Black plate (29,1)Chevrolet Volt Owner Manual - 2012
In Brief 1-29
Use Mountain Mode prior to
climbing long, steep grades in
mountainous areas. Be sure to
engage Mountain Mode before
starting to climb. Mountain Mode
reduces electric range and power
but may be needed to maintain
speeds above 96 km/h (60 mph)
when climbing grades of 5% or
greater.
Use L (Low) in heavy stop‐and‐go
traffic or when traveling downhill.
L (Low) requires less brake pedal
application and provides a
controlled, efficient way to slow
the vehicle down.
Climate Setting
Using the heat and air conditioning
systems decreases the energy
available for electric driving.
Optimal energy efficiency is
achieved with the heat, air
conditioning, and fan turned off.Less energy is used at low fan
speeds. When using the fan:
.Fan Only is the most energy
efficient climate setting as long
as
0is not selected.
.ECO is for moderate air
conditioning and heater
operation and is the next most
energy efficient setting as long
as
0is not selected.
.Comfort provides the most
comfort but is the least energy
efficient.
Use the auto heated seat feature
instead of climate settings. Heating
the seat uses less energy than
heating the vehicle interior.
Use remote start to heat or cool the
interior when the vehicle is plugged
in to maximize the electric range by
utilizing electricity from the electrical
outlet. Engine Assisted Heating operation,
if equipped, can be personalized.
See
Vehicle Personalization on
page 5‑56 for more information.
In hot weather, avoid parking in
direct sunlight or use sunshades
inside the vehicle.
Turn off the front and rear window
defog/defrost when they are no
longer needed.
Avoid driving with the windows open
at highway speeds.
Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the
next drive. This is important when
outside temperatures are extremely
hot or cold.

Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑44.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest. Other driving tips include:
.Keep the vehicle well ventilated.
.Keep the interior
temperature cool.
.Keep your eyes moving
—scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. See
“Mountain Mode” underDriver
Selected Operating Modes on
page 9‑25. Tips for driving in these
conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
electric drive unit.
.Keep the vehicle in gear when
going down steep or long hills.
{WARNING
Coasting downhill in N (Neutral)
or with the vehicle turned off is
dangerous. The brakes will have
to do all the work of slowing down
the vehicle and could become too
hot. Hot brakes may not be able
to slow the vehicle enough to
maintain speed and control. You
could crash. Always have the
vehicle running and in gear
(preferably LOW range) when
going downhill. This will allow the
electric drive unit to assist in
slowing and maintaining speed.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Top of hills: Be
alert —something could be in
your lane (stalled car, accident).

STOPPING THE VEHICLE/OFF:
To turn the vehicle off, push the
POWER
Obutton with the vehicle
in P (Park). Retained Accessory
Power (RAP) will remain active until
the driver door is opened. See
Retained Accessory Power (RAP)
on page 9‑21. When turning off the
vehicle, if the vehicle is not in
P (Park), the vehicle will go to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
See Electric Drive Unit Messages
on page 5‑49. If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the vehicle
off by pushing the POWER
O
button.
4. Set the parking brake. See Electric Parking Brake on
page 9‑34.
{WARNING
Turning off the vehicle while
moving may disable the airbags.
While driving, only shut the
propulsion system off in an
emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold the POWER
O
button for longer than two seconds,
or press twice in five seconds.

9-42 Driving and Operating
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle speed. When the brakes are
applied the cruise control is
disengaged.Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal;
when cruise control disengages,
the indicator light will not be lit.
.Press*.
.Press1to turn the cruise
control system off completely.
The cruise control cannot be
resumed.
Erasing Speed Memory
The cruise control set speed is
erased from memory by pressing
1
or if the vehicle is turned off.
Object Detection
Systems
Ultrasonic Parking Assist
If available, the Ultrasonic Front and
Rear Parking Assist (UFRPA)
system 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 cm (10 in)
off the ground.

Black plate (43,1)Chevrolet Volt Owner Manual - 2012
Driving and Operating 9-43
{WARNING
The Ultrasonic Front and Rear
Parking Assist (UFRPA) system
does not replace driver vision.
It cannot detect:
.Objects that are below the
bumper, under the vehicle,
or 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 up, 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 up, be sure
to look for objects and check the
vehicle mirrors.
How the System Works
When the vehicle is shifted into
R (Reverse) the front and rear
sensors are automatically turned on.
After the vehicle is shifted out of
R (Reverse), the rear sensors are
turned off and the front sensors stay
on until the vehicle is above a
speed of 8 km/h (5 mph). For the
front park assist system to be active
again without shifting into
R (Reverse), the park assist button
in the overhead console must be
pressed. See “Turning the System
On and Off” later in this section.
UFRPA operates only at speeds
less than 8 km/h (5 mph).
When the vehicle is in N (Neutral),
the system may be active. If the
vehicle is in a car wash, the sensors
may detect objects in the car wash.
See “Turning the System On and
Off” later in this section to turn the
system off. High-toned beeps from the front
speakers are for objects detected
near the front bumper. Low-toned
beeps from the rear speakers are
for objects detected near the rear
bumper. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds.
To be detected, objects must be at
least 25 cm (10 in) off the ground
and below hatch level. Objects must
also be within 1.2 m (4 ft) in front of
the vehicle and 2.5 m (8 ft) from the
rear bumper. This distance may be
less during warmer or humid
weather.

Black plate (44,1)Chevrolet Volt Owner Manual - 2012
9-44 Driving and Operating
Objects Detected by Both the
Front and Rear Sensors
In general, if objects are detected at
the same time near both the front
and rear bumpers while backing up,
the beeps only sound to indicate
that objects are close to the rear
bumper.
However, if an object comes within
0.3 m (1 ft) of the front bumper while
the vehicle is backing up and at the
same time there is another object
further than 0.3 m (1 ft) from the rear
bumper, then the beeps only sound
to indicate the object that is closer
to the front bumper.Turning the System On and Off
The UFRPA system can be turned
on and off by pressing the park
assist button located in the
overhead console.
The LED next to the park assist
button lights up when the system is
on and turns off when it has been
disabled.
When the system is off, PARK
ASSIST OFF displays on the Driver
Information Center (DIC). The
message disappears after a short
period of time.
UFRPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST:If
this message occurs, take the
vehicle to your dealer to repair the
system.
PARK ASSIST OFF: If the UFRPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
.The driver has disabled the
system.
.The ultrasonic sensors are not
clean. Keep the vehicle's
bumpers free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑85.
