10-56 Vehicle Care
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 earth 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.
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 the vehicle.
3. Turn off both vehicles. 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
vehicle with the run-down
battery.
5. Locate the positive (+) and
negative (-) battery terminals on
the Volt. The access cover is
under the load floor access
cover in the rear cargo area.
Open the access covers for the
positive (+) terminal (1) and the
negative ( ) terminal (2).
6. Check that the jumper cables do
not have loose or missing
insulation or a shock could result
and the vehicles could 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 remote negative (-) terminal if
available, or a heavy, unpainted
metal engine part or a solid
engine earth on the vehicle with
the run-down battery.
Do not connect positive (+) to
negative (-) or there will be a
short that may damage the
battery or other parts of the
vehicle. Do not connect the
negative (-) cable to the
negative (-) terminal on the
run-down battery because this
can cause sparks.
