Volvo XC70 (2016 year). Instruction - part 13

City Safety – introduction (p. 202)

The function of aftermarket laser detectors

may be affected by City Safety's laser sen-

sor.

WARNING

The laser sensor emits light when the igni-

tion is in mode II or higher, even if City

Safety™ has been switched off.

WARNING

Eye injury may occur if any of the following

points are not followed:

•

It is essential that all pertinent instruc-

tions be followed when handling laser

instruments. Testing, repairing, remov-

ing, adjusting and/or replacing any

components in the laser sensor may

only be done by a trained and qualified

Volvo service technician.

•

Do not remove the laser sensor

(including removal of the lenses). A

laser sensor that has been removed

belongs to laser class 3B according to

standard IEC 60825-1. Devices in laser

class 3B present a risk of injury to the

eyes.

•

The laser sensor’s connector must be

disconnected before the sensor is

removed from the windshield.

•

The laser sensor must be mounted in

place on the windshield before con-

necting the sensor’s connector.

•

Do not view the laser sensor (which

emits spreading, invisible laser beams)

with optical instruments from a dis-

tance of less than 4 inches (100 mm).

Collision warning – introduction

Pedestrian and Cyclist Detection with Full

Auto Brake is designed to assist the driver if

there is a risk of a collision with a pedestrian,

a cyclist, a vehicle ahead that is at a standstill

or one that is moving in the same direction as

your vehicle.

This system consists of the following three

functions:

•

Collision Warning warns the driver of a

potential collision situation.

•

Brake Support helps the driver brake

efficiently in a critical situation.

•

Auto-brake brakes the vehicle automati-

cally if a collision with a pedestrian, a

cyclist or another vehicle cannot be avoi-

ded and the driver does not apply the

brakes in time or steer around the per-

son/vehicle. Auto-brake can help prevent

a collision or reduce the speed at which a

collision occurs.

Since Pedestrian and Cyclist Detection with

Full Auto Brake is activated in circumstances

where the driver should have begun braking

much sooner, the system will not be able to

assist the driver in all situations.
This system is designed to activate as late as

possible to help avoid unnecessary interven-

tion.
The system should not be used in such a way

that the driver changes his/her way of operat-

ing the vehicle. If the driver relies entirely on

the system, the chances of an accident even-

tually occurring increase considerably.
The Pedestrian and Cyclist Detection with Full

Auto Brake and City Safety™ systems sup-

plement each other. See City Safety – intro-

duction (p. 202) for detailed information about

City Safety™.

WARNING

No automatic system can be guaranteed

to function 100% correctly in all situations.

For that reason, never test the Auto-brake

system by driving toward a person or

object. This could result in serious injury or

death.

Option/accessory, for more information, see Introduction.

WARNING

•

Pedestrian and Cyclist Detection with

Full Auto Brake does not work in all

driving, traffic, weather and road con-

ditions. It does not react to vehicles

not traveling in the same direction as

your vehicle.

•

Pedestrian and Cyclist Detection with

Full Auto Brake does not react to ani-

mals.

•

Warnings are only provided when the

risk of collision is high. The "Function"

section provides information about

limitations that the driver must be

aware of before using Collision Warn-

ing.

•

Pedestrian and Cyclist Detection with

Full Auto Brake will not provide a

warning or brake the vehicle for

pedestrians or cyclists at speeds

above 50 mph (80 km/h).

WARNING

•

Pedestrian and Cyclist Detection with

Full Auto Brake will not provide a

warning or brake the vehicle for

pedestrians in darkness or in tunnels,

even if there is street lighting in the

area.

•

The auto-brake function can help pre-

vent a collision or reduce the speed at

impact but the driver should always

apply the brakes for the best possible

braking effect, even if auto-brake is

actively applying the brakes.

•

Never wait for a collision warning. This

system is designed to be a supple-

mentary driving aid. It is not, however,

intended to replace the driver's atten-

tion and judgement. The driver is

responsible for maintaining a safe dis-

tance and speed, even when the colli-

sion warning system is in use.

•

Maintenance of the Pedestrian and

Cyclist Detection with Full Auto Brake

system's components must only be

performed by a trained and qualified

Volvo technician.

Audio-visual warning signals, collision risk

Radar sensor

Camera

Collision Warning
The radar sensor and the camera work

together to detect a pedestrian, a cyclist, sta-

tionary vehicles and vehicles that are moving

in the same direction as your vehicle. If there

is a risk of collision with a vehicle, a cyclist or

a pedestrian, the driver is alerted by a flash-

ing red warning light and an audible warning

signal. The system is active at speeds above

3 mph (4 km/h).

Brake Support
If the risk of collision continues to increase

after the collision warning has been given,

Brake Support is activated. Brake Support

prepares the brake system to react quickly,

and the brakes are applied slightly. This may

be experienced as a light tug.
If the brakes are applied quickly, full braking

effect will be provided. Brake Support also

increases brake force if the system deter-

mines that the driver has not applied ade-

quate pressure on the brake pedal.

Auto-brake
If a collision is imminent and the driver has

not applied the brakes or begun to steer

around the vehicle, pedestrian or a cyclist,

the auto-brake function is activated without

the driver pressing the brake pedal. Full brake

force is applied to help reduce the vehicle’s

speed when the collision occurs or limited

brake force is applied if this is sufficient to

avoid the collision.

The auto-brake and brake support func-

tions are always on and cannot be turned

off.

Collision warning* – Cyclist detection

The system can detect a cyclist and auto-

brake if certain parameters are fulfilled.

Optimal example of what the system considers

to be a cyclist: clear body/bike contours, straight

from behind and directly in front of the vehicle

In order to help detect a cyclist, the system

has to receive clear information about the

contours of the cyclist's body and the bike. It

has to able to clearly detect the bike, the

cyclist's head, arms, shoulders, legs and

upper and lower body combined with the per-

son's pattern of movement when cycling.

The function only detects cyclists from behind

who are moving in the same direction as your

vehicle

The Cyclist Detection feature requires the fol-

lowing in order to function:

•

The cyclist must be an adult riding an

"adult-size" bike

•

The bike must be equipped with an

approved and clearly visible rear-facing

red reflector that is mounted at least

27 in. (70 cm) above the road surface

•

The feature can only detect a cyclist

straight from behind and who is moving in

the same direction as your vehicle

•

A cyclist who is to the left or right of your

vehicle may be detected late or not at all.

•

The camera's capacity to see a cyclist at

dawn or dusk is limited, much as it is for

the human eye.

•

The camera's function is deactivated and

will not detect a cyclist in darkness or in

tunnels, even if there is street lighting in

the area.

•

For optimal cyclist detection, City

Safety™ must be activated.

WARNING

Pedestrian and Cyclist Detection with Full

Auto Brake 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 always

responsible for operating the vehicle in a

safe manner.

The system cannot detect a bike/cyclist if:

•

He/she is wearing loose-fitting clothing

that may obscure body contours

•

The bike is approaching your vehicle

from the side

•

The bike is not equipped with a rear-

facing red reflector

•

The bike is carrying large objects

•

Most of the cyclist's body or the bike

itself cannot be "seen" by the system's

camera

Collision warning* – Pedestrian

detection

The system cannot identify all pedestrians

The Pedestrian and Cyclist Detection with Full

Auto Brake system can only identify and

detect a pedestrian who is standing upright.

This person can be standing still, walking or

running.
This means that the system has to be able to

identify a person's head, arms, shoulders,

legs, the upper and lower parts of the body

and a person's pattern of movement when

walking or running.
If parts of the body are not visible to the cam-

era, the system cannot detect the pedestrian.
The following conditions apply:

•

In order to detect a pedestrian, the sys-

tem must have a full view of the person's

entire body and the person must be at

least 32 in. (80 cm) tall.

•

The system cannot detect a pedestrian

carrying a large object.

•

The camera's capacity to see a pedes-

trian at dawn or dusk is limited, much as

it is for the human eye.

•

The camera's function is deactivated and

will not detect a pedestrian in darkness or

in tunnels, even if there is street lighting in

the area.

WARNING

•

Pedestrian and Cyclist Detection with

Full Auto Brake is designed to be a

supplementary driving aid. It is not,

however, intended to replace the driv-

er's attention and judgement. The

driver is always responsible for operat-

ing the vehicle in a safe manner.

•

The system cannot detect all pedes-

trians in all situations, such as in dark-

ness/at night and cannot detect parti-

ally hidden pedestrians, people who

are less than approx. 32 in. (80 cm)

tall, or people wearing clothing that

obscures the contours of their bodies.

Collision warning* – limitations

Strong sunlight, reflections, extreme light

contrasts, the use of sunglasses, or if the

driver is not looking straight ahead may make

the visual warning signal in the windshield dif-

ficult to see. For this reason, always activate

the audible warning signal.
Slippery driving conditions increase braking

distance, which can reduce the system's

capacity to avoid a collision. In these condi-

tions, the ABS and stability systems provide

the best possible braking effect while helping

to maintain stability.

tions, see Adaptive Cruise Control – limita-

The visual warning signal may be tempo-

rarily disengaged in the event of high pas-

senger compartment temperature due to

strong sunlight, etc. If this occurs, the

audible warning signal will be used, even if

it has been deactivated in the menu sys-

tem.

WARNING

•

In certain situations, the system can-

not provide warnings or warnings may

be delayed if traffic conditions or other

external factors make it impossible for

the radar sensor or camera to detect a

pedestrian, a cyclist or a vehicle

ahead.

•

Warnings may not be provided if the

distance to the vehicle ahead is short,

or if movements of the steering wheel/

brake pedal are great, such as during

active driving.

•

The sensor system has a limited range

for pedestrians/cyclists and provides

warnings and braking effect most

effectively at speeds up to 30 mph

(50 km/h). For stationary or slow-mov-

ing vehicles, the system functions best

if your vehicle’s speed is below

approximately 45 mph (70 km/h).

•

Warnings for stationary or slow-mov-

ing vehicles may not be provided in

dark conditions or in poor visibility.

The Pedestrian and Cyclist Detection with Full

Auto Brake system uses the same radar sen-

sors as Adaptive Cruise Control. For more

information on the radar sensor and its limita-

tions (p. 193).

warning distance can be reduced (see Col-

If warnings are given too frequently, the

lision warning* – operation (p. 212)). This

causes the system to provide later warn-

ings, which decreases the total number of

warnings provided.

WARNING

•

The system is not activated at speeds

under approx. 2 mph (4 km/h). There-

fore, it will not brake your vehicle if you

approach a vehicle ahead at very low

speed, such as when parking.

•

The driver's actions always have high-

est priority and override the Pedestrian

and Cyclist Detection with Full Auto

Brake system. This means that the

system will not intervene in situations

where the driver is actively steering,

braking or pressing the accelerator

pedal, even if a collision is imminent.

•

When Auto-brake has prevented a col-

lision with a stationary object, your

vehicle will remain at a standstill for

approx. 1.5 seconds. If your vehicle

has been braked for a moving vehicle

ahead, your vehicle's speed will be

reduced to the same speed as that

vehicle's.

The camera’s limitations

The camera has the same limitations as the

human eye.

The camera is used by Pedestrian and Cyclist

ing – introduction (p. 209), Active High Beams

(Active high beams (AHB)* (p. 90)), Road Sign

Information (Road Sign Information (RSI)* –

introduction (p. 179)) and Driver Alert System

(Driver Alert System (p. 222)) with Lane

Departure Warning.

•

To help protect the camera in very hot

conditions, it may be temporarily

switched off for approximately 15

minutes after the engine has been

started.

•

Keep the section of the windshield in

front of the camera clean and free of

ice, snow, or condensation.

WARNING

•

The camera has the same type of limi-

tations as the human eye, i.e., it can-

not see as well in heavy snowfall or

rain, thick fog or in heavy blowing dust

or snow. In such conditions, systems

depending on the camera may experi-

ence greatly reduced functionality or

may be temporarily deactivated.

•

Never place any objects, decals, etc.,

on the windshield in front of the cam-

era. This could reduce or block the

camera’s function, and could cause

one or more of the systems that utilize

the camera to stop functioning.

•

Strong sunlight, reflections from the

road surface, ice or snow covering the

road, a dirty road surface, or unclear

lane marker lines may drastically

reduce the camera’s capacity to

detect the side of a lane, a pedestrian,

a cyclist or another vehicle.
