The 12 volt battery is discharged
When the 12 volt battery is discharged, the ve‐
hicle electrical system is no longer supplied with
electricity. The external start procedure sup‐
plies power to the vehicle electrical system and
the vehicle can be started.
High-voltage battery discharged
When the high-voltage battery is discharged,
the vehicle cannot be started. The external start

compartment acts as the battery's positive ter‐
minal.
