Drive Belt — Check Condition
Check the drive belt condition. Refer to the “Maintenance
Schedule” in Section 8 of this manual.
Inspect the drive belt for evidence of cuts, cracks, or
glazing and replace the belt for any sign of damage
which could result in belt failure.
The belt is self-tensioning and will not need adjustment.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New spark plugs should be
installed at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Refer to “Fluids, Lubricants, and Genuine Parts” in
Section 8 for spark plug information.
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.
356 MAINTAINING YOUR VEHICLE

Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.WARNING!
•Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information Book for
further warranty information.
•The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced repairman.

steel belt traction on the drive and driven pulleys. Refer
to “Fluids, Lubricants and Genuine Parts” for correct
fluid type.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid will cause belt slip and
result in a complete transmission failure! Refer to
“Fluids, Lubricants, and Genuine Parts” for correct
fluid type.
Fluid Level Check
The fluid level in the automatic transaxle should be
checked only by a trained technician.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” in Section 8 of this
manual for the correct change interval.
Special Additives
Do not add any materials (other than leak detection dyes)
to Continuously Variable Transaxle (CVT) Fluid
(CVTF+4). CVTF+4 is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Manual Transaxle
Lubricant Selection
Use only the manufacturers recommended transmission
fluid. Refer to “Fluids, Lubricants, and Genuine Parts”
under Section 8.
Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more that 3/16 in (4.7 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the proper level.

Instrument Panel Bezels
CAUTION!
When installing hanging air fresheners in your ve-
hicle, read the installation instructions carefully.
Some air fresheners will damage the finish of
painted or decorated parts if allowed to directly
contact any surface.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet, soft rag. A mild soap solution may
be used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean, damp
rag.2. Dry with a soft cloth.
Seat Belt Maintenance
Do not bleach, dye or clean the seat belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage can also weaken the fabric.
If the seat belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the seat belts from the
car to wash them.
Replace the seat belts if they appear frayed or worn or if
the buckles do not work properly.
Dry with a soft cloth.
