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.
The distance to the vehicle ahead (in the same lane) is monitored by a radar sensor. Your vehi-cle's speed is regulated by accelerating andbraking. The brakes may emit a sound when theyare being modulated by the adaptive cruise con-trol system. This is normal.
WARNING
The brake pedal moves when the adaptive cruise control system modulates the brakes.Do not rest your foot under the brake pedal.
The ACC system is designed to smoothly regu- late speed. However, the driver must apply thebrakes in situations that require immediate brak-ing. This applies when there are great differencesin speed between vehicles, or if the vehicle aheadbrakes suddenly.
WARNING
Due to limitations in the radar sensor, braking may occur unexpectedly or not at all, seeAdaptive Cruise Control – limitations (p. 186).
Adaptive Cruise Control can be put in active mode at any permitted speed. However, if thevehicle's speed falls below 18 mph (30 km/h) orif engine speed (rpm) becomes too low, ACC dis-engages (goes into standby mode) and will nolonger modulate the brakes. The driver will thenhave to maintain a safe distance to the vehicleahead.
WARNING
When Adaptive Cruise Control is in standby mode or is switched off completely, thebrakes will not be modulated automatically.The driver must assume full control over thevehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force that is equivalent to approximately 40% of thevehicle's total braking capacity. In situationsrequiring more brake force than ACC can provideand if the driver does not apply the brakes, anaudible signal from the Collision Warning systemwill sound and warning light will illuminate (see Collision warning * – function (p. 204)) in the
windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

Adaptive Cruise Control – limitationsThe ACC cannot cover all driving situations and traffic, weather and road conditions.
Situations where ACC may not function optimally
WARNING
• The radar sensor has a limited field of vision. In some situations it may detect avehicle later than expected or not detectother vehicles at all.
• If ACC is not functioning properly, cruisecontrol will also be disabled.
Radar sensor's field of vision (shown in pink)
In certain situations, the radar sensor cannot detect vehicles at close quarters, for examplea vehicle that suddenly enters the lanebetween your vehicle and the target vehicle.
Small vehicles, such as motorcycles, or vehi- cles not driving in the center of the lane mayremain undetected.
In curves, the radar sensor may detect the wrong vehicle or lose sight of the target vehi-cle.
WARNING
•
Adaptive Cruise Control cannot cover all driving situations and traffic, weather androad conditions. The "Function" sectionprovides information about limitations thatthe driver must be aware of before usingthis feature.
• This system is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance and speedand must intervene if Adaptive CruiseControl does not maintain a suitablespeed or suitable distance to the vehicleahead.
• Maintenance of ACC components mayonly be performed by a trained and quali-fied Volvo technician.

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.

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.

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.

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.

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.
