Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exteriorsurfaces of the vehicle. Any type
of fuel spilled on painted sur-
faces 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.
NOTICE
i(Continued)
Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact 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 com-
pletely removing the cap.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
(Continued)
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.
When refueling, always move
the shift lever to the P (Park)
position (for automatic transmis-
sion
) or first gear or R (Reverse,
for manual transmission), 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.
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.

In this case, have the vehicle
inspected by an authorized
HYUNDAI dealer as soon as possi-
ble.

Operation Tips
To keep dust or unpleasant fumesfrom entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Return the
control to the fresh air position
when the irritation has passed.
This will help keep the driver alert
and comfortable.
To help prevent the inside of the windshield from fogging, set the air
intake control to the fresh air posi-
tion and fan speed to the desired
position, turn on the air conditioning
system, and adjust the temperature
control to the desired temperature.
Air conditioning
All HYUNDAI Air Conditioning
Systems are filled with environmen-
tally friendly R-1234yf refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Level mode.
4. Set the air intake control to the recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position then set the fan
speed control to the highest speed. When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic when
outside temperatures are high. Air
conditioning system operation can
cause engine overheating.
Continue to use the fan, but turn
the air conditioning system off if
the engine temperature gauge
indicates engine overheating.

by pushing the fan speed control
knob.
More air is delivered with higher fan
speeds.
Pressing the OFF button turns off the
fan.
Information
For better sound quality, fan speed
may automatically slow down for a
couple of minutes when you activate
voice recognition or hands free.

OYC046317
Continued use of the climate
control system operation in
the recirculated air position
can cause drowsiness or
sleepiness, that may cause
loss of vehicle control result-
ing in an accident. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.
Continued use of the climate
control system operation in
the recirculated air position
(without the air conditioning
selected) may allow humidity
to increase inside the vehicle
which may fog the glass and
obscure visibility.
Do not sleep in a vehicle with
the air conditioning or heating
system on. It may cause seri-
ous injury or death due to a
drop in the oxygen level
and/or body temperature.
