192The driver will then have to reactivate ACC in one of the following ways: •
By pressing
• By accelerating up to at least 3 mph (4 km/h). ACC will then resume following thevehicle ahead.
Your vehicle will then resume following the vehi-cle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehicle at a standstill for up to 4 minutes. After4 minutes have elapsed, the parking brakewill be engaged and ACC will go into standbymode. To reactivate ACC, the driver must release the parking brake (see Parking brake – generalinformation (p. 267)).
Automatic standby mode when ACC changes target vehicles
If the vehicle ahead turns suddenly, there may be a sta- tionary vehicle ahead
The following only applies at speeds below approximately 18 mph (30 km/h) :
If ACC changes target vehicles (the vehicle thatthe radar sensor has detected) from a movingvehicle to a stationary one, the system will applythe brakes in your vehicle.
WARNING
At speeds above 18 mph (30 km/h), ACC
will not react to a stationary vehicle and apply the brakes but will instead accelerate to thepreviously set speed. The driver must activelyapply the brakes to stop the vehicle.
ACC disengages and goes into standby mode if: • Your vehicle's speed goes below 10 mph (15 km/h) and ACC cannot determine if thetarget object is a stationary vehicle or some other type of object such as e.g., a speedbump.
• Your vehicle's speed goes below 10 mph(15 km/h) and the vehicle ahead turns sothat ACC no longer has a target vehicle tofollow.
No automatic braking when at a
standstill
In certain situations, ACC will no longer apply thebrakes and go into standby mode while the vehi-cle is not moving. This means that the driver willhave to apply the brakes. This happens if:
• The driver presses the brake pedal
• The parking brake is activated
• The gear selected is moved to
P, N or R
• The driver presses the
button to put ACC
in standby mode
The parking brake is applied
automatically
In certain situations, ACC will apply the parking brake in order to continue keeping the vehicle ata standstill. This happens if:
• The driver opens the door or takes off his/her seat belt
• The stability system is put in Sport mode(see Stability system – operation (p. 175))

ACC has kept the vehicle at a standstill for more than 2 minutes
• The engine has been switched off
• The brakes have overheated

Radar sensor
The radar sensor is designed to help detect cars or larger vehicles driving in the same direction asyour vehicle, in the same lane.
The radar sensor and its limitationsIn addition to being used by the Adaptive Cruise Control (ACC), the radar sensor is also used byDistance Alert (see Distance Alert – introduction(p. 199)) and Collision Warning with Full Auto-brake and Pedestrian Detection (see Collisionwarning – introduction (p. 210)).
WARNING
• If there is visible damage to the front grille or you suspect that the radar sensormay be damaged in any way, contact atrained and qualified Volvo service techni-cian as soon as possible. The radar sen-sor may only function partially (or not atall) if it is damaged or is not securely fas-tened in place.
• Accessories or other objects, such asextra headlights, must not be installed infront of the grille.
• Modification of the radar sensor couldmake its use illegal.
The radar sensor's capacity to detect vehicles ahead is impeded: • if the radar sensor is obstructed and cannotdetect other vehicles, for example in heavy rain, or if snow or other objects are obscuringthe radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
•
if the speed of vehicles ahead is significantly different from your own speed.

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.

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 – symbols and messages
Symbols and messages in the displayA text message can be erased by pressing briefly on the OK button on the turn signal lever.

an audible signalThe vehicle is at a standstill and ACC will release the brakes before the parking brake engages to keep the vehicle stopped but a problem with the parking brake means that the vehicle may begin to roll. The driver will have to apply the brakes. The message will remain in the display and the audible signal will continue until the driver applies the brakes or presses the accelerator pedal.
-Below 30 km/h Only fol- lowingThis is displayed if you try to activate ACC at speeds below approx. 18 mph (30 km/h) without a vehicle ahead within range (approx. 100 ft/30 meters).

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.
