10-72 Vehicle Care
Jump Starting the Volt
If the Volt won't start, the 12 volt
battery may be run down. To jump
start the Volt use the underhood
remote positive (+) and negative ( )
terminals.
1. The other vehicle used to jump
start the Volt must have a 12 volt
battery with a negative ground
system.
Notice: Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged.
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 N (Neutral) and set the
parking brake.
Notice: If the radio or other
accessories are left on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories when
jump starting the vehicle.
3. Turn off the ignition 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.
4. Locate the positive (+) and
negative ( ) terminals on the
other vehicle.
5. Open the hood to locate the
positive (+) and negative ( )
terminals on your Volt. Open the
access cover (A) for the remote
positive (+) terminal. The remote
negative terminal (B) for the
Volt is a stud marked GND ( )
on the driver side of the engine
compartment.
