Introduction
Adaptive Cruise Control (ACC) is an optional system designed to assist the driver by main-taining a set speed or a set time interval tothe vehicle ahead. It is primarily intended foruse on long straight roads in steady traffic,such as on highways and other main roads. When the driver has set the desired speed and the time interval to the vehicle ahead,ACC functions as follows:
• If there are no other vehicles in the lane ahead of you, your vehicle will travel atthe set speed.
• If ACC's radar sensor detects a slowermoving vehicle in the lane ahead, the sys-tem will adapt your vehicle's speed tohelp maintain the set time interval to thevehicle ahead. When there are no longerslower moving vehicles ahead, your vehi-cle will accelerate to resume the setspeed.
If ACC is switched off completely or in standby mode and your vehicle comes tooclose to another vehicle ahead, the driver willbe warned by the Distance Alert system (seepage 169).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
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 165 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 156).
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):

Lane Departure Warning (LDW)
The illustration is generic
This function is designed to help reduce the risk of accidents in situations where the vehi- cle unintentionally leaves its lane and there isa risk of driving off the road or into the oppo-site lane. LDW uses the camera located at thecenter, upper edge of the windshield to moni-tor the road's/lane’s side marker lines. If thevehicle crosses a side marker line or theroad’s center dividing line, the driver will bealerted by an audible signal.
