WARNING
•Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible for applying the brakes if thesystem does not detect another vehicle.
• Adaptive Cruise Control does not react topeople or animals, or small vehicles suchas bicycles and motorcycles. It also doesnot react to slow moving, parked orapproaching vehicles, or stationaryobjects.
• Do not use Adaptive Cruise Control indemanding driving conditions such as citydriving or other heavy traffic situations, inslippery conditions, when there is a greatdeal of water or slush on the road, duringheavy rain or snow, in poor visibility, onwinding roads or on highway on- or off-ramps.

Adaptive Cruise Control – troubleshooting
If the message Radar blocked See manual is
displayed, this means that the radar signals from the sensor have been obstructed and that a vehi- cle ahead cannot be detected. This, in turn, means that the functions of the ACC, Distance Alert, and Collision Warning Sys-
tem with Auto-brake and Pedestrian Detectionwill not function. The table lists possible causes for this message being displayed, and suitable actions.
CauseAction
The surface of the radar in the grille is dirty or obstructed in some way.Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the radar.
Swirling water or snow from the surface of the road may interfere with the radar signals.No action possible. A very wet or snow-covered road surface may affect the function of the radar.
The surface of the radar is clean but the message remains in the display.Wait a short time. It may take several minutes for the radar to detect that it is no longer obstructed.

Distance Alert – introduction
Distance Alert is part of Adaptive Cruise Control and is a function that provides information aboutthe time interval to the vehicle ahead.
IntroductionDistance Alert is active at speeds above approxi- mately 18 mph (30 km/h). Time interval informa-tion is only given for a vehicle that is drivingahead of your vehicle in the same direction. Noinformation is provided for vehicles driving towardyou, moving very slowly, or at a standstill.
Amber warning light 3
.
An amber warning light in the windshield glows steadily if your vehicle is closer to the one aheadthan the set time interval.
NOTE
Distance Alert only monitors distance to the vehicle ahead while Adaptive Cruise Control isin standby mode or off.
WARNING
Distance Alert only indicates the distance to the vehicle ahead. It does not affect thespeed of your vehicle.

Collision warning – introduction Pedestrian and Cyclist Detection with Full Auto Brake is designed to assist the driver if there is arisk of a collision with a pedestrian, a cyclist, avehicle ahead that is at a standstill or one that ismoving in the same direction as your vehicle.
This system consists of the following three func- tions:
• Collision Warning
warns the driver of a
potential collision situation.
• Brake Support
helps the driver brake effi-
ciently in a critical situation.
• Auto-brake
brakes the vehicle automatically
if a collision with a pedestrian, a cyclist oranother vehicle cannot be avoided and thedriver does not apply the brakes in time orsteer around the person/vehicle. Auto-brakecan help prevent a collision or reduce thespeed at which a collision occurs.
Since Pedestrian and Cyclist Detection with FullAuto Brake is activated in circumstances wherethe driver should have begun braking muchsooner, the system will not be able to assist thedriver in all situations. This system is designed to activate as late as possible to help avoid unnecessary intervention. The system should not be used in such a way that the driver changes his/her way of operatingthe vehicle. If the driver relies entirely on the sys- tem, the chances of an accident eventually occur-ring increase considerably. The Pedestrian and Cyclist Detection with Full Auto Brake and City Safety
™ systems supple-
ment each other. See City Safety – introduction (p. 195) for detailed information about City Safety ™.
WARNING
No automatic system can be guaranteed to function 100% correctly in all situations. Forthat reason, never test the Auto-brake systemby driving toward a person or object. Thiscould result in serious injury or death.

* Option/accessory, for more information, see Introduction.203
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.

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
