4. Position the jack or the lift arms at the

designated spots of the car's undercar-
riage. The triangle markings in the plastic
cover indicate the locations of the jacking/
lifting points. There are two jacking points
on each side of the car. There is a recess
for the jack at each point.

5. Position the jack on level, firm and non-

slippery ground under the jacking point
that will be used.

6. Crank up until it is correctly aligned and so

that it makes contact with the car's jack-
ing point. Check that the head of the jack
(or lifting arms at a workshop) is correctly
positioned in the jacking point so that the
bump in the centre of the head fits into the
jacking point hole, and check that the
base of the jack is positioned vertically
below the jacking point.

7. Turn the jack so that the crank is as far

away from the side of the car as possible,
at which point the jack's arms are perpen-
dicular to the direction of the car.

8. Raise the car high enough to perform the

intended measure.

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 dis-
claims any liability for any such damage.

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

Symbols for low oil level

Volvo uses different systems to warn about
the oil level if it is too low/high, or in the event
of low oil pressure. The driver display's warn-
ing symbol for low oil pressure is used for the
oil pressure sensor

. For oil level sensor,

the driver is informed via the driver display's
warning symbol

and display texts. Cer-

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

Change the engine oil and oil filter in accord-
ance with the intervals specified in the Service
and Warranty Booklet. Using oil of a higher
than specified grade is permitted. If the car is
driven in adverse conditions, Volvo recom-
mends using an oil of a higher grade than the
one specified.

to show the oil level.

MAINTENANCE AND SERVICE

589

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 station-
ary 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 dis-

play. This does

not

mean that there is

something wrong in the car's systems.

IMPORTANT

If this symbol is shown then the
oil pressure may be too low. Stop
the car as quickly as possible and
have the car recovered to a work-

shop – an authorised Volvo workshop is
recommended.

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 pas-
senger compartment.

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

If there is coolant under the car, if there is
coolant smoke, or if more than 2 litres (approx.
2 quarts) have been filled, always call for
recovery to avoid the risk of engine damage
due to a defective cooling system when
attempting to start the car.

WARNING

The coolant may be very hot. Never open

the cap when the coolant is hot. If a top-up

is required, unscrew the expansion tank

cap slowly to allow any overpressure to

disappear.

Coolant expansion tank

–

Screw off the cap and top up with coolant
if necessary. The coolant level must not
exceed the

MAX

mark outside the expan-

sion tank.

IMPORTANT

•

Harmful if ingested. May cause organ
(kidney) damage.

•

Use ready-mixed coolant as recom-
mended by Volvo. If concentrated liq-
uid is used, make sure that the ratio is
50 % coolant to 50 % water of an
approved quality.

•

Do not mix different coolants.

•

Only new coolant should be used
when replacing major cooling system
components to ensure the system has
sufficient corrosion protection.

•

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

•

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

Starter battery

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

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

The starter battery is a 12 V AGM battery
(Absorbed Glass Mat), designed for regenera-
tive charging, and to support the functionality
of the car's different systems.

The service life and function of the starter bat-
tery is influenced by factors such as the num-
ber of starts, discharging, driving style, driving
conditions, climatic conditions etc.

•

Never disconnect the starter battery when
the engine is running.

•

Check that the cables to the starter bat-
tery are correctly connected and properly
tightened.

WARNING

•

The battery can generate oxyhydrogen
gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected 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 immediately.

•

Never smoke near the battery.

The service life and capacity of the
starter battery

The service life of the battery is affected by
several factors, including factors such as the
number of starts, discharging, driving style,
driving conditions, climatic conditions, etc.
Battery starting capacity decreases gradually
with time and therefore needs to be recharged
if the car is not used for a long time or when it
is only driven short distances. Extreme cold
further limits starting capacity. If the starter

battery is discharged a large number of times,
it will negatively affect the service life.

In order to maintain the starter battery in good
condition, it is recommended that there is at
least 15 minutes driving/week or that the bat-
tery is connected to a battery charger with
automatic trickle charging. A starter battery
that is kept fully charged has a maximum serv-
ice life.

Location

The starter battery is located in the cargo area.

WARNING

If the starter battery is disconnected, the

automatic opening and closing function

must be reset to work properly. A reset

must take place for pinch protection to

work.

Hybrid battery

The car is equipped with a hybrid battery for
electric motor operation - a maintenance-free
rechargeable Lithium-ion type battery.

NOTE

The car cannot be started if the hybrid bat-
tery is discharged.

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 is not possible. In order for the
hybrid battery to be charged, the starter bat-
tery must have a certain state of charge.

WARNING

The hybrid battery must only be replaced

by a workshop - an authorised Volvo work-

shop is recommended.

The service life and capacity of the
hybrid battery

The capacity of the hybrid battery diminishes
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.

Coolant

The hybrid battery's cooling system has a sep-
arate expansion tank.

IMPORTANT

The hybrid battery's coolant must only be
topped up by a workshop - an authorised
Volvo workshop is recommended.
