–Activate the direction indicator. Use the left direction indicator in a car with the steering wheel on the left, or the rightdirection indicator in a car with the steeringwheel on the right.
> Overtaking assistance is started.
LimitationsWhen using Overtaking Assistance the driver should be prepared for sudden changes in condi-tions. In some conditions Overtaking Assistancecan cause unwanted acceleration. Some situations should be avoided for this rea- son. Examples of such situations are:
• the car is approaching an exit road in orderto turn off in the same direction that is nor-mally used for overtaking
• the vehicle in front slows before your car hasentered the overtaking lane
• traffic in the overtaking lane is slowing
• a car designed for right-hand traffic is beingdriven in a country with left-hand traffic (orvice versa).
Situations of this kind can be avoided by tempo-rarily setting ACC or Pilot Assist in standby mode.

Change of target and automatic braking with the Adaptive CruiseControl
In combination with automatic gearbox, the adaptive cruise control (Adaptive Cruise Control- ACC ) has functionality for change of targetand braking at certain speeds.
Change of target
If the target vehicle in front suddenly turns then there may be stationary traffic in front.
When the adaptive cruise control is following another vehicle at speeds below 30 km/h
(20 mph) and the target is changed from a mov- ing vehicle to a stationary vehicle, the adaptivecruise control will brake for the stationary vehicle.
WARNING
When the adaptive cruise control is following another vehicle at speeds in excess of
approx. 30 km/h (20 mph) and the target is changed from a moving vehicle to a stationaryvehicle, the adaptive cruise control will ignorethe stationary vehicle and instead select thestored speed.
• The driver must then intervene him/ herself and brake.
Automatic standby mode with change of target
The adaptive cruise control is disengaged and set in standby mode: • when the speed is below 5 km/h (3 mph) and the adaptive cruise control is uncertainwhether the target object is a stationary vehi-cle or some other object, such as a speedbump.
• when the speed is below 5 km/h (3 mph)and the vehicle ahead turns off so the adap-tive cruise control no longer has a vehicle tofollow.
Automatic brakingFor shorter stops in connection with inching inslow traffic or at traffic lights driving is automati-cally resumed if the stops do not exceed about3 seconds - if it takes longer before the car in

300 front starts moving again then the adaptive cruise control is set in standby mode with automaticbraking.
–The Adaptive Cruise Control is reactivated in one of the following ways:
• Press the steering wheel button
.
• Depress the accelerator pedal.
> The Adaptive Cruise Control resumes fol- lowing the vehicle ahead if it starts mov- ing forward within 6 seconds.
NOTE
ACC can keep the car stationary for a maxi- mum of 5 minutes. After this the parkingbrake is applied and adaptive cruise control isdisengaged. The parking brake must be released before the adaptive cruise control can be reactivated.
Cessation of automatic braking
In some situations, automatic braking ceases on reaching 0 km/h and Adaptive Cruise Control isset in standby mode. This means that the brakesare released and the car may start to roll - thedriver must therefore intervene and brake the carhimself/herself to keep it stationary. This may take place in the following situations:
• the driver puts his/her foot on the brakepedal
• the parking brake is applied
• the gear selector is moved to
P, N , or R posi-
tion
• the driver sets the adaptive cruise control inthe standby mode.
Automatic activation of parking brakeIn certain situations the parking brake is appliedto keep the car stationary. This takes place if the adaptive cruise control is holding the car stationary with the foot brake and: •the driver opens the door or takes off his/her seatbelt
• ACC has kept the car stationary for morethan approx. 5 minutes
• the brakes have overheated
• the engine is switched off.

Limitations of the adaptive cruise control *
The (Adaptive Cruise Control - ACC) may have limitations in certain situations.
Steep roads and/or heavy loadBear in mind that the adaptive cruise control is primarily intended for use when driving on levelroad surfaces. The function may have difficulty inkeeping the correct distance from the vehicleahead when driving on steep downhill slopes - inwhich case, be extra attentive and ready to brake.Do not use the adaptive cruise control with aheavy load or with a trailer connected to the car.
Miscellaneous
• Drive mode Off Road cannot be selected
when the adaptive cruise control is activated.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Pilot Assist *
Pilot Assist helps the driver to drive the car between the lane's side markings using steeringassistance as well as to maintain an even speed,combined with a preselected time interval to thevehicle ahead.
The Pilot Assist function gives more comfortable driving and a more relaxed driving experienceduring, for example, long journeys on motorwaysin even traffic flows.
The camera and radar unit measures the distance to the vehicle ahead and detects side markings 9
.
Camera and radar unit
Distance readers
Readers, side markings The driver selects the desired speed and a time interval to the vehicle ahead. Pilot Assist scansthe distance to the vehicle ahead and the lane'sside markings on the road surface using thecamera and radar unit. The preset time interval ismaintained with automatic speed adjustmentwhilst the steering assistance helps to positionthe car in the lane. Pilot Assist steering assistance takes into account the speed of the preceding car and thelane markings. The driver can at any time ignorethe Pilot Assist steering recommendation andsteer in another direction, e.g. to change lane oravoid an obstruction on the road. If Pilot Assist cannot interpret the lane unambig- uously, e.g. if the camera and radar unit does notsee the lane's side markings, Pilot Assist tempo-rarily deactivates steering assistance, butresumes it if the lane can be interpreted again -although the speed and distance control func-tions remain active.
NOTE
Pilot Assist steering assistance is deactivated and is resumed without prior warning.
The current status of steering assistance is indicated by thecolour of the steering wheel'ssymbol: • GREEN steering wheel indi- cates active steering assis-
tance • GREY steering wheel (as in illustration) indi- cates deactivated steering assistance.

WARNING
Pilot Assist is an aid which cannot handle all traffic, weather and road conditions. The driver must always be observant with regard to the prevailing traffic conditions andintervene if Pilot Assist does not provide suit-able steering assistance or maintain a suita-ble speed or suitable time interval. Read all the sections about this function in the owner's manual in order to learn about itslimitations, of which the driver should beaware before the function is used. Pilot Assist must only be used if there are clear lane lines painted on the road surfaceon each side of the lane. All other useinvolves increased risk of contact with sur-rounding obstacles that are not detected bythe function. The driver always bears responsibility for how the car is controlled as well as for maintainingthe correct distance and speed, even whenPilot Assist is being used.
Pilot Assist regulates the speed with acceleration and braking. It is normal for the brakes to emit alow sound when they are being used to adjustthe speed. Pilot Assist attempts to regulate the speed smoothly. In situations that demand sudden brak-ing the driver must brake himself/herself. Thisapplies in case of large speed differences or ifthe vehicle in front brakes suddenly. Due to the limitations of the camera and radar unit, brakingmay come unexpectedly or not at all. Pilot Assist aims to follow the vehicle ahead in the same lane at a time interval set by the driver.If the radar unit cannot see any vehicle in frontthen the car will instead maintain the speed setand stored by the driver. This also takes place ifthe speed of the vehicle ahead increases andexceeds the stored speed. The following applies for cars with automatic gearbox:
• Pilot Assist can follow another vehicle atspeeds from 0 km/h up to 200 km/h(125 mph).
• Pilot Assist can give steering assistance fromalmost stationary up to 140 km/h (87 mph).
The following applies for cars with manual gear-box: • Pilot Assist can follow another vehicle at speeds from 30 km/h (20 mph) up to200 km/h (125 mph).
• Pilot Assist can give steering assistance from30 km/h (20 mph) up to 140 km/h(87 mph).
WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver must intervene if the systemdoes not detect a vehicle in front. Pilot Assist does not brake for people, ani- mals, objects, small vehicles (e.g. cycles andmotorcycles), low trailers as well as oncoming,slow or stationary vehicles. Do not use Pilot Assist, for example, in city traffic, at junctions, on slippery surfaces, witha lot of water or slush on the road, in heavyrain/snow, in poor visibility, on winding roads,on slip roads, or with a trailer connected tothe car.
IMPORTANT
Maintenance of Pilot Assist components must only be performed at a workshop - an author-ised Volvo workshop is recommended.

Press
▶ (6).
> The
symbol changes to Pilot Assist
in standby mode (8).
2. Press the steering wheel button
(2).
> Pilot Assist is started and current speed is stored, which is shown with figures in the centre of the speedometer.
...or... With the adaptive cruise control started:
–Press ▶ (6).
> Pilot Assist is started.
Pilot Assist steering assistance is only active when the steeringwheel symbol (2) has changedfrom GREY to GREEN. Pilot Assist only regulates the time interval to the vehicle
ahead when the distance symbol shows a vehicle(1) above the steering wheel symbol.
At the same time a speed range is marked. The higher speed is the stored/selected speed and thelower speed is that of the vehi-cle ahead (target vehicle).
Hands on the steering wheelIn order for Pilot Assist to function, the driver must have his/her hands on the steering wheel.The system continually monitors this. If hands arenot detected on the steering wheel then a textmessage is shown, prompting the driver toactively steer the car. If this is not done, anacoustic warning signal will also be given. If that does not prompt the driver to put his/her hands on the steering wheel either, Pilot Assistchanges to standby mode. Following which, PilotAssist must be restarted with the steering wheel button
.
NOTE
Note that Pilot Assist only works when the driver has hands on the steering wheel.
