FUEL REQUIREMENTS
Petrol engine
Unleaded
Your new vehicle is designed to use only
unleaded fuel having an Octane Rating
of RON (Research Octane Number) 91 /
AKI (Anti-Knock Index) 87 or higher. (Do
not use methanol blended fuels)
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust
emissions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The use
of leaded fuel is detrimental to the
catalytic converter and will damage the
engine control system’s oxygen sensor
and affect emission control.
Never add any fuel system cleaning
agents to the fuel tank other than what
has been specified (We recommend
that you consult an authorized
HYUNDAI dealer for details.)
WARNING
• Do not “top off” after the nozzle
automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.

i Information
• The fuel tank capacity is given in
chapter 2.
• The fuel gauge is supplemented by
a low fuel warning light, which will
illuminate when the fuel tank is nearly
empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
WARNING
Running out of fuel can expose vehicle
occupants to danger.
You must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the “E
(Empty)” level.
NOTICE
Avoid driving with a very low fuel
level. Running out of fuel could cause
the engine to misfire damaging the
catalytic converter.

1. Turn the engine off.
2. Ensure the driver’s door is unlocked.
3. Push the fuel filler door gently on
the “markings” (near the 3o‘clock
position.)
OBI3050016OBI3050016
3. Pull the fuel filler door out (1) to fully
open.
4. To remove the fuel tank cap (2), turn
it counterclockwise. You may hear a
hissing noise as the pressure inside
the tank equalizes.
5. Place the cap on the fuel filler door (3).
WARNING
• Your diesel vehicle is equipped with
the specially-designed breakaway
valve inside the filler inlet to prevent
accidental fuel blending with petrol.
The fuel inlet of your diesel vehicle
cannot be fitted with a standard
petrol nozzle. Do not forcefully insert
a standard petrol nozzle into the filler
inlet of your diesel vehicle. It may
damage your vehicle.
• Some gas stations may still use
standard petrol nozzles for diesel
refueling. If you find that a diesel
nozzle is narrower than the fuel
filler inlet diameter of your diesel
vehicle, we recommend you to find/
visit another gas station, which
is equipped with standard diesel
nozzles.
• Fully insert a standard diesel nozzle
into the filler inlet to open the
breakaway valve. If the nozzle is not
fully inserted into the filler inlet, it
causes diesel fuels to flow out of the
fuel tank.
i 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 de-icer fluid (do not use
radiator anti-freeze) or move the vehicle
to a warm place and allow the ice to melt.

Convenient features
Closing the fuel filler door
1. To install the fuel tank cap (2), turn it
clockwise until it “clicks” once. This
indicates that the cap is securely
tightened.
2. Close the fuel filler door (1) and push it
lightly and make sure that it is securely
closed.
WARNING
Petrol 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 Petrol 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 buildup 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 petrol source, with your bare
hand.
• 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 petrol.

• When refueling, always move the
shift lever to the P (Park) position (for
Intelligent Manual Transmission) 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.
• Do not over-fill or top-off your
vehicle tank, which can cause petrol
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.i Information
• Make sure to refuel your vehicle
according to the “Fuel Requirements”
suggested in the 1 chapter.
• Do not spill fuel on the exterior surfaces
of the vehicle. Any type of fuel spilled
on painted surfaces may damage the
paint.
NOTICE
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.

Maintenance
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes are
required.
Drive belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked
periodically for proper tension and
adjusted as necessary.
NOTICE
When you are inspecting the belt, place
the ignition switch in the LOCK/OFF or
ACC position.
Fuel filter
A clogged filter can limit the speed
at which the vehicle may be driven,
damage the emission system and cause
multiple issues such as hard starting.
If an excessive amount of foreign
matter accumulates in the fuel tank, the
filter may require replacement more
frequently.
After installing a new filter, run the
engine for several minutes, and check
for leaks at the connections.
We recommend that the fuel filter be
replaced by an authoized HYUNDAI
dealer.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend that the fuel lines, fuel
hoses and connections be replaced by
an authoized HYUNDAI dealer.
WARNING
Diesel Engine
Never manipulate or modify the
injection system while running the
diesel engine or within 30 seconds
after turning OFF the diesel engine. The
high-pressure pump, high-pressure
pipes, rail, and injectors are still subject
to high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out, it
may cause serious body injury. Any
people, who are implanted with the
artificial cardiac pacemaker, should
remain away from the ECU or the
wiring harness by at least 30 cm,
while running the diesel engine. The
high currents of the electronic engine
control system produce a considerable
amount of magnetic fields.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
