Information
The fuel filler door will unlock when
Driver’s door is unlocked.
To unlock fuel filler door:
• Press the unlock button on your remote
key or smart key
• Press the Central Door unlock button
on armrest trim of driver’s door
The fuel filler door will lock when Driver’s
door is locked.
To lock fuel filler door:
• Press the lock button on your remote
key or smart key
• Press the Central Door lock button on
armrest trim of driver’s door
ÃAll doors will automatically lock after
the vehicle speed exceeds 9 mph. Fuel
filler door is also locked when vehicle
speed exceeds 9 mph.
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 deicer fluid (do not use
radiator antifreeze) 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.
Information
To lock the fuel filler door, make sure the
fuel filler door is completely closed. Press
the LOCK button on the remote key or
smart key to lock your vehicle. The fuel
filler door will also lock.
Note that if the fuel filler door is not
completely closed when the vehicle is
locked, the fuel filler door will not be
locked.
CAUTION
Make sure the fuel filler door is
completely closed before driving
through a car wash or operating a high
pressure spray washer.
WARNING
Automotive fuel 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 Gasoline 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 mobile phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire.

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. Shift the gear to 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.

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.
When installing new spark plugs, be sure
that the ignition coils are clean and free
of any oil or debris. Clean and wipe off
the bottom portion of the ignition coil in
order to prevent any contamination with
the spark plug during installation.
WARNING
Do not remove spark plugs from the
vehicle when the engine is hot. You
may damage the engine and may also
risk burn injury.
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.
Automatic Transmission Fluid
The automatic transmission fluid level
does not need to 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.

Maintenance

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
ONX4OB091019ONX4OB091019
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.
Turn the vehicle off and wait until the
engine cools down. Use extreme care
when removing the engine 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.
