N (Neutral):In this position, the
propulsion system does not connect
with the wheels.
D (Drive): This position is for
normal driving. It provides the
best fuel economy. If more power
is needed for passing, and the
vehicle is:
.Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 56 km/h (35 mph)
or more, push the accelerator
all the way down.
Notice: If the vehicle seems to
accelerate slowly or not respond
when you go faster, and you
continue to drive the vehicle
that way, you could damage
the electric drive unit. Have the
vehicle serviced right away. L (Low):
This position reduces
vehicle speed without using the
brakes. You can use L (Low) on
hills. It can help control vehicle
speed going down steep mountain
roads along with using the brakes
off and on. You can use L (Low)
on very steep hills, in deep snow,
or in mud.
Notice: Spinning the tires or
holding the vehicle in one
place on a hill using only the
accelerator pedal may damage
the electric drive unit. The repair
will not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When propulsion is active and
the vehicle begins to drive away,
ABS checks itself. A momentary
motor or clicking noise might be
heard while this test is going on,
and it might even be noticed that
the brake pedal moves a little.
This is normal.

Black plate (34,1)Chevrolet Volt Owner Manual - 2011
9-34 Driving and Operating
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5‑26.
If driving safely on a wet road
and it becomes necessary to
slam on the brakes and continue
braking to avoid a sudden obstacle,
a computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel. ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

To apply the EPB when this
light is on, lift up on the
Yswitch
and hold it in the up position.
Full application of the parking brake
by the EPB system may take a
longer period of time than normal
when this light is on. Continue to
hold the
Yswitch until the Electric
Parking Brake Light remains on.
If the Service Electric Parking
Brake Light is on, see your dealer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
For maximum EPB force when
parking on a hill, pull the EPB
switch twice.
EPB Release
To release the EPB, place the
vehicle in ON/RUN, apply and hold
the brake pedal, and push down
momentarily on the
Yswitch.
If attempting to release the EPB
without the brake pedal applied,
a chime will sound, and the DIC
message STEP ON BRAKE TO
RELEASE PARK BRAKE will be
displayed. The EPB is released
when the Electric Parking Brake
Light is off.
If the Service Electric Parking
Brake Light is on, the EPB has
detected a system problem, and is
operating with reduced functionality.
To release the EPB when this light
is on, push down on the
Yswitch
and hold it in the down position.
EPB release may take a longer
period of time than normal when
this light is on. Continue to hold
the
Yswitch until the Electric
Parking Brake Light is off. If the
light is on, see your dealer. Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
Electric Parking Brake Light is
off before driving.
Automatic EPB Release
The EPB will automatically release
if the vehicle is running, placed
into gear, and an attempt is
made to drive away. Avoid rapid
acceleration when the EPB is
applied, to preserve parking
brake lining life.

page 5‑25, Service Electric Parking
Brake Light on page 5‑25, and
Brake System Messages on
page 5‑46.

2. When the READY TO REFUELmessage displays, the fuel
door on the passenger side will
unlock. Push the rearward edge
of the fuel door in and release
to open the door.
3. Turn the fuel cap counterclockwise to remove.
While refueling, hang the fuel
cap tether from the hook on
the inside of the fuel door.
Complete refueling within
30 minutes of pushing the
fuel door button found on the
driver side door. If refueling
more than 30 minutes, push
the fuel door button again. 4. After refueling, reinstall the fuel
cap by turning it clockwise until it
clicks. Close the fuel door.
{WARNING
Fuel can spray out on you
if you open the fuel cap too
quickly. If you spill fuel and then
something ignites it, you could
be badly burned. This spray can
happen if the tank is nearly full,
and is more likely in hot weather.
Open the fuel cap slowly and
wait for any hiss noise to stop.
Then unscrew the cap all the way.
Do not top off or overfill the tank and
wait a few seconds before removing
the nozzle. Clean fuel from painted
surfaces as soon as possible.
See Exterior Care on page 10‑89.
{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.
Notice: 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 might
not fit properly, might cause
the malfunction indicator lamp
to light, and could damage the
fuel tank and emissions system.
