System Limitations
Automated Emergency Braking may
be impaired or may not function in the
following situations:
• If there is poor visibility, e.g. due to
insufficient illumination of the road,
if there are highly variable shade
conditions or in rain, snow or fog.
• If there is glare, e.g. from oncoming
traffic, direct sunlight or reflections
from other vehicles.
• If the windshield in the area of the
camera is dirty, or if the camera is
fogged up, damaged or covered.
• During air suspension transitions.
System Operation
The FCW provides audible and visual
warnings when a potential collision is
detected. Brake jerk and limited braking
may also be applied depending on the
specific scenario.
FCW monitors the information from the
forward looking radar sensor and camera
(2 more corner radar sensors are present
in the front part of the car when ICA is
equipped) to calculate the probability
of a forward collision; the Electronic
Brake Controller (EBC) will execute
the brake request. When the system
determines that a forward collision is
probable, the driver will be provided
with audible and visual warnings and
may provide a warning brake jerk. If
the driver does not take action based
upon these progressive warnings, then
the system will provide a limited level
of active braking to help slow down
the vehicle and mitigate the potential
forward collision. If the driver reacts to
the warnings by braking and the system
determines that the driver intends to
avoid the collision by braking but has
not applied sufficient brake force, the
system will compensate and provide
additional brake force as required.
When the system determines a collision
with the vehicle in front of you is no
longer probable, the warning messages
will be deactivated.
NOTE:
• Bad weather conditions, like strong
rain, snow, etc., can lead to reduced
system performance. Under these
conditions relevant objects will not
be detected or detected late by the
system.
• FCW is designed to react in specific
situations in typical traffic scenarios
with objects in the same lane driving
in the same direction, but under
certain conditions it can also react on
stationary objects in the same lane.
The system is designed to react to
oncoming traffic or crossing traffic
(only with ICA ( )).
Driving and Driver Assistance Systems
• The FCW alerts may be triggered on
objects other than vehicles such as
guard rails or sign posts based on the
course prediction. This can occur but
it is not part of normal FCW activation
and functionality.
• It is unsafe to test the FCW system.
To prevent such misuse of the system,
after four Active Braking events within
an ignition cycle, the Active Braking
portion of FCW will be deactivated
until the next ignition cycle. The limit
of four events applies to the brake jerk
too.
• The FCW system is intended for on-
road use only. If the vehicle is taken
off-road, the FCW system should be
deactivated to prevent unnecessary
warnings.
• FCW will automatically deactivated
when ESC OFF button is pressed (LED
light up).
WARNING!
• Forward Collision Warning (FCW) is
not intended to avoid a collision on its
own, nor can FCW detect every type
of potential collision. The driver has
the responsibility to avoid a collision
by controlling the vehicle via braking
and steering. Failure to follow this
