Hyundai Venue: Forward Collision-Avoidance Assist (FCA) System-Sensor Fusion / FCA Warning Message and System Control
FCA produces warning messages and warning alarms in accordance with the collision
risk levels, such as abrupt stopping of the vehicle in front, insufficient braking
distance, or pedestrian detection. Also, it controls the brakes in accordance with
the collision risk levels.
Collision Warning (First warning)

This warning message appears on the LCD display with a warning chime. Additionally,
some vehicle system intervention occurs by the engine management system to help
decelerate the vehicle.
-- Your vehicle speed may decelerate moderately.
-- FCA system limitedly controls the brakes to preemptively mitigate impact in a
collision.
-- If you select ‘Warning only’, FCA system activates and produces only warning
alarms in accordance with the collision risk levels. You should control the brakes
directly because The FCA system will not control the brakes.
Emergency Braking (Second warning)

This warning message appears on the LCD display with a warning chime.
Additionally, some vehicle system intervention occurs by the engine management
system to help decelerate the vehicle.
-- FCA system limitedly controls the brakes to preemptively mitigate impact in
a collision. The brake control is maximized just before a collision.
-- If you select ‘Warning only’, FCA system activates and produces only warning
alarms in accordance with the collision risk levels. You should control the brakes
directly because The FCA system will not control the brakes.
Brake operation
- In an urgent situation, the braking system enters into the ready status
for prompt reaction against the driver’s depressing the brake pedal.
- FCA provides additional braking power for optimum braking performance, when
the driver depresses the brake pedal.
- The braking control is automatically deactivated, when the driver sharply
depresses the accelerator pedal, or when the driver abruptly operates the steering
wheel.
- FCA braking control is automatically canceled, when risk factors disappear.
CAUTION
The driver should always use extreme caution while operating the vehicle,
whether or not there is a warning message or alarm from FCA system.
- After the brake control is activated, the driver must immediately depress
the brake pedal and check the surroundings. The brake activation by the system
lasts for about 2 seconds.
- If any other warning sound such as seat belt warning chime is already
generated, Forward Collision- Avoidance Assist (FCA) system warning may not
sound.
- Playing the vehicle audio system at high volume may prevent occupants
from hearing the system warning sounds.
WARNING
The FCA braking control cannot completely stop the vehicle nor avoid all collisions.
The driver should hold the responsibility to safely drive and control the vehicle.
WARNING
FCA system logic operates within certain parameters, such as the distance
from the vehicle or pedestrian ahead, the speed of the vehicle ahead, and the driver's
vehicle speed. Certain conditions such as inclement weather and road conditions
may affect the operation of FCA system.
WARNING
Never deliberately drive dangerously to activate the system.
System setting
• Setting Forward Safety function
The driver can activate FCA by placing the ignition switch to the ON position
and by selecting:
‘User Settings → Driver Assistance → Forward Safety’
-- If you select “Active Assist”, FCA system activates...

Description
Variable Intake manifold Solenoid (VIS) valve is installed on the intake manifold.
The VIS valve controls the vacuum modulator which activates a valve in the intake
manifold. The ECM opens or closes this valve according to engine condition (Refer
