Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the vehicle is not in the ready
( ) mode or the vehicle is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will
be longer than with power brakes.
When the vehicle is not in the ready
( ) mode, the reserve brake
power is partially depleted each time
the brake pedal is applied. Do not
pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.

Take the following precautions:
Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending down a
long or steep hill, move the
gear shift lever to Manual
Shift Mode and manually
downshift to a lower gear in
order to control your speed
without using the brake pedal
excessively. Applying the
brakes continuously will
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
(Continued)
(Continued)
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
WARNING

Driving your vehicle
Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
i
When you drive on a road hav-
ing poor traction, such as an icy
road, and apply your brakes
continuously, the ABS will be
active continuously and the
ABS warning light ( ) may
illuminate. Pull your car over to
a safe place and turn the vehicle
off.
Restart the vehicle. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.
CAUTION
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as
possible.

VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control(ESC) is on.
Vehicle speed is approximately above 9 mph (15 km/h) on curve
roads.
Vehicle speed is approximately above 12 mph (20 km/h) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active. The VSM does not operate when:
Driving on a banked road such
as gradient or incline.
Driving rearward.
ESC OFF indicator light is on.
EPS (Electric Power Steering) warning light ( ) is on or
blinks.
Driving with wheels and tires with dif-
ferent sizes may cause the ESC sys-
tem to malfunction. Before replacing
tires, make sure all four tires and
wheels are the same size. Never
drive the vehicle with different sized
tires and wheels installed.
NOTICE
If ESC indicator light ( ) or
EPS warning light ( ) stays on
or blinks, your vehicle may have
a malfunction with the VSM sys-
tem.When the warning light illu-
minates, have your vehicle
checked by an authorized
HYUNDAI dealer as soon as pos-
sible.

Prerequisite for activation
The FCA system is on and ready
when FCA is selected on the LCD
display and when the following pre-
requisites are satisfied:
- The ESC (Electronic StabilityControl) is on.
- Driving speed exceeds approxi- mately 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 col-
lide with your vehicle. (The FCA
may not be activated or may sound
a warning alarm in accordance
with the driving situation or vehicle
condition.)
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 Engine Start/
Stop button is in the ON posi-
tion. The driver can deactivate
the FCA by canceling the sys-
tem setting on the LCD dis-
play.
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. The FCA
warning light will illuminate
which is normal.

Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The FCA provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA brake control is automat- ically canceled, when risk factors
disappear.
FCA Sensor
In order for the FCA system to oper-
ate properly, always make sure the
radar sensor cover is clean and free
of dirt, snow, and debris. Dirt, snow,
or foreign substances on the lens
may adversely affect the sensing
performance of the sensor.
The driver should always use
extreme caution while operating
the vehicle, whether or not there
is a warning message or alarm
from the FCA system.
CAUTION
The 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
Never deliberately drive danger-
ously to activate the system.
WARNING
The 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 the
FCA system.

The Lane Keeping Assist (LKA)
System helps detect lane markers on
the road with a camera at the front
windshield, and assists the driver's
steering to help keep the vehicle
between lanes.
When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audible warn-
ing, while applying a slight counter-
steering torque, to try to prevent the
vehicle from moving out of its lane.

The Lane Keeping Assist (LKA)
System is not a substitute for
safe driving practices, but a
convenience function only. It is
the responsibility of the driver
to always be aware of the sur-
rounding and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist (LKA) System:
Do not steer the steering
wheel suddenly when the
steering wheel is being assist-
ed by the system.
LKA system helps to prevent
the driver from moving out of
the lane unintentionally by
assisting the driver's steering.
However, the driver should not
solely rely on the system but
always pay attention on the
steering wheel to stay in the
lane.
(Continued)
WARNING
(Continued)
The operation of the LKA sys-
tem can be canceled or not
work properly according to
road condition and surround-
ings. Always be cautious
when driving.
Do not disassemble the LKA
system camera temporarily to
tint the window or attach any
types of coatings and acces-
sories. If you disassemble the
camera and assemble it again,
take your vehicle to an author-
ized HYUNDAI dealer and
have the system checked for
calibration.
When you replace the wind-
shield glass, LKA system
camera or related parts of the
steering wheel, take your
vehicle to an authorized
HYUNDAI dealer and have the
system checked for calibra-
tion.

LKA System Operation
To activate/deactivate the LKA sys-
tem:
With the Engine Start/Stop button in
the ON position, press the LKA sys-
tem button located on the instrument
panel on the left hand side of the
steering wheel. The indicator in the
cluster display will initially illuminate
white. This indicates the LKA system
is in the READY but NOT ENABLED
state.
(Continued)
After then, if you drive with
your hands on the steering
wheel, the control will be acti-
vated again.
The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
speed when leaving a lane the
vehicle may not be able to be
controlled by the system. The
driver must always follow the
speed limit when using the
system.
If you attach objects to the
steering wheel, the system
may not assist steering or the
hands off alarm may not work
properly.
While other beeps such as the
seat belt warning sound are in
operation and override the
LKA alarming system, LKA
system beeps may not occur.
OAE056050L
(Continued)
The system detects lane
markers and controls the
steering wheel by a camera,
therefore, if the lane markers
are hard to detect, the system
may not work properly.
Please refer to "Limitations of
the system".
Do not remove or damage the
related parts of LKA system.
You may not hear a warning
sound of LKA systembecause
of excessive audio sound.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. The system may malfunc-
tion if the sunlight is reflected.
Always have your hands on
the steering wheel while the
LKA system is activated. If
you continue to drive with
your hands off the steering
wheel after the "Keep hands
on steering wheel" warning
message appears, the system
will turn off automatically.

Information
If the indicator (white) is activated
from the previous ignition cycle, the
system will turn ON without any addi-
tional control. If you press the LKA
system button again, the indicator on
the cluster goes off. The color of indicator will
change depending on the
condition of LKA system.
- White : Sensor does not detect
lane markers or vehicle
speed is under 40 mph (64
km/h).
- Green : Sensor detects lane mark- ers and the system is able
to control vehicle steering.
LKA system activation
To see the LKA system screen onthe LCD display in the cluster,
select SCC/LKA mode ( ) for
cluster type A or ASSIST mode
( ) for cluster type B. For more
information, refer to "LCD Display
Modes" in chapter 3.
When both lane markers are detected and all the conditions to
activate the LKA system are satis-
fied, a green steering wheel indica-
tor will illuminate and the LKA sys-
tem indicator light will change from
white to green. This indicates that
the LKA system is in the
ENABLED state and the steering
wheel will be able to be controlled.

If vehicle speed is over 40 mph (64km/h) and the system detects lane
markers, the color changes from
gray to white.
If the system detects the left lane marker, the left lane marker color
will change from gray to white.
If the system detects the right marker line, the right lane marker
color will change from gray to
white.
Both lane markers must be detect- ed for the system to fully activate. If your vehicle speed exceeds 40
mph (64 km/h) and the LKA sys-
tem button is ON, the system is
enabled. If your vehicle departs
from the projected lane in front of
you, the LKA system operates as
follows:
A visual warning appears on the
cluster LCD display. Either the left
lane marker or the right lane marker
in the cluster LCD display will blink
depending on which direction the
vehicle is veering.
If the steering wheel appears, the
system will control the vehicle's
steering to prevent the vehicle from
crossing the lane marker.Keep hands on steering wheel
If the driver takes their hands off the
steering wheel for several seconds
while the LKA system is activated,
the system will warn the driver.
Information
If the steering wheel is held very light-
ly the message may still appear
because the LKA system may not rec-
ognize that the driver has their hands
on the wheel.
