tracing and action

If the combined instrument panel shows the mes-
sage

Radar blocked See manual

then it

means that the adaptive cruise control's radar
sensor (p. 216) cannot detect other vehicles in
front of the car.

This message indicates that neither of the func-
tions for Distance Alert (p. 199) or Collision
Warning with Auto Brake (p. 228) are working.

The following table presents examples of possi-
ble causes for a message being shown along
with the appropriate action:

Cause

Action

The radar surface in the grille is dirty or covered with ice or snow.

Clean the radar surface in the grille from dirt, ice and snow.

Heavy rain or snow blocking the radar signals.

No action. Sometimes the radar does not work during heavy rain or snowfall.

Water or snow from the road surface swirls up and blocks the radar
signals.

No action. Sometimes the radar does not work on a very wet or snowy road sur-
face.

The radar surface has been cleaned but the message remains.

Wait. It could take several minutes for the radar to sense that it is no longer
blocked.

or larger vehicles in the same direction, in the
same lane.

The radar sensor is used by the following func-
tions:

•

Distance Warning

•

Adaptive cruise control

•

Collision Warning with Auto Brake and
Pedestrian Detection

IMPORTANT

In the event of visible damage to the car's
grille, or if you suspect that the radar sensor
may be damaged:

•

Contact a workshop - an authorised
Volvo workshop is recommended.

The function may completely or partially dis-
appear - or malfunction - if the grille, the
radar sensor or its bracket is damaged or has
loosened.

Radar sensor - limitations

A radar sensor (p. 216) 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 significantly
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 sensor.

Keep the surface in front of the radar sensor
clean.

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.

DRIVER SUPPORT

* Option/accessory.

217

ACC field of vision.

Sometimes the radar sensor is late at detect-
ing vehicles at close distances - e.g. a vehicle
that drives in between the car and vehicles in
front.
Small vehicles, such as motorcycles, or vehi-
cles 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.

WARNING

The driver must always be observant with

regard to the traffic conditions and intervene

when the adaptive cruise control is not main-

taining a suitable speed or suitable 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 control is

being used.

WARNING

Accessories or other objects such as auxiliary

lamps must not be fitted in front of the grille.

WARNING

Adaptive cruise control is not a collision avoid-

ance system. The driver must intervene if the

system does not detect a vehicle in front.
The adaptive cruise control does not brake for

humans or animals, and not for small vehicles

such as bicycles and motorcycles. Nor for

oncoming, slow or stationary vehicles and

objects.
Do not use the adaptive cruise control, for

example, in city traffic, in dense traffic, at junc-

tions, 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.

City Safety™

City Safety

™ is a function for helping the driver

to avoid a collision when driving in queues,
amongst other things, when changes in the traf-
fic ahead, combined with a lapse in attention,
could lead to an incident.

The City Safety

™ function is active at speeds

below 50 km/h (30 mph) and it helps the driver
by automatically braking the car in the event of
imminent risk of collision with vehicles in front,
should the driver not react in time by braking
and/or steering away.

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.

City Safety

™ is designed to be activated as late

as possible in order to avoid unnecessary inter-
vention.

City Safety

™ must not be used as an excuse for

the driver to change his/her driving style. If the
driver solely relies on City Safety

™ to do the

braking, there might be a risk of a collision
sooner or later.

The driver or passengers normally only notice City
Safety

™ if a situation arises where the car is

extremely close to being in a collision.

* (p. 228) these two systems

complement each other.

IMPORTANT

Maintenance and replacement of City
Safety

™ components must only be per-

formed by a workshop - an authorised Volvo
workshop is recommended.

WARNING

City Safety

™ does not engage in all driving

situations or traffic, weather or road condi-

tions.
City Safety

™ does not react to vehicles driv-

ing in a different direction from the car, to

small vehicles and motorcycles or to people

and animals.
City Safety

™ can prevent collision at a speed

difference of less than 15 km/h (9 mph) - at

a higher speed difference, it is only possible

to reduce collision speed. In order to obtain

full brake function, the driver must depress

the brake pedal.
Never wait for City Safety

™ to engage. The

driver always bears responsibility for maintain-

ing the proper distance and speed.

City Safety™ - function

City Safety

™ detects the traffic in front of the

car with a laser sensor (p. 225) fitted in the top
edge of the windscreen. If there is an imminent
risk of collision, City Safety

™ will automatically

brake the car, which may be experienced as
heavy braking.

Laser sensor transmitter and receiver window

If the speed difference is 4-15 km/h (3-9 mph)
in relation to the vehicle in front then City
Safety

™ can completely avoid a collision.

City Safety

™ activates a short, sharp braking and

stops the car in normal circumstances, just
behind the vehicle in front. For most drivers this is
well outside normal driving style and may be
experienced as being uncomfortable.

If the difference in speed between the vehicles is
greater than 15 km/h (9 mph) then City Safety

™

may not avoid the collision on its own - to obtain
full brake force, the driver must depress the
brake pedal and this could then make it possible
to avoid a collision, even at speed differences
above 15 km/h (9 mph).

When the function is activated and brakes, the
combined instrument panel shows a message
(p. 227) to the effect that the function is/has
been active.

When City Safety

™ brakes, the brake lights

come on.

City Safety™ - limitations

The sensor in City Safety

™ is designed to

detect cars and other large vehicles in front of
the car irrespective of whether it is day or night.

However, the function does have some limita-
tions.

The sensor's limitations mean that City Safety

™

has poorer functionality - or none at all - in e.g.
heavy snowfall or rain, dense fog, dust storms or
white-out situations. Misting, dirt, ice or snow on
the windscreen may also disrupt the function.

Low-hanging objects, e.g. a flag/pennant for pro-
jecting load, or accessories such as auxiliary
lamps and bull bars that are higher than the bon-
net limit the function.

The laser light from the sensor in City Safety

™

measures how the light is reflected. The sensor
cannot detect objects with low reflection capacity.
The rear sections of the vehicle generally reflect
the light sufficiently thanks to the number plate
and rear light reflectors.

On slippery road surfaces the braking distance is
extended, which may reduce the capacity of City
Safety

™ to avoid a collision. In such situations

the ABS

and ESC

systems will provide best

possible braking force with maintained stability.

When your own car is reversing, City Safety

™ is

temporarily deactivated.

City Safety

™ is not activated at low speeds -

below 4 km/h (3 mph), which is why the system
does not intervene in situations where a vehicle
in front is being approached very slowly, e.g.
when parking.

Driver commands are always prioritised, which is
why City Safety

™ does not intervene in situations

where the driver is steering or accelerating in a
clear manner, even if a collision is unavoidable.

When City Safety

™ has prevented a collision

with a stationary object the car remains stationary
for a maximum of 1.5 seconds. If the car is
braked for a vehicle in front that is moving, then
speed is reduced to the same speed as that
maintained by the vehicle in front.

On a car with manual gearbox the engine stops
when City Safety

™ has stopped the car, unless

the driver manages to depress the clutch pedal
beforehand.

•

Keep the windscreen surface in front of
the laser sensor (p. 225) free from ice,
snow and dirt. For an illustration of sen-
sor location, see City Safety

™ - function

(p. 222).

•

Do not affix or mount anything on the
windscreen in front of the laser sensor

•

Remove ice and snow from the bonnet -
snow and ice must not exceed a height
of 5 cm.

Fault tracing and action

If the message (p. 227)

Windscreen sensors

blocked See manual

is shown in the combined

instrument panel it indicates that the laser sensor
is blocked and cannot detect vehicles in front of
the car. This means that City Safety

™ is not

operational.

The

Windscreen sensors blocked See

manual

message is not shown for all situations

in which the laser sensor is blocked. The driver
must therefore be diligent about keeping the
windscreen and area in front of the laser sensor
clean.

The following table presents possible causes for
the message being shown, along with sugges-
tions for appropriate action.

Cause

Action

The windscreen surface
in front of the laser sen-
sor is dirty or covered
with ice or snow.

Clean the wind-
screen surface in
front of the sensor
from dirt, ice and
snow.

The laser sensor field of
vision is blocked.

Remove the block-
ing object.

IMPORTANT

If there are cracks, scratches or stone chips in
the windscreen in front of either of the laser
sensor's "windows" and they cover a surface
of approx. 0.5 x 3.0 mm (or larger), then a
workshop must be contacted for replacement
of the windscreen - an authorised Volvo work-
shop is recommended. For an illustration of
sensor location, see City Safety

™ - function

(p. 222).

Failure to take action may result in reduced
performance for City Safety

™.

To avoid the risk of failed, deficient or
reduced operation for City Safety

™, the fol-

lowing also applies:

•

Volvo recommends that you do not repair
cracks, scratches or stone chips in the
area in front of the laser sensor - instead,
the whole windscreen should be
replaced.

•

Before replacing a windscreen, contact
an authorised Volvo workshop to verify
that the correct windscreen is ordered
and fitted.

•

The same type or Volvo-approved wind-
screen wipers must be fitted during
replacement.

City Safety™ - laser sensor

The City Safety

™ function includes a sensor

which transmits laser light. Contact a qualified
workshop in the event of a fault or if the laser
sensor needs servicing - an authorised Volvo
workshop is recommended. It is absolutely
essential to follow the prescribed instructions
when handling the laser sensor.

The following two labels relate to the laser sen-
sor:

The upper label in the figure describes the laser
beam's classification:

•

Laser radiation - Do not look into the laser
beam with optical instruments - Class 1M
laser product.

The lower label in the figure describes the laser
beam's physical data:

•

IEC 60825-1:1993 + A2:2001. Complies
with FDA (U.S. Food Administration) stand-
ards for laser product design with the excep-
tion of deviations in accordance with "Laser

WARNING

If any of these instructions are not followed

then there is a risk of eye injury!

•

Never look into the laser sensor (which
emits spreading invisible laser radiation)
at a distance of 100 mm or closer with
magnifying optics such as a magnifying
glass, microscope, lens or similar optical
instruments.

•

Testing, repair, removal, adjustment
and/or replacement of the laser sensor's
spare parts must only be carried out by a
qualified workshop - we recommend an
authorised Volvo workshop.

•

To avoid exposure to harmful radiation, do
not carry out any readjustments or main-
tenance other than those specified here.

•

The repairer must follow specially drawn
up workshop information for the laser
sensor.

•

Do not remove the laser sensor (this
includes removing the lenses). A removed
laser sensor fulfils laser class 3B as per
standard IEC 60825-1. Laser class 3B is
not eye-safe and therefore entails a risk
of injury.

•

The laser sensor's connector must be
unplugged before removal from the wind-
screen.

•

The laser sensor must be fitted onto the
windscreen before the sensor's connec-
tor is plugged in.

•

The laser sensor transmits a laser light
when the remote control key is in key
position II (p. 81) even if the engine is
switched off.
