CAUTION!
• It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post, and the negative cable is attached to
the negative post. Battery posts are marked (+)
positive and (-) negative and identified on the
battery case.
• If a “fast charger” is used while battery is in the
vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do
not use a “fast charger” to provide starting voltage.
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 condition should also be checked at this
time.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.
