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 nega-
tive post. Battery posts are marked posi-
tive (+) and negative (-) and are identi-
fied on the battery case. Cable clamps
should be tight on the terminal posts
and free of corrosion.
If a “fast charger” is used while the
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 volt-
age.
DEALER SERVICE
An authorized dealer has the qualified service
personnel, special tools, and equipment to
perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals be-
fore attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could
result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or
around a motor vehicle. Only do service
work for which you have the knowledge
and the proper equipment. If you have any
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
Air Conditioner Maintenance
For best possible performance, your air con-
ditioner 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 manufac-
turer for your air conditioning system.
Some unapproved refrigerants are flam-
mable and can explode, injuring you.
Other unapproved refrigerants or lubri-
cants can cause the system to fail, re-
quiring costly repairs. Refer to Warranty
Information Book, located in your own-
er’s information kit, for further warranty
information.
The air conditioning system contains re-
frigerant 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 tech-
nician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
