If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to minimize
the drain on your vehicle's battery:
• Disconnect the negative cable from the battery.
• If yo
ur vehicle is equipped with Stop/Start system then
disc
onnect both the main and supplemental negative
battery cables.
• Any time you store your vehicle or keep it out of service
(i.e
., vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh air

lubrication to minimize the possibility of compressor
damage when the system is started again.
