Pilot Assist only functions when the driver's hands are on the steering wheel
, which is con-
tinuously monitored by the system. If this is notthe case, the driver will be alerted by a text mes-sage in the instrument panel. If the driver's handsare not returned to the steering wheel, an audiblesignal will sound. If the driver does not return his/her hands to the steering wheel after the audible signal, PilotAssist will go into standby mode and must be reactivated by pressing

WARNING
•Pilot Assist is not a collision avoidance system. The driver is always responsiblefor applying the brakes if the system doesnot detect another vehicle.
• Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in slipperyconditions, when there is a great deal ofwater or slush on the road, during heavyrain or snow, in poor visibility, on windingroads or on highway on- or off-ramps.
• Pilot Assist uses the vehicle's cameraand radar sensor, which have limitations.
Pilot Assist may deactivate or not function optimally if:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• if there are edges or other lines on ornear the lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations:
• High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override Pilot Assist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills, when thevehicle is transporting a heavy load or if it is tow-ing a trailer. The driver should be attentive andprepared to apply the brakes in these situations.

appears, the ACC radar sensor is blocked and cannot detect vehicles ahead.
This message also indicates that the following systems may have reduced functionality:
• Distance Alert
• City Safety
• Driver Alert Control
• Pilot Assist
• Lane Departure Warning (LDW) •
Lane Keeping Aid (LKA)
• Traffic Sign Information (TSI)
The following table lists possible causes for thismessage being displayed and suitable actions:
CauseAction
The windshield in front of the radar is dirty or covered with snow/ice.Clean/clear the windshield in front of the radar.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the radar.
Swirling water or snow from the surface of the road may interfere with the radar signals.No action possible. A very wet or snow-covered road surface may affect the function of the radar.
The windshield in front of the radar is clean but the message remains in the display.Wait a short time. It may take several minutes for the radar to detect that it is no longer obstructed.
A text message can be erased by briefly pressing the O button on the right-side steering wheel
keypad. If the message recurs, contact a trained and authorized Volvo service technician orretailer.

Camera and radar sensor's field of vision
The camera and radar sensor have limited fields of vision. In some situations they may detect avehicle, pedestrian or cyclist later than expectedor not detect them at all. Other vehicles that are dirty may be detected later than others and in dark conditions, motorcy-cles may be detected late or not at all. If a text message is displayed in the instrument panel indicates that the camera or radar sensorare blocked, it may be difficult for City Safety todetect a vehicle, pedestrian or cyclist and thesystem's functionality may be reduced.
WARNING
Text messages may not be displayed in all sit- uations in which the camera and/or radarsensor are blocked. It is therefore essential tokeep the windshield in front the camera/radarsensor clean and free from snow, ice, etc.
Camera and radar sensor components should only be serviced or replaced by a trained andqualified Volvo service technician.
Other limitations
City Safety uses the vehicle's camera and radar sensor, which have certain general limitations.See the articles "Camera limitations" and Radarsensor limitations" for additional information.
WARNING
• Warnings and braking may be delayed or not occur at all if traffic, weather or otherconditions prevent the camera and/orradar sensor from detecting pedestrians,cyclists or other vehicles correctly.
• Other vehicles can only be detected indarkness if their headlights and taillightsare clearly visible.
• The sensors have a limited range forpedestrians and cyclists. The systemfunctions best at speeds up to 30 mph(50 km/h). For stationary or slow-movingvehicles, the system functions best atspeeds up to approx. 43 mph (70 km/h).
• Warnings for stationary or slow-movingvehicles may be impeded by darkness orpoor visibility.
• Warnings and braking for pedestrians andcyclists will not be provided at speedsabove approx. 50 mph (80 km/h).
• Do not place, attach or mount any objectson the inside or outside of the windshieldnear or over the sensor. This could affectthe camera-based functions.
Action by the driver
Backing up
City Safety is temporarily deactivated while the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds (under approx. 3 mph (4 km/h). This means thatthe system will not be triggered if your vehicleapproaches a vehicle ahead, such as when park-ing.
Active driver
Action by the driver always has priority. For this reason, City Safety may not react or react laterthan expected in situations in which the driver isactively operating the vehicle, even if a collision isimminent. This is also done to help eliminateexcessive warnings.

City Safety™ troubleshooting
Messages pertaining to any possible problems with City Safety will be displayed in the instru-ment panel.
Troubleshooting and remedial action
Location of the camera and the radar sensor
If a message is displayed in the instrument panel saying that the camera/radar sensor is blocked,
City Safety cannot detect vehicles, cyclists orpedestrians ahead of you, which means that thesystem is not functioning properly. However, this message will not be displayed in all situations in which the camera/radar sensor isobstructed. For this reason, the driver mustensure that the area of the windshield in front ofthe camera/radar sensor is always kept clean. The following table shows some of the situationsthat can cause the message to be displayed andsuggested actions.
CauseAction
The area of the wind- shield in front of thecamera/radar sensor isdirty or covered by ice orsnow.Clean the wind- shield or removethe ice/ snow.
Thick fog or heavy rain/ snow blocks reduces thecamera/radar sensor'srange of visibility.No action. The driver should beextra alert in condi-tions of this type.
There is dirt between the inside of the wind-shield and the camera/radar sensor.Have the area of the windshieldcleaned by atrained and quali-fied Volvo servicetechnician.
CAUTION
•
Service and maintenance on City Safety may only be carried out by a trained andqualified Volvo service technician.
• If a crack, scratch or stone chip shouldoccur in the section of the windshield infront the camera/radar sensor, contact atrained and qualified Volvo service techni-cian to repair or replace the windshield.Failing to do so may result in reducedCity Safety functionality.
To help prevent limited or reduced functional- ity, please also observe the following:
• Volvo recommends that cracks, scratches or stone chips on the windshield in front of the camera/radar sensor should
not
be repaired; in such cases, the entire windshield should be replaced.
• Before the windshield is replaced, con-tact a Volvo retailer to ensure that thecorrect windshield is ordered and instal-led. If the wrong type of windshield isused, this may cause City Safety to func-tion improperly or not at all.
• Volvo recommends the use of only Genu-ine Volvo Replacement Windshields.
• When replacing windshield wipers, usethe same type or ones approved by Volvo.

After the windshield has been replaced, the camera/radar sensor will have to be recalibra-ted by a trained and qualified Volvo servicetechnician to help ensure proper function ofall of the vehicle's camera-/radar-based sys-tems.
MaintenanceIn order for City Safety to function properly, the area of the windshield must be kept free of dirt,ice, snow, etc.
Other vehicle functionsIf a message is displayed in the instrument panel,this means that the other systems using the cam-era/radar sensor (see the list below) will not havefull functionality or may not function at all. The radar sensor is used by the following func- tions:
• Distance Alert
*
• Driver Alert Control
*
• Adaptive Cruise Control
*
• Pilot Assist
*
• Road Sign Information
*
• Active High Beams
*
• Lane Keeping Aid
*
Do not mount or in any way attach anything onthe windshield that could obstruct the camera/radar sensor.
WARNING
• The camera has the same type of limita- tions as the human eye, i.e., it cannot seeas well in heavy snowfall or rain, thick fogor in heavy blowing dust or snow. In suchconditions, systems depending on thecamera may experience greatly reducedfunctionality or may be temporarily deacti-vated.
• Never place any objects, decals, etc., onthe windshield in front of the camera. Thiscould reduce or block the camera
