Adaptive Cruise Control regulates speed byaccelerating and braking. It is normal for thebrakes to emit a slight sound when they arebeing used to adjust speed.
Adaptive Cruise Control always attempts to regu-late speed smoothly. The driver must apply thebrakes in situations requiring immediate braking.For example, when there are great differences inspeed between vehicles or if the vehicle aheadbrakes suddenly. Due to limitations in the radarsensor, braking may occur unexpectedly or not atall.
Adaptive Cruise Control is designed to follow avehicle ahead in the same lane and maintain atime interval to that vehicle set by the driver. If theradar sensor does not detect a vehicle ahead, itwill instead maintain the speed set by the driver.This will also happen if the speed of the vehicleahead exceeds the set speed for your vehicle.
Adaptive Cruise Control can follow anothervehicle at speeds from a standstill up to200 km/h (125 mph).

WARNING
Adaptive Cruise Control is not a collisionavoidance system. The driver is alwaysresponsible and must intervene if the sys-tem fails to detect a vehicle ahead.
Adaptive Cruise Control does not brakefor people or animals and does not brakefor small vehicles, such as bikes andmotorcycles. Similarly, it does not brakefor low trailers, oncoming, slow-moving orstationary vehicles and objects.
Do not use Adaptive Cruise Control indemanding situations, such as in city traf-fic, at intersections, on slippery surfaces,with a lot of water or slush on the road, inheavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.

CAUTION
Maintenance of Adaptive Cruise Control com-ponents may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.

Adaptive Cruise Control andcollision warning
Adaptive Cruise Control can alert the driver if thedistance to the vehicle ahead suddenly decrea-ses to an unsafe distance.
Collision warning audible signal and symbol39.
Acoustic collision warning signal
Collision warning symbol
Camera/radar sensor distance monitoring
Adaptive Cruise Control utilizes approx. 40% ofthe vehicle's braking capacity. If a situationrequires more braking force than the AdaptiveCruise Control can provide, and if the driver doesnot apply the brakes, a warning light and audible
warning signal will be activated to alert the driverthat immediate action is required.

WARNING
Adaptive Cruise Control only issues a warningfor vehicles detected by its radar unit – thus, awarning may come after a delay or not at all.
Never wait for a warning. Apply thebrakes when necessary.

WARNING
When Adaptive Cruise Control follows anothervehicle at speeds over approx. 30 km/h(20 mph) and changes target vehicle – from amoving vehicle to a stationary one – AdaptiveCruise Control will ignore the stationary vehi-cle and instead accelerate to the storedspeed.
The driver must then intervene and applythe brakes.

Automatic standby mode when switching
targets
Adaptive Cruise Control will be disabled and gointo standby mode:
if your vehicle's speed goes below 5 km/h(3 mph) and Adaptive Cruise Control cannotdetermine if the target object is a stationaryvehicle or another object, e.g. a speed bump.
if your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatAdaptive Cruise Control no longer has a vehi-cle to follow.

Automatic braking with AdaptiveCruise Control
The Adaptive cruise control (ACC51) has a spe-cial brake function in slow traffic and while sta-tionary.
Braking function in slow traffic and at a
standstill
In slow-moving, stop-and-go traffic or when stop-ped at a traffic light, driving will resume automati-cally if the vehicle is stopped for less thanapprox. 3 seconds. If it takes more than 3 sec-onds for the vehicle ahead to begin moving again,Adaptive Cruise Control will go into standbymode and the Auto-hold brake function will acti-vate.
–Adaptive Cruise Control can be reactivated inone of the following ways:
Pressing the button on the steeringwheel keypad.
Pressing the accelerator pedal.
>Adaptive Cruise Control will resume fol-lowing the vehicle ahead if it begins tomove within approx. 6 seconds.
NOTE
ACC can keep the vehicle stationary for nomore than 5 minutes – after that time theparking brake is applied and Adaptive CruiseControl is deactivated.
The parking brake must be released beforeAdaptive Cruise Control 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 AdaptiveCruise Control will go into standby mode. Thismeans that the brakes will be released and thevehicle could begin to roll. The driver mustactively apply the brakes to keep the vehicle sta-tionary.
This can occur if:
the driver depresses the brake pedal
the parking brake is applied
the gear selector is moved to the P, N or Rpositions
the driver puts Adaptive Cruise Control instandby mode.

Auto Activate Parking Brake
In certain situations, the parking brake will beapplied to keep the vehicle at a standstill.

WARNING
The Pilot Assist function is supplementarydriver support intended to facilitate driv-ing and help make it safer – it cannothandle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
Pilot Assist should only be used if thereare clear lane lines painted on each sideof the lane. All other use will increase therisk of contact with nearby obstacles thatcannot be detected by the functions.
Pilot Assist is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theproper position within the lane, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
NOTE
Depending on market, this function may beeither Standard or Optional.
Pilot Assist regulates speed by accelerating andbraking. It is normal for the brakes to emit a slightsound when they are being used to adjust speed.
Pilot Assist attempts to smoothly regulate speed.The driver must apply the brakes in situationsrequiring immediate braking. For example, whenthere are great differences in speed betweenvehicles or if the vehicle ahead brakes suddenly.Due to limitations in the camera and radar sen-sor, braking may occur unexpectedly or not at all.
Pilot Assist is designed to follow a vehicle aheadin the same lane and maintain a time interval tothat vehicle set by the driver. If the radar sensordoes not detect a vehicle ahead, it will insteadmaintain the speed set by the driver. This will alsohappen if the speed of the vehicle aheadexceeds the set speed for your vehicle.
Pilot Assist can follow another vehicle atspeeds from a standstill up to 200 km/h(125 mph).
Pilot Assist can provide steering assistancefrom near-stationary speeds up to 140 km/h(87 mph).
WARNING
Pilot Assist is not a collision avoidancesystem. The driver must intervene if thesystem fails to detect a vehicle ahead.
Pilot Assist does not brake for people,animals, objects, small vehicles (e.g.cycles and motorcycles), low trailers aswell as oncoming, slow or stationary vehi-cles.
Do not use Pilot Assist in demanding sit-uations, such as in city traffic, at intersec-tions, on slippery surfaces, with a lot ofwater or slush on the road, in heavy rain/snow, in poor visibility, on winding roads,on highway on- or off-ramps, or with atrailer connected to the vehicle.

CAUTION
Maintenance of the integrated components inPilot Assist may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.

In curves and forks in the road
Pilot Assist is designed to interact with the driver.The driver should never wait for steering assis-tance from Pilot Assist, but instead should alwaysbe ready to increase his or her own steeringefforts, particularly in curves.

Setting a time interval for PilotAssist
Pilot Assist can be set to different time intervals.
Different time intervals to thevehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, the longerthe time interval. One bar rep-resents an interval ofapprox. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.

NOTE
When the symbol in the instrument panelshows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval.
When only a steering wheel is shown, there isno vehicle ahead within a reasonable dis-tance.
Controls for setting a time interval59.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease orincrease the time interval.
>The distance indicator (3) shows the cur-rent time interval.
In order to follow the vehicle ahead as smoothlyas possible, Pilot Assist allows the time interval tovary considerably in certain situations. For exam-ple, at low speeds and short distances to thevehicle ahead, Pilot Assist increases the timeinterval slightly.
NOTE
The greater the vehicles' speed, thegreater the distance between them for aset time interval.
Only use the time intervals permitted bylocal traffic regulations.
If Pilot Assist does not seem to respondwith a speed increase when activated, itmay be because the time interval to thevehicle ahead is shorter than the set timeinterval.

WARNING
Only use a time interval suitable for thecurrent traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Setting how Pilot Assist should
maintain distance * to the vehicle ahead
The driver can choose different drive modes todetermine how Pilot Assist should maintain atime interval to the vehicle ahead. Settings aremade using the DRIVE MODE controls.
