Volvo S60 (2018 year). Instruction - part 11

The driver's door must be closed and the driv-
er's seat belt must be fastened before ACC
can be put in active mode. If the driver's seat
belt is taken off or if the driver's door is
opened, ACC will return to standby mode.

Your vehicle can maintain the set time interval to
the vehicle ahead at any permissible speed,
including a complete stop.

In order to activate ACC at speeds below 18 mph
(30 km/h):

•

The vehicle ahead must be within a reasona-
ble distance (not farther away than approx.
100 ft/30 meters)

•

The lowest speed that can be selected is
18 mph (30 km/h), although ACC will also
help maintain the set time interval to the
vehicle ahead at lower speeds, including a
complete stop.

During short stops (less than approximately
3 seconds) in slow-moving traffic, your vehicle
will begin moving again automatically as soon as
the vehicle ahead begins to move.

If it takes more than 3 seconds for the vehicle
ahead to begin moving, ACC will be automatically
go into standby mode.

The driver will then have to reactivate ACC in one
of the following ways:

•

By pressing

•

By accelerating up to at least 3 mph
(4 km/h). ACC will then resume following the
vehicle ahead.

Your vehicle will then resume following the vehi-
cle ahead at the set time interval.

ACC can remain active and keep your vehicle
at a standstill for up to 4 minutes. After
4 minutes have elapsed, the parking brake
will be engaged and ACC will go into standby
mode.

To reactivate ACC, the driver must release the
parking brake (see Parking brake – general
information (p. 271)).

DRIVER SUPPORT

184

Automatic standby mode when ACC
changes target vehicles

If the vehicle ahead turns suddenly, there may be a sta-
tionary vehicle ahead

The following only applies at speeds below
approximately 18 mph (30 km/h):

If ACC changes target vehicles (the vehicle that
the radar sensor has detected) from a moving
vehicle to a stationary one, the system will apply
the brakes in your vehicle.

WARNING

At speeds above 18 mph (30 km/h), ACC
will not react to a stationary vehicle and apply
the brakes but will instead accelerate to the
previously set speed. The driver must actively
apply the brakes to stop the vehicle.

ACC disengages and goes into standby mode if:

•

Your vehicle's speed goes below 10 mph
(15 km/h) and ACC cannot determine if the
target object is a stationary vehicle or some

other type of object such as e.g., a speed
bump.

•

Your vehicle's speed goes below 10 mph
(15 km/h) and the vehicle ahead turns so
that ACC no longer has a target vehicle to
follow.

No automatic braking when at a
standstill

In certain situations, ACC will no longer apply the
brakes and go into standby mode while the vehi-
cle is not moving. This means that the driver will
have to apply the brakes.

This happens if:

•

The driver presses the brake pedal

•

The parking brake is activated

•

The gear selected is moved to P, N or R

•

The driver presses the

button to put ACC

in standby mode

The parking brake is applied
automatically

In certain situations, ACC will apply the parking
brake in order to continue keeping the vehicle at
a standstill.

This happens if:

•

The driver opens the door or takes off
his/her seat belt

•

The stability system is put in Sport mode
(see Stability system – operation (p. 167))

•

ACC has kept the vehicle at a standstill for
more than 2 minutes

•

The engine has been switched off

•

The brakes have overheated

Radar sensor

The radar sensor is designed to help detect cars
or larger vehicles driving in the same direction as
your vehicle, in the same lane.

The radar sensor and its limitations

In addition to being used by the Adaptive Cruise
Control (ACC), the radar sensor is also used by
Distance Alert (see Distance Alert – introduction
(p. 190)) and Collision Warning with Full Auto-
brake and Pedestrian Detection (see Collision
warning – introduction (p. 201)).

WARNING

•

If there is visible damage to the front
grille or you suspect that the radar sensor
may be damaged in any way, contact a
trained and qualified Volvo service techni-
cian as soon as possible. The radar sen-
sor may only function partially (or not at
all) if it is damaged or is not securely fas-
tened in place.

•

Accessories or other objects, such as
extra headlights, must not be installed in
front of the grille.

•

Modification of the radar sensor could
make its use illegal.

The radar sensor's capacity to detect vehicles
ahead is impeded:

•

if the radar sensor is obstructed and cannot
detect other vehicles, for example in heavy
rain, or if snow or other objects are obscuring
the radar sensor.

Keep the area in front of the radar sensor
clean.

•

if the speed of vehicles ahead is significantly
different from your own speed.

•

Adaptive Cruise Control –

limitations

The ACC cannot cover all driving situations and
traffic, weather and road conditions.

Situations where ACC may not function
optimally

WARNING

•

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

•

If ACC is not functioning properly, cruise
control will also be disabled.

DRIVER SUPPORT

186

Radar sensor's field of vision (shown in pink)

In certain situations, the radar sensor cannot
detect vehicles at close quarters, for example
a vehicle that suddenly enters the lane
between your vehicle and the target vehicle.
Small vehicles, such as motorcycles, or vehi-
cles not driving in the center of the lane may
remain undetected.
In curves, the radar sensor may detect the
wrong vehicle or lose sight of the target vehi-
cle.

WARNING

•

Adaptive Cruise Control cannot cover all
driving situations and traffic, weather and
road conditions. The "Function" section
provides information about limitations that
the driver must be aware of before using
this feature.

•

This system is designed to be a supple-
mentary driving aid. It is not, however,
intended to replace the driver's attention
and judgement. The driver is responsible
for maintaining a safe distance and speed
and must intervene if Adaptive Cruise
Control does not maintain a suitable
speed or suitable distance to the vehicle
ahead.

•

Maintenance of ACC components may
only be performed by a trained and quali-
fied Volvo technician.

WARNING

•

Adaptive Cruise Control is not a collision
avoidance system. The driver is always
responsible for applying the brakes if the
system does not detect another vehicle.

•

Adaptive Cruise Control does not react to
people or animals, or small vehicles such
as bicycles and motorcycles. It also does
not react to slow moving, parked or
approaching vehicles, or stationary
objects.

•

Do not use Adaptive Cruise Control in
demanding driving conditions such as city
driving or other heavy traffic situations, in
slippery conditions, when there is a great
deal of water or slush on the road, during
heavy rain or snow, in poor visibility, on
winding roads or on highway on- or off-
ramps.

Adaptive Cruise Control –

troubleshooting

If the message

Radar blocked See manual

displayed, this means that the radar signals from

the sensor have been obstructed and that a vehi-
cle ahead cannot be detected.

This, in turn, means that the functions of the
ACC, Distance Alert, and Collision Warning Sys-

tem with Auto-brake and Pedestrian Detection
will not function.

The table lists possible causes for this message
being displayed, and suitable actions.

Cause

Action

The surface of the radar in the grille is dirty or obstructed in some way.

Clean the radar surface, or remove the object causing the obstruction.

Heavy rain or snow is interfering with the radar signals.

No action possible. Heavy precipitation may affect the function of the radar.

Swirling water or snow from the surface of the road may interfere with
the radar signals.

No action possible. A very wet or snow-covered road surface may affect the
function of the radar.

The surface of the radar is clean but the message remains in the display.

Wait a short time. It may take several minutes for the radar to detect that it is no
longer obstructed.

Distance Alert – introduction

Distance Alert is part of Adaptive Cruise Control
and is a function that provides information about
the time interval to the vehicle ahead.

Introduction

Distance Alert is active at speeds above approxi-
mately 18 mph (30 km/h). Time interval informa-
tion is only given for a vehicle that is driving
ahead of your vehicle in the same direction. No
information is provided for vehicles driving toward
you, moving very slowly, or at a standstill.

Amber warning light

An amber warning light in the windshield glows
steadily if your vehicle is closer to the one ahead
than the set time interval.

Distance Alert – operation (p. 190)

Distance Alert only monitors distance to the
vehicle ahead while Adaptive Cruise Control is
in standby mode or off.

WARNING

Distance Alert only indicates the distance to
the vehicle ahead. It does not affect the
speed of your vehicle.

Five different time intervals can
be selected and are shown in
the display as 1–5 horizontal
bars. The greater the number of
bars, the longer the time inter-
val. One bar represents approx-
imately 1 second to the vehicle

ahead; 5 bars is approximately 3 seconds.

•

The higher your vehicle’s speed, the
greater the distance to the vehicle ahead,
measured in feet (meters), for a given
time interval.

•

The set time interval is also used by
Adaptive Cruise Control, see Adaptive
Cruise Control – setting speed (p. 179).

WARNING

Only use a time interval that is suitable in cur-
rent traffic conditions.

Distance Alert – limitations

Distance Alert is part of Adaptive Cruise Control
and is a function that provides information about
the time interval to the vehicle ahead.

Limitations

Distance Alert uses the same radar sensor used
by Adaptive Cruise Control and the Collision
Warning system. See Adaptive Cruise Control –
limitations (p. 185) for more information on the
radar sensor’s limitations.

Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the
warning symbol in the windshield difficult to
see.

WARNING

•

Bad weather or winding roads may affect
the radar sensor’s capacity to detect vehi-
cles ahead.

•

The size of the vehicle ahead, such as a
motorcycle, may also make it difficult to
detect. This may result in the warning
light illuminating at a shorter distance
than the one that has been set, or that
the light will not come on at all.

City Safety – introduction

City Safety

™

is a support system designed to

help the driver avoid low speed collisions when
driving in slow-moving, stop-and-go traffic.

City Safety

™ is not active if your vehicle’s speed

is below approximately 2 mph (4 km/h). This
means that City Safety

™ will not react if your

vehicle approaches another vehicle at very low
speed, for example, when parking.

The function is active at speeds up to approxi-
mately 30 mph (50 km/h) and assists the driver
by applying the brakes automatically, thereby
avoiding or helping to reduce the effects of a col-
lision.

City Safety

™ is designed to intervene as late as

possible to help avoid unnecessary activation.

City Safety

™ triggers brief, forceful braking if a

low-speed collision is imminent. However, the
system will not intervene in situations where the
driver actively steers the vehicle or applies the
brakes, even if a collision cannot be avoided. This
is done in order to always give the driver’s actions
highest priority.

City Safety

™ activates in situations where the

driver has not applied the brakes in time, which
means that the system cannot help the driver in
all situations.

City Safety

™ should not be used to alter the way

in which the driver operates the vehicle. The
driver should never rely solely on this system to
safely stop the vehicle.

Normally, the occupants of the vehicle will not be
aware of City Safety

™ except when the system

intervenes when a low-speed collision is immi-
nent.

If the vehicle is also equipped with the optional
Collision Warning with Full Auto-brake and
Pedestrian Detection system, the two systems
interact. For more information about the Collision
Warning with Auto-brake system, see Collision
warning – introduction (p. 201) .

WARNING

•

City Safety

™ is a supplemental aid to the

driver. It can never replace the driver’s
attention to traffic conditions or his/her
responsibility for operating the vehicle in
a safe manner.

•

City Safety

™ does not function in all driv-

ing situations or in all traffic, weather or
road conditions.

WARNING

•

City Safety

™ only reacts to vehicles trav-

eling in the same direction as your vehicle
and does not react to small vehicles or
motorcycles or to people or animals.

•

City Safety

™ is not activated when your

vehicle is backing up.

•

City Safety

™ functions at speeds up to

30 mph (50 km/h). This system can help
prevent a collision if the difference in
speed between your vehicle and the
vehicle ahead is less than 9 mph
(15 km/h). If the difference in speed is
greater, a collision cannot be avoided but
the speed at which the collision occurs
can be reduced. The driver must apply the
vehicle’s brakes for full braking effect.

•

City Safety

™ will not intervene in a

potential collision situation if the vehicle
is being driven actively. The driver is
always responsible for maintaining a safe
distance to a vehicle or object ahead.

City Safety – function

Function

Location of the laser sensor in the windshield

City Safety

™ monitors traffic ahead of you using

a laser sensor mounted in the upper section of
the windshield. If a collision is imminent, City
Safety

™ will automatically apply the brakes,

which may feel like hard braking.

If the difference in speed between your vehicle
and the vehicle ahead is more than approximately
9 mph (15 km/h), City Safety

™ alone cannot

prevent a collision from taking place. The driver
must apply the brakes to help avoid a collision or
reduce its effect.

When the function activates and applies the
brakes, a message will appear in the information

display to indicate that the system is/has been
active.

•

When City Safety

™ applies the brakes,

the brake lights will illuminate.

•

In cases where City Safety

™ has stopped

the vehicle, the system will then release
the brakes. The driver must apply the
brakes to keep the vehicle at a standstill.

City Safety – operation

Using City Safety

™

The City Safety

™ function is activated auto-

matically each time the engine has been
switched off and restarted.

On and Off

In certain situations, it may be desirable to switch
City Safety

™ off, such as when driving in close

quarters where leaves, branches, etc. may
obscure the hood and windshield.

When the engine is running, City Safety

™ can be

switched off as follows:

Press My Car in the center console control panel
and go to

Settings

Limitations

WARNING

The laser sensor has certain limitations and
its function may be reduced (or it may not
function at all) in conditions such as heavy
rain or snowfall, or by dense fog or thick,
blowing dust or snow. Condensation, dirt, ice
or snow on the windshield may also interfere
with the sensor’s function.

The sensor used by City Safety

™ is designed to

detect cars and other larger motor vehicles
ahead of your vehicle in both daylight and dark-
ness.

Objects such as warning flags hanging from long
objects on the roof or accessories such as auxili-
ary lights or protective arches on the front of the
vehicle that are higher than the hood may also
impede the sensor’s function.

Braking distance to the vehicle ahead increases
on slippery road surfaces, which may reduce City
Safety’s capacity to avoid a collision. In situations
like this, the stability system (see Stability system
– introduction (p. 166)) will help provide the best
possible braking capacity and stability.

City Safety

™ emits a laser beam and measures

the way in which the light is reflected. Therefore,
vehicles or objects with low-reflective surfaces

may not be detected. Normally, the license plate
and taillight reflectors give the rear section of a
vehicle ahead sufficient reflective surfaces to be
detected.

•

Keep the windshield in front of the laser
sensor free of ice, snow, dirt, etc., see City
Safety – function (p. 195).

•

Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sensor.
Keep the hood free of ice and snow.

•

Do not mount or in any way attach any-
thing on the windshield that could
obstruct the laser sensor.

appears in the

information display, this indicates that the City
Safety

™ laser sensor is obstructed in some way

and cannot detect vehicles ahead of you, which
means that the system is not functioning.

However, this message will not be displayed in all
situations in which the sensor is obstructed. For
this reason, the driver must ensure that the area
of the windshield in front of the sensor is always
kept clean.

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 sensor is
dirty or covered by ice or
snow.

Clean the wind-
shield or remove
the ice/snow.

The laser sensor's field of
view is obstructed.

Remove the
obstruction.

If a crack, scratch or stone chip should occur
in the section of the windshield in front the
laser sensor, contact a trained and qualified
Volvo service technician to repair or replace
the windshield (see the illustration showing
the location of the sensor in City Safety –
function (p. 195)). Failing to do so may result
in reduced City Safety

™ functionality.

To help prevent limited or reduced functional-
ity, please also observe the following:

•

Volvo recommends that cracks, scratches
or stone chips on the windshield in front
of the laser sensor should not be
repaired; in such cases, the entire wind-
shield should be replaced.

•

Before the windshield is replaced, con-
tact a Volvo retailer to ensure that the
correct windshield is ordered and instal-
led. If the wrong type of windshield is
used, this may cause City Safety

™ to

function improperly or not at all. Volvo
recommends the use of only Genuine
Volvo Replacement Windshields.

•

When replacing windshield wipers, use
the same type or ones approved by Volvo.
