Warning light, braking by driver required
Controls in steering wheel
Radar sensor in front grille
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

184 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. 192).
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. 210)) 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.

Adaptive Cruise Control – limitationsThe 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 detect avehicle later than expected or not detectother vehicles at all.
• If ACC is not functioning properly, cruisecontrol 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 examplea vehicle that suddenly enters the lanebetween your vehicle and the target vehicle.
Small vehicles, such as motorcycles, or vehi- cles not driving in the center of the lane mayremain undetected.
In curves, the radar sensor may detect the wrong vehicle or lose sight of the target vehi-cle.
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.

City Safety – troubleshooting
TroubleshootingIf Windscreen Sensors blocked appears in the
information display, this indicates that the City Safety ™ laser sensor is obstructed in some way
and cannot detect vehicles ahead of you, which means that the system is not functioning. However, this message will not be displayed in all situations in which the sensor is obstructed. Forthis reason, the driver must ensure that the areaof the windshield in front of the sensor is alwayskept clean. The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
CauseAction
The area of the windshield in front of the sensor isdirty or covered by ice orsnow.Clean the wind- shield or removethe ice/snow.
The laser sensor's field of view is obstructed.Remove the obstruction.
NOTE
If a crack, scratch or stone chip should occur in the section of the windshield in front thelaser sensor, contact a trained and qualifiedVolvo service technician to repair or replacethe windshield (see the illustration showingthe location of the sensor in City Safety –function (p. 202)). Failing to do so may result in reduced City Safety ™ functionality.
To help prevent limited or reduced functional- ity, please also observe the following:
• Volvo recommends that cracks, scratchesor stone chips on the windshield in front of the laser sensor
should not be
repaired; in such cases, the entire wind- shield should be replaced.
• Before the windshield is replaced, con-tact a Volvo retailer to ensure that thecorrect windshield is ordered and instal-led. If the wrong type of windshield is used, this may cause City Safety
™ to
function improperly or not at all. Volvo recommends the use of only GenuineVolvo Replacement Windshields.
• When replacing windshield wipers, usethe same type or ones approved by Volvo.
