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. Ground clearance is lowered 3
to reduce
air resistance and certain climate system func-
tions are reduced to provide the longest possible
driving 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.
ECO Climate
In Pure mode, ECO climate is automatically acti-
vated in the passenger compartment to help
reduce energy consumption.
NOTE 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.
OFF ROAD

Maximizes the vehicle's ability to traverse dif-
ficult terrain or poor roads.
In this mode, ground clearance 3
is high, steering
is light, and all-wheel drive and Hill Descent
Control are activated.
This drive mode is only available at low speeds,
up to 40 km/h (25 mph). If this speed is excee-
ded, Off road mode will be cancelled and AWD
mode will be activated instead. All-wheel drive requires both the combustion and
electric motor to be in continuous operation,
which results in higher fuel consumption.
In Off road mode, a compass will be displayed
between the speedometer and the tachometer in
the instrument panel. The permissible speed
range will be shown in the speedometer.

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 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.

Using the electric motor only
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.

"Hold" and "Charge" functions (p. 471) 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 rangeThe 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.

STARTING AND DRIVING
472Preparing for a long trip
It is important to have the vehicle's systems and
equipment checked carefully before driving long
distances.
Check that:
the engine is running properly and that fuel
consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlight
height if the vehicle is carrying a heavy load
tire tread depth and air pressure are at cor-
rect levels. Change to snow tires when driv-
ing in areas where there is a risk of snowy or
icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

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.

Emission controls
Three-way catalytic converter

Keep your engine properly tuned. Certain
engine malfunctions, particularly involving the
electrical, fuel or distributor ignition systems,
may cause unusually high three-way catalytic
converter temperatures. Do not continue to
operate your vehicle if you detect engine
misfire, noticeable loss of power or other
unusual operating conditions, such as engine
overheating or backfiring. A properly tuned
engine will help avoid malfunctions that
could damage the three-way catalytic con-
verter.
Do not park your vehicle over combustible
materials, such as grass or leaves, which can
come into contact with the hot exhaust sys-
tem and cause such materials to ignite under
certain wind and weather conditions.
Excessive starter cranking (in excess of one
minute), or an intermittently firing or flooded
engine can cause three-way catalytic con-
verter or exhaust system overheating.
Remember that tampering or unauthorized
modifications to the engine, the Engine Con-
trol Module, or the vehicle may be illegal and
can cause three-way catalytic converter or
exhaust system overheating. This includes:
altering fuel injection settings or compo-
nents, altering emission system components or location or removing components, and/or
repeated use of leaded fuel.NOTE Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen
content of the exhaust gases. Readings are fed
into a control module that continuously monitors
engine functions and controls fuel injection. The
ratio of fuel to air into the engine is continuously
adjusted for efficient combustion to help reduce
harmful emissions.

Fuel (p. 476) Overheating of engine and
transmission
In demanding driving conditions, such as driving
in mountainous areas or hot weather, there is a
risk of the engine or transmission overheating,
especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in front
of the grille when driving in hot weather.
If the temperature in the engine's cooling
system becomes too high, a warning symbol
will appear in the instrument panel along with
the message Engine temperature High

for a few minutes to let the transmission
cool.
If the vehicle begins to overheat, the air con-
ditioning may be temporarily switched off.
After a prolonged period of driving in
demanding conditions, do not turn off the
engine immediately after stopping.
NOTE It is normal for the engine's cooling fan to
operate for a short time after the engine is
switched off.

Preparing for a long trip (p. 472) Battery drain
The electrical functions in the vehicle drain the
battery to varying degrees. Avoid using ignition
mode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain
power from the electrical system. Do not use
functions that use a lot of electrical current when
the engine is turned off. Examples of such func-
tions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is
shown in the driver display. The vehicle's energy-
saving function will then turn off or reduce certain
functions, such as the blower and/or the audio
system.
– Charge the battery by starting the engine
and let it run for at least 15 minutes (driving
charges the battery faster than letting the
engine idle).

Follow applicable regulations regarding per-
mitted speed and weight.
Drive slowly when towing a trailer up a long
and steep incline.
The maximum trailer weights given only apply
to altitudes up to 1000 meters (3280 feet)
above sea level. At higher altitudes, engine
power (and thus the vehicle's climbing ability)
is decreased due to the reduced air density,
and the maximum trailer weight must there-
fore be reduced. The weight of the vehicle
and trailer must be decreased by 10% for
each additional 1000 m (3280 feet) or part
thereof.
Avoid driving with a trailer on inclines of more
than 12%.
Avoid overloading and other incorrect use.
The trailer's brakes must be balanced with
the vehicle's brakes to help ensure safe
stops (follow applicable local regulations).
NOTE To facilitate towing a trailer in a vehicle equip-
ped with pneumatic suspension*, select: the
Suspension Control
Dynamic
setting in
Individual drive mode.
CAUTION
Bumper-attached trailer hitches must not
be used on Volvos, nor should safety
chains be attached to the bumper.
Trailer hitches attaching to the vehicle
rear axle must not be used.
Never connect a trailer's hydraulic brake
system directly to the vehicle brake sys-
tem, nor a trailer's lighting system directly
to the vehicle lighting system. Consult
your nearest authorized Volvo retailer for
correct installation.
When towing a trailer, the trailer's safety
chains or wire must be correctly fastened
to the attachment points provided in the
trailer hitch on the vehicle. The safety
chain or wire must never be fastened to
or wound around the towing ball.
NOTE The optional detachable trailer hitch may not
be available in all markets or on all models.
Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer,
driving at high altitudes and fuel quality are
factors that significantly increase a vehicle's
fuel consumption.
Trailer weights
WARNING Please adhere to the recommendations provi-
ded for trailer weight. If the recommendations
are not followed, the vehicle and trailer may
be difficult to control during evasive maneu-
vers and braking.
NOTE
The specified maximum trailer weights are
those permitted by Volvo. National vehicle
regulations may set additional restrictions on
trailer weight and speed. The trailer hitches
may be certified for higher towing weights
than the vehicle is permitted to tow.
Self-leveling suspension*The vehicle's self-leveling system attempts to
keep the vehicle at a constant level, regardless of
load (up to the maximum permitted weight).
When the vehicle is stationary, the rear end of the
vehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of overheat-
ing when driving with a trailer. If overheating of
the engine and drive system is detected, a warn-
ing symbol will illuminate in the instrument panel
along with a message.

imprinted on the sidewall of the tire. The last four
digits in the series is the Department of
Transportation (DOT) stamp and indicates the
week and year the tire was manufactured. The
tire in the illustration has 0717 as the last four
digits, which means it was manufactured week 7
of 2017.
Tire ageTires degrade over time, even when they are not
being used. It is recommended that tires gener-
ally be replaced after 6 years of normal service.
Heat caused by hot climates, frequent high load-
ing conditions or Ultra Violet (U.V.) exposure can
accelerate the aging process. The temporary
spare
2
should also be replaced at 6-year inter-
vals, even if it has never been used. A tire with
e.g., visible cracks or discoloration should be
replaced immediately.
Tire economy
Maintain correct tire pressure.
Avoid fast starts, hard braking and tire
screeching.
Tire wear increases with speed.
Correct front wheel alignment is very impor-
tant.
Unbalanced wheels impair tire economy and
driving comfort.
Tires must maintain the same direction of
rotation throughout their lifetime.
When replacing tires, the tires with the most
tread should be mounted on the rear wheels
to reduce the chance of oversteer during
hard braking.
Hitting curbs or potholes can damage the
tires and/or wheels permanently.
Tire rotationYour vehicle has no required tire rotation. Driving
style, tire pressure, climate and road conditions
affect how quickly the tires age and exhibit signs
of wear. Maintaining the correct tire pressure
helps keep tread wear evenly distributed.
To help prevent differences in tread depth and
wear patterns forming on the tires, the front and
rear wheels should be rotated, i.e. the front tires
moved to the rear and the rear tires moved to the
front. Ideally, tire rotation should be done the first
time after approximately 5000 km (ca
3100 miles) and thereafter at 10,000 km
(approx. 6200 miles) intervals.
If you have any questions regarding tread depth,
Volvo recommends consulting an authorized
Volvo workshop. If significant differences in wear
(> 1 mm difference in tread depth) between the
tires have already occurred, the least worn tires
should always be mounted on the rear wheels. A
front-wheel skid (understeer) is usually easier to control than a rear-wheel skid (oversteer). If the
front wheels skid, the vehicle will continue in a
straight line instead of the rear wheels skidding
to the side, which could cause you to completely
lose control of the vehicle. It is therefore impor-
tant that the rear wheels never lose grip before
the front wheels.
Storing wheels and tiresWhen storing complete wheels (tires mounted on
rims), they should be suspended off the floor or
placed on their sides on the floor.
Tires not mounted on rims should be stored on
their sides or standing upright, but should not be
suspended.
CAUTION
Tires should preferably be stored in a cool,
dry, dark place, and should never be stored in
close proximity to solvents, gasoline, oils, etc.

8. U.S. DOT Tire Identification Number
(TIN): This begins with the letters "DOT" and
indicates that the tire meets all federal
standards. The next two numbers are the
factory code where the tire was manufac-
tured, the next two are the tire size code and
the last four numbers represent the week
and year the tire was made. For example,
0717 means that the tire was manufactured
during week 7 of 2017. The numbers in

manufacturer's discretion. This information
helps a tire manufacturer identify a tire for
safety recall purposes.
9. Tire Ply Composition and Material Used:
Indicates the number of plies indicates or the

Speed SymbolA tire's Speed Symbol (SS) indicates the maxi-
mum speed for which the tire has been certified
and should be at least equivalent to the vehicle's
top speed.
Winter tires, with or without studs, are exceptions
and may use a lower SS. When winter tires are
installed, the vehicle may not be driven faster
than the tires' SS.
The vehicle's speed should always be determined
by the posted speed limit and traffic and road
conditions, not the tire's SS.
The following table indicates the maximum per-
missible speed for each SS. M 130 km/h (81 mph)
