Camera/radar sensor limitations The camera and radar sensor used by several of the driver support functions has certainlimitations, which also affect the functionsusing the camera and radar sensor. The drivershould be aware of the following limitations:
Camera and radar
Obstructed camera
The area marked in the illustration must be cleaned regularly and kept free of decals, objects, solar film,etc.
The camera is located on the upper interior section of the windshield along with the radarsensor. Do not place, affix or mount anything on the inside or outside of the windshield, or in frontof or around the camera and radar sensor –this could disrupt camera and radar-basedfunctions. It could cause functions to bereduced, deactivated completely or to producean incorrect function 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,pedestrians and large animals in front of thevehicle and that the vehicle's camera andradar-based functions may be obstructed.
The following table shows some of the situa- tions that can cause the message to be dis-played, and suggested actions:
Cause Action
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 thecamera's range of visibility. No action. Heavy precipitation may sometimes prevent the camera/radar sensorfrom functioning.

DRIVER SUPPORT
310
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 cam-era/radar sensor. 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.
Bright sunlight. No action. The camera/radar sensor will reset automatically when lighting con-ditions improve.
High temperatures
If the temperature in the passenger compart- ment is very high, the camera/radar sensorwill switch off temporarily forapprox. 15 minutes after the engine is startedto protect its electronic components. Whenthe temperature has cooled sufficiently, thecamera/radar sensor will automatically restart.
Damaged windshield
NOTE
Failure to take action could result in reduced performance for the driver supportsystems that use the camera and radarunit. It could cause functions to bereduced, deactivated completely or to pro-duce an incorrect function response.
To avoid the risk of malfunction of the driver support systems that use the radar sensor, thefollowing also apply:
If there are cracks, scratches or stonechips on the windshield in front of any ofthe camera and radar sensor "windows"and this covers an area ofabout 0.5 × 3.0 mm (0.02 × 0.12 in.) ormore, contact a workshop to have the windshield replaced 50
.
Volvo advises
against repairing cracks,
scratches or stone chips in the area in front of the camera and radar sensor – theentire windshield should instead bereplaced.
Before replacing the windshield, contact a workshop 50
to verify that the right wind-
shield has been ordered and installed.
The same type of windshield wipers or wipers approved by Volvo should be usedfor replacement.
If the windshield is replaced, the cameraand radar sensor must be recalibrated by a workshop 50
to help ensure proper func-
tioning of all of the vehicle's camera and radar-based systems.
Radar
Vehicle speed
The radar sensor's ability to detect a vehicle ahead is significantly reduced if the speed ofthe vehicle ahead differs greatly from yourvehicle's speed.
50 An authorized Volvo workshop is recommended.

Limited field of vision
The radar sensor has a limited field of vision. In some situations, it may detect a vehicle laterthan expected 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 delayedin certain situations, e.g. if a vehicle pulls in between your vehicle and the vehicledirectly ahead.
Small vehicles, such as motorcycles, or vehicles that are not driving in the centerof the lane 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 impossible for the radar to detect. The driver should be extra alert when driving behind vehi- cles towing low trailers when Adaptive Cruise Control
* or Pilot Assist * is activated.
Camera
Reduced visibility
Cameras have the same limitations as the human eye. In other words, their “vision" isimpaired by adverse weather conditions suchas heavy snowfall/rain, dense fog, swirlingdust/snow, etc. These conditions may reduce the function of systems that depend on thecamera or cause these systems to temporarilystop functioning. Strong sunlight, reflections from the road sur- face, ice or snow covering the road, a dirtyroad surface, or unclear lane marker lines maydrastically reduce the camera

Park Assist Camera *
Blind sectors
There are "blind" sectors between the cameras' fields of vision.
With Park Assist Camera's 360° view *
selected, objects/obstacles may not be detected if they are located in the "joints"where the edges of the individual cameraviews meet.
WARNING
Even if it seems as though only a fairly small section of the screen image isobstructed, this may mean that a relativelylarge sector is hidden and obstacles theremay not be detected until they are verynear the vehicle.
Defective camera
If a camera sector is dark and contains this symbol, thisindicates that the camera isnot functioning properly. See the following illustration for an example.
The vehicle's left-side camera is malfunctioning.
A dark camera sector may also be displayed in the following situations, but without the
defective camera symbol: a door is open
the trunk lid is open
a rearview mirror is folded in
Lighting conditions
The camera image is automatically adjusted according to the current lighting conditions.This means that the brightness and quality of the image may vary slightly. Poor lighting con-ditions may result in reduced image quality.
Rear Park Assist Camera
NOTE
A bike carrier and other accessories moun- ted on the rear of the vehicle can obscurethe camera's view.

Recommended camera and radar sensor maintenance
In order for the camera and radar sensor to function properly, they must be kept free ofdirt, ice, snow, etc. and should be washedregularly with water and car washing deter-gent.
NOTE
Dirt, ice and snow covering the sensors could cause false warnings, reduced func-tion, or no function.
Location of the Park Assist sensors.
Location of rear radar sensors. Keep the marked area clean (on both the left and right sides of the vehicle).
For best possible performance, it is impor- tant to keep the areas in front of the sen-sors clean.
Do not attach any objects, tape or decalsto the surface of the sensors.
Clean the camera lenses regularly usinglukewarm water and car washing deter-gent. Wash gently to avoid scratching thelens.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.
