NOTE:Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent coolant changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze) and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery bottle.
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 pre-
caution. Never add engine coolant (antifreeze)
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.
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
396 MAINTAINING YOUR VEHICLE

rules for your community. To prevent ingestion by ani-
mals or children do not store ethylene glycol-based
engine coolant (antifreeze) in open containers or allow it
to remain in puddles on the ground. If ingested by a child
or pet, seek emergency assistance immediately. Clean up
any ground spills immediately.
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 engine coolant (antifreeze) in the
bottle should be between the “ADD” and “FULL” lines
shown on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
the coolant freeze point or replacing the engine coolant
(antifreeze). Advise your service attendant of this. Aslong as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant (antifreeze) 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/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) 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 recovery bottle.

MAINTAINING YOUR VEHICLE 397

•Check the coolant freeze point in the radiator and in
the coolant recovery bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
recovery bottle must also be protected against freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine which contains aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
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 coolant (antifreeze) per-
formance, poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to “Maintenance Schedule” for further information.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.

fluid which has been formulated with special metal to
metal friction coefficient additives to provide the proper
steel belt traction on the drive and driven pulleys. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid will cause belt slip and
result in a complete transaxle failure! Refer to “Flu-
ids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
Fluid Level Check
The fluid level in the automatic transaxle should be
checked only by a trained technician.
Fluid And Filter Changes
Refer to “Maintenance Schedule” for further information.
Special Additives
Do not add any materials (other than leak detection dyes)
to Continuously Variable Transaxle (CVT) Fluid
(CVTF+4). CVTF+4is an engineered product and its
performance may be impaired by supplemental addi-
tives.
CAUTION!
Do not use chemical flushes in your transaxle as the
chemicals can damage your transaxle components.
Such damage is not covered by the New Vehicle
Limited Warranty.
Manual Transaxle – If Equipped
Lubricant Selection
Use only the manufacturers recommended transmission
fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.

NOTE:
•The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle’s
oil if it has been six months since your last oil change
and even if the oil change indicator message is NOT
illuminated.
•Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•Under no circumstances should oil change intervals
exceed 6,000 miles (10 000 km) or six months, which-
ever comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If this
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by referring to the steps described under “Electronic Vehicle
Information Center/Engine Oil Change Indicator
System/Oil Change Required” in “Understanding Your
Instrument Panel” or under “Instrument Cluster
Description/Odometer/Trip Odometer” in “Under-
standing Your Instrument Panel” for further information.
At Each Stop for Fuel
•Check the engine oil level about five minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.

•Check the tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of the coolant reservoir, brake
master cylinder, and power steering — add as needed.
•Check all lights and other electrical items for correct
operation.At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
•Check the manual transaxle fluid level.
