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.

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

ASL symbolA road sign symbol (next to the stored speed in the center of the speedome-ter) can be displayed in three differentcolors as explained in the following
table:
Road sign sym-
bol's colorExplanation
Green/yellowASL is active
GrayASL is in standby mode
Amber/orangeASL is temporarily in standby mode (e.g., becausea speed limit sign could notbe read)
LimitationsAdjusting a set speed is done first when the vehi- cle passes a speed limit sign. If a speed limit signcannot be read (e.g., because it is twisted, dam-aged, faded, dirty, covered by snow, etc.) ASL willgo into standby mode because the system willnot have "seen" the speed posted on the sign(SL will activate). The driver will have to react andadapt the vehicle's speed. ASL will reactivatewhen the vehicle passes a speed limit sign thatthe system can read.
