Hill-Start Assist Control (HAC)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systems
are automatically released, when the
accelerator pedal is depressed.
Information
• The HAC does not operate when theshift lever is in P (Park) or N (Neutral).
• The HAC activates even when the ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not operate nor-
mally.
Emergency Stop Signal (ESS)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, whilst sharply and
severely braking.
The system is activated when:
The vehicle suddenly stops. (Thedeceleration power exceeds 7 m/s
2,
and the driving speed exceeds 34
mph (55 km/h).)
The ABS is activated.
The hazard warning flasher automat-
ically turns ON after blinking the stop
lights:
When the driving speed is under 25 mph (40 km/h),
When the ABS is deactivated, and
When the sudden braking situation is over. The hazard warning flasher turns
OFF:
When the vehicle drives at a low
speed for a certain period of time.
The driver can manually turn OFF
the hazard warning flasher by
pressing the button.
Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flashers are already on.

i
The HAC is activated only for
about 2 seconds, so always
depress the accelerator pedal
to begin driving upwards after a
stop.

Good braking practices
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side.To dry the brakes, apply the brakes
lightly until the braking action returns
to normal. If the braking action does
not return to normal, stop as soon as
it is safe to do so and we recommend
that you call a HYUNDAI authorised
repairer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tyre goes flat whilst you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead whilst you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the ignition
switch in the LOCK/OFF posi-
tion.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.

Prerequisite for activation
The FCA gets ready to be activated,
when the FCA is selected on the
LCD display, and when the following
prerequisites are satisfied.
- The ESC (Electronic StabilityControl) is on.
- Vehicle speed is over 6 mph (10 km/h). (The FCA is only activated
within a certain speed range.)
- The system detects a pedestrian or a vehicle in front, which may collide
with your vehicle. (The FCA may
not be activated or may sound a
warning alarm in accordance with
the driving situation or vehicle con-
dition.)
FCA warning message and
system control
The FCA produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels.Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate
/deactivate the FCA system.
The FCA automatically acti-
vates when the ignition switch
is in the ON position. The driv-
er can deactivate the FCA by
canceling the system setting
on the LCD display.
If you cancel the ESC
(Electronic Stability Control)
when the FCA system is
turned on the FCA automati-
cally deactivates and the FCA
warning light illuminates.
When the ESC is cancelled
the FCA cannot be activated
on the LCD display.

Limitations of the system
The Forward Collision-avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a pedes-
trian in the roadway through radar sig-
nals and camera recognition 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 isblocked with a foreign object or
debris
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro- magnetic waves There is severe irregular reflection
from the radar sensor
The radar/camera sensor recogni- tion is limited
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
The driver's field of view is not well illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
The vehicle in front does not have their rear lights properly turned ON
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel
Light coming from a street light or an oncoming vehicle is reflected on
a wet road surface such as a pud-
dle in the road
The field of view in front is obstructed by sun glare
The FCA system operates only
to detect vehicles or pedestri-
ans 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 vehicles in the opposite
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 vehicle (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

5-60
Driving your vehicle
- Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The FCA system may not be able to
detect the cargo extending from the
vehicle. In these instances, you must
maintain a safe braking distance
from the rearmost object, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
Detecting pedestrians (if equipped)
The sensor may be limited when:
The pedestrian is not fully detected
by the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
It is difficult to detect and distin- guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
There is an item similar to a per- son’s body structure
The pedestrian is small
The pedestrian has impaired mobility
The sensor recognition is limited The radar sensor or camera is
blocked with a foreign object or
debris
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
The outside lighting is too bright (e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night)
When light coming from a street light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road
The field of view in front is obstructed by sun glare
The windscreen glass is fogged up; a clear view of the road is
obstructed
The adverse road conditions cause excessive vehicle vibrations whilst
driving
