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.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds. After both
lights go off, the ESC is enabled.
When operating
When the ESC is in oper-
ation, 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 rou-
tine conditions.
If the Smart Cruise Control was in use when the ESC activates, the
Smart Cruise Control automatically
disengages. The Smart Cruise
Control can be reengaged when
the road conditions allow. See
"Smart 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 accelerator pedal
deeply. This is to maintain the sta-
bility and traction of the vehicle and
does not indicate a problem.
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.

Indicator lights
When the Engine Start/Stop button
is placed to the ON position, the ESC
indicator light illuminates, then goes
off if the ESC system is operating
normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning
light illuminates have your vehicle
checked by an authorized retailer of
Genesis Branded products as soon
as possible.
The ESC OFF indicator light comes
on when the ESC is turned off.Driving with wheel and tire sizes
different than original-equipment
may cause the ESC system to mal-
function. Before replacing tires,
make sure all four tires and
wheels are the same as the origi-
nal 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 trans-
mission:
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 cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) excessive-
ly while these lights are dis-
played.
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 opera-
tion.

The Automatic Emergency Braking
(AEB) system is designed to help
detect and monitor the vehicle ahead
or detect a pedestrian in the roadway
through radar signals and camera
recognition to warn the driver that a
collision is imminent, and if neces-
sary, apply emergency braking.System Setting and Activation
System setting
The driver can activate the AEB by
placing the Engine Start/Stop button
to the ON position and by selecting
'User Settings →Driving Assist →
Autonomous Emergency Braking'.
The AEB deactivates, when the driv-
er cancels the system setting.
The warning light illumi-
nates on the LCD display,
when you cancel the AEB
system. The driver can
monitor the AEB ON/OFF status on
the LCD display. If the warning light
remains ON when the AEB is activat-
ed, have the system checked by an
authorized retailer of Genesis
Branded products.

Take the following precautions
when using the Automatic
Emergency Braking (AEB):
This system is only a supple-
mental system and it is not
intended to, nor does it
replace the need for extreme
care and attention of the driv-
er. The sensing range and
objects detectable by the sen-
sors are limited. Pay attention
to the road conditions at all
times.
NEVER drive too fast in accor- dance with the road condi-
tions or while cornering.
Always drive cautiously to prevent unexpected and sud-
den situations from occur-
ring. AEB does not stop the
vehicle completely and is not
a collision avoidance system.
WARNING
OHI046208L

Driving your vehicle
Remove any dirt, snow, or debris and
clean the radar sensor cover before
operating the AEB system.
The AEB may not properly operate in
an area (e.g. open terrain), where
any substances are not detected
after turning ON the engine.
Do not apply foreign objects such as a bumper sticker or a
bumper guard near the radar
sensor. Doing so may adversely
affect the sensing performance
of the radar.
Always keep the radar sensor and cover clean and free of dirt
and debris.
Use only a soft cloth to wash the vehicle. Do not spray pressur-
ized water directly on the sensor
or sensor cover.
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, the AEB system may
not operate correctly. In this
case, a warning message may
not be displayed. Have the vehi-
cle inspected by an authorized
retailer of Genesis Branded
products.
If the front bumper becomes damaged in the area around the
radar sensor, the AEB system
may not operate properly. Have
the vehicle inspected by an
authorized retailer of Genesis
Branded products.
Use only Genesis/Hyundai Part to repair or replace a damaged
sensor or sensor cover. Do not
apply paint to the sensor cover.
System Malfunction
Check AEB system
When the AEB is not working prop-erly, the AEB warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case,
have the vehicle inspected by an
authorized retailer of Genesis
Branded products.
The AEB warning message may appear along with the illumination
of the ESC (Electronic Stability
Control) warning light.

The severe weather conditions of winter quickly wear out tires and cause
other problems. To minimize winter driving problems, you should take the fol-
lowing suggestions:
Snow or Icy Conditions
You need to keep sufficient distance between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid acceleration, sudden brake applica-
tions, and sharp turns are potentially very hazardous practices. During decel-
eration, use engine braking to the fullest extent. Sudden brake applications on
snowy or icy roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it may be necessary to use snow tires or
to install tire chains on your tires.
Always carry emergency equipment. Some of the items you may want to carry
include tire chains, tow straps or chains, a flashlight, emergency flares, sand,
a shovel, jumper cables, a window scraper, gloves, ground cloth, coveralls, a
blanket, etc.
We recommend you use snow tires when road temperature is below 45°F
(7°C). Refer to the below chart, and mount the recommended snow tire for
your vehicle.
If you mount snow tires on your vehicle, make sure to use the same inflation
pressure as the original tires. However, if you mount 245/45R19 size tire on
the rear, the tire inflation pressure should maintain 35psi. Mount snow tires on
all four wheels to balance your vehicle's handling in all weather conditions.
The traction provided by snow tires on dry road may not be as high as your
vehicle's original equipment tires. Check with the tire dealer for maximum
speed recommendations.
Information
Do not install studded tires without first checking local, state and municipal reg-
ulations for possible restrictions against their use.

If the Engine Doesn't Turn
Over or Turns Over Slowly
Be sure the shift lever is in N(Neutral) or P (Park). The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
Turn on the interior light. If the light dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
Push or pull starting the vehicle
may cause the catalytic converter
to overload which can lead to
damage to the emission control
system.
If the Engine Turns Over
Normally but Doesn't Start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, have
your vehicle checked by an author-
ized retailer of Genesis Branded
products.

Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.
If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver's side cen-
ter pillar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure LCD position
indicator will remain on and the
TPMS Malfunction Indicator may
blink for one minute and then remain
illuminated until you have the low
pressure tire repaired and replaced
on the vehicle.
