STORING THE VEHICLE

WARNING!
Take care to avoid the radiator cooling fan

whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
Remove any metal jewelry such as rings,

watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
Vehicles with the Stop/Start system will be

equipped with two batteries. Both the main
and the supplemental batteries must be
disconnected to completely de-energize the
12 Volt electrical system.
Serious injury or death could result if you do

not disconnect both batteries. To learn how
to properly disconnect, see your authorized
dealer.
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 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.
If assistance is needed to disconnect the

battery system, see your authorized dealer.
