JUMP-STARTING THE BATTERY
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.
CAUTION!
Do not try to push or tow your vehicle to get it
started. Your vehicle cannot be started this way.
Pushing with another vehicle may damage the trans-
axle or the rear of your vehicle. If your vehicle has a
discharged (dead) battery, booster cables may be
used to obtain a start from another vehicle. This type
of start can be dangerous if done improperly, so
follow the procedure carefully.
WARNING!
Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or clothing.
Don’t lean over battery when attaching clamps or
allow the clamps to touch each other. If acid splashes
in eyes or on skin, flush the contaminated area
immediately with large quantities of water.
A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes. Do not use a booster battery or
any other booster source with an output that exceeds
12 volts.
NOTE:The battery is stored in a compartment in front
of the tire in the right front fender and is accessible
through the engine compartment. The tire and wheel
need not be removed to gain access to the battery.

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!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition key
to the OFF position. The fan is controlled by
engine coolant temperature and Air Conditioning
pressure. It can start at any time the ignition key is
in the ON position.
•You 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 or coolant bottle is hot.
Coolant Checks
Check coolant protection every 12 months (before the
onset of freezing weather, where applicable). If the cool-
ant is dirty or rusty in appearance, the system should be
drained, flushed and refilled with fresh coolant.
214 MAINTAINING YOUR VEHICLE

Check the front of the radiator and condenser for any
accumulation of bugs, leaves, etc. Clean the radiator and
condenser by gently spraying water from a garden hose
at the back of the core.
Check the engine cooling system hoses for condition and
tightness of connection. Inspect the entire system for
leaks. Any hoses that show cuts or severe abrasion must
be replaced.
Cooling System — Drain, Flush and Refill
At the intervals shown on the Maintenance Schedules (5
years/100,000 miles), 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.
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 enginecoolant 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 manufacturer’s recommended coolant. Re-
fer to the Recommended Fluids, Lubricants and Genuine
Parts section for correct coolant type.
CAUTION!
Failure to use the proper antifreeze could cause
radiator plugging and engine overheating. Do not
mix antifreeze brands or types. Do not use plain
water alone or alcohol base antifreeze products. Do
not use additional rust inhibitors or antirust prod-
ucts, as they may not be compatible with the radiator
coolant and may plug the radiator.
Adding Coolant
When adding coolant, a minimum solution of 50% eth-
ylene glycol antifreeze coolant in water should be used.
MAINTAINING YOUR VEHICLE 215

Higher concentrations (not to exceed 70%) may be used if
temperatures below -37°F (-38°C) 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.
NOTE:Mixing coolant types will decrease the life of the
engine coolant and will require more frequent engine
coolant changes.
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.
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.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
The warning words “DO NOT OPEN HOT” 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 over-
heated 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.
WARNING!
Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or engine
damage may result.
216 MAINTAINING YOUR VEHICLE

Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine Off and cold, the level of the coolant in the bottle
should be between the MIN and MAX cold fill lines.
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 of
the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulating
on the radiator and being vaporized when the thermostat
opens, allowing hot water to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant bottle.
•Check coolant freeze point in the system.
•If frequent coolant additions are required, or if the
level in the recovery bottle does not drop when the
engine cools, the cooling system should be pressure
tested for leaks.
MAINTAINING YOUR VEHICLE 217

•Maintain a coolant concentration of a minimum of 50%
ethylene glycol and high quality water with recom-
mended antifreeze for proper corrosion protection of
your engine cooling system that contains aluminum
components.
•Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
•Keep the front of the radiator and air conditioning
condenser clean.
•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps
and couplings to make sure they are secure and no leaks
are present. Components should be replaced immedi-
ately if there is any evidence of degradation that could
cause failure.
Brakes
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in Section 8,
Maintenance Schedules.
