CAUTION!
If the negative battery cables are not isolated properly it
can cause a potential power spike or surge in the system,
resulting in damage to essential electrical components.
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 battery.
• If your vehicle is equipped with Stop/Start system then
disconnect 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
and high blower setting. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again.
• If assistance is needed to disconnect the battery system, see
your authorized dealer.
