When a critical situation has passed, the seat beltand the electric seat belt tensioner are resetautomatically. However, they can also be resetmanually.

WARNING
Never attempt to alter or repair the seat belton your own. Volvo recommends contactingan authorized Volvo workshop.
If the seat belt has been exposed to extremeforces, e.g. in conjunction with a collision, theentire seat belt must be replaced. Even if theseat belt appears undamaged, some of itsprotective properties may have been lost. Alsoreplace the seat belt if it is worn or damaged.The new seat belt must be type approved andintended for the same seating position as thereplaced seat belt.

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
• Pneumatic suspension* and 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. At high
speeds, ground clearance is automatically low-
ered 4
to reduce air resistance. Driving capacity on
the electric motor alone is determined by factors such as the hybrid battery's charge level, the
need for heat/cooling in the passenger compart-
ment, 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. 4
For vehicles with pneumatic suspension.

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.

Speed limiter (p. 278)
• Tire sealing system (p. 572) 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.
CAUTION 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 conditionsFor 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.
NOTE 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.
