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.

*1 : Refer to the recommended SAE viscosity numbers on the next page.
*2 : To maintain the best braking performance and ABS/ESC performance, we recommend
that you use fluid that conform to specifications.
*3 : If the front/rear differential is submerged, visit an authorized retailer of Genesis Branded
products to replace the differential oil.
*4 : If the above recommended specification oil is not available, SAE 0W-30 grade synthetic
oil can be used. If mineral oil or semi-synthetic oil is used, it is a severe maintenance
condition in terms of engine oil change
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.

Engine Oil
*10W-300W-30
*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.

• When sudden braking or sharp turning
occurs, Pre-active Safety Seat will
tighten the seat belt to prevent the
passenger from leaning forward or
sideway and provide driving stability.
In the following circumstances, the
system will consider it as a hazardous
situation and the system will operate
when:
-The passenger leans forward due to
sudden braking
-The passenger leans sideway due to
sharp turning
-Driving on slippery roads
-Driving in off-road conditions
-High risk of rollover is detected
• If the seat is manually adjusted while
Pre-active Safety Seat is operating,
the system will immediately stop
operating. However, after 5 seconds,
if a possible collision or hazardous
situation is detected, the system will
operate again.
System malfunction
When the Pre-active Adjustment Seat
system does not operate properly, have
the vehicle inspected by an authorized
retailer of Genesis Branded products.
Rear Seats
WARNING
NEVER adjust the rear power seats
when a Child Restraint System is
installed in that seat.
WARNING
To prevent injury:
• Do not adjust your seat while
wearing your seat belt. Moving the
seat cushion forward may cause
strong pressure on your abdomen.
• Do not allow your hands or fingers to
get caught in the seat mechanisms
while the seat is moving.
NOTICE
To prevent damage to the seats:
• Always stop adjusting the seats when
the seat has been adjusted as far
forward or rearward as possible.
• Do not adjust the seats longer than
necessary when the engine is turned
off. This may result in unnecessary
drain of the battery.
• Do not operate two or more seats at
the same time. This may result in an
electrical malfunction.

Carrying long/narrow cargo
ORG3030009N
Additional cargo space is provided to
accommodate long/narrow cargo (skis,
poles, etc.) not able to fit properly in the
trunk when closed.
1. Pull the armrest down.
2. Pull the cover down while pushing the
release lever down.
NOTICE
• Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.
• When both the armrest and the
panel, which is locates between
the rear seatback and the trunk, are
folded down, put back the panel first
before folding back the arm rest. If
not, the panel knobs and the armrest
knobs may interfere with each other
and get damaged.
CAUTION
• Make sure the engine is off, the
vehicle is shifted to P (Park) and the
parking brake is applied whenever
loading or unloading cargo. The
vehicle may move if the shift lever
is inadvertently moved to another
position.
• When cargo is loaded through the
rear passenger seats, ensure the
cargo is properly secured to prevent
it from moving while driving.
WARNING
Cargo should always be secured to
prevent it from being thrown about the
vehicle in a collision and causing injury
to the vehicle occupants. Do not place
objects in the rear seats, since they
cannot be properly secured and may hit
the front seat occupants in a collision.

Safety System
3-20
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.
Front seat warmers
OJX1039053L
• While the engine is running, touch
either of the seat warmer icons
to warm the driver’s seat or front
passenger’s seat.
• Manual temperature control
Each time you touch the icon, the
temperature setting of the seat is
changed as follows :
OFF → HIGH ( ) → MIDDLE ( ) → LOW ( )
• Automatic temperature control
The seat warmer starts to
automatically control the seat
temperature in order to prevent
low temperature burns after being
manually turned ON.
OFF → HIGH ( ) → MIDDLE ( ) → LOW ( )
30 min 60 min
You may manually touch the icon to
increase seat temperature. However,
the seat temperature is automatically
adjusted again.

• Seat Heater Balance
You may lower the seat warmer
setting, or may turn the seat warmer
off for either the seatback or seat
cushion, when the seat warmer is on.
To use this function, it must be
enabled from the Settings menu in the
infotainment system screen. Select:
-Setup -> Vehicle Settings -> Seat -> Heated/Ventilated Features -> Seat Heater Balance
• When touching the icon for more than
1.5 seconds with the seat warmer
operating, the seat warmer will turn
OFF.
• The seat warmer defaults to the OFF
position whenever the Engine Start/
Stop button is pressed to the ON
position.
Rear seat warmers (if equipped)
ORG3030011
• While the engine is running, press
either of the seat warmer switches to
warm the rear seat.
• Manual temperature control
Each time you press the switch, the
temperature setting of the seat is
changed as follows :
OFF → HIGH ( ) → MIDDLE ( ) → LOW ( )
