Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% ethylene glycol antifreeze coolant and
50% water is recommended. Refer to “Maintenance Pro-
cedures” in “Maintaining Your Vehicle” for proper cool-
ant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “MaintenanceProcedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes, in
fresh air with the blower setting on high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
