4. After refueling, reinstall the fuelcap by turning it clockwise until
it clicks. Close the fuel door.
{Warning
Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:
. Vehicle performance issues,
including engine stalling and
damage to the fuel system.
. Fuel spills.
. Potential fuel fires.
Be careful not to spill fuel. Wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care 0315.
{Warning
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Caution
If a new fuel cap is needed, be
sure to get the right type of cap
from your dealer. The wrong type
of fuel cap may not fit properly,
may cause the malfunction
indicator lamp to light, and could
damage the fuel tank and
emissions system. See
Malfunction Indicator Lamp
(Check Engine Light) 0114.
Filling a Portable Fuel
Container
{Warning
Filling a portable fuel container
while it is in the vehicle can cause
fuel vapors that can ignite either
by static electricity or other
means. You or others could be
badly burned and the vehicle

. Use approved fuel
containers.
. Remove the container from
the vehicle, trunk, or pickup
bed before filling.

fill opening of the container
before dispensing fuel, and
keep it in contact with the fill
opening until filling is
complete.

310 Vehicle Care
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 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 12-volt battery
is under the load floor 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 ground 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.
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.
Connecting the Jumper Cables 1. Connect the red positive (+) jumper cable to the positive (+)
terminal of the other vehicle
with the run-down battery. Use
a remote positive (+) terminal if
available. Do not let the other
end touch metal.

Service and Maintenance 333
.To avoid break-down or failure to
start the vehicle, maintain a
battery with full cranking power.
. Trained dealer technicians have
the diagnostic equipment to test
the battery and ensure that the
connections and cables are
corrosion-free.
Belts
. Belts may need replacing if they
squeak or show signs of
cracking or splitting.
. Trained dealer technicians have
access to tools and equipment
to inspect the belts and
recommend adjustment or
replacement when necessary.
Brakes
Brakes stop the vehicle and are
crucial to safe driving.
. Signs of brake wear may include
chirping, grinding, or squealing
noises, or difficulty stopping. .
Trained dealer technicians have
access to tools and equipment
to inspect the brakes and
recommend quality parts
engineered for the vehicle.
Fluids
Proper fluid levels and approved
fluids protect the vehicle’s systems
and components. See
Recommended Fluids and
Lubricants 0335 for GM approved
fluids.
. Engine oil and windshield
washer fluid levels should be
checked at every fuel fill.
. Instrument cluster lights may
come on to indicate that fluids
may be low and need to be
filled.
Hoses
Hoses transport fluids and should
be regularly inspected to ensure
that there are no cracks or leaks.
With a multi-point inspection, your
dealer can inspect the hoses and
advise if replacement is needed. Lamps
Properly working headlamps,
taillamps, and brake lamps are
important to see and be seen on
the road.
.
Signs that the headlamps need
attention include dimming, failure
to light, cracking, or damage.
The brake lamps need to be
checked periodically to ensure
that they light when braking.
. With a multi-point inspection,
your dealer can check the lamps
and note any concerns.
Shocks and Struts
Shocks and struts help aid in control
for a smoother ride.
. Signs of wear may include
steering wheel vibration, bounce/
sway while braking, longer
stopping distance, or uneven
tire wear.
. As part of the multi-point
inspection, trained dealer
technicians can visually inspect
the shocks and struts for signs
