Rear Collision Warning (RCW)
The
Rear Collision Warning
(RCW) function
can help the driver avoid rear-end collisions.
RCW is activated automatically each time the
engine is started.
RCW can warn the driver of a vehicle approach-
ing yours from behind by rapidly flashing your
turn signals.
RCW is only activated when a vehicle is rapidly
approaching your vehicle from behind.
At speeds below 20 mph (30 km/h), if RCW
determines that your vehicle is at risk of a rear-
end collision, the front seat belt pretensioners
and the Whiplash Protection System are acti-
vated.
Just prior to the collision, the brakes are also
applied to help reduce your vehicle's forward
movement if and when the collision occurs. How-
ever, this can only happen if your vehicle is sta-
tionary.
The brakes will be released immediately if the
accelerator pedal is pressed.
NOTE
•
Due to local traffic regulations in certain
markets, Rear Collision Warning (RCW)
will
not
activate the rear turn signals.
That part of the function will be deacti-
vated.
•
The use of the rear turn signals will also
be deactivated if the City Safety warning
level is set at
Later
. See also the section
"Setting a warning level (distance)" in the
article "City Safety settings."
•
If RCW detects a vehicle approaching
from behind, the seat belt pretensioners
and Whiplash Protection System will be
activated.
Limitations
In some circumstances, it may be difficult for
RCW to help the driver if there is a risk of a colli-
sion, such as:
•
If the vehicle approaching from the rear is
detected at a late stage
•
If the vehicle approaching from the rear
changes lanes at a late stage
•
If the vehicle approaching from the rear is
moving at a speed above approx. 50 mph
(80 km/h)
