• Check the SOC of the LV battery once a week using the wiTECH diagnosis equipment.
Remember that the vehicle will not wake up automatically if the vehicle was not switched to key
on during the 24 hours prior to the programmed wake up time.
CAUTION! It is recommended to strictly observe the above instructions to avoid problems
due to the vehicle battery discharging too much.
WARNING! Indications below needed only if necessary to recharge the 12V battery with an
external charger.
Before charging the 12V battery, disconnect any charging devices and the
diagnosis equipment (if connected), open the driver’s door and fully roll down
the window, turn the key or set the starter button to OFF. Remove the key and
put it in a safe location away from the vehicle, close the driver side door, wait 5
minutes. Refer to the detailed service procedures available in DealerConnect>
Service Library under: Service Info>08 - Electrical / 8F - Engine Systems / Battery
