VEHICLE MODIFICATIONS
• This vehicle should not be modified. Modification of your vehicle could affect its
performance, safety or durability and may even violate governmental safety and
emissions regulations.
• In addition, damage or performance problems resulting from any modification may
not be covered under warranty.
• If you use unauthorized electronic devices, it may cause the vehicle to operate
abnormally, wire damage, battery discharge and fire. For your safety, do not use
unauthorized electronic devices.
NOTICE
All warning sounds (e.g. welcome/good-bye sound, virtual engine sound) are
generated from the interior amplifiers. If necessary, we recommend you to purchase
Genesis Part to replace an interior amplifier. Any unauthorized product may cause a
malfunction of the interior amplifiers.
VEHICLE BREAK-IN PROCESS
• Do not race the engine.
• While driving, keep your engine speed (rpm, or revolutions per minute) between
2,000 rpm and 4,000 rpm.
• Do not maintain a single speed for long periods of time, either fast or slow. Varying
engine speed is needed to properly break-in the engine.
• Avoid hard stops, except in emergencies, to allow the brakes to seat properly.

Recommended SAE Viscosity Number
CAUTION
Always be sure to clean the area around any filler cap, drain plug, or dipstick before
checking or draining any lubricant. This is especially important in dusty or sandy
areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick
areas will prevent dirt and grit from entering the engine and other mechanisms that
could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher viscosity
engine oils are required for satisfactory lubrication in hot weather. Using oils of any
viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operated
in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.

*1 : For better fuel economy, it is recommended to use the engine oil of a viscosity grade
SAE 0W-30. However, if the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.
An engine oil displaying this American Petroleum Institute(API) Certification Mark conforms to the International Lubricant
Specification Advisory Committee (ILSAC). It is recommended to
only use engine oils that uphold this API Certification Mark.

Engine oil pressure warning
light
This warning light illuminates:
When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
engine oil level (For more details,
refer to “Engine Oil” section in
chapter 2). If the level is low, add oil
as required.
If the warning light remains on after
adding oil or if oil is not available, have
the vehicle inspected by an authorized
retailer of Genesis Branded products
as soon as possible.
NOTICE
• If the engine is not stopped
immediately after the Engine Oil
Pressure warning light is illuminated
while the engine is running, severe
damage could result.
• If the warning light stays on while the
engine is running, it indicates that
there may be serious engine damage
or malfunction. In this case:
1. Stop the vehicle as soon as it is
safe to do so.
2. Turn off the engine and check the
oil level. If the oil level is low, fill
the engine oil to the proper level.
3. Start the engine again. If the
warning light stays on after the
engine is started, turn the engine
off immediately. If this occurs,
have the vehicle inspected by
an authorized retailer of Genesis
Branded products.
Engine coolant temperature
warning light (for 8-inch
cluster)
The warning light illuminates:
When the temperature of the engine
coolant is extremely high.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “Overheating” section
in chapter 8.
NOTICE
If the Engine Coolant Temperature
warning light illuminates, it indicates
overheating that may damage the
engine.
Low fuel level warning light
This warning light illuminates:
When the fuel tank is nearly empty.
Add fuel as soon as possible.
NOTICE
Driving with the Low Fuel Level warning
light on or with the fuel level below “E”
can cause the engine to misfire and
damage the catalytic converter.

Wiper
OJX1049008L
This indicator displays which wiper speed
is selected using the wiper control.
You can activate or deactivate Wiper/
Lights display function from the Settings
menu in the infotainment system screen.
Select:
-Setup → Vehicle Settings → Cluster
→ Content Selection → Wiper/Lights
Display
For detailed information, refer to the
separately supplied manual.
Low washer fluid
This message is displayed if the washer
fluid level in the reservoir is nearly empty.
Have the washer fluid reservoir refilled.
Low fuel
This message is displayed if the fuel tank
is almost out of fuel.
When this message is displayed, the low
fuel level warning light in the cluster will
come on.
It is recommended to look for the nearest
fueling station and refuel as soon as
possible.
Low engine oil (if equipped)
This warning message is displayed when
the engine oil level should be checked.
If this warning message is displayed,
check the engine oil level as soon as
possible and add engine oil as required.
Slowly pour the recommended oil little
by little into a funnel.
Use only the specified engine oil. (Refer
to "Recommended Lubricants and
Capacities“ section in chapter 2.)
Do not overfill the engine oil. Make sure
the oil level is not above F (Full) mark on
the dipstick.
Information
After adding engine oil, if you travel
approximately 31~62 miles (50~100 km)
after the engine warms up, the warning
message should disappear.

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, have the exhaust
system checked as soon as possible by an authorized retailer of Genesis Branded
products.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at “Fresh” and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and the fan
control set to high.
