Good Driving Practices
• Never shift from P (Park) or N
(Neutral) to any other position with
the accelerator pedal depressed.
• Never shift into P (Park) when the
vehicle is in motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
• Do not move the shift lever to N
(Neutral) when driving. If the shift
lever is moved to N (Neutral) while
driving, the vehicle loses the ability
to provide engine braking. Doing
so may increase the risk of an acci-
dent.
• Driving uphill or downhill, always
shift to D (Drive) when driving for-
ward or to R (Reverse) when driv-
ing backwards, and check the gear
position indicated on the cluster
before driving. If you drive in the
opposite direction of the selected
gear, the engine will turn off and a
serious accident might be occurred
due to the degraded brake per-
formance.
• Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can
result in the brakes overheating,
brake wear and possibly even
brake failure.
• Depressing both accelerator and
brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released.• When driving in Manual shift mode
with the paddle shifter, slow down
before shifting to a lower gear.
Otherwise, the lower gear may not
be engaged if the engine rpms are
outside of the allowable range.
• Always apply the parking brake
when leaving the vehicle. Do not
depend on placing the transmis-
sion in P (Park) to keep the vehicle
from moving.
• Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
may cause loss of vehicle control
resulting in an accident.
• Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.

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.
ALL WHEEL DRIVE (AWD) (IF EQUIPPED)

05
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.
