ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow 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.
NOTICE
To prevent damage to the transmission:
• 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) excessively while
these lights are displayed.
• When operating the vehicle on
a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
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 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 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.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control (ESC) is
on.
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 sensation in the
brake pedal. This is normal and it means
your VSM is active.
NOTICE
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.

The Idle Stop and Go (ISG) system
automatically and temporarily shuts
down the engine when the vehicle
is stopped and idling to improve fuel
efficiency and reduce exhaust gas
emissions. (i.e. red stop light, stop sign,
and traffic jam).
The engine is automatically started upon
satisfying the starting conditions.
The ISG system is always active, when
the engine is running.
Information
When the engine is automatically started
by the ISG system, some warning
lights (i.e. ABS, ESC, ESC OFF, EPS,
and parking brake warning light) may
illuminate for a few seconds due to the
low battery voltage. However, it does
not indicate a malfunction with the ISG
system.
To Activate the ISG System
Prerequisite for activation
The ISG system operates in the following
situations.
• The driver's seatbelt is fastened
• The driver's door and hood are closed
• The brake vacuum pressure is

• Outside temperature is not too low or
too high
• The vehicle is driven over a constant
speed and stops
• The climate control system satisfies
the conditions
• The vehicle is sufficiently warmed up
• The incline is gradual
• The steering wheel is turned less than
180 degrees and then the vehicle
stops
Information
• The ISG system is not
activated, when the
prerequisites to activate
the ISG system are
unsatisfied. In this case,
the ISG OFF button indicator
illuminates, and the auto stop indicator
(
) illuminates in yellow on the

In CUSTOM mode, the driver
can select separate modes
and combine them on the
infotainment system screen.
- E

ngine/Transmission: NORMAL/
SPORT
- S

teering wheel: NORMAL/SPORT
For more infomation, refer to the
separately supplied manual with your
vehicle.
• When CUSTOM mode is selected
by using the DRIVE MODE button,
the CUSTOM mode indicator will
illuminate.
SPORT mode
SPORT mode manages the
driving dynamics by
automatically adjusting the
steering effort, the engine
and transmission control
logic for enhanced driver
performance.
• When SPORT mode is selected by
using the DRIVE MODE button, the
SPORT indicator will illuminate.
• Whenever the engine is restarted,
the Drive Mode will revert back to
NORMAL mode. If SPORT mode is
desired, re-select SPORT mode from
the DRIVE MODE button.
• When SPORT mode is activated:
- The engine rpm will t

end to remain
raised over a certain length of time
even after releasing the accelerator
- Upshifts ar

e delayed when
accelerating
Information
In SPORT mode, the fuel efficiency may
decrease.
SMART mode
00360030002400350037
SMART mode selects the
proper driving mode among
NORMAL and SPORT by
judging the driver’s driving
habits (i.e. Economic or
Aggressive (Sportive)) from
the brake pedal depression
or the steering wheel
operation.
• Toggle the DRIVE MODE button to
select SMART mode. When SMART
mode is selected, the indicator
illuminates on the instrument cluster.
• SMART mode automatically controls
the vehicle driving, such as gear
shifting patterns and engine torque,
in accordance with the driver’s driving
habits.
Information
When you dynamically drive the vehicle
in SMART mode by abruptly decelerating
or sharply turning the driving mode
changes to SPORT mode. However, it may
adversely affect fuel economy.
While Driving

06
6-39
Various driving situations, which you may
encounter in SMART mode
• The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
• You may still sense the engine
braking performance, even when
you release the accelerator pedal in
SMART SPORT mode. It is because
your vehicle remains in lower gear
over a certain period of time for next
acceleration. Thus, it is a normal
driving situation, not indicating any
malfunction.
• The driving mode automatically
changes to SMART SPORT mode only
in harsh driving situations. In most
of the normal driving situations, the
driving mode sets to be in SMART
NORMAL mode. Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indicator
illuminates in those situations.)
•
The driver uses the paddle shifter
(manual shift mode) :
It deactivates SMART mode. The
vehicle drives, as the driver manually
changes gear with the paddle shifter.
• The cruise control is activated :
The cruise control system may
deactivate the SMART mode when
the vehicle is controlled by the set
speed of Smart Cruise Control system.
(SMART mode is not deactivated
just by activating the cruise control
system.)
• The transmission oil temperature is
either extremely low or extremely
high :
The SMART mode can be active in
most of the normal driving situations.
However, an extremely high/ low
transmission oil temperature may
temporarily deactivate the SMART
mode, because the transmission
condition is out of normal operation
condition.

Brake operation
• In an urgent situation, the braking
system enters into the ready status for
prompt reaction against the driver’s
depressing the brake pedal.
• FCA provides additional braking
power for optimum braking
performance, 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.
• FCA brake control is automatically
canceled, when risk factors disappear.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not there is a
warning message or alarm from FCA
system.
• After the brake control is activated,
the driver must immediately depress
the brake pedal and check the
surroundings. The brake activation
by the system lasts for about 2
seconds.
• If any other warning sound such as
seat belt warning chime is already
generated, Forward Collision-
Avoidance Assist system warning
may not sound.
• Playing the vehicle audio system at
high volume may prevent occupants
from hearing the system warning
sounds.
WARNING
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
The FCA system logic operates within
certain parameters, such as the
distance from the vehicle, pedestrian or
cyclist (if equipped) 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
FCA system.
WARNING

Lane Keeping Assist system 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 warning, while
applying a counter-steering torque,
trying to help prevent the vehicle from
moving out of its lane.
WARNING
Lane Keeping Assist 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 surroundings and steer the
vehicle.
WARNING
Take the following precautions when
using Lane Keeping Assist system:
• Do not turn the steering wheel
suddenly when the steering wheel is
being assisted by the system.
• LKA system helps to prevent the
driver from moving out of the lane
(or road) 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.
• The operation of LKA system can
be cancelled or not work properly
according to road condition and
surroundings. Always be cautious
when driving.
• Do not disassemble LKA system
camera temporarily to tint the
window or attach any types of
coatings and accessories. If you
disassemble the camera and
assemble it again, have the vehicle
inspected by an authorized HYUNDAI
dealer and have the system checked
for calibration.

• When you replace the windshield
glass, LKA system camera or related
parts of the steering wheel, have the
vehicle inspected by an authorized
HYUNDAI dealer and have the system
checked for calibration.
• 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
S y s t e m ”.
• Do not remove or damage the related
parts of LKA system.
• You may not hear a warning sound
of LKA system if the audio volume is
high.
• Do not place objects on the
dashboard that reflects light such as
mirrors, white paper, etc. This may
prevent LKA system from functioning
properly. •
Always have your hands on the
steering wheel while 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 stop
controlling the steering wheel.
• The steering wheel is not
continuously controlled so if the
vehicle speed is at a higher rate
when leaving a lane the vehicle may
not 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.
