Adaptive Cruise Control – introductionACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead. It is primarilyintended for use on long straight roads in steadytraffic, such as on highways and other mainroads.
When the driver has set the desired speed and the time interval to the vehicle ahead, ACC func-tions as follows:
• If there are no other vehicles in the laneahead of you, your vehicle will travel at theset speed.
• If ACC's radar sensor detects a slower mov-ing vehicle in the lane ahead, the system willadapt your vehicle's speed to help maintainthe set time interval to the vehicle ahead.When there are no longer slower movingvehicles ahead, your vehicle will accelerate toresume the set speed.
If ACC is switched off completely or in standbymode and your vehicle comes too close toanother vehicle ahead, the driver will be warnedby the Distance Alert system (see Distance Alert– introduction (p. 191)).
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.

Adaptive Cruise Control consists of:
• A cruise control system to maintain a set speed
• A system to maintain a set distance to thevehicle ahead, which is expressed as a timeinterval. For example, you can choose toremain approximately 2 seconds behind thevehicle ahead. The actual distance required

178 to maintain a 2-second interval will vary according the speed of the vehicles.
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.
The distance to the vehicle ahead (in the same lane) is monitored by a radar sensor. Your vehi-cle's speed is regulated by accelerating andbraking. The brakes may emit a sound when theyare being modulated by the adaptive cruise con-trol system. This is normal.
WARNING
The brake pedal moves when the adaptive cruise control system modulates the brakes.Do not rest your foot under the brake pedal.
The ACC system is designed to smoothly regu- late speed. However, the driver must apply thebrakes in situations that require immediate brak-ing. This applies when there are great differencesin speed between vehicles, or if the vehicle aheadbrakes suddenly.
WARNING
Due to limitations in the radar sensor, braking may occur unexpectedly or not at all, seeAdaptive Cruise Control – limitations (p. 186).
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) orif engine speed (rpm) becomes too low, ACC dis-engages (goes into standby mode) and will nolonger modulate the brakes. The driver will thenhave to maintain a safe distance to the vehicleahead.
WARNING
When Adaptive Cruise Control is in standby mode or is switched off completely, thebrakes will not be modulated automatically.The driver must assume full control over thevehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force that is equivalent to approximately 40% of thevehicle's total braking capacity. In situationsrequiring more brake force than ACC can provideand if the driver does not apply the brakes, anaudible signal from the Collision Warning systemwill sound and warning light will illuminate (see Collision warning * – function (p. 204)) in the
windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

Adaptive Cruise Control – setting speed
Setting a speedOnce ACC has been put in standby mode:
Controls and display
Put in active mode and set a speed (each additional press increases/decreases speedby 1 mph (approximately 2 km/h))
• Press 
 or  (4).
> The set speed, for example 60 mph (5), will be magnified for several seconds and the frame around the speed will change colors from  white  to green  to indicate that this
speed has been stored (set).
When this symbol has changed colorsfrom white  to green , ACC is in active
mode and the vehicle will maintain the
set speed.
This symbol indicates that you are approaching a vehicleahead. ACC will switch from maintain- ing a  set speed  to maintaining
a set  distance  from that vehi-
cle.
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 pressing the 
 or  buttons. Each time one of
these buttons is pressed, the vehicle's speed changes by 5 mph or 5 km/h. If the speed isincreased by pressing the accelerator pedal,the vehicle's speed when the button ispressed will be set.
• Press and hold one of these buttons toincrease/decrease the speed in 1-mph or 1-km/h increments. Release the button whenyou have reached the desired speed.
NOTE
•
If one of the Adaptive Cruise Control but- tons is pressed for more than approxi-mately one minute, ACC will be deacti-vated. The engine must then be switchedoff and restarted to reset ACC.
• In some situations Adaptive Cruise Con- trol cannot be put in active mode.

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 adjustment. Different time intervals can be selected and are shown in the instrument panel
2
 as 1–5 hori-
zontal bars. The greater the number of bars, the longer thetime interval. One bar repre-sents a time interval of approxi-
mately 1 second; 5 bars is approximately3 seconds.
To set/change a time interval:
• Press the 
/ buttons (3).
At low speeds, when the distance to the vehicle ahead is short, ACC increases the time intervalslightly. In order to follow the vehicle ahead assmoothly as possible, ACC allows the time inter-val to vary considerably in certain situations.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.
