Radar sensor limitations
The radar sensor used by several of the driversupport 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, centersection of the windshield along with the camera.
WARNING
Never place any objects, decals, electronic tolldevices, window tinting films etc., on the wind-shield in front of or around the camera/radarsensor. This could reduce or block these com-ponents' functions, and could cause one ormore of the systems that utilize them to stopfunctioning.
This can also result in certain functions beingreduced or disabled, or they may respondincorrectly.
If this symbol and the messageWindscreen Sensors blockedappear in the instrument panel, thisindicates that the camera and/or radarsensor cannot detect other vehicles ahead.
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 is dirty or covered by iceor snow.Clean the windshield or remove the ice/ snow.
Thick fog or heavy rain/snow reduces the camera/radar sensor's range of visibility.No action. The driver should be extra alert in conditions of thistype.
Water or snow on the surface of the road swirl up and block radar signals or the camera'sview.No action. The driver should be extra alert in conditions of thistype.
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.

Vehicle's speed
The radar sensor's capacity to detect vehiclesahead is impeded:
•if the speed of the vehicle ahead differsgreatly from your vehicle's speed.

Limited field of vision
The radar sensor has a limited field of vision. Insome 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 cannotdetect vehicles at close quarters, for examplea 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 thewrong vehicle or lose sight of the target vehi-cle.
Low trailer in the radar shadow (generic illustration)
Low trailers may also be difficult to detect or maynot be detected at all. The driver should be extraalert in situations of this type.

High temperatures
If the temperature in the passenger compartmentis 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.

CAUTION
•Service and maintenance on City Safetymay 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.
•This can also result in certain functionsbeing reduced or disabled, or they mayrespond incorrectly.
To help avoid the risk of incorrect, reduced ordisabled functionality for driver support sys-tems using the camera or radar sensors:
•Volvo recommends that cracks, scratchesor stone chips on the windshield in frontof the camera/radar sensor should notbe repaired; in such cases, the entirewindshield 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, thecamera/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.

Maintenance
In order for camera and radar sensor to functionproperly, the area of the windshield must be keptfree of dirt, ice, snow, etc. and should be washedregularly with a suitable car washing detergent.

NOTE
Dirt, ice and/or snow covering the cameraand radar sensors reduce functionality andmay disable the vehicle's camera-/radar-based systems.
This can also result in certain functions beingreduced or disabled, or they may respondincorrectly.

Camera limitations
The camera used by several of the driver supportsystems has certain limitations, which also affectthe systems using it.

Reduced visibility
WARNING
•The camera has the same limitations asthe human eye. In other words, its “visionis impaired” by adverse weather condi-tions such as heavy snowfall, dense fog,etc. These conditions may reduce thefunction of systems that depend on thecamera or cause these systems to tem-porarily stop functioning.
•Strong sunlight, reflections from the roadsurface, ice or snow covering the road, adirty road surface, or unclear lane markerlines may drastically reduce the camera

City Safety™
City Safety™ is a support system designed tohelp alert the driver to pedestrians, cyclists, largeanimals and vehicles that may appear suddenlyin front of your vehicle by providing visual, audi-ble and haptic alerts. The vehicle will brake auto-matically if the driver is unable to react quicklyenough.

City Safety introduction
Location of the camera and radar sensor (generic illus-tration)
City Safety can help prevent a collision or lowerthe vehicle's speed at the point of impact.
WARNING
•City Safety™ is a supplemental aid to thedriver. It can never replace the driver
