Jump Starting
Jump Starting - North
America
Jump starting is connecting jumper
cables between the two vehicles to
enable vehicle starting. If the Volt or
another vehicle has a run-down
12-volt battery, it can be jump
started using good condition jumper
cables. There are different
procedures depending on if the Volt
has a run-down battery or another
vehicle has a run-down battery.
Read the appropriate procedures
that follow.
{Warning
The high voltage battery cannot
be jump started either with
another vehicle or battery
charger. Personal injury, death,
or damage to the vehicle could
result.
{Warning
WARNING:Battery posts,
terminals, and related
accessories contain lead and lead
compounds, chemicals known to
the State of California to cause

the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
Jump Starting the Volt
If the Volt will not start, the 12-volt
battery may be run down. To jump
start the Volt use the underhood
remote positive (+) and negative (−)
terminals.
1. Remote Positive (+)Terminal
2. Remote Negative (−) Terminal
1. The other vehicle used to jump start the Volt must have a
12-volt battery with a negative
ground system.
Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Park both vehicles close enough so that the jumper
cables can reach both vehicles'
positive (+) and negative (−)
terminals. The vehicles must
not touch each other. It could
cause an unwanted ground
connection that could damage
both vehicles' electrical
systems. Put both vehicles in P (Park)
for an automatic transmission
or electric drive unit. For a
manual transmission, place the
vehicle in Neutral and set the
parking brake.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn the ignition off on the other vehicle. Turn off the
radio, all lamps, and
accessories that are not
needed in both vehicles.
Unplug accessories from the
cigarette lighter or the
accessory power outlets. This
avoids sparks and helps save
both batteries and accessories.

be damaged.
Before connecting the jumper
cables, here are some basic
things to know. Positive (+)
jumper cable goes to
positive (+) battery terminal or
a remote positive (+) terminal if
available. Negative (−) jumper
cable goes to negative (−)
battery terminal or a remote
negative (−) terminal if
available. Do not connect
positive (+) to negative (−) or there will be a short that may
damage the battery and other
parts of the vehicle.
Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.
