Opening the fuel filler door
1. Turn the engine off.
2. Push the fuel filler door opener
button.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 equalises.
Place the cap on the fuel filler door.
✽NOTICE
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.
Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “clicks” one time.
2. Close the fuel filler door until it is
latched securely.

Petrol is highly flammable and
explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
•Read and follow all warnings
posted at the petrol station.
•Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the petrol station.
•Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other petrol
source, with your bare hand.

Tachometer
The tachometer indicates the
approximate number of engine revo-
lutions per minute (rpm).
Use the tachometer to select the cor-
rect shift points and to prevent lug-
ging and/or over-revving the engine.
Engine Coolant Temperature
Gauge
This gauge indicates the tempera-
ture of the engine coolant when the
Engine Start/Stop button is in the ON
position. Do not operate the engine with-
in the tachometer's RED ZONE.
This may cause severe engine
damage.
CAUTION

■Type A
■Type B
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
If the gauge pointer moves
beyond the normal range area
toward the "130 or H" position,
it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your vehi-
cle overheats, refer to "If the
Engine Overheats" in chapter 6.
CAUTION

What to do in an emergency
6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call a
HYUNDAI authorised repairer for
assistance.
•Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by a
HYUNDAI authorised repairer.
•When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
CAUTION
NEVER remove the
radiator cap or the
drain plug whilst 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 whilst 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.

ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant concentration level at least
once a year, at the beginning of the
winter season, and before travelling
to a colder climate.Checking the coolant level
Removing radiator
cap
•
Never attempt to remove the
radiator cap whilst the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hot
coolant or steam.
•Turn the engine off and wait
until it cools down. Use
extreme care when removing
the radiator cap. Wrap a thick
towel around it, and turn it
counterclockwise slowly to
the first stop. Step back whilst
the pressure is released from
the cooling system.

WARNING
(Continued)
When you are sure all the
pressure has been released,
press down on the cap, using
a thick towel, and continue
turning counterclockwise to
remove it.
•Even if the engine is not oper-
ating, do not remove the radi-
ator cap or the drain plug
whilst the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.
•When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
•Do not drive with no engine
coolant. It may cause water
pump failure and engine
seizure, etc.
CAUTION

Radiator cap
Do not remove the
radiator cap when the
engine and radiator
are hot. Scalding hot
coolant and steam
may blow out under
pressure causing seri-
ous injury.
WARNING
Coolant
•
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
•Radiator coolant can severely
obscure visibility when
sprayed on the windscreen
and may cause loss of vehicle
control or damage to the paint
and body trim.
WARNING
Put a thick cloth or fabric
around the radiator cap before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as the generator.
