Limited field of vision

The radar unit has a limited field of vision. In
some situations another vehicle is not
detected, or the detection is made later than
expected.

The radar unit's field of vision

Sometimes the radar unit is late at detect-
ing vehicles at close distances - e.g. a

vehicle that drives in between your car and
the vehicle ahead.
Small vehicles, such as motorcycles, or
vehicles not driving in the centre of the
lane can remain undetected.
In bends, the radar unit may detect a dif-
ferent vehicle than intended or lose a
detected vehicle from view.

Low trailers

Low trailer in radar shadow

Low trailers can also be difficult for the radar
unit to detect, or are not detected at all - the
driver should therefore be particularly careful
when driving behind low trailers when the
adaptive cruise control

*

or Pilot Assist

*

is acti-

vated.

Further limitations for camera

Impaired vision

The cameras have limitations similar to the
human eye, i.e. may "see" worse in for exam-
ple intense snowfall or rain, dense fog, heavy

dust storms and snow flurries. Under such
conditions, the functions of camera-depend-
ent systems could be significantly reduced or
temporarily disengaged.

Strong oncoming light, reflections in the car-
riageway, snow or ice on the road surface,
dirty road surfaces or unclear lane markings
can also significantly reduce camera function
when it is used to scan the carriageway to
detect pedestrians, cyclists, large animals and
other vehicles.

Further limitations for Park assist
camera

*

Blind sectors

There are "blind" sectors between the cameras' fields

of vision.

In the park assist camera's 360° view

*

obsta-

cles/objects may "vanish" in the gaps
between the individual cameras.

WARNING

Pay attention to the possibility that, even if

it only looks like a relatively small part of

the image is obscured, a relatively large

sector could be hidden from view. An

obstacle could thereby go undetected until

the car is very close to it.

Light conditions

The camera image is adjusted automatically
according to prevailing light conditions.

Because of this, the image may vary slightly in
brightness and quality. Poor light conditions
can result in reduced image quality.

NOTE

A bike carrier or other accessory mounted
on the rear of the car could obscure the
camera's view.

ELECTRIC OPERATION AND CHARGING

398

General information about Twin

Engine

Twin Engine runs like a regular car, but cer-
tain functions differ from a car that only runs
on petrol or diesel. The electric motor drives
the car mostly at low speeds, the petrol
engine at higher speeds, as well as during
more active driving.

The driver display shows some information
that is unique to the Twin Engine - charging
information, selected drive mode, distance to
empty battery as well as the hybrid battery's
charge level.

It is possible to set the car in different drive
modes while driving, e.g. electric operation
only or, when power is required, both electric
motor and petrol engine. The car calculates a
combination of drivability, driving experience,
environmental impact and fuel economy
according to the drive mode selected.

In order that the car should have optimal func-
tion it is important that the hybrid battery with
associated electrical drive systems, as well as
the petrol engine and its drive systems, have
the correct operating temperature. Battery
capacity may be reduced considerably if the
battery is too cold or too hot. Preconditioning
prepares the car's drive systems and the pas-
senger compartment before departure so that
both wear and energy needs during the jour-
ney are reduced. The range for the hybrid bat-
tery increases.

The hybrid battery which drives the electric
motor is charged via a charging cable but can
also be charged by gentle braking and engine
braking in gear position

B

. The hybrid battery

can also be charged by the car's engine.

Important to know

Car without power

Bear in mind that important functions such as
the brakes and power steering are inoperable
when the car is without power.

WARNING

In a de-energised car with the electric

motor and fuel-driven engine switched off

it is not possible to brake the car.

Towing not permitted

Towing the Twin Engine is not permitted since
this damages the electric motor.

Exterior engine noise

WARNING

Remember that the car does not emit any

engine noise when it is only powered by

the electric motor and may therefore be

difficult to notice by children, pedestrians,

cyclists and animals. This is especially true

at low speeds, such as in car parks.

High-voltage current

WARNING

Several components in the car work with

high-voltage current that could be danger-

ous in the event of incorrect intervention.

These components, and all orange-col-

oured cables, must only be handled by

qualified personnel.

Do not touch anything that is not clearly
described in the owner's manual.

ELECTRIC OPERATION AND CHARGING

}}

399

Charging the hybrid battery

In addition to the fuel tank, as in a conven-
tional car, the car is equipped with a
rechargeable battery - a so-called hybrid bat-
tery of the lithium-ion type.

The hybrid battery is charged using a charging
cable which is located in a storage compart-
ment in the cargo area.

NOTE

Volvo recommends a charging cable in
accordance with IEC 62196 and IEC
61851 which supports temperature moni-
toring.

The time it takes for the hybrid battery to be
charged is dependent on the charging current
that is used.

NOTE

The capacity of the hybrid battery decrea-
ses slightly with age and use, which may
result in increased use of the petrol engine
and thereby slightly increased fuel con-
sumption.

WARNING

Replacing the hybrid battery must only be

performed by a workshop - an authorised

Volvo workshop is recommended.

Charging cable handle and charging input socket.

Charging status is indicated in three ways:

•

Indicators on the charging cable's control
unit.

•

Indicator lamp in the car's charging input
socket.

•

Illustration and text in the driver display.

The starter battery is charged when the hybrid
battery is charging and terminated when the
hybrid battery is fully charged.

If the hybrid battery's temperature is below
-10

º

C (14

º

F) or above 40

º

C (104

º

F) then it

may mean that some of the car's functions are
changed or unavailable because the capacity
of the hybrid batteries is reduced outside this
temperature range.

Electric operation is not possible if the tem-
perature of the battery is too low or too high. If
drive mode PURE is then selected, the com-
bustion engine starts.

Charging with fixed control unit in
accordance with mode 3

1

In certain markets the control unit is installed
within a charging station connected to the
mains power circuit. In which case, the charg-
ing cable has no control unit of its own. There-
fore, use the charging station's charging cable
and follow the instructions at the charging sta-
tion.

ELECTRIC OPERATION AND CHARGING

400

Charging with the petrol engine

The car generates current to the battery and the bat-

tery is charged, e.g. when the brake pedal is pressed

gently or during engine braking down a hill.

The car can also generate power for the hybrid
battery and the battery is charged.

•

The hybrid battery is recharged during
gentle braking with the brake pedal. The
car's kinetic energy is then converted to
electrical energy, which is used to charge
the hybrid battery.

•

In gear position

B

, the car uses electric

motor braking when the accelerator pedal
is released, while the hybrid battery is
recharged at the same time.

•

The hybrid battery can also be charged by
the car's engine.

Charging current

Charging current is used for charging the
hybrid battery as well as preconditioning of
the car. Charging takes place with a charging
cable connected to the car's charging input
socket and a 230 V socket

2

(alternating cur-

rent).

When the charging cable is activated, the
driver display shows a message and a lamp in
the car's charging input socket illuminates.
The charging current is mainly used for battery
charging, but is also used for preconditioning
the car. When the car's hybrid battery is
charged, the starter battery is also charged.

IMPORTANT

Never unplug the charging cable from the
230 V socket (alternating current) while
charging is in progress - there is then a risk
of damaging the 230 V socket. Always
stop charging first before unplugging the
charging cable from the car's charging
input socket and then from the 230 V
socket.

The voltage in the socket may vary depending on market.

ELECTRIC OPERATION AND CHARGING

}}

}}

401

NOTE

•

If the weather is very hot or very cold,
some of the charging current is used to
heat/cool the hybrid battery and the
passenger compartment, which results
in a longer charging time.

•

The charging time is extended if pre-
conditioning has been selected. The
time required depends mainly on the
outside temperature.

Fuse

Normally several 230 V consumers are
included in a fuse circuit, so additional con-
sumers (e.g. lighting, vacuum cleaner, electric
drill, etc.) can be on the same fuse.

Ground fault breaker in the

charging cable

The control unit for the charging cable charg-
ing cable has a built-in ground fault breaker
that protects the car and the user from elec-
tric shocks caused by system faults.

WARNING

Charging the hybrid battery must only take

place with grounded and approved 230 V

sockets (alternating current). If the capacity

for the socket or fuse circuit is unknown,

ask a licensed electrician to check the

capacity. Charging above the capacity of a

fuse circuit may lead to fire or damage the

fuse circuit.

WARNING

•

The charging cable's overvoltage pro-
tection helps to protect the car's
charging system, but cannot guarantee
that overload will never occur.

•

Never use visibly worn or damaged
electrical sockets. This could cause fire
or serious injury.

•

Never connect the charging cable to a
cable extension.

•

Maintenance or replacement of the
hybrid battery must only be performed
by a trained and qualified Volvo service
technician.

•

Temperature monitoring of the

charging cable

For the car's hybrid battery to be charged
safely every time, the control unit for the
charging cable and the plug have built-in
monitoring devices for the temperature.

Temperature monitoring takes place in the
control unit and the plug.

NOTE

Volvo recommends a charging cable in
accordance with IEC 62196 and IEC
61851 which supports temperature moni-
toring.

Monitoring in the control unit

Charging is switched off if the temperature of
the control unit is too high. This is to protect
the electronics. This may take place at a high
outside temperature, for example, and/or
when strong sunlight shines directly on the
control unit.

Monitoring at the plug

If the temperature at the power source to
which the charging cable is connected is too
high, the charging current is reduced. If the
temperature exceeds a critical level, charging
is stopped completely.

IMPORTANT

If the temperature monitoring has auto-
matically lowered the charging current
repeatedly and charging has been interrup-
ted then the cause of the overheating must
be investigated and rectified.
