Steering assistance with braking
Intervention with steering assistance and braking
Braking intervention assists in situations where steering assistance alone is not suffi-cient. Braking force is automatically adaptedaccording to the situation at the moment thevehicle begins to run off the road. The function is active at speeds between 65-140 km/h (40-87 mph) on roads withclearly visible traffic lane markings/lines. The system uses a camera to monitor the edges of the road and the painted side markerlines. If the vehicle is about to cross the edgeof the road, the function will attempt to steerthe vehicle back onto the road. If this is notsufficient to keep the vehicle on the road, thebrakes will also be applied. However, the function will not provide either
steering assistance or braking if the turn signal is used. The function will also not be activated if it detects that the driver is actively operatingthe vehicle.

Rear Collision Warning *85
The Rear Collision Warning 86
(RCW) function
can help the driver avoid rear-end collisions from vehicles approaching from behind.
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 function detects that the vehicle is in dangerof being hit from behind, the seat belt tension-ers may tension the front seat belts. TheWhiplash Protection System will also be acti-vated in a collision. Immediately before a collision from behind, the function may also activate the brakes inorder to reduce the forward acceleration of thevehicle during the collision. However, thebrakes will only be applied if your vehicle isstationary. The brakes will be immediatelyreleased if the accelerator pedal is depressed. The function is automatically activated each time the engine is started.

The BLIS 88
function is designed to help pro-
vide assistance in heavy traffic with several lanes moving in the same direction by helpingthe driver to detect the presence of vehiclesin the "blind spot" area behind and to the sideof the vehicle.
Location of BLIS indicator light
BLIS is a driver support system designed to alert the driver of:
vehicles in your "blind spot"
vehicles approaching rapidly in adjacentlanes.
BLIS overview
Blind spot zone
Rapidly approaching vehicle zone
The system is designed to react to:
vehicles passing your vehicle
vehicles that are rapidly approaching your vehicle from behind.
When BLIS detects a vehicle in zone 1 or arapidly approaching vehicle in zone 2, an indi-cator light will illuminate in the relevant rear-view mirror and glow steadily. If the driverthen uses the turn signal on the side in whichthe warning has been given, the indicator lightwill become brighter and begin flashing. BLIS is active when your vehicle is traveling at a speed over 10 km/h (6 mph).

Driver Alert Control
The Driver Alert Control (DAC) function is designed to help alert the driver to erraticbehavior, e.g. if the driver is distracted orshowing signs of fatigue.
The objective of the function is to detect slowly deteriorating driving behavior and isprimarily intended to be used on major roads.The function is not intended for use in city traf-fic. DAC is activated when the vehicle's speed exceeds 65 km/h (40 mph) and remainsactive as long as speeds are above 60 km/h(37 mph).
Driver Alert Control detects the vehicle's position in the traffic lane.
A camera monitors the traffic lane's marker lines and compares the direction of the road with the driver's movements of the steeringwheel.
The vehicle is moving erratically in the lane.
If driving behavior becomes considerably erratic, thedriver will be alerted by thissymbol in the instrumentpanel, an audible signal and the message
Time for a
break.
If the vehicle is equipped with Sensus Navigation * and the Rest Stop Guidancefunction is activated, suggestions will also be provided for suitable places to take a break. The warning will be repeated after a short time if driving behavior does not improve.
WARNING
Driver Alert Control must not be used to extend a period of driving. The drivershould plan in breaks at regular intervalsand make sure they are well rested.
WARNING
An alarm from Driver Alert Control should be taken very seriously since a sleepy driveris often not aware of their own condition. If the alarm sounds or you feel fatigued:
Stop the vehicle safely as soon as pos- sible and rest.
Studies have shown that it is just as dan- gerous to drive while tired as it is to driveunder the influence of alcohol or otherstimulants.
