6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost,
carefully add coolant to the reservoir
to bring the fluid level in the reservoir
up to the halfway mark.
7.
Proceed with caution, k

eeping alert
for further signs of overheating.
If overheating happens again,
we recommend that you call an
authorized HYUNDAI dealer for
assistance. CAUTION
• Serious loss of coolant indicates a
leak in the cooling system and we
recommend the system be checked
by an authorized HYUNDAI dealer.
• When the engine overheats from
low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities. It may require several
refilling cycles to properly fill the
engine cooling system. If necessary,
an authorized HYUNDAI dealer
should be consulted to perform this
task.

Maintenance
9-6
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check the coolant level in the engine
coolant reservoir or the water-cooled
intercooler 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.
At least twice a year: (i.e., every
Spring and Autumn)
• Check radiator, heater and air
conditioning hoses for leaks or
damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields
and clamps.
• Check the seat belts for wear and
function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood
hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate automatic
transmission linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.

Air cleaner filter
We recommend that the air cleaner filter
be replaced by an authorized HYUNDAI
dealer.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Engine coolant/water-cooled
intercooler coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid be changed by an
authorized HYUNDAI dealer according to
the maintenance schedule.
Information
Automatic transmission fluid color is red
when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the color
change.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction and
failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended Lubricants and
Capacities” section in chapter 2.)
Dual clutch transmission fluid (if
equipped)
Inspect the dual clutch transmission fluid
according to the maintenance schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX marks
on the side of the reservoir. Use only
hydraulic brake fluid conforming to DOT
4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.

EngInE COOLAnT /LIQUID-COOLED InTERCOOLER
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
OTMA090004
„„Smartstream G2.5 T-GDI
OTMA090018
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.

Maintenance
9-20
Recommended coolant
• When adding coolant, use only
deionized water, distilled water or soft
water for your vehicle and never mix
hard water in the coolant filled at the
factory.
• An incorrect coolant mixture can
result in severe malfunction or engine
damage.
• The engine in your vehicle has
aluminum engine parts and must be
protected by an phosphate-based
ethylene glycol coolant to prevent
corrosion and freezing.
• Do not use alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixing percentage, refer to the
following table:
Ambient
Temperature Mixture Percentage
(volume)
Antifreeze Water
5°F (-15°C) 35 65
-13°F (-25°C) 40 60
-31°F (-35°C) 50 50
-49°F (-45°C) 60 40
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of -31°F
(-35°C) and higher.
Changing coolant
We recommend that coolant be changed
by an authorized HYUNDAI dealer
according to the Maintenance Schedule
at the beginning of this chapter.
WARNING
Do not use engine coolant or antifreeze
in the washer fluid reservoir.
Engine coolant can severely obscure
visibility when sprayed on the
windshield and may cause loss of
vehicle control resulting in an accident.
Engine coolant may also cause damage
to paint and body trim.
NOTICE
To prevent damage to engine parts, put
a thick towel around the engine coolant
cap and/or inverter coolant cap before
refilling the coolant to prevent the
coolant from overflowing into engine
parts, such as the alternator.

WASHER FL UID
Checking the washer fluid level
OTMA090006
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold
climates to prevent freezing.
WARNING
To prevent serious injury or death, take
the following safety precautions when
using washer fluid:
• Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility when
sprayed on the windshield and
may cause loss of vehicle control
resulting in an accident or damage to
paint and body trim.
• Do not allow sparks or flame to
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol and can be
flammable.
• Do not drink washer fluid and avoid
contact with skin. Washer fluid is
harmful to humans and animals.
• Keep washer fluid away from
children and animals.
