To temporarily deactivate Adaptive Cruise Controland put it in standby mode:
–Press the button on the steering wheel(2).
>The symbol in the instrument panelchanges color from WHITE to GRAY andthe set speed in the center of the speed-ometer will change from BEIGE to GRAY.

WARNING
If Adaptive Cruise Control is in standbymode, the driver must intervene and regu-late both speed and distance to the vehicleahead.
If the vehicle comes too close to a vehicleahead when Adaptive Cruise Control is instandby mode, the driver is instead warnedof the short distance by the Distance Alertfunction.

Standby mode due to action by the driver
Adaptive Cruise Control will be temporarily deac-tivated and put in standby mode if:
the brakes are applied
the gear selector is moved to N
the vehicle is driven faster than the setspeed for more than 1 minute
Temporarily increasing speed using the accelera-tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Adaptive Cruise Control is dependent on othersystems, such as Electronic Stability Control
(ESC46). If any of these other systems stopsworking, Adaptive Cruise Control will automati-cally switch off.

WARNING
With automatic standby mode, the driver iswarned by an acoustic signal and a messageon the instrument panel.
The driver must then regulate vehiclespeed, apply the brakes if necessary, andmaintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standbymode if:
your vehicle's speed goes below 5 km/h(3 mph) and ACC cannot determine if thevehicle ahead is stationary or if it is anotherobject, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatACC no longer has a vehicle to follow.
the driver opens the door.
the driver unbuckles the seat belt.
the engine speed (rpm) is too low/high.
one or more of the wheels lose traction.
the brake temperature is high.
the parking brake is applied.
the camera/radar sensor is covered by snowor heavy rain (the camera lens/radar wavesare blocked)

Adaptive Cruise Control is primarily intended tobe driven on flat roads. The function may not beable to maintain the correct time interval to thevehicle ahead when driving down steep hills. Thedriver should be extra attentive and prepared toapply the brakes.
Do not use Adaptive Cruise Control if thevehicle is carrying a heavy load or towing atrailer.

Other limitations
The Off Road drive mode cannot beselected if Adaptive Cruise Control is acti-vated.

NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

Pilot Assist
Pilot Assist helps the driver keep the vehicle inthe current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.

How Pilot Assist works
The Pilot Assist function is primarily intended foruse on highways and other major roads where itcan help provide a more comfortable and relaxingdriving experience.
The camera/radar sensor monitors the distance to thevehicle ahead and detects lane markings56.
Camera and radar sensor
Distance monitor
Lane marker line monitors
The driver sets the desired speed and distance tothe vehicle ahead. Pilot Assist monitors the dis-tance to the vehicle ahead and the traffic lane'sside markers using the camera and radar sensor.The system maintains the set time interval to thevehicle ahead by automatically adjusting yourvehicle's speed and keeps your vehicle in its laneby providing steering assistance.
Pilot Assist's steering assistance is based onmonitoring the direction of the vehicle ahead andthe traffic lane's side marker lines. The driver canoverride Pilot Assist's steering recommendationsat any time and steer in another direction, e.g. tochange lanes or avoid obstacles on the road.
If the camera/radar sensor cannot detect thelane's side marker lines or if Pilot Assist is unablefor some other reason to clearly interpret thelane, Pilot Assist will temporarily deactivate steer-ing assistance until it can once again interpretthe lane markings. However, the speed and dis-tance warnings will remain active.

WARNING
Pilot Assist is deactivated automatically andresumes working without prior notice.
The color of the steering wheelsymbol indicates the currentstatus of steering assistance:
• GREEN indicates that steer-ing assistance is active
• GRAY (as shown in illustra-tion) indicates that steering assistance is deacti-vated.
56Note: This illustration is general and details may vary depending on model.

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.

Standby mode due to action by the driver
Pilot Assist will be temporarily deactivated andput in standby mode if:
the brakes are applied.
the gear selector is moved to N
a turn signal is used for more than 1 minute.
the vehicle is driven faster than the setspeed for more than 1 minute
Temporarily increasing speed using the accelera-tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
When the turn signals are used, Pilot Assist'ssteering assistance will be temporarily deacti-vated. When the turn signal is switched off, steer-ing assistance will be automatically reactivated ifthe traffic lane's side markings can still bedetected.

Automatic standby mode
Pilot Assist is dependent on other systems, such
as Electronic Stability Control (ESC60). If any ofthese other systems stops working, Pilot Assistwill automatically switch off.
WARNING
With automatic standby mode, the driver iswarned by an acoustic signal and a messageon the instrument panel.
The driver must then regulate vehiclespeed, apply the brakes if necessary, andmaintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standbymode if, e.g.:
the driver opens the door.
the brake temperature is high.
the driver's hands are not on the steeringwheel.
the parking brake is applied.
the engine speed (rpm) is too low/high.
the driver unbuckles the seat belt.
one or more of the wheels lose traction.
the camera/radar sensor is covered by snowor heavy rain (the camera lens/radar wavesare blocked)
your vehicle's speed goes below 5 km/h(3 mph) and Pilot Assist cannot determine ifthe vehicle ahead is stationary or if it isanother object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatPilot Assist no longer has a vehicle to follow.

Pilot Assist limitations
Pilot Assist functionality may be reduced in cer-tain situations.
Pilot Assist is a driver support function designedto simplify driving and assist the driver in manysituations. However, the driver is always responsi-ble for maintaining a suitable distance to vehiclesor objects around it and ensuring that the vehicleis correctly positioned in the traffic lane.

WARNING
In some situations, Pilot Assist may have trou-ble helping the driver properly or may bedeactivated automatically – we advise againstusing Pilot Assist in such cases. Examples ofsuch situations include:
the lane markings are worn, missing orcross each other.
lane division is unclear, for example, whenthe lanes divide or merge or at exits orwhen there are multiple sets of markings.
edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
the lane is narrow or winding.
the lane contains ridges or holes.
weather conditions are poor, e.g. rain,snow or fog or slush or reduced visibilitywith poor light conditions, backlighting,wet road surface, etc.
The driver should also note that Pilot Assisthas the following limitations:
High curbs, roadside barriers, temporaryobstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane mark-ings, with a subsequent risk of contactbetween the vehicle and such obstacles.
The driver is responsible for ensuring thatthe vehicle maintains a suitable distancefrom such obstacles.
The camera and radar sensors do nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects that completely or partiallyblock the route.
Pilot Assist does not "see" pedestrians,animals, etc.
The recommended steering input is lim-ited in force, which means that it cannotalways help the driver to steer and keepthe vehicle within the lane.
In vehicles equipped with SensusNavigation*, the function is able to useinformation from map data, which couldcause variations in performance.
Pilot Assist is switched off if the powersteering is working with reduced power -e.g. during cooling due to overheating(see section "Speed-dependent steeringforce").
The driver can always correct or adjust steeringassistance provided by Pilot Assist by turning thesteering wheel to the desired position.
