WARNING
•Pedestrian and Cyclist Detection with Full Auto Brake does not work in all driving,traffic, weather and road conditions. Itdoes not react to vehicles not traveling inthe same direction as your vehicle.
• Pedestrian and Cyclist Detection with FullAuto Brake does not react to animals.
• Warnings are only provided when the riskof collision is high. The "Function" sectionprovides information about limitations thatthe driver must be aware of before usingCollision Warning.
• Pedestrian and Cyclist Detection with FullAuto Brake will not provide a warning orbrake the vehicle for pedestrians orcyclists at speeds above 50 mph(80 km/h).
WARNING
•
Pedestrian and Cyclist Detection with Full Auto Brake will not provide a warning orbrake the vehicle for pedestrians in dark-ness or in tunnels, even if there is streetlighting in the area.
• The auto-brake function can help preventa collision or reduce the speed at impactbut the driver should always apply thebrakes for the best possible brakingeffect, even if auto-brake is actively apply-ing the brakes.
• Never wait for a collision warning. Thissystem is designed to be a supplemen-tary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance andspeed, even when the collision warningsystem is in use.
• Maintenance of the Pedestrian andCyclist Detection with Full Auto Brakesystem's components must only be per-formed by a trained and qualified Volvotechnician.

Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work together to detect a pedestrian, a cyclist, stationary vehi-cles and vehicles that are moving in the samedirection as your vehicle. If there is a risk of colli-sion with a vehicle, a cyclist or a pedestrian, thedriver is alerted by a flashing red warning lightand an audible warning signal. The system isactive at speeds above 3 mph (4 km/h).
Brake SupportIf the risk of collision continues to increase afterthe collision warning has been given, Brake Sup-port is activated. Brake Support prepares thebrake system to react quickly, and the brakes areapplied slightly. This may be experienced as alight tug. If the brakes are applied quickly, full braking effect will be provided. Brake Support alsoincreases brake force if the system determinesthat the driver has not applied adequate pressureon the brake pedal.
Auto-brakeIf a collision is imminent and the driver has notapplied the brakes or begun to steer around thevehicle, pedestrian or a cyclist, the auto-brakefunction is activated without the driver pressingthe brake pedal. Full brake force is applied tohelp reduce the vehicle

WARNING
Pedestrian and Cyclist Detection with Full Auto Brake is designed to be a supplemen-tary driving aid. It is not, however, intended toreplace the driver's attention and judgement.The driver is always responsible for operatingthe vehicle in a safe manner. The system cannot detect a bike/cyclist if:
• He/she is wearing loose-fitting clothing that may obscure body contours
• The bike is approaching your vehicle fromthe side
• The bike is not equipped with a rear-fac-ing red reflector
• The bike is carrying large objects
• Most of the cyclist's body or the bikeitself cannot be "seen" by the system'scamera

The system cannot identify all pedestrians
The Pedestrian and Cyclist Detection with Full Auto Brake system can only identify and detect apedestrian who is standing upright. This personcan be standing still, walking or running. This means that the system has to be able to identify a person's head, arms, shoulders, legs,the upper and lower parts of the body and a per-son's pattern of movement when walking or run-ning. If parts of the body are not visible to the camera, the system cannot detect the pedestrian. The following conditions apply:
• In order to detect a pedestrian, the system must have a full view of the person's entire

• 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.

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.
