Opening the fuel filler lid
The fuel filler lid must be opened from
inside the vehicle by pressing the fuel
filler lid open button located on the dri-
ver’s door.
✽NOTICE
If the fuel filler lid does not open
because ice has formed around it, tap
lightly or push on the lid to break the ice
and release the lid. Do not pry on the lid.
If necessary, spray around the lid 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.
1. Stop the engine.
2. Push the fuel filler lid opener button,
then the fuel filler lid slowly open (1).
3. To remove the cap, turn the fuel tank
cap (2) counterclockwise.
4. Refuel as needed.
Closing the fuel filler lid
1. To install the cap, turn it clockwise until
it “clicks”. This indicates that the cap is
securely tightened.
2. Close the fuel filler lid and push it light-
ly and make sure that it is securely
closed.

WARNING - Refueling
• If pressurized fuel sprays out, it
can cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
• 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.

Fuel gauge
The fuel gauge indicates the approxi-
mate amount of fuel remaining in the fuel
tank.
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.
WARNING
Never remove the radiator cap
when the engine is hot. The engine
coolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.
OVI049055
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 very low fuel
level. Running out of fuel, could
cause the engine to misfire damag-
ing the catalytic converter.

What to do in an emergency
6 6
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in P and set the
parking brake. If the air conditioning is
on, turn it off.
3. If engine coolant is running out under
the vehicle or steam is coming 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 operat-
ing. If the fan is not running, turn the
engine off.4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop).
5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If over-
heating happens again, call an author-
ized HYUNDAI dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized
HYUNDAI dealer.

Air cleaner filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (3.8L)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Automatic transmission fluid
Automatic transmission fluid should not
be checked under normal usage condi-
tions.
But in severe conditions, the fluid should
be changed at an authorized HYUNDAI
dealer in accordance to the scheduled
maintenance at the beginning of this
chapter.
✽NOTICE
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.
CAUTION
The use of a non-specified fluid
could result in transmission mal-
function and failure.
Use only specified automatic trans-
mission fluid. (Refer to
“Recommended lubricants and
capacities” in section 8.)
