which, if not avoided, could result
in vehicle damage.

obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.
NOTICE
•Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
•Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WA R N I N G
NEVER USE LEADED FUEL.
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.
CAUTION
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.

Introduction
Petrol containing ethanol
Ethanol [E-10], a mixture of petrol
and ethanol (also known as grain
alcohol), is marketed along with or
instead of leaded or unleaded petrol.
Do not use petrol containing more
than 10% ethanol, and do not use
petrol or ethanol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using ethanol of any
kind if driveability problems occur.
Ve h i c l e d a m a g e o r d r i v e a b i l i t y p r o b -
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Petrol containing more than 10%
ethanol.
2. Petrol or ethanol containing
methanol.
3. Leaded fuel or leaded ethanol.
Other fuels
Using fuel additives such as:
-Silicone fuel additive
-MMT (Magnanese, Mn) fuel additive
-Ferrocene (iron-based) fuel additive
-Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, dam-
age to the catalytic converter, or
abnormal corrosion, and may cause
damage to the engine resulting in a
reduction in the overall life of the
powertrain.
Damage to the fuel system or per-
formance problems caused by the
use of these fuels, may not be cov-
ered by your New Vehicle Limited
Warranty.
NOTICE
Never use fuel which contains
methanol. Discontinue use of
any petrol containing ethanol
which impairs drivability.

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 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.

Convenient features of your vehicle
Low Fuel Level
Warning Light
This warning light illuminates:
•When the fuel tank is nearly empty.
Add fuel as soon as possible.
Driving with the Low Fuel Level
warning light on or with the fuel
level below "E" can cause the
engine to misfire and damage the
catalytic converter (if equipped).
Washer Fluid Warning
Light (if equipped)
This warning light illuminates:
•When the washer fluid level in the
reservoir is nearly empty.
In this case, you should refill the
washer fluid.
Overspeed Warning
Light (if equipped)
This warning light blinks:
•When you drive the vehicle over
120 km/h.
- This is to warn you that you are
exceeding 120 km/h.
- The overspeed warning chime
also sounds for approximately 5
seconds.

Maintenance
Operating precautions for
catalytic converters
(if equipped)
Yo u r v e h i c l e i s e q u i p p e d w i t h a c a t -
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Failure to obser ve these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
(Continued)
•Do not operate the engine at
high idle speed for extended
periods (5 minutes or more).
•Do not modify or tamper with
any part of the engine or
emission control system. All
inspections and adjustments
must be made by an autho-
rised HYUNDAI dealer.
•Avoid driving with a very low
fuel level. If you run out of
petrol, it could cause the
engine to misfire and result in
excessive loading of the cat-
alytic converter.
•Use only UNLEADED FUEL
for petrol engines.
•Do not operate the vehicle
when there are signs of
engine malfunction, such as
misfire or a noticeable loss of
performance.
•Do not misuse or abuse the
engine. Examples of misuse
are coasting with the engine
off and descending steep
grades in gear with the engine
off.
(Continued)
CAUTION•A hot exhaust system can
ignite flammable items under
your vehicle. Do not park,
idle, or drive the vehicle over
or near flammable objects,
such as dry grass, paper,
leaves, etc.
•The exhaust system and cat-
alytic system are very hot
whilst the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic converter as you may
get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle and do not coat
the vehicle for corrosion con-
trol. It may present a fire risk
under certain conditions.
