Rear Collision Warning
The Rear Collision Warning (RCW) function can
help the driver to avoid being hit by a vehicle
approaching from behind.
RCW is activated automatically each time the
engine is started.
The RCW can warn the driver in a vehicle
approaching from behind that a collision is immi-
nent by rapidly flashing the direction indicators.
If, at a vehicle speed below 30 km/h (20 mph),
the RCW function detects that the car is in dan-
ger of being hit from behind, the seatbelt ten-
sioners may tension the front seatbelts and the
Whiplash Protection System safety system is
activated.
Immediately before the collision, RCW may also
activate the foot brake in order to reduce the for-
ward acceleration of the car during the collision.
However, the foot brake is only activated if the
car is stationary. The foot brake releases immedi-
ately if the accelerator pedal is depressed.
Limitations
In certain cases the RCW may have difficulty
helping the driver in the event of a collision risk.
This can be for example:
•
if the vehicle approaching from the rear is
detected too late
•
if the vehicle approaching from the rear
changes lane at the last moment
•
if the vehicle approaching from the rear has a
speed exceeding 80 km/h (50 mph).
NOTE
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.
NOTE
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.

BLIS*
The BLIS

function is designed to give a warn-
ing of vehicles diagonally behind and to the side
of your car so as to give assistance in heavy traf-
fic on roads with several lanes in the same direc-
tion.
BLIS is a driver aid intended to give a warning of:
•
vehicles in the car's blind spot
•
quickly approaching vehicles in the left and
right lanes closest to the car.
