Shiftlock
The automatic transmission's shiftlock function
helps prevent inadvertently moving the gear
selector between different positions.
Automatic shiftlock
The automatic shiftlock has a separate safety
system.
From Park - P
To move to another gear from P (Park), the brake
pedal must be depressed and the ignition in
mode II.
From Neutral - N
If the gear selector is in N and the vehicle has
been stationary for at least 3 seconds (with or
without the engine running), the gear selector will
be locked in that position.
To move the gear selector from N to another
gear, the brake pedal must be depressed and the
ignition in mode II.
Messages in the instrument panel
If the gear selector is locked in position, a mes-
sage will appear in the instrument panel, e.g.

The kickdown function
Kickdown is used when maximum acceleration is
needed, e.g. when passing.
When the accelerator pedal is depressed all the
way to the floor (past the normal full accelerator
position), the transmission will automatically
engage kickdown, i.e. immediately shift down to a
lower gear.
If the accelerator pedal is released from the kick-
down position, the transmission will automatically
shift up again.
Safety function
The transmission control module is equipped with
a downshift protection feature to help prevent the
engine from overheating.
In some conditions, the transmission will prevent
downshifting/kickdown if this would lead to such
high engine speed (rpm) that the engine could
be damaged. If the driver still attempts downshift-
ing or kickdown at a high rpm, nothing will hap-
pen and the original gear will remain selected.
With kickdown, the vehicle can downshift one or
more steps at a time depending on the engine
speed. The vehicle upshifts when the engine rea-
ches its maximum rpm to prevent engine dam-
age.

All Wheel Drive (AWD)
All-wheel drive, All Wheel Drive (AWD), also
called four-wheel drive, means that power is dis-
tributed to all four wheels, which improves trac-
tion.
The electric motor that powers the rear wheels
enables electronic all-wheel drive functionality.
All-wheel drive reacts differently depending on
which drive mode is selected.

Drive systems
Volvo Twin Engine combines a combustion
engine for the front wheels and an electric motor
for the rear wheels.
Two drive systems
Depending on the selected drive mode and
power available in the electric motor, the drive
systems can either be used separately or in tan-
dem.
The electric motor gets its energy from a hybrid
battery located under the tunnel console. The
hybrid can be charged from a wall outlet or in a
special charging station. The combustion engine
can also charge the hybrid battery using a special
high-voltage generator.
Both the combustion engine and the electric
motor can generate power directly to the wheels.
An advanced control system coordinates both the
drive systems to help optimize driving economy.
STARTING AND DRIVING

Hybrid battery - The hybrid battery's function
is to store electrical current. This energy is
provided by plugging the charging cable into
an electrical outlet, through regenerative
braking or from the high-voltage generator.
This provides current to power the electric
motor and to temporarily power the electrical
air conditioning to precondition the passen-
ger compartment.
Combustion engine - The combustion engine
starts when the charge level in the hybrid
battery is too low to provide the power output
requested by the driver.
High-voltage generator
2
- Charges the hybrid
battery. Starter for the combustion engine.
Can provide the combustion engine with
extra electrical current.
Electric motor - Powers the vehicle using
electricity. Can provide extra torque and
power during acceleration. Provides electrical
all-wheel drive functionality. Regenerates
braking energy into electrical current.

Factors affecting electric motor range
(p. 455)
Starting and stopping the
combustion engine in Twin Engine
vehicles
An advanced control system determines the dis-
tance that the vehicle can be driven on the com-
bustion engine, electric motor, or both at the
same time. When driving on only the electric
motor, the vehicle may automatically start the
combustion engine due to outside circumstan-
ces, e.g. low ambient temperatures. This is com-
pletely normal. The combustion engine will also
always start when the hybrid battery is nearly
fully discharged.
Climate settings at low temperatures
At low ambient temperatures, the combustion
engine will sometimes start automatically to help
achieve the desired passenger compartment
temperature and air quality. The amount of time
the combustion engine is running can be affec-
ted by:
•
lowering the temperature
•
reducing blower speed
•
activating Pure drive mode.
Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, the
electric motor's driving range and power may be

reduced and affect how often the combustion
engine automatically starts.
Emission control system
To help ensure that the emission control system
functions optimally, the combustion engine will
run for several minutes after it is started. The
amount of time the combustion engine needs to
be used varies depending on the temperature of
the three-way catalytic converter.

Drive modes
Drive modes affect the vehicle's driving charac-
teristics in different ways to enhance and sim-
plify the driving experience in certain types of sit-
uations.
Drive modes enable easy access to the vehicle's
many functions and settings in different driving
situations. The following systems are adapted to
help optimize driving characteristics in each drive
mode:
•
Steering
•
Engine/transmission/all-wheel drive
•
Brakes
•
Shock absorbers
•
Instrument panel
•
Climate control settings
Select the drive mode that is best suited to the
current driving conditions. Keep in mind that not
all drive modes are available in all situations.
Available drive modes
WARNING
Keep in mind that the vehicle does not emit
any engine noise when using the electric
motor and may therefore be difficult to detect
for children, pedestrians, cyclists or animals.
This is particularly true at low speeds, e.g. in
parking lots.
WARNING
Do not leave the vehicle in an unventilated
area with a drive mode activated and the com-
bustion engine switched off. The engine will
start automatically if the charge level in the
hybrid battery is low and the resulting exhaust
gases can be very harmful to people and ani-
mals.

HYBRID
•
This is the default mode in which the electric
motor and combustion engine work together.
The vehicle starts in Hybrid mode. The control
system uses both the electric motor and the gas-
oline engine - separately or in tandem - and cal-
culates optimal utilization with regard to perform-
ance, fuel consumption and comfort. Driving
capacity on the electric motor alone is deter-
mined by factors such as the hybrid battery's
charge level, the need for heat/cooling in the
passenger compartment, etc.
If there is sufficient charge in the battery, it is
possible to drive solely on electric power. When
the accelerator pedal is pressed, only the electric
motor will be activated until the battery reaches a
certain charge level. Above this level, the current
in the battery cannot supply the power requested
by the accelerator pedal and the combustion
engine will start.
When the hybrid battery's charge level is low, the
combustion engine will start more frequently to
save the remaining current in the battery. Charge
the hybrid battery from a 120-240 volt outlet
using a charging cable, or activate
Charge
in
Function view to reset the option of only using
the electric motor.
This drive mode is designed for low energy con-
sumption with an optimized mix between the
electric motor and gasoline engine, without com-
promising on climate comfort or driving experi-
ence. When faster acceleration is requested by
the driver, the electric driveline will be utilized to
help provide maximum additional power. The
vehicle also monitors the driving conditions and
automatically engages all-wheel drive if neces-
sary. All-wheel drive and extra electric power are
always available regardless of the battery's
charging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will
be displayed in the instrument panel. The gauge
will indicate the amount of electrical current
required when the driver depresses the accelera-
tor pedal. The marker between the lightning and
the drop shows how much current is available.
The instrument panel gauge when both the electric
motor and the combustion engine are being used.
The instrument panel also shows how
much current is being restored to the
battery (regenerated) during light brak-
ing.
PURE
•
Uses the electric motor only, with the lowest
possible energy consumption and carbon
dioxide emissions.
This drive mode maximizes the use of the hybrid
battery. Certain climate system functions are
reduced to provide the longest distance using
only electricity.
Pure mode is available when the hybrid battery is
sufficiently charged. Even in Pure mode, the com-
bustion engine will start if the charge level in the
battery gets too low. The combustion engine will
also start
•
if the vehicle's speed goes above 125 km/h
(78 mph)
•
if the driver requests more power than the
electric motor can provide
•
if factors such as cold weather affect the
system or components.
This drive mode is optimized for maximum driving
distance with electric propulsion and is primarily
intended for use in city driving. Pure helps pro-
vide the lowest possible consumption even when
the hybrid battery is fully discharged. ECO climate
is activated to control the climate in the passen-
ger compartment, and in slippery road conditions
slightly more wheel spin may be permitted before
all-wheel drive is automatically activated.
||
STARTING AND DRIVING
448
ECO Climate
In Pure mode, ECO climate is automatically acti-
vated in the passenger compartment to help
reduce energy consumption.
When the
Pure
drive mode is activated, set-
tings for certain climate system and electricity
consuming functions are reduced. Some of
these settings can be reset manually, but full
functionality will only be restored by leaving
Pure
mode or adapting the
Individual
drive
mode to full climate system functionality.
If condensation forms on the windows, tap the
max defroster button, which will function normally.
AWD
•
Improves the vehicle's traction and handling
by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheel
drive. An optimal distribution between front and
rear axle torque helps provide the best possible
control, stability and traction, e.g. on slippery
roads or when towing a heavy trailer or another
vehicle. The AWD drive mode is always available
regardless of the hybrid battery's charge status.
Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
In the other drive modes, the vehicle automati-
cally adapts the need for all-wheel drive accord-
ing to the road surface, and can activate the elec-
tric motor or start the combustion engine as nee-
ded.
POWER
•
Power mode is designed to provide sportier
driving characteristics and a faster accelera-
tion response.
This drive mode maximizes the combined power
from the combustion engine and the electric
motor by providing power to both the front and
rear wheels. Gear shifting will be faster and more
distinct and the transmission will prioritize gears
with a higher traction force. Steering response is
faster and suspension is stiffer.
Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
This drive mode is optimized for maximum per-
formance and throttle response. It changes the
throttle response, gear shifting program and
turbo boost system. Chassis settings and steer-
ing and brake response are also optimized. The
Power drive mode is always available regardless
of the hybrid battery's charge status.
INDIVIDUAL
•
Customizes drive mode to personal preferen-
ces.
Select one of the drive modes as a basis and
adjust the settings to achieve your preferred driv-
ing characteristics. These settings will be stored
in your driver profile.
Individual drive mode is only available if it has
been activated in the center display.

Using the electric or combustion
engine
An advanced control system determines the dis-
tance that the vehicle can be driven on the com-
bustion engine, electric motor, or both at the
same time.
Its primary function is to use the motor/engine
and the current available in the hybrid battery as
efficiently as possible based on the characteris-
tics of the various drive modes and the power
output requested by the driver by pressing the
accelerator pedal.
In certain cases, temporary limitations in the sys-
tem or mandatory functions to help maintain a
low overall emissions level may result in greater
use of the combustion engine.

Energy distribution in hybrid mode
using map data*
The Hybrid drive mode is the vehicle's default
drive mode in which the electric motor and the
combustion engine work separately or together
in hybrid mode. If a destination has been
selected in the navigation system*, the Predictive
Efficiency
4
function can use map data to effec-
tively distribute the electric power throughout the
trip.
This can lower fuel consumption in comparison
with normal hybrid mode, in which the vehicle first
runs on electricity and then switches to the com-
bustion engine when the hybrid battery is dis-
charged.
If the distance to the destination is greater than
the calculated range on the electric motor, the
function will distribute electric power optimally for
the entire trip. This makes it possible to avoid sit-
uations in which normal hybrid mode would oth-
erwise use a large portion of the electric power
to e.g. use the electric motor at high speeds on a
highway and then use the combustion engine at
lower speeds during city driving.
The greatest fuel savings are attained when the
trip begins on a highway, is between 50 and 100
km (30 and 60 miles) long, and the hybrid battery
is fully charged at the start of the trip.
Requirements for the function
Certain conditions must be met for the function
to be possible:
•
A destination must be set in the navigation
system and the distance to the destination
must be longer than the possible range
using only the electric motor.
•
Hybrid drive mode must be selected.
•
The
Hold
and
Charge
functions must be
disabled.
•
The hybrid battery must be charged.
Usage tips
If you commute and it is not possible to charge
the vehicle at work, enter your workplace as a
waypoint and your home as the destination. Dis-
charging of the hybrid battery will then be distrib-
uted over the entire commute to and from work.
Add similar commutes, i.e. the route between two
charges, as
Favorites
in the navigation system to
facilitate access.

Economical driving
Drive economically and more environmentally
conscious by thinking ahead, avoiding rapid
starts and stops and adapting driving style and
speed to the current traffic conditions.
To help achieve the greatest distance with the
lowest fuel consumption with Twin Engine,
observe the following:
Charge
•
Charge the vehicle regularly by plugging it
into an electrical outlet. Make it a habit to
always begin trips with the hybrid battery fully
charged.
•
Locate charging stations along your route.
•
If possible, choose parking spots with charg-
ing stations.
Charge the vehicle from the electricity grid as
often as possible!
Preconditioning
•
Whenever possible, precondition the vehicle
before driving by connecting the charging
cable to an electrical outlet.
•
Avoid parking the vehicle somewhere where
the interior will become too hot or too cold
while the vehicle is parked. If possible, park
the vehicle in a climate-controlled garage.
•
During a short drive after passenger com-
partment preconditioning, turn off the pas-
senger compartment fan or the air condition-
ing in a hot climate.
•
If preconditioning is not possible when it is
cold outside, use seat and steering wheel
heating first. Avoid heating the entire pas-
senger compartment to reduce the amount
of current being taken from the hybrid bat-
tery.
||
STARTING AND DRIVING

Driving
•
Choose the Pure drive mode to help mini-
mize electric power consumption.
•
Maintain a steady speed and a generous fol-
lowing distance to traffic ahead to minimize
braking. This drive mode has the lowest
power consumption.
•
Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel to see available electric
power and avoid starting the combustion
engine unnecessarily. The electric motor is
more effective than the combustion engine,
especially at low speeds.
•
When braking is necessary, brake gently
using the brake pedal. This will help recharge
the hybrid battery. A regenerative function is
integrated in the brake pedal and can be
augmented by the electric motor's braking
capacity when the gear selector is in mode
B.
•
Higher speeds increase energy consumption
- air resistance increases with speed.
•
Activate the
Hold
function in the Function
view at high speeds when traveling farther
than is possible using the hybrid battery's
capacity.
•
Whenever possible, avoid using the
Charge
function to charge the hybrid battery. Charg-
ing the battery using the combustion engine
increases fuel consumption and carbon diox-
ide emissions.
•
In a cold climate, reduce heating of the wind-
shield/rear window, mirrors, seats and the
steering wheel.
•
Maintain the correct pressure in the tires and
check pressure regularly.
•
The type of tires used could affect energy
consumption - consult a retailer for advice on
suitable tires.
•
Remove unnecessary items from the vehicle
- the heavier the load, the higher the fuel
consumption.
•
Roof loads increase air resistance and
increase fuel consumption. Remove roof
boxes, ski racks, etc. that are not in use.
•
Avoid driving with the windows open.
•
Do not keep the vehicle still on an upward
gradient by using the accelerator pedal. Use
the brakes instead.

economy, low emissions and high performance.
For energy-efficient driving:
•
Select the Pure drive mode to help maximize
driving range using only the electric motor.
•
Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel's hybrid gauge to see avail-
able electric power and avoid starting the
combustion engine unnecessarily.
•
When braking is necessary, brake gently
using the brake pedal. This will recharge the
hybrid battery.
•
Activate the
Hold
function in the Function
view at high speeds when traveling farther
than is possible using the hybrid battery's
capacity.
•
Reduce current consumption in the passen-
ger compartment by reducing e.g. fan speed,
electric heating, or air conditioning use.
Also follow the general economical driving advice
regarding speed, tires and load to maximize
range.

Factors affecting electric motor
range
A number of factors affect the electric motor's
driving range. The ability to achieve a long driv-
ing range varies according to the outside condi-
tions and to how the vehicle is driven.
The certified value for the distance that can be
driven using the electric motor should not be
considered an expected driving range. The actual
range is dependent on a number of factors.
Factors affecting driving range
The driver can influence some factors affecting
driving range, but not all.
The longest range is achieved under very favora-
ble conditions when all factors positively influ-
ence range.
Factors the driver cannot control
There are several outside conditions that affect
range to varying degrees:
•
the current traffic situation
•
driving short distances
•
topography
•
ambient temperature and headwinds
•
road conditions and road surface.
The following table shows the approximate rela-
tionship between ambient temperature and driv-
ing range with normal climate settings and with
climate settings turned off.
Up to a certain limit, warmer ambient tempera-
tures increase the electric motor's driving range.

STARTING AND DRIVING
458
Winter driving
It is important to check the vehicle before driving
in cold/snowy conditions to make sure it can be
driven safely.
Before the cold season arrives:
•
Make sure the engine coolant contains 50%
antifreeze. This mixture helps protect the
engine from frost erosion down to
approx. -35 °C (-31 °F). Do not mix different
types of antifreeze as this could pose a
health risk.
•
Keep the fuel tank well filled to prevent con-
densation from forming.
•
Check the viscosity of the engine oil. Oil with
low viscosity (thinner oil) improves cold-
weather starting and reduces fuel consump-
tion when driving with a cold engine.
Low-viscosity oil should not be used with hard
driving or in hot weather.
•
Check the condition and charge level of the
start battery. Cold weather places greater
demands on the start battery and reduces its
capacity.
•
Use washer fluid containing antifreeze to
help prevent ice from forming in the washer
fluid reservoir.
Slippery driving conditions
For optimal traction and roadholding, Volvo rec-
ommends using snow tires on all wheels when-
ever there is a risk of snow or ice on the road.
Certain countries require use of winter tires
by law. Not all countries permit the use of
studded tires.
Practice driving on slippery surfaces under con-
trolled conditions to learn how the vehicle reacts.

Driving through standing water
Driving the vehicle through a deep pool of stand-
ing water on a water-covered roadway is called
fording. This must be done with great caution.
To prevent damage to the vehicle when driving
through water (e.g. on flooded roads):
•
Do not drive in water higher than the floor of
the vehicle. If possible, check the depth of
the water at its deepest point before driving
through it. Be particularly careful when driv-
ing through flowing water.
•
Do not drive faster than walking speed.
•
Do not stop the vehicle in the water. Drive
carefully forward or back the vehicle out of
the water.
•
Remember that waves created by passing
vehicles could cause the water level to rise
above the vehicle's floor level.
•
Avoid driving through salt water to help avoid
the risk of corrosion.
