2020 Hyundai Tucson brake sensor

Safety system of your vehicle
In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to “ride” under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
“underride” collisions.Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.
Information
Vehicles equipped with rollover sensor
The side and curtain air bags may
inflate in a rollover situation, when it
is detected by the rollover sensor.

Limitations of the system
The Forward Collision-Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead on the
roadway using camera recognition to
warn the driver that a collision is
imminent, and if necessary, apply
emergency braking.
In certain situations, the camera may
not be able to detect the vehicle
ahead. In these cases, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
The camera is blocked with a for-
eign object or debris
The camera lens is contaminated
due to a tinted, filmed or coated
windscreen, damaged glass, or
foreign matter is stuck (sticker,
bug, etc.) on the glass
5
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system operates
only to detect a vehicle in
front of the vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect pedestrians in front of
the vehicle.
The FCA system does not
detect vehicles in the oppo-
site lane.
The FCA system does not
detect cross traffic vehicles
that are approaching.
The FCA system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street.)
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.
WARNING

Driving your vehicle
System malfunction
Check FCA
(Forward Collision Avoidance Asst.)
When the FCA is not working prop-
erly, the FCA warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case, we
recommend that you have the vehi-
cle inspected by an authorised
HYUNDAI dealer.
The FCA warning message may
appear along with the illumination
of the ESC (Electronic Stability
Control) warning light.
OIK058091R
The FCA is only a supplemen-
tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and
under certain driving condi-
tions, the FCA system may
activate unintentionally. This
initial warning message
appears on the LCD display
with a warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The FCA system
may not activate and the
warning message will not be
displayed.
Even if there is any problem
with the brake control func-
tion of the FCA system, the
vehicle's basic braking per-
formance will operate normal-
ly. However, the brake control
function for avoiding a colli-
sion will not activate.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.WARNING

Limitations of the system
The Forward Collision-Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a
pedestrian on the roadway through
radar signals and camera recogni-
tion to warn the driver that a collision
is imminent, and if necessary, apply
emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
The radar sensor or camera is
blocked with a foreign object or
debris
The camera lens is contaminated
due to a tinted, filmed or coated
windscreen, damaged glass, or
foreign matter is stuck (sticker,
bug, etc.) on the glass The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system operates
only to detect a vehicle or
pedestrian in front of the vehi-
cle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect vehicles in the oppo-
site lane.
The FCA system does not

that are approaching.
The FCA system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead

In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.
WARNING

5-103
Driving your vehicle
- Driving on a curve
The performance of the FCA sys-
tem may be limited when driving
on a curved road.
On curved roads, the other vehicle
on the same lane is not recognised
and the FCA system's perform-
ance may be degraded. This may
result in unnecessary alarm or
braking or no alarm or braking
when necessary.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
travelling on a curved road.In these cases, the driver must
maintain a safe braking distance,
and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe
distance.
The FCA system may recognise a
vehicle in the next lane when driving
on a curved road.
In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, whilst driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
Check to be sure that the road con-
ditions permit safe operation of the
FCA.
