The use of leaded fuel is detri-
mental 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 spec-
ified. We recommend that you
consult an authorised HYUNDAI
dealer for details.

Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “clicks” one time.
2. Close the fuel filler door until it is
latched securely.
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 service station.
•Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the service 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 fuel
source, with your bare hand.

•Do not use mobile phones
whilst refuelling. Electric cur-
rent and/or electronic interfer-
ence from mobile phones can
potentially ignite fuel vapours
and cause a fire.
•Do not get back into a vehicle
once you have begun refu-
elling. 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
vapours causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other fuel source,
with your bare hand.

•When refuelling, always move
the shift lever to the P (Park)
position (for automatic trans-
mission) or first gear or R
(Reverse, for manual trans-
mission), set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components related
to the engine can ignite fuel
vapours causing a fire.
•When using an approved
portable fuel container, be
sure to place the container on
the ground prior to refuelling.
Static electricity discharge
from the container can ignite
fuel vapours causing a fire.
Once refuelling has begun,
contact between your bare
hand and the vehicle should
be maintained until the filling
is complete.

Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
•Do not spill fuel on the exterior
surfaces 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)
•If pressurised 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)
•Use only approved portable
plastic fuel containers
designed to carry and store
petrol.
•Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle whilst at a service sta-
tion, especially during refu-
elling.
•Do not over-fill or top-off your
vehicle tank, which can cause
petrol spillage.
•If a fire breaks out during refu-
elling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the serv-
ice station and then contact
the local fire department.
Follow any safety instructions
they provide.

Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given in
chapter 8.
• A low fuel level also is indicated 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 an 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
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.

Running out of fuel can expose
vehicle occupants to danger.
Yo u m u s t s t o p a n d o b t a i n a d d i -
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "E (Empty)"
level.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, 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 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 authorised 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 authorised HYUNDAI
dealer.
Va p o u r h o s e a n d f u e l f i l l e r c a p
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapour hose or fuel filler cap is cor-
rectly replaced.
When you are inspecting the
belt, place the ignition switch to
the LOCK/OFF or ACC position.

Maintenance
•Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
we recommend that the tyres
be checked by an authorised
HYUNDAI dealer.
•Overinflation produces a
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.
CAUTION
•Warm tyres normally exceed
recommended cold tyre pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air from
warm tyres to adjust the pres-
sure or the tyres will be
underinflated.
•Be sure to reinstall the tyre
inflation valve caps. Without
the valve cap, dirt or moisture
could get into the valve core
and cause air leakage. If a
valve cap is missing, install a
new one as soon as possible.
CAUTION
Ty r e p r e s s u r e
Always observe the following:
•Check tyre pressure when the
tyres are cold, i.e. after the
vehicle has been parked for at
least three hours or hasn't
been driven more than 1.6 km
since startup.
•Check the pressure of your
spare tyre each time you
check the pressure of other
tyres.
•Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
•Wo r n , o l d t y r e s c a n c a u s e
accidents. If your tread is
badly worn, or if your tyres
have been damaged, replace
them.
CAUTION
Ty r e i n f l a t i o n
Overinflation or underinflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure. This
could result in loss of vehicle
control and potential injury.

2. Evaporative emission con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.
Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored in
the onboard canister. When the
engine is running, the fuel vapours
absorbed in the canister are drawn
into the surge tank through the purge
control solenoid valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control
system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
whilst maintaining good vehicle per-
for mance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
•If you use unauthorised electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorised
electronic devices.
