WARNING
Adaptive Cruise Control only warns of vehicles detected by the radar sensor, seepage 155. 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.

When this symbol has changed col- ors from
white to green , ACC is in
active mode and the vehicle will
maintain the set speed.
This symbol indicates that you are approaching a vehi-cle ahead. ACC will switch from main- taining a set speed to main-
taining a set distance from
that vehicle.
When this happens, a speed range will be indicated on
the speedometer: The higher speed (the cur-
rently set speed (5)) will be marked in green.
The lower speed in the range is the speed of
the vehicle ahead.
Changing the set speed
• After a speed has been set, it can be increased or decreased by briefly press- ing the
or buttons. Each time one
of these buttons is pressed, the vehicle's speed changes by 3 mph(approximately 5 km/h). If the speed isincreased by pressing the accelerator pedal, the vehicle's speed when the but-ton is pressed will be set.
• Press and hold one of the buttons toincrease/decrease the speed by 1 mph(approximately 1 km/h) at a time. Releasethe button when you have reached thedesired speed.
NOTE
•If one of the Adaptive Cruise Control buttons is pressed for more thanapproximately one minute, ACC will bedeactivated. The engine must then beswitched off and restarted to resetACC.
• In some situations Adaptive CruiseControl cannot be put in active mode.
Cruise control Unavailable is shown
in the display, see page 157.
Setting a time intervalThe 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.

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

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.

Introduction
Distance Alert is part of Adaptive Cruise Con- trol and is a function that provides informa-tion about the time interval to the vehicleahead. Distance Alert is active at speeds above approximately 18 mph (30 km/h). Time inter-val information is only given for a vehicle thatis driving ahead of your vehicle in the samedirection. No information is provided for vehi-cles driving toward you, moving very slowly,or at a standstill.
Amber warning light 1
.
An amber warning light in the windshield glows steadily if your vehicle is closer to theone ahead than the set time interval.
NOTE
Distance Alert only monitors distance to the vehicle ahead while Adaptive CruiseControl is in standby mode or off.
WARNING
Distance Alert only indicates the distance to the vehicle ahead. It does not affect thespeed of your vehicle.
Operation
Press the button in the center instrument panel to switch this function on or off. Theindicator light in the button illuminates whenthe function is on. Depending on the optional equipmentselected, there may not be room for a Dis-tance Alert button in the center console. Inthis case, the function is controlled throughthe menu system. Press

Five different time intervals can be selected and areshown in the display as 1–5horizontal bars. The greaterthe number of bars, thelonger the time interval. Onebar represents approximately
1 second to the vehicle ahead; 5 bars isapproximately 3 seconds.
NOTE
• The higher your vehicle’s speed, the greater the distance to the vehicleahead, measured in feet (meters), for agiven time interval.
• The set time interval is also used byAdaptive Cruise Control, seepage 150.
WARNING
Only use a time interval that is suitable in current traffic conditions.
Limitations
Distance Alert uses the same radar sensor used by Adaptive Cruise Control and the Col-lision Warning system. See page 155 for
more information on the radar sensor’s limita-tions.
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.
WARNING
• Bad weather or winding roads may affect the radar sensor’s capacity todetect vehicles ahead.
• The size of the vehicle ahead, such asa motorcycle, may also make it difficultto detect. This may result in the warn-ing light illuminating at a shorter dis-tance than the one that has been set,or that the light will not come on at all.
