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 the tank. The bottom segment will flash as the fuel
level approaching empty.
Trip computer
The trip computer is a microcomputer-
controlled driver information system that
displays information related to driving,
including odometer, tripmeter, distance
to empty, average fuel consumption,
average speed, driving time on the dis-
play when the ignition switch is in the ON
position. All stored driving information
(except odometer and distance to empty)
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 the warning light comes on or when the
gauge indicator comes close to the
E level.
CAUTION
Avoid driving with a extremely low
fuel level. Running out of fuel couldcause the engine to misfire, damag- ing the catalytic converter.

Charging system warning
light
This warning light indicates a malfunction
of either the generator or electricalcharging system.
If the warning light comes on while the
vehicle is in motion:
1. Drive to the nearest safe location.
2. With the engine off, check the genera- tor drive belt for looseness or break-
age.
3. If the belt is adjusted properly, a prob- lem exists somewhere in the electrical
charging system. Have an authorized
HYUNDAI dealer correct the problem
as soon as possible.
Door ajar warning light
This warning light illuminates when a door is not closed securely with the igni-
tion switch in any position.
Tailgate open warning light
This warning light illuminates when the tailgate is not closed securely with the
ignition switch in any position.
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 (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 while 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
while driving, or does not illuminate when
the ignition switch is turned to the ON
position, take your vehicle to your near-
est authorized HYUNDAI dealer and
have the system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorized HYUNDAI dealer promptly.

Features of your vehicle
ESC indicator (ElectronicStability Control)
(if equipped)
The ESC indicator will illuminate when
the ignition switch is turned ON, but
should go off after approximately 3 sec-
onds. When the ESC is on, it monitors
the driving conditions and under normal
driving conditions, the ESC indicator will
remain off. When a slippery or low trac- tion condition is encountered, the ESC
will operate, and the ESC indicator will
blink to indicate the ESC is operating. If the ESC system malfunctions the indica-
tor illuminates and stays on. Take your
vehicle to an authorized HYUNDAI deal-
er and have the system checked.
ESC OFF indicator (if equipped)
The ESC OFF indicator will illuminate
when the ignition switch is turned ON,
but should go off after approximately 3
seconds. To switch to ESC function off,
press the ESC OFF button. The ESCOFF indicator will illuminate indicating
the ESC is deactivated.
DBC (Downhill brake con-
trol) indicator (if equipped)
The DBC indicator will illuminate when
the DBC button is pressed and the sys-tem is on.
When driving down a steep hill at a speed under 22 mph (35 km/h), the DBC
will operate and the DBC indicator will
blink to indicate the DBC is operating.
If the red indicator illuminates, the DBC
system may have malfunctioned. Take
your vehicle to an authorized HYUNDAI
dealer and have the system checked.
CAUTION
Prolonged driving with the
Emission Control SystemMalfunction Indicator Light illumi-
nated may cause damage to theemission control systems whichcould effect drivability and/or fueleconomy.

If the EmissionControl System
Malfunction Indicator Light illumi- nates, potential catalytic converterdamage is possible which couldresult in loss of engine power.
Have the Engine Control Systeminspected as soon as possible byan authorized HYUNDAI dealer.

What to do in an emergency
2. When the vehicle is stopped, turn onyour emergency hazard flashers, set
the parking brake and put the transaxle
in P (automatic transaxle) or reverse
(manual transaxle).
3. Have all passengers get out of the vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
4. When changing a flat tire, follow the instruction provided later in this sec- tion.
If engine stalls while driving
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle will not start, contact an
authorized HYUNDAI dealer or seek
other qualified assistance.
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

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 the emission 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 with the 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 extremely 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.
