Electronic Stability Control
(ESC)
The Electronic Stability Control sys-
tem 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 vehicle's brakes and inter-
venes in the engine management
system to assist the driver with keep-
ing 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.
• 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.
OHI058037
Never drive too fast for the road
conditions 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 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.

WARNING

Using All Wheel Drive (AWD)
The All Wheel Drive system delivers
engine power to front and rear
wheels for maximum traction. AWD is
useful when extra traction is
required, such as when driving on,
muddy, wet, or snow-covered roads.
If the system determines there is a
need for four wheel drive, the
engine's driving power is distributed
to all four wheels automatically.

If the AWD warning light ( )
stays on the instrument cluster,
your vehicle may have a mal-
function with the AWD system.
When the AWD warning light
( ) illuminates have your
vehicle checked by an author-
ized retailer of Genesis Branded
products as soon as possible.
WARNING
To reduce the risk of SERIOUS
INJURY or DEATH:
• Do not drive in conditions that
exceed the vehicles intended
design such as challenging
off-road conditions.
• Avoid high speeds when cor-
nering or turning.
• Do not make quick steering
wheel movements, such as
sharp lane changes or fast,
sharp turns.
• The risk of a rollover is great-
ly increased if you lose con-
trol of your vehicle at highway
speeds.
• Loss of control often occurs if
two or more wheels drop off
the roadway and the driver
over steers to reenter the
roadway.
• In the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.
• Always drive safely and use
caution when driving an AWD
vehicle.
WARNING

Information
• Do not drive in water if the level is
higher than the bottom of the vehi-
cle.
• Check your brake condition once
you are out of mud or water.
Depress the brake pedal several
times as you move slowly until you
feel normal braking return.
• Shorten your scheduled mainte-
nance interval if you drive in off-
road conditions such as sand, mud
or water (see "Maintenance Under
Severe Usage Conditions" in chap-
ter 7).
• Make sure that an AWD vehicle is
towed by flatbed tow truck.
For safe AWD operation
Before driving
• Make sure all passengers are
wearing seat belts.
• Sit upright and adjust the steering
wheel to a position comfortable for
you to drive.
Driving on snow-covered or icy
roads
• Start off slowly by applying the
accelerator pedal gently.
• Use of snow tires is recommended.
For more information on Snow
Tires refer to "Winter Driving" in
this chapter.
• Keep sufficient distance between
your vehicle and the vehicle in front
of you.
• When approaching a stop sign or
stop light, release the accelerator
pedal to provide engine braking
during deceleration.
• Avoid speeding, rapid acceleration,
sudden brake applications, and
sharp turns to prevent skids.

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.
Snow tires
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 you Have a Flat Tire While
Driving
If a tire goes flat while you are driv-
ing:
• Take your foot off the accelerator
pedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause loss of vehicle
control resulting in an accident.
When the vehicle has slowed to
such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes.
• When the vehicle is stopped, press
the hazard warning flasher button,
shift the gear to P (Park), apply the
parking brake, and press the
Engine Start/Stop button to the
OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
• When changing a flat tire, follow
the instructions provided later in
this chapter.If the Engine Doesn't Turn
Over or Turns Over Slowly
• Be sure to shift the gear to N
(Neutral) or P (Park). The engine
starts only when the gear 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.

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.
