Adaptive Cruise Control – setting time interval
Setting a time interval
Controls and display
Decrease/increase time interval
The set time interval to vehicles ahead can be increased by pressing
and decreased by
pressing
. The current time interval is
shown briefly in the display following adjust- ment. Different time intervals canbe selected and are shown in the instrument panel
3
as 1–5
horizontal bars. The greater the number of bars, thelonger the time interval. Onebar represents a time interval
of approximately 1 second; 5 bars is approxi-mately 3 seconds.
To set/change a time interval:
• Press the
/ buttons (3).
At low speeds, when the distance to the vehi- cle ahead is short, ACC increases the timeinterval slightly. In order to follow the vehicleahead as smoothly as possible, ACC allowsthe time interval to vary considerably in cer-tain situations.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driverlimited reaction time if an unexpectedsituation occurs in traffic.

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 system. If this system is not function-ing properly, ACC will switch off automati-cally. 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)
• the wheels lose traction
• brake temperature is high
• the radar sensor is obstructed by, forexample, 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.

Adaptive Cruise Control – passing another vehicle
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).

Adaptive Cruise Control (ACC) – Queue Assist
Queue Assist is an added ACC feature that is linked to your vehicle's automatic transmis-sion.
IntroductionQueue Assist is an added ACC feature that islinked 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 ismoving 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):
• 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 Parking brake –general information (p. 268)).
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
• The stability system is put in Sport mode(see Stability system – operation (p. 176))
• ACC has kept the vehicle at a standstillfor 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 samedirection as your vehicle, in the same lane.
The radar sensor and its limitationsIn addition to being used by the AdaptiveCruise Control (ACC), the radar sensor is alsoused by Distance Alert (see Distance Alert –introduction (p. 198)) and Collision Warningwith Full Auto-brake and Pedestrian Detec-tion (see Collision warning – introduction(p. 209)).
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 in heavy 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.

Adaptive Cruise Control – limitations
The 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 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.

Adaptive Cruise Control – troubleshooting
If the message Radar blocked See manualis displayed, this means that the radar signalsfrom the sensor have been obstructed and that 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 PedestrianDetection 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.
