Tachometer
ORS041006ORS041006
ORS042007NORS042007N
The tachometer indicates the
approximate number of engine
revolutions per minute (RPM).
Use the tachometer to select the correct
shift points and to prevent lugging and/
or over-revving the engine.
NOTICE
Do not operate the engine within the
tachometer's RED ZONE. This may
cause severe engine damage.
Engine coolant temperature gauge
ORS042008NORS042008N
ORS042009NORS042009N
This gauge indicates the temperature
of the engine coolant when the Engine
Start/Stop button is in the ON position.
NOTICE
If the gauge pointer moves beyond the
normal range area toward the “H (Hot)”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “If the Engine
Overheats” section in chapter 8.
WARNING
Never remove the engine coolant
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could cause severe burn. Wait until
the engine is cool before adding coolant
to the reservoir.

This message is displayed when the
engine coolant temperature is above
248°F (120°C). This means that the
engine is overheated and may be
damaged.
If your vehicle is overheated, refer to

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.

Convenience Features
Power Outlet
ORS051096
ORS051097
A : Front seat,
B : Rear seat
The power outlet is designed to provide
power for mobile telephones or other
devices designed to operate with vehicle
electrical systems. The devices should
draw less than 180 W with the engine
running.
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 12V electric accessories
which are less than 180 W 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.

Driving Your Vehicle
CAUTION
When you start after stopping on a
steep incline, even if the gear is in
D (Drive), if you do not depress the
accelerator or brake pedal, the vehicle
may roll backwards, which can cause an
accident.
When the battery is discharged
You cannot shift gears, when the battery
is discharged.
In emergencies, do the following to shift
the gear to N (Neutral) on a level ground.
1. Connect the battery cables from
another vehicle or from a another
battery to the jump-starting terminals
inside the engine compartment.
For more details, refer to "Jump
Starting" section in chapter 8.
2. Release the Electronic Parking Brake
with the Engine Start/Stop button in
the ON position.
3. Shift the gear to the N (Neutral)
position. Refer to the “To stay in N
(Neutral) when vehicle is OFF” in this
chapter.
Information
In situations when the gear needs to be
shifted from P (Park) to N (Neutral) when
the Engine Start/Stop button is in the
OFF position, refer to the “To stay in N
(Neutral) when vehicle is OFF” in this
chapter.
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

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
