Engine oil

An approved engine oil must be used in order
that the recommended service intervals can be
applied.

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 intervals 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 characte-
ristics, fuel consumption and environmental
impact of the car being affected.

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

Volvo recommends that oil changes are car-
ried out at an authorised Volvo workshop.

Volvo uses different systems for warning of low/
high oil level or low oil pressure. Certain engine
variants have an oil pressure sensor, and then the
driver display's warning symbol for low oil pres-
sure

is used. Other variants have an oil

level sensor, when the driver is informed via the
driver display's warning symbol

and display

MAINTENANCE AND SERVICE

texts. Certain variants have both systems. Contact
a Volvo dealer for more information.

Change the engine oil and oil filter in accordance
with the intervals specified in the Service and
Warranty Booklet.

Using oil of a higher than specified grade is per-
mitted. If the car is driven in adverse conditions,
Volvo recommends using an oil of a higher grade
than the one specified.

Checking and filling with engine oil

The oil level is detected with the electronic oil
level sensor.

Filler pipe

In some cases, oil may need to be topped up
between service intervals.

No action with regard to engine oil level needs to
be taken until a message is shown in the driver
display.

WARNING

If this symbol is shown together

with the message

Engine oil level

Service required

, visit a workshop

- an authorised Volvo workshop is

recommended. The oil level may be too high.

IMPORTANT

If this symbol is shown together
with a message about low oil level,
such as

Engine oil level low

Refill 1 litre

for example, then only

fill the volume specified, e.g. 1 litre (1 quart).

The oil level is checked using the electronic oil
level gauge in the centre display when the engine
is switched off.

The oil level should be checked regularly.

NOTE

The system cannot directly detect changes
when the oil is filled or drained. The car must
have been driven approx. 30 km (approx.
20 miles) and have been stationary for
5 minutes with the engine switched off and
on level ground before the oil level indication
is correct.

NOTE

If the right conditions for measuring the oil
level (time after engine shutdown, the car's
inclination, outside temperature, etc.) are not
met, then the message

No value available

will be shown in the centre display. This does
not mean that there is something wrong in
the car's systems.

Topping up coolant

The coolant cools the internal combustion
engine to the correct operating temperature. The
heat that is transferred from the engine to the
coolant can be used to heat the passenger com-
partment.

When topping up the coolant, follow the instruc-
tions on the packaging. Never top up with water
only. The risk of freezing increases with both too
little and too much coolant concentrate.

If there is coolant under the car, if there is cool-
ant smoke, or if more than 2 litres have been
filled, always call for recovery to avoid the risk of
engine damage due to a defective cooling sys-
tem when attempting to start the car.

WARNING

Coolant can be very hot. If the coolant

requires topping up when the engine is at

operating temperature, unscrew the expan-

sion tank cap slowly to gently release the

overpressure.

IMPORTANT

•

A high content of chlorine, chlorides and
other salts may cause corrosion in the
cooling system.

•

Always use coolant with anti-corrosion
agent as recommended by Volvo.

•

Ensure that the coolant mixture is 50%
water and 50% coolant.

•

Mix the coolant with approved quality
water. In the event of any doubt about
water quality, used ready-mixed coolant in
accordance with Volvo recommendations.

•

When changing coolant/replacing cool-
ing system components, flush the cooling
system clean with approved quality water
or flush with ready-mixed coolant.

•

The engine must only be run with a well-
filled cooling system. Otherwise, tempera-
tures that are too high may occur result-
ing in the risk of damage (cracks) in the
cylinder head.

Starter battery

The electrical system is single-pole and uses the
chassis and engine casing as a conductor.

The starter battery is used to start up the electri-
cal system and drive electrical equipment in the
car. The hybrid battery is used when the internal
combustion engine is started.

The starter battery should be replaced by a
workshop

The starter battery is a 12 V AGM battery
(Absorbed Glass Mat), designed for the carbon
dioxide reducing functions Start/Stop and regen-
erative charging, and to support the functionality
of the car's different systems.

The service life and function of the starter battery
is influenced by factors such as the number of
starts, discharging, driving style, driving condi-
tions, climatic conditions etc.

•

Never disconnect the starter battery when
the engine is running.

•

Check that the cables to the starter battery
are correctly connected and properly tight-
ened.

WARNING

•

The battery can generate oxyhydrogen
gas, which is highly explosive. A spark can
be formed if a jump lead is connected
incorrectly, and this can be enough for
the battery to explode.

•

Do not connect the jump leads to any
fuel system component or any moving
part. Be careful of hot engine parts.

•

The battery contains sulphuric acid, which
can cause serious burns.

•

If sulphuric acid comes into contact with
eyes, skin or clothing, flush with large
quantities of water. If acid splashes into
the eyes - seek medical attention imme-
diately.

•

Never smoke near the battery.

When connecting an external starter battery or
battery charger, use the car's charging points in
the engine compartment. The battery terminals
on the car's starter battery in the cargo area must
not be used.

IMPORTANT

It is not possible to charge another car’s bat-
tery by means of current through the charging
points. Using the charging points to charge
another car's battery may cause a fuse to
blow, which means that the charging points
will stop working.

Positive charging point

Negative charging point

An authorised Volvo workshop is recommended.

MAINTENANCE AND SERVICE

}}

565

IMPORTANT

When charging the starter battery, only use a
modern battery charger with controlled charg-
ing voltage. Fast charging function must not
be used since it may damage the battery.

NOTE

If both the starter battery and the hybrid bat-
tery are discharged then both batteries must
be charged. In such a case, charging only the
hybrid battery first is not possible.

In order for the hybrid battery to be charged
the starter battery must have a certain state
of charge.

IMPORTANT

If the following instruction is not observed
then the energy saving function for infotain-
ment may be temporarily disengaged, and/or
the message in the driver display about the
starter battery's state of charge may be tem-
porarily inapplicable, following the connection
of an external starter battery or battery
charger:

•

The negative battery terminal on the car's
starter battery must never be used for
connecting an external starter battery or
battery charger - only the car's negative
charging point may be used as the
grounding point.

NOTE

The life of the battery is shortened if it
becomes discharged repeatedly.

The life of the battery is affected by several
factors, including driving conditions and cli-
mate. Battery starting capacity decreases
gradually with time and therefore needs to be
recharged if the car is not used for a longer
time or when it is only driven short distances.
Extreme cold further limits starting capacity.

To maintain the battery in good condition, at
least 15 minutes of driving/week is recom-
mended or that the battery is connected to a
battery charger with automatic trickle charg-
ing.

A battery that is kept fully charged has a
maximum service life.
