348 SERVICING AND MAINTENANCE
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.
Battery Cable Disconnect
NOTE:
You must isolate the supplemental battery
connection point, as well as the main battery
terminal from the post, as shown in the
image, to fully de-energize both batteries for
storage. If assistance is needed to discon-
nect the battery system, see your authorized
dealer.
Do not disconnect the Intelligent Battery
Sensor (IBS), or your Stop/Start system may
not function for up to 24 hours, due to the IBS
being set into learn mode.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according
to geographic locations and usage. Chemicals
that make roads passable in snow and ice and
those that are sprayed on trees and road
surfaces during other seasons are highly corro-
sive to the metal in your vehicle. Outside
parking, which exposes your vehicle to airborne
contaminants, road surfaces on which the
vehicle is operated, extreme hot or cold weather
and other extreme conditions will have an
adverse effect on paint, metal trim, and under-
body protection.
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.
