damage and proper alignment.
Belt replacement on some models requires the use of special
tools,
we recommend having your vehicle serviced at an
authorized dealer.
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
f
lammab

proved refrigerants or lubricants can cause the system
t
o fail,
requiring costly repairs. Refer to Warranty Infor-
mation Book, located in your owner’s information kit,

The air conditioning system contains refrigerant under
high pr
essure. 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 technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system a
s the chemicals can damage your air
conditioning components. Such damage is not covered
by the New Vehicle Limited Warranty.
