Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if exhaust fumes can be detected inside the vehicle; or
when the underside or rear of the vehicle is damaged;
have a competent mechanic inspect the complete exhaust
system and adjacent body areas for broken, damaged,
deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep
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!
•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 temperature con-
trolled and 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 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.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 engine
188 MAINTAINING YOUR VEHICLE

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 manufacturer’s recommended coolant. Re-
fer to the Recommended Fluids, Lubricants and Genuine
Parts section for the 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.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.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With theengine 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 accumulat-
ing on the radiator and being vaporized when the
thermostat opens, allowing hot water to enter the radia-
tor.
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.
•Maintain 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.

NOTE:Often, fluids such as oil, power steering fluid, and
brake fluid are used during assembly plant operations to
ease the assembly of hoses to couplings. Therefore, oil
wetness at the hose-coupling area is not necessarily an
indication of leakage. Actual dripping of hot fluid when
systems are under pressure (during vehicle operation)
should be noted before hose is replaced based on leakage.
NOTE:Inspection of brake hoses should be done
whenever the brake system is serviced and every engine
oil change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning lamp shows system failure.Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However, low
fluid level may be caused by a leak and a checkup may be
needed.
Use only the manufacturer’s recommended brake fluid.
Refer to the Recommended Fluids, Lubricants and Genu-
ine Parts section for correct fluid type.

Procedure For Checking Fluid Level
To properly check the automatic transaxle fluid level, the
following procedure must be used:
•The vehicle must be on level ground.
•The engine should be running at curb idle speed for a
minimum of 60 seconds.
•Fully apply parking brake.
•Place the gear selector momentarily in each gear
position ending with the lever in P (PARK).
•Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
•If the fluid is hot(180° F / 82° C), the reading should
be in the cross hatched area marked ”HOT” (between
the upper two holes in the dipstick).
•If the fluid is cold(80° F / 27° C), the reading should
be in the cross hatched area marked “COLD” (between
the lower two holes in the dipstick).
•If the fluid level shows low, add sufficient transmis-
sion fluid to bring to the proper level.3.5L Transmission Dipstick

Underhood Fuses
A Power Distribution center is located in the engine
compartment. This center contains fuses and relays for
circuits that operate only under the hood. A label which
identifies these components is located on the underside
of the cover.CAUTION!
When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
