Owner maintenance schedule
When you stop for fuel:
• Check the coolant level in the engine
coolant reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated tires.
WARNING
Be careful when checking your coolant
level when the engine is hot. This may
result in coolant being blown out of the
opening and cause serious burns and
other injuries.
While operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.
• Check the automatic transmission P
(Park) function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.

ENGINE OIL
Checking the engine oil level
Engine oil is used for lubricating,
cooling, and operating various hydraulic
components in the engine. Engine oil
consumption while driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.
Gasoline engine
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and warm
the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to return
to the oil pan.
5. Wipe the dipstick clean and re-insert
it fully.

ENGINE COOLANT
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
„„Smartstream G2.5 GDI
ONX4E090049
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, we
recommend that you 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.
Turn the vehicle off and wait until the
engine cools down. Use extreme care
when removing the engine coolant
cap and/or water-cooled intercooler
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.
Information
The coolant level is influenced by the
engine temperature. Before checking or
refilling the coolant, turn the engine off.

WARNING
The electric motor for the cooling fan may continue to operate or start up
when the engine is not running and
can cause serious injury. Keep hands,
clothing and tools away from the
rotating fan blades of the cooling fan.
Always turn off the vehicle unless the
vehicle has to be inspected with the
engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while
driving.

WARNING
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of SERIOUS
INJURY or DEATH, take the
following precautions:
• Inspect your tires monthly for
proper inflation as well as wear
and damage.
• The recommended cold tire
pressure for your vehicle can be
found in this manual and on the
tire label located on the driver’s
side center pillar. Always use a
tire pressure gauge to measure
tire pressure. Tires with too
much or too little pressure wear
unevenly causing poor handling.
• Check the pressure of the
spare every time you check the
pressure of the other tires on
your vehicle.
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, or traction.
• ALWAYS replace tires with the
same size, type, construction and
tread pattern as each tire that
was originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended
tire inflation pressures and stay
within the load limits and weight
distribution recommended for your
vehicle.
ONX4E010022
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
Recommended cold tire inflation
pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold tires” means the
vehicle has not been driven for at
least three hours or driven less than 1
mile (1.6km).
Warm tires normally exceed
recommended cold tire pressures
by 4 to 6 psi (28 to 41 kPa). Do not
release air from warm tires to adjust
the pressure or the tires will be
under-inflated. For recommended
inflation pressure, refer to “Tire and
Wheels” section in chapter 2.
TIRES AND WHEELS

09
9-39
Wheel alignment and tire
balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can damage
your vehicle’s aluminum wheels. Use
only approved wheel weights.
Tire replacement
Tread wear indicatorTread wear indicator
OHI078080
If the tire is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This shows
there is less than 1/16 inch (1.6mm) of
tread left on the tire. Replace the tire
when this happens.
Do not wait for the band to appear
across the entire tread before
replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and traction.
• Always replace tires with the
same size as each tire that was
originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.
• When replacing tires (or wheels),
it is recommended to replace
the two front or two rear tires (or
wheels) as a pair. Replacing just
one tire can seriously affect your
vehicle’s handling.
• Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tires be replaced after six (6)
years of normal service.
• Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.
