> 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.

Deactivating/activating the Pilot Assist*
Pilot Assist can be temporarily deactivated so that it is set in the standby mode and can bereactivated later.
Deactivating and setting Pilot Assist in
standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
To temporarily switch off Pilot Assist and set it in standby mode:
–Press the steering wheel button (2).
> Pilot Assist is set in standby mode - the symbol (8) in the driver display changes colour from WHITE to GREY and thestored speed in the centre of the speed-ometer changes from BEIGE to GREY.
...or...
–Press ◀ (3).
> Pilot Assist is switched off and changes to the adaptive cruise control in active mode.
In standby mode, the driver is no longer given anydriver steering recommendations and must con-trol both speed and distance him/herself. When Pilot Assist is in standby mode and the car drives too close to a vehicle ahead, the driver iswarned about the short distance by the DistanceWarning function instead (see reference to theheading "Distance Warning" at the end of thissection).
Standby mode on driver intervention
Pilot Assist is temporarily deactivated and set in standby mode if:
• the foot brake is used
• the gear selector is moved to
N position.
• the direction indicators are used for longerthan 1 minute .
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
• the clutch pedal is depressed forapprox. 1 minute - applies to cars with man-ual gearbox.
A temporary increase in speed with the accelera-tor pedal, e.g. during overtaking, does not affectthe setting - the car returns to the last storedspeed when the accelerator pedal is released. When the direction indicators are used, PilotAssist steering assistance is temporarily disen-gaged. When this is no longer the case, steeringassistance is automatically reactivated if thelane's side markings can still be detected.

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.

City Safety
City Safety uses visual, haptic and acoustic sig- nals to alert the driver of any pedestrians,cyclists, large animals and vehicles that appear.The car then brakes automatically unless thedriver him/herself acts within a reasonable time.
Location of the radar unit 14
.
City Safety can prevent a collision or reduce colli- sion speed. City Safety is an aid to assist a driver who is at risk of colliding with a pedestrian, large animal,cyclist or a vehicle. The City Safety function can help the driver to avoid a collision when driving in queues, e.g.when changes in the traffic ahead, combined witha lapse in attention, could lead to an incident. The function helps the driver by automaticallybraking the car in the event of an imminent riskof collision if the driver does not react in time bybraking and/or swerving. City Safety activates a short, sharp braking proce- dure, normally stopping the car just behind thevehicle in front. For most drivers this is well out-side normal driving style and may be perceived asuncomfortable. City Safety is activated in situations where the driver should have started braking earlier, whichis why it cannot help the driver in every situation. City Safety is designed to be activated as late as possible in order to avoid unnecessary interven-tion. The driver or passengers are not normally aware of City Safety - it only intervenes in a situationwhere a collision is immediately imminent. City Safety can avoid a collision with a vehicle ahead or a bicycle by reducing the speed of thecar by up to 50 km/h (30 mph). For a pedestrian,City Safety can reduce speed by up to 45 km/h(28 mph). If the speed difference is greater than 50 km/h (30 mph) or 45 km/h (28 mph) respectively, CitySafety's automatic braking cannot prevent a colli-sion but it can mitigate the consequences of acollision.In the event of a risk of a collision with a largeanimal, City Safety can reduce the car's speed byup to 15 km/h (9 mph). The braking function forlarge animals is primarily intended to reduce thecollision force at high speeds. Braking is mosteffective at speeds above 70 km/h (43 mph) andless effective at low speeds.
