Pilot Assist's steering assis- tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN. Pilot Assist will only regulate
the time interval to the vehicle ahead when the distance symbol shows a vehicle (1) over thesteering wheel symbol.
A speed interval will be marked at the same time. The higher speed is the set speed for your vehicle and thelower speed is the speed of thevehicle ahead (target vehicle).
Hands on the steering wheelPilot Assist only functions if the driver's hands are on the steering wheel. If Pilot Assist detectsthat the driver's hands are not on the steeringwheel, the driver will be instructed to activelysteer the vehicle by a text message and an audi-ble signal. If Pilot Assist still cannot detect the driver's hands on the steering wheel, the function will gointo standby mode. Pilot Assist must then be reactivated by pressing the
button on the
steering wheel.
NOTE
Note that the Pilot Assist function only works when the driver's hands are on the steeringwheel.

• The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
button on the
steering wheel, the vehicle's speed when the but- ton is pressed will be stored as the set speed. 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 transmission
Pilot Assist can follow another vehicle at speeds from a standstill up to 200 km/h (125 mph). The lowest speed that can be set for Pilot Assist is 30 km/h (20 mph). When following anothervehicle, ACC can monitor that vehicle's speedand slow your own vehicle down to a standstill,but it is not possible to set speeds lower than30 km/h (20 mph). The highest possible speed that can be set is200 km/h (125 mph).

Setting a time interval for PilotAssist
Pilot Assist can be set to different time intervals.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, the longerthe time interval. One bar rep-resents an interval of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panel shows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval. When only a steering wheel is shown, there is no vehicle ahead within a reasonable dis-tance.

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 63
, 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.

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.

Recommended maintenance for thecamera/radar sensor
In order for the camera/radar sensor to function properly, the area of the windshield in front of theunit must be kept free of dirt, ice, snow, etc. andshould be washed regularly with water and carwashing detergent.
NOTE
Dirt, ice and snow covering the camera and radar unit reduce their function and can makemeasurement impossible. It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response.

City Safety
™
City Safety can alert the driver with light, sound and pulsations in the brake pedal to help thedriver detect pedestrians, cyclists, large animalsand vehicles that appear suddenly – the vehiclewill then attempt to automatically brake if thedriver does not act within a reasonable amountof time.
Location of the camera and radar sensor 71
.
City Safety can help prevent a collision or lower the vehicle's speed at the point of impact. City Safety is an aid intended to assist the driver if a collision with a pedestrian, large animal,cyclist or vehicle is imminent. City Safety can help the driver avoid a collision when e.g. driving in stop-and-go traffic, when changes in the traffic ahead and driver distractioncould lead to an incident. The function assists the driver by automatically applying the brakes if there is an imminent risk ofa collision and the driver does not react in time bybraking and/or steering away. City Safety activates a brief, forceful braking in an attempt to stop your vehicle immediately behindthe vehicle or object ahead. City Safety is activated in situations in which the driver should have applied the brakes much ear-lier, which means that the system will not be ableto assist the driver in all situations. City Safety is designed to be activated as late as possible to help avoid unnecessary intervention. Normally, the occupants of the vehicle will not be aware of City Safety except when the systemintervenes when a collision is imminent.

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.

Rear Collision Warning
The Rear Collision Warning (RCW) function can help the driver avoid rear-end collisions fromvehicles approaching from behind.
RCW is automatically activated each time the engine is started. RCW can warn the driver of a potential collision with vehicles approaching from behind by rapidlyflashing the turn signals. If, at a speed below 30 km/h (20 mph), the RCW function detects that the car is in danger of beinghit from behind, the seatbelt tensioners may ten-sion the front seatbelts and activate the WhiplashProtection System safety system. Immediately before a collision from behind, RCW may also activate the foot brake in order toreduce the forward acceleration of the car duringthe collision. However, the brakes will only beapplied if your vehicle is stationary. The brakeswill be immediately released if the acceleratorpedal is depressed.

Rear Collision Warning limitations
In some situations, it may be difficult for RCW to warn the driver of a collision risk.
This may be the case if:
• the vehicle approaching from the rear is detected at a late stage
• the vehicle approaching from the rearchanges lanes at a late stage
• the vehicle approaching from the rear is mov-ing at a speed above 80 km/h (50 mph)
• a trailer, bicycle holder or similar is con-nected to the vehicle's electrical system - theRCW function will then be automaticallydeactivated.
NOTE
In certain markets RCW does
not warn with
the direction indicators due to local traffic regulations – in such cases, that part of thefunction is deactivated.
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.

CTA 87
functionality may be reduced in certain
situations.
CTA does not function optimally in all situations and has certain limitations. The CTA sensors, forexample, cannot "see" through other parkedvehicles or objects blocking the vehicle. Below are a few examples of situations in which CTA's field of vision may be initially limited andapproaching vehicles may therefore not bedetected until they are very close to your vehicle:
The vehicle is parked very far into a parking space.
In a diagonal parking space, CTA may be completely "blind" on one side of your vehicle.
