is shown in the

instrument panel. The driver must then inter-

vene and adapt the vehicle's speed to the

surrounding traffic and regulate the distance

to the vehicle ahead.
An automatic switch to standby mode may be

caused if:

•

engine speed (rpm) is too high/low

•

The driver's door is opened

•

The driver unbuckles his/her seat belt

•

the vehicle's speed goes below 18 mph

(30 km/h)

Adaptive Cruise Control – passing

another vehicle

Passing another vehicle
If your vehicle’s speed is being regulated by

ACC and the driver indicates that he/she

would like to pass the vehicle ahead by using

the left turn signal, ACC can assist by accel-

erating briefly.
This function is active at speeds above

approximately 45 mph (70 km/h).

WARNING

Please be aware that this function will also

cause the vehicle to accelerate briefly in

certain situations other than passing

another vehicle, for example using the left

turn signal to indicate a lane change or a

turn toward a highway exit at speeds

above approximately 45 mph (70 km/h).

Adaptive Cruise Control (ACC) –

Queue Assist

Queue Assist is an added ACC feature that is

linked to your vehicle's automatic transmis-

sion.

Introduction
Queue Assist is an added ACC feature that is

linked to your vehicle's automatic transmis-

sion.
Queue Assist consists of the following func-

tions:

•

Enhanced speed interval (including when

the vehicle is at a complete stop or is

moving at speed below 18 mph

(30 km/h))

•

Automatic standby mode when ACC

changes target vehicles

•

No automatic braking when at a standstill

•

The parking brake is applied automati-

cally

Please note that the lowest speed that can be

set is 18 mph (30 km/h), although ACC can

maintain a set speed/distance to a vehicle

ahead down to a standstill. Queue Assist

consists of the following features:

Enhanced speed interval

The driver's door must be closed and the

driver's seat belt must be fastened before

ACC can be put in active mode. If the driv-

er'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 rea-

sonable 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 vehi-

cle 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 automat-

ically go into standby mode.

07 Driver support

192

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

vehicle ahead at the set time interval.

the parking brake (see Parking brake –

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

general information (p. 268)).

Automatic standby mode when ACC
changes target vehicles

If the vehicle ahead turns suddenly, there may be

a stationary 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 sys-

tem 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 acceler-

ate 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 vehicle 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 park-

ing 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. 176))

•

ACC has kept the vehicle at a standstill

for more than 2 minutes

•

The engine has been switched off

•

The brakes have overheated

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 technician as soon as possible.

The radar sensor may only function

partially (or not at all) if it is damaged

or is not securely fastened 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 vehi-

cles ahead is impeded:

•

if the radar sensor is obstructed and can-

not 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 signifi-

cantly different from your own speed.

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.

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

vehicles 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 tar-

get vehicle.

WARNING

•

Adaptive Cruise Control cannot cover

all driving situations and traffic,

weather and road conditions. The

"Function" section provides informa-

tion about limitations that the driver

must be aware of before using this

feature.

•

This system is designed to be a sup-

plementary driving aid. It is not, how-

ever, intended to replace the driver's

attention and judgement. The driver is

responsible for maintaining a safe dis-

tance 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

qualified Volvo technician.

WARNING

•

Adaptive Cruise Control is not a colli-

sion 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 situa-

tions, 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.

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

approximately 30 mph (50 km/h) and assists

the driver by applying the brakes automati-

cally, thereby avoiding or helping to reduce

the effects of a collision.
City Safety™ is designed to intervene as late

as possible to help avoid unnecessary activa-

tion.
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 col-

lision is imminent.
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. 209) .

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

driving situations or in all traffic,

weather or road conditions.

WARNING

•

City Safety™ only reacts to vehicles

traveling 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 differ-

ence 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 vehi-

cle 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 vehi-

cle 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 informa-

tion display to indicate that the system is/has

been active.

City Safety – introduction (p. 202)

•

When City Safety™ applies the

brakes, the brake lights will illuminate.

•

In cases where City Safety™ has stop-

ped the vehicle, the system will then

release the brakes. The driver must

apply the brakes to keep the vehicle at

a standstill.

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. Condensa-

tion, dirt, ice or snow on the windshield

may also interfere with the sensor’s func-

tion.

The sensor used by City Safety™ is designed

to detect cars and other larger motor vehicles

ahead of your vehicle in both daylight and

darkness.
Objects such as warning flags hanging from

long objects on the roof or accessories such

as auxiliary 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 increa-

ses on slippery road surfaces, which may

reduce City Safety’s capacity to avoid a colli-

sion. In situations like this, the stability sys-

tem (see Stability system – introduction

(p. 175)) will help provide the best possible

braking capacity and stability.
City Safety™ emits a laser beam and meas-

ures the way in which the light is reflected.

07 Driver support

}}

205

Therefore, vehicles or objects with low-reflec-

tive 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.

etc., see City Safety – function

•

Keep the windshield in front of the

laser sensor free of ice, snow, dirt,

(p. 203).

•

Snow or ice on the hood deeper than

2 inches (5 cm) may obstruct the sen-

sor. Keep the hood free of ice and

snow.

•

Do not mount or in any way attach

anything on the windshield that could

obstruct the laser sensor.
