body and the person must be at least 32 in. (80 cm) tall.
• The system cannot detect a pedestrian carry-ing a large object.
• The camera's capacity to see a pedestrian atdawn or dusk is limited, much as it is for thehuman eye.
• The camera's function is deactivated and willnot detect a pedestrian in darkness or in tun-nels, even if there is street lighting in thearea.
WARNING
•Pedestrian and Cyclist Detection with Full Auto Brake is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is alwaysresponsible for operating the vehicle in asafe manner.
• The system cannot detect all pedestriansin all situations, such as in darkness/atnight and cannot detect partially hiddenpedestrians, people who are less thanapprox. 32 in. (80 cm) tall, or peoplewearing clothing that obscures the con-tours of their bodies.

Collision warning
* – limitations
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver is notlooking straight ahead may make the visual warn-ing signal in the windshield difficult to see. Forthis reason, always activate the audible warningsignal. Slippery driving conditions increase braking dis- tance, which can reduce the system's capacity toavoid a collision. In these conditions, the ABS andstability systems provide the best possible brak-ing effect while helping to maintain stability.
NOTE
The visual warning signal may be temporarily disengaged in the event of high passengercompartment temperature due to strong sun-light, etc. If this occurs, the audible warningsignal will be used, even if it has been deacti-vated in the menu system.

WARNING
• In certain situations, the system cannot provide warnings or warnings may bedelayed if traffic conditions or other exter-nal factors make it impossible for theradar sensor or camera to detect apedestrian, a cyclist or a vehicle ahead.
• Warnings may not be provided if the dis-tance to the vehicle ahead is short, or ifmovements of the steering wheel/brakepedal are great, such as during activedriving.
• The sensor system has a limited range forpedestrians/cyclists and provides warn-ings and braking effect most effectively atspeeds up to 30 mph (50 km/h). For sta-tionary or slow-moving vehicles, the sys-tem functions best if your vehicle

Collision warning – troubleshooting
Fault tracing and actionsIf the message Windscreen Sensors blockedis displayed, this means that the camera isobscured and cannot detect pedestrians, cyclists, vehicles or road marker lines in front of the vehi-cle. This, in turn, means that Pedestrian and Cyclist Detection with Full Auto Brake, Driver Alert Con-trol, Lane Departure Warning or Lane KeepingAid will not have full functionality. The table lists possible causes for this message being displayed, and suitable actions.
Cause
Action
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.
Fog, heavy rain or snow is interfering with the function of the camera. No action possible. Heavy precipitation may affect the function of the cam- era.
The surface of the windshield is clean but the message remains in the display. Wait a short time. It may take several minutes for the camera to register vis- ibility.
The surface between the inside of the windshield and the camera is dirty. Contact an authorized Volvo retailer or service technician to have this sur- face cleaned.

Driver Alert SystemThe Driver Alert System is designed to help a driver who may be becoming fatigued or who isinadvertently leaving the lane.
IntroductionThe Driver Alert System consists of two different functions that can be switched on together orseparately.
• Driver Alert Control (DAC)
, see Driver Alert
Control (DAC) – introduction (p. 214)
• Lane Departure Warning (LDW) 9
, see Lane
Departure Warning (LDW) – introduction(p. 220)
or
• Lane Keeping Aid (LKA) 10
, see Lane Keep-
ing Aid (LKA) – introduction (p. 225)
When one or both of the functions has beenswitched on, it is in standby mode and is acti-vated when the vehicle exceeds a speed of40 mph (65 km/h). The function deactivates if the vehicle's speed goes under 37 mph (60 km/h). Both functions use a camera that is dependent on the road/lane being clearly marked by paintedlines on each side.
WARNING
The Driver Alert System does not function in all situations and is designed to be a supple-mentary aid. It is not, however, intended toreplace the driver
