HOW TO USE THIS MANUAL
WARNING
A WARNING indicates a situation in
which harm, serious bodily injury ordeath could result if the warning isignored.
CAUTION
A CAUTION indicates a situation in which damage to your vehicle couldresult if the caution is ignored.
FUEL REQUIREMENTS
CAUTION
NEVER USE LEADED FUEL. Theuse of leaded fuel is detrimental tothe catalytic converter and will damage the engine control sys-

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.
WARNING
Never remove the radiator cap
when the engine is hot. The enginecoolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.

When the ignition switch is turned to
the ON position and the indicator turns
off after 2 seconds, the system may
have a problem. Have the vehicle
checked by an authorised HYUNDAI
dealer.
When the battery is weak, if the engine start/stop button is depressed, the indi-
cator will blink and you will not be able
to start the engine. However, you may
still be 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
blinks.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.
Malfunction indicator light
(MIL) (check engine light)
This indicator light is part of the Engine
Control System which monitors various
emission control system components. If
this light illuminates whilst driving, it indi-cates that a potential malfunction has
been detected somewhere in the emis-sion control system. This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
whilst driving, or does not illuminate
when the ignition switch is turned to the
ON position, take your vehicle to your
nearest authorised HYUNDAI dealer and
have the system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorised HYUNDAI dealer promptly.

IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatic
transaxle, be sure the shift lever is in N
(Neutral) or P (Park) and the emer-
gency brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you operate the
starter, the battery is discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump starting". If engine turns over normally but
does not start
1. Check fuel level.
2. With the ignition switch in the LOCK
/OFF position, check all connectors at
the ignition coils and spark plugs.
Reconnect any that may be discon-
nected or loose.
3. If the engine still does not start, call an authorised HYUNDAI dealer or seek
other qualified assistance.
WARNING
If the engine will not start, do not
push or pull the vehicle to start it.This could result in a collision or
cause other damage. In addition,
push or pull starting may cause the
catalytic converter to be over-
loaded and create a fire hazard.

Maintenance

7
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:
Make sure to refuel your vehicle according to the "Fuel requirements" suggested in section 1.
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 authorised
HYUNDAI dealer.
Avoid driving with a extremly low fuel level. Running out of fuel could cause
the engine to misfire, damaging 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, vegeta-
tion, paper, leaves, etc.
The exhaust system and catalytic system are very hot while the
engine is running or immediately
after the engine is turned off. Keep
away from the exhaust system
and catalytic, you may get burned.
Also, do not remove the heat sink
around the exhaust system, do
not seal the bottom of the vehicle
or do not coat the vehicle for cor-
rosion control. It may present a
fire risk under certain conditions.
