Setting a time interval for PilotAssist
Pilot Assist can be set to different time intervals.
Different time intervals to thevehicle 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 ofapprox. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panelshows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval.
When only a steering wheel is shown, there isno vehicle ahead within a reasonable dis-tance.
Controls for setting a time interval59.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease orincrease the time interval.
>The distance indicator (3) shows the cur-rent time interval.
In order to follow the vehicle ahead as smoothlyas 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, thegreater 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 thecurrent 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 todetermine how Pilot Assist should maintain atime interval to the vehicle ahead. Settings aremade using the DRIVE MODE controls.

Select one of the following:
Eco - Pilot Assist will focus on providingoptimal fuel economy, which will increase thetime interval to the vehicle ahead.
Comfort - Pilot Assist will focus on followingthe set time interval to the vehicle ahead assmoothly as possible.
Dynamic - Pilot Assist will focus on follow-ing the set time interval to the vehicle aheadmore exactly, which could mean faster accel-eration and heavier braking.

...or...
–Press the ◀ button on the steering wheel (3).
>Pilot Assist is turned off and AdaptiveCruise Control will go into active mode.
WARNING
With Pilot Assist in standby mode, thedriver 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.

WARNING
When Pilot Assist follows another vehicle atspeeds over approx. 30 km/h (20 mph) andchanges target vehicle – from a moving vehi-cle to a stationary one – Pilot Assist willignore the stationary vehicle and insteadaccelerate to the stored speed.
The driver must then intervene and applythe brakes.
Automatic standby mode when switching
targets
Pilot Assist disengages and goes into standbymode 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.

Auto-hold braking with Pilot Assist
Pilot Assist has a special braking function inslow 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 steeringwheel keypad.
Pressing the accelerator pedal.
>Pilot Assist will resume following the vehi-cle ahead if it begins to move withinapprox. 6 seconds.
NOTE
Pilot Assist can keep the vehicle stationaryfor no more than 5 minutes – after that timethe parking brake is applied and the functionis deactivated.
The parking brake must be released beforePilot Assist can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivatedwhen 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 Rpositions
the driver puts Pilot Assist in standby mode.
Auto Activate Parking Brake
In certain situations, the parking brake will beapplied to keep the vehicle at a standstill.
This occurs if Pilot Assist is keeping the vehiclestationary 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.

City Safety™
City Safety can alert the driver with light, soundand 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 sensor69.
City Safety can help prevent a collision or lowerthe vehicle's speed at the point of impact.
City Safety is an aid intended to assist the driverif a collision with a pedestrian, large animal,cyclist or vehicle is imminent.
City Safety can help the driver avoid a collisionwhen 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 automaticallyapplying 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 anattempt to stop your vehicle immediately behindthe vehicle or object ahead.
City Safety is activated in situations in which thedriver 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 aspossible to help avoid unnecessary intervention.
Normally, the occupants of the vehicle will not beaware of City Safety except when the systemintervenes when a collision is imminent.

Cross Traffic Alert*
CTA81 is a supplementary driver support system
to BLIS82 that is intended to help the driverdetect vehicles crossing behind the vehiclewhile backing up.
CTA overview.
CTA supplements BLIS by detecting traffic cross-ing from the side, e.g. when backing out of aparking space.
CTA is primarily designed to detect vehicles, butin certain cases can also detect pedestrians orsmaller objects such as bicycles.
CTA is only active when the vehicle is movingbackward or if reverse gear is engaged.
If CTA detects that something is approachingyour vehicle from the side:
an audible signal will sound from either theleft or right speaker, depending on whichside of your vehicle the object is approachingfrom.
an icon will illuminate in the PAS83 graphicon the screen.
an icon will appear in the Park Assist Cam-era's Top view.
Illuminated CTA icon in the PAS graphic84 on thescreen.
