Jeep WRANGLER 2020 Owner's Manual page 539

CAUTION! (Continued)
Do not drive for a prolonged period on dry

pavement.
Observe the traction device manufacturer's

instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed
of the device manufacturer's if it is less
than 30 mph (48 km/h).
Do not use traction devices on a compact

spare tire.
STORING THE VEHICLE
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 Equip-
ment (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

electrical 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 lubrication 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 when-

ever possible.
SERVICING AND MAINTENANCE
NOTE:
The hybrid has a feature of periodic wake-up
that occurs every 3 weeks. This feature charges
the 12 Volt battery from the HV Battery. This will
happen as long as the HV Battery remains
above the minimum state of charge Ú page 40.
CAUTION!
Before removal of the positive and negative
terminals to the battery, wait at least a
minute with ignition switch in the OFF position
and close the driver's door. When
reconnecting the positive and negative
terminals to the battery be sure the ignition
switch is in the OFF position and the driver's
door is closed.
