limitations

Blind sectors

There are "blind" sectors between the cameras' fields

of vision.

With the Park Assist Camera's 360° view

*

selected, objects/obstacles may not be
detected if they are located in the "joints"
where the edges of the individual camera
views meet.

WARNING

Even if it seems as though only a fairly

small section of the screen image is

obstructed, this may mean that a relatively

large sector is hidden and obstacles there

may not be detected until they are very

near the vehicle.

Lighting conditions

The camera image is automatically adjusted
according to the current lighting conditions.
This means that the brightness and quality of
the image may vary slightly. Poor lighting con-
ditions may result in reduced image quality.

NOTE

A bike carrier and other accessories moun-
ted on the rear of the vehicle can obscure
the camera's view.

Starting the vehicle

The vehicle can be started using the start
knob in the tunnel console when the remote
key is in the passenger compartment.

Start knob in the tunnel console.

WARNING

Before starting:

•

Buckle your seat belt.

•

Adjust the seat, steering wheel and
mirrors.

•

Make sure you can fully depress the
brake pedal.

The remote key is not physically used to start
the ignition because the vehicle is equipped
with the keyless Passive Start system.

To start the vehicle:

1. The remote key must be inside the vehicle.

For vehicles with Passive Start, the key
must be in the front section of the passen-
ger compartment. With the optional key-
less locking/unlocking function

*

, the key

can be anywhere in the vehicle.

2. Press and hold down the brake pedal

1

 as

far as possible.

3. Turn the start knob clockwise and release.

The control will automatically return to the
original position.

WARNING

•

Never use more than one inlay mat at a
time on the driver's floor. If any other
type of floor mat is used, remove the
original mat from the driver's seat floor
before driving. All types of mats must
be securely anchored in the attach-
ment points in the floor. Make sure the
floor mat does not impede the move-
ment of the brake pedal or accelerator
pedal in any way, as this could be a
serious safety hazard.

•

Volvo's floor mats are specially manu-
factured for your vehicle. They must be
properly secured in the attachment
points in the floor to help ensure they
cannot slide and become trapped
under the pedals.

The starter motor will crank until the engine
starts or until overheating protection is trig-
gered.

Error messages

If the 

Vehicle key not found

 message is

shown in the instrument panel at start, place
the remote key at the backup reader and then
make a new start attempt.

Location of the backup reader in the tunnel console.

NOTE

When the remote key is placed in the
backup reader, make sure that no other
vehicle keys, metal objects or electronic
devices (e.g. cellular phones, tablets, lap-
tops or chargers) are in the backup reader.
Multiple vehicle keys close to each other in
the backup reader can disrupt their func-
tionality.

CAUTION

If the engine has not responded after 3
attempts – wait for 3 minutes before star-
ting a new attempt. Starting capability
increases if the starter battery is given time
to recover.

WARNING

Never

 remove the remote control key from

the vehicle while driving or the vehicle is

being towed.

WARNING

•

Always remove the remote key from
the passenger compartment when you
leave the vehicle and make sure the
ignition is in mode 

0

.

•

Always put the gear selector in 

P

 and

apply the parking brake before leaving
the vehicle. Never leave the vehicle
unsupervised while the engine is run-
ning.

•

Always open the garage door fully and
make sure that ventilation is very good
before starting the engine in a garage.
The exhaust fumes produced by the
vehicle contain carbon monoxide,
which is invisible and odorless but very
toxic.

CAUTION

•

When starting in cold weather, the
automatic transmission may shift up at
slightly higher engine speeds than nor-
mal until the automatic transmission
fluid reaches normal operating tem-
perature.

•

Do not race a cold engine immediately
after starting. This could prevent fluids
from properly lubricating vital compo-
nents in the engine before it has
reached the proper operating tempera-
ture.

•

The engine should be idling when the
gear selector is moved. Never acceler-
ate until the gear is fully engaged.
Accelerating rapidly before a gear is
properly engaged could lead to harder
wear of components.

•

To help prevent the transmission oil
from overheating, select 

P

 or 

N

 when

idling at a standstill for prolonged peri-
ods of time.

STARTING AND DRIVING

398

NOTE

With a cold start, idling speed may be con-
siderably higher than normal for certain
engine types. This is done to get the emis-
sions system up to normal operating tem-
perature as quickly as possible, which min-
imizes exhaust emissions and protects the
environment.

Brake functions

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

In addition to the wheel brakes and parking
brakes, the vehicle is also equipped with a
number of automatic brake assist functions.
These systems provide assistance by e.g. the
driver not needing to depress the brake pedal
at a traffic light or when starting up a hill.

Depending on how the vehicle is equipped,
the following brake assist functions may be
included:

•

Auto-hold brake function at a standstill
(Auto Hold)

•

Hill Start Assist (Hill Start Assist)

•

Braking assist after a collision

Brakes

The brake pedal is used to apply the vehicle's
regular brakes, which are part of the brake
system.

The vehicle is equipped with two brake cir-
cuits. If one brake circuit is damaged, the
brake pedal may go down further when
depressed. More pressure will then be
required from the driver for normal braking
effect.

The driver's pressure on the brake pedal is
enhanced by a power braking function.

WARNING

Power braking only functions if the engine

is running.

If the brake pedal is used when the engine is
turned off, the pedal will feel stiffer than usual
and greater pressure must be applied to brake
the vehicle.

In very hilly areas or when driving with a heavy
load, manual gear shifting can be used to aug-
ment the brakes with engine braking. Engine
braking is most effective if the same gear is
used both uphill and downhill.

Anti-lock brakes

The vehicle is equipped with an Anti-lock
Braking System (ABS

2

), which helps prevent

the wheels from locking and helps maintain
steering control when braking. Vibrations may
be felt from the brake pedal when ABS is
operating, which is normal.

After the vehicle is started, a brief test of the
ABS system is automatically performed when
the driver releases the brake pedal. An addi-
tional automatic test of the system may be
performed when the vehicle is traveling at a
low speed. During the test, the brake pedal
may feel as though it is pulsating.

If the brake fluid reservoir level is nor-
mal when this occurs, drive carefully to
the nearest workshop to have the
brake system checked - an authorized
Volvo workshop is recommended.

•

If the brake fluid has fallen below the

MIN

 level in the brake fluid reservoir,

the vehicle should not be driven until
the brake fluid has been filled. The rea-
son for the brake fluid loss must be
checked.

Brake Assist System

The brake enhancing system, (BAS

3

), helps

increase braking force and can thereby
reduce braking distance.

The system monitors the driver's braking hab-
its and increases braking force when neces-
sary. Braking force can be increased up to the
point at which the ABS intervenes.

NOTE

When BAS is activated, depress and hold
down the brake pedal as long as needed.

Braking on wet roads

Prolonged driving in heavy rain without brak-
ing may cause braking effect to be slightly
delayed the first time the brakes are applied.

This may also occur after washing the vehicle.
It will then be necessary to apply greater pres-
sure to the brake pedal. You should therefore
maintain a greater distance to the vehicle
ahead.

Firmly apply the brakes after washing the
vehicle or driving on wet roads. This helps
warm up the brake discs, enabling them to dry
more quickly and protecting them against cor-
rosion. Consider the current traffic situation
when braking.

Braking on salted roads (p. 403)

Braking on salted roads

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

This could increase stopping distance. Main-
tain an extra large safety distance to the vehi-
cle ahead. Make sure to also:

•

Apply the brakes from time to time to help
remove salt. Make sure braking does not
pose a risk to any other road users.

•

Gently apply the brakes when you have
finished driving and before driving again.

Maintenance of the brake system

Regularly check the brake system compo-
nents for wear.

To keep the vehicle as safe and reliable as
possible, follow the Volvo service schedule
specified in the Warranty and Maintenance
Records Information booklet. After replacing
brake pads and brake discs, braking effect is
not adapted until they are "broken in" by driv-
ing a few hundred kilometers (miles). Com-
pensate for the reduced braking effect by
applying greater pressure to the brake pedal.
Volvo recommends only using brake pads
approved for your Volvo.

CAUTION

The brake system's components should be
regularly checked for wear.

Contact a workshop for advice on how to
do this or let a workshop perform the
inspection - an authorized Volvo workshop
is recommended.

Parking brake

The parking brake helps keep the vehicle sta-
tionary by mechanically locking two wheels.

The parking brake controls are located in the tunnel

console between the seats.

When the electric parking brake is being
applied, a faint sound can be heard from the
brake's electric motor. This sound can also be
heard during the automatic function check of
the parking brake.

If the vehicle is stationary when the parking
brake is activated, it will only be applied to the
rear wheels. If it is activated while the vehicle
is moving, the normal brakes will be used on
all four wheels. Braking will be transferred to
only the rear wheels when the vehicle is
almost stopped.

Auto-hold brakes

With the Auto-hold brake function, the driver
can release the brake pedal and the brakes
will remain applied, for example, when the
vehicle has stopped at a traffic light or inter-
section.

When the vehicle stops, the brakes are acti-
vated automatically. The function can use
either the normal brakes or the parking brakes
to keep the vehicle stationary and works on
flat surfaces or hills. If the driver has their seat
belt fastened and/or if the driver's door is
closed, the brakes will disengage automati-
cally when the vehicle starts driving.

NOTE

When braking to a stop on an uphill or
downhill gradient, depress the brake pedal
with slightly more force than usual before
releasing to ensure that the vehicle cannot
move at all.

The parking brake is activated if

•

the vehicle is switched off.

•

the driver's door is opened

•
