Tesla Model S: If Vehicle Has No Power

If Model S has no low voltage power, perform the following steps to open the hood or jump start the auxiliary low voltage battery.

Jump Starting the Low Voltage Battery

CAUTION: Model S cannot be used to jump start another vehicle. Doing so can result in damage.

NOTE: If jump starting Model S using another vehicle, refer to that vehicle manufacturer's instructions. The following instructions assume an external low voltage power supply (such as a portable jump starter) is used.

CAUTION: Avoid short circuits when jump starting Model S. Connecting cables to the wrong jump post, touching leads together, etc., can result in damage to Model S.

1. Open the hood.

2. Remove the maintenance panel by pulling it upwards to release the trim clips that hold it in place.
