ESC operation
ESC ON condition
When the Engine Start/Stop button is
in the ON position, ESC and the ESC
OFF indicator lights illuminate for
approximately three seconds. After both
lights go off, ESC is enabled.
When operating
When 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 ESC activates, the engine may
not respond to the accelerator as it
does under routine conditions.
• If Cruise Control was in use when
ESC activates, Cruise Control
automatically disengages. Cruise
Control can be reengaged when the
road conditions allow. See “Cruise
Control (CC)” section in chapter 7 (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
accelerator pedal deeply. This is to
maintain the stability and traction of
the vehicle and does not indicate a
problem. ESC OFF condition
To cancel ESC operation:
• State 1
Press the ESC OFF button briefly. The
ESC OFF indicator light and/or message
'Traction Control disabled' will illuminate.
In this state, the traction control function
of ESC (engine management) is disabled,
but the brake control function of ESC
(braking management) still operates.
• State 2
Press and hold the ESC OFF button
continuously for more than 3 seconds.
The ESC OFF indicator light and/or
message 'Traction & Stability Control
disabled' illuminates and a warning
chime sounds. In this state, both the
traction control function of ESC (engine
management) and the brake control
function of ESC (braking management)
are disabled.
If the Engine Start/Stop button is pressed
to the OFF position when ESC is off, ESC
remains off. Upon restarting the vehicle,
ESC will automatically turn on again.

■ ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)
When the Engine Start/Stop button is
pressed to the ON position, the ESC
indicator light illuminates, then goes off
if the ESC system is operating normally.
The ESC indicator light blinks whenever

is active:
Drive slowly and NEVER attempt to
accelerate. NEVER turn ESC off while
the ESC indicator light is blinking or you
may lose control of the vehicle resulting
in an accident.
NOTICE
Driving with wheels and tires with
different 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 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 ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the transmission:
• Do not allow wheel(s) of one axle to
spin excessively while the ESC, ABS,

are displayed. The repairs would not
be covered by the vehicle warranty.
Reduce engine power and do not
spin the wheel(s) excessively while
these lights are displayed.
• When operating the vehicle
on a dynamometer, make sure
ESC is turned off (ESC OFF light
illuminated).
Information
Turning ESC off does not affect ABS or
standard brake system operation.

Vehicle Stability Management
(VSM)
Vehicle Stability Management is a
function of the Electronic Stability
Control (ESC) system. It helps the vehicle
stay stable when accelerating or braking
suddenly on wet, slippery and rough
roads where traction over the four tires
can suddenly become uneven.
WARNING
Take the following precautions when
using Vehicle Stability Management:
• ALWAYS check the speed and the
distance to the vehicle ahead. VSM
is not a substitute for safe driving
practices.
• Never drive too fast for the road
conditions. VSM will not prevent
accidents. Excessive speed in bad
weather, on slippery and uneven
roads can result in severe accidents.
VSM operation
When operating
When you apply your brakes under
conditions which may activate 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.
Information
VSM does not operate when:
• Driving on a banked road such as
gradient or incline.
• Driving in reverse.
• The ESC OFF indicator light is on.
• The EPS (Electric power steering)
warning 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
button again. The ESC OFF indicator light
will go out.
WARNING
If the ESC () indicator light or EPS
() warning light stays illuminated
or blinks, your vehicle may have a
malfunction with the VSM system.
When the warning light illuminates
we recommend that the vehicle be
checked by an authorized HYUNDAI
dealer as soon as possible.
NOTICE
Driving with wheels and tires with
different sizes may cause the VSM
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.
Trailer stability assist (TSA)
Trailer stability assist is operated as a
vehicle stability control system. The
Trailer stability assist system stabilizes
the vehicle and trailer when the trailer
sways or oscillates. There are various
reasons making vehicle sway and
oscillate. In most case it happens at high
speed however, if the trailer is affected
by crosswinds, buffeting, and improper
overloading, it may also be a risk of sway.
Factors of swaying such as:
- High speed
-Strong crosswinds
-Improper overloading
-Sudden controlling of steering wheel
-Uneven road
Trailer stability assist system
continuously analyzes the vehicle
and trailer instability. When the
Trailer stability assist system detects
some sway, the brakes are applied
automatically to stabilize the vehicle
on the front wheel. However, if it is
not enough to stabilize, the brakes are
applied on all wheels automatically and
engine power is properly reduced. When
the vehicle is stable from swaying, trailer
stability assist system does not operate.

Good braking practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Shift the gear to the P (Park)
position, then apply the parking brake,
and press the Engine Start/Stop button
to the 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.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 an authorized HYUNDAI dealer 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 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.

IDLE STOP AND GO (ISG) SYSTEM
Idle Stop and Go helps reduce fuel
consumption by automatically shutting
down the engine, when the vehicle is
at a standstill (i.e. red stop light, stop
sign, and traffic jam) subject to certain
prerequisite conditions being satisfied as
listed below.
The engine is automatically started upon
satisfying the starting conditions.
ISG system is always active, when the
engine is running.
Information
When the engine is automatically started
by ISG system, warning lights (i.e. ABS,
ESC, ESC OFF, EPS, and parking brake
warning light) may illuminate for a few
seconds due to low battery voltage.
However, it does not indicate a
malfunction with ISG system.
