N OTICE indicates a situation which,
if not avoided, could result in vehicle
damage.
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.
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded petrol.
When you are going to use leaded
petrol, we recommend that you ask
an authorized HYUNDAI dealer
whether leaded petrol in your vehicle
is available or not.
Octane Rating of leaded petrol is
same with unleaded one.
NOTICE
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system clean-
ing agents to the fuel tank other
than what has been specified (We
recommend that you consult an
authorized HYUNDAI dealer for
details.)

Before touching the fuel nozzle,
you should eliminate the poten-
tial 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 cel-
lular 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 build-up of
static electricity by touching, rub-
bing or sliding against any item or
fabric capable of producing static
electricity. Static electricity dis-
charge can ignite fuel vapors
causing a fire.
(Continued)
(Continued)If you must re-enter the vehicle,
you should once again eliminate
potentially dangerous static elec-
tricity 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 vehicleshould be maintained until the
filling is complete.

IInformation
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the foreword chapter.
Do not spill fuel on the exterior sur- faces of the vehicle. Any type of fuel
spilled on painted surfaces may
damage the paint.If the fuel filler cap requires replace-
ment, 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.NOTICEi
(Continued)•
When refueling, always move
the shift lever to the P (Park)
position (for Continuously
Variable Transaxle vehicle) or
first gear or R (Reverse) position
(for Manual Transaxle vehicle),
set the parking brake, and place
the ignition switch to the
LOCK/OFF position. Sparks
produced by electrical compo-
nents 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.
(Continued)
(Continued)•
If a fire breaks out during refuel-
ing, leave the vicinity of the vehi-
cle, 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 remov-
ing the cap.
•
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.

IIf the gauge pointer moves beyond
the normal range area toward the “H”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “If the Engine
Overheats” in chapter 6.
Fuel GaugeThis gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
The fuel tank capacity is given in chapter 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.i
NOTICENever remove the radiator 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.

VVapor hose and fuel filler capThe 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.
Air cleaner filterWe recommend that the air cleaner
filter be replaced by an authorized
HYUNDAI dealer.Spark plugsMake sure to install new spark plugs
of the correct heat range.Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

•• Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformatio n also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, we recommend that the
system be checked by an author-
ized HYUNDAI dealer.
• Overinflation produces a harsh ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from roa d haz-
ards. • Warm tires normally exceed rec-
ommended cold tire pressures by
28 to 41 kPa (4 to 6 psi). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
• Be sure to reinstall the tire inflation
valve caps. Without the valve cap,
dirt or moisture could get into the
val ve core and cause air leakage.
If a valve cap is missing, install a
new one as soon as possible. - Tire
pressure
Always observe the following:
• Check tire pressure when the tires are cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than 1.6
km (one mile) since startup.)
• C heck the pressure of your spare
tire each time you check the pres-
sure of other tires.
• Never overload your vehicle. Be
careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
• Worn, old tires can cause acci-
dents. If your tread is badly worn,
or if your tires have been dam-
aged , replace them.

Tire Inflation
Overinflation or underinflation can
reduce tire life, adversely affect
vehicle handling, and lead to sud-
den tire failure. This could result in
loss of vehicle control and poten-
tial injury.

$$!!"#"#$The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
emission regulations.
There are three emission control
systems which are as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
car inspected and maintained by an
authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.
1. Crankcase emission control systemThe positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative emission controlsystemThe Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.CanisterFuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid 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.
