–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

Change of target and automatic braking with Pilot Assist *
In combination with automatic gearbox, Pilot Assist has functionality for change of target and braking at certain speeds.
Change of target
If the target vehicle in front suddenly turns then there may be stationary traffic in front.
When Pilot Assist is following another vehicle at speeds below 30 km/h (20 mph) and changes
target from a moving to a stationary vehicle, Pilot Assist will slow down for the stationary vehicle.
WARNING
When Pilot Assist 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 stationary vehicle, PilotAssist will ignore the stationary vehicle andinstead select the stored speed.
• The driver must then intervene him/ herself and brake.
Automatic standby mode with change of target
Pilot Assist is disengaged and set in standby mode: •when the speed is below 5 km/h (3 mph) and Pilot Assist is uncertain whether the tar-get object is a stationary vehicle or someother object, e.g. a speed bump.
• when the speed is below 5 km/h (3 mph)and the vehicle in front turns off so the PilotAssist no longer has a vehicle to follow.
Automatic brakingFor shorter stops in connection with inching for-ward in slow traffic or at traffic lights, driving isautomatically resumed if the stops do not exceedabout 3 seconds - if it takes longer before thecar in front starts moving again then the PilotAssist is set in standby mode with automaticbraking.
–Pilot Assist is reactivated in the following way:
• Press the steering wheel button
.
• Depress the accelerator pedal.
> Pilot Assist resumes following the vehicle ahead if it starts moving forward within 6 seconds.
NOTE
Pilot Assist can hold the car stationary for a maximum of 5 minutes - then the parkingbrake is applied and the function is disen-gaged. Before Pilot Assist can be reactivated, the parking brake must be released.

IMPORTANT
In certain situations, Pilot Assist steering assistance may have difficulty helping thedriver in the right way or it may be automati-cally deactivated - in which case, the use ofPilot Assist is not recommended. Examples ofsuch situations may be that: •the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits or inthe event of 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 impaired viewwith poor light conditions, back-lighting,wet road surface etc.
The driver should also note that Pilot Assisthas the following limitations: • High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane
markings, with a subsequent risk of con- tact between the car and such obstacles.The driver must ensure him/herself thatthe car is at a suitable distance from suchobstacles.
• The camera and radar sensor does nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects which completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is forcelimited, which means that it cannotalways help the driver to steer and keepthe car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed byPilot Assist and can turn the steering wheel tothe desired position.
Steep roads and/or heavy loadBear in mind that Pilot Assist is primarilyintended for use when driving on level road surfa-ces. The function may have difficulty in keepingthe correct distance from the vehicle ahead whendriving on steep downhill slopes - in which case,be extra attentive and ready to brake. Do not usePilot Assist with a heavy load or with a trailer con-nected to the car.
Miscellaneous
•Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Auto Brake
The automatic brake function is activated last. If in this situation the driver has not yet started to take evasive action and the risk of collision isimminent then the automatic braking function isdeployed - this takes place irrespective ofwhether or not the driver brakes. Braking thentakes place with full brake force in order toreduce collision speed, or with limited brake forceif it is sufficient to avoid a collision. In connection with automatic braking the seatbelt tensioner may also be activated. For more infor-mation see the "Seatbelt tensioner" section. In some situations, the action of Auto-brake may begin with light braking and then progress to fullbrake action. When City Safety has prevented a collision with a stationary object, the car remains stationary inanticipation of positive action by the driver. If thecar has been braked to avoid collision with aslower vehicle in front, its speed is reduced tomatch that of the vehicle in front.
NOTE
On cars with manual gearbox, the engine stops when the Auto-brake function has stop-ped the car, unless the driver has managed todepress the clutch pedal beforehand.
The driver can always interrupt a braking inter- vention by firmly depressing the acceleratorpedal.
NOTE
When City Safety™ brakes, the brake lights
come on.
When City Safety is activated and brakes the vehicle, the driver display shows a text messageto the effect that the function is/has been active.
WARNING
City Safety must not be used as an excuse for the driver to change his/her driving style. Ifthe driver relies solely on City Safety to do thebraking, there might be a risk of a collisionsooner or later.

Setting the warning distance for City Safety
City Safety is always activated, but it is possible to select the warning distance for the function.
NOTE
The City Safety function cannot be deacti- vated. It is activated automatically when theengine/electric operation is started andremains switched on until the engine/electricoperation is switched off.
The warning distance determines the sensitivity of the system and regulates the distance atwhich the visual, acoustic and haptic warningsshall be triggered. 1. Tap on
Settings in top view in the centre
display.
2. Press
My CarIntelliSafe.
3. Under
City Safety Warning, select Late,Normal or Early to set the desired warning
distance.
If the
Early setting produces too many warnings,
which could be perceived as irritating in certain situations, then use the
Normal or Late warning
distance. If warnings are perceived as being too frequent or disturbing then the warning distance can bereduced. This would lead to the system warning

has the opportunity to avoid a collision via a steering manoeuvre. However, if City Safety anticipates that an evasive manoeuvre is not possible due to traffic in anadjacent lane, the function can assist the driverby automatically starting to brake at an earlierstage.
WARNING
City Safety's ability to anticipate a certain sit- uation is an aid, and does not work in all driv-ing situations or traffic, weather and road con-ditions. The driver always bears ultimate responsibility for ensuring that the vehicle is driven safelyand that applicable laws and road traffic regu-lations are followed.

Limitations of City Safety
The City Safety function may have limitations in certain situations.
Surroundings
Low objects
Low-hanging objects, e.g. a flag/pennant for pro- jecting load, or accessories such as auxiliarylamps and bull bars that are higher than the bon-net limit the function.
Skidding
On slippery road surfaces the braking distance is extended, which may reduce the capacity of CitySafety to avoid a collision. In such situations, theanti-lock brakes and the stability control ESC willgive the best possible braking force with main-tained stability.
Oncoming light
The visual warning signal in the windscreen may be difficult to notice in the event of strong sun-light, reflections, when sunglasses are beingworn or if the driver is not looking straight ahead.
Heat
In the event of high passenger compartment temperature caused by e.g. strong sunlight, thevisual warning signal in the windscreen may betemporarily disengaged.
The camera and radar unit's field of view
The camera's field of vision is limited, which is why pedestrians, large animals, cyclists and vehi- cles in some situations cannot be detected, orthey are detected later than anticipated. Dirty vehicles may be detected later than others and if it is dark, motorcycles may be detected lateor not at all. If a text message in the driver display indicates that the camera and radar unit is obstructed, CitySafety may be unable to detect pedestrians, largeanimals, cyclists, vehicles or road lines ahead ofthe car. This means that the functionality of CitySafety may be reduced. However, an error message is not shown in all situations where the windscreen sensors areobstructed. The driver must therefore take care tokeep the area of windscreen in front of the cam-era and radar unit clear.
IMPORTANT
Maintenance and replacement of City Safety components must only be performed by aworkshop - an authorised Volvo workshop isrecommended.
Driver intervention

Park Assist Pilot *
Active parking assistance (Park Assist Pilot - PAP) helps the driver to park in or leave a park-ing space.
PAP checks first if a space is sufficiently big and thereafter helps the driver to turn the steeringwheel and manoeuvre the car into the space. The centre display indicates with symbols, graph- ics and text the various operations to be carriedout and when to do so.
NOTE
The PAP function measures the space and steers the car - the driver's task is to:
• keep a close watch around the car
• follow the instructions in the centre dis-play
• change gear (reverse/forward)
• control and maintain a safe speed
• brake and stop.
