Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored
back into the high voltage battery
system, contributing to increased
energy efficiency.
The hydraulic disc brakes work with
the regenerative braking to ensure
effective braking, such as when a
high braking demand is requested.
The braking system is
computer controlled and
blends the regenerative braking
with the conventional hydraulic disc
brakes to meet any requirements
for deceleration. The controllerinterprets the braking request
and uses regenerative braking,
conventional hydraulic braking, or a
combination of both as necessary.
Because the controller applies the
hydraulic brakes through its high
pressure accumulator, you may
occasionally hear the motor‐driven
pump when it recharges the system.
This is normal.
See
Warning Lights, Gauges,
and Indicators on page 5‑9 and
Driver Information Center (DIC) on
page 5‑43. In the event of a
controller problem, the brake pedal
may be harder to push and the
stopping distance may be longer.
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel
spin. The system operates if it
senses that one or both of the drive
wheels are spinning or beginning to
lose traction. When this happens,
the system brakes the spinning
wheel(s) and/or reduces power
to limit wheel spin.
The system may be heard or felt
while it is working, but this is
normal.
To assist with directional control
of the vehicle, TCS comes on
automatically whenever the vehicle
is started and cannot be turned off.

Black plate (38,1)Chevrolet Volt Owner Manual - 2011
9-38 Driving and Operating
When the vehicle is started
and begins to move, the system
performs several diagnostic checks
to ensure there are no problems.
The system may be heard or
felt while it is working. This is
normal and does not mean there
is a problem with the vehicle.
The system should initialize
before the vehicle reaches 32 km/h
(20 mph). In some cases, it may
take approximately 3.2 km (2 mi) of
driving before the system initializes.
The Traction Control System may
activate on dry or rough roads or
under conditions such as heavy
acceleration while turning or abrupt
changes in output from the electric
drive unit. When this happens,
a reduction in acceleration may
be noticed, or a noise or vibration
may be heard. This is normal.
The TCS/StabiliTrak warning light
will flash to indicate that the traction
control system is active.
If there is a problem detected, the
SERVICE TRACTION CONTROL
message displays in the DIC.
SeeRide Control System Messages
on page 5‑50. When this message
is displayed and
dcomes on and
stays on, the vehicle is safe to drive
but the system is not operational. If
dcomes on and stays on, reset
the system:
1. Stop the vehicle.
2. Turn the vehicle off and wait 15 seconds.
3. Start the vehicle.
If
dstill comes on and stays on,
the vehicle needs service.
Adding non‐GM accessories
can affect vehicle performance.
See Accessories and Modifications
on page 10‑4 for more information.

Ifdcomes on and stays on, reset
the system:
1. Stop the vehicle.
2. Turn the vehicle off and wait 15 seconds.
3. Start the vehicle.
If
dstill comes on and stays on,
the vehicle needs service.
If cruise control is being used when
StabiliTrak activates, the cruise
control will automatically disengage.
Press the cruise control button to
reengage when road conditions
allow. See Cruise Control on
page 9‑40 for more information.
Cruise Control
The cruise control lets the vehicle
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
With the Traction Control
System (TCS) or Electronic
Stability Control (ESC), the system
may begin to limit wheel spin
while you are using cruise control.
If this happens, the cruise control
will automatically disengage.
SeeTraction Control System (TCS)
on page 9‑37 orElectronic Stability
Control (ESC) on page 9‑39.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.

Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Front and Rear Parking Assist
(UFRPA) system, it assists the
driver with parking and avoiding
objects. UFRPA operates at
speeds less than 8 km/h (5 mph).
The sensors on the front and rear
bumper detect objects up to 1.2 m
(4 ft) in front of the vehicle, 2.5 m
(8 ft) behind the vehicle, and at
least 25.4 cm (10 in) off the ground.
{WARNING
The Ultrasonic Front and Rear
Parking Assist (UFRPA) system
does not replace driver vision.
It cannot detect:
.Objects that are below the
bumper, underneath the
vehicle, or if they are too
close or far from the vehicle.
.Children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before moving forward and while
backing; vehicle damage, injury,
or death could occur. Even with
UFRPA, always check in front of
the vehicle before moving forward
and behind the vehicle before
backing up. While moving forward
and backing, be sure to look for
objects and check the vehicle
mirrors.

Rear Vision
Camera (RVC)
The vehicle may have a Rear Vision
Camera (RVC) system. Read this
entire section before using it.
The RVC system can assist
the driver when backing up by
displaying a view of the area
behind the vehicle.
{WARNING
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
.Detect objects that are
outside the camera's field
of view, below the bumper,
or underneath the vehicle.
.Detect children, pedestrians,
bicyclists, or pets.(Continued)
WARNING (Continued)
Do not back the vehicle by only
looking at the RVC screen, or use
the screen during longer, higher
speed backing maneuvers or
where there could be cross-traffic.
Your judged distances using the
screen will differ from actual
distances.
If you do not use proper care
before backing up, you could
hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in
vehicle damage, injury, or death.
Even though the vehicle has
the RVC system, always check
carefully before backing up by
checking behind and around the
vehicle.
How the System Works
When the vehicle is shifted
into R (Reverse), the image
of the area behind the vehicle
appears in the center stack
display with the message CHECK
SURROUNDINGS FOR SAFETY.
The previous screen displays
when the vehicle is shifted out of
R (Reverse) after approximately
10 seconds.
To cancel the delay, do one of the
following:
.Press a button on the
infotainment system.
.Shift into P (Park).
.Reach a vehicle speed of
8 km/h (5 mph).

Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive
called methylcyclopentadienyl
manganese tricarbonyl (MMT);
ask the attendant where you buy
gasoline whether the fuel contains
MMT. We recommend against
the use of such gasolines. Fuels
containing MMT can reduce spark
plug life and affect emission
control system performance.
The malfunction indicator lamp
might turn on. If this occurs,
return to your dealer for service.Filling the Tank
