JUMP STARTING — BEV MODELS
If your vehicle has a discharged battery, it can be jump
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump starting can be dangerous if done improp-
erly, so please follow the procedures in this section
carefully.
NOTE:
When using a portable battery booster pack, follow the
manufacturer’s operating instructions and precautions.
The vehicle requires its 12 Volt battery power to turn-on
the vehicle's high voltage battery. The high voltage bat-
tery is used to charge the 12 Volt battery, provide elec-
tric vehicle operation. If the 12 Volt battery has been
discharged, the vehicle can be jump started using a set
of jumper cables and a battery in another vehicle or by
using a portable battery booster pack.
If the vehicle's high voltage battery has also been dis-
charged, it will need to be recharged to a minimum
operating State Of Charge (SOC) before the vehicle can
be operated:
•
If the vehicle can be connected to a Level 1 or Level
2 charger where it is currently parked, the vehicle
will still require a jump start to allow the vehicle to
begin the battery charging process. Once the vehicle
charging has begun (indicated by the charge status
indicator on top of the vehicle's instrument panel),
the jumper cables can be removed from the vehicle
jump posts.
•
If the vehicle cannot be connected to a Level 1 or
Level 2 charger where it is currently parked, the
vehicle can be moved by connecting 12 Volt power
to the vehicle's jump posts and then shifting the
transmission from PARK (P) into NEUTRAL (N).
Power provided by the jumper cables will also allow
the Electric Park Brake to be released. Carefully
move the vehicle to a Level 1 or Level 2 charge loca-
tion. While the vehicle is being moved, the external
12 Volt power must remain connected to the vehicle
jump posts.
NOTE:
Be careful when moving the vehicle - ensure that con-
trol of the vehicle is maintained. Also, ensure that
vehicle is secured to prevent unintentional movement
during and after moving the vehicle. If the external
12 Volt power becomes disconnected from the vehicle
jump posts or there is an interruption of the 12 Volt
power while moving the vehicle, the vehicle's transmis-
sion may engage PARK. Do not allow the jumper cables
to come in contact with each other or to the vehicle,
this will result in a short.
When the vehicle is at the charging location, shift the
transmission back to PARK, apply the Electric Park
Brake, and start the high voltage battery charging. Once
the vehicle has been secured against unintentional
movement and high voltage battery charging has been
initiated, the jumper cables can be removed from the
vehicle jump posts.
WARNING!
Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
