Features of your vehicle
ECO GUIDE gauge
This is a gauge to let drivers know
whether the current driving condition is
economical or not. The fuel efficiency is
high in the blue zone but is low in the red
zone.
Fuel gauge
The fuel gauge indicates the approxi-
mate amount of fuel remaining in the fuel
tank.
The fuel tank capacity is given in
section 8.The fuel gauge is supplement-
ed by a low fuel warning light, which will
illuminate when the fuel tank is near
empty.
On inclines or curves, the fuel gauge
may fluctuate or the low fuel warning light
may come on earlier than usual due to
the movement of fuel in the tank.
OYFH041048NCAUTION
Avoid driving with a very low fuel
level. Running out of fuel could
cause the engine to misfire, damag-
ing the catalytic converter.
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.

Features of your vehicle
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 cause
the engine to misfire and damage the
catalytic converter.
Engine coolant
temperature warning light
(if equipped)
The warning light illuminates if the tem-
perature of the engine coolant is above
257±4.5°F (125±2.5°C).
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “Overheating” in section 6.
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 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
engine start/stop button is turned to the
ON position, and will go out in a few sec-
onds after the engine is started. If it illu-
minates while driving, or does not illumi-
nate when the engine start/stop button is
turned to the ON position, take your vehi-
cle to your nearest 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.
CAUTION
Prolonged driving with the
Malfunction Indicator Light illumi-
nated may cause damage to the
emission control systems which
could effect drivability and/or fuel
economy.

If the Malfunction Indicator Light
illuminates, potential catalytic
converter damage is possible.
This could result in loss of engine
power. Have the Engine Control
System inspected as soon as pos-
sible by an authorized HYUNDAI
dealer.

What to do in an emergency
2. When the vehicle is stopped, turn on
your emergency hazard flashers, set
the parking brake and put the transaxle
in P (automatic transaxle).
3. Have all passengers get out of the car.
Be sure they all get out on the side of
the car that is away from traffic.
4. When changing a flat tire, follow the
instruction provided later in this sec-
tion.
If vehicle 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 get vehicle moving in drive
again. If your vehicle will not more,
contact an authorized HYUNDAI deal-
er or seek other qualified assistance.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. 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 engine start/stop button in
the LOCK position, check all connec-
tors at ignition coils and spark plugs.
Reconnect any that may be discon-
nected or loose.
3. If the engine still does not start, call an
authorized HYUNDAI dealer or seek
other qualified assistance.
IF THE VEHICLE WILL NOT START
WARNING
If the vehicle will not more, 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
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 minutes
or 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 precautions
could 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.
