HYBRID INFORMATION
416General information about Twin
Engine
Twin Engine vehicles are driven just like any
other vehicle, but certain functions differ from a
vehicle powered exclusively by gasoline. The
electric motor powers the vehicle primarily at low
speeds; the gasoline engine is used at higher
speeds or during more active driving.
The instrument panel displays Twin Engine-spe-
cific information - charging information, selected
drive mode, distance to discharged battery and
hybrid battery charge level.
Different drive modes can be selected while driv-
ing, e.g. electric power only or, if more power is
needed, a combination of electric and gasoline
power. The vehicle calculates the optimal combi-
nation of driveability, driving experience, environ-
mental impact and fuel economy for the selected
drive mode.
In order to function optimally, the hybrid battery
(and its electrical drive systems) and the gasoline
engine (and its drive systems) must be at the
correct operating temperature. Battery capacity
can be considerably reduced if the battery is too
cold or too hot. Preconditioning prepares the
vehicle's drive systems and passenger compart-
ment before driving to help reduce both wear and
energy consumption. It also helps increase the
hybrid battery's range.
The hybrid battery which powers the electric
motor is recharged using the charging cable. It can also be recharged during light braking and
through engine braking in gear position B. The
combustion engine can also help recharge the
hybrid battery.
Important
No electrical current
Keep in mind that if there is no electrical current
to the vehicle, i.e. the ignition is switched off or
the start battery is discharged, certain functions
such as brakes, power steering, etc. will not work.
WARNING If the vehicle does not have electrical current
and both the electric motor and the gasoline
engine are switched off, the brakes cannot be
used to stop the vehicle.
Towing not permitted
Never tow a Twin Engine vehicle behind another
vehicle, as this could damage the electric motor.
Exterior engine noise
WARNING
Please be aware that there is no sound from
the engine when the vehicle is being powered
by the electric motor and it may be difficult to
detect by children, pedestrians, cyclists and
animals. This is especially true at low speeds.
High-voltage electrical current
WARNING A number of electrical components in Twin
Engine Plug-in Hybrid vehicles use high-volt-
age current and can be extremely dangerous
if handled incorrectly. These components and
any orange wiring in the vehicle may only be
handled by trained and qualified Volvo service
technicians.
Do not touch anything that is not clearly descri-
bed in this Owner's Manual.

WARNING California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To mini-
mize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, serv-
ice your vehicle in a well ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more infor-
mation go to www.P65Warnings.ca.gov/
passenger-vehicle.
The hybrid battery can be recharged using the
charging cable stored in a storage space in the
cargo compartment.
WARNING The hybrid electrical system in your vehicle
uses high voltage electrical current. Any dam-
age to this system or to the hybrid battery
may result in the danger of overheating, fire,
or serious injury. If the vehicle is involved in a
collision or subjected to flooding, fire, etc.,
have it inspected by a trained and qualified
Volvo service technician. Prior to this inspec-
tion, the vehicle should be parked outdoors at
a safe distance from any building or poten-
tially flammable materials.
The hybrid battery's charging time depends on
the charging current used.
NOTE The capacity of the hybrid battery diminishes
somewhat with age and use, which could
result in increased use of the gasoline engine
and consequently, slightly higher fuel con-
sumption.
WARNING
If the hybrid battery needs to be replaced, this
may only be done by a Volvo retailer or
authorized Volvo workshop.

Charging cable handle and charging socket.
Charging status is indicated in three ways:
The indicator lights in the charging module
(the unit connected to the wall outlet).
Indicator light in the vehicle's charging
socket.
Images and text in the instrument panel.
The start battery is charged while the hybrid bat-
tery is charging and stops charging when the
hybrid battery is fully charged.
If the hybrid battery's temperature is below
-10 ºC (14 ºF) or above 40 ºC (104 ºF), some of
the vehicle's functions may be reduced or not
available at all.
The electric motor cannot be used if the battery's
temperature is too low or too high. If the PURE
drive mode is selected, the gasoline engine will
start.
Charging using the gasoline engine The vehicle generates electrical current to charge the
battery, e.g. when the driver lightly presses the brake
pedal or when engine braking is used on downgrades.
The vehicle can also generate current to the
hybrid battery to charge it.
The hybrid battery can also be recharged by
lightly depressing the brake pedal, i.e. during
light braking. This converts the vehicle's
kinetic energy to electrical energy, which is
used to charge the hybrid battery.
In gear position B, the electric motor brakes
the vehicle when the accelerator pedal is
released and the hybrid battery is recharged
at the same time.
The combustion engine can also help
recharge the hybrid battery.Related information

Charging current
Charging current is used to charge the hybrid
battery and precondition the vehicle. Charging is
performed by connecting a charging cable
between the vehicle's charging socket and a
120/240 V electrical socket (alternating cur-
rent).
When the charging cable is activated, a message
will be displayed in the instrument panel and an
indicator light in the vehicle's charging socket will
illuminate. Charging current is primarily used for
battery charging, but is also used for precondi-
tioning. The vehicle's start battery is charged
along with the hybrid battery.
CAUTION
Never detach the charging cable from the
120/240 V outlet (AC, alternating current)
while charging is in progress – the
120/240 V outlet could be damaged in such
circumstances. Always interrupt charging first
and then disconnect the charging cable – first
from the vehicle's charging socket and then
from the 120/240 V outlet.
NOTE
In extremely cold or hot weather, part of
the charging current is used to heat/cool
the hybrid battery and the passenger
compartment, resulting in a longer charg-
ing time.
The charging time is longer if precondi-
tioning has been selected. The time
required depends primarily on the ambi-
ent temperature.
FuseThere are normally several 120/240 V power
consumers in one fuse circuit, which means that
more than one power consumer (e.g. lighting,
vacuum cleaner, electric drill, etc.) may use the
same fuse.

WARNING

The charging cable must be grounded
when in use. It is equipped with a cord
with a grounding conductor and a
grounding plug. The plug must be
inserted into an appropriate outlet that is
properly installed and grounded in
accordance with all local codes and ordi-
nances and is not damaged in any way.
Children should be supervised when in
the vicinity of the charging cable when it
is plugged in.
High voltage is present in your electric
meter housing and power distribution
service panel. Contact with high voltage
can cause death or serious personal
injury.
Do not use the charging cable if it is
damaged in any way. A damaged or mal-
functioning charging cable may only be
repaired by a workshop – an authorized
Volvo workshop is recommended.
Always position the charging cable so
that it will not be driven over, stepped on,
tripped over or otherwise damaged, or
cause personal injury.
Disconnect the charger from the wall out-
let before cleaning it.
Never connect the charging cable to an
extension cord or a multiple plug socket.
Also, refer to the manufacturer's instructions
for using the charging cable and its compo-
nents.
CAUTION Power strips, extension cords, surge protec-
tors or similar devices must not be used
together with the charging cable since this
may involve a risk of fire, electric shocks, etc.
An adapter may not be used between the
120/240 V outlet (AC, alternating current)
and the charging cable.
CAUTION
Never detach the charging cable from the
120/240 V outlet (AC, alternating current)
while charging is in progress – the
120/240 V outlet could be damaged in such
circumstances. Always interrupt charging first
and then disconnect the charging cable – first
from the vehicle's charging socket and then
from the 120/240 V outlet.
CAUTION Wipe the charging cable with a clean cloth
lightly moistened with water or a mild deter-
gent. Do not use chemicals or solvents.
The charging cable and its components must
not be rinsed or immersed in water.

device
The charging cable has a circuit breaker that
helps protect against current overloads and ther-
mal overheating.
WARNING Charging the hybrid battery may only be done
from approved, grounded 120/240 V outlets
(AC, alternating current). If the electrical cir-
cuit or electrical socket's capacity is not
known, let a licensed electrician inspect the
electrical circuit's capacity. Using a charge
level that exceeds the electrical circuit's or
electrical outlet's capacity may start a fire or
damage the electrical circuit.
WARNING
The charging cable's residual current
breaker helps protect the vehicle's charg-
ing system but cannot ensure that an cur-
rent overload will never occur.
Never use visibly worn or damaged elec-
trical sockets. Doing so could lead to fires
or serious injury.
Never connect the charging cable to an
extension cord.
Maintenance or replacement of the hybrid
battery may only be performed by a
trained and qualified Volvo service techni-
cian.
If the charging cable's residual current device is
triggered, the blue indicator light in the charging
module will not illuminate when the charging
cable is plugged into an electrical outlet (or the
red warning light will glow steadily). Have the out-
let checked by a licensed electrician or try using
another wall outlet.
