SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.
If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.
To avoid drawing exhaust gases into the vehicle, close the
trunk while driving. However, if for some reason it mustremain open, close all windows. Adjust the heating or
cooling system to force outside air into the vehicle. Set
the blower at high speed.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (bent retractor, torn
webbing, etc.). If there is any question regarding belt or
retractor condition, replace the belt.
Airbag Light
The light should come on and remain on for 6 to
8 seconds as a bulb check when the ignition
switch is first turned to ON/RUN. If the bulb is
not lit during starting, have it replaced. If the light stays
on or comes on while driving, have the system checked
by an authorized dealer.

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

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.

NOTE:The spare tire well is designed to hold the
compact spare tire or a deflated (flat) tire. A fully inflated
tire will not fit in the spare tire well.
JUMP-STARTING PROCEDURES IF BATTERY IS
LOW
WARNING!
Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is on. You can be hurt by the fan.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
axle cannot be started this way. 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 another vehicle.
This type of start can be dangerous if done improp-
erly, so follow this procedure carefully.
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.
2. When boosting from a battery in another vehicle, park
that vehicle within booster cable reach but without
letting the vehicles touch. Set parking brake, place auto-
matic transaxle in PARK (manual transaxle in NEU-
TRAL) and turn ignition to OFF for both vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads.

into the passenger compartment. In addition, inspect the
exhaust system each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide which is colorless and odorless. Breathing
it can make you unconscious and can eventually
poison you. Follow the above precautions to keep
your exhaust system as safe as possible.
Cooling System
WARNING!
²When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition key
to the OFF position. The fan is temperature con-
trolled and can start at any time the ignition key is
in the ON position.
²You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, don't open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator is hot.
Coolant Checks
Check coolant protection every 12 months (before the
onset of freezing weather, where applicable). If coolant is
dirty or rusty in appearance, the system should be
drained, flushed and refilled with fresh coolant.
180 MAINTAINING YOUR VEHICLE

Check the front of the radiator for an accumulation of
bugs, leaves, etc. Clean the radiator by gently spraying
water from a garden hose at the back of the core.
Check the recovery bottle tank tubing for condition and
tightness of connection at the bottle and radiator. Inspect
the entire system for leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing
properly, the coolant will begin to drain from the reserve
tank. Do not remove the cap when the cooling system is
hot.
Cooling System Ð Drain, Flush and Refill
At the intervals shown on the Maintenance Schedules,
the system should be drained, flushed and refilled.
If the solution is dirty and contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner. Follow with a thorough rinsing to
remove all deposits and chemicals. Discard oil antifreeze
solution.
Engine Coolant Disposal
Used ethylene glycol based engine coolant is a regulated
substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. Do not store ethylene glycol based engine
coolant in open containers or allow it to remain in
puddles on the ground. Prevent ingestion by animals or
children. If ingested by a child, contact a physician
immediately.
Selection Of Coolant
Use only the manufacturers recommended coolant, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct coolant type.
MAINTAINING YOUR VEHICLE 181

CAUTION!
Mixing of coolants other than specified (non-
HOAT), may result in engine damage that may not
be covered under the new vehicle warranty, and
decreased corrosion protection. If a non-HOAT cool-
ant is introduced into the cooling system in an
emergency, it should be replaced with the specified
coolant as soon as possible.
Do not use plain water alone or alcohol base anti-
freeze products. Do not use additional rust inhibi-
tors or antirust products, as they may not be compat-
ible with the radiator coolant and may plug the
radiator.
This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
Glycol based coolants is not recommended.
Adding Coolant
When adding coolant, a minimum solution of 50% eth-
ylene glycol antifreeze coolant in water should be used.
Use higher concentrations (not to exceed 70%) if tempera-
tures below ±34ÉF (-37ÉC) are anticipated.
Use only high purity water such as distilled or deionized
water when mixing the water/antifreeze solution. The
use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
Please note that it is the owner's responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:Mixing coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant reserve tank.
182 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
