Collision warning – troubleshooting
Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the
camera is obscured and cannot detect pedestrians, cyclists, vehicles or road marker lines in front of the vehicle. This, in turn, means that Pedestrian and Cyclist Detection with Full Auto Brake, DriverAlert Control, Lane Departure Warning or
Lane Keeping Aid will not have full functional-ity. The table lists possible causes for this mes- sage being displayed, and suitable actions.
CauseAction
The surface of the windshield in front of the camera is dirty or covered with ice or snow.Clean or clear the section of the windshield in front of the camera.

Park assist – introduction
The park assist system is designed to assist you when driving into parking spaces,garages, etc. An audible signal and symbolsin the audio system’s display indicate the dis-tance to the object. The park assist system utilizes ultrasound sensors in the front bumper and rearbumper(s) to measure the distance to a vehi-cle or an object that may be close to the frontor rear of your vehicle.
NOTE
A trailer hitch whose wiring is integrated with the vehicle's electrical system will beincluded in the measurement of the availa-ble space behind the vehicle.
WARNING
Park Assist is an information system, NOT a safety system. This system is designedto be a supplementary aid when parkingthe vehicle. It is not, however, intended toreplace the driver's attention and judge-ment.

Signals from the park assist system
View in the display (warning for objects front left/ right rear)
Visual indicatorThe audio system’s display gives an overview of the vehicle’s position in relation to adetected object. The marked sectors in the display indicate that one or more of the sensors has detectedan object. The closer the car symbol comesto a sector, the closer the vehicle is to theobject. If the infotainment system is switched off, the park assist system will not be able to providea visual indicator. An audible signal will stillbe provided.

Audible signalThe Park Assist system uses an intermittent tone that pulses faster as you come close toan object, and becomes constant when youare within approximately 1 ft (30 cm) of anobject in front of or behind the vehicle. Ifthere are objects within this distance bothbehind and in front of the vehicle, the tonealternates between front and rear speakers.
NOTE
The level of the audible signal can be low- ered/raised with the infotainment volumecontrol. The level can also be set in the MYCAR menu system. See My Car – introduc-tion (p. 76) for a description of the menusystem.
If the volume of another source from the audio system is high, this will be automati-cally lowered.
Rear park assist
G017833
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The system must be deactivated when towing a trailer, carrying bicycles in a rear-mountedcarrier, etc, which could trigger the rear parkassist system's sensors.
NOTE
•Rear park assist is deactivated auto- matically when towing a trailer if Volvogenuine trailer wiring is used. If a non-Volvo trailer hitch is being used, it maybe necessary to switch off the systemmanually, see Park assist – operation(p. 234).
• The system will not detect highobjects, such as a loading dock, etc.
• Objects such as chains, thin shinypoles or low objects may temporarilynot be detected by the system. Thismay result in the pulsing tone unex-pectedly stopping instead of changingto a constant tone as the vehicleapproaches the object. In such cases,use caution when backing up or stopthe vehicle to help avoid damage.

Front park assist is deactivated when the parking brake is applied and or when thegear selector is in the P position.
