DRIVER SUPPORT
* Option/accessory.
278 Driver support systems
The vehicle is equipped with a number of driver
support systems that can provide the driver with
active or passive assistance in various situations.
The systems can, for example, help the driver:
maintain a set speed
maintain a set time interval to the vehicle
ahead
help prevent a collision by warning the driver
and applying the brakes
park the vehicle.
Some of the systems are standard and others are
options. This also varies from market to market.

resistance
Speed-dependent power steering increases the
steering wheel resistance in pace with the vehi-
cle's speed to give the driver an enhanced feel-
ing of control and stability.
Steering may feel stiffer on highways. When
parking and at low speeds, it will be easier to
move the steering wheel.
NOTE In some situations, the power steering may
become too hot and require temporary cool-
ing – during such time the power steering will
work at reduced output and the steering
wheel may feel more difficult to move.
In parallel with the temporarily reduced steer-
ing assistance, the driver display shows a
message as well as a STEERING WHEEL
symbol.
WARNING
While the power steering is working at
reduced power, the driver support functions
and systems with steering assistance are not
available.
In such a situation, the driver display shows
the
Power steering failure message, com-
bined with a STEERING WHEEL symbol.

Pilot Assist limitations
Pilot Assist functionality may be reduced in cer-
tain situations.
Pilot Assist is a driver support function designed
to simplify driving and assist the driver in many
situations. However, the driver is always responsi-
ble for maintaining a suitable distance to vehicles
or objects around it and ensuring that the vehicle
is correctly positioned in the traffic lane.
WARNING In some situations, Pilot Assist may have trou-
ble helping the driver properly or may be
deactivated automatically – we advise against
using Pilot Assist in such cases. Examples of
such situations include:
the lane markings are worn, missing or
cross each other.
lane division is unclear, for example, when
the lanes divide or merge or at exits or
when there are multiple sets of markings.
edges or other lines than lane markings
are present on or near the road, e.g.
curbs, joints or repairs to the road sur-
face, edges of barriers, roadside edges or
strong shadows.
the lane is narrow or winding.
the lane contains ridges or holes.
weather conditions are poor, e.g. rain,
snow or fog or slush or reduced visibility
with poor light conditions, backlighting,
wet road surface, etc.
The driver should also note that Pilot Assist
has the following limitations:
High curbs, roadside barriers, temporary
obstacles (traffic cones, safety barriers,
etc.) are not detected. Alternatively, they
may be detected incorrectly as lane mark-
ings, with a subsequent risk of contact
between the vehicle and such obstacles. The driver is responsible for ensuring that
the vehicle maintains a suitable distance
from such obstacles.
The camera and radar sensors do not
have the capacity to detect all oncoming
objects and obstacles in traffic environ-
ments, e.g. potholes, stationary obstacles
or objects that completely or partially
block the route.
Pilot Assist does not "see" pedestrians,
animals, etc.
The recommended steering input is lim-
ited in force, which means that it cannot
always help the driver to steer and keep
the vehicle within the lane.
In vehicles equipped with Sensus
Navigation*, the function is able to use
information from map data, which could
cause variations in performance.
Pilot Assist is switched off if the power
steering is working with reduced power -
e.g. during cooling due to overheating
(see section "Speed-dependent steering
force").
The driver can always correct or adjust steering
assistance provided by Pilot Assist by turning the
steering wheel to the desired position.

City Safety limitations
City Safety functionality may be reduced in cer-
tain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhanging
loads or accessories such as auxiliary lights or
front protective grids that extend beyond the
height of the hood, may limit City Safety function-
ality.
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 situations, the Anti-
lock Braking System and Electronic Stability Con-
trol (ESC 73
) will help provide 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 compartment
is high due to e.g. bright sunlight, the visual warn-
ing 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 cer-
tain situations, it may be unable to detect pedes-
trians, 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, motorcy-
cles may be detected late or not at all.
If a text message displayed in the instrument
panel indicates that the camera/radar sensor is
obstructed, it may be difficult for City Safety to
detect pedestrians, large animals, cyclists, vehi-
cles or lane markings in front of the vehicle. City
Safety functionality may therefore be reduced.
Text messages may not be displayed for all situa-
tions in which the windshield sensors are
blocked. The driver must therefore always keep
the windshield in front of the camera/radar sen-
sor clean.
CAUTION Maintenance and replacement of City Safety
components may only be performed by a
workshop – an authorized Volvo workshop is
recommended.
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 therefore
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 situa-
tions 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 therefore
delay collision warnings and intervention in order
to minimize unnecessary warnings.

376Lane Keeping Aid limitations
In certain demanding driving conditions, Lane
Keeping Aid may not be able to properly assist
the driver. In these situations, it is recommended
that the function be deactivated.
Examples of such situations include:
road work
winter driving conditions
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane's
side markings
when the power steering works at reduced
power, e.g. during cooling due to overheating
(see section “Speed-dependent steering
force”).
NOTE The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

Limitations of Run-Off Mitigation
with steering assistance
In certain demanding driving conditions, the
function may not be able to properly assist the
driver. In these situations, it is recommended
that it is turned off.
Examples of such situations include:
road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane's
side markings
when the power steering works at reduced
power, e.g. during cooling due to overheating
(see section “Speed-dependent steering
force”).
NOTE The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

risks from oncoming traffic
This sub-function can help assist a distracted
driver who has not noticed that the vehicle is
veering into oncoming traffic. The function provides assistance by swerving your vehi-
cle back into your own lane.
Oncoming vehicles
Own vehicle
The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly
visible traffic lane markings/lines.
If your vehicle is starting to veer from your own
lane and a vehicle is approaching from the oppo-
site direction, this function can help the driver
steer the vehicle back into its own lane.
