Volvo XC60 Twin Engine (2019 year). Instruction - part 18

Automatic braking with Adaptive

Cruise Control

The Adaptive cruise control (ACC

) has a spe-

cial brake function in slow traffic and while sta-
tionary.

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,
Adaptive Cruise Control will go into standby
mode and the Auto-hold brake function will acti-
vate.

–

Adaptive Cruise Control can be reactivated in
one of the following ways:

•

Pressing the

button on the steering

wheel keypad.

•

Pressing the accelerator pedal.

> Adaptive Cruise Control will resume fol-

lowing the vehicle ahead if it begins to
move within approx. 6 seconds.

ACC can keep the vehicle stationary for no
more than 5 minutes – after that time the
parking brake is applied and Adaptive Cruise
Control is deactivated.

The parking brake must be released before
Adaptive Cruise Control 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 Adaptive
Cruise Control 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 sta-
tionary.

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 Adaptive Cruise Control 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 Adaptive Cruise Control is keeping
the vehicle stationary using the brakes and:

•

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

•

ACC has kept the vehicle at a standstill for
more than approx. 5 minutes

•

the brakes overheat

•

the driver switches off the engine manually.

Adaptive Cruise Control limitations

Adaptive Cruise Control (ACC

) may have lim-

ited functionality in certain situations.

Steep roads and/or heavy loads

Adaptive Cruise Control is primarily intended to
be driven on flat roads. The function may not be
able to maintain 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 Adaptive Cruise Control if the
vehicle is carrying a heavy load or towing a
trailer.

Other limitations

•

The

Off Road

drive mode cannot be

selected if Adaptive Cruise Control is acti-
vated.

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".

Pilot Assist

Pilot Assist helps the driver keep the vehicle in
the current traffic lane by providing steering
assistance and maintaining an even speed and a
set time interval to the vehicle ahead.

How Pilot Assist works

The Pilot Assist function is primarily intended for
use on highways and other major roads where it
can help provide a more comfortable and relaxing
driving experience.

The camera/radar sensor monitors the distance to the
vehicle ahead and detects lane markings

Camera and radar sensor

Distance monitor

Lane marker line monitors

The driver sets the desired speed and distance to
the vehicle ahead. Pilot Assist monitors the dis-
tance to the vehicle ahead and the traffic lane's
side markers using the camera and radar sensor.
The system maintains the set time interval to the
vehicle ahead by automatically adjusting your
vehicle's speed and keeps your vehicle in its lane
by providing steering assistance.

Pilot Assist's steering assistance is based on
monitoring the direction of the vehicle ahead and
the traffic lane's side marker lines. The driver can
override Pilot Assist's steering recommendations
at any time and steer in another direction, e.g. to
change lanes or avoid obstacles on the road.

If the camera/radar sensor cannot detect the
lane's side marker lines or if Pilot Assist is unable
for some other reason to clearly interpret the
lane, Pilot Assist will temporarily deactivate steer-
ing assistance until it can once again interpret
the lane markings. However, the speed and dis-
tance warnings will remain active.

WARNING

Pilot Assist is deactivated automatically and

resumes working without prior notice.

The color of the steering wheel
symbol indicates the current
status of steering assistance:

• GREEN indicates that steer-
ing assistance is active

• GRAY (as shown in illustra-

tion) indicates that steering assistance is deacti-
vated.

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

DRIVER SUPPORT

311

WARNING

•

The Pilot Assist function is supplementary
driver support intended to facilitate driv-
ing and help make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.

•

The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).

•

Pilot Assist should only be used if there
are clear lane lines painted on each side
of the lane. All other use will increase the
risk of contact with nearby obstacles that
cannot be detected by the functions.

•

Pilot Assist 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
proper position within the lane, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

Pilot Assist and collision warning (p. 313)

Depending on market, this function may be
either Standard or Optional.

Pilot Assist regulates speed by accelerating and
braking. It is normal for the brakes to emit a slight
sound when they are being used to adjust speed.

Pilot Assist attempts to smoothly regulate speed.
The driver must apply the brakes in situations
requiring immediate braking. For example, when
there are great differences in speed between
vehicles or if the vehicle ahead brakes suddenly.
Due to limitations in the camera and radar sen-
sor, braking may occur unexpectedly or not at all.

Pilot Assist is designed to follow a vehicle ahead
in the same lane and maintain a time interval to
that vehicle set by the driver. If the radar sensor
does not detect a vehicle ahead, it will instead
maintain the speed set by the driver. This will also
happen if the speed of the vehicle ahead
exceeds the set speed for your vehicle.

•

Pilot Assist can follow another vehicle at
speeds from a standstill up to 200 km/h
(125 mph).

•

Pilot Assist can provide steering assistance
from near-stationary speeds up to 140 km/h
(87 mph).

WARNING

•

Pilot Assist is not a collision avoidance
system. The driver must intervene if the
system fails to detect a vehicle ahead.

•

Pilot Assist does not brake for people,
animals, objects, small vehicles (e.g.
cycles and motorcycles), low trailers as
well as oncoming, slow or stationary vehi-
cles.

•

Do not use Pilot Assist in demanding sit-
uations, such as in city traffic, at intersec-
tions, on slippery surfaces, with a lot of
water or slush on the road, in heavy rain/
snow, in poor visibility, on winding roads,
on highway on- or off-ramps, or with a
trailer connected to the vehicle.

CAUTION

Maintenance of the integrated components in
Pilot Assist may only be performed by a work-
shop – an authorized Volvo workshop is rec-
ommended.

In curves and forks in the road

Pilot Assist is designed to interact with the driver.
The driver should never wait for steering assis-
tance from Pilot Assist, but instead should always
be ready to increase his or her own steering
efforts, particularly in curves.

DRIVER SUPPORT

312

•

When the vehicle is approaching an off-ramp
or a fork in the road, the driver should steer
toward the desired lane to indicate to Pilot
Assist the desired direction of travel.

Pilot Assist strives to keep the vehicle
in the center of the lane

When Pilot Assist provides steering assistance, it
strives to position the vehicle in the center of the
lane between the lane markings. For the smooth-
est driving experience possible, the driver should
permit the vehicle to find the optimal positioning.
The driver should check that the vehicle is posi-
tioned safely in the lane and can always adjust
the vehicle's position by applying more force to
the steering wheel.

•

If Pilot Assist does not position the vehicle
appropriately in the lane, the driver should
turn off Pilot Assist or switch to Adaptive
Cruise Control.

The higher speed is the set
speed for your vehicle and the
lower speed is the speed of the
vehicle ahead (target vehicle).

Hands on the steering wheel

Pilot Assist only functions if the driver's hands
are on the steering wheel.

If Pilot Assist detects that the
driver's hands are not on the
steering wheel, a symbol and
text message will appear to
instruct the driver to actively
steer the vehicle.

If the driver's hands are still detected on the
steering wheel after a few seconds have passed,
the instructions to actively steer the vehicle will
be repeated, accompanied by an audible signal.

: Reduces the set speed

Set speed

–

Change a set speed by pressing the

(1)

(2) buttons briefly or by pressing and

holding them:

•

Press briefly: Press briefly: each press
changes the speed in +/- 5 mph
(+/- 5 km/h) increments.

•

Press and hold: release the button when
the set speed indicator (3) has moved to
the desired speed.

•

The most recently set speed will be stored.

If speed is increased by depressing the accelera-
tor pedal while pressing the

(1) button on

the steering wheel, the vehicle's speed when the
button is pressed will be stored as the set speed.

Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.

Automatic transmission

Pilot Assist can follow another vehicle at speeds
from a standstill up to 200 km/h (125 mph).

The lowest speed that can be set for Pilot Assist
is 30 km/h (20 mph). When following another
vehicle, ACC can monitor that vehicle's speed
and slow your own vehicle down to a standstill,
but it is not possible to set speeds lower than
30 km/h (20 mph).

The highest possible speed that can be set is
200 km/h (125 mph).

Setting a time interval for Pilot

Assist

Pilot Assist can be set to different time intervals.

Different time intervals to the
vehicle ahead can be selected
and are shown in the instru-
ment panel as 1–5 horizontal
bars. The more bars, the longer
the time interval. One bar rep-
resents an interval of

approx. 1 second to the vehicle ahead. 5 bars
represents approx. 3 seconds.

When the symbol in the instrument panel
shows a vehicle and a steering wheel, Pilot
Assist follows a vehicle ahead at a preset
time interval.

When only a steering wheel is shown, there is
no vehicle ahead within a reasonable dis-
tance.

Controls for setting a time interval

Reduce the time interval

Increase the time interval

Distance indicator

–

Press the (1) or (2) button to decrease or
increase the time interval.
> The distance indicator (3) shows the cur-

rent time interval.

In order to follow the vehicle ahead as smoothly
as possible, Pilot Assist allows the time interval to
vary considerably in certain situations. For exam-
ple, at low speeds and short distances to the
vehicle ahead, Pilot Assist increases the time
interval slightly.

•

The greater the vehicles' speed, the
greater the distance between them for a
set time interval.

•

Only use the time intervals permitted by
local traffic regulations.

•

If Pilot Assist does not seem to respond
with a speed increase when activated, it
may be because the time interval to the
vehicle ahead is shorter than the set time
interval.

WARNING

•

Only use a time interval suitable for the
current traffic conditions.

•

The driver should be aware that short
time intervals give them limited time to
react and act to any unforeseen traffic
situation.

Setting how Pilot Assist should
maintain distance* to the vehicle ahead

The driver can choose different drive modes to
determine how Pilot Assist should maintain a
time interval to the vehicle ahead. Settings are
made using the DRIVE MODE controls.

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

DRIVER SUPPORT

318

Select one of the following:

•

Eco

- Pilot Assist will focus on providing

optimal fuel economy, which will increase the
time interval to the vehicle ahead.

•

Comfort

- Pilot Assist will focus on following

the set time interval to the vehicle ahead as
smoothly as possible.

•

Dynamic

- Pilot Assist will focus on follow-

ing the set time interval to the vehicle ahead
more exactly, which could mean faster accel-
eration and heavier braking.

vated. When the turn signal is switched off, steer-
ing assistance will be automatically reactivated if
the traffic lane's side markings can still be
detected.

Automatic standby mode

Pilot Assist is dependent on other systems, such
as Electronic Stability Control (ESC

). If any of

these other systems stops working, Pilot Assist
will automatically switch off.

WARNING

With automatic standby mode, the driver is

warned by an acoustic signal and a message

on the instrument panel.

•

The driver must then regulate vehicle
speed, apply the brakes if necessary, and
maintain a safe distance to other vehicles.

Adaptive Cruise Control may go into standby
mode if, e.g.:

•

the driver opens the door.

•

the brake temperature is high.

•

the driver's hands are not on the steering
wheel.

•

the parking brake is applied.

•

the engine speed (rpm) is too low/high.

•

the driver unbuckles the seat belt.

•

one or more of the wheels lose traction.

•

the camera/radar sensor is covered by snow
or heavy rain (the camera lens/radar waves
are blocked)

•

your vehicle's speed goes below 5 km/h
(3 mph) and Pilot Assist cannot determine if
the vehicle ahead is stationary or if it is
another object, e.g. a speed bump.

•

your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
Pilot Assist no longer has a vehicle to follow.

Passing assistance with Pilot Assist

Pilot Assist can assist the driver when passing
other vehicles.

How passing assistance works

When Pilot Assist is following another vehicle
and you indicate that you intend to pass that
vehicle by using the turn signal

, Pilot Assist will

begin accelerating toward the vehicle ahead
before your vehicle has moved into the passing
lane.

The function will then delay a speed reduction to
avoid early braking as your vehicle approaches a
slower-moving vehicle.

The function remains active until your vehicle has
passed the other vehicle.

WARNING

Please note that this function can be acti-

vated in more situations than just passing

another vehicle, such as when a direction indi-

cator is used to indicate a lane change or

before exiting to another road – the vehicle

will then briefly accelerate.
