It is possible that collision warnings are
not given, are given too late or seem
unjustied.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
If you select "Far" in the touch screen,
then the system warns sooner. This
increases the safety but increases also the
amount of alerts, if the legal safety distance is
not kept.
To reduce the alert occurrence, you can
change the setting to either of the other two.
Intelligent emergency
braking assistance (iEBA)
This function increases vehicle deceleration
if the driver does not brake enough to avoid a
collision.
This assistance is only provided if the driver
presses the brake pedal.
Active Safety Brake
This function, also called "automatic emergency
braking", intervenes after the acoustic alert if the
driver does not operate the brake pedal quickly
enough.
The system aims at reducing the speed of
impact or avoiding a collision if the driver fails to
react.
The speed will be reduced by a
maximum of 12 mph (20 km/h) (versions
with camera only) or by a maximum of 31
mph (50 km/h) (versions with camera and
radar).
Operation
The system operates in the following speed
ranges:
– Between 3 mph and 50 mph (5 km/h and
80 km/h) when a stationary vehicle is detected.
– Between 3 mph and 50 mph (5 km/h and
80 km/h) when a pedestrian is detected.
– Between 3 mph and 50 mph (5 km/h and
80 km/h) when a cyclist is detected (versions
with camera and radar only).
– Between 3 mph and 50 mph (5 km/h and
80 km/h) (versions with camera only) or 87 mph
(140 km/h) (versions with cameras and radar)
when a moving vehicle is detected.
This warning lamp ashes (for
approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
During the ashing time, the function is not
available.
With an automatic gearbox or drive selector, in
the event of automatic emergency braking, keep
the brake pedal depressed, also after a complete
stop is reached, to prevent the vehicle from
rolling away.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can override the automatic
emergency braking at any time by
strongly turning the steering wheel (evasive
manoeuver) and/or by rmly pressing the
accelerator pedal.
