Automatic deactivationCruise control is automatically deactivated temporarily if one of the following occurs:
• If the speed drops below approximately 20 mph (30 km/h).
• When the brake pedal is depressed.
• If the gear selector is moved to positionN.
• During wheel spin or wheel lock-up.
• If the vehicle's speed is increased byusing the accelerator pedal for more than1 minute.
The currently set speed will be saved in the system's memory.
Temporary deactivationThe driver can temporarily deactivate cruisecontrol by pressing 0. The saved speed is
shown in brackets in the information display.
Resume set speedIf cruise control has been deactivated tempo- rarily, it can be reactivated by pressing
.
The vehicle's speed returns to the most recently set speed.
WARNING
There may be a significant increase in speed after the
button has been
pressed.
Deactivation
Cruise control is disengaged by pressing or by switching off the engine. The set speed is cleared.
WARNING
Cruise control should not be used in heavy traffic or when driving on wet or slipperyroads. Cruise control may not maintain setspeed on steep downgrades.

2-second interval will vary according the speed of the vehicles.
WARNING
•
Adaptive Cruise Control is not a colli- sion avoidance system. The driver isalways responsible for applying thebrakes if the system does not detectanother vehicle.
• Adaptive Cruise Control does not reactto people or animals, or small vehiclessuch as bicycles and motorcycles. Italso does not react to slow moving,parked or approaching vehicles, orstationary objects.
• Do not use Adaptive Cruise Control indemanding driving conditions such ascity driving or other heavy traffic situa-tions, in slippery conditions, whenthere is a great deal of water or slushon the road, during heavy rain orsnow, in poor visibility, on windingroads or on highway on- or off-ramps.
The distance to the vehicle ahead (in the same lane) is monitored by a radar sensor.Your vehicle's speed is regulated by acceler-ating and braking. The brakes may emit asound when they are being modulated by the adaptive cruise control system. This is nor-mal.
WARNING
The brake pedal moves when the adaptive cruise control system modulates thebrakes. Do not rest your foot under thebrake pedal.
The ACC system is designed to smoothly regulate speed. However, the driver mustapply the brakes in situations that requireimmediate braking. This applies when thereare great differences in speed between vehi-cles, or if the vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, braking may occur unexpectedly or not atall, see page 151.
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)or if engine speed (rpm) becomes too low,ACC disengages (goes into standby mode) and will no longer modulate the brakes
2
. The driver will then have to maintain a safe dis- tance to the vehicle ahead.
WARNING
When Adaptive Cruise Control is in standby mode or is switched off com-pletely, the brakes will not be modulatedautomatically. The driver must assume fullcontrol over the vehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force that is equivalent to approximately 40% ofthe vehicle's total braking capacity. In situa-tions requiring more brake force than ACCcan provide and if the driver does not applythe brakes, an audible signal from the Colli-sion Warning system will sound and warninglight will illuminate (see page 165) in thewindshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead maymake the visual warning signal in the wind-shield difficult to see.

146* Option/accessory, for more information, see Introduction.
WARNING
Adaptive Cruise Control only warns of vehicles detected by the radar sensor, seepage 151. In some cases there may be nowarning or the warning may be delayed.The driver should always apply the brakeswhen necessary.
Steep inclines and/or heavy loadsACC is primarily intended for use on fairly level roads. The system may have difficultymaintaining the correct distance to a vehicleahead on steep inclines, if the vehicle is car-rying a heavy load or is towing a trailer. Inthese situations, the driver should always beprepared to apply the brakes if necessary.

• Press
.
This symbol and the marking for the set speed with change colors from green to
white. The previously set speed and time interval are resumed by pressing
.
WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Standby mode due to action by the driver
ACC is temporarily deactivated and put in standby mode:
• if the brakes are applied
• if the gear selector is moved to
N
• if the driver drives faster than the set speed for more than
1 minute.
In this happens, the driver will have to regu- late the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for a short time, such as when passinganother vehicle, ACC is deactivated tem-porarily and is reactivated when the pedalis released.
Automatic standby modeACC is linked to other systems such as the stability and traction control system (DSTC). Ifthis system is not functioning properly, ACCwill switch off automatically. In the event of automatic deactivation, an audible signal will sound and the message
Cruise control Cancelled is shown in the
instrument panel. The driver must then inter- vene and adapt the vehicle's speed to thesurrounding traffic and regulate the distanceto the vehicle ahead. An automatic switch to standby mode may be caused if:
• engine speed (rpm) is too high/low
• The driver's door is opened
• The driver unbuckles his/her seat belt
• the vehicle's speed goes below 18 mph (30 km/h) 4
• the wheels lose traction •
brake temperature is high
• the radar sensor is obstructed by, for example, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactiva- ted by pressing the
button on the steering
wheel keypad. The vehicle will return to the most recently set speed.
WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Passing another vehicleIf your vehicle’s speed is being regulated by ACC and the driver indicates that he/shewould like to pass the vehicle ahead by usingthe left turn signal, ACC can assist by accel-
erating briefly. This function is active at speeds above approximately 45 mph (70 km/h).

WARNING
Please be aware that this function will also cause the vehicle to accelerate briefly incertain situations other than passinganother vehicle, for example using the leftturn signal to indicate a lane change or aturn toward a highway exit at speedsabove approximately 45 mph (70 km/h).
Turning ACC off completely
•
From standby mode, press once.
• From active mode, press
twice.
The set speed and time interval are then cleared from the system's memory and can- not be resumed by pressing
.
Toggling between ACC and CC (standard Cruise Control)
Switching from ACC to CCThis may be useful if, for example, the radar sensor is obstructed in some way. See thesection "The radar sensor and its limitations"on page 151 for additional information.
• Press and hold the
button; the symbol
in the instrument panel will switch from
to .
> This activates the standard cruise control function (see page 142).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automati-
cally maintain a set distance to a vehi- cle ahead.
• Only the set speed will be maintainedand the driver will have to apply thebrakes when needed.
Switching from CC to ACC
Switch off cruise control by pressing once
or twice as needed according to the instruc- tions in the previous section "Turning ACC offcompletely." The next time the system isswitched on, ACC will be reactivated.
Queue Assist
IntroductionQueue Assist is an added ACC feature that is linked to your vehicle's automatic transmis-sion. Queue Assist consists of the following func- tions: • Enhanced speed interval (including when the vehicle is at a complete stop or is moving at speed below 18 mph(30 km/h))
• Automatic standby mode when ACCchanges target vehicles
• No automatic braking when at a standstill
• The parking brake is applied automati-cally
Please note that the lowest speed that can be set is 18 mph (30 km/h), although ACC canmaintain a set speed/distance to a vehicleahead down to a standstill. Queue Assistconsists of the following features:
Enhanced speed interval
NOTE
The driver's door must be closed and the driver's seat belt must be fastened beforeACC can be put in active mode. If the driv-er's seat belt is taken off or if the driver'sdoor is opened, ACC will return to standbymode.
Your vehicle can maintain the set time interval to the vehicle ahead at any permissiblespeed, including a complete stop. In order to activate ACC at speeds below 18 mph (30 km/h):

04 Driver support
Adaptive Cruise Control (ACC)*
04
150* Option/accessory, for more information, see Introduction.
• The vehicle ahead must be within a rea- sonable distance (not farther away thanapprox. 100 ft/30 meters)
• The lowest speed that can be selected is18 mph (30 km/h), although ACC will alsohelp maintain the set time interval to thevehicle ahead at lower speeds, includinga complete stop.
During short stops (less than approximately 3 seconds) in slow-moving traffic, your vehi-cle will begin moving again automatically assoon as the vehicle ahead begins to move. If it takes more than 3 seconds for the vehicle ahead to begin moving, ACC will be automat-ically go into standby mode. The 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 followingthe vehicle ahead.
Your vehicle will then resume following the vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehicle at a standstill for up to 4 minutes.After 4 minutes have elapsed, the parkingbrake will be engaged and ACC will go intostandby mode. To reactivate ACC, the driver must release the parking brake (see page 133).
Automatic standby mode when ACC changes target vehicles
If the vehicle ahead turns suddenly, there may be a stationary vehicle ahead
The following only applies at speeds below approximately 18 mph (30 km/h) :
If ACC changes target vehicles (the vehicle that the radar sensor has detected) from amoving vehicle to a stationary one, the sys-tem will apply the 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 acceler-ate to the previously set speed. The drivermust actively apply the brakes to stop thevehicle.
ACC disengages and goes into standby mode if:
• Your vehicle's speed goes below 10 mph (15 km/h) and ACC cannot determine ifthe target object is a stationary vehicle orsome other type of object such as e.g., aspeed bump.
• 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 the brakes and go into standby mode whilethe vehicle is not moving. This means that thedriver will have 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 park- ing brake in order to continue keeping thevehicle at a standstill. This happens if:
• The driver opens the door or takes off his/her seat belt
• DSTC is put in Sport mode (seepage 138)
• ACC has kept the vehicle at a standstillfor more than 2 minutes
• The engine has been switched off
• The brakes have overheated
The radar sensor and its limitations
In addition to being used by ACC, the radar sensor is also used by Distance Alert (seepage 155) and Collision Warning with FullAuto-brake and Pedestrian Detection (seepage 164). This sensor is designed to detectcars or larger vehicles driving in the samedirection as your vehicle, in the same lane.
WARNING
• If there is visible damage to the front grille or you suspect that the radarsensor may be damaged in any way,contact a trained and qualified Volvoservice technician as soon as possible.The radar sensor may only functionpartially (or not at all) if it is damagedor is not securely fastened in place.
• Accessories or other objects, such asextra headlights, must not be installedin front of the grille.
• Modification of the radar sensor couldmake its use illegal.
The radar sensor's capacity to detect vehi- cles ahead is impeded:
• if the radar sensor is obstructed and can- not detect other vehicles, for example inheavy rain, or if snow or other objects areobscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
• if the speed of vehicles ahead is signifi- cantly different from your own speed.
Situations where ACC may not function optimally
WARNING
•The radar sensor has a limited field of vision. In some situations it may detecta vehicle later than expected or notdetect other vehicles at all.
• If ACC is not functioning properly,cruise control 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 example a vehicle that suddenlyenters the lane between your vehicle andthe target vehicle.
Small vehicles, such as motorcycles, or vehicles not driving in the center of thelane may remain undetected.
In curves, the radar sensor may detect the wrong vehicle or lose sight of the tar-get vehicle.
WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic,weather and road conditions. The"Function" section provides informa-tion about limitations that the drivermust be aware of before using thisfeature.
• This system is designed to be a sup-plementary driving aid. It is not, how-ever, intended to replace the driver'sattention and judgement. The driver isresponsible for maintaining a safe dis-tance and speed and must intervene ifAdaptive Cruise Control does notmaintain a suitable speed or suitabledistance to the vehicle ahead.
• Maintenance of ACC components mayonly be performed by a trained andqualified Volvo technician.
WARNING
• Adaptive Cruise Control is not a colli- sion avoidance system. The driver isalways responsible for applying thebrakes if the system does not detectanother vehicle.
• Adaptive Cruise Control does not reactto people or animals, or small vehiclessuch as bicycles and motorcycles. Italso does not react to slow moving,parked or approaching vehicles, orstationary objects.
• Do not use Adaptive Cruise Control indemanding driving conditions such ascity driving or other heavy traffic situa-tions, in slippery conditions, whenthere is a great deal of water or slushon the road, during heavy rain orsnow, in poor visibility, on windingroads or on highway on- or off-ramps.
Fault tracing and actions
If the message Radar blocked See manualis displayed, this means that the radar signals from the sensor have been obstructed andthat a vehicle ahead cannot be detected. This, in turn, means that the functions of the ACC, Distance Alert, and Collision Warning

System with Auto-brake and Pedestrian Detection will not function.
The table lists possible causes for this mes-sage 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.
