WARNING
At speeds above 20 mph (30 km/h), if ACC
changes targets from a moving vehicle to a stationary one, the system will not react to the
stationary vehicle and will accelerate to the previously set speed. The driver must actively apply the brakes to slow/stop the vehicle.
Automatic standby mode when changing targets
ACC disengages and goes into standby mode if:
• your vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determineif the target object is a stationary vehicle orsome other type of object such as a speedbump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow.
Auto-hold brake functionIn slow-moving, stop-and-go traffic or when stop-ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, ACC will go into standby mode and theauto-hold brake function will activate.
–The driver will then have to reactivate ACC in one of the following ways:
• Press the
button on the left-side
steering wheel keypad.
• Press the accelerator pedal.
> ACC will resume following the vehicle ahead (target vehicle) if it begins to move within approx. 6 seconds.
NOTE
ACC can keep the vehicle at a standstill for up to 5 minutes, after which the parking brakewill be set and ACC will go into standbymode. The parking brake has to be released before ACC 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 ACC will gointo standby mode. This means that the brakes will be released and the vehicle can begin to roll. The driver must actively apply the brakes to keep the vehicle at a standstill. This can occur in the following situations: • the driver presses the brake pedal
• the parking brake is set •
the gear selector is moved to the
P, N or R
positions
• the driver puts ACC in standby mode.
Automatically setting the parking brakeIn certain situations, the parking brake is set automatically to help keep the vehicle at a stand-still. This occurs if ACC keeps the vehicle at a stand- still with the brakes and:
• the driver unbuckles the seat belt or opensthe door
• ACC has kept the vehicle at a standstill formore than approx. 5 minutes
• the brakes overheat
• the engine is turned off.

Prerequisites
The prerequisites for activating Pilot Assist are:• The driver's seat belt must be buckled and the driver's door must be closed.
• There must be a vehicle ahead (a target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least9 mph (15 km/h).
With ACC in standby mode: 1. Tap
▶ (6).
> The symbol
will change to Pilot
Assist in standby mode (8).
2. Press the
button (2) on the left-side
steering wheel keypad.
> Pilot Assist will go into active mode and the current speed will be stored and dis- played in the center of the speedometer. or
If Adaptive Cruise Control has been started:
–Tap ▶ (6).
> Pilot Assist will start.
Pilot Assist's steering assis- tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN.
And Pilot Assist will only regulate the time inter- val to the vehicle ahead when a vehicle symbol(1) is displayed above the steering wheel. At the same time, a speedinterval will be marked. The higher speed is the one stored by the driver and thelower one is the speed of thevehicle ahead (target vehicle).WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle. Do not use Pilot Assist in demanding driving conditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps. In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.

* Option/accessory.291
In standby mode, the driver will have to regulate the vehicle's speed and the distance to the vehi-cle ahead. When Pilot Assist is in standby mode and your vehicle comes too close to another vehicle, thedriver will be alerted by the Distance Alert func-tion.
Standby mode due to action by the driver
Pilot Assist is temporarily deactivated and put in standby mode if:
• the brakes are applied
• The gear selector is moved to
N
• the turn signals are used for more than1 minute
• the vehicle is driven faster than the setspeed for more than 1 minute.
A temporary increase in speed, such as whenpassing another vehicle, does not affect the PilotAssist set speed. The vehicle will return to the setspeed when the accelerator pedal is released. When the turn signals are used, Pilot Assist's steering function will be temporarily deactivated.When this is no longer the case, the steeringfunction will reactivate if the traffic lane's sidemarker lines can still be detected.
Automatic standby mode
Pilot Assist interacts with other systems, such as Electronic Stability Control. If any of these other systems are not functioning properly, Pilot Assistwill automatically be deactivated.
WARNING
If this happens, the driver will be alerted by an audible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
Pilot Assist switches automatically to standby mode if: • the vehicle's speed is below approx. 3 mph(5 km/h) and Pilot Assist cannot determine ifa vehicle ahead is a stationary vehicle or anobject.
• the vehicle's speed is below approx. 3 mph(5 km/h) and the vehicle ahead turns so thatPilot Assist no longer has a vehicle to follow(target vehicle).
• the driver's hands are not on the steeringwheel
• the driver's door is opened
• the driver unbuckles the seat belt
• engine speed (rpm) is too high/low
• the wheels lose traction
• brake temperature is too high
• the parking brake is set •
The camera lens/radar sensor is covered bye.g., snow or if heavy rain interferes withradar wavesReactivating Pilot Assist from standby
mode

City Safety warning level settings
City Safety is always activated but the function's warning distance can be adjusted.
NOTE
City Safety cannot be turned off and activates automatically each time the engine is started.
Setting a warning level (distance)
The distance set for warnings determines the system's responsiveness and sets the distance atwhich visual, audible and tangible (haptic) warn-ings will be triggered. To do so:1. Tap
Settings in the center display's Top
view.
2. Tap
My CarIntelliSafeCity Safety
Warning.
3. Choose among
Earlier, Normal or Later.
Begin by choosing
Earlier. If too many warnings
are given, change to Normal.
If the driver feels that warnings are given too often, the warning level can be lowered. Thismeans that warnings will be provided later, result-ing in fewer warnings being given. The setting
Later should only used in exceptional
circumstances, e.g., for a more dynamic driving style.
WARNING
• No automatic system can be guaranteed to function 100% correctly in all situa-tions. For that reason, never test CitySafety by driving toward a person orobject. This could result in serious injuryor death.
• Even if the setting
Earlier has been
selected, warnings may be perceived as being given late, e.g., if the difference inspeed is great or if the vehicle aheadbrakes suddenly.
• City Safety can provide a warning for apotential collision but it can never shortenthe driver's reaction time.
• To help make City Safety as effective as possible, always using the setting
Earlieris recommended.
NOTE
•
Due to local traffic regulations in certain markets, Rear Collision Warning (RCW) will
not activate the rear turn signals.
That part of the function will be deacti- vated.
• The use of the rear turn signals will alsobe deactivated if the City Safety warning level is set at
Later. See also the section

Detecting obstructions 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 the arti-cle "City Safety in crossing traffic." In order for City Safety to detect a vehicle in darkness, its headlights and taillights must be onand clearly visible.
Cyclists
Optimal example of what the system considers to be a cyclist: clear body/bike contours
To help function optimally, City Safety's function for cyclist detection needs clear informationabout the bike itself and the rider's head, arms, shoulders, legs, the upper and lower parts of thebody and a cyclist's normal pattern of movement.
• If major parts of the cyclist's body are notvisible to the camera, the system cannotdetect the cyclist.
• The cyclist must be an adult riding a bikeintended for an adult.
WARNING
City Safety is designed to be a supplementary driving aid and cannot detect all cyclists in allsituations, such as:
• a partially obscured cyclist.
• a cyclist whose clothing prevents a clear view of the person's body contours.
• a cyclist transporting a large object.
The driver is always responsible for operating the vehicle in a safe manner.

DRIVER SUPPORT
316
Rear Collision Warning (RCW)The
Rear Collision Warning (RCW) function
can help the driver avoid rear-end collisions.
RCW is activated automatically each time the engine is started. RCW can warn the driver of a vehicle approach- ing yours from behind by rapidly flashing yourturn signals. RCW is only activated when a vehicle is rapidly approaching your vehicle from behind. At speeds below 20 mph (30 km/h), if RCW determines that your vehicle is at risk of a rear-end collision, the front seat belt pretensionersand the Whiplash Protection System are acti-vated. Just prior to the collision, the brakes are also applied to help reduce your vehicle's forwardmovement if and when the collision occurs. How-ever, this can only happen if your vehicle is sta-tionary. The brakes will be released immediately if the accelerator pedal is pressed.
NOTE
• Due to local traffic regulations in certain markets, Rear Collision Warning (RCW) will
not activate the rear turn signals.
That part of the function will be deacti- vated.
• The use of the rear turn signals will alsobe deactivated if the City Safety warning level is set at
Later. See also the section
"Setting a warning level (distance)" in the article "City Safety settings."
• If RCW detects a vehicle approachingfrom behind, the seat belt pretensionersand Whiplash Protection System will beactivated.
LimitationsIn some circumstances, it may be difficult for RCW to help the driver if there is a risk of a colli-sion, such as: •If the vehicle approaching from the rear is detected at a late stage
• If the vehicle approaching from the rearchanges lanes at a late stage
• If the vehicle approaching from the rear ismoving at a speed above approx. 50 mph(80 km/h)

Brake functions
The vehicle's standard braking features are aug- mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parking brake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill. These systems include: • Auto-hold brakes
• Hill Start Assist
• Braking assist after a collision
• Hill Descent Control
