²Anytime 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 the fresh air and high blower setting. This willinsure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
