Kick-down function

Kick-down can be used when maximum
acceleration is needed such as for overtaking.

When the accelerator pedal is pressed all the
way to the floor (beyond the position normally
regarded as full acceleration) a lower gear is
immediately engaged. This is known as kick-
down.

If the accelerator is released from the kick-
down position, the gearbox automatically
changes up.

Safety function

To prevent over-revving of the engine, the
gearbox control program has a protective
downshift inhibitor.

The gearbox does not permit downshifting/
kick-down which would result in an engine
speed high enough to damage the engine.
Nothing happens if the driver still tries to shift
down in this way at high engine speed – the
original gear remains engaged.

On kick-down the car can shift down one or
more steps at a time, depending in engine
speed. The car shifts up when the engine has
reached is maximum engine speed in order to
prevent engine damage.

Drive systems

The car combines an internal combustion
engine that drives the front wheels with an
electric motor that drives the rear wheels.

Two drive systems

Depending on the driver-selected drive mode
and available electric energy, the two drive
systems can be used either individually or in
parallel.

The electric motor is supplied its energy from
a hybrid battery fitted in the tunnel console.
The hybrid battery can be charged in a wall
socket, or in a special charging station. The
internal combustion engine can also charge
the hybrid battery with a special high-voltage
generator.

Both the internal combustion engine and elec-
tric motor can generate motive force directly
to the wheels. An advanced control system
combines the properties of both drive systems
in order to provide optimum driving economy.

Hybrid battery - The function of the hybrid
battery is to store energy. It receives
energy when charging from the mains
power circuit, during regenerative braking
or from the high-voltage generator. It pro-
vides energy for electric operation as well
as for temporarily operating the electric air
conditioning during the preconditioning of
the passenger compartment.
Internal combustion engine - The internal
combustion engine starts when the
energy level in the hybrid battery is insuffi-
cient for the engine power that the driver
requests.
High voltage generator

 - Charges the

hybrid battery. Starter motor for the inter-
nal combustion engine. Can support the

internal combustion engine with extra
electrical energy.
Electric motor - Powers the car in electric
operation. If necessary, provides extra tor-
que and power during acceleration. Pro-
vides electrical all-wheel drive functional-
ity. Recycles brake energy to electrical
energy.

Starting and stopping the

combustion engine

An advanced control system determines the
extent to which the car is driven on internal
combustion engine, electric motor or both in
parallel. During electric operation, the car
may sometimes need to start the internal
combustion engine automatically due to
external circumstances, e.g. in low outside
temperatures, which is completely normal. In
addition, the internal combustion engine
always starts when the hybrid battery rea-
ches its lowest state of charge.

Climate settings at low temperatures

In low outside temperatures, the internal com-
bustion engine sometimes starts automatically
in order to achieve the desired passenger
compartment temperature and air quality. The
amount of time that the internal combustion
engine runs can be affected by

•

lowering the temperature

•

reducing the fan strength

•

activating drive mode 

Pure

.

Electric operation in low or high
temperatures

In low or high outside temperatures, the car's
range and output for electric operation may be
reduced and affect how often the internal
combustion engine is started automatically.

Emission control

To ensure that emission control operates as
energy-efficiently as possible, the internal
combustion engine must be run for several
minutes once it has been started. The duration
of the internal combustion engine's running
time varies depending on the temperature of
the catalytic converter.

Drive modes

Selection of drive mode affects the car's driv-
ing characteristics in order to enhance the
driving experience and facilitate driving in
special situations.

Using the drive modes it is possible to quickly
have access to the car's numerous functions
and settings for different driving needs. Each
drive mode is adapted to provide optimum
driving characteristics:

•

•

Engine/gearbox/all-wheel drive

•

•

Shock absorption

•

•

Climate settings

Select the drive mode adapted for the current
driving conditions. Remember that not all
drive modes are available in all situations.

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 applies in partic-

ular at low speeds such as in car parks.

||

STARTING AND DRIVING

WARNING

Do not leave the car in an unventilated area

with activated drive mode and the fuel-

driven engine switched off - automatic

engine start occurs at low energy level in

the hybrid battery, and the exhaust gases

could then cause serious injury to people

and animals.

Hybrid

•

This is the car's normal mode where the
electric motor and internal combustion
engine work together.

When the car starts, it is in the 

Hybrid

 mode.

The control system uses both the electric
motor and internal combustion engine – indi-
vidually or in parallel – and adapts use with
regard to performance, fuel consumption and
comfort. The capacity to run solely with the
electric motor depends on the hybrid battery's
energy level and, for example, the need for
heating or cooling in the passenger compart-
ment.

If high power output is available, it is possible
to drive with electrical power alone. When the
accelerator pedal is depressed, only the elec-
tric motor is activated until a certain position is
reached. The internal combustion engine
starts when this position is exceeded and the
energy level in the battery is insufficient for the
engine power that the driver requests with the
accelerator pedal.

At low energy level (hybrid battery almost
empty) the battery's energy level must be
maintained, leading to the internal combustion
engine starting more often. Charge the hybrid
battery from a 230 VAC socket with the
charging cable, or activate 

Charge

 in the func-

tion view in order to restore the capacity to
run on electricity alone.
The drive mode is designed for low energy
consumption with a mix of the electric motor
and the internal combustion engine, without
compromising the climate comfort and driving
experience. When higher acceleration is
required, maximum additional power from the
electric drive line is used.

The car also senses if the driving conditions
require all-wheel drive and automatically
engages it if necessary. All-wheel drive and
electric additional power are always available
regardless of the battery's state of charge.

Information in the driver display

When driving in hybrid mode the driver display
shows a hybrid gauge. The pointer in the
hybrid gauge indicates how much energy the
driver requests with the accelerator pedal. The
marking between the lightning bolt and the
drop shows how much energy is available.

The driver display for propulsion with both the elec-

tric motor and internal combustion engine.

The driver display also shows when
energy is returned to the battery
(regenerated) during light braking.

469

Pure

•

Drive the car with electric motor, with
energy consumption as low as possible
and with lowest possible carbon dioxide
emissions.

The drive mode prioritises driving on the
hybrid battery. This means, for example, that
the output of certain climate settings is
reduced to provide the longest possible mile-
age on electric power alone.

The 

Pure

 mode is available when the hybrid

battery has a sufficiently high energy level. The
internal combustion engine also starts in the

Pure

 mode if the energy level in the battery

falls too low. The internal combustion engine
also starts

•

if the speed exceeds 125 km/h (78 mph)

•

if the driver requests more motive force
than electric drive can provide

•

in the event of system/component limita-
tions e.g. low outside temperature.

NOTE

The internal combustion engine may start
temporarily in certain driving situations
when the 

Pure

 drive mode is in use. This is

in order to provide the wheels with the
desired torque in driving situations that
require higher load, e.g. when driving with
a trailer or on an uphill gradient.

The drive mode is adapted for maximum range
with electric propulsion and especially devel-
oped for urban traffic. 

Pure

 means lowest

combustion even when the hybrid battery is
empty. The climate in the passenger compart-
ment is regulated to Eco climate, and in slip-
pery driving conditions, more wheel spin can
be permitted before all-wheel drive is acti-
vated automatically.

ECO climate control

In the 

Pure

 drive mode, eco climate control is

activated automatically in the passenger com-
partment in order to reduce energy consump-
tion.

NOTE

When the 

Pure

 drive mode is activated,

several parameters in the climate control
system's settings are changed, and several
electricity consumer functions are reduced.
Certain settings can be reset manually, but
full functionality is only regained by leaving

Pure

 drive mode or adapting 

Individual

drive mode with full climate functionality.

In the event of difficulties due to misting,
press the button for max. defroster which has
normal functionality.

Constant AWD

•

Improve the car's roadholding and traction
with enhanced all-wheel drive.

The drive mode locks the car in all-wheel drive.
An adapted distribution between the front and
rear axle torque provides good traction, stabil-
ity and roadholding, for example on slippery
roads, when driving with a heavy trailer, or
when towing. 

Constant AWD

 drive mode is

always available regardless of the battery's
state of charge.

Both the internal combustion engine and elec-
tric motor are engaged in order to drive all four
wheels, which results in increased fuel con-
sumption.

In the car's other drive modes, the car auto-
matically adapts the need for all-wheel drive to
the road surface, and can engage the electric
motor or start the internal combustion engine
when necessary.

Power

•

The car has sportier characteristics and
faster response to accelerating.

The drive mode adapts the combined power
from the internal combustion engine and elec-
tric motor by means of the car being driven by
both front and rear wheels. The gear changes
become faster and more distinct, and the
gearbox prioritises a gear with greater trac-
tion. Steering response is faster and shock
absorption is harder.

Both the internal combustion engine and elec-
tric motor are engaged in order to drive all four
wheels, which results in increased fuel con-
sumption.
The drive mode is adapted for maximum per-
formance and response on acceleration. It
changes the internal combustion engine's
accelerator pedal response, gear shift pattern
and boost pressure system. Chassis settings,
steering and brake response are also as good
as possible.

An advanced control system determines the
extent to which the car is driven on internal
combustion engine, electric motor or both in

The primary function is to use the engine or
motor and the available energy in the hybrid
battery as efficiently as possible, with regard
to the characteristics of the different drive
modes as well as the driver's request for
power via the accelerator pedal.

 function distributes the

electric energy consumption along the whole
driving distance using the map data.

In addition to the map data, the function also
takes into account speed limits, traffic and ele-
vation differences.

The electric motor is used primarily when driv-
ing at low speeds e.g. during city driving with
more stops and starts. The combustion engine
is used primarily when driving at high speeds
and can, in good conditions, generate power
for the electric motor.

Conditions for the function

For the function to work requires that a num-
ber of conditions are met:

•

A destination is set in the navigation sys-
tem and the driving distance to the desti-
nation is longer than the range possible
only on electric drive.

•

Hybrid

 drive mode is selected.

•

The

 functions are deac-

tivated.

Tips for use

If the car is used for commuting to work and it
is not possible to charge the car at the place of
work, specify the place of work as an inter-
mediate destination and your home as the
final destination. The discharging of the hybrid
battery will then take place over your runs
both to and from work.

Add similar commuting routes, i.e. the route
between two charging points, as 

Favourites

in the navigation system to facilitate arrival.

Level control

*

 and shock

absorption

Level control and shock absorption are regu-
lated automatically in the car.

With rear level control, the car maintains the
same height at the rear regardless of load.
Level control can also occur even after the car
has been parked.

Shock absorption (Four-C)

On a car equipped with Four-C the shock
absorption is adapted according to the drive

mode selected and the speed of the car.
Shock absorption is normally set for optimum
comfort and is regulated continuously depend-
ing on the road surface, the car's acceleration,
braking and cornering.

During transport

During transport of the car on a ferry, train or
truck, the car must be lashed around the tyres
and not around other parts of the chassis.
Changes in the air suspension may occur dur-

ing transport, which could affect the lashing
negatively.

Recommendations for loading (p. 595)

Economical driving

To achieve the longest possible range, the
driver should plan driving and adapt driving
style and speed to the prevailing situation.

Before driving

•

Precondition the car before driving if pos-
sible using the charging cable connected
to the mains power circuit.

•

If preconditioning is not possible when it
is cold outside, use seat heating and steer-
ing wheel heating first of all. Avoid warm-
ing up the whole of the interior which
takes energy from the hybrid battery.

•

Choice of tyres and tyre pressure can
affect energy consumption - seek advice
on suitable tyres from an authorised Volvo
dealer.

•

Remove unnecessary items from the car -
the greater the load the higher the con-
sumption.

While driving

•

Activate drive mode 

Pure

.

•

Activate the 

Hold

 function at higher

speeds during journeys that are longer
than the range of the electricity.

•

If possible, avoid using the 

Charge

 func-

tion to charge the hybrid battery.

•

Drive at a steady speed and keep a good
distance to other vehicles and objects in
order to avoid braking.

•

The hybrid battery is recharged during
braking by braking gently with the brake
pedal.

•

High speed results in increased energy
consumption since the wind resistance
increases with speed.

•

In a cold climate, reduce electrical heating
of windows, mirrors, seats and steering
wheel, if possible.

•

Avoid driving with open windows.

•

Do not hold the car stationary on a hill
with the accelerator pedal. Instead, acti-
vate the function for braking when station-
ary.

•

If possible, deactivate the climate control
while driving a short distance after pre-
conditioning.

After driving

•

If possible, park in an acclimated garage
with charging facilities.

Range

The car's range depends on several factors.
The ability to achieve a long range varies
according to the circumstances and condi-
tions under which the car is being driven.

The certified value for the car's mileage should
not be interpreted as an expected range. The
certified value should primarily be used to
compare different cars and is obtained during
special test cycles.

Range in the driver display

When the car is delivered from the factory, or
after a factory reset, the range is based on the
certified value

When the car has been driven for a while, the
range is based on historical driving patterns.
The amount of history used depends on the
battery's state of charge. Therefore, the less

charge there is in the hybrid battery, the faster
the range adapts to a changed driving pattern.

Factors that affect the range

In addition to historical trip data, there are sev-
eral different factors that affect the range. The
longest range is achieved under extremely
favourable conditions when all factors have a
