Introduction
Gasoline containing alcohol andmethanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded gasoline. Do not use gasohol containing more than 10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufactur-
er’s warranty if they result from the useof:
1. Gasohol containing more than 10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
Use of MTBE
HYUNDAI recommends avoiding fuels
containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
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 acci-dent.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to the catalytic converter and willdamage the engine control sys-
tem’s oxygen sensor and affectemission control.
Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Consult
an authorized HYUNDAI dealer for details.)
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuelsystem and any performance prob-lems that are caused by the use of
fuels containing methanol or fuels containing MTBE (Methyl TertiaryButyl Ether) over 15.0% vol. (Oxygen Content 2.7% weight.)
CAUTION
Never use gasohol which containsmethanol. Discontinue use of any gasohol product which impairs dri-
vability.

Fuel gauge
The fuel gauge indicates the approxi- mate amount of fuel remaining in the fueltank.
The fuel tank capacity is given in sec-
tion 8.The fuel gauge is supplemented by
a low fuel warning light, which will illumi-
nate when the fuel tank is near 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 thetank.
Trip computer
The trip computer is a microcomputer-
controlled driver information system that
displays information related to driving,
including odometer, tripmeter, elapsed
time, average speed, average fuel con-sumption (if equipped), instant fuel con-sumption (if equipped) and distance to
empty on the display when the ignition
switch is in the ON position. All stored
driving information (except odometer) is
reset if the battery is disconnected.

WARNING - Fuel gauge
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addition-
al fuel as soon as possible after thewarning light comes on or when the
gauge indicator comes close to the
E level.
CAUTION
Avoid driving with a very low fuel level. Running out of fuel, could cause the engine to misfire damag-ing the catalytic converter.

Features of your vehicle
Door open position indicator
This indicator illuminates when a door,
hood or trunk is not closed securely.
The indicator displays that which one is opened.
Immobilizer indicator
If any of the following occurs, the immo-
bilizer indicator illuminates, blinks or the
light goes off.
When the smart key is in the vehicle, ifthe engine start/stop button is turned
to the ACC or ON position, the indica-tor will illuminate until the engine is
started. However, when the smart key
is not in the vehicle, if the engine
start/stop button is pressed, the indica-
tor will blink for a few minutes to indi-
cate that you are not be able to start
the engine.
When the engine start/stop button is turned to the ON position from the
ACC position without the smart key in
the vehicle, the indicator blinks for a
few minutes to indicate that you are not
be able to start the engine.
When the battery is weak, if the engine start/stop button is pressed, the indica-
tor will blink and you are not be able to
start the engine. However, you are able
to start the engine by inserting the
smart key in the smart key holder. If
smart key system related parts have a
problem, the indicator will blink.
Low fuel level warning light
This warning light indicates the fuel tank
is nearly empty. When it comes on, you
should add fuel as soon as possible.
Driving with the fuel level warning light on
or with the fuel level below “E” can causethe engine to misfire and damage the
catalytic converter.
Low washer fluid level
warning light
This warning light indicates the washer
fluid reservoir is near empty. Refill the
washer fluid as soon as possible.

Maintenance

Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
When the vehicle is stopped in an open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
Never sit in a parked or stopped vehi- cle for any extended time with the
engine running.
When the engine stalls or fails to start, excessive attempts to restart the
engine may cause damage to theemission control system.Operating precautions for catalytic
converters (if equipped)
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL for gaso- line engines.
Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance. Do not misuse or abuse the engine.
Examples of misuse are coasting withthe ignition off and descending steep
grades in gear with the ignition off.
Do not operate the engine at high idle speed for extended periods (5 minutesor more).
Do not modify or tamper with any part of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorized
HYUNDAI dealer.
Avoid driving with a very low fuel level. If you run out of gasoline, it couldcause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautionscould result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.
WARNING - Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park, idle, or drive the
vehicle over or near flammable
objects, such as grass, vegetation,
paper, leaves, etc.
