Convenient features of your vehicle
Fuel filler door
Opening the fuel filler door
1. Turn the engine off.
2. Push the center edge of the fuelfiller door when the driver’s door is
unlocked. 3. Pull the fuel filler door (1) out to
fully open.
4. To remove the fuel tank cap (2), turn it counterclockwise. You may
hear a hissing noise as the pres-
sure inside the tank equalizes.
5. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.

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 inchapter 8.
• The fuel gauge is supplemented 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 a 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
when the engine is hot. The
engine coolant is under pressure
and could severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.
WARNING
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "0" level.

What to do in an emergency
6
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soonas it is safe to do so.
2. Place the shift lever in P (Park, for automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission/dual clutch
transmission vehicle) and set the
parking brake. If the air condition-
ing is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running
or the steaming has stopped. If
there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off. 4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had been
in use, it is normal for cold water to
be draining from it when you stop.)
5. If engine coolant is leaking out, stop the engine immediately and we rec-
ommend that you call an authorized
HYUNDAI dealer for assistance.

While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the
radiator cap or the
drain plug while the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

Maintenance
Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorized
HYUNDAI dealer.
Spark plugs
(for Gasoline Engine)
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(for Gasoline Engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by an authorized HYUNDAI
dealer.
Cooling system
Check the cooling system parts,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transmission fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid changed by an
authorized HYUNDAI dealer accord-
ing to the maintenance schedule.
Information
Automatic transmission fluid color is
basically red.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.
The use of a non-specified fluid
could result in transmission mal-
function and failure.
Use only specified automatic
transmission fluid.
(Refer to “Recommended lubri-
cants and capacities” in chapter 8.)
Manual transmission fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
NOTICE
