Radar sensor limitations
The radar sensor used by several of the driver support functions has certain limitations, whichalso affect the functions using the radar sensor.
Obstructed camera
The area marked in the illustration must be kept free of decals, objects, solar film, etc. 69
The radar sensor is located on the upper interior section of the windshield along with the camera.
CAUTION
Do not place, affix or mount anything on the inside or outside of the windshield, or in frontof or around the camera and radar unit – thiscould disrupt camera and radar-based func-tions. It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response.
If this symbol and the message "Windscreen sensor Sensor
blocked, see Owner's manual" is
displayed in the instrument panel, it
means that the camera and radar sensor are unable to detect other vehicles, cyclists, pedes-trians and large animals in front of the vehicleand that the vehicle's camera and radar-basedfunctions may be obstructed, reduced, completelydisabled or providing inaccurate responses.
The following table shows some of the situations that can cause the message to be displayed, and suggested 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 in front of the camera/radar sensor and remove dirt, iceand snow.
Thick fog, heavy rain or snow is blocking the radar signals or the camera'srange of visibility. No action. Heavy precipitation may sometimes prevent the camera/radar sensorfrom functioning.

CauseAction
Water or snow is spraying/swirling up and blocking the radar signals or the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the cam-era/radar sensor from functioning.
There is dirt between the inside of the windshield and the camera/radarsensor. Consult a workshop to have the area of the windshield on the inside of the cam-era's casing cleaned. An authorized Volvo workshop is recommended.
NOTE
Keep the windshield in front of the camera and radar unit clean.
Vehicle speedThe radar sensor's ability to detect a vehicle ahead is significantly reduced if:
• the speed of the vehicle ahead differs greatlyfrom your vehicle's speed
Limited field of visionThe radar sensor has a limited field of vision. Insome situations, it may detect a vehicle later thanexpected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles very close to your vehicle may be delayed in cer-tain situations, e.g. if a vehicle pulls in between your vehicle and the vehicle directlyahead.
Small vehicles, such as motorcycles, or vehi- cles that are not driving in the center of thelane may remain undetected.
In curves, the radar may detect the wrong vehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossi- ble for the radar to detect. The driver should beextra alert when driving behind vehicles towing low trailers when Adaptive Cruise Control or Pilot Assist is activated.

High temperaturesIf the temperature in the passenger compartment is very high, the camera/radar sensor will switchoff temporarily for approx. 15 minutes after theengine is started to protect its electronic compo-nents. When the temperature has cooled suffi-ciently, the camera/radar sensor will automati-cally restart.Damaged windshield
CAUTION
If there are cracks, scratches or stone chips on the windshield in front of any of the cam-era and radar unit "windows" and this coversan area of about 0.5 × 3.0 mm(0.02 × 0.12 in.) or more, contact a workshopto have the windshield replaced – an author-ized Volvo workshop is recommended. Failure to take action could result in reduced performance for the driver support systemsthat use the camera and radar unit. It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response. To avoid the risk of loss of function, malfunc- tion or reduced function of the driver supportsystems that use the radar unit, the followingalso apply:
• Volvo advises
against repairing cracks,
scratches or stone chips in the area infront of the camera and radar unit – theentire windshield should instead bereplaced.
• Before replacing the windshield, contactan authorized Volvo workshop to verifythat the right windshield has beenordered and installed.
• The same type of windshield wipers or wipers approved by Volvo should be usedfor replacement.
CAUTION
If the windshield is replaced, the camera and radar unit must be recalibrated by a workshopto help ensure proper functioning of all of thevehicle's camera and radar-based systems –an authorized Volvo workshop is recom-mended.

Recommended maintenance for theradar sensor
In order for the camera/radar sensor to function properly, the area of the windshield in front of theunit must be kept free of dirt, ice, snow, etc. andshould be washed regularly with water and carwashing detergent.
NOTE
Dirt, ice and snow covering the camera and radar unit reduce their function and can makemeasurement impossible. It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response.

Camera
The camera is used by several driver support systems to e.g. detect lane marker lines or roadsigns.
Note: This illustration is general and details may vary depending on model.
The camera is used by the following functions:
• Adaptive Cruise Control
*
• Pilot Assist
*
• Lane Keeping Aid
*
• Steering assistance at risk of collision
• City Safety
• Driver Alert Control
*
• Road Sign Information
*
• Active high beams

Camera limitations
The camera used by several of the driver support functions has certain limitations, which alsoaffect the functions using the camera.
Reduced visibilityThe camera has the same limitations as the human eye. In other words, its “vision" is impairedby adverse weather conditions such as heavysnowfall/rain, dense fog, swirling dust/snow, etc.These conditions may reduce the function of sys-tems that depend on the camera or cause thesesystems to temporarily stop functioning. Strong sunlight, reflections from the road surface, ice or snow covering the road, a dirty road sur- face, or unclear lane marker lines may drastically reduce the camera
