Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “Clicks”.
2. Close the fuel filler door until it is
latched securely.
Tighten the cap until it clicks one time,
otherwise the Check Engine (
) light will illuminate.
NOTICE
There may be an intermittent noise
near the refueling hole while the engine
is idling if the fuel cap is not closed
securely. This occurs normally with the
OBD system.
NOTICE
When refueling on unlevel ground,
the fuel gauge may not point to the F
position.
It is not a malfunction. If you move your
vehicle to a level ground, the fuel gauge
will move to the full position.
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 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 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 build-up 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 gasoline source, with your
bare hand.

• When refueling, always move the
shift lever to the P (Park) position,
set the parking brake, and place the
ignition switch to the LOCK/OFF
position.
• Sparks produced by electrical
components related to the engine
can ignite fuel vapors causing a fire.
• 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 gasoline.
• 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.
• Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
• If a fire breaks out during refueling,
leave the vicinity of the vehicle, and
immediately contact the manager
of the gas station and then contact
the local fire department. Follow any
safety instructions they provide.• If pressurized fuel sprays out, it can
cover your clothes or skin and thus
subject you to the risk of fire and
burns. Always remove the fuel cap
carefully and slowly. If the cap is
venting fuel or if you hear a hissing
sound, wait until the condition stops
before completely removing the cap.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
Information
Make sure to refuel your vehicle according
to the “Fuel Requirements” suggested in
the Introduction chapter.
NOTICE
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces may
damage the paint.
• If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can result
in a serious malfunction of the fuel
system or emission control system.

Battery saver function
The purpose of this feature is to
help prevent the battery from being
discharged. The system automatically
turns off the parking lamp when the
driver turns the vehicle off and opens the
driver-side door.
With this feature, the parking lamps will
turn off automatically if the driver parks
on the side of road at night.
If necessary, to keep the lamps on when
the vehicle is turned off, perform the
following:
(1) Open the driver-side door.
(2) Turn the parking lamps OFF and ON
again using the headlamp switch on
the steering column.
Headlamp delay function
(if equipped)
If you place the ignition switch in the
ACC or OFF position with the headlamps
ON, the headlamps (and/or parking
lamps) remain on for about 5 minutes.
However, with the engine off if the
driver’s door is opened and closed, the
headlamps (and/or parking lamps) are
turned off after 15 seconds.
The headlamps (and/or parking lamps)
can be turned off by pressing the lock
button on the remote key or smart key
twice or turning the light switch to the
OFF or AUTO position. However, if you
turn the light switch to the AUTO position
when it is dark outside, the headlamps
will not be turned off.
You can activate or deactivate the
Headlamp Delay function from the User
Settings Mode in the LCD display.
For more details, refer to “LCD Display
Modes” in chapter 4. If your vehicle is
equipped with additional navigation,
please refer to the infotainment system
manual separately supplied.
NOTICE
If the driver exits the vehicle through
another door besides the driver
door, the battery saver function
does not operate and the headlamp
delay function does not turn OFF
automatically.
This may cause the battery to
discharge. To avoid battery discharge,
turn OFF the headlamps manually from
the headlamp switch before exiting the
vehicle.

Air intake control
Recirculated air position
With the recirculated air position selected, air from the
passenger compartment will
be drawn through the heating
system and heated or cooled
according to the function
selected.
Outside (fresh) air position
With the outside (fresh) air
position selected, air enters
the vehicle from outside and
is heated or cooled according
to the function selected.
Information
Operating the system primarily in Fresh
mode is recommended. Use Recirculation
mode temporarily only when needed.
Prolonged operation of the heater in
Recirculation mode and without the A/C
ON can cause fogging of the windshield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result in
excessively dry, dehumidified air in the
cabin and may promote formation of
musty vent odor due to stagnant air.
WARNING
• Continued use of the climate control
system operation in Recirculation
mode for a prolonged period of
time may cause drowsiness to the
occupants in the cabin. This may lead
to loss of vehicle control which may
lead to an accident.
• Continued use of the climate control
system operation in Recirculation
mode with the A/C OFF may allow
humidity to increase inside the cabin.
This may cause condensation to
accumulate on the windshield and
obscure visibility.
• Do not sleep in your vehicle or
remain parked in your vehicle with
the windows up and either the
heater or the air conditioning ON for
prolonged periods of time. Doing so
may increase the levels of carbon
dioxide in the cabin which may lead
to serious injury or death.
Fan speed control
OCN7050118
The fan speed can be set to the desired
speed by using the fan speed control
toggle switch.
More air is delivered with higher fan
speeds.
Pressing the OFF button turns off the fan.
NOTICE
Operating the fan speed when the
ignition switch is in the ON position
could cause the battery to discharge.
Operate the fan speed when the engine
is running.

find out which air conditioning refrigerant
is applied to your vehicle on the label
located inside of the hood.
NOTICE
• The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.
• The refrigerant system should be
serviced in a well-ventilated place.
• The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.
Information
• When using the air conditioning
system, monitor the temperature
gauge closely while driving up hills
or in heavy traffic when outside
temperatures are high. Air conditioning
system operation may cause engine
overheating. Continue to use the blower
fan but turn the air conditioning system
off if the temperature gauge indicates
engine overheating.
• When opening the windows in humid
weather, air conditioning may create
water droplets inside the vehicle. Since
excessive water droplets may cause
damage to electrical equipment, air
conditioning should only be used with
the windows closed.
