Seat Warmers
Seat warmers are provided to warm the
seats during cold weather.
During mild weather or under conditions
where the operation of the seat warmer
is not needed, keep the seat warmers
OFF.
WARNING
The seat warmers can cause a SERIOUS
BURN, even at low temperatures and
especially if used for long periods of
time.
Passengers must be able to feel if the
seat is becoming too warm so they can
turn it off, if needed.
People who cannot detect temperature
change or pain to the skin should
use extreme caution, especially the
following types of passengers:
• Infants, children, elderly or disabled
persons, or hospital outpatients.
• People with sensitive skin or who
burn easily.
• Fatigued individuals.
• Intoxicated individuals.
• People taking medication that can
cause drowsiness or sleepiness.
WARNING
NEVER place anything on the seat
that insulates against heat when the
seat warmer is in operation, such as a
blanket or seat cushion. This may cause
the seat warmer to overheat, causing a
burn or damage to the seat.
NOTICE
To prevent damage to the seat warmers
and seats:
• Never use a solvent such as paint
thinner, benzene, alcohol or gasoline
to clean the seats.
• Do not place heavy or sharp objects
on seats equipped with seat
warmers.
• Do not change the seat cover. It may
damage the seat warmer.

Air conditioning
Your Genesis Branded Vehicle air
conditioning system is filled with
R-1234yf refrigerant.
1. Start the vehicle.
2. Press the air conditioning button.
3. Set the mode to the Face Level mode.
4. Set the air intake control to
Recirculation mode temporarily to
allow the cabin to cool quickly. When
the desired temperature in the cabin
is reached, change the air intake
control back to Fresh mode.
5. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
When maximum cooling is desired, set
the temperature control to the lowest
position, then set the fan speed control
to the highest setting.
NOTICE
When using the air conditioning system,
monitor the engine temperature gauge
closely while driving up hills or in heavy
traffic when outside temperatures are
high. Air conditioning system operation
when climbing a steep grade or in
high outside ambient temperatures
can cause engine overheating.
Continue to use the fan, but turn the air
conditioning system off if the engine
temperature gauge indicates engine
overheating. Air conditioning system operation tips
• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
• After sufficient cooling has been
achieved, switch back from
Recirculation mode to Fresh mode.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• If you operate air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield to
fog up, causing loss of visibility. In this
case, set the mode selection to the
position and fan speed control to the
lowest speed.

WARNING
Avoid electrical shocks. Do not place
your fingers or foreign objects (pin, etc.)
into a power outlet or touch the power
outlet with a wet hand.
NOTICE
To prevent damage to the power
outlets:
• Use the power outlet only when the
engine is running and remove the
accessory plug after use. Using the
accessory plug for prolonged periods
of time with the engine off could
cause the battery to discharge.
• Only use 12 volts electric accessories
which are less than 180 watts in
electric capacity.
• Adjust the air-conditioner or heater
to the lowest operating level when
using the power outlet.
• Close the cover when not in use.
• Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static and
malfunctions in other electronic
systems or devices used in your
vehicle.
• Push the plug in as far as it will go. If
good contact is not made, the plug
may overheat and the fuse may open.
• Plug in battery equipped electrical/
electronic devices with reverse
current protection. The current
from the battery may flow into the
vehicle’s electrical/electronic system
and cause system malfunction.

Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the transmission
from P (Park) into R (Reverse) or D (Drive)
unless the brake pedal is depressed.
To shift from P (Park) or N (Neutral) into R
(Reverse) or D (Drive):
1. Depress and hold the brake pedal.
2. Start the engine.
3. Shift gear while depressing the brake
pedal.
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Shift the gear to P (Park), apply the
parking brake, and press the Engine
Start/Stop button to the OFF position.
Take the Key with you when leaving the
vehicle.
WARNING
• When you stay in the vehicle with
the engine running, be careful not
to depress the accelerator pedal for
a long period of time. The engine or
exhaust system may overheat and
start a fire.
• The exhaust gas and the exhaust
system are very hot. Keep away from
the exhaust system components.
• Do not stop or park over flammable
materials, such as dry grass, paper
or leaves. They may ignite and cause
a fire.

Paddle Shifter (Manual Shift
Mode)
OJX1069011OJX1069011
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.
• When driving uphill or downhill,
always shift to D (Drive) for driving
forward or shift to R (Reverse) for
driving rearwards. After selecting
D (Drive) or R (Reverse), 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 occur due to
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.
