RECOMMENDED LUBRICANTS AND CAPACITIES
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 SAE viscosity number
CAUTION
Always be sure to clean the area around any filler plug, 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.

then fold the seat toward the front of
the vehicle.

5. To use the rear seat, lift and push
the seatback rearward by lifting up
the front portion of the folding lever.
Push the seatback firmly until it clicks
into place. Make sure the seatback is
locked in place.
WARNING
When returning the rear seatback from
a folded to an upright position, hold the
seatback and return it slowly. Ensure
that the seatback is completely locked
into its upright position by pushing on
the top of the seatback. In an accident
or sudden stop, the unlocked seatback
could allow cargo to move forward with
great force and enter the passenger
compartment, which could result in
serious injury or death.
WARNING
Make sure the engine is off, the shift
lever is in P (Park), and the parking
brake is securely applied whenever
loading or unloading cargo. Failure to
take these steps may allow the vehicle
to move if the shift lever is inadvertently
moved to another position.
CAUTION
• Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.
• 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.

The air ventilation seats are provided
to cool the front seats by blowing air
through small vent holes on the surface
of the seat cushions and seatbacks.

NOTICE
To prevent damage to the air ventilation
seats:
• Never use a solvent such as paint
thinner, benzene, alcohol or gasoline
to clean the seats.
• Avoid spilling liquids on the surface
of the front seats and seatbacks; this
may cause the air vent holes to block
and not work properly.
• Do not place materials such as plastic
bags or newspapers under the seats.
They may block the air intake causing
malfunction of the air vent.
• Do not change the seat covers. It may
damage the air ventilation seat.
• If the air vents do not operate, restart
the vehicle. If there is no change,
have the vehicle inspected by an
authorized HYUNDAI dealer. •
Each time you push the switch, the
airflow changes as follows:
OFF
LOW ( )HIGH ( )

Rear Occupant Alert (ROA) (if
equipped)
Rear Occupant Alert is provided to
prevent a driver from leaving a vehicle
with a rear passenger left in the vehicle.
System setting
To use Rear Occupant Alert, it must be
enabled from the Settings menu in the
infotainment system screen. Select:
-Setup → Vehicle Settings → Convenience → Rear Occupant Alert
For detailed information, scan the QR
code in the separately supplied simple
manual.
System operation
• First alert
When you turn off the engine and
open the driver’s door after opening
and closing the rear door or liftgate,
the ‘Check rear seats’ warning
message appears on the cluster.
• Second alert
After the first alert, the second alert
operates when any movement is
detected in the vehicle after the
driver’s door is closed and all the
doors are locked. The horn will sound
for approximately 25 seconds. If
the system continues to detect a
movement, the alert operates up to 8
times.
Unlock the doors with the smart key
to stop the alert.
• The system detects movement in the
vehicle for 8 hours after the door is
locked.
• The second alert is activated only after
the prior activation of the first alert.
System precautions
• Make sure that all the windows are
closed. If the window is open, the
alert may operate by the sensor
detecting an unintended movement
(e.g. wind or bugs).
• „„Cluster„„Steering wheel
OTM048165LOCN7050079
If you do not want to use Rear
Occupant Alert, press the OK button
on the steering wheel when the first
alert is displayed on the cluster. Doing
so will deactivate the second alert one
time.
• An alert can occur if there is an impact
on the roof.
• If boxes or objects are stacked in the
vehicle, the system may not detect
the boxes or objects. Or, the alert may
operate if the boxes or objects fall off.
• The sensor may not operate normally
if the sensor is blocked with foreign
substances.
• The alert may operate if movement
in the driver or passenger seat is
detected.
• The alert may operate with the doors
locked due to car wash or surrounding
vibration or noise.
• If the vehicle is started remotely (if
equipped with Remote Start), inside
movement detection will stop.
• When the scheduled ventilation
function is in operation, inside
movement detection will stop.

NOTICE
The sensor that activates the SRS
control module is connected with the
pre–tensioner seat belts. The SRS air
bag warning light on the instrument
cluster will illuminate for approximately
3~6 seconds after the Engine Start/Stop
button is in the ON position, and then it
should turn off.
If the pre-tensioner is not working
properly, the warning light will
illuminate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminated
or illuminates when the vehicle is
being driven, we recommend the pre-
tensioner seat belts and/or SRS control
module be inspected by an authorized
HYUNDAI dealer as soon as possible.
Information
• Pre-tensioner seat belts may be
activated in certain frontal or side
collisions or rollover situations (if
equipped with rollover sensor).
• When the pre-tensioner seat belts are
activated, a loud noise may be heard
and fine dust, which may appear to be
smoke, may be visible in the passenger
compartment. These are normal
operating conditions and are not
hazardous.
• Although it is non-toxic, the fine dust
may cause skin irritation and should
not be inhaled for prolonged periods.
Wash all exposed skin areas thoroughly
after an accident in which the pre-
tensioner seat belts were activated.
Additional seat belt safety
precautions
Seat belt use during pregnancy
The seat belt should always be used
during pregnancy. The best way to
protect your unborn child is to protect
yourself by always wearing the seat belt.
Pregnant women should always wear
a lap-shoulder seat belt. Place the
shoulder belt across your chest, routed
between your breasts and away from
your neck. Place the lap belt below your
belly so that it fits SNUGLY across your
hips and pelvic bone, under the rounded
part of the belly.
WARNING
To reduce the risk of serious injury or
death to an unborn child during an
accident, pregnant women should
NEVER place the lap portion of the
seat belt above or over the area of the
abdomen where the unborn child is
located.
Seat belt use and children
Infant and small children
Most countries have Child Restraint
System laws which require children to
travel in approved Child Restraint System
devices, including booster seats. The age
at which seat belts can be used instead
of Child Restraint System differs among
countries, so you should be aware of the
specific requirements in your country,
and where you are travelling. Infant and
Child Restraint System must be properly
placed and installed in a rear seat.
For more information refer to the “Child
Restraint Systems” section in this
chapter.
