Adaptive cruise control - ACC*

The adaptive cruise control (ACC – Adaptive

Cruise Control) helps the driver to maintain an

even speed combined with a pre-selected

time interval to the vehicle ahead.

The adaptive cruise control provides a more

relaxing driving experience on long journeys

on motorways and long straight main roads in

smooth traffic flows.
The driver sets the desired speed (p. 209)

and time interval (p. 210) to the car in front.

When the radar detector detects a slower

vehicle in front of the car, the speed is auto-

matically adapted to that. When the road is

clear again the car returns to the selected

speed.
If the adaptive cruise control is switched off

or set to standby mode (p. 211) and the car

comes too close to a vehicle in front, then the

driver is warned instead by the Distance

Warning (p. 220) function about the short

distance.

Option/accessory, for more information, see Introduction.

WARNING

The driver must always be observant with

regard to the traffic conditions and inter-

vene when the adaptive cruise control is

not maintaining a suitable speed or suita-

ble distance.
The adaptive cruise control cannot handle

all traffic, weather and road conditions.
Read all the sections about the adaptive

cruise control in the owner's manual in

order to learn about its limitations, of

which the driver should be aware before it

is used.
The driver always bears responsibility for

maintaining the correct distance and

speed, even when the adaptive cruise con-

trol is being used.

IMPORTANT

Maintenance of adaptive cruise control

components must only be performed at a

workshop - an authorised Volvo workshop

is recommended.
For a limited time after the service, the

ACC function can have a somewhat lim-

ited range. The system is calibrated whilst

driving and full function returns automati-

cally.

Automatic gearbox
Cars with automatic gearbox have enhanced

functionality with the adaptive cruise control's

Queue assistance (p. 212) function.

Function overview

Warning lamp - braking by driver required

Radar sensor (p. 215)

WARNING

Adaptive cruise control is not a collision

avoidance system. The driver must inter-

vene if the system does not detect a vehi-

cle in front.
The adaptive cruise control does not brake

for humans or animals, and not for small

vehicles such as bicycles and motorcy-

cles. Nor for low trailers, oncoming, slow

or stationary vehicles and objects.
Do not use the adaptive cruise control, for

example, in city traffic, in dense traffic, 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.

Distance to the vehicle ahead (p. 210) is

measured primarily by a radar sensor

(p. 215). The cruise control function regulates

the speed with acceleration and braking. It is

normal for the brakes to emit a low sound

when they are being used by the adaptive

cruise control.

WARNING

The brake pedal moves when the adaptive

cruise control brakes. Do not rest your foot

beneath the brake pedal - it may then

become trapped.

The adaptive cruise control aims to follow the

vehicle ahead in the same lane according to

what the driver set for time interval (p. 210). If

the radar sensor 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 in front

exceeds the stored 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 with large

differences in speed, or if the vehicle in front

brakes heavily. Due to limitations in the radar

sensor (p. 215) braking may come unexpect-

edly or not at all.

The adaptive cruise control can be activated

to follow another vehicle at speeds from
30 km/h

up to 200 km/h. If the speed falls

below 30 km/h or if the engine speed

becomes too low, the cruise control is set in

standby mode (p. 211) at which automatic

braking ceases - the driver must then take

over himself/herself to maintain a safe dis-

tance to the vehicle ahead.

NOTE: The illustration is schematic - details may differ depending on car model.

Queue Assist (p. 212) (in cars with automatic gearbox) can operate in the range 0-200 km/h.

07 Driver support

208

Option/accessory, for more information, see Introduction.

Warning lamp - braking by driver
required
Adaptive cruise control has a braking

capacity that is equivalent to approx. 40% of

the car's braking capacity.

1. Collision warning system warning lamp and

warning sound

If the car needs to be braked more heavily

than the adaptive cruise control capacity and

the driver does not brake, then the warning

lamp and warning sound from the Collision

warning system (p. 230) are used in order to

alert the driver that immediate intervention is

required.

The warning lamp may be difficult to see in

strong sunlight or when wearing sun-

glasses.

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. Do not

wait for a warning without braking when so

required.

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. It may have difficulty in

keeping the correct distance from the vehicle

ahead when driving on steep downhill slopes,

with a heavy load or with a trailer - in which

case, be extra attentive and ready to slow

down.

combined instrument panel

as 1-5 horizontal lines - the

more lines the longer the

time interval. One line corre-

sponds to approximately 1 second to the

vehicle in front, 5 lines approximately

3 seconds.
To set/change the time distance:

•

Increase or decrease with the steering
wheel buttons

At low speed, when the distances are short,

the adaptive cruise control increases the time

interval slightly.
The adaptive cruise control allows the time

interval to vary noticeably in certain situations

in order to allow the car to follow the vehicle

in front smoothly and comfortably.
Note that a short time interval only allows the

driver a short time to react and take action if

any unforeseen traffic problem should arise.
The same symbol is also shown when Dis-

Only use the time intervals permitted by

local traffic regulations.
If the adaptive cruise control does not

appear to react when activated, this may

be because the time distance to the vehi-

cle in front is preventing an increase in

speed.
The higher the speed the longer the calcu-

lated distance in metres for a given time

interval.

Adaptive cruise control* - temporary

deactivation, and standby mode

The adaptive cruise control can be temporar-

ily deactivated and set in standby mode.

Temporary deactivation/standby mode
To temporarily disengage the adaptive cruise

control and set it in standby mode:

•

Press the steering wheel button

This symbol and the stored speed's

marking then change colour from

GREEN to WHITE.

Standby mode due to driver intervention
The adaptive cruise control is temporarily dis-

engaged and set automatically in standby

mode if:

•

the foot brake is used

•

the clutch pedal is depressed for longer
than 1 minute

•

the gear selector is moved to N position

(automatic gearbox)

•

the driver maintains speed higher than

the stored speed for longer than

1 minute.

The driver must then regulate the speed.
A temporary increase in speed with the accel-

erator 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. Stability system ESC

(p. 196). If any of these systems stops work-

ing, the adaptive cruise control is deactivated

automatically.
In the event of automatic deactivation a signal

will sound and the message

Adaptive cruise

control cancelled

is shown in the combined

instrument panel. The driver must then inter-

vene and adapt the speed and distance to

the vehicle ahead.
An automatic deactivation can be due to:

•

the driver opens the door

•

the driver takes off his seatbelt

•

engine speed is too low/high

•

speed has fallen below 30 km/h

•

wheels lose traction

•

brake temperature is high

•

the radar sensor is covered e.g. by wet

snow or heavy rain (radar waves blocked).

Resume set speed
Adaptive cruise control in standby mode is

reactivated with one press on the steering

wheel button

- the speed is then set to the

last stored speed.

A pronounced increase in speed may

occur after the cruise control has been
reactivated with the

button.

Adaptive cruise control* - overtaking

another vehicle

When the car is following another vehicle and

the driver indicates an impending overtaking
manoeuvre with the direction indicator

, the

adaptive cruise control helps to briefly accel-

erate the car towards the vehicle in front.
This function is active at speeds

above 70 km/h.

WARNING

Be aware that this function can be acti-

vated in more situations other 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 acceler-

Adaptive Cruise Control* - queue

assistance

Queue assistance also provides the adaptive

cruise control with enhanced functionality at

speeds below 30 km/h.

In cars with automatic gearbox the adaptive

cruise control is supplemented with the

queue assistance function (also referred to as

"Queue Assist").
Queue assistance has the following functions:

•

Extended speed range - also below

30 km/h and when stationary

•

Change of target

•

Automatic braking ceases when station-

ary

•

Automatic activation parking brake.

Note that the lowest programmable speed for

the adaptive cruise control is 30 km/h - even

though it is capable of following another vehi-

cle down to a standstill, a speed lower than

30 km/h cannot be selected/stored.

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

07 Driver support

}}

213

Extended speed range

In order to activate the adaptive cruise

control, the driver's door must be closed

and the driver must be wearing the seat-

belt.

With an automatic gearbox, the adaptive

cruise control can follow another vehicle

within the range 0-200 km/h.

A vehicle in front must be within a reason-

able distance in order to enable activation

of the adaptive cruise control at a speed

lower than 30 km/h.

For shorter stops in connection with inching

in slow traffic or at traffic lights driving is

automatically 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

driver must then reactivate it in one of the fol-

lowing ways:

•

Press the steering wheel button

•

Depress the accelerator pedal.

> The adaptive cruise control will then

resume following the vehicle in front.

The Queue Assist function can hold the car

stationary for a maximum of 4 minutes -

then the parking brake is applied and the

adaptive cruise control is disengaged.

•

The parking brake must be released

before the adaptive cruise control can

be reactivated.

Change of target

If the target vehicle in front suddenly turns then

there may be stationary traffic in front.

When the adaptive cruise control is following

another vehicle at speeds below 30 km/h 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 follow-

ing another vehicle at speeds in excess of

30 km/h and the target is changed from a

moving vehicle to a stationary vehicle, the

adaptive cruise control will ignore the sta-

tionary vehicle and instead select the

stored speed.

•

The driver must 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 and the

adaptive cruise control is uncertain

whether the target object is a stationary

vehicle or some other object, e.g. a speed

bump.

•

when the speed is below 5 km/h and the

vehicle in front turns off so the adaptive

cruise control no longer has a vehicle to

follow.

Termination of automatic braking at a
standstill
In certain situations, queue assistance stops

automatic braking at a standstill. This means

that the brakes are released and the car may

start to roll - the driver must therefore inter-

vene and brake the car himself/herself in

order to maintain its position.

07 Driver support

•

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

position

•

the driver sets the adaptive cruise control

in standby mode.

Automatic activation parking brake
In certain situations queue assistance applies

the parking brake in order to keep the car

remaining stationary.

Radar sensor

The function of the radar sensor is to detect

cars or larger vehicles in the same direction,

in the same lane.

The radar sensor is used by the following

functions:

•

Distance Warning*

•

Adaptive cruise control*

•

Collision Warning System with Auto

Brake and Cyclist and Pedestrian Detec-

tion*

IMPORTANT

In the event of visible damage to the car's

grille, or if you suspect that the radar sen-

sor may be damaged:

•

Contact a workshop - an authorised

Volvo workshop is recommended.

The function may completely or partially

disappear - or malfunction - if the grille,

the radar sensor or its bracket is damaged

or has loosened.

Modification of the radar sensor could result

in it being illegal to use.

Radar sensor - limitations

A radar sensor (p. 215) has certain limitations

- due to its limited field of vision for example.

The capacity of the adaptive cruise control to

detect a vehicle in front is significantly

reduced if:

•

the speed of vehicles in front is signifi-

cantly different from your own speed

•

its radar sensor becomes blocked - e.g.

in heavy rain or slush, or if other objects

have collected in front of the radar sen-

sor.

clean - see subheading "Maintenance"

Keep the area in front of the radar sensor

(p. 234).

Field of vision
The radar sensor has a limited field of vision.

In some situations another vehicle is not

detected, or the detection is made later than

expected.

ACC field of vision.

Sometimes the radar sensor is late at

detecting vehicles at close distances -

e.g. a vehicle that drives in between the

car and vehicles in front.
Small vehicles, such as motorcycles, or

vehicles not driving in the centre of the

lane can remain undetected.
In bends the radar sensor may detect the

wrong vehicle or lose a detected vehicle

from view.
