SERVICING AND MAINTENANCE
WARNING!
•
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 prop-
erly 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 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 ser-
vice (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
1 — Supplemental Negative Battery Cable
2 — Main Negative Battery Cable
3 — Main Negative Battery Terminal
4 — Intelligent Battery Sensor (IBS)
NOTE:
•
You must isolate the supplemental battery connec-
tion 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
disconnect the battery system, see an 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.
STORING THE VEHICLE — PHEV
(IF EQUIPPED)
If the vehicle should remain stationary for more than a
month, observe the following precautions:
•
Park your vehicle in a covered, dry and possibly airy
location with the windows open slightly.
•
Check that the parking brake is not engaged.
•
Disconnect the negative (-) terminal from the battery
post and be sure that the battery is fully charged.
During storage check battery charge quarterly.
NOTE:
Disconnecting the 12 Volt battery will prevent the
High Voltage (HV) battery from accepting a charge
from the Electric Vehicle Supply Equipment (EVSE).
Also, the vehicle will not condition the HV battery (if
needed and connected to a powered EVSE). If the
HV battery is not able to condition itself and it
becomes cold enough (or hot enough), the vehicle
will not start until the HV battery's cell temperatures
are between -22°F (-30°C) and 122°F (50°C).
•
If you do not disconnect the battery from the electri-
cal system, check the battery charge every 30 days.
•
Whenever you leave the vehicle stationary for two
weeks or more, idle the vehicle for approximately
five minutes, with the air conditioning system on
and high fan speed. This will ensure proper lubrica-
tion of the system, thus minimizing the possibility of
damage to the compressor when the vehicle is put
back into operation.
•
Plug in the vehicle when not using it whenever
possible.
