Electronic Stability Control
(ESC)
The Electronic Stability Control (ESC)
system helps to stabilize the vehicle dur-
ing cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies
braking pressure to any one of the vehi-
cle's brakes and intervenes in the engine
management 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.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF indi-
cator lights illuminate for approximately
three seconds. After both lights go off,
the ESC is enabled.
When operating
When the ESC is in operation,
the ESC indicator light blinks:
When you apply your brakes under conditions which may lock the wheels,
you may hear sounds from the brakes,
or feel a corresponding sensation in
the brake pedal. This is normal and it
means your ESC is active.
When the ESC activates, the engine may not respond to the accelerator as
it does under routine conditions.
If the Cruise Control was in use when the ESC activates, the Cruise Control
automatically disengages. The Cruise
Control can be reengaged when the
road conditions allow. See "Cruise
Control System" later in this chapter. (if
equipped)
When moving out of the mud or driving on a slippery road, the engine RPM
(revolutions per minute) may not
increase even if you press the acceler-
ator pedal deeply. This is to maintain
the stability and traction of the vehicle
and does not indicate a problem.
OAD055010N
Never drive too fast for the road
conditions or too quickly when cor-
nering. The ESC system will not
prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning on
wet surfaces can result in severe
accidents.

(braking management) are disabled.
If the ignition switch is placed to the
LOCK/OFF position when ESC is off, ESC
remains off. Upon restarting the engine,
the ESC will automatically turn on again.
Indicator lights
When the ignition switch is placed to the
ON position, the ESC indicator light illu-
minates, then goes off if the ESC system
is operating normally.
The ESC indicator light blinks whenever
the ESC is operating.
If ESC indicator light stays on, your vehi-
cle may have a malfunction with the ESC
system. When this warning light illumi-
nates have your vehicle checked by an
authorized HYUNDAI dealer as soon as
possible.
The ESC OFF indicator light comes on
when the ESC is turned off.

Driving your vehicle
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 wheels
and tires installed.
ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow or mud by temporarily stopping
operation of the ESC to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface. To prevent damage to the transmis-
sion:
Do not allow wheel(s) of one axle to
spin excessively while the ESC,
ABS, and parking brake warning
lights are displayed. The repairs
would not be covered by the vehicle
warranty. Reduce engine power and
do not spin the wheel(s) excessive-
ly while these lights are displayed.
When operating the vehicle on a dynamometer, make sure the ESC is
turned off (ESC OFF light illuminat-
ed).
Information
Turning the ESC off does not affect ABS
or standard brake system operation.

Vehicle Stability Management
(VSM)
The Vehicle Stability Management (VSM)
is a function of the Electronic Stability
Control (ESC) system. It helps ensure
the vehicle stays stable when accelerat-
ing or braking suddenly on wet, slippery
and rough roads where traction over the
four tires can suddenly become
uneven.
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 con-
ditions which may activate the ESC, you
may hear sounds from the brakes, or feel
a corresponding sensation in the brake
pedal. This is normal and it means your
VSM is active.
The VSM does not operate when:
Driving on a banked road such asgradient or incline.
Driving rearward.
ESC OFF indicator light is on.
EPS (Electric Power Steering) warn- ing light ( ) is on or blinks.
VSM OFF condition
To cancel VSM operation, press the ESC
OFF button. ESC OFF indicator light ( )
will illuminate.
To turn on VSM, press the ESC OFF but-
ton again. The ESC OFF indicator light
will go out.
Driving with wheels and tires with differ-
ent sizes may cause the ESC system 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
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and the
distance to the vehicle ahead. The
VSM is not a substitute for safe
driving practices.
Never drive too fast for the road
conditions. The VSM system will
not prevent accidents. Excessive
speed in bad weather, slippery
and uneven roads can result in
severe accidents.
WARNING If ESC indicator light ( ) or EPS
warning light ( )
stays on or blinks, your vehicle may
have a malfunction with the VSM
system. When the warning light illu-
minates, have your vehicle checked
by an authorized HYUNDAI dealer
as soon as possible.

Driving your vehicle
Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC) helps
prevent the vehicle from rolling back-
wards when starting a vehicle from a
stop on a hill. The system operates the
brakes automatically for approximately 2
seconds and releases the brake after 2
seconds or when the accelerator pedal is
depressed.
The HAC does not operate when theshift lever is in P (Park) or N
(Neutral)
The HAC activates even though the ESC (Electronic Stability Control) is
off but does not activate when the
ESC has malfunctioned.
Good Braking Practices
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is driv-
en 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 light-
ly until the braking action returns to nor-
mal, taking care to keep the vehicle
under control at all times. If the braking
action does not return to normal, stop as
soon as it is safe to do so and call an
authorized HYUNDAI dealer for assis-
tance.
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 tire goes flat while you are driving,
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 forward.
NOTICE
Always be ready to depress the
accelerator pedal when starting off
on a incline. The HAC activates only
for approximately 2 seconds.
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the
brake pedal. Move the shift lever
into the 1
stgear (for manual trans-
mission vehicle) or P (Park, for
automatic transmission vehicle)
position, then apply the parking
brake, and place the ignition switch
in the LOCK/OFF position.
Vehicles parked with the parking
brake not applied or not fully
engaged may roll inadvertently and
may cause injury to the driver and
others. ALWAYS apply the parking
brake before exiting the vehicle.

AEB Warning Message and
System Control
The AEB produces warning messages
and warning alarms in accordance with
the collision risk levels, such as abrupt
stopping of the vehicle in front, insuffi-
cient braking distance, or pedestrian
detection. Also, it controls the brakes in
accordance with the collision risk levels.
Forward Warning (1stwarning)
This initial warning message appears on
the LCD display with a warning chime.
The driver can select the initial warning
activation time in the User Settings in the
LCD display. The options for the initial
Forward Collision Warning include
EARLY, NORMAL, or LATE initial warn-
ing time.
Collision Warning (2ndwarning)
This warning message appears on theLCD display with a warning chime.
The AEB system limitedly controls the brakes to preemptively mitigate impact
in a collision.

Emergency Braking(3rdwarning)
This warning message appears on the
LCD display with a warning alarm.
The AEB system limitedly controls the brakes to preemptively mitigate impact
in a collision.
- The brake control is maximized justbefore a collision.
Brake operation
In an urgent situation, the braking sys- tem enters into the ready status for
prompt reaction against the driver’s
depressing the brake pedal.
The AEB provides additional braking power for optimum braking perform-
ance, 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.
The AEB braking control is automati- cally canceled, when risk factors dis-
appear.
OAD055041N
■ Supervision cluster (Type B)
The driver should always use
extreme caution while operating
the vehicle, whether or not there is
a warning message or alarm from
the AEB system.
CAUTION
The AEB 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 AEB system.
WARNING
The AEB braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility to
safely drive and control the vehicle.

System Malfunction
When the AEB is not working properly,the AEB warning light ( ) will illumi-
nate and the warning message will
appear for a few seconds. After the
message disappears, the master warn-
ing light ( ) will illuminate. In this
case, have the vehicle inspected by an
authorized HYUNDAI dealer.
The AEB warning message may appear along with the illumination of
the ESC warning light.

OAD055018/OLF056473N
The AEB is only a supplemental
system for the driver’s conven-
ience. The driver should hold the
responsibility to control the vehi-
cle operation. Do not solely
depend on the AEB 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 conditions, the
AEB system may activate prema-
turely. This initial warning mes-
sage 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 pedestrian
ahead. The AEB system may not
activate and the warning mes-
sage will not be displayed.
(Continued)
WARNING (Continued)
If there is a malfunction with the
AEB system, the automatic emer-
gency braking is not applied even
though the braking system is
operating normally.
The AEB system operates only to
detect vehicles or pedestrians in
front of the vehicle.
The AEB system does not oper-
ate when the vehicle is in reverse.
The AEB system is not designed
to detect other objects on the
road such as animals.
The AEB system does not detect
cross traffic vehicles that are
approaching.
The AEB 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 driving speed
in order to maintain a safe dis-
tance.(Continued)
