NOTE
Before CC can be activated, the vehicle'sspeed must be at least 20 mph (30 km/h).This is also the lowest speed that can be set.

Activating CC (putting it in active mode
and setting a speed)
–With the symbol displayed (CC is in
standby mode), press the button (2) onthe left-side steering wheel keypad.
>This puts CC in active mode and willmaintain the vehicle's current speed.

Changing Cruise Control speed
Changing a set speed
Function buttons and symbols (generic illustration)
–Change a set speed by pressing the (1)or — (3) buttons briefly or by pressing andholding them:
•Press briefly: changes speed in+/– 5 mph (+/– 5 km/h) increments.Each press changes the vehicle's speedby +/– 5 mph (+/– 5 km/h).
•Press and hold: changes the speed+/– 1 mph (+/– 1 km/h) at a time.Release the button when the set speedindicator (4)/(6) has moved to the desiredspeed.
If speed is increased by pressing the accelerator
pedal before the button is pressed, the vehi-cle's speed when the button is pressed will
become the set speed assuming that the accel-erator pedal is still depressed when the button ispressed.
A temporary increase in speed, such as whenpassing another vehicle, does not affect the CCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released. Alwaysobserve posted speed limits.

Engine braking instead of applying the
brakes
CC regulates speed by applying the brakeslightly. To avoid a loss of speed when drivingdown hills, use the engine braking functioninstead of letting the CC apply the brakes. In thissituation, the driver can temporarily deactivate theCC braking function.
To do so:
–Press the accelerator pedal approx. halfwaydown and release it.
>CC will automatically deactivate the auto-matic brake function and will then onlyuse the engine braking function.

Distance Alert*
Distance Alert is a function that alerts the driverif the time interval to the vehicle ahead is tooshort.
Distance Alert is active at speeds above approxi-mately 20 mph (30 km/h) and only reacts to avehicle ahead that is driving in the same direc-tion. No information is provided for vehicles driv-ing toward you, moving very slowly, or at a stand-still.
Warning light (generic illustration)
A warning light in the windshield glows steadily ifyour vehicle is closer to the one ahead than theset time interval.

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.

NOTE
Distance Alert only monitors distance to thevehicle ahead while Adaptive Cruise Control isin standby mode or off.

WARNING
Distance Alert only indicates the distance tothe vehicle ahead. It does not affect thespeed of your vehicle.
Head-up-display *
Distance Alert symbol in the windshield (generic illustra-tion)
In vehicle is equipped with the head-up display*,the symbol in the windshield will only appear ifthe distance to the vehicle ahead is shorter thanthe preset value. However, the Show DriverSupport In Head-Up Display function has tobe activated in the Settings menu. See the article"Head-up display" for additional information.

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.

Distance Alert* limitations
Distance Alert uses the same radar sensor asAdaptive Cruise Control* and has several limita-tions.

WARNING
•The radar sensor has a limited field ofvision. In some situations it may detect avehicle later than expected or not detectother vehicles at all.
•The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
•The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
•Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
•Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see.
WARNING
•Poor weather or winding roads can affectthe radar sensor's capacity to detect vehi-cles ahead.
•A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorterdistance than the one that has been setor not illuminating at all.
•High speeds may also result in the warn-ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.
For additional information, see also the article"Radar sensor limitations."

Adaptive Cruise Control (ACC)*
ACC is an optional system designed to assistthe driver by maintaining a set speed or a settime interval to the vehicle ahead.
ACC helps provide more relaxed driving on longtrips on highways or other major roads in a rela-tively even flow of traffic.
The camera and radar sensor monitor the distance tothe vehicle ahead (generic illustration - certain detailsmay vary from model to model)
The driver sets that desired speed and time inter-val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed.
ACC is designed to follow a vehicle ahead in thesame lane and maintain a time interval to that

Collision warning
Warning light in the windshield
Adaptive Cruise Control can exert brake forcethat is equivalent to approximately 40% of thevehicle's total braking capacity.
In situations requiring more brake force thanACC can provide and if the driver does not applythe brakes, an audible signal from the City Safetysystem will sound and warning light will illuminatein 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.

WARNING
Adaptive Cruise Control only warns of vehiclesdetected by the radar sensor. In some casesthere may be no warning or the warning maybe delayed. The driver should always apply thebrakes when necessary.

Head-up-display *
A flashing light alerts the driver
A flashing icon will appear in the head-up displayto alert the driver of a collision risk.

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.

Starting and activating Adaptive
Cruise Control (ACC)*
ACC must first be put in active mode before itcan be started in order to regulate speed or aset time interval to the vehicle ahead.

Starting ACC (putting it in standby
mode)
Function buttons and symbols
–Press ◀ (2) or ▶ (3) to scroll to the ACC
() function. The symbol (4) will be dis-played in the instrument panel.
>The symbol indicates that ACC has beenstarted and is in standby mode. Instandby mode, the vehicle will not main-tain a set speed or a time interval to thevehicle ahead.

DRIVER SUPPORT
* Option/accessory, for more information, see Introduction.288
Setting an Adaptive Cruise Controltime interval
ACC makes it possible to set various time inter-vals to the vehicle ahead.
Different time intervals to thevehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val. One bar between the vehi-cles represents a time interval of approximately1 second; 5 bars is approximately 3 seconds.
The same symbol appears if Distance Alert isactivated.
•If the symbol shows two vehicle's, ACC isactively following the vehicle ahead (a targetvehicle).
•If only one vehicle is displayed, ACC is notactively following another vehicle.

Changing a time interval
Controls for setting a time interval
Reduce the time interval
Increase the time interval
Distance/time indicator
–Press buttons (1) or (2) to reduce orincrease the time interval.
>The distance/time indicator (3) shows thecurrent time interval.
In order to follow the vehicle ahead as smoothlyas possible, ACC allows the time interval to varyconsiderably in certain situations. At low speeds,when the distance to the vehicle ahead is short,ACC increases the time interval slightly.
•If ACC does not seem to react when it is putin active mode, this may be because the set
time interval to the vehicle ahead does notallow an increase in speed.
•The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
•Only use time intervals permitted by localtraffic regulations.

WARNING
•Only use a time interval that is suitable incurrent traffic conditions.
•A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

WARNING
If ACC changes targets from a moving vehicleto a stationary one at speeds above 20 mph(30 km/h), the system will not react to thestationary vehicle and will accelerate to thepreviously set speed.
The driver must actively apply the brakes toslow/stop the vehicle.

Automatic standby mode when changing
targets
ACC disengages and goes into standby mode if:
•your vehicle's speed goes below approx.3 mph (5 km/h) and ACC cannot determineif the target object is a stationary vehicle orsome other type of object such as a speedbump, etc
•the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow.

Auto-hold brake function
In slow-moving, stop-and-go traffic or when stop-ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, ACC will go into standby mode and theauto-hold brake function will activate.
–The driver will then have to reactivate ACC inone of the following ways:
•Press the button on the left-sidesteering wheel keypad.
•Press the accelerator pedal.
>ACC will resume following the vehicleahead (target vehicle) if it begins to movewithin approx. 6 seconds.
NOTE
ACC can keep the vehicle at a standstill forup to 5 minutes, after which the parking brakewill be set and ACC will go into standbymode.
The parking brake has to be released beforeACC can be reactivated.

Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivatedwhen the vehicle is at a standstill and ACC will gointo standby mode.
This means that the brakes will be released andthe vehicle can begin to roll.
The driver must actively apply the brakes to keepthe vehicle at a standstill.
This can occur in the following situations:
•the driver presses the brake pedal
•the parking brake is set
•the gear selector is moved to the P, N or Rpositions
•the driver puts ACC in standby mode.
Automatically setting the parking brake
In certain situations, the parking brake is setautomatically to help keep the vehicle at a stand-still.
This occurs if ACC keeps the vehicle at a stand-still with the brakes and:
•the driver unbuckles the seat belt or opensthe door
•ACC has kept the vehicle at a standstill formore than approx. 5 minutes
•the brakes overheat
•the engine is turned off.
