ACTIVE EMERGENCY BRAKING (2/8)
Operation
Detection of vehicles
When driving, in the event of a risk of
collision with the vehicle in front the
system will:
– warn of the risk of collision: when
the vehicle speed is between 4 mph
(7 km/h) and 106 mph (170 km/h),
the message “Brake” is displayed
in red on the instrument panel 3 ac-
companied by an audible warning.
If the driver presses the brake pedal
and the system still detects a risk
of collision, the brake force is in-
creased;
– braking may be triggered: when
the vehicle is moving slower than ap-
proximately 53 mph (85 km/h), if the
driver does not respond to the warn-
ing and a collision becomes immi-
nent.
In the event of emergency manoeu-
vre, you can stop braking at any
moment by:
– tapping the accelerator pedal;
or
– turning the steering wheel as a
collision avoidance manoeuvre.
Special features of warnings
Depending on the speed, the warning
and braking may be activated simulta-
neously.
Special features of stationary
vehicles
Stationary vehicles are detected when
your vehicle is being driven at a speed
between approximately 4 mph (7 km/h)
and 50 mph (80 km/h). The system is
not active and does not emit a warning
for stationary vehicles when you exceed
approximately 50 mph (80 km/h).
If the vehicle stopped as a result of
active emergency braking, the driver
must keep the vehicle stationary by ap-
plying the brake pedal.
Note: if the driver uses the vehicle con-
trols (steering wheel, pedals, etc.) the
system may delay certain operations or
not activate.
