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 call an author-
ized HYUNDAI dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, butconstant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while 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. Shift
to the P (Park) position, then
apply the parking brake, and
place the POWER button in theOFF position.
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.
WARNING

5-46
Driving your vehicle
- If you select 'Warning Only', FCAsystem activates and produces
only warning alarms in accor-
dance with the collision risk lev-
els. Braking assist will not beapplied in this setting.
- If you select 'Off', FCA system deactivates,
The warning light illumi-
nates on the instrument
cluster, when you cancel
FCA system. The driver
can monitor the FCA ON/OFF status
on the LCD display. Also, the warninglight illuminates when the ESC(Electronic Stability Control) is
turned off.
- If the warning light remains ON when FCA is activated, we recom-
mend that you have the system
checked by an authorized
HYUNDAI dealer. Selecting Warning Timing
The driver can select the initial
warning activation time from theUser Settings in the cluster LCD
display by selecting 'User settings
Driver Assistance Warning
Timing Normal/Late'.
The options for the initial Forward
Collision Warning includes the fol-
lowing:
- Normal: When this option is selected, theinitial Forward Collision Warning is
activated sensitively. If you feel the
warning activates too early, set the
Forward Collision Warning to'Late'. Even though, 'Normal' is selected if
the front vehicle suddenly stops
the initial warning activation time
may not seem fast.
- Late:
When this option is selected, theinitial Forward Collision Warning is
activated later than normal. Thissetting reduces the amount of dis-
tance between the vehicle, pedes-
trian or cyclist ahead before the ini-
tial warning occurs.
Select 'Late' when traffic is light
and when driving speed is slow.
When you accelerate suddenly to
the vehicle ahead, the warning
may seem to activate earlier even if'Late' is selected.
Information
If you change the warning timing, the
warning timing of other systems may
change. Always be aware before
changing the warning timing.

Prerequisite for activation
FCA gets ready to be activated,
when 'Active Assist' or 'Warning
Only' under Forward Safety is select-
ed in the cluster LCD display, and
when the following prerequisites aresatisfied.
- ESC (Electronic Stability Control)is on.
- Vehicle speed is over 8 km/h (5 mph). (FCA is only activated within
a certain speed range.)
- The system detects a pedestrian, cyclist (if equipped) or a vehicle in
front, which may collide with your
vehicle. However, FCA may not be
activated or may only sound a
warning alarm depending on the
driving or vehicle conditions.
The FCA may not operate properly according to the frontal situation,
the direction of pedestrian orcyclist (if equipped) and speed.
FCA warning message and
brake control
FCA produces warning messages,
warning alarms, and emergency
braking based on the level of risk ofa frontal collision, such as when a
vehicle ahead suddenly brakes, orthe system detects that a collision
with a pedestrian or cyclist (ifequipped) is imminent.To avoid driver distractions, do not attempt to set or can-cel FCA while driving the vehi-
cle. Always completely stop
the vehicle at a safe place
before setting or cancelingthe system.
FCA automatically activates
when the POWER button is in
the ON position. The driver
can deactivate FCA by cancel-ing the system setting on the
LCD display.
FCA automatically deactivates upon canceling the ESC
(Electronic Stability Control).When the ESC is canceled,
FCA cannot be activated on
the LCD display. In this situa-
tion, the FCA warning light will
illuminate which is normal.

(Continued)
Be careful not to apply unneces-sary force on the radar sensor or
sensor cover. If the sensor is
forcibly moved out of proper
alignment, FCA system may not
operate correctly. In this case, a
warning message may not be
displayed. We recommend that
you have the vehicle inspected
by an authorized HYUNDAI deal-
er.
If the front bumper becomes damaged in the area around the
front radar sensor, FCA system
may not operate properly. We
recommend that you have the
vehicle inspected by authorized
HYUNDAI dealer.
Use only genuine parts to repair or replace a damaged sensor or
sensor cover. Do not apply paint
to the sensor cover. NEVER install any accessories
or stickers on the front wind-
shield, or tint the front wind-shield.
NEVER place any reflective objects (i.e. white paper, mirror)
over the crash pad. Any light
reflection may prevent the sys-
tem from functioning properly.
Pay extreme caution to keep the camera dry.
NEVER disassemble the camera assembly, or apply any impact
on the camera assembly.
Information
We recommend that you have the sys-
tem checked by an authorized
HYUNDAI dealer when:
 The windshield glass is replaced.
 The front radar sensor or cover gets damaged or replaced.Warning message and warning

Driving your vehicle
When driving in stop-and-go traffic,
and a vehicle in front of you merges
out of the lane, the Forward Collision-
Avoidance Assist system may not
immediately detect the new vehicle
that is now in front of you. In this case,
you must maintain a safe braking dis-
tance, and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe dis-
tance. 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, additional special atten-
tion is required. Forward Collision-
Avoidance Assist system may not
be able to detect the cargo extend-
ing from the vehicle. In these
instances, you must maintain a
safe braking distance from the
rearmost object, and if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain distance.
Detecting pedestrians orcyclists
The sensor may be limited when:
The pedestrian or cyclist is not fully detected by the front view camera
recognition system, for example, if
the pedestrian is leaning over or is
not fully walking upright
The pedestrian or cyclist is moving very quickly or appears abruptly in
the front view camera detectionarea
The pedestrian or cyclist is wear- ing clothing that easily blends into
the background, making it difficult
to be detected by the front view
camera recognition system
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 roadat night)
It is difficult to detect and distin- guish the pedestrian or cyclist from
other objects in the surroundings,
for example, when there is a group
of pedestrians, cyclists or a large
crowd

higher ground clearance.
Forward Collision-Avoidance
Assist system may operate
when an object, which has
similar shape or characteris-
tic to a vehicle, pedestrian or
cyclist, is detected.
FCA system is designed to
detect and monitor the vehicleahead or detect a pedestrian
or cyclist (if equipped) in the
roadway through radar sig-nals and camera recognition. It is not designed to detect
bicycles, motorcycles, or
smaller wheeled objects such
as luggage bags, shopping
carts, or strollers.
