VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21 days, you may want to take these steps to protect your battery.
Disconnect the negative cable from the battery.
Anytime you store your vehicle, or keep it out of service (e.g., 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 will ensure adequate system lubrication to minimize the possibility of compressor damage when the system is started again.
