WARNING
• In certain situations, the system can- not provide warnings or warnings maybe delayed if traffic conditions or otherexternal factors make it impossible forthe radar sensor or camera to detect apedestrian, a cyclist or a vehicleahead.
• Warnings may not be provided if thedistance to the vehicle ahead is short,or if movements of the steering wheel/brake pedal are great, such as duringactive driving.
• The sensor system has a limited rangefor pedestrians/cyclists and provideswarnings and braking effect mosteffectively at speeds up to 30 mph(50 km/h). For stationary or slow-mov-ing vehicles, the system functions bestif your vehicle’s speed is belowapproximately 45 mph (70 km/h).
• Warnings for stationary or slow-mov-ing vehicles may not be provided indark conditions or in poor visibility.
The Pedestrian and Cyclist Detection with Full Auto Brake system uses the same radar sen-sors as Adaptive Cruise Control. For moreinformation on the radar sensor and its limita-tions, see Adaptive Cruise Control – limita-tions (p. 181).
NOTE
If warnings are given too frequently, the warning distance can be reduced (see Col-lision warning* – operation (p. 200)). Thiscauses the system to provide later warn-ings, which decreases the total number ofwarnings provided.
WARNING
•The system is not activated at speeds under approx. 2 mph (4 km/h). There-fore, it will not brake your vehicle if youapproach a vehicle ahead at very lowspeed, such as when parking.
• The driver's actions always have high-est priority and override the Pedestrianand Cyclist Detection with Full AutoBrake system. This means that thesystem will not intervene in situationswhere the driver is actively steering,braking or pressing the acceleratorpedal, even if a collision is imminent.
• When Auto-brake has prevented a col-lision with a stationary object, yourvehicle will remain at a standstill forapprox. 1.5 seconds. If your vehiclehas been braked for a moving vehicleahead, your vehicle's speed will bereduced to the same speed as thatvehicle's.

The camera’s limitations
The camera has the same limitations as the human eye. The camera is used by Pedestrian and Cyclist Detection with Full Auto Brake Collision warn-ing – introduction (p. 197), Active High Beams(Active high beams (AHB)* (p. 84)), Road SignInformation (Road Sign Information (RSI)* –introduction (p. 167)) and Driver Alert System(Driver Alert System (p. 210)) with LaneDeparture Warning or Lane Keeping Aid.
NOTE
• To help protect the camera in very hot conditions, it may be temporarilyswitched off for approximately 15minutes after the engine has beenstarted.
• Keep the section of the windshield infront of the camera clean and free ofice, snow, or condensation.
WARNING
•
The camera has the same type of limi- tations as the human eye, i.e., it can-not see as well in heavy snowfall orrain, thick fog or in heavy blowing dustor snow. In such conditions, systemsdepending on the camera may experi-ence greatly reduced functionality ormay be temporarily deactivated.
• Never place any objects, decals, etc.,on the windshield in front of the cam-era. This could reduce or block thecamera’s function, and could causeone or more of the systems that utilizethe camera to stop functioning.
• Strong sunlight, reflections from theroad surface, ice or snow covering theroad, a dirty road surface, or unclearlane marker lines may drasticallyreduce the camera’s capacity todetect the side of a lane, a pedestrian,a cyclist or another vehicle.

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.
Fog, heavy rain or snow is interfering with the function of the camera.No action possible. Heavy precipitation may affect the function of the camera.
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 regis- ter visibility.
The surface between the inside of the windshield and the camera is dirty.Contact an authorized Volvo retailer or service technician to have this surface cleaned.

.
In order to function properly, the camera and radar sensor must be kept clean. Dirt, ice,snow, etc., will reduce the function of thesecomponents. Remove ice and snow when necessary and wash these areas regularly with a suitable carwashing liquid.

Collis'n warning OFFPedestrian and Cyclist Detection with Full Auto Brake is switched off. This message is displayed when the engine is started and will disappear after approx. 5 seconds. It can also be erased by pressing the OK but-
ton.
Collision Warning UnavailablePedestrian and Cyclist Detection with Full Auto Brake cannot be activated. This message is displayed when the driver attempts to activate the function. It will disappear after approx. 5 seconds or can be erased bypressing the OK button.
Auto braking was activatedAuto-braking has been active. This message can be erased by pressing the OK button.
Windscreen Sen- sors blockedThe camera is temporarily not functioning. This message is displayed if the camera is obstructed by snow, ice, dirt, etc., on the windshield. Clean the area of the windshield in front of the camera, see The camera’slimitations (p. 205) for more information on the camera’s limitations.
Radar blocked See manualPedestrian and Cyclist Detection with Full Auto Brake is temporarily not functioning. The radar sensor is blocked, for example by heavy rain or snow that has accumulated in front of the sensor, and cannot detectother vehicles, see Adaptive Cruise Control – limitations (p. 181) for more information on the radar sensor’slimitations.
Collision warn. Service requiredPedestrian and Cyclist Detection with Full Auto Brake is partially or completely not functioning. Contact a trained and qualified Volvo service technician if the message remains in the display.

Driver Alert System
The Driver Alert System is designed to help a driver who may be becoming fatigued or whois inadvertently leaving the lane.
IntroductionThe Driver Alert System consists of two differ-ent functions that can be switched ontogether or separately.• Driver Alert Control (DAC)
, see Driver
Alert Control (DAC) – introduction (p. 210)
• Lane Departure Warning (LDW) 7
, see
Lane Departure Warning (LDW) – intro-duction (p. 215)
or
• Lane Keeping Aid (LKA) 8
, see Lane
Keeping Aid (LKA) – introduction (p. 220)
When one or both of the functions has been switched 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 depend- ent on the road/lane being clearly marked bypainted lines on each side.
WARNING
The Driver Alert System does not function in all situations and is designed to be asupplementary aid. It is not, however,intended to replace the driver’s attentionand judgement.
Driver Alert Control (DAC) – introduction
DAC is intended to alert the driver if his/her driving becomes erratic, such as if the driveris distracted or fatigued. DAC is designed to help detect a slowly changing driving pattern. It is primarilyintended to be used on main roads and is notmeant for use in city traffic.
A camera monitors the painted lines marking the lane in which the vehicle is traveling andcompares the direction of the road with thedriver’s movements of the steering wheel.The driver is alerted if the vehicle does notfollow the lane smoothly.
7 Models with 5- or 6-cylinder engines only.
8 Models with 4-cylinder engines only.

NOTE
The camera has certain limitations, see Adaptive Cruise Control – limitations(p. 181).
WARNING
•DAC is not intended to extend the duration of driving. Always plan breaksat regular intervals to help remain alert.
• A warning from DAC should not beignored. A driver may not be aware ofhow fatigued he/she has become.
• In certain cases, fatigue may not affectthe driver’s behavior. In situations ofthis type, no warning will be provided.Therefore, it is important to takebreaks at regular intervals, regardlessof whether or not DAC has given awarning.
