.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease or increase the time interval.
> The distance indicator (3) shows the cur-
rent time interval.
In order to follow the vehicle ahead as smoothly as 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, the greater 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 the current 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 to determine how Pilot Assist should maintain atime interval to the vehicle ahead. Settings are made using the DRIVE MODE controls. Select one of the following:
•
Eco - Pilot Assist will focus on providing
optimal fuel economy, which will increase the time interval to the vehicle ahead.
•
Comfort - Pilot Assist will focus on following
the set time interval to the vehicle ahead as smoothly as possible.
•
Dynamic - Pilot Assist will focus on follow-
ing the set time interval to the vehicle ahead more exactly, which could mean faster accel-eration and heavier braking.
For more information, see "Drive modes". Additional information is provided in the sections "Managing Cruise Control speed" and "ECOdrive mode".

Deactivating/reactivating PilotAssist
Pilot Assist can be temporarily put into standby mode and then reactivated.
Deactivating and putting Pilot Assist in standby mode
Note: This illustration is general and details may vary depending on model.
To temporarily deactivate Pilot Assist and put it in standby mode:
–Press the button on the steering wheel
(2).
> Pilot Assist goes into standby mode - the symbol (8) in the instrument panel changes color from WHITE to GRAY andthe set speed in the center of the speed-ometer will change from BEIGE to GRAY. ...or...
–Press the
◀ button on the steering wheel (3).
> Pilot Assist is turned off and Adaptive Cruise Control will go into active mode.
WARNING
• With Pilot Assist in standby mode, the driver must intervene and steer and regu-late both speed and distance to the vehi-cle ahead.
• If the vehicle comes too close to a vehicleahead when Pilot Assist is in standbymode, the driver is instead warned of theshort distance by the Distance Alert func-tion.
Standby mode due to action by the driver
Pilot Assist will be temporarily deactivated and put 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 to the set speed when the accelerator pedal isreleased. When the turn signals are used, Pilot Assist's steering 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 (ESC65
). If any of
these other systems stops working, Pilot Assist will automatically switch off.
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a messageon the instrument panel. • The driver must then regulate vehicle speed, 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 steering wheel.
• 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.Reactivating Pilot Assist from standby
mode
Note: This illustration is general and details may vary depending on model.
To reactivate Pilot Assist:
–Press the button on the steering wheel
(1).
> Speed will be set to the most recently stored speed.
WARNING
A noticeable increase in speed may follow when the speed is resumed with the
steering wheel button.

Passing assistance with Pilot Assist
Pilot Assist can assist the driver when passing other vehicles.
How passing assistance worksWhen Pilot Assist is following another vehicle and you indicate that you intend to pass that vehicle by using the turn signal 66
, Pilot Assist will
begin accelerating toward the vehicle ahead before your vehicle has moved into the passing
lane. The function will then delay a speed reduction to avoid early braking as your vehicle approaches aslower-moving vehicle. The function remains active until your vehicle has passed the other vehicle.
WARNING
Please note that this function can be acti- vated in more situations than just passinganother vehicle, such as when a direction indi-cator is used to indicate a lane change orbefore exiting to another road – the vehiclewill then briefly accelerate.

Requirements for passing assistanceIn order to activate passing assistance:
• your vehicle must be following a vehicle ahead (target vehicle)
• your vehicle's
current speed must be
at least 70 km/h (43 mph)
• the set speed
for Pilot Assist must be high
enough to safely pass another vehicle.
Starting parking assistanceTo start passing assistance:
–Turn on the left turn signal.
> Passing assistance will start.
Related information
• Pilot Assist (p. 305)
Passing assistance with Pilot Assistlimitations
Passing assistance functionality may be reduced in certain situations.
WARNING
The driver should be aware that if conditions suddenly change when using Parking Assis-tance, the function may implement an unde-sired acceleration in certain conditions. Some situations should be avoided, e.g. if: • the vehicle is approaching an exit in the same direction as passing would normallyoccur
• the vehicle ahead slows before your vehi-cle has had time to switch to the passinglane
• traffic in the passing lane slows down
• a vehicle for right-hand traffic is driven ina country with left-hand traffic (or viceversa).
Situations of this type can be avoided by tempo-rarily putting Pilot Assist in standby mode.

Switching target vehicles with PilotAssist
At certain speeds, models with automatic trans-
missions and Pilot Assist can switch target vehi-cles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When Pilot Assist is actively following another vehicle at speeds under 30 km/h (20 mph) and
switches targets from a moving vehicle to a sta-
tionary vehicle, Pilot Assist will brake for the sta-tionary vehicle.
WARNING
When Pilot Assist follows another vehicle at speeds over approx. 30 km/h (20 mph) and
changes target vehicle – from a moving vehi- cle to a stationary one – Pilot Assist will ignore the stationary vehicle and instead
accelerate to the stored speed.
• The driver must then intervene and apply the brakes.
Automatic standby mode when switching
targets
Pilot Assist disengages and goes into standby mode if:
• your vehicle's speed goes below 5 km/h(3 mph) and Pilot Assist cannot determine ifthe target object is a stationary vehicle oranother 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.

Automatic braking with Pilot Assist
Pilot Assist has a special braking function in slow traffic and at a standstill.
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,Pilot Assist will go into standby mode and theAuto-hold brake function will activate.
–Pilot Assist can be reactivated by:
• Pressing the
button on the steering
wheel keypad.
• Pressing the accelerator pedal.
> Pilot Assist will resume following the vehi- cle ahead if it begins to move within approx. 6 seconds.
NOTE
Pilot Assist can keep the vehicle stationary for no more than 5 minutes – after that timethe parking brake is applied and the functionis deactivated. The parking brake must be released before Pilot Assist can be reactivated.

Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated when the vehicle is at a standstill and Pilot Assistwill go into standby mode. This means that thebrakes will be released and the vehicle couldbegin to roll. The driver must actively apply thebrakes to keep the vehicle stationary. 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 R
positions
• the driver puts Pilot Assist in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will be applied to keep the vehicle at a standstill. This occurs if Pilot Assist is keeping the vehicle stationary using the brakes and:
• the driver opens the door or unbuckleshis/her seat belt
• Pilot Assist has kept the vehicle at a stand-still for more than approx. 5 minutes
• the brakes overheat
• the driver switches off the engine manually.

Pilot Assist limitations
Pilot Assist functionality may be reduced in cer- tain situations.
Pilot Assist is a driver support function designed to 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 or cross 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 Assist has the following limitations: • High curbs, roadside barriers, temporary obstacles (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.

WARNING
•The City Safety function is supplementary driver support intended to help improvedriving safety – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
• The City Safety auto-brake function canprevent a collision or reduce collisionspeed, but to ensure full brake perform-ance the driver should always depress thebrake pedal – even when the car auto-brakes.
• The warning and steering assistance areonly activated if there is a high risk of col-lision – you must therefore never wait forthe collision warning or City Safety tointervene.
• Warnings and brake interventions forpedestrians and cyclists are disengagedat vehicle speeds over 80 km/h(50 mph).
• City Safety does not activate auto-brakingintervention during heavy acceleration.
• City Safety 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 theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
• The driver is advised to read all sections in the Owner's Manual that relate to CitySafety to learn about factors such as itslimitations and what the driver should beaware of before using the system (seethe list of links for all subsections).

City Safety parameters and sub-functions
City Safety can help avoid a collision with a vehi- cle, cyclist or large animal ahead by reducing thevehicle's speed using its automatic braking func-tion. If the difference in speed is greater than the speeds specified below, the City Safety auto-brake function cannot prevent a collision, but itcan help mitigate its effects.
Vehicles
City Safety can help prevent a collision with a vehicle ahead by reducing your vehicle's speedby up to 60 km/h (37 mph).
Cyclists
City Safety can help prevent a collision with a cyclist ahead by reducing your vehicle's speed byup to 50 km/h (30 mph).
Pedestrians
City Safety can help prevent a collision with a pedestrian ahead by reducing your vehicle'sspeed by up to 45 km/h (28 mph).

Large animals
If there is a risk of colliding with a large animal, City Safety can help reduce your vehicle's speedby up to 15 km/h (9 mph). The braking function for large animals is primarily intended to mitigate the force of a collision athigher speeds. Braking is most effective atspeeds above 70 km/h (43 mph) and less effec-tive at lower speeds.

Acoustic collision warning signal
Collision warning symbol
Camera/radar sensor distance monitoring City Safety carries out three steps in the follow- ing order:
1. Collision warning
2. Brake assistance
3. Auto-brakeDescriptions of what happens in these three steps are provided below.
1 - Collision warning
The driver is first alerted to the risk of an immi- nent collision. City Safety can detect pedestrians, cyclists or vehicles that are stationary, are moving in thesame direction as your vehicle and are ahead ofyour vehicle. City Safety can also detect pedes-trians, cyclists or large animals that are crossingthe road in front of your vehicle. If there is a risk of a collision with a pedestrian, large animal, cyclist or another vehicle, or with avehicle described in the section "City Safety incrossing traffic", the driver will be alerted withlight, sound and pulsations in the brake pedal. Atlower speeds, during hard braking or if the accel-erator pedal is pressed, the brake pedal pulsationwarning will not be given. The intensity of thebrake pedal pulsations varies according to thevehicle's speed.
2 - Brake assistance
If the risk of a collision increases after the colli- sion warning, brake support will be activated. If the system determines that the pressure the driver is exerting on the brake pedal is insufficientto prevent the collision, brake support willincrease pressure.

3 - Auto-brake
The automatic braking function is activated at the last moment. If the driver has not taken evasive action by this stage and a collision is imminent, the automaticbraking function will be triggered. This occurswhether or not the driver is pressing the brakepedal. Full braking force will be applied to reducethe speed at impact or reduced braking effect willbe applied if this is sufficient to avoid the colli-sion. The seat belt tensioners may be activated along with the automatic braking function. See "Seatbelt tensioners" for more information. In certain situations, auto-braking may begin with a limited braking force before applying full brak- ing force. If City Safety has prevented a collision, the vehi- cle will be kept at a standstill until the drivertakes action. If the vehicle has slowed to avoidcolliding with a slower-moving vehicle ahead, yourspeed will be reduced to that vehicle's speed. Auto-braking can always be cancelled if the driver presses hard on the accelerator pedal.
NOTE
When City Safety activates the brakes, the brake lights come on.
When City Safety applies the brakes, a text mes- sage will appear in the instrument panel to notifythe driver that the function is/was activated.
WARNING
City Safety may not be used to change how the driver operates the vehicle. The drivermust not only rely on City Safety to brake thevehicle.

Setting a warning distance for CitySafety
City Safety is always active, but the function's warning distance can be adjusted.
NOTE
The City Safety function cannot be deacti- vated. It is activated automatically each timethe engine/electric motor is started.
The alert distance determines the sensitivity of the system and regulates the distance at whichthe light, sound and brake pulsations will be acti-vated. To select warning distance:
1. Select
SettingsMy CarIntelliSafe in
the center display's Top view.
2. Under
City Safety Warning, tap Late,Normal or Early to set the desired warning
distance.
If the driver feels that the
Early setting is giving
too many warnings or finds them irritating, the
Normal or Late warning distance settings can
be selected instead. If the driver feels that the warnings are too fre- quent and distracting, the warning distance canbe reduced. This will reduce the total number ofwarnings, but it will also result in City Safety pro-viding warnings at a later stage.

DRIVER SUPPORT
}}
333
The
Late warning distance setting should there-
fore only be used in exceptional cases, such as when a more dynamic driving style is preferred.
WARNING
• No automatic system can guarantee 100% correct function in all situations.You should therefore never test use ofCity Safety in the direction of people, ani-mals or vehicles – this could lead tosevere damage, serious personal injury oreven death.
• City Safety warns the driver if there is arisk of collision, but the function cannotreduce the driver's reaction time.
• Even if the warning distance has been set to
Early, warnings may be perceived as
late in certain situations – e.g. when there are large speed differences or if the vehi-cle ahead suddenly brakes heavily.
• With the warning distance set to
Early,
warnings come further in advance. This may cause the warnings to come morefrequently than with warning distance
Normal, but is recommended since it can
make City Safety more effective.
NOTE
The warning with direction indicators for Rear Collision Warning is deactivated if the colli-sion warning distance in the City Safety func- tion is set to the lowest level "
Late".
The seat belt tensioning and braking func- tions remain active.

Detecting obstacles with City Safety City Safety can detect vehicles, cyclists, large animals and pedestrians.
VehiclesCity Safety detects most types of vehicles that are either stationary, moving in the same direc-tion as your vehicle or those described in "CitySafety in crossing traffic". For City Safety to be able to detect a vehicle in the dark, its headlights and taillights must be onand clearly visible.
Cyclists
Optimal examples of what City Safety would interpret to be a cyclist: clear body and bicycle shapes.
For optimal performance, the system's function for cyclist detection needs the clearest possibleinformation about the contours of the bicycle andof the cyclist's head, arm, shoulders, legs, torso
