Coolant

The coolant helps ensure that excess heat is
distributed in the circuit in order to, for exam-
ple, warm up the start battery or provide
heating to the passenger compartment.

To avoid deterioration of the cooling system,
engine trouble, etc., only approved Volvo cool-
ant should be used.

Recommended grade:

 Volvo-approved pre-

mixed coolant. If concentrated coolant is used,
mix with 50% water of acceptable quality (i.e.
not salt water, etc.). Consult a Volvo retailer if
you have any questions.

To avoid deterioration of the cooling system,
engine trouble, etc., only approved Volvo cool-
ant should be used.

WARNING

Coolant is hazardous if ingested and could

cause damage to organs (kidneys). The

product contains ethylene glycol, inhibitor,

water, etc.

Refilling coolant

When refilling coolant, follow the instructions
on the package. Never fill the cooling system
with only water. The risk of freezing is
increased with too low or too high amounts
of coolant.

If there is coolant under the vehicle, smoke
from the cooling system, or if more than
2 liters (about 2 quarts) of coolant has been
added to the system, there could be some-
thing wrong with the cooling system and star-
ting the vehicle could damage the engine. Call
a tow truck and do not attempt to start the
engine.

WARNING

The coolant may be very hot. Never

unscrew the cap when the coolant is hot. If

coolant must be filled, unscrew the expan-

sion tank cap slowly to relieve overpres-

sure.

Coolant expansion tank, left-hand drive vehicle

Unscrew the cover in the plastic covering.

Unscrew the expansion tank cap and fill
coolant as needed. The level should not
exceed the yellow 

MAX

 mark inside the

expansion tank.

Put the components back in place in the
reverse order.

CAUTION

•

Do not ingest the contents. May cause
damage to organs (kidneys).

•

Use premixed coolant according to
Volvo's recommendations. If concen-
trated coolant is used, make sure that
the coolant mixture is 50% coolant
and 50% water of acceptable quality.

•

Do not mix different types of coolant.

•

To help ensure sufficient corrosion pro-
tection in the system, only use new
coolant when replacing larger compo-
nents in the cooling system.

•

Never run the engine unless the cool-
ing system is properly filled. An
improperly filled cooling system could
lead to high temperatures and cracks
in the cylinder heads.

•

High levels of chlorine, chlorides and
other salts may cause corrosion in the
cooling system.

Starter battery

The starter battery is used to start the electri-
cal system and power the starter motor and
other electrical equipment in the vehicle.

The vehicle has a single-pole electrical system
that uses the chassis and engine mount as
conductors.

The vehicle has a voltage-regulated alternating
current generator.

The starter battery is a 12 V battery, dimen-
sioned for the carbon dioxide-reducing func-
tions Start/Stop and regenerative charging
and to support the function of the vehicle's
various systems.

The service life and performance of the starter
battery are affected by factors such as driving
style, driving conditions, climate, battery dis-
charges, number of starts, etc.

•

Never disconnect the starter battery while
the engine is running.

•

Make sure the cables to the starter battery
are correctly connected and the clamps
are securely tightened.

WARNING

•

Batteries generate hydrogen gas,
which is flammable and explosive.

•

Do not connect the jumper cable to
any part of the fuel system or to any
moving parts. Avoid touching hot
manifolds.

•

Battery fluid contains sulfuric acid. Do
not allow battery fluid to contact eyes,
skin, fabrics or painted surfaces.

•

If contact occurs, flush the affected
area immediately with water. Obtain
medical help immediately if eyes are
affected.

•

Never expose the battery to open flame
or electric spark. Do not smoke near
the battery. Failure to follow the
instructions for jump starting can lead
to injury.

Starter battery service life and
capacity

The service life of the starter battery is affec-
ted by several factors, such as number of
starts, battery discharges, driving style, driving
conditions, climate, etc. The starting capacity
of the battery reduces gradually over time. The
battery must therefore be recharged if the
vehicle is not used for a long period of time or
if it is only driven short distances. Severe cold

further limits starting capacity. If the starter
battery becomes discharged too many times,
its service life will be shortened.

To help keep the starter battery in good condi-
tion, the vehicle should be driven at least
15 minutes per week or the battery should be
connected to a battery charger with automatic
trickle charging. A starter battery that is
always kept fully charged has the maximum
service life.

Location

The starter battery is located in the cargo compart-

ment.

MAINTENANCE AND SERVICE

601

WARNING

If the starter battery is disconnected, the

function for automatic opening and closing

must be reset to function correctly. A reset

is required in order for the pinch protection

to work.

CAUTION

On certain models, the battery is secured
with a tensioning strap. Make sure that the
tensioning strap is always securely tight-
ened.

Support battery

Vehicles with the Start/Stop function are
equipped with two batteries – a more power-
ful 12 V start battery and a support battery
that provides stronger current during the
function's start sequence.

The 12 V support battery is located in a box next to

the spring strut in the engine compartment.

If the vehicle is instead equipped with a 48 V support

battery, it is located under the cargo compartment.

The box over the 48 V support battery may only be

removed by an authorized workshop.

WARNING

High voltage may be dangerous if handled

incorrectly. Do not touch anything on bat-

teries that is not clearly described in this

•

Never use a 48 V support battery to
jump start the vehicle.

•

External electrical equipment may not
under any circumstance be connected
to the 48 V battery.

•

Only a workshop may replace or per-
form service on the 48 V battery – an
authorized Volvo workshop is recom-
mended.

NOTE

•

The higher the current consumption in
the vehicle, the more the alternator has
to work and the batteries have to be
charged = increased fuel consumption.

•

When the starter battery capacity has
dropped below the lowest permissible
level, the Start/Stop function is disen-
gaged.

When the Start/Stop function is temporarily
reduced due to high current consumption:

•

The engine will auto-start, even if the
driver does not lift their foot from the
brake pedal.

The support battery does not normally require
more service than the start battery. If you have
any questions or concerns, consult a work-
shop 

‒ 

an authorized Volvo workshop is rec-

ommended.

MAINTENANCE AND SERVICE

603

CAUTION

If the following is not observed, the Start/
Stop function may temporarily stop work-
ing after connection of an external starter
battery or battery charger:

•

The negative battery terminal of the
vehicle's starter battery must 

never

 be

used to connect an external starter
battery or battery charger – only the

vehicle's negative charging point

should be used as a grounding point.

NOTE

If the starter battery has been discharged
to the extent that the vehicle does not have
normal electrical functions and the engine
must then be jump-started with an external
battery or a battery charger, the Start/Stop
function may remain activated. If the Start/
Stop function shortly thereafter auto-stops
the engine, there is a huge risk that auto-
start of the engine will fail due to insuffi-
cient battery capacity since the battery had
not had time to recharge.

If the vehicle has been jump-started or if
there has not been enough time for the
battery to be charged with a battery
charger, the Start/Stop function should be
temporarily deactivated until the battery
has been recharged by the vehicle. At an
ambient temperature of about +15°C
(about 60°F), the battery must be charged
by the vehicle for at least one hour. At
lower ambient temperatures, the charging
time can increase to 3-4 hours. It is advisa-
ble to charge the battery with an external
battery charger.

Fuses and fuseboxes

All electrical functions and components are
protected by a number of fuses in order to
protect the vehicle's electrical system from
damage by short circuiting or overloading.

WARNING

Never use a foreign object or a fuse with a

higher amperage than that specified to

replace a fuse. This could cause significant

damage to the electrical system and possi-

bly lead to a fire.

If any electrical component or function is not
responding, the component may have blown a
fuse due to temporary overload. If the same
fuse blows repeatedly, there may be a prob-
lem with the component. Volvo recommends
contacting an authorized Volvo workshop to
have the component checked.
