Steep roads and/or heavy loads
Pilot Assist is primarily intended to be driven onflat roads. The function may not be able to main-tain the correct time interval to the vehicle aheadwhen driving down steep hills. The driver shouldbe extra attentive and prepared to apply thebrakes.
Do not use Pilot Assist if the vehicle is carry-ing a heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer,bike carrier or similar is connected to thevehicle electrical system.
Other limitations
The Off Road drive mode cannot beselected when Pilot Assist is activated.
NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

The previous illustration63 shows that Pilot Assistis set to maintain a speed of 110 km/h (68 mph)and that there is no target vehicle ahead to fol-low.
Pilot Assist will provide steering assistancebecause it can detect the lane's side markinglines.

Radar sensor
The radar sensor is used by several driver sup-port systems to detect other vehicles.
Note: This illustration is general and details may varydepending on model.
The radar sensor is used by the following func-tions:
Distance Alert*
Adaptive Cruise Control*
Lane Keeping Aid
Pilot Assist*
City Safety
Any modifications to the radar sensor may makeits use illegal.

Radar sensor limitations
The radar sensor used by several of the driversupport functions has certain limitations, whichalso affect the functions using the radar sensor.
Obstructed camera
The area marked in the illustration must be kept free ofdecals, objects, solar film, etc.64
The radar sensor is located on the upper interiorsection of the windshield along with the camera.
CAUTION
Do not place, affix or mount anything on theinside 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 Sensorblocked, see Owner's manual" isdisplayed in the instrument panel, itmeans that the camera and radar sensor areunable 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 orcovered 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.
64Note: This illustration is general and details may vary depending on model.

328
CauseAction
Water or snow is spraying/swirling up and blocking the radar signals orthe 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 cameraand radar unit clean.
Vehicle speed
The radar sensor's ability to detect a vehicleahead is significantly reduced if:
the speed of the vehicle ahead differs greatlyfrom 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 at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles veryclose 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 wrongvehicle 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 towinglow trailers when Adaptive Cruise Control or PilotAssist is activated.

High temperatures
If the temperature in the passenger compartmentis 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 chipson 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 reducedperformance 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 orwipers approved by Volvo should be usedfor replacement.
CAUTION
If the windshield is replaced, the camera andradar 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 functionproperly, 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 andradar unit reduce their function and can makemeasurement impossible.
It could cause functions to be reduced, deac-tivated completely or produce an incorrectfunction response.
