the
problem is fuel related prior to returning your vehicle to
an authorized dealer for service.
CAUTION!
If the Check Engine or Service Engine Soon light is
flashing, immediate service is required. See the On
Board Diagnostics paragraph in the Maintenance
section of this manual.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system, and could result
in loss of warranty coverage.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.

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 direc-
tional signals 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 action.
²On the highways Ð Slow down.
²In city traffic Ð While stopped, put transaxle in
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
control to maximum heat, the Mode control to floor, and
the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
152 WHAT TO DO IN EMERGENCIES

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads ªHº, pull
over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the ªHº, turn the engine off immediately, and call for
service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
JACKING AND TIRE CHANGING
WARNING!
²Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. Never start
or run the engine while the vehicle is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
²Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.

WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure
someone. Do not spin your vehicle's wheels faster
than 35 mph (55km/h) when you are stuck. And don't
let anyone near a spinning wheel, no matter what the
speed.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transaxle overheating and failure. It can
also damage the tires. Do not spin the wheels above
35 mph (55km/h).
TOWING A DISABLED VEHICLE
With Ignition Key
Four Speed Automatic Transaxle
Your vehicle may be towed under the following condi-
tions: The steering column must be unlocked and the
gear selector must be in NEUTRAL, the distance to be
towed must not exceed 100 miles (160 km), and the
towing speed must not exceed 44 mph (72 km/h). If the
transaxle is not operative, or if the vehicle is to be towed
more than 100 miles (160 km), the vehicle must be towed
with the front wheels off the ground to avoid damage to
the transaxle.
Manual Transaxle
Your vehicle may be towed if the gearshift lever is in
NEUTRAL. If the transaxle is not operative, the vehicle
must be towed with the front wheels off the ground.

Drive Belts Ð Check Condition and Tension
At the mileage shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specifications
and procedures shown in the Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Check the specifications section for the proper type
of spark plug for use in your vehicle.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
MAINTAINING YOUR VEHICLE 173

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturers specifica-
tions, should be obtained immediately.
To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected for prolonged period.
Engine Timing Belt
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Ignition Wiring System
The ignition cables should be kept clean and properly
connected. Terminals should be fully seated. Cracked,
damaged, or faulty cables should be replaced.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.
174 MAINTAINING YOUR VEHICLE

The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
The warning words ªDO NOT OPEN HOTº on the
cooling system pressure cap are a safety precaution.
never add coolant when the engine is overheated. Do
not loosen or remove the cap to cool an overheated
engine. Heat causes pressure to build up in the
cooling system. To prevent scalding or injury, do not
remove the pressure cap while the system is hot or
under pressure.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine idling, and warm to normal operating tempera-
ture, the level of the coolant in the bottle should be
between the ªFULLº and ªADDº marks.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking forcoolant freeze point or replacing coolant. Advise your
service attendant of this. As long as the engine operating
temperature is satisfactory, the coolant bottle need only
be checked once a month.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill.
Points to Remember
NOTE:
When the vehicle is stopped after a few miles of
operation, you may observe vapor coming from the front
