9. Important Additional Information
Do not attempt to jump start the high voltage battery, as it cannot be jump started. In case of full
discharge of the high voltage battery, the vehicle must be towed as mentioned on the previous
page.
In case the 12V auxiliary battery is discharged,
connect a starting device to the jump terminal
in the trunk as you would any 12V battery
(see image). Refer to the
“Emergency Starting”
section of the
Owner’s Manual for additional
information. Connect jumper cables in the order
shown in the image and disconnect in reverse order.
