Jeep WRANGLER 2023 Manual page 83

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

electrical system, check the battery charge
every 30 days.
Whenever you leave the vehicle stationary for

two weeks or more, idle the vehicle for approxi-
mately five minutes, with the air conditioning
system on and high fan speed. This will ensure
proper lubrication of the system, thus mini-
mizing 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.
SERVICING AND MAINTENANCE
NOTE:
The hybrid has a feature of periodic wake-up that
occurs every three 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 47.
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.
