Automatic standby mode
Pilot Assist interacts with other systems, such asElectronic Stability Control. If any of these othersystems are not functioning properly, Pilot Assistwill automatically be deactivated.
WARNING
If this happens, the driver will be alerted by anaudible 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 standbymode if:
•the camera cannot detect the traffic lane'sside marker lines
•the vehicle ahead is not within a reasonable(detectable) distance
•the driver's hands are not on the steeringwheel
•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., wet snow or if heavy rain interferes withradar waves

Pilot Assist-2*
The Pilot Assist feature helps keep the vehicle inits current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
Function
Pilot Assist helps provide more relaxed driving onlong trips on highways or other major roads in aneven flow of traffic.
Function overview (generic illustration)
Windshield module containing the camera/radar sensor
Monitoring distance
Monitoring side marker lines
The driver sets the desired time interval to thevehicle ahead. Pilot Assist monitors that vehicleand the traffic lane's side market lines using the
camera and radar sensor mounted in the upper,center section of the windshield. It helps maintainthe set time interval by automatically adjustingspeed and by providing steering assistance tohelp keep your vehicle in the lane.
Pilot Assist's steering assistance is based onmonitoring the direction of the vehicle ahead andthe traffic lane's side marker lines. The driver canalways override Pilot Assist and steer the vehicleto e.g., change lanes, etc.
If the camera and radar sensor cannot detect thelane's side marker lines, Pilot Assist will tempo-rarily switch off the steering assistance until thelane's side marker lines become visible again andcan be detected. However, the function's speedand distance monitoring will continue to be acti-vated.
WARNING
Pilot Assist's steering assistance may switchon or off without warning.
The color of the steering wheelsymbol indicates the currentstatus of the steering assis-tance function:
WHITE: steering assistance isactive
GRAY (as in the illustration): steering assistanceis deactivated

Collision warning
Warning light in the windshield
Pilot Assist can exert brake force that is equiva-lent to approximately 40% of the vehicle's totalbraking capacity.
In situations requiring more brake force than PilotAssist can provide and if the driver does notapply the brakes, an audible signal and warninglight will illuminate in the windshield to alert thedriver to react.
NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

Prerequisites
The prerequisites for activating Pilot Assist are:
•The driver's seat belt must be buckled andthe 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 PilotAssist in standby mode (8).
2.Press the button (2) on the left-sidesteering wheel keypad.
>Pilot Assist will go into active mode andthe 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 to WHITE.
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 onestored 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 drivingconditions 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 PilotAssist 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.

DRIVER SUPPORT
* Option/accessory, for more information, see Introduction.310
•the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that PilotAssist has the following limitations:
•High curbs, barriers and temporary obsta-cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
•The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
•Pilot Assist does not "see" pedestrians,animals, etc.
•Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
Hands on the steering wheel
Pilot Assist only functions when the driver'shands are on the steering wheel, which is con-tinuously monitored by the system. If this is notthe case, the driver will be alerted by a text mes-sage in the instrument panel. If the driver's handsare not returned to the steering wheel, an audiblesignal will sound.
If the driver does not return his/her hands to thesteering wheel after the audible signal, Pilot
Assist will go into standby mode and must be
reactivated by pressing .

Time interval controls
Press to reduce the time interval to the vehi-cle ahead
Press to increase the time interval to thevehicle ahead
Distance indicator
In order to follow the vehicle ahead as smoothlyas possible, Pilot Assist allows the time interval tovary considerably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Pilot Assist increases the time intervalslightly.
•If Pilot Assist does not seem to react when itis put in active mode, this may be becausethe set time interval to the vehicle aheaddoes not allow an increase in speed.
•The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
WARNING
•Only use a time interval that is suitable incurrent traffic conditions.
•A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

Changing target vehicles andautomatic braking with PilotAssist-2
At certain speeds, Pilot Assist can change targetvehicles and automatically apply the brakes.
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta-tionary vehicle ahead
When Pilot Assist is actively following anothervehicle at speeds under 20 mph (30 km/h) andchanges targets from a moving vehicle to a sta-tionary one, the system will brake for the station-ary vehicle.
WARNING
If Pilot Assist changes targets from a movingvehicle to a stationary one at speeds above20 mph (30 km/h), the system will not reactto the stationary vehicle and will accelerate tothe previously set speed.
The driver must actively apply the brakes toslow/stop the vehicle.
Automatic standby mode when changing
targets
Pilot Assist disengages and goes into standbymode if:
•your vehicle's speed goes below approx.3 mph (5 km/h) and Pilot Assist cannotdetermine if the target object is a stationaryvehicle or some other type of object such asa speed bump, etc
•the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that Pilot Assistno longer has a target vehicle to follow
Auto-hold brake function
In 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, Pilot Assist will go into standby mode andthe auto-hold brake function will activate.

takes action. If the vehicle has slowed to avoidcolliding with the vehicle ahead, your speed willbe reduced to that vehicle's speed.
When auto-brake is triggered, the seat belt pre-tensioners may also be activated, see the article"Seat belts" for additional information.
Auto-braking can be cancelled if the driverpresses hard on the accelerator pedal.
When City Safety applies the brakes, the brakelights will illuminate.
When City Safety is triggered and applies thebrakes, a text message will be displayed in theinstrument panel.

City Safety warning level settings
City Safety is always activated but the function'swarning distance can be adjusted.
NOTE
City Safety cannot be turned off and activatesautomatically each time the engine/electricmotor is started.
Setting a warning level (distance)
The distance set for warnings determines thesystem'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 Topview.
2.Tap My CarIntelliSafeCity Safety.
3.Choose among Earlier, Normal or Later.
Begin by choosing Earlier. If too many warningsare given, change to Normal.
If the driver feels that warnings are given toooften, 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 exceptionalcircumstances, e.g., for a more dynamic drivingstyle.
WARNING
•No automatic system can be guaranteedto 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 beenselected, warnings may be perceived asbeing 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 aspossible, always using the setting Earlieris recommended.
NOTE
•Due to local traffic regulations in certainmarkets, RCW will not activate the rearturn signals. That part of the function willbe deactivated.
•The use of the rear turn signals will alsobe deactivated if the City Safety warninglevel is set at Later. See also the section"Setting a warning level (distance)" in thearticle "City Safety settings."
•If RCW detects a vehicle approachingfrom behind, the seat belt pretensioners
