In Brief 1-5
Remote Start
Use remote start to heat or cool the
interior when the vehicle is plugged
in to maximize electric range by
utilizing electricity from the wall
outlet. The engine may start to
support the climate control
operation. Normal operation of the
system will return after the vehicle
has been turned on.
Activating the Remote Start
1. Aim the RKE transmitter at thevehicle.
2. Press
Qon the RKE transmitter;
the doors will lock.
3. Within five seconds, press and hold
Buntil the turn signal
lamps flash, or for approximately
four seconds. Pressing
Bagain
during a remote start will turn the
feature off. After entering the vehicle during a
remote start, press the POWER
O
button on the center stack with the
brake pedal applied to operate as
normal.
Canceling Remote Start
To cancel a remote start, do any of
the following:
.Aim the RKE transmitter at the
vehicle and press and hold
B
until the parking lamps turn off.
.Turn on the hazard warning
flashers.
.Press the POWERObutton on
the center stack, with the brake
pedal applied, then press the
POWER
Obutton again to turn
the vehicle off.
See Remote Start on page 2‑8.
Door Locks
Keyless Access
The RKE transmitter must be within
1 m (3 ft) of the door being opened.
To unlock the door from the driver
door, press the lock/unlock button
on the door handle. Press again
within five seconds to unlock all
passenger doors.

Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
to a significant loss in pressure of
one of the vehicle's tires. If the
warning light comes on, stop as
soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. SeeVehicle Load
Limits on page 9‑12. The warning
light will remain on until the tire
pressure is corrected. During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early
indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver
’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑51.
Tire Sealant and
Compressor Kit
This vehicle may have a tire sealant
and compressor kit that can be used
to seal small punctures in the tread
area of the tire. Significant sidewall
damage will require the tire to be
replaced.
See Tire Sealant and Compressor
Kit on page 10‑67 for complete
operating information.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.

Black plate (28,1)Chevrolet Volt Owner Manual - 2012
1-28 In Brief
Resetting the Oil Life System
1. Use the SELECT knob to selectOIL LIFE on the DIC menu.
2. Press SELECT to start the OIL LIFE reset procedure.
3. The DIC menu will display “Are
you sure that you want to reset?”
Use SELECT to choose YES to
reset oil life or NO to exit and
return to the previous menu.
4. If YES is selected, the DIC menu will display RESET OIL LIFE for
a short time and then 100% OIL
LIFE will be displayed when OIL
LIFE is successfully reset.
See Engine Oil Life System on
page 10‑12.Driving for Better Energy
Efficiency
Use the following tips to help
maximize energy efficiency and
range.
Driving Style
Efficiency Gauge (Instrument
Cluster)
The ball indicator should be kept
green and in the center of the
gauge.
Inefficient acceleration is indicated
when the ball turns yellow and
travels above the center of the
gauge.
Aggressive braking is indicated
when the ball turns yellow and
travels below the center of the
gauge. Acceleration/Braking/Coasting
Avoid unnecessary rapid
accelerations and decelerations.
Electric range is maximized at
80 km/h (50 mph) and below. Higher
speeds use more energy and can
significantly reduce electric range.
Use cruise control when
appropriate.
Plan ahead for decelerations and
coast whenever possible. For
example, do not rush to traffic
signals.
Do not shift to N (Neutral) to coast.
The vehicle recovers energy while
coasting and braking in D (Drive)
or L (Low).
Drive Mode and PRNDL Selection
Use Normal Mode when possible.
Sport Mode provides more
responsive acceleration than
Normal Mode but can reduce
efficiency.

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.

Black plate (9,1)Chevrolet Volt Owner Manual - 2012
Keys, Doors, and Windows 2-9
.If the vehicle has heated seats,
and this feature has been
enabled through vehicle
personalization, the heated
seats will turn on during colder
outside temperatures. See
“Remote Start Heated Seats”
underHeated Front Seats on
page 3‑6 and“Remote Start
Auto Heated Seats” under
Vehicle Personalization on
page 5‑56 for additional
information.
.The rear defogger will turn on
during colder outside
temperatures.
.Selecting1during colder
outside temperatures before
shutting the vehicle off will help
windshield clearing.
.Shutting the vehicle off in ECO
Mode without
1selected will
minimize the impact to electric
range. Shutting the vehicle off in
other modes will maximize
heating or air conditioning.
.The engine may start to provide
energy for heating and cooling,
independent of the vehicle being
plugged in or completely
charged. Engine Assisted
Heating operation, if available,
can be personalized. See
“Engine Assisted Heating” under
Vehicle Personalization on
page 5‑56.
.Vehicle range may decrease if
the vehicle is not plugged into
an electrical outlet. If the vehicle
is plugged in, much of the
energy needed to support this
feature will be provided from the
utility, not from the high voltage
battery. Laws in some communities may
restrict the use of features that
remotely start the engine. For
example, some laws may require a
person using the remote start
feature to have the vehicle in view
when doing so. Check local
regulations for any requirements on
remote starting of vehicles.
With the remote start feature, the
RKE transmitter functions will have
an increased range of operation.
However, the range may be less
while the vehicle is running.
Other conditions can affect the
performance of the transmitter. See
Remote Keyless Entry (RKE)
System on page 2‑2
for additional
information.
