Diesel engine
Diesel fuel
Diesel engine must be operated only on
commercially available diesel fuel that
complies with EN 590 or comparable
standard. (EN stands for “European
Norm”). Do not use marine diesel fuel,
heating oils, or non-approved fuel
additives, as this will increase wear and
cause damage to the engine and fuel
system. The use of non-approved fuels
and / or fuel additives will result in a
limitation of your warranty rights.
Diesel fuel of above cetane 51 is used
in your vehicle. If two types of diesel
fuel are available, use summer or winter
fuel properly according to the following
temperature conditions.
• Above -5°C (23°F) ... Summer type
diesel fuel.
• Below -5°C (23°F) ... Winter type diesel
fuel.
Watch the fuel level in the tank very
carefully : If the engine stop s through
fuel failure, the circuits must be
completely purged to permit restarting.
CAUTION
Do not let any petrol or water enter the
tank. This would make it necessary to
drain it out and to bleed the lines to
avoid jamming the injection pump and
damaging the engine.
CAUTION
Diesel Fuel (if equipped with DPF)
It is recommended to use the regulated
automotive diesel fuel for diesel vehicle
equipped with the DPF system.
If you use diesel fuel including high
sulfur (more than 50 ppm sulfur) and
unspecified additives, it can cause the
DPF system to be damaged and white
smoke can be emitted.
Biodiesel
Commercially supplied Diesel blends of
no more than 7% biodiesel, commonly
known as “B7 Diesel” may be used
in your vehicle if Biodiesel meets EN
14214 or equivalent specifications. (EN
stands for “European Norm”). The use
of biofuels exceeding 7% made from
rapeseed methyl ester (RME), fatty
acid methyl ester (FAME), vegetable oil
methyl ester (VME) etc. or mixing diesel
exceeding 7% with biodiesel will cause
increased wear or damage to the engine
and fuel system. Repair or replacement
of worn or damaged components due to
the use of non approved fuels will not be
covered by the manufactures warranty.
CAUTION
• Never use any fuel, whether diesel,
B7 biodiesel or otherwise, that fails
to meet the latest petroleum industry
specification.
• Never use any fuel additives
or treatments that are not
recommended or approved by the
vehicle manufacturer.

OBI3040006OBI3040006
This gauge shows the temperature of the
engine coolant when the ignition switch
is in the ON position.
NOTICE
If the gauge pointer moves beyond the
normal range area toward the “130”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “If the Engine
Overheats” in chapter 8.
WARNING
Never remove the radiator cap or
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could cause severe burns. Wait
until the engine is cool before adding
coolant to the reservoir.

Smart key precautions
The smart key will not work if any of the
following occur:
• The smart key is close to a radio
transmitter such as a radio station,
military area, police station,
government offices, broadcasting
stations, transmission towers, port or
an airport which can interfere with
normal operation of the smart key.
• The smart key is near a mobile two
way radio system or a cellular phone.
• The smart key is close to a metal
product or coins
• Another vehicle’s smart key is being
operated close to your vehicle.
• When you connect an external device
to the multi-purpose socket or USB
port and place it near the smart key,
the smart key may not be recognized/
work in some areas of the vehicle. In
this case, try moving the smart key to
another location to start the engine or
press the start button directly with the
smart key to start the engine.
In the following situations, the frequency
band from the smart key may be mixed
with a different frequency, which may
cause smart key malfunction (engine
operation, door lock function, etc.) or
the working distance of smart key may
change.
• The smart key is placed near the
electronic systems (woofer, cellular
phone, portable wired/wireless
charger, electric heating device,
electronic power bank, e-cigarettes,
etc.)
When the smart key does not work
correctly, open and close the door
with the mechanical key. If you have
a problem with the smart key, it is
recommended that you contact an
authorized HYUNDAI dealer.
If the smart key is in close proximity to
your mobile phone, the signal could be
blocked by your mobile phones normal
operational signals. This is especially
important when the phone is active
such as making and receiving calls, text
messaging, and/or sending/receiving
emails. Avoid placing the smart key and
your mobile phone in the same pants or
jacket pocket and always try to maintain
an adequate distance between the two
devices.
i Information
Changes or modifications not expressly
approved by the party responsible
for compliance could void the user’s
authority to operate the equipment. If the
keyless entry system is inoperative due
to changes or modifications not expressly
approved by the party responsible for
compliance, it will not be covered by your
manufacturer’s vehicle warranty.
NOTICE
Keep the smart key away from
electromagnetic materials that blocks
electromagnetic waves to the key
surface.

Recirculation mode
The indicator light on the
button illuminates when
the recirculated air
position is selected.
With the recirculated air
position selected, air from
the passenger
compartment will be
drawn through the climate
control system and heated
or cooled according to the
function selected.
Fresh mode
The indicator light on the
button will turn off when
the outside (fresh) air
position is selected.
With the outside (fresh) air
position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
i Information
Prolonged use of the air conditioning
with the recirculated air position selected
will result in excessively dry air in the
passenger compartment.
WARNING
• 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 resulting 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 air
conditioning or heating system on. It
may cause serious harm or death due
to a drop in the oxygen level and/or
body temperature.

• 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.
i 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.
