Long-term storage of vehicles with

hybrid batteries

To minimise hybrid battery degradation dur-
ing prolonged storage (longer than 1 month)
of the vehicle a charge level of approximately
25% is recommended as indicated on the
driver display.

Proceed as follows:

1. If the state of charge is high – run the car

until approx. 25% remains. If the state of
charge is low – charge the battery until a
level of approx. 25% is reached.

2. If storage has lasted longer than 6 months

or the hybrid battery charge level is signifi-
cantly lower than 25% – charge the bat-
tery to approx. 25% again to compensate
for the natural self-discharge that occurred
during the prolonged storage. Continu-
ously check the charge level in the driver
display.

NOTE

Choose the coolest location possible for
the vehicle in order to minimise aging of
the battery during long-term storage. Dur-
ing summer the vehicle should preferably
remain indoors or outdoors in the shade,
depending on where the temperature is
lowest.

Starting the car

The car is started using the start knob in the
tunnel console when the remote control key
is in the passenger compartment.

Start knob in the tunnel console.

WARNING

Before starting:

•

Fasten the seatbelt.

•

Adjust the seat, steering wheel and
mirrors.

•

Make sure that the brake pedal can be
fully depressed.

The remote control key is not physically used
when starting the car since it is equipped with
support for keyless starting (Passive start).

To start the car:

IMPORTANT

The car cannot be started if the charging
cable is still engaged. Make sure the
charging cable is removed from the charg-
ing input socket before the starting the car.

1. The remote control key must be inside the

car. For cars with Passive Start, the key
needs to be located in the front part of the
passenger compartment. With the option
for keyless locking/unlocking

*

 of the car,

the key can be anywhere in the car.

2. Hold the brake pedal depressed

1

 fully. For

cars with automatic gear changing, make
sure that gear position 

P

 or 

N

 is selected.

For cars with a manual gearbox, make
sure that the gear lever is in neutral posi-
tion or that the clutch pedal is depressed.

3. Turn the start knob clockwise and then

release it. The control automatically
returns to its starting position.

When the engine is started, the starter motor
works until the engine is started or until its
overheating protection triggers.

When starting in normal conditions, the car's
electric drive motor is prioritised - the petrol

engine remains switched off. This means that
after the start knob has been turned clock-
wise, the electric motor has ”started” and the
car is ready to drive. A started car is indicated
by the driver display's indicator lamps extin-
guishing and its preset theme illuminating.

However there are situations where the petrol
engine is started instead e.g. in the event of
the temperature being too low or if the hybrid
battery needs charging.

Error messages

If the 

Car key not found

 message is shown in

the driver display when starting, place the
remote control key by the backup reader. Then
try to start the car again.

Backup reader's location in the tunnel console.

NOTE

When the remote control key is positioned
by the backup reader, make sure that there
are no car keys, metal objects or electronic
apparatus by the backup reader, (e.g.
mobile phones, tablets, laptops or charg-
ers). Several car keys close to one another
by the backup reader may cause interfer-
ence with each other.

If the message

System check, wait

is shown in the driver display when starting,
wait until the message disappears and then
try to start the car again.

IMPORTANT

If the engine fails to start after 3 attempts -
wait for 3 minutes before making a further
attempt. Starting capacity increases if the
battery is allowed to recover.

NOTE

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

WARNING

Never

 remove the remote control key from

the car while driving.

WARNING

Always take the remote control key out

from the car when leaving the car and

make sure the car's electrical system is in

ignition position 

0

 - especially if there are

children in the car.

NOTE

The idling speed can be noticeably higher
than normal for certain engine types during
cold starting. This is done in order that the
emissions system can reach normal oper-
ating temperature as quickly as possible,
which minimises exhaust emissions and
protects the environment.

Alcohol lock

*

The function of the alcohol lock is to prevent
the car from being driven by individuals under
the influence of alcohol. Before the engine
can be started the driver must take a breath
test that verifies that he/she is not under the
influence of alcohol. Alcohol lock calibration
takes place in accordance with each market's
limit value in force for driving legally.

The car has an interface for the electrical con-
nection of the different makes and models of
alcohol lock recommended by Volvo. The
interface facilitates alcohol lock connection,
and gives the option of an integrated function
including messages related to the alcohol lock
in the car's main display. For information
about a specific alcohol lock, please refer to
the owner's manual from the respective alco-
hol lock manufacturer.

WARNING

The alcohol lock is an aid and does not

exempt the driver from responsibility. It is

always the responsibility of the driver to be

sober and to drive the car safely.

Brake functions

The car's brakes are used to reduce the
speed or prevent the car from rolling.

In addition to the foot brake and parking
brake, the car is equipped with several auto-
matic brake assist functions. These can assist
the driver by not needing to keep his/her foot
on the brake pedal when at a traffic light, or
when starting on an uphill gradient.

Depending on the car's equipment, the follow-
ing auto braking functions are available:

•

Automatic brake when stationary (Auto
Hold)

•

Hill start assist (Hill Start Assist)

•

Auto braking after a collision

 (p. 352)

Foot brake

The foot brake is part of the brake system.

The car is equipped with two brake circuits. If
a brake circuit is damaged, the brake pedal
may engage deeper. Higher pressure on the
pedal will therefore be needed to produce the
normal braking effect.

WARNING

The brake servo only works when the elec-

tric motor or internal combustion engine is

running.

If the foot brake is used when the car is
switched off, the brake pedal needs to be
depressed passed the normal braking position
using a higher pressure to brake the car.

In very hilly terrain or when driving with a
heavy load the brakes can be relieved by using
engine braking in gearshift mode 

B

.

Anti-lock braking system

The car has anti-lock brakes (ABS

2

), which

prevents the wheels from locking while brak-
ing and allows maintained steering control.
Vibration may be felt in the brake pedal when
this is engaged and this is normal.

A short test of the ABS system is made auto-
matically after the car has been started when
the driver releases the brake pedal. A further

2

automatic test of the system may be made at
low speed. The test may be felt as pulses in
the brake pedal.

Light braking charges the hybrid
battery

The electric motor's engine brake is used dur-
ing light braking. The car's kinetic energy is
then converted to electrical energy instead,
which is used to charge the hybrid battery.
Battery charging with electric motor braking is
indicated in the driver display.

The driver display indicates charging during electric

motor braking.

This function is active in the speed interval
150-5 km/h (93-3 mph). During heavier brak-
ing, as well as outside the speed interval, brak-
ing is supplemented by the hydraulic brake
system. The driver's display shows this by the
indicator being down in the red zone.

Symbols in the driver display

Symbol Specification

Check the brake fluid level. If the
level is low, fill with brake fluid
and check for the cause of the
brake fluid loss.

Fault in pedal sensor.

Constant glow for 2 seconds
when the engine is started: Auto-
matic function check.

Constant glow for more than 2
seconds: Fault in the ABS sys-
tem. The car's normal brake sys-
tem is still working, but without
the ABS function.

If the message 

Brake pedal

Characteristics changed Serv-
ice required

 is shown, the sys-

tem for "Brake-by-wire" is disen-
gaged. The brake pedal needs to
be depressed passed the normal
braking position using a higher
pressure to brake the car.

WARNING

If both the warning lamps for brake fault

and ABS fault illuminate at the same time,

a fault has occurred in the brake system.

•

If the level in the brake fluid reservoir is
normal at this stage, drive carefully to
the nearest workshop and have the
brake system checked - an authorised
Volvo workshop is recommended.

•

If the brake fluid is below the 

MIN

 level

in the brake fluid reservoir, do not drive
further before topping up the brake
fluid. The reason for the loss of brake
fluid must be investigated.

Brake assistance

The brake assist system (BAS

3

) helps to

increase brake force during braking, and can
thereby shorten the braking distance.

The system detects the way in which the
driver brakes and increases brake force where
necessary. The brake force can be boosted up
to the level when the ABS system is engaged.

Related information

•

Foot brake (p. 455)

Braking on wet roads

When driving for a prolonged period of time
in heavy rain without braking, the braking
effect may be delayed slightly when next
using the brakes.

This may also be the case after a car wash. It
is then necessary to depress the brake pedal
more forcefully. You should therefore maintain
a greater distance to the vehicles in front.

Brake the car firmly after driving on wet roads
or using a car wash. This warms up the brake
discs, enabling them to dry faster and protect-
ing them against corrosion. Bear in mind the
current traffic situation when braking.

Braking on gritted roads (p. 457)

Braking on gritted roads

When driving on salted roads, a layer of salt
may form on the brake discs and brake lin-
ings.

This may extend braking distance. You should
therefore maintain a greater safety distance to
vehicles in front. In addition, make sure you do
the following:

•

Brake now and again to remove any layer
of salt. Make sure that other road users
are not put at risk by the braking.

•

Gently depress the brake pedal after fin-
ishing driving and before starting your next
trip.

Brake system maintenance

Check brake system components regularly
for wear.

To keep the car as safe and reliable as possi-
ble, follow the Volvo service intervals as speci-
fied in the Service and Warranty Booklet. After
replacing brake linings and brake discs, brak-
ing effect is only adapted after they have been
"worn in" for a few hundred kilometres (miles).
Compensate for the reduced braking effect by
depressing the brake pedal harder. Volvo rec-
ommends only fitting brake linings that are
approved for your Volvo.

IMPORTANT

The wear on the brake system's compo-
nents must be checked regularly.

Contact a workshop for information about
the procedure or engage a workshop to
carry out the inspection - an authorised
Volvo workshop is recommended.

Foot brake (p. 455)

Parking brake

The parking brake prevents the car from roll-
ing away from stationary by means of
mechanically locking/blocking two wheels.

The control for the parking brake is located in the

tunnel console between the seats.

A faint electric motor noise can be heard when
the electrically-operated parking brake is
being applied. The noise can also be heard
during the automatic function checking of the
parking brake.

If the car is stationary when the parking brake
is activated, it only acts on the rear wheels. If
it is activated when the car is moving then the
normal foot brake is used, i.e. the brake acts
on all four wheels. Brake function changes
over to the rear wheels when the car is almost
stationary.

Automatic braking when stationary

Automatic brake when stationary (Auto hold)
means that the driver can release the brake
pedal while maintaining braking effect when
the car has stopped at traffic lights or a junc-
tion.

When the car has stopped, the brakes are
activated automatically. The function can use
either foot brake or parking brake to hold the
car stationary and it works on all gradients.
When driving off, the brakes are released
automatically if the driver is wearing the seat-
belt and/or the driver's door is closed.

NOTE

When braking to a standstill on an uphill or
downhill slope, the brake pedal should be
depressed a little harder before being
released to ensure the car does not roll.

The parking brake is activated if

•

the car is switched off

•

the driver's door is opened

•

the driver's seatbelt is unbuckled

•

the car has been stationary for a longer
time (5-10 minutes).
