Standby mode due to action by the driver
Pilot Assist will be temporarily deactivated andput 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 tothe set speed when the accelerator pedal isreleased.
When the turn signals are used, Pilot Assist'ssteering 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 (ESC56). If any ofthese other systems stops working, Pilot Assistwill automatically switch off.
WARNING
With automatic standby mode, the driver iswarned by an acoustic signal and a messageon the instrument panel.
The driver must then regulate vehiclespeed, 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 steeringwheel.
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 varydepending on model.
To reactivate Pilot Assist:
–Press the button on the steering wheel(1).

Passing assistance functionality may be reducedin certain situations.
WARNING
The driver should be aware that if conditionssuddenly 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 thesame 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.

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.

Cross Traffic Alert*
CTA77 is a supplementary driver support system
to BLIS78 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 PAS79 graphicon the screen.
an icon will appear in the Park Assist Cam-era's Top view.

Park Assist*
The Park Assist function can help the driverwhen maneuvering in tight spaces by indicatingdistances to obstacles using audible signals andgraphics in the center display.
Display view showing obstacle zones and sensor sec-tors.
The center display shows an overview of the vehi-cle in relation to objects that have been detected.
The marked sector indicates where the obstacleis located. The closer the vehicle symbol is to amarked sector forward/rearward, the closer thedetected obstacle is to your vehicle.
The side sectors change color as the distancebetween the vehicle and an object decreases.
The audible signals will also speed up the closerthe obstacle is to the vehicle. The volume of theaudio system will be automatically lowered.
Audible signals for obstacles in front and to thesides of the vehicle are active when the vehicle ismoving but will cease after the vehicle has beenstationary for approx. 2 seconds. Audible signalsfor obstacles behind the vehicle will remain activeeven when the vehicle is stationary.
If a detected obstacle is within approx. 30 cm(1 ft) from the front or rear of the vehicle, thetone will become constant and the active sen-sor's field closest to the vehicle symbol will befilled in.
At distances within approx. 25 cm (0.8 ft) from anobstacle to the sides of the vehicle, an rapid puls-ing signal will be given and the active sectorfields will change color from ORANGE to RED.
The volume of the Park Assist audible signalscan be adjusted while the signal is being givenusing the >II knob or in the center display's Topview under Settings.

NOTE
Besides in the sector closest to the vehi-cle symbol, audible warnings are only pro-vided for objects located directly in thevehicle's path.
WARNING
The Parking Assist function is supple-mentary driver support intended to facili-tate driving and help make it safer – itcannot handle all situations in all traffic,weather and road conditions.
The parking sensors have dead/blindspots where objects cannot be detected.
Pay particular attention to people andanimals near the vehicle.
Parking Assist is not a substitute for thedriver's attention and judgment. The driveris always responsible for ensuring thevehicle 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.

Park Assist limitations
Park Assist may not be able to detect all condi-tions in all situations and functionality may there-fore be limited in certain cases.
The driver should be aware of the following limi-tations for Park Assist:

WARNING
Be extra cautious whenreversing if this symbol isshown when a trailer, bikecarrier or similar is attachedand electrically connectedto the vehicle.
The symbol indicates thatthe rear parking assist sensors are deacti-vated and will not warn of any obstacles.
CAUTION
Objects such as chains, thin and glossy polesor low obstacles may end up in the "signalshadow" and then go temporarily undetectedby the sensors – the pulsating tone may thenunexpectedly stop instead of becoming aconstant tone as expected.
The sensors cannot detect high objects, suchas protruding ramps.
In such situations, pay extra attention andmaneuver/drive the vehicle very slowly orstop the current parking maneuver –there may be a high risk of damage tothe vehicle or other objects since infor-mation from the sensors is not alwaysreliable in such situations.

CAUTION
In some circumstances, the Park Assist Sys-tem may produce false warnings due to exter-nal sound sources with the same ultrasonicfrequencies as those the system works with.
Examples of such sources are horns, wet tireson asphalt, pneumatic brakes, exhaust noisefrom motorcycles, etc.
NOTE
When a trailer hitch is configured with thevehicle electrical system, the trailer hitch pro-trusion is included when the function meas-ures the distance to objects behind the vehi-cle.
