with your ability to use the brake and
accelerator pedals.
• Do not start the vehicle with the
accelerator pedal depressed.

• The vehicle will start by pressing the
Engine Start/Stop button, only when
the smart key is in the vehicle.
• Even if the smart key is in the vehicle,
and when it is far away from the driver,
the engine may not start.
• When the Engine Start/Stop button
is in the ACC or ON position, if any
door is open, the system checks for the
smart key. When the smart key is not
in the vehicle, the “
” indicator
will blink and the warning 'Key not in

WARNING
To reduce the risk of serious injury or
death:
• ALWAYS check the surrounding
areas near your vehicle for people,
especially children, before shifting a
vehicle into D (Drive) or R (Reverse).
• Before leaving the driver's seat,
always make sure the vehicle is
shifted to the P (Park) position, then
apply the parking brake, then press
the Engine Start/Stop button to
the OFF position. Unexpected and
sudden vehicle movement can occur
if these precautions are not followed.
• When using the paddle shifter
(manual shift mode), do not use
engine braking (shifting from a
high gear to lower gear) rapidly on
slippery roads. The vehicle may slip
causing an accident.
Rotary shifter/ Rotary gear shift dial
P (Park)
Always come to a complete stop before
shifting into P (Park).
ORG3060005
To shift the gear to P (Park), press the P
button while depressing the brake pedal.
If you turn the engine off in R (Reverse),
N (Neutral) or D (Drive), the gear will
automatically shift to P (Park).
WARNING
• Shifting into P (Park) while the
vehicle is in motion may cause you to
lose control of the vehicle.
• After the vehicle has stopped, always
make sure the vehicle is in P (Park),
apply the parking brake, and turn the
engine off.
• When parking on an incline, shift
the gear to P (Park) and apply the
parking brake to prevent the vehicle
from rolling downhill.
Automatic gear shift to P (Park)
The gear is shifted to P (Park)
automatically for safety reasons under
the following conditions:
- When the engine is turned off with
the gear in R (Reverse), D (Drive) or N
(Neutral).
-When the driver’s door is opened with
the gear in D (Drive) or R (Reverse)
with the seat belt unfastened and the
vehicle is at a standstill.
-When the driver’s door is opened with
the gear in N (Neutral) and the vehicle
is turned off.
In situations the gear must be in P (Park),
always check if the gear is shifted to P
(Park) by checking the cluster.

Paddle Shifter (Manual Shift
Mode)
ORG3060011
The paddle shifter allows the driver to
shift gear without taking one’s hands off
the steering wheel.
The paddle shifter operates as follow.
• Pull the [+] or [-] paddle shifter once
to shift up or down one gear and the
system changes from automatic shift
mode to manual shift mode.
• To change back to automatic shift
mode from manual shift mode, do one
of the following:
-Pull the [+] paddle shifter for more
than one second.
-Drive the vehicle under 4 mph (7
km/h)
-Gently depress the accelerator
pedal for more than 6 seconds.
-Rotate the shift dial to the D (Drive)
position.
Information
If the [+] and [-] paddle shifters are pulled
at the same time, gear shift may not occur.
Good Driving Practices
• Never shift the gear from P (Park) or
N (Neutral) to any other position with
the accelerator pedal depressed.
• Never shift the gear 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 shift the gear to N (Neutral)
when driving. If the gear is shifted to
N (Neutral) while driving, the vehicle
loses the ability to provide engine
braking. Doing so may increase the
risk of an accident.
Also, shift the gear back to D (Drive)
while the vehicle is moving may
severely damage the transmission.
• Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving 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
performance.
• 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.

During that time, ABS will go through
self-diagnosis and the light will go off if
everything is normal. If the light stays on,
you may have a problem with your ABS.
Contact an authorized retailer of Genesis
Branded products as soon as possible.
WARNING
If the ABS () warning light is on and
stays on, you may have a problem with
the ABS. Your power brakes will work
normally. To reduce the risk of serious
injury or death, contact your authorized
retailer of Genesis Branded products as
soon as possible.
NOTICE
When you drive on a road having poor
traction, such as an icy road, and apply
your brakes continuously, ABS will be
active continuously and the ABS (
)
warning light may illuminate. Pull your
vehicle over to a safe place and turn the
vehicle off.
Restart the vehicle. If the ABS warning
light is off, then your ABS system is
normal.

with your ABS system. Contact an
authorized retailer of Genesis Branded
products as soon as possible.
Information
When you jump start your vehicle because
of a drained battery, the ABS ()
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning. Have the battery
recharged before driving the vehicle.
Electronic Stability Control (ESC)
ORG3060018
Electronic Stability Control 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 management 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.

tires, make sure all four tires and wheels
are the same size. Never drive the
vehicle with different sized wheels and
tires installed.

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
