WARNING
The function is supplementary driver sup-port intended to facilitate driving and helpmake it safer – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion.
Driver support functions are not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.
Pilot Assist regulates speed by accelerating andbraking. It is normal for the brakes to emit a slightsound when they are being used to adjust speed.
Pilot Assist attempts to smoothly regulate speed.The driver must apply the brakes in situationsrequiring immediate braking. For example, whenthere are great differences in speed betweenvehicles or if the vehicle ahead brakes suddenly.
Due to limitations in the camera and radar sen-sor, braking may occur unexpectedly or not at all.
Pilot Assist is designed to follow a vehicle aheadin the same lane and maintain a time interval tothat vehicle set by the driver. If the radar sensordoes not detect a vehicle ahead, it will insteadmaintain the speed set by the driver. This will alsohappen if the speed of the vehicle aheadexceeds the set speed for your vehicle.

WARNING
This is not a collision avoidance system.The driver is always responsible and mustintervene if the system fails to detect avehicle ahead.
The function does not brake for people oranimals and does not brake for smallvehicles, such as bikes and motorcycles.Similarly, it does not brake for low trailers,oncoming, slow-moving or stationary vehi-cles and objects.
Do not use the function in demanding sit-uations, such as in city traffic, at intersec-tions, on slippery surfaces, with a lot ofwater or slush on the road, in heavy rain/snow, in poor visibility, on winding roads,or on on/off ramps.
CAUTION
Maintenance of driver support components
may only performed by a workshop31.

In curves and forks in the road
Pilot Assist is designed to interact with the driver.The driver should never wait for steering assis-tance from Pilot Assist, but instead should alwaysbe ready to increase his or her own steeringefforts, particularly in curves.
When the vehicle is approaching an off-rampor a fork in the road, the driver should steertoward the desired lane to indicate to PilotAssist the desired direction of travel.

Pilot Assist strives to keep the vehicle
in the center of the lane
When Pilot Assist provides steering assistance, itstrives to position the vehicle in the center of thelane between the lane markings. For the smooth-est driving experience possible, the driver shouldpermit the vehicle to find the optimal positioning.The driver should check that the vehicle is posi-tioned safely in the lane and can always adjustthe vehicle's position by applying more force tothe steering wheel.
If Pilot Assist does not position the vehicleappropriately in the lane, the driver should

Standby mode due to action by the driver
Pilot Assist will be temporarily deactivated andput in standby mode if:
the brakes are applied.
the gear selector is moved to N.
a turn signal is used for more than 1 minute.
the vehicle is driven faster than the setspeed for more than 1 minute.
Temporarily increasing speed using the accelera-tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
When the turn signals are used, Pilot Assist'ssteering assistance will be temporarily deacti-vated. When the turn signal is switched off, steer-ing assistance will be automatically reactivated ifthe traffic lane's side markings can still bedetected.

Automatic standby mode
Pilot Assist is dependent on other systems, such
as Electronic Stability Control (ESC32). If any ofthese other systems stops working, Pilot Assistwill automatically switch off.
WARNING
With automatic standby mode, the driver iswarned by an acoustic signal and a messageon the instrument panel.
The driver must then regulate vehiclespeed, apply the brakes if necessary, andmaintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standbymode if, e.g.:
the driver opens the door.
the brake temperature is high.
the driver's hands are not on the steeringwheel.
the parking brake is applied.
the engine speed (rpm) is too low/high.
the driver unbuckles the seat belt.
one or more of the wheels lose traction.
the camera/radar sensor is covered by snowor heavy rain (the camera lens/radar wavesare blocked).
your vehicle's speed goes under 5 km/h(3 mph) and Pilot Assist cannot determine ifthe vehicle ahead is stationary or if it isanother object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatPilot Assist no longer has a vehicle to follow.

Reactivating Pilot Assist from standby
mode
Note: This illustration is general and details may varydepending on model.
To reactivate Pilot Assist:
–Press the button on the steering wheel(1).
>Speed will be set to the most recentlystored speed.

DRIVER SUPPORT
* Option/accessory.288
The driver is responsible for ensuring thatthe vehicle maintains a suitable distancefrom such obstacles.
The camera and radar sensors do nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects that completely or partiallyblock the route.
Pilot Assist does not "see" pedestrians,animals, etc.
The recommended steering input is lim-ited in force, which means that it cannotalways help the driver to steer and keepthe vehicle within the lane.
In vehicles equipped with SensusNavigation*, the function is able to useinformation from map data, which couldcause variations in performance.
Pilot Assist will be switched off if thespeed-dependent power steering wheelresistance is working at reduced power,e.g. during cooling due to overheating.
The driver can always correct or adjust steeringassistance provided by Pilot Assist by turning thesteering wheel to the desired position.

Steep roads and/or heavy loads
Pilot Assist is primarily intended to be driven onflat roads. The function may not be able to main-
tain the correct time interval to the vehicle aheadwhen driving down steep hills. The driver shouldbe extra attentive and prepared to apply thebrakes.
Do not use Pilot Assist if the vehicle is carry-ing a heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer,bike carrier or similar is connected to thevehicle electrical system.

Other limitations
The Off Road drive mode cannot beselected when Pilot Assist is activated.

NOTE
The function uses the vehicle's camera andradar sensor, which has certain general limita-tions.

Camera/radar sensor distance monitoring
Driver support uses approx. 40% of the vehicle'sbraking capacity. If a situation requires morebraking force than driver support can provide, andif the driver does not apply the brakes, a warning
light and audible warning signal will be activatedto alert the driver that immediate action isrequired.
WARNING
The driver support system only issues a warn-ing for vehicles detected by its radar unit –thus, a warning may come after a delay or notat all. Never wait for a warning. Apply thebrakes when necessary.

Camera/radar sensor limitations
The camera and radar sensor used by several ofthe driver support functions has certain limita-tions, which also affect the functions using thecamera and radar sensor. The driver should beaware of the following limitations:

Camera and radar
Obstructed camera
The area marked in the illustration must be cleaned reg-ularly and kept free of decals, objects, solar film, etc.
The camera is located on the upper interior sec-tion of the windshield along with the radar sen-sor.
Do not place, affix or mount anything on theinside or outside of the windshield, or in front ofor around the camera and radar sensor – thiscould disrupt camera and radar-based functions.It could cause functions to be reduced, deacti-vated completely or to produce an incorrect func-tion response.
If this symbol and the message“Windscreen sensor Sensorblocked, see Owner's manual” isdisplayed in the instrument panel, itmeans that the camera and radar sensor areunable to detect other vehicles, cyclists, pedes-trians and large animals in front of the vehicleand that the vehicle's camera and radar-basedfunctions may be obstructed, reduced, completelydisabled or providing inaccurate responses.
The following table shows some of the situationsthat can cause the message to be displayed, andsuggested actions:
CauseAction
The area of the windshield in front of the camera/radar sensor isdirty or covered by ice or snow.Clean the windshield in front of the camera/radar sensor and remove dirt, ice andsnow.
Thick fog, heavy rain or snow is blocking the radar signals or thecamera's range of visibility.No action. Heavy precipitation may sometimes prevent the camera/radar sensor fromfunctioning.

DRIVER SUPPORT

301
CauseAction
Water or snow is spraying/swirling up and blocking the radar signalsor the camera's range of visibility.No action. Very wet or snow-covered roads may sometimes prevent the camera/radar sensor from functioning.
There is dirt between the inside of the windshield and the camera/radar sensor.Consult a workshop to have the area of the windshield on the inside of the camera'scasing cleaned. An authorized Volvo workshop is recommended.
Bright sunlight.No action. The camera/radar sensor will reset automatically when lighting conditionsimprove.

High temperatures
If the temperature in the passenger compartmentis very high, the camera/radar sensor will switchoff temporarily for approx. 15 minutes after theengine is started to protect its electronic compo-nents. When the temperature has cooled suffi-ciently, the camera/radar sensor will automati-cally restart.

Damaged windshield
NOTE
Failure to take action could result in reducedperformance for the driver support systemsthat use the camera and radar unit. It couldcause functions to be reduced, deactivatedcompletely or to produce an incorrect func-tion response.
To avoid the risk of loss of function, malfunctionor reduced function of the driver support systemsthat use the radar sensor, the following alsoapply:
If there are cracks, scratches or stone chipson the windshield in front of any of the cam-era and radar sensor "windows" and this cov-ers an area of about 0.5 × 3.0 mm(0.02 × 0.12 in.) or more, contact a workshop
to have the windshield replaced45.
Volvo advises against repairing cracks,scratches or stone chips in the area in frontof the camera and radar sensor – the entirewindshield should instead be replaced.
Before replacing the windshield, contact a
workshop45 to verify that the right windshieldhas been ordered and installed.
The same type of windshield wipers or wip-ers approved by Volvo should be used forreplacement.
If the windshield is replaced, the camera andradar sensor must be recalibrated by a work-
shop45 to help ensure proper functioning ofall of the vehicle's camera and radar-basedsystems.
Radar
Vehicle speed
The radar sensor's ability to detect a vehicleahead is significantly reduced if the speed of thevehicle ahead differs greatly from your vehicle'sspeed.

Limited field of vision
The radar sensor has a limited field of vision. Insome situations, it may detect a vehicle later thanexpected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles veryclose to your vehicle may be delayed in cer-tain situations, e.g. if a vehicle pulls in
between your vehicle and the vehicle directlyahead.
Small vehicles, such as motorcycles, or vehi-cles that are not driving in the center of thelane may remain undetected.
In curves, the radar may detect the wrongvehicle or lose sight of a target vehicle.

Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossi-ble for the radar to detect. The driver should beextra alert when driving behind vehicles towinglow trailers when Adaptive Cruise Control or PilotAssist is activated.

Camera
Reduced visibility
Cameras have the same limitations as the humaneye. In other words, their “vision" is impaired byadverse weather conditions such as heavy snow-fall/rain, dense fog, swirling dust/snow, etc.These conditions may reduce the function of sys-
tems that depend on the camera or cause thesesystems to temporarily stop functioning.
Strong sunlight, reflections from the road surface,ice or snow covering the road, a dirty road sur-face, or unclear lane marker lines may drasticallyreduce the camera
