STORING THE VEHICLE
If you are storing your vehicle for more than
three weeks, 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 an authorized dealer.
Battery Cable Disconnect
CAUTION!
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
in tire size can cause damage to the transfer
case. Tire rotation schedule should be
followed to balance tire wear.
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 an 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.
