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 is
used, 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 camera and radar sensor to function properly, the area of the windshield must be keptfree of dirt, ice, snow, etc. and should be washedregularly with a suitable car washing detergent.

Radar sensor limitations
The radar sensor used by several of the driver support systems has certain limitations, whichalso affect the systems using it.
Obstructions
The marked area must not be obstructed in any way. This area of the windshield should always be kept clean
The radar sensor is located at the upper, center section of the windshield along with the camera.
WARNING
Never place any objects, decals, etc., on the windshield in front of the camera/radar unit.This could reduce or block these components'functions, and could cause one or more of thesystems that utilize the them to stop function-ing.
If this symbol and
Windscreen
sensor Sensor blocked, see
Owner's manual appear in the instru-
ment panel, this indicates that the
camera and/or radar sensor cannot detect other vehicles ahead.
The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
CauseAction
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow.Clean the windshield or remove the ice/ snow.
Thick fog or heavy rain/snow blocks reduces the camera/radar sensor's range of visibility.No action. The driver should be extra alert in conditions of this type.

There is dirt between the inside of the windshield and the camera/radar sensor.Have the area of the windshield cleaned by a trained and quali- fied Volvo service technician.
The radar sensor's capacity to detect vehicles ahead is impeded:
• if the speed of the vehicle ahead differs greatly from your vehicle's speed.
Limited field of visionThe radar sensor has a limited field of vision. In some situations it may detect a vehicle later thanexpected or not detect other vehicles at all.
Radar sensor's field of vision
In certain situations, the radar sensor cannot detect vehicles at close quarters, for example a vehicle that suddenly enters the lanebetween your vehicle and the target vehicle.
Small vehicles, such as motorcycles, or vehi- cles not driving in the center of the lane mayremain undetected.
In curves, the radar sensor may detect the wrong vehicle or lose sight of the target vehi-cle.
Low trailer in the radar shadow
Low trailers may also be difficult to detect or may not be detected at all. The driver should be extraalert in situations of this type.

• 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.
Hands on the steering wheelPilot 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

HeatIf the temperature in the passenger compartment is very high, the camera and radar sensor may betemporarily turned off for approx. 15 minutesafter the engine has been started to protect theirelectronic components. When the temperaturehas cooled sufficiently, the camera and radarsensor will restart automatically. The visual warning signal may also be temporarily disabled due to high passenger compartmenttemperatures caused by strong sunlight. Warnings may not be given if the distance to the vehicle ahead is short and the driver is activelyoperating the vehicle (clearly depressing a pedalor turning the steering wheel).
Reduced visibilityCity Safety's functions may be greatly impeded or deactivated by e.g., intense snowfall or rain, indense fog, in very dusty conditions or if there isblowing snow in front of the vehicle. Condensa-tion, ice, snow or dirt on the windshield may alsoreduce the system's functionality.
NOTE
•Keep the windshield in front of the radar sensor free of ice, snow, dirt, etc.
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sensor.Keep the hood free of ice and snow.
• Do not mount or in any way attach any-thing on the windshield that couldobstruct the radar sensor.
Camera and radar sensor's field of visionThe 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. Camera and radar sensor components should only be serviced or replaced by a trained andqualified Volvo service technician.
Other limitations
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 upCity Safety is temporarily deactivated while the vehicle is backing up.
Low speedCity 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 driverAction 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.
