F6
Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you use unleaded
gasoline which has an octane rating of
RON (Research Octane Number) 95 /
AKI (Anti Knock Index) 91 or higher.
You may use unleaded gasoline with
an octane rating of RON 91-94 / AKI
87-90 but it may result in slight per-
formance reduction of the vehicle. (Do
not use methanol blended fuels)
Except Europe
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 mini-
mize exhaust emissions and spark
plug fouling.
NOTICE
•Do not "top off" after the noz-
zle automatically shuts off
when refueling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
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 speci-
fied (We recommend that you
consult an authorized HYUNDAI
dealer for details.)

Closing the fuel filler door
1. To install the fuel tank cap, turn itclockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.
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 noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand. (Continued)
WARNING
(Continued)
When refueling, always move
the shift lever to the P (Park)
position (for automatic transmis-
sion/
dual clutch 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.
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.
(Continued)
(Continued)
Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by touch-
ing, 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 danger-
ous 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.(Continued)

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)
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 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.
(Continued)
(Continued)
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 prevent
fuel spillage in the event of an
accident.

Convenient features of your vehicle
Fuel gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given inchapter 8.
• 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. Avoid driving with a extremely low
fuel level. Running out of fuel
could cause the engine to misfire
damaging the catalytic converter.
NOTICE
i
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pressure
and could severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.
WARNING
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "0" level.

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 peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (cartridge)
A clogged-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the
hard starting. When a considerable
amount of foreign substances are
accumulated in the fuel tank, the fuel
filter should be replaced.
Upon installing a new fuel filter, oper-
ate the diesel engine for several min-
utes, and check the connections for
any leakages. We recommend you to
have the fuel filter replaced by an
authorized HYUNDAI dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorized HYUNDAI
dealer.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
When you are inspecting the belt,
place the ignition switch to the
LOCK/OFF or ACC position.
