Air Conditioner Maintenance - Dodge Ram 3500 Owner's Manual

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
vehicle, disconnect both vehicle battery cables
before connecting the charger to battery. Do not
use a "fast charger" to provide starting voltage.
MAINTAINING YOUR VEHICLE
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized Mopar 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.
