City Safety steering assistance

limitations during evasive

maneuvers

City Safety steering assistance may have lim-
ited functionality in certain situations and not
intervene, e.g.:

•

at speeds outside the range of
50-100 km/h (30-62 mph)

•

if the driver does not take evasive action

•

if speed-dependent power steering wheel
resistance is working at reduced power –
e.g. during cooling due to overheating.

NOTE

The function uses the vehicle's camera and
radar sensor, which has certain general
limitations.

Automatic braking during delayed

evasive maneuvers with City

Safety

City Safety

 can assist the driver by auto-

matically braking the vehicle when it is not
possible to avoid a collision by steering alone.

City Safety assists the driver by periodically
attempting to predict possible "escape
routes" to the sides of the vehicle in the event
a slow-moving or stationary vehicle were to be
detected at a late stage.

Your vehicle (1) cannot detect any potential escape

routes for veering away from the vehicle ahead (2)

and may therefore apply the brakes at an earlier

stage.

City Safety will not intervene to automatically
apply the brakes if it is possible for the driver
to avoid a collision by steering the vehicle.

However, if City Safety determines that an
evasive maneuver would not be possible due
to traffic in the adjacent lane(s), the function
can assist the driver by automatically starting
to apply the brakes at an earlier stage.

City Safety braking for oncoming

vehicles

City Safety can help you apply the brakes for
an oncoming vehicle in your lane.

If an oncoming vehicle veers into your lane
and a collision is unavoidable, City Safety can
help reduce your vehicle's speed to attempt to
mitigate the force of the collision.

Own vehicle

Oncoming vehicles

The following criteria must be met for the
function to work:

•

your vehicle's speed must be above
4 km/h (3 mph)

•

the road must be straight

•

your lane must have clear side lane mark-
ings

•

your vehicle must be positioned straight in
your lane

•

the oncoming vehicle must be positioned
within your vehicle's lane markings

•

the oncoming vehicle's headlights must
be on

•

the function can only handle “front-to-
front” collisions

•

the function can only detect vehicles with
four wheels.

WARNING

Warnings and brake interventions due to

an imminent collision with an oncoming

vehicle always come very late.

City Safety limitations

City Safety

81

 functionality may be reduced in

certain situations.

Surroundings

Low objects

Hanging objects, such as flags for overhang-
ing loads or accessories such as auxiliary
lights or front protective grids that extend
beyond the height of the hood, may limit City
Safety functionality.

Slippery road conditions

The extended braking distance on slippery
roads may reduce City Safety's capacity to
help avoid a collision. In these types of situa-
tions, the Anti-lock Braking System and Elec-
tronic Stability Control (ESC

82

) are designed

for optimal braking power with maintained
stability.

Backlighting

The visual warning signal in the windshield
may be difficult to detect in bright sunlight, if
there are reflections, or if the driver is wearing
sunglasses or not looking straight ahead.

Heat

If the temperature in the passenger compart-
ment is high due to e.g. bright sunlight, the
visual warning signal in the windshield may be
temporarily disabled.

Camera and radar sensor's field of vision

The camera's field of vision is limited and in
certain situations, it may be unable to detect
pedestrians, large animals, cyclists or vehicles,
or it may detect them later than expected.

Vehicles that are dirty may be detected later
than clean vehicles, and in dark conditions,
motorcycles may be detected late or not at all.

If a text message displayed in the instrument
panel indicates that the camera or radar sen-
sor is obstructed, it may be difficult for City
Safety to detect pedestrians, large animals,
cyclists, vehicles or lane markings in front of
the vehicle. City Safety functionality may
therefore be reduced.

Text messages may not be displayed for all sit-
uations in which the windshield sensors are
blocked. The driver must therefore always
keep the windshield in front of the camera/
radar sensor clean.

CAUTION

Only a workshop may perform mainte-
nance on driver support components – an
authorized Volvo workshop is recom-
mended.

Driver intervention

Backing up

City Safety is temporarily deactivated when
the vehicle is backing up.

Low speed

City Safety is not activated at very low speeds
under 4 km/h (3 mph). The system will there-
fore not intervene in situations in which your
vehicle is approaching another vehicle very
slowly, such as when parking.

Active driver

Action by the driver always has priority. City
Safety will therefore not react or will react at a
later stage with a warning or intervention in
situations in which the driver is clearly steering
and operating the accelerator pedal, even if a
collision is unavoidable.

An active and aware driving style may there-
fore delay collision warnings and intervention
in order to minimize unnecessary warnings.

Important warnings

WARNING

The driver support system only issues a

warning for obstacles detected by its radar

sensor – thus, a warning may come after a

delay or not at all.

•

Never wait for a warning or assistance.
Apply the brakes when necessary.

WARNING

•

Warnings and brake interventions can
be triggered late or not at all if the traf-
fic situation or external influences pre-
vent the camera and radar unit from
properly detecting pedestrians,
cyclists, large animals or vehicles
ahead of the vehicle.

•

To be able to detect vehicles at night,
its front and rear lights must work and
illuminate clearly.

•

The camera and radar unit have a lim-
ited range for pedestrians and cyclists
– the system can provide effective
warnings and brake interventions if the
relative speed is lower than 50 km/h
(30 mph). For stationary or slow-mov-
ing vehicles, warnings and brake inter-
ventions are effective at vehicle speeds
of up to 70 km/h (43 mph). Speed
reduction for large animals is less than
15 km/h (9 mph) and can be achieved
at vehicle speeds over 70 km/h
(43 mph). At lower speeds, the warn-
ing and brake intervention for large ani-
mals is less effective.

•

Warnings for stationary or slow-mov-
ing vehicles and large animals can be
disengaged due to darkness or poor
visibility.

•

Warnings and brake interventions for
pedestrians and cyclists are disen-
gaged at vehicle speeds over 80 km/h
(50 mph).

•

Do not place, affix or mount anything
on the inside or outside of the wind-
shield, or in front of or around the cam-
era and radar unit – this could disrupt
camera-based functions.

•

Objects, snow, ice or dirt in the area of
the camera sensor can reduce the
function, disengage it completely or
give an improper function response.

DRIVER SUPPORT

345

WARNING

•

The City Safety auto-brake function
can prevent a collision or reduce colli-
sion speed, but to ensure full brake
performance the driver should always
depress the brake pedal – even when
the car auto-brakes.

•

The warning and steering assistance
are only activated if there is a high risk
of collision – you must therefore never
wait for the collision warning or City
Safety to intervene.

•

Warnings and brake interventions for
pedestrians and cyclists are disen-
gaged at vehicle speeds over 80 km/h
(50 mph).

•

City Safety does not activate auto-
braking intervention during heavy
acceleration.

NOTE

The function uses the vehicle's camera and
radar sensor, which has certain general
limitations.

Steering assistance with braking

Intervention with steering assistance and braking

Braking intervention assists in situations
where steering assistance alone is not suffi-
cient. Braking force is automatically adapted
according to the situation at the moment the
vehicle begins to run off the road.

The function is active at speeds between
65-140 km/h (40-87 mph) on roads with
clearly visible traffic lane markings/lines.

The system uses a camera to monitor the
edges of the road and the painted side marker
lines. If the vehicle is about to cross the edge
of the road, the function will attempt to steer
the vehicle back onto the road. If this is not
sufficient to keep the vehicle on the road, the
brakes will also be applied.

However, the function will 

not

 provide either

steering assistance or braking if the turn signal

is used. The function will also not be activated
if it detects that the driver is actively operating
the vehicle.

*

Steering assistance has several sub-func-
tions. If you become distracted and do not
notice your vehicle starting to veer out of the
lane while another vehicle is approaching
from behind or is in your vehicle's blind spot,
Steering assistance during collision risks
from behind can help provide assistance.

The function provides assistance by steering your

vehicle back into your own lane.

Another vehicle in blind spot zone

Own vehicle

If your vehicle is beginning to veer out of your
lane while another vehicle is in your blind spot
or another vehicle is rapidly approaching in the

next lane, this function can help the driver
steer the vehicle back into its own lane.

Even if the driver intentionally changes lanes
using a turn signal without noticing another
vehicle approaching, the function can provide
assistance.

from vehicles approaching from behind.

The function can alert drivers of following vehi-
cles of the risk of a collision by rapidly flashing
the turn signals.

If, at a speed below 30 km/h (20 mph), the
function detects that the vehicle is in danger
of being hit from behind, the seat belt tension-
ers may tension the front seat belts. The
Whiplash Protection System will also be acti-
vated in a collision.

Immediately before a collision from behind,
the function may also activate the brakes in
order to reduce the forward acceleration of the

in the "blind spot" area behind and to the side
of the vehicle.

Location of BLIS indicator light

BLIS is a driver support system designed to
alert the driver of:

•

vehicles in your "blind spot"

•

vehicles approaching rapidly in adjacent
lanes.

BLIS overview

Blind spot zone

Rapidly approaching vehicle zone

The system is designed to react to:

•

vehicles passing your vehicle

•

vehicles that are rapidly approaching your
vehicle from behind.

When BLIS detects a vehicle in zone 1 or a
rapidly approaching vehicle in zone 2, an indi-
cator light will illuminate in the relevant rear-
view mirror and glow steadily. If the driver
then uses the turn signal on the side in which
the warning has been given, the indicator light
will become brighter and begin flashing.

BLIS is active when your vehicle is traveling at
a speed over 10 km/h (6 mph).
