Air Conditioner Maintenance - Dodge 2009 Challenger Owner's Manual

378 MAINTAINING YOUR VEHICLE
WARNING! (Continued)
The battery in this vehicle has a vent hose that
should not be disconnected and should only be
replaced with a battery of the same type (vented).
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 posi-
tive (+) and negative (-) and are identified 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 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 tension 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.
