Adverse driving conditions for

engine oil

Adverse driving conditions can lead to abnor-
mally high oil temperature or oil consump-
tion. Below are some examples of adverse
driving conditions.

Check the oil level more frequently for long
journeys:

•

towing a caravan or trailer

•

in mountainous regions

•

at high speeds

•

in temperatures colder than -30 °C
(-22 °F) or hotter than +40 °C (+104 °F).

The above also apply to shorter driving dis-
tances at low temperatures.

Choose a fully synthetic engine oil for adverse
driving conditions. It provides extra protection
for the engine.

Volvo recommends:

IMPORTANT

In order to fulfil the requirements for the
engine's service intervals all engines are
filled with a specially adapted synthetic
engine oil at the factory. The choice of oil
has been made very carefully with regard
to service life, starting characteristics, fuel
consumption and environmental impact.

An approved engine oil must be used in
order that the recommended service inter-
vals can be applied. Only use a prescribed
grade of oil for both filling and oil change,
otherwise there is a risk of the service life,
starting characteristics, fuel consumption
and environmental impact of the car being
affected.

If engine oil of the prescribed grade and
viscosity is not used, engine related com-
ponents may become damaged. Volvo Car
Corporation disclaims any liability for any
such damage.

Volvo recommends that oil changes are
carried out at an authorised Volvo work-
shop.

Coolant — specifications

Prescribed grade:

Ready-mixed coolant

approved by Volvo. If concentrated coolant is
used, mix with 50% water (of approved
water quality, not salt water, etc.). Consult a
Volvo dealer if unsure.

Only coolant approved by Volvo should be
used in order to prevent impairment of the
cooling system, engine problems, etc.

WARNING

Swallowing coolant is hazardous, it may

cause damage to organs (kidneys). The

product contains ethylene glycol, inhibitor,

water, etc.

Transmission fluid — specifications

Under normal driving conditions, the trans-
mission fluid does not need to be changed
during the service life of the gearbox. How-
ever, it may be necessary in adverse driving
conditions.

Brake fluid — specifications

The medium in a hydraulic brake system is
called brake fluid, and it is used to transfer
pressure from e.g. a brake pedal via a master
brake cylinder to one or more slave cylinders,
which in turn act on a mechanical brake.

Prescribed grade:

Volvo Original or equiva-

lent fluid compliant with a combination of
Dot 4, 5.1 and ISO 4925 class 6.

NOTE

It is recommended that brake fluid is
changed or filled by an authorised Volvo
workshop.

Air conditioning — specifications

The car's climate control system uses a freon-
free refrigerant either R1234yf or R134a
depending on market. Information about
which refrigerant the car's climate control
system uses is printed on a decal located on
the inside of the bonnet.

Prescribed grades and volumes of fluids and
lubricants in the air conditioning system can
be read in the tables below.

Fuel consumption and CO

2

emissions

The information in the tables below is in
accordance with WLTP (Worldwide Harmon-
ised Light-Duty Vehicles Test Procedure),
which is an international test method for
vehicles equivalent to a passenger car
designed for laboratory testing.

The fuel consumption for a vehicle is meas-
ured in litres per 100 km and carbon dioxide
emissions (CO

2

) are measured in gram CO

2

per km.

Explanation

Weighted combined value. The
value is weighted between elec-
tric mode and fuel mode over the
entire drive cycle.

gram CO

2

/km

litres/100 km

Certified value for the car's
potential range ("up to") in km in
electric mode. The value should
not be interpreted as an expected
range, and the range is difficult to
achieve during normal driving.

Urban and suburban driving

Average value over all four drive
cycle phases (urban, suburban,
extra-urban and motorway driv-
ing)

Automatic gearbox

Low value

High value

NOTE

If there is no consumption and emissions
data in the table, this is available in an
enclosed supplement.

NOTE

The capacity of the hybrid battery dimin-
ishes with age and use, which may result
in increased use of the internal combustion
engine and, as a consequence, reduced
fuel economy and reduced range during
electric operation.

Drive mode PURE

The values in the table above for fuel con-
sumption, CO

2

emissions, and range for elec-

tric mode are based on special drive cycles
(see below). The car's weight may increase
depending on its equipment level. Together
with how heavily the car is loaded, this affects
fuel consumption and CO

2

emissions, and

reduces its range in electric mode. According
to WLTP, each car has unique fuel consump-
tion, CO

2

emission values and electric range

values, depending on how the car is equipped.
These values range between the low value and
high value in the table above. In many mar-
kets, you can find your car's unique fuel con-
sumption, CO

2

emission values and electric

range values in the car's registration docu-
ment.

The certified values for the car should not be
interpreted as the expected values. The certifi-
cation values are the comparative values

obtained during special drive cycles (see
below).

There are several reasons for fuel consumption
that is higher and an electric range that is
shorter than the values in the table. Examples
of these include:

•

If the car is not regularly charged from the
mains.

•

If the car is equipped with extra equip-
ment that affects its weight.

•

Driving style.

•

If the customer chooses wheels other than
those mounted as standard on the basic
version of the model, this could increase
rolling resistance.

•

High speed causes increased air resis-
tance.

•

Fuel quality, road and traffic conditions,
weather and the condition of the car.

A combination of the examples above could
increase consumption considerably.

There may be huge deviations in fuel con-
sumption if comparing to the drive cycle pro-
files (see below), which are used in the certifi-
cation of the car and on which consumption
figures in the table are based. For further infor-
mation, please refer to the referenced regula-
tions.

NOTE

Extreme weather conditions, driving with a
trailer or driving at high altitudes, in combi-
nation with poorer fuel quality than recom-
mended, are factors that considerably
increase the car's fuel consumption.

WLTP standard

From and including 1 September 2018, a new
standard was introduced for calculating con-

||

SPECIFICATIONS

680

sumption values in the car. The WLTP stand-
ard (Worldwide Harmonised Light-Duty Vehi-
cles Test Procedure) represents the average
driving conditions for everyday driving. In
comparison with the previous standard
(NEDC), WLTP takes into account more varied
traffic situations and speeds, but also equip-
ment and weight classes. Optional equipment
that affects consumption is deactivated during
testing, e.g. air conditioning, seat heating, etc.
The new standard should provide more realis-
tic figures when it comes to fuel consumption,
carbon dioxide and emissions, as well as
range for electric mode. The values are
intended to allow comparison between differ-
ent cars and not to represent your typical nor-
mal consumption and range for electric mode.

Drive cycle profiles

A drive cycle simulates actual average driving
of the car. The standard is based on four differ-
ent drive cycle profiles. The four drive cycle
profiles are:

•

Urban driving

– slow driving

•

Suburban driving

– average driving

•

Extra-urban driving

– fast driving

•

Motorway driving

– very fast driving.

Every drive cycle is determined by different
conditions such as speed, time and mileage,
for example.

The official value for combined driving, which
is shown in the table, is a combination of the
results from the four drive cycles, in accord-
ance with legal requirements.

The exhaust gases are collected in order to
extrapolate the carbon dioxide emissions (CO

2

emissions) during the four drive cycles. These
were then analysed to determine the value for
CO

2

emissions.
