City Safety™

WARNING

City Safety⁸⁵can use lights, sound and a

brake pulse warning to alert the driver to

pedestrians, cyclists, larger animals and vehi-

cles.

The 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 function helps the driver by automatically

braking the car in the event of an imminent

risk of collision if the driver does not react in

time by braking and/or swerving.

City Safety is activated in situations where the

driver should have started braking earlier,

which is why it cannot help the driver in every

situation. The function is designed to be acti-

vated as late as possible in order to avoid

unnecessary intervention. Automatic braking

takes place only after or at the same time as

the collision warning.

The driver is advised to read all sec-

tions 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.

Driver support functions are not a sub-

stitute for the driver's attention and

judgement. The driver is always

responsible for ensuring the car is

driven in a safe manner, at the appro-

priate speed, with an appropriate dis-

tance to other vehicles, and in accord-

ance with current traffic rules and reg-

ulations.

•

The driver or passengers are not normally

aware of City Safety - it only intervenes in a

situation where a collision is immediately

imminent.

Subfunctions for City Safety

The steps of City Safety

City Safety carries out three steps in the fol-

lowing order:

City Safety⁸⁶can help to prevent a collision

or reduce the collision speed. The function

consists of several subfunctions.

(p. 338)

1. Collision warning

2. Brake support

3. Auto Brake

Automatic braking in the event of an impe-

ded evasive manoeuvre with City Safety

(p. 337)

Ability to reduce speed

If the speed difference between the driver's

car and the obstacle is greater than the follow-

ing specified speeds, the City Safety auto-

brake function cannot prevent a collision but it

can mitigate the consequences of a collision.

1 - Collision warning

The driver is first warned of a potentially immi-

nent collision.

City Safety in cross traffic (p. 336)

Limitations of City Safety (p. 339)

Messages for City Safety (p. 342)

•

City Safety can detect pedestrians, cyclists or

vehicles that are stationary or moving in the

same direction as the car and are ahead. City

Safety can also detect pedestrians, cyclists or

large animals that are crossing the road in

front of the car.

Vehicles

For a vehicle in front, City Safety can reduce

the speed by up to 60 km/h (37 mph).

Cyclists

For a cyclist, City Safety can reduce the speed

by up to 50 km/h (30 mph).

In the event of a risk of collision with a pedes-

trian, larger animal, cyclist or vehicle, the

driver is alerted by means of a visual, acoustic

and brake pulse warning. There is no brake

pulse warning at lower speeds, sudden driver

braking or acceleration. The brake pulse fre-

quency varies according to the car's speed.

Pedestrians

For a pedestrian, City Safety can reduce speed

by up to 45 km/h (28 mph).

Large animals

In the event of a risk of a collision with a large

animal, City Safety can reduce the car's speed

by up to 15 km/h (9 mph).

The brake function for large animals is primar-

ily intended to reduce the force of the impact

at higher speeds and is most effective at

speeds above 70 km/h (43 mph) but less

effective at lower speed.

The function is not available in all markets.

(p. 338)

2 - Brake support

•

NOTE

If the risk of collision has increased further

after the collision warning then the brake sup-

port is activated.

On cars with manual gearbox, the engine

stops when the Auto-brake function has

stopped the car, unless the driver has man-

aged to depress the clutch pedal before-

hand.

Limitations of City Safety (p. 339)

Seatbelt tensioner (p. 49)

•

Brake support reinforces the driver’s braking

action if the system considers that the braking

is not sufficient to avoid a collision.

3 - Auto Brake

The automatic brake function is activated last.

The driver can always interrupt a braking inter-

vention by firmly depressing the accelerator

pedal.

If in this situation the driver has not yet started

to take evasive action and the risk of collision

is imminent then the automatic braking func-

tion is deployed - this takes place irrespective

of whether or not the driver brakes. Braking

then takes place with full brake force in order

to reduce collision speed, or with limited brake

force if it is sufficient to avoid a collision.

NOTE

When City Safety brakes, the brake lights

come on.

When City Safety is activated and brakes the

vehicle, the driver display shows a text mes-

sage to the effect that the function is/has

been active.

The seatbelt tensioner can be activated in con-

nection with the engagement of the automatic

brake function.

In some situations, the action of Auto-brake

may begin with light braking and then pro-

gress to full brake action.

WARNING

City Safety must not be used by the driver

to change his/her driving style - the driver

must not rely on City Safety alone and

allow it to do the braking.

When City Safety has prevented a collision

with a stationary object, the car remains sta-

tionary in anticipation of positive action by the

driver. If the car has been braked to avoid colli-

sion with a slower vehicle in front, its speed is

reduced to match that of the vehicle in front.

WARNING

No automatic system can guarantee

100% correct function in all situations.

Therefore, never test City Safety by

driving at people, animals or vehicles -

this may cause severe damage and

injury and risk lives.

•

City Safety⁸⁷is always activated, but the

driver can select the warning distance for the

function.

The Late warning distance should therefore

only be used in exceptional cases, as in

dynamic driving.

NOTE

The City Safety function cannot be deacti-

vated. It is activated automatically when

the engine/electric operation is started and

remains switched on until the engine/elec-

tric operation is switched off.

City Safety warns the driver when

there is a risk of a collision, but it can-

not shorten the driver’s reaction time.

•

Even if the warning distance has been

set to Early warnings could be per-

ceived as being late in certain situa-

tions, e.g. when there are large differ-

ences in speed or if vehicles ahead

suddenly brake heavily.

The warning distance determines the sensitiv-

ity of the system and regulates the distance at

which a visual, acoustic and brake pulse warn-

ing should be deployed.

oncoming vehicles and cross traffic in certain

cases.

cyclists wearing clothing that obscures

the body outline.

•

bicycles loaded with large objects.

Warnings and brake interventions could be

late or not occur at all. The driver is always

responsible that the vehicle is driven cor-

rectly and with a safety distance adapted

to the speed.

In order that City Safety shall be able to detect

a vehicle in the dark, the vehicle's front and

rear lights must be working and clearly illumi-

nated.

Examples of what City Safety interprets as a cyclist

— with clear body outline and bicycle outline.

Good performance requires that the system

function that detects a cyclist must receive the

clearest possible information about the body

and bicycle outline, requiring the ability to

identify the bicycle, head, arms, shoulders,

legs, upper and lower body plus a normal

human pattern of movement.

If large parts of the cyclist's body or bicycle

are not visible to the function's camera then

the system cannot detect a cyclist.

For the function to be able to detect a cyclist,

he/she must be an adult and riding a bicycle

designed for adults.

DRIVER SUPPORT

City Safety can also detect pedestrians in the

dark if they are illuminated by the car's head-

Pedestrians

Large animals

WARNING

City Safety is supplementary driver sup-

port, but it cannot detect all pedestrians in

all situations and, for example, cannot see:

partially obscured pedestrians, people

in clothing that hides their body con-

tour or pedestrians shorter than 80 cm

(32 in.).

•

pedestrians if the background contrast

for the pedestrians is poor.

•

Examples of what the system regards as pedestrians

with clear body outlines.

Examples of what City Safety interprets as large ani-

mals - standing still or walking slowly and with clear

body outline.

pedestrians who are carrying larger

objects.

Good performance requires that the system

function that detects a pedestrian must

receive the clearest possible information about

the body outline, requiring the ability to iden-

tify the head, arms, shoulders, legs, upper and

lower body plus a normal human pattern of

movement.

Good performance requires that the system

function that detects a large animal (e.g. elk

and horse) must receive the clearest possible

information about the body outline, requiring

the ability to identify the animal directly from

the side in combination with what is a normal

pattern of movement for the animal.

Warnings and brake interventions could be

late or not occur at all. The driver is always

responsible that the vehicle is driven cor-

rectly and with a safety distance adapted

to the speed.

In order that it shall be possible to detect a

pedestrian there must be a contrast with the

background and this will be affected by such

things as clothes, the background and the

weather. With poor contrast the pedestrian

may either be detected late or not at all, which

may mean that warnings and braking are late

or omitted.

If parts of the animal's body are not visible to

the function's camera then the system cannot

detect the animal.

City Safety can also detect large animals in the

dark if they are illuminated by the car's head-

lamps.

DRIVER SUPPORT

The camera and radar unit's field of view

The camera's field of vision is limited, which is

why pedestrians, large animals, cyclists and

vehicles in some situations cannot be

detected, or they are detected later than

anticipated.

Limitations of City Safety

Driver intervention

Reversing

When your own car is reversing, City Safety is

temporarily deactivated.

The City Safety⁹¹function may have limita-

tions in certain situations.

Surroundings

Low speed

Low objects

City Safety is not activated at very low speeds

- below 4 km/h (3 mph) - and the system

therefore does not intervene in situations

where your car is approaching a vehicle ahead

very slowly, e.g. when parking.

Low-hanging objects, e.g. a flag/pennant for

projecting load, or accessories such as auxili-

ary lamps and bull bars that are higher than

the bonnet limit the function.

Dirty vehicles may be detected later than oth-

ers and if it is dark, motorcycles may be

detected late or not at all.

If a text message in the driver display indicates

that the camera or radar unit is obstructed,

City Safety may be unable to detect pedes-

trians, large animals, cyclists, vehicles or road

lines ahead of the car. This means that the

functionality of City Safety may be reduced.

Skidding

Active driver

On slippery road surfaces the braking distance

is extended, which may reduce the capacity of

City Safety to avoid a collision. In such situa-

tions, the anti-lock brakes and the stability

control ESC⁹²are designed to give the best

possible braking force with maintained stabil-

ity.

Driver commands are always prioritised,

which is why City Safety does not intervene or

postpone warning/intervention in situations

where the driver is steering and accelerating in

a decisive manner, even if a collision is

unavoidable.

However, an error message is not shown in all

situations where the windscreen sensors are

obstructed. The driver must therefore take

care to keep the area of windscreen in front of

the camera and radar unit clear.

Active and aware driving behaviour can there-

fore delay a collision warning and intervention

in order to minimise unnecessary warnings.

Oncoming light

The visual warning signal in the windscreen

may be difficult to notice in the event of strong

sunlight, reflections, when sunglasses are

being worn or if the driver is not looking

straight ahead.

IMPORTANT

Maintenance of driver support components

must only be performed at a workshop –

an authorised Volvo workshop is recom-

mended.

Heat

temperature, caused by e.g. strong sunlight,

the visual warning signal in the windscreen

may be temporarily disengaged.

Important warnings

WARNING

Warnings and brake interventions

could be implemented late or not at all

if a traffic situation or external influ-

ences mean that the camera and radar

unit cannot detect pedestrians,

cyclists, large animals or vehicles cor-

rectly.

•

Warnings and brake interventions for

pedestrians and cyclists are deacti-

vated at vehicle speeds exceeding

80 km/h (50 mph).

•

Driver supports only warn of obstacles

which their radar unit has detected –

hence a warning may not be given, or it

may be given with a certain delay.

Do not place, stick or mount anything

on the outside or inside of the wind-

screen in front of or around the camera

and radar unit — this can interfere with

camera-dependent functions.

Never wait for a warning or interven-

•

tion. Apply the brakes when the situa-

tion requires.

For vehicles to be detected at night,

their headlamps and rear lamp cluster

must be switched on and shining

clearly.

•

Objects, snow, ice or dirt in the area of

the camera sensor may reduce its func-

tionality, fully deactivate it or give

incorrect function response.

•

The camera and radar unit has a limited

range for pedestrians and cyclists. The

system can provide effective warnings

and brake interventions as long as the

relative speed is below 50 km/h

(30 mph). For stationary or slow-mov-

ing vehicles, warnings and brake inter-

ventions are effective at vehicle speeds

up to 70 km/h (43 mph). Speed reduc-

tion for large animals is less than 15

km/h (9 mph) and can be achieved at

vehicle speeds above 70 km/h

(43 mph). The warning and brake inter-

vention for large animals is less effec-

tive at lower speeds.
