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 un til it “clicks” one time.
2.
 Close the fuel filler door until it is 
la
tched securely.

Make the vehicle door to LOCK position 
and the fuel filler door completely closed 
in order to lock the fuel filler door.
If the fuel filler door is not completely 
closed, the fuel filler door will not be 
locked.
 CAUTION
Keep the door into LOCK position when 
the vehicle is being washed (i.e. high 
pressure washer, automatic car washer, 
etc.)
 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 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 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 r
oad and stop as soon as it 
is safe to do so.
2.
 Shift the gear to P (P
ark) and set the 
parking brake. If the air conditioning is 
ON, turn it OFF.
3.
 If engine coolant is running out under 
the v
ehicle 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 coolan
t 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, s
 top 
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.
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.
