10-26 Vehicle Care
Refer to the replacement number
shown on the original battery label
when a new 12‐volt battery is
needed. The vehicle has an
Absorbed Glass Mat (AGM) 12‐volt
battery. Installation of a standard
12‐volt battery will result in reduced
12‐volt battery life.
When using a 12‐volt battery
charger on the 12‐volt AGM battery,
some chargers have an AGM
battery setting on the charger.
If available, use the AGM setting on
the charger, to limit charge voltage
to 14.8 volts.
{WARNING
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
Vehicle Storage
{WARNING
12‐volt batteries have acid that
can burn you and gas that can
explode. You can be badly hurt if
you are not careful. SeeJump
Starting on page 10‑75 for tips on
working around a battery without
getting hurt.
Extended Storage
Remove the 12‐volt battery black,
negative (−) cable from the battery
to keep the 12‐volt battery from
running down or use a battery trickle
charger. In addition, to avoid potential
damage to the high voltage battery,
perform the following recommended
steps:.Store the high voltage battery
with 1/2 charge or less.
.Always store the vehicle in an
environment between
−10°C
(14°F) and 30°C (86°F).
.Vehicle storage at extreme
temperatures can cause damage
to the high voltage battery.
Remember to reconnect the 12‐volt
battery when ready to drive 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. The other vehicle used to jumpstart 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 Neutral and set the parking
brake.
Notice: 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 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 thepositive (+) 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.

Disconnecting the Jumper Cables
1. Disconnect the blacknegative (−) jumper cable from
the Volt. Do not let the other end
of the cable touch anything until
after the next step.
2. Disconnect the black negative (−) jumper cable from
the other vehicle with the good
battery.
3. Disconnect the red positive (+) jumper cable from the other
vehicle. Do not let the other end
of the cable touch anything until
after the next step.
4. Disconnect the red positive (+) jumper cable from the Volt.
5. Return the positive (+) and negative (−) terminal covers to
their original positions.Jump Starting Another Vehicle
When using the Volt to jump start
another vehicle with a run‐down
battery, jumper cables are
connected directly to the positive (+)
and negative (−) terminals on the
12‐volt battery in the rear cargo
area. Do not use the remote
terminals under the hood. This
could cause a fuse to overload in
the Volt.
1. Check the other vehicle. It 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 Neutral and set the parking
brake.
Notice: 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.
