Rear Collision Warning

The Rear Collision Warning
69
(RCW) function
can help the driver to avoid being hit by a vehicle
approaching from behind.
This function is activated automatically each time
the engine is started.
Drivers in vehicles behind can be warned about
an imminent collision by the function flashing
intensively with the direction indicators.
If, at a speed below 30 km/h (20 mph), the func-
tion detects that the car is in danger of being hit
from behind, the seatbelt tensioners may tension
the front seatbelts and activate the Whiplash
Protection System safety system.
Immediately before a collision from behind, this
function may also activate the foot brake in order
to reduce the forward acceleration of the car dur-
ing the collision. However, the foot brake is only
activated if the car is stationary. The foot brake
releases immediately if the accelerator pedal is
depressed.

In certain cases the Rear Collision Warning
(RCW) may have difficulty helping the driver in
the event of a collision risk.
This can, for example, be if:
•
the vehicle approaching from behind is
detected too late
•
the vehicle approaching from behind
changes lane at the last moment
•
a trailer, bicycle rack or similar is connected
to the car's electrical system - the function is
then deactivated automatically.
In certain markets, RCW does
not
give a
warning with the direction indicators due to
local traffic regulations - in such cases, this
part of the function is deactivated.
The warning with direction indicators for Rear
Collision Warning is deactivated if the warn-
ing distance for collision warning in the City
Safety function is set at the lowest level
"
Late
".
The seat belt pre-tensioning and braking
functions are, however, still active.
