Limitations of Distance Warning

The Distance Warning function

may have limi-

tations in certain situations.

WARNING

•

The Distance Warning function is supple-
mentary driver support intended to facili-
tate driving and make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.

•

The vehicle's size may affect the ability to
detect, e.g. motorcycles, which could
mean that the warning lamp illuminates at
a shorter time window than set or that the
warning is temporarily absent.

•

Extremely high speeds can cause the
lamp to illuminate at a shorter time win-
dow than that set due to limitations in
radar unit range.

•

Distance Warning is not a substitute for
the driver's attention and judgement. The
driver is always responsible for ensuring
the car 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.

NOTE

The function uses the car's radar unit, which
has some general limitations, see the section
"Limitations for radar unit".

Adaptive cruise control

The adaptive cruise control (ACC

) helps the

driver to maintain an even speed combined with
a pre-selected time interval to the vehicle ahead.

An adaptive cruise control provides a more relax-
ing driving experience on long journeys on motor-
ways and long straight main roads in smooth traf-
fic flows.

The camera and radar unit measures the distance to the
vehicle ahead

The driver selects the desired speed and a time
interval to the vehicle ahead. If the camera and
radar unit detects a slower vehicle in front of the
car, the speed is adapted automatically via the
preset time interval to the vehicle. When the road

is clear again the car returns to the selected
speed.

WARNING

•

The adaptive cruise control function is
supplementary driver support intended to
facilitate driving and 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 that relate to this
function 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 at the end of this article).

•

The adaptive cruise control is not a sub-
stitute for the driver's attention and
judgement. The driver is always responsi-
ble for ensuring the car is driven in a safe
manner, at the appropriate speed, with an
appropriate distance to other vehicles,
and in accordance with current traffic
rules and regulations.

Adaptive cruise control regulates the speed with
acceleration and braking. It is normal for the
brakes to emit a low sound when they are being
used to adjust the speed.

The adaptive cruise control aims to control the
speed in a smooth way. In situations that demand
sudden braking the driver must brake himself/

herself. This applies in case of large speed differ-
ences or if the vehicle in front brakes suddenly.
Due to the limitations of the radar unit, braking
may come unexpectedly or not at all.

The adaptive cruise control aims to follow the
vehicle ahead in the same lane at a time interval
set by the driver. If the radar unit cannot see any
vehicle in front then the car will instead maintain
the speed set and stored by the driver. This also
takes place if the speed of the vehicle ahead
increases and exceeds the stored speed.

The following applies for cars with automatic
gearbox:

•

Adaptive cruise control can follow another
vehicle at speed from 0 km/h up to
200 km/h (125 mph).

The following applies for cars with manual gear-
box:

•

The Adaptive cruise control can follow
another vehicle at speeds from 30 km/h
(20 mph) up to 200 km/h (125 mph).

WARNING

•

Adaptive cruise control is not a collision
avoidance system. The driver is always
responsible and must intervene if the sys-
tem does not detect a vehicle ahead.

•

The adaptive cruise control does not
brake for humans or animals, and not for
small vehicles such as bicycles and
motorcycles. Nor for low trailers, oncom-
ing, slow or stationary vehicles and
objects.

•

Do not use the adaptive cruise control in
demanding situations, such as in city traf-
fic, at junctions, on slippery surfaces, with
a lot of water or slush on the road, in
heavy rain/snow, in poor visibility, on
winding roads or on slip roads.

IMPORTANT

Maintenance of adaptive cruise control com-
ponents must only be performed at a work-
shop - an authorised Volvo workshop is rec-
ommended.

Collision risk warning

Warning light for collision warning on the windscreen

Adaptive Cruise Control uses approx. 40% of the
capacity of the foot brake. If the car needs to be
braked more heavily than the adaptive cruise
control is capable of and the driver does not
brake, the warning lamp and acoustic warning are
activated to alert the driver that immediate inter-
vention is required.

NOTE

Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the vis-
ual warning signal in the windscreen difficult
to recognise.

WARNING

The adaptive cruise control only warns of

vehicles which its radar unit has detected -

hence a warning may not be given, or it may

be given with a certain delay.

•

Never wait for a warning. Apply the
brakes when the situation requires.

•

The speed set after the last button press is
stored in the memory.

If the driver increases the car’s speed using the
accelerator pedal before pressing the steering
wheel button

, the speed stored will be the

car’s speed when the button is depressed, provi-
ded the driver’s foot is on the accelerator pedal at
the moment when the button is depressed.

A temporary increase in speed with the accelera-
tor pedal, e.g. during overtaking, does not affect
the setting - the car returns to the last stored
speed when the accelerator pedal is released.

Automatic gearbox

Adaptive cruise control can follow another vehicle
at speeds from 0 km/h up to 200 km/h
(125 mph).

Note that the lowest programmable speed for the
adaptive cruise control is 30 km/h (20 mph) -
even though it is capable of following another
vehicle down to 0 km/h, a speed lower than
30 km/h (20 mph) cannot be selected/stored.

The maximum speed selectable is 200 km/h
(125 mph).

Manual gearbox

The Adaptive cruise control can follow another
vehicle at speeds from 30 km/h (20 mph) up to
200 km/h (125 mph).

The lowest programmable speed for the adaptive
cruise control is 30 km/h (20 mph) - the maxi-
mum speed is 200 km/h (125 mph).

The Adaptive Cruise Control (ACC

) can be

set to different time intervals.

Different time intervals to the
vehicle in front can be selected
and shown in the driver display
as 1-5 horizontal lines - the
more lines the longer the time
interval. One line represents
about 1 second to the vehicle

in front, 5 lines represents about 3 seconds.

The same symbol is also shown when the Dis-
tance Warning function is activated.

NOTE

When the symbol in the driver display shows
two cars, ACC is following the vehicle in front
at a pre-set time interval.

When only one car is shown, there is no vehi-
cle within a reasonable distance ahead.

Distance indicator

–

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

rent time interval.

The adaptive cruise control allows the time inter-
val to vary significantly in certain situations in
order to allow the car to follow the vehicle in front
smoothly and comfortably. At low speed, when
the distances are short, the adaptive cruise con-
trol increases the time interval slightly.

NOTE

•

The higher the speed the longer the cal-
culated distance in metres for a given
time interval.

•

Only use the time intervals permitted by
local traffic regulations.

•

If the adaptive cruise control does not
seem to respond with a speed increase
when activated, it may be because the
time window to the vehicle ahead is
shorter than the set time window.

WARNING

•

Only use a time window that suits the
current traffic conditions.

•

The driver should be aware that short
time windows limit the amount of time
available to react and take action if an
unexpected traffic situation arises.

Select how ACC shall maintain the
distance

* to the vehicle ahead

The driver can select different driving styles for
how the Adaptive cruise control should maintain
the preset time interval to the vehicle ahead.
Selection is made via the drive mode control
DRIVE MODE.

Select one of the following alternatives:

•

Eco

- ACC focuses on optimal fuel economy,

which means longer time interval to the vehi-
cle ahead.

•

Comfort

- ACC focuses on following the set

time interval to the vehicle ahead as
smoothly as possible.

•

Dynamic

- ACC focuses on following the set

time interval to the vehicle ahead more
closely, which in certain cases may mean
heavier acceleration and braking.

Standby mode on driver intervention

The Adaptive cruise control is temporarily deacti-
vated and set in standby mode if:

•

the foot brake is used

•

the gear selector is moved to N position.

•

the driver maintains a speed higher than the
stored speed for longer than 1 minute.

•

the clutch pedal is depressed for approx. 1
minute - applies to cars with manual gearbox.

A temporary increase in speed with the accelera-
tor pedal, e.g. during overtaking, does not affect
the setting - the car returns to the last stored
speed when the accelerator pedal is released.

Automatic standby mode

The adaptive cruise control is dependent on
other systems, e.g. Electronic Stability Control
ESC

. If any of the other systems stops working,

the adaptive cruise control is deactivated auto-
matically.

WARNING

With automatic standby mode, the driver is

warned via an acoustic signal and a message

on the driver display.

•

The driver must then regulate the car's
speed, apply the brakes as needed and
maintain a safe distance to other vehicles.

Automatic standby mode may occur if:

•

the speed is below 5 km/h (3 mph) and ACC
is uncertain whether the vehicle ahead is a
stationary vehicle or an object, such as a
speed bump.

•

the speed is below 5 km/h (3 mph) and the
vehicle ahead turns off so that ACC no
longer has a vehicle to follow.

•

speed is reduced to below 30 km/h
(20 mph) - only applies to cars with manual
gearbox.

•

the driver opens the door

•

the driver takes off the seatbelt

•

engine speed is too low/high

•

one or more wheels lose traction

•

brake temperature is high

•

the parking brake is applied

•

the camera and radar unit is covered by e.g.
snow or heavy rainfall (camera lens/radio
waves are blocked).

Reactivating adaptive cruise control
from standby mode

NOTE: The illustration is schematic - details may vary

depending on car model.

To reactivate ACC from standby mode:

–

Press the steering wheel button

(1).

> The speed is then set to the most recently

stored speed.

WARNING

A significant increase in speed may follow
when the speed is resumed with the

steering wheel button.

Overtaking assistance with adaptive

cruise control

* or Pilot Assist*

Adaptive cruise control (ACC

) or Pilot Assist

can assist the driver when overtaking other vehi-
cles.

How overtaking assistance works

When ACC or Pilot Assist is following another
vehicle and the driver indicates the intention to
overtake by activating the direction indicator

adaptive cruise control or Pilot Assist helps by
accelerating the car towards the vehicle ahead
before the car reaches the overtaking lane.

The function then delays reducing speed in order
to avoid premature braking when the driver’s car
is approaching a slower vehicle.

The function remains active until the driver’s vehi-
cle has cleared the overtaken vehicle.

WARNING

Be aware that this function can be activated

in more situations than during overtaking, e.g.

when a direction indicator is used to indicate

a change of lane or exit to another road – the

car will then accelerate briefly.

Continuation for Overtaking Assistance

The following conditions must exist for Overtak-
ing Assistance to be activated:

•

there must be a vehicle in front (the “target
vehicle”)

•

your car's current speed is at least 70 km/h
(43 mph)

•

the stored speed for ACC or Pilot Assist
must be high enough for overtaking to take
place safely.

Starting Overtaking Assistance

To start the Overtaking Assistance:

–

Activate the direction indicator.

Use the left direction indicator in a car with
the steering wheel on the left, or the right
direction indicator in a car with the steering
wheel on the right.
> Overtaking Assistance is started.

Adaptive Cruise Control

On left flash only in left-hand-drive car, or right flash in right-hand-drive car.

Limitations for Overtaking Assistance

WARNING

When using the Overtaking Assistance Sys-

tem, the driver should be aware that there

may be undesired acceleration if the condi-

tions suddenly change.
Some situations should therefore be avoided,

such as if:

•

the car is approaching an exit for turn-of
that is in the same direction as overtaking
would normally occur.

•

the vehicle ahead slows down before the
driver's car has crossed over into the
overtaking lane

•

the traffic in the overtaking lane slows
down

•

a right-hand drive car is driven in a county
with left-hand traffic (or vice versa).

Situations of this kind can be avoided by tempo-
rarily setting ACC or Pilot Assist in standby mode.

Change of target and automatic

braking with the Adaptive Cruise

Control

In combination with automatic gearbox, the
adaptive cruise control (ACC

) has functionality

for change of target and braking at certain
speeds.

Change of target

If the target vehicle in front suddenly turns then there

may be stationary traffic in front.

When adaptive cruise control is following another
vehicle at speeds below 30 km/h (20 mph) and
changes target from a moving to a stationary
vehicle, the adaptive cruise control will slow down
for the stationary vehicle.

WARNING

When the adaptive cruise control is following

another vehicle at speeds in excess of

approx. 30 km/h (20 mph) and the target is

changed from a moving vehicle to a stationary

vehicle, the adaptive cruise control will ignore

the stationary vehicle and instead accelerate

to the stored speed.

•

The driver must then intervene him/
herself and brake.

Automatic standby mode with change of
target

The adaptive cruise control is disengaged and set
in standby mode:

•

when the speed is below 5 km/h (3 mph)
and the adaptive cruise control is uncertain
whether the target object is a stationary vehi-
cle or some other object, such as a speed
bump.

•

when the speed is below 5 km/h (3 mph)
and the vehicle ahead turns off so the adap-
tive cruise control no longer has a vehicle to
follow.

Automatic braking

For shorter stops in connection with inching in
slow traffic or at traffic lights driving is automati-
cally resumed if the stops do not exceed about
3 seconds - if it takes longer before the car in

front starts moving again then the adaptive cruise
control is set in standby mode with automatic
braking.

–

The Adaptive Cruise Control is reactivated in
one of the following ways:

•

Press the steering wheel button

•

Depress the accelerator pedal.

> The Adaptive Cruise Control resumes fol-

lowing the vehicle ahead if it starts mov-
ing forward within 6 seconds.

NOTE

ACC can keep the car stationary for a maxi-
mum of 5 minutes. After this the parking
brake is applied and adaptive cruise control is
disengaged.

The parking brake must be released before
the adaptive cruise control can be reactivated.

Cessation of automatic braking

In some situations, automatic braking ceases on
reaching 0 km/h and Adaptive Cruise Control is
set in standby mode. This means that the brakes
are released and the car may start to roll - the
driver must therefore intervene and brake the car
himself/herself to keep it stationary.

This may take place in the following situations:

•

the driver puts his/her foot on the brake
pedal

•

the parking brake is applied

•

the gear selector is moved to P, N, or R posi-
tion

•

the driver sets the adaptive cruise control in
the standby mode.

Automatic activation of parking brake

In certain situations the parking brake is applied
to keep the car stationary.

This takes place if the adaptive cruise control is
holding the car stationary with the foot brake and:

•

the driver opens the door or takes off his/her
seatbelt

•

ACC has kept the car stationary for more
than approx. 5 minutes

•

the brakes have overheated

•

the engine is switched off.

Limitations of the adaptive cruise

control

Adaptive cruise control (ACC

) may have limita-

tions in certain situations.

Steep roads and/or heavy load

Bear in mind that the adaptive cruise control is
primarily intended for use when driving on level
road surfaces. The function may have difficulty in
keeping the correct distance from the vehicle
ahead when driving on steep downhill slopes - in
which case, be extra attentive and ready to brake.

•

Do not use adaptive cruise control if the car
has a heavy load or a trailer is connected to
the car.

Miscellaneous

•

Drive mode

Off Road

cannot be selected

when the adaptive cruise control is activated.

NOTE

The function uses the car's camera unit,
which has some general limitations, see the
"Limitations for camera unit" section.

NOTE

The function uses the car's radar unit, which
has some general limitations, see the section
"Limitations for radar unit".

)

the driver can change between Cruise Control
(CC

) and ACC.

A symbol in the driver display shows which cruise
control is active:

ACC

Cruise control

Adaptive cruise control

WHITE symbol: Function active, GREY symbol: Standby mode

Changing from ACC to CC

Proceed as follows:

1. Set adaptive cruise control to standby mode

using steering wheel button

2. Press the

Cruise control

button in the cen-

tre display's function view - the button's indi-
cator changes colour from GREY to GREEN.
> The symbol in the driver display changes

from

ACC to

CC. Adap-

tive Cruise Control is now switched off
and Cruise Control is set to standby
mode.

3. Press the steering wheel button

> Cruise control starts and stores the cur-

rent speed.

WARNING

Switching from ACC to CC means that the

car:

•

no longer maintains a preset time interval
to the vehicle ahead.

•

only follows the stored speed, and the
driver must therefore apply the brakes
