Limitations of the radar unit The radar unit has certain limitations - which in turn also limits those functions that use the unit.
Blocked unit
The marked area must be kept free from stickers, objects, shade film, etc.12
.
The radar unit is placed inside the upper section of the windscreen together with the car's cameraunit.
IMPORTANT
Do not place, stick or mount anything on the outside or inside of the windscreen in front ofor around the camera and radar unit — thiscan interfere with camera and radar-depend-ent functions. This may mean that functions are reduced, deactivated completely or give incorrect func-tion response.
If the driver display shows this symbol with the message Windscreen
sensor Sensor blocked, see
Owner's manual, it means that the
camera and radar unit cannot detect other vehi- cles in front of the car.
The following table presents examples of possi- ble causes for a message being shown, alongwith the appropriate action:
Cause Action
The windscreen surface in front of the camera and radar unit is dirty or cov- ered with ice or snow. Clean dirt, ice and snow from the windscreen surface in front of the cameraand radar unit.
Thick fog and heavy rain or snow block the radar signals or the cameraview. No action. Sometimes the unit does not work during heavy rain or snowfall.

CauseAction
Water or snow from the road surface swirls up and blocks the radar signals or camera view. No action. Sometimes the unit does not work on a very wet or snow-coveredroad surface.
Dirt has appeared between the inside of the windscreen and the cameraand radar unit. Visit a workshop to have the windscreen inside the unit's cover cleaned - anauthorised Volvo workshop is recommended.
NOTE
Keep the windscreen clean in front of the camera and radar unit.
Vehicle speedThe capacity of the radar unit to detect vehicles ahead is reduced significantly if:
• the speed of the vehicle ahead is signifi-cantly different from that of your own car
Limited field of visionThe radar unit has a limited field of vision. Insome situations another vehicle is not detected,or the detection is made later than expected.
The radar unit's field of vision.
Sometimes the radar unit is late at detecting vehicles at close distances - e.g. a vehicle that drives in between your car and the vehi-cle ahead.
Small vehicles, such as motorcycles, or vehi- cles not driving in the centre of the lane canremain undetected.
In bends, the radar unit may detect the wrong vehicle or lose a detected vehicle fromview.
Low trailers
Low trailer in radar shadow.
Low trailers can also be difficult for the radar unit to detect, or are not detected at all - the drivershould therefore be particularly careful when driv-ing behind low trailers when the adaptive cruisecontrol or Pilot Assist is activated.

High temperatureAt very high temperatures the camera and radar unit can temporarily be switched off forabout 15 minutes after the engine is started soas to protect the unit's electronics. The cameraand radar unit restarts automatically when thetemperature has fallen sufficiently.
Damaged windscreen
IMPORTANT
If a crack, scratch or stone chip in the wind- screen in front of one of the camera andradar unit “windows” covers an area ofapprox. 0.5 x 3.0 mm or larger, a workshopmust be contacted to have the windscreenreplaced. An authorised Volvo workshop isrecommended. If not rectified it can lead to reduced perform- ance for the driver support systems that usethe camera and radar unit. This may mean that functions are reduced, deactivated completely or give incorrect func-tion response. To avoid the risk of failed, deficient or reduced operation of driver support systemsthat use the radar unit, the following alsoapplies:
• Volvo recommends
against repairing
cracks, scratches or stone chips in thearea in front of the camera and radar unit.Instead, the whole windscreen should bereplaced.
• Before replacing a windscreen, contactan authorised Volvo workshop to verifythat the correct windscreen is orderedand fitted.
• The same type or Volvo-approved wind- screen wipers must be fitted duringreplacement.
IMPORTANT
When the windscreen is replaced, the camera and radar unit must be recalibrated at theworkshop to ensure the functionality of all thecar
