NOTE
Driver support 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 beforedriver support 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 the func-tion will go into standby mode. This means thatthe brakes 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 the function 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 the function is keeping the vehiclestationary using the brakes and:
the driver opens the door or unbuckleshis/her seat belt
the function has kept the vehicle at a stand-still for more than approx. 5 minutes
the brakes overheat
the driver switches off the engine manually.

Passing assistance
Passing assistance can assist the driver whenpassing other vehicles. The function can beused with Pilot Assist or Adaptive Cruise Con-
trol* (ACC40).
How passing assistance works
When Pilot Assist or ACC is following anothervehicle and you indicate that you intend to pass
that vehicle by using the turn signal41, the systemwill begin accelerating toward the vehicle aheadbefore your vehicle has moved into the passinglane.
The function will then delay a speed reduction toavoid early braking as your vehicle approaches aslower-moving vehicle.
The function remains active until your vehicle haspassed 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.

Using passing assistance
Several conditions must be met for passingassistance to be possible.
In order to activate passing assistance:
your vehicle must be following a vehicleahead (target vehicle)
your vehicle's current speed must beat least 70 km/h (43 mph)
the set speed must be high enough tosafely pass another vehicle.
To start passing assistance:
–Turn on the left turn signal.
>Passing assistance will start.
WARNING
The driver should be aware that if conditionssuddenly change when using Passing 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
Situations of this type can be avoided by tempo-rarily putting Adaptive Cruise Control or PilotAssist in standby mode.

Rear Collision Warning51
The Rear Collision Warning52 (RCW) functioncan help the driver avoid rear-end collisions fromvehicles approaching from behind.
The function is automatically activated each timethe engine is started.
The function can alert drivers of following vehi-cles of the risk of a collision by rapidly flashingthe turn signals.
If, at a speed below 30 km/h (20 mph), the func-tion detects that the vehicle is in danger of beinghit from behind, the seatbelt tensioners may ten-sion the front seat belts and activate theWhiplash Protection System safety system.
Immediately before a collision from behind, thefunction may also activate the brakes in order toreduce the forward acceleration of the vehicleduring the collision. However, the brakes will onlybe applied if your vehicle is stationary. The brakeswill be immediately released if the acceleratorpedal is depressed.

Rear Collision Warning53 limitations
In some situations, it may be difficult for RearCollision Warning (RCW) to warn the driver of acollision risk.
This may be the case if:
the vehicle approaching from the rear isdetected at a late stage
the vehicle approaching from the rearchanges lanes at a late stage
a trailer, bicycle holder or similar is con-nected to the vehicle's electrical system - thefunction will then be automatically deacti-vated.
NOTE
In certain markets RCW does not warn withthe direction indicators due to local trafficregulations – in such cases, that part of thefunction is deactivated.
NOTE
The warning with direction indicators for RearCollision 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.

Lane Keeping Aid
Lane Keeping Aid (LKA80) is designed toactively steer the vehicle on freeways, highwaysand other major roads to help the driver reducethe risk of the vehicle unintentionally veering outof the lane.
Lake Keeping Assistance steers the vehicle backinto the lane and/or alerts the driver using vibra-tions in the steering wheel.
Lane Keeping Aid is active at speeds between65–200 km/h (40–125 mph) on roads withclearly visible traffic lane marker lines.
On narrow roads, the function may be unavailableand go into standby mode. The function willbecome available again when the road becomessufficiently wide.
A camera monitors the road/traffic lane's marker lines.
Lane Keeping Aid steers the vehicle back into its lane.
Lane Keeping Aid alerts the driver using vibrations in thesteering wheel.
Depending on the settings used, Lane KeepingAid functions in different ways:
Assist enabled: When the vehicleapproaches a lane marker line, the functionwill actively steer the vehicle back into thelane using light pressure on the steeringwheel.
Warning enabled: If the vehicle is about tomove over a lane marker line, the driver willbe alerted by vibrations in the steering wheel.
NOTE
When the direction indicators/turn signals areactivated, the Lane Keeping Aid does not pro-vide any warning or intervene with steering.

Run-Off Mitigation with steeringassistance
Steering assistance has several sub-functions.Run-Off Mitigation with steering assistance canhelp the driver and reduce the risk of the vehicleinadvertently running off the road by activelysteering the vehicle back onto the road.
The function is active at speeds between65-140 km/h (40-87 mph) on roads with clearlyvisible traffic lane markings/lines.
The system uses a camera to monitor the edgesof the road and the painted side marker lines. Ifthe vehicle is about to cross the edge of the road,the function will attempt to steer the vehicle backonto the road. If this is not sufficient to keep thevehicle on the road, the brakes will also beapplied.
However, the function will not provide eithersteering assistance or braking if the turn signal isused. The function will also not be activated if itdetects that the driver is actively operating thevehicle.
After the system has automatically intervened,this text message will appear in the instrumentpanel:
