Manual operation
NOTE
Keep the windscreen surface in front of the camera sensor free from ice, snow, mist anddirt. Do not stick or attach anything to the wind- screen in front of the camera sensor as thismay reduce effectiveness or cause one ormore of the systems dependent on the cam-era to stop working.
If this symbol is shown in the driver dis- play, together with the message Active
High Beam Temporarily
unavailable, then switching between
main and dipped beam must be performed man- ually. The rotating ring on the stalk switch can still be in the
position. The symbol extin-
guishes when these message are shown.
The same applies if this symbol is shown together with the message
Windscreen sensor Sensor
blocked, see Owner's manual.
Active main beam may be temporarily unavailable e.g. in situations with dense fog or heavy rain.When active main beam becomes available again,or the windscreen sensors are no longer blocked, the message goes out and the
symbol illu-
minates.
WARNING
Active main beam is an aid for using the opti- mum beam pattern when conditions arefavourable. The driver always bears responsibility for man- ually switching between main and dippedbeam when traffic situations or weather con-ditions so require.
IMPORTANT
Examples of when manual switching between main and dipped beam may be required:
• In heavy rain or dense fog
• In freezing rain
• In snow flurries or slush
• In moonlight
• When driving in poorly lit built-up areas
• When the traffic ahead has weak lighting
• If there are pedestrians on or beside theroad
• If there are highly reflective objects suchas signs in the vicinity of the road
• When the lighting from oncoming trafficis obscured by e.g. a crash barrier
• When there is traffic on connecting roads
• On the brow of a hill or in a hollow
• In sharp bends.

Active bending lights *
Active bending lights are designed to provide maximum illumination in bends and junctions. Cars with LED 26
headlamps * can have active
bending lights, depending on the car's equip- ment level.
Headlamp pattern with function deactivated (left) and activated (right) respectively.
The LED headlamps can include the Active bend- ing lights function, depending on the car's equip-ment level. Active bending lights follow steeringwheel movements to provide maximum illumina-tion in bends and junctions and thereby increasesafety. The function is activated automatically when the car is started. In the event of a fault in the func- tion, the
symbol illuminates in the driver
display at the same time as the driver display shows an explanatory text. The function is only active in weak daylight or darkness and only when the car is moving anddipped beam is switched on.

* Option/accessory.315
IMPORTANT
In certain situations, Pilot Assist steering assistance may have difficulty helping thedriver in the right way or it may be automati-cally deactivated - in which case, the use ofPilot Assist is not recommended. Examples ofsuch situations may be that: •the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits or inthe event of multiple sets of markings.
• edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong 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 impaired viewwith poor light conditions, back-lighting,wet road surface etc.
The driver should also note that Pilot Assisthas the following limitations: • High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane
markings, with a subsequent risk of con- tact between the car and such obstacles.The driver must ensure him/herself thatthe car is at a suitable distance from suchobstacles.
• The camera and radar sensor does nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects which completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is forcelimited, which means that it cannotalways help the driver to steer and keepthe car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed byPilot Assist and can turn the steering wheel tothe desired position.
Steep roads and/or heavy loadBear in mind that Pilot Assist is primarilyintended for use when driving on level road surfa-ces. The function may have difficulty in keepingthe correct distance from the vehicle ahead whendriving on steep downhill slopes - in which case,be extra attentive and ready to brake. Do not usePilot Assist with a heavy load or with a trailer con-nected to the car.
Miscellaneous
•Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Limitations of the camera unit
The camera unit has certain limitations - which in turn also limits those functions that use the unit.
Impaired visionThe camera has limitations similar to the human eye, i.e. it can "see" worse in for example intensesnowfall or rain, dense fog, heavy dust stormsand snow flurries. Under such conditions, thefunctions of camera-dependent systems could besignificantly reduced or temporarily disengaged. Strong oncoming light, reflections in the carriage- way, snow or ice on the road surface, dirty roadsurfaces or unclear lane markings can also sig-nificantly reduce camera function when it is usedto scan the carriageway to detect pedestrians,cyclists, large animals and other vehicles.
Blocked unit
The marked area must be kept free from stickers, objects, shade film, etc. 13
.
The camera unit is placed inside the upper sec- tion of the windscreen together with the car'sradar unit.
IMPORTANT
Do not place, stick or mount anything on the outside or inside of the windscreen in front ofor around the camera and radar unit — thiscan interfere with camera and radar-depend-ent functions. This may mean that functions are reduced, deactivated completely or give incorrect func-tion response.
If the driver display shows this symbol with the message Windscreen
sensor Sensor blocked, see
Owner's manual, it means that the
camera and radar unit cannot detect other vehi- cles in front of the car.
The following table presents examples of possi- ble causes for a message being shown, alongwith the appropriate action:

CauseAction
The windscreen surface in front of the camera and radar unit is dirty or covered with ice or snow. Clean dirt, ice and snow from the windscreen surface in front of the camera andradar unit.
Thick fog and heavy rain or snow block the radar signals or the cameraview. No action. Sometimes the unit does not work during heavy rain or snowfall.
Water or snow from the road surface swirls up and blocks the radarsignals or camera view. No action. Sometimes the unit does not work on a very wet or snow-covered roadsurface.
Dirt has appeared between the inside of the windscreen and the cam-era and radar unit. Visit a workshop to have the windscreen inside the unit's cover cleaned - anauthorised Volvo workshop is recommended.
Strong oncoming light No action. The camera unit is reset automatically in more favourable light condi-tions.
NOTE
Keep the windscreen clean in front of the camera and radar unit.
High temperatureAt very high temperatures the camera and radar unit can temporarily be switched off forabout 15 minutes after the engine is started soas to protect the unit's electronics. The cameraand radar unit restarts automatically when thetemperature has fallen sufficiently.
Damaged windscreen
IMPORTANT
If a crack, scratch or stone chip in the wind- screen in front of one of the camera andradar unit “windows” covers an area ofapprox. 0.5 x 3.0 mm or larger, a workshopmust be contacted to have the windscreenreplaced. An authorised Volvo workshop isrecommended. If not rectified it can lead to reduced perform- ance for the driver support systems that usethe camera and radar unit.
This may mean that functions are reduced, deactivated completely or give incorrect func-tion response. To avoid the risk of failed, deficient or reduced operation of driver support systemsthat use the radar unit, the following alsoapplies:
• Volvo recommends
against repairing
cracks, scratches or stone chips in thearea in front of the camera and radar unit.Instead, the whole windscreen should bereplaced.
• Before replacing a windscreen, contactan authorised Volvo workshop to verify
