Volvo XC60 (2019 year). Instruction - part 19

Auto-hold braking with Pilot Assist

Pilot Assist has a special braking function in
slow traffic and at a standstill.

Braking function in slow traffic and at a
standstill

In slow-moving, stop-and-go traffic or when stop-
ped at a traffic light, driving will resume automati-
cally if the vehicle is stopped for less than
approx. 3 seconds. If it takes more than 3 sec-
onds for the vehicle ahead to begin moving again,
Pilot Assist will go into standby mode and the
Auto-hold brake function will activate.

–

Pilot Assist can be reactivated by:

•

Pressing the

button on the steering

wheel keypad.

•

Pressing the accelerator pedal.

> Pilot Assist will resume following the vehi-

cle ahead if it begins to move within
approx. 6 seconds.

Pilot Assist can keep the vehicle stationary
for no more than 5 minutes – after that time
the parking brake is applied and the function
is deactivated.

The parking brake must be released before
Pilot Assist can be reactivated.

Deactivation of the Auto-hold brake function

In certain situations, Auto-hold will be deactivated
when the vehicle is at a standstill and Pilot Assist
will go into standby mode. This means that the
brakes will be released and the vehicle could
begin to roll. The driver must actively apply the
brakes to keep the vehicle stationary.

This can occur if:

•

the driver depresses the brake pedal

•

the parking brake is applied

•

the gear selector is moved to the P, N or R
positions

•

the driver puts Pilot Assist in standby mode.

Auto Activate Parking Brake

In certain situations, the parking brake will be
applied to keep the vehicle at a standstill.

This occurs if Pilot Assist is keeping the vehicle
stationary using the brakes and:

•

the driver opens the door or unbuckles
his/her seat belt

•

Pilot Assist has kept the vehicle at a stand-
still for more than approx. 5 minutes

•

the brakes overheat

•

the driver switches off the engine manually.

Pilot Assist limitations

Pilot Assist functionality may be reduced in cer-
tain situations.

Pilot Assist is a driver support function designed
to simplify driving and assist the driver in many
situations. However, the driver is always responsi-
ble for maintaining a suitable distance to vehicles
or objects around it and ensuring that the vehicle
is correctly positioned in the traffic lane.

WARNING

In some situations, Pilot Assist may have trou-

ble helping the driver properly or may be

deactivated automatically – we advise against

using Pilot Assist in such cases. Examples of

such situations include:

•

the lane markings are worn, missing or
cross each other.

•

lane division is unclear, for example, when
the lanes divide or merge or at exits or
when there are multiple sets of markings.

•

edges or other lines than lane markings
are present on or near the road, e.g.
curbs, joints or repairs to the road sur-
face, edges of barriers, roadside edges or
strong shadows.

•

the lane is narrow or winding.

•

the lane contains ridges or holes.

•

weather conditions are poor, e.g. rain,
snow or fog or slush or reduced visibility
with poor light conditions, backlighting,
wet road surface, etc.

The driver should also note that Pilot Assist

has the following limitations:

•

High curbs, roadside barriers, temporary
obstacles (traffic cones, safety barriers,
etc.) are not detected. Alternatively, they
may be detected incorrectly as lane mark-
ings, with a subsequent risk of contact
between the vehicle and such obstacles.

The driver is responsible for ensuring that
the vehicle maintains a suitable distance
from such obstacles.

•

The camera and radar sensors do not
have the capacity to detect all oncoming
objects and obstacles in traffic environ-
ments, e.g. potholes, stationary obstacles
or objects that completely or partially
block the route.

•

Pilot Assist does not "see" pedestrians,
animals, etc.

•

The recommended steering input is lim-
ited in force, which means that it cannot
always help the driver to steer and keep
the vehicle within the lane.

•

In vehicles equipped with Sensus
Navigation*, the function is able to use
information from map data, which could
cause variations in performance.

•

Pilot Assist is switched off if the power
steering is working with reduced power -
e.g. during cooling due to overheating
(see section "Speed-dependent steering
force").

The driver can always correct or adjust steering
assistance provided by Pilot Assist by turning the
steering wheel to the desired position.

DRIVER SUPPORT

* Option/accessory.

326

Steep roads and/or heavy loads

Pilot Assist is primarily intended to be driven on
flat roads. The function may not be able to main-
tain the correct time interval to the vehicle ahead
when driving down steep hills. The driver should
be extra attentive and prepared to apply the
brakes.

•

Do not use Pilot Assist if the vehicle is carry-
ing a heavy load or towing a trailer.

Pilot Assist cannot be activated if a trailer,
bike carrier or similar is connected to the
vehicle electrical system.

Other limitations

•

The

Off Road

drive mode cannot be

selected when Pilot Assist is activated.

The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

Radar sensor limitations

The radar sensor used by several of the driver
support functions has certain limitations, which
also affect the functions using the radar sensor.

Obstructed camera

The area marked in the illustration must be kept free of
decals, objects, solar film, etc.

The radar sensor is located on the upper interior
section of the windshield along with the camera.

Do not place, affix or mount anything on the
inside or outside of the windshield, or in front
of or around the camera and radar unit – this
could disrupt camera and radar-based func-
tions.

It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.

If this symbol and the message
"

Windscreen sensor

Sensor

blocked, see Owner's manual

" is

displayed in the instrument panel, it

means that the camera and radar sensor are
unable to detect other vehicles, cyclists, pedes-
trians and large animals in front of the vehicle
and that the vehicle's camera and radar-based
functions may be obstructed, reduced, completely
disabled or providing inaccurate responses.

The following table shows some of the situations that can cause the message to be displayed, and suggested actions:

Cause

Action

The area of the windshield in front of the camera/radar sensor is dirty or
covered by ice or snow.

Clean the windshield in front of the camera/radar sensor and remove dirt, ice
and snow.

Thick fog, heavy rain or snow is blocking the radar signals or the camera's
range of visibility.

No action. Heavy precipitation may sometimes prevent the camera/radar sensor
from functioning.

Note: This illustration is general and details may vary depending on model.

DRIVER SUPPORT

330

Cause

Action

Water or snow is spraying/swirling up and blocking the radar signals or
the camera's range of visibility.

No action. Very wet or snow-covered roads may sometimes prevent the cam-
era/radar sensor from functioning.

There is dirt between the inside of the windshield and the camera/radar
sensor.

Consult a workshop to have the area of the windshield on the inside of the cam-
era's casing cleaned. An authorized Volvo workshop is recommended.

Keep the windshield in front of the camera
and radar unit clean.

Vehicle speed

The radar sensor's ability to detect a vehicle
ahead is significantly reduced if:

•

the speed of the vehicle ahead differs greatly
from your vehicle's speed

Limited field of vision

The radar sensor has a limited field of vision. In
some situations, it may detect a vehicle later than
expected or not at all.

The radar sensor's field of vision.

The radar sensor's detection of vehicles very
close to your vehicle may be delayed in cer-
tain situations, e.g. if a vehicle pulls in

between your vehicle and the vehicle directly
ahead.
Small vehicles, such as motorcycles, or vehi-
cles that are not driving in the center of the
lane may remain undetected.
In curves, the radar may detect the wrong
vehicle or lose sight of a target vehicle.

Low trailers

Low trailer in the radar shadow.

Low trailers may also be difficult or even impossi-
ble for the radar to detect. The driver should be
extra alert when driving behind vehicles towing
low trailers when Adaptive Cruise Control or Pilot
Assist is activated.

DRIVER SUPPORT

331

High temperatures

If the temperature in the passenger compartment
is very high, the camera/radar sensor will switch
off temporarily for approx. 15 minutes after the
engine is started to protect its electronic compo-
nents. When the temperature has cooled suffi-
ciently, the camera/radar sensor will automati-
cally restart.

Damaged windshield

If there are cracks, scratches or stone chips
on the windshield in front of any of the cam-
era and radar unit "windows" and this covers
an area of about 0.5 × 3.0 mm
(0.02 × 0.12 in.) or more, contact a workshop
to have the windshield replaced – an author-
ized Volvo workshop is recommended.

Failure to take action could result in reduced
performance for the driver support systems
that use the camera and radar unit.

It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.

To avoid the risk of loss of function, malfunc-
tion or reduced function of the driver support
systems that use the radar unit, the following
also apply:

•

Volvo advises against repairing cracks,
scratches or stone chips in the area in
front of the camera and radar unit – the
entire windshield should instead be
replaced.

•

Before replacing the windshield, contact
an authorized Volvo workshop to verify
that the right windshield has been
ordered and installed.

•

The same type of windshield wipers or
wipers approved by Volvo should be used
for replacement.

If the windshield is replaced, the camera and
radar unit must be recalibrated by a workshop
to help ensure proper functioning of all of the
vehicle's camera and radar-based systems –
an authorized Volvo workshop is recom-
mended.

Camera limitations

The camera used by several of the driver support
functions has certain limitations, which also
affect the functions using the camera.

Reduced visibility

The camera has the same limitations as the
human eye. In other words, its “vision" is impaired
by adverse weather conditions such as heavy
snowfall/rain, dense fog, swirling dust/snow, etc.
These conditions may reduce the function of sys-
tems that depend on the camera or cause these
systems to temporarily stop functioning.

Strong sunlight, reflections from the road surface,
ice or snow covering the road, a dirty road sur-
face, or unclear lane marker lines may drastically
reduce the camera’s ability to detect the side of a
lane, a pedestrian, a cyclist, a large animal or
another vehicle.

Obstructed camera

The area marked in the illustration must be kept free of
decals, objects, solar film, etc.

The camera is located on the upper interior sec-
tion of the windshield along with the radar sen-
sor.

Do not place, affix or mount anything on the
inside or outside of the windshield, or in front
of or around the camera and radar unit – this
could disrupt camera and radar-based func-
tions.

City Safety™

City Safety can alert the driver with light, sound
and pulsations in the brake pedal to help the
driver detect pedestrians, cyclists, large animals
and vehicles that appear suddenly – the vehicle
will then attempt to automatically brake if the
driver does not act within a reasonable amount
of time.

Location of the camera and radar sensor

City Safety can help prevent a collision or lower
the vehicle's speed at the point of impact.

City Safety is an aid intended to assist the driver
if a collision with a pedestrian, large animal,
cyclist or vehicle is imminent.

City Safety can help the driver avoid a collision
when e.g. driving in stop-and-go traffic, when

changes in the traffic ahead and driver distraction
could lead to an incident.

The function assists the driver by automatically
applying the brakes if there is an imminent risk of
a collision and the driver does not react in time by
braking and/or steering away.

City Safety activates a brief, forceful braking in an
attempt to stop your vehicle immediately behind
the vehicle or object ahead.

City Safety is activated in situations in which the
driver should have applied the brakes much ear-
lier, which means that the system will not be able
to assist the driver in all situations.

City Safety is designed to be activated as late as
possible to help avoid unnecessary intervention.

Normally, the occupants of the vehicle will not be
aware of City Safety except when the system
intervenes when a collision is imminent.

Note: This illustration is general and details may vary depending on model.

WARNING

•

The City Safety function is supplementary
driver support intended to help improve
driving safety – it cannot handle all situa-
tions in all traffic, weather and road condi-
tions.

•

The City Safety auto-brake function can
prevent a collision or reduce collision
speed, but to ensure full brake perform-
ance the driver should always depress the
brake pedal – even when the car auto-
brakes.

•

The warning and steering assistance are
only activated if there is a high risk of col-
lision – you must therefore never wait for
the collision warning or City Safety to
intervene.

•

Warnings and brake interventions for
pedestrians and cyclists are disengaged
at vehicle speeds over 80 km/h
(50 mph).

•

City Safety does not activate auto-braking
intervention during heavy acceleration.

•

City Safety is not a substitute for the driv-
er's attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

•

The driver is advised to read all sections
in the Owner's Manual that relate to City
Safety to learn about factors such as its
limitations and what the driver should be
aware of before using the system (see
the list of links for all subsections).

City Safety parameters and sub-

functions

City Safety can help avoid a collision with a vehi-
cle, cyclist or large animal ahead by reducing the
vehicle's speed using its automatic braking func-
tion.

If the difference in speed is greater than the
speeds specified below, the City Safety auto-
brake function cannot prevent a collision, but it
can help mitigate its effects.

Vehicles

City Safety can help prevent a collision with a
vehicle ahead by reducing your vehicle's speed
by up to 60 km/h (37 mph).

Cyclists

City Safety can help prevent a collision with a
cyclist ahead by reducing your vehicle's speed by
up to 50 km/h (30 mph).

Pedestrians

City Safety can help prevent a collision with a
pedestrian ahead by reducing your vehicle's
speed by up to 45 km/h (28 mph).

DRIVER SUPPORT

* Option/accessory.

339

Large animals

If there is a risk of colliding with a large animal,
City Safety can help reduce your vehicle's speed
by up to 15 km/h (9 mph).

The braking function for large animals is primarily
intended to mitigate the force of a collision at
higher speeds. Braking is most effective at
speeds above 70 km/h (43 mph) and less effec-
tive at lower speeds.
