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.

b) Refer to “Fuel Requirements” in the
Introduction chapter.
*1 : Refer to the recommended SAE viscosity numbers on the next page.
*2 : For the best performance of braking and ABS/ESC functions, you should use genuine
brake fluid that conform to standards. (Standards: SAE J1704 DOT-4 LV, ISO4925 CLASS-6
and FMVSS116 DOT-4)
*3 : 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.
*4 : Requires < API SN PLUS (or above) Full synthetic> grade engine oil. If a lower grade
engine oil (mineral oil including Semi-synthetic) is used, then the engine oil and engine
oil filter must be replaced as indicated severe maintenance condition.

Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on the
door. If necessary, spray around the door
with an approved de-icer fluid (do not use
radiator anti-freeze) or move the vehicle to
a warm place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn it clockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.
WARNING
Gasoline is highly flammable and
explosive. Failure to follow these
guidelines may result in SERIOUS
INJURY or DEATH:

[Read and follow all warnings posted
at the gas station.

[ Before refueling, note the location
of the Emergency Fuel Shut-Off, if
available, at the gas station.

[ Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.

[ Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire.
[
Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other fuel source, with your bare
hand.

[ When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire.
Once refueling has begun, contact
between your bare hand and the
vehicle should be maintained until
the filling is complete.

[ Use only approved portable plastic
fuel containers designed to carry and
store fuel.

[ When refueling, always shift the
gear to the P (Park) position, set
the parking brake, and press the
Engine Start/Stop button to the
OFF position. Sparks produced by
electrical components related to the
engine can ignite fuel vapors causing
a fire.

[ Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake. If the air
conditioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury. 4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.
WARNING
Never remove the engine
coolant cap and/or water-
cooled intercooler coolant
cap or the drain plug while the
engine and radiator are hot.
Hot coolant and steam may blow out
under pressure, causing serious injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the coolant cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure is
released from the cooling system. When
you are sure all the pressure has been
released, press down on the cap, using
a thick towel, and continue turning
counterclockwise to remove it.

The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the
factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season and
before traveling to a colder climate.
Checking the Coolant Level
OOSN091003L
OOSN091004L
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled
between the MAX and the MIN marks on
the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the MAX mark, but do not overfill.
If frequent additions are required, see an
authorized HYUNDAI dealer for a cooling
system inspection.
WARNING
Never remove the engine
coolant cap and/or water-
cooled intercooler coolant
cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may blow out under pressure,
causing serious injury.
