Refilling coolant

Coolant helps keep the combustion engine at
the right operating temperature. The heat trans-
ferred from the engine to the coolant can be
used to warm the passenger compartment.

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 sys-
tem, there could be something wrong with the
cooling system and starting 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 expansion tank

cap slowly to relieve overpressure.

Coolant expansion tank.

MAINTENANCE AND SERVICE

610

Lift the rubber strip by pressing it inward into
the engine compartment.

Remove the plastic cover by folding out the
catch and lifting the cover upward.

Unscrew the expansion tank cap and fill
coolant as needed. The level should be
between the MIN and MAX marks on the
expansion tank.

CAUTION

•

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

•

Use premixed coolant according to Vol-
vo's recommendations. If concentrated
coolant is used, make sure that the cool-
ant 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 cool-
ant when replacing larger components in
the cooling system.

•

Never run the engine unless the cooling
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.

Never touch the bulb glass with your bare fin-
gers. Grease and oils from your fingers vapor-
ize in the heat and will leave a deposit on the
reflector, which may damage it.

NOTE

If the error message persists after the defec-
tive bulb has been replaced, we recommend a
visit to an authorized Volvo workshop.

NOTE

Exterior lighting such as headlights and tail-
lights may develop temporary condensation
on the inside of the lens. This is normal. All
exterior lighting is designed to resist this.
Condensation is normally vented out of the
lamp housing once the light has been lit for
some period of time.

NOTE

Bulbs for active curve lighting* contain traces
of mercury and should therefore always be
submitted to a certified Volvo service techni-
cian.

Start battery

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

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

The start battery should only be replaced by a
workshop

The vehicle has a voltage-regulated alternating
current generator.

The start battery is a 12 V battery, designed for
the carbon dioxide reducing functions Start/Stop
and regenerative charging, and to support the
functionality of the car's different systems.

The service life and performance of the start bat-
tery are affected by factors such as driving style,
driving conditions, climate, battery discharges,
number of starts, etc.

•

Never disconnect the start battery while the
engine is running.

•

Make sure the cables to the start 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.

Connection points

WARNING

PROPOSITION 65 WARNING

Battery posts, terminals, and related accesso-

ries contain lead and lead compounds, chemi-

cals known to the state of California to cause

cancer and reproductive harm. Wash hands

after handling.

Use the vehicle's connection points in the engine
compartment to connect an external start battery
or battery charger.

The battery terminals on the car's start battery in
the luggage/cargo area must not be used.

If the start battery is being charged, the support
battery will also be charged.

Positive connection point

Negative connection point

An authorized Volvo workshop is recommended.

MAINTENANCE AND SERVICE

}}

619

CAUTION

Only a modern battery charger with controlled
charge voltage should be used to charge the
starter battery and support battery. The rapid
charging function should not be used as this
could damage the battery.

CAUTION

Failure to observe the following could cause
the infotainment energy save mode to tempo-
rarily stop working and/or a message in the
driver's display regarding the state of charge
of the starter battery may be temporarily
incorrect after an external starter battery or
battery charger has been connected:

•

The negative battery terminal of the vehi-
cle's starter battery must never be used
to connect an external starter battery or
battery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.

NOTE

If the starter battery becomes discharged too
many times, it will shorten its service life.

The service life of the starter battery is affec-
ted by several factors, such as driving condi-
tions and climate. The starting capacity of the
battery reduces gradually over time. The bat-
tery must therefore be recharged if the vehi-
cle is not used or a long period of time or if it
is only driven short distances. Severe cold fur-
ther limits the starting capacity.

To keep the starter battery in a 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 start battery is located in the cargo compartment.

WARNING

If the starter battery is disconnected, the func-

tion for automatic opening and closing must

be reset to function correctly. A reset is

required in order for the pinch protection to

work.

Support battery

In addition to the start battery, vehicles equipped
with the Start/Stop function also have a support
battery.

Vehicles with the Start/Stop function are equip-
ped with two 12-volt batteries

‒ a heavy-duty

start battery and a support battery that provides
extra current during the Start/Stop function's
start sequence.

The support battery is located in a box next to the spring
strut in the engine compartment.

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 workshop

‒

an authorized Volvo workshop is recommended.

CAUTION

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

•

MAINTENANCE AND SERVICE

622

NOTE

If the starter battery is 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 insufficient 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 bat-
tery to be charged with a battery charger, it is
advisable to temporarily deactivate the
Start/Stop function until the battery has been
recharged by the vehicle. At an ambient tem-
perature of about +15°C (about 60°F), the
battery must be charged by the vehicle for at
least one hour. At lower ambient tempera-
tures, the charging time can increase to
3-4 hours. It is advisable to charge the battery
with an external battery charger.
