Preconditioning the vehicle before driving can
help reduce wear and reduce energy consump-
tion during a trip.
Preconditioning can be started immediately or
started at a preset time using a timer.
The function utilizes several of the vehicle's sys-
tems:
• In cold weather, the high-voltage coolant
heater (HVCH) heats the passenger com-
partment to a comfortable temperature.
• In warm weather, air conditioning cools the
passenger compartment to a comfortable
temperature.
• The electrically heated steering wheel* and
seats* can be activated.
• Heating for the windshield, rear window and
door mirrors are automatically activated as
needed.
During preconditioning in a hot climate, conden-
sation from the air conditions may drip under the
vehicle. This is normal.

is connected to an electrical outlet. A charg-
ing post that is not always active, for example
because of a timer, can cause loss of function
for preconditioning.
If the car is not connected to an electrical
socket it is still possible in a warm climate to
achieve brief cooling of the passenger com-
partment by direct starting preconditioning.
NOTE
The vehicle doors and windows should be
closed during preconditioning of the passen-
ger compartment.

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.
To achieve the best traction, power is automati-
cally directed to the wheels that have the best
grip. The system continuously calculates the
need for torque to the rear wheels, and can
immediately redistribute up to half of the engine's
torque to the rear wheels.
All-wheel drive also has a stabilizing effect at
higher speeds. In normal driving conditions, most
of the engine's power is directed to the front
wheels. When the vehicle is stationary, all-wheel
drive is always activated in preparation for maxi-
mum traction during acceleration.
All-wheel drive reacts differently depending on
which drive mode is selected.

Volvo Twin Engine combines a combustion
engine for the front wheels and an electric motor
for the rear wheels.
Two drive systemsDepending 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. 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.

Drive economically and environmentally con-
scious by thinking ahead, avoiding rapid starts
and stops and adapting driving style and speed
to the current traffic conditions.
Planning for electric drivingIt is important to plan electric motor use carefully
to achieve the best possible mileage:
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.
NOTE 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.

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 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.

When using the electric motor, Volvo Twin
Engine provides a combination of good fuel
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.

584 Using the electrical outlets
The 12 V outlet can be used for devices
intended for this such as MP3 players, coolers
and cellular phones.
The high-voltage outlet* can be used for devices
intended for this, such as chargers, laptops, etc. The ignition must be in at least mode I for the
outlets to supply current. The outlets will then be
active as long as there is sufficient charge in the
start battery.
If the engine is turned off and the vehicle is
locked, the outlets will be deactivated. If the
engine is turned off and the vehicle remains
unlocked, the sockets will remain active for up to
7 minutes.
NOTE Bear in mind that using the electrical outlets
when the engine is off could cause the starter
battery to have too low of a charge level,
which could limit other functionality.
Accessories connected to the electrical out-
lets can be activated even when the vehicle
electrical system is off or if preconditioning is
used. For this reason, disconnect plugs when
they are not in use to prevent the starter bat-
tery from becoming discharged.
WARNING •
Do not use accessories with large or
heavy plugs – they could damage the out-
let or come loose while you are driving.
• Do not use accessories that could cause
disruptions to e.g. the vehicle's radio
receiver or electrical system.
• Position the accessory so that there is no
risk of it injuring the driver or passengers
in the event of heavy braking or a colli-
sion.
• Pay attention to connected accessories
as they can generate heat that could burn
passengers or the interior.
