To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

RECOMMENDED LUBRICANTS AND CAPACITIES

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.

Electric Power Steering (EPS)
warning light
This warning light illuminates:
• When you set the Engine Start/Stop
button to the ON position.
-The electric powering steering
warning light illuminates for about 3
seconds and then goes off.
• Whenever there is a malfunction with
the electric power steering.
If this occurs, have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
Charging system warning
light
This warning light illuminates:
When there is a malfunction with either
the alternator or electrical charging
system.
If there is a malfunction with either the
alternator or electrical charging system:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
alternator drive belt for looseness or
breakage.
If the belt is adjusted properly, there
may be a problem in the electrical
charging system.
If this occurs, have the vehicle
inspected by an authorized retailer of
Genesis Branded products as soon as
possible.
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 9). 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.
Continued driving with the warning
light on may cause engine failure.
Information
3.5T-GDI, 3.5T-GDI 48 V MHEV
When engine oil pressure decreases due to
insufficient engine oil, etc., the Engine Oil
Pressure warning light will illuminate. In
addition, the enhanced engine protection
system which limits engine power will
be activated. If the engine oil pressure is
restored, the Engine Oil Pressure warning
light and the enhanced engine protection
system will turn off.
However, when the engine oil pressure
is restored, the warning light and the
enhanced engine protection system will
turn off after the engine is restarted.
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.

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.
Malfunction Indicator Lamp
(MIL)
This indicator light illuminates:
• When you set the Engine Start/Stop
button to the ON position.
-The malfunction indicator light
illuminates for about 3 seconds and
then goes off.
• Whenever there is a malfunction with
either the emission control system or
the engine or the vehicle powertrain.
If this occurs, have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
NOTICE
• Driving with the Malfunction
Indicator Lamp (MIL) on may cause
damage to the emission control
system which could affect drivability
and/or fuel economy.
• For 3.5T-GDI, 3.5T-GDI 48 V MHEV
If the enhanced engine protection
system becomes activated due to
lack of engine oil, engine power
will be limited. If such condition
continues repeatedly, the
Malfunction Indicator Lamp will
illuminate.
NOTICE
If the Malfunction Indicator Lamp
(MIL) illuminates, potential catalytic
converter damage is possible which
could result in loss of engine power. If
this occurs, have the vehicle inspected
by an authorized retailer of Genesis
Branded products as soon as possible.

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.
Engine overheated
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
“Overheating” section in chapter 8.
Check haptic steering wheel system
This message is displayed if there is a
problem with the haptic steering wheel
system. Have the vehicle inspected by an
authorized retailer of Genesis Branded
products.
Check headlight (if equipped)
This message is displayed if the
headlights are not operating properly. A
lamp may need to be replaced.
Make sure to replace the burned out
bulb with a new one of the same wattage
rating.
Check turn signal (if equipped)
This message is displayed if the turn
signal lamps are not operating properly.
A lamp may need to be replaced.
Make sure to replace the burned out
bulb with a new one of the same wattage
rating.

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.
