DDiesel engine
Diesel fuel
Diesel engine must be operated only
on commercially available diesel fuel
that complies with EN 590 or compa-
rable standard. (EN stands for
"European Norm"). Do not use
marine diesel fuel, heating oils, or
non-approved fuel additives, as this
will increase wear and cause dam-
age to the engine and fuel system.
The use of non-approved fuels and /
or fuel additives will result in a limita-
tion of your warranty rights.
Diesel fuel of above cetane 51 is
used in your vehicle. If two types of
diesel fuel are available, use summer
or winter fuel properly according to
the following temperature conditions.
• Above -5°C (23°F) ... Summer type
diesel fuel.
• Below -5°C (23°F) ... Winter type diesel fuel.
Watch the fuel level in the tank very
carefully : If the engine stops through
fuel failure, the circuits must be com-
pletely purged to permit restarting.Do not let any petrol or water enter
the tank. This would make it neces-
sary to drain it out and to bleed the
lines to avoid jamming the injection
pump and damaging the engine.
- Diesel Fuel (if equipped with DPF)
It is recommended to use the regu-
lated automotive diesel fuel for diesel
vehicle equipped with the DPF sys-
tem.
If you use diesel fuel including high
sulfur (more than 50 ppm sulfur) and
unspecified additives, it can cause
the DPF system to be damaged and
white smoke can be emitted.
Biodiesel
Commercially supplied Diesel blends
of no more than 7% biodiesel, com-
monly known as "B7 Diesel" may be
used in your vehicle if Biodiesel
meets EN 14214 or equivalent spec-
ifications. (EN stands for "European
Norm"). The use of biofuels exceed-
ing 7% made from rapeseed methyl
ester (RME), fatty acid methyl ester
(FAME), vegetable oil methyl ester
(VME) etc. or mixing diesel exceed-
ing 7% with biodiesel will cause
increased wear or damage to the
engine and fuel system. Repair or
replacement of worn or damaged
components due to the use of non
approved fuels will not be covered by
the manufactures warranty.
• Never use any fuel, whether diesel, B7 biodiesel or otherwise,
that fails to meet the latest petrole-
um industry specification.
• Never use any fuel additives or treatments that are not recom-
mended or approved by the vehi-
cle manufacturer.

IIf the gauge pointer moves beyond
the normal range area toward the “H”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “If the Engine
Overheats” in chapter 6.
Fuel GaugeThis gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
The fuel tank capacity is given in chapter 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.i
NOTICENever 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.

Operation Tips• To keep dust or unpleasant fumes from entering the car through the
ventilation system, temporarily set
the air intake control to the recircu-
lated air position. Return the con-
trol to the fresh air position when
the irritation has passed. This will
help keep the driver alert and com-
fortable.
• To prevent inside of the windshield from fogging, set the air intake con-
trol to the fresh air position and fan
speed to the desired position, turn
on the air conditioning system, and
adjust the temperature control to
desired temperature.
Air conditioning (if equipped) HYUNDAI Air Conditioning Systems
are filled with a R-134a refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Level mode.
4. Set the air intake control to the recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
lowest setting (LO) then set the fan
speed control to the highest speed.

WWhen using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine
overheating. Continue to use the
blower fan but turn the air condition-
ing system off if the engine tempera-
ture gauge indicates engine over-
heating.
Air conditioning system operation
tips • If the vehicle has been parked in direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
• After sufficient cooling has been achieved, switch back from the
recirculated air to the fresh outside
air position.
• To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the win-
dows closed.
• Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance. • If you operate air conditioner
excessively, the difference between
the temperature of the outside air
and that of the windshield could
cause the outer surface of the
windshield to fog up, causing loss
of visibility. In this case, set the
mode selection knob or button to
the position and fan speed
control to the lower speed.

)' #10*30-30.2+3%.,/3(21+2"1,/2*3!-$&3SSystem maintenanceClimate control air filter This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
We recommend the climate control
air filter be cleaned according to the
maintenance schedule. If the car is
being driven in severe conditions such as dusty or rough roads, more
frequent air conditioner filter inspec-
tions and cleaning are required. If the air flow rate suddenly decreas-
es, we recommend the system be
checked at an authorized HYUNDAI
dealer.
Checking the amount of air
conditioner refrigerant and com- pressor lubricantWhen the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the system
be inspected by an authorized
HYUNDAI dealer.
Information
It is important that the correct type
and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur.i

Starting the diesel engine
To start the diesel engine when the
engine is cold\b it has to be preheat
ed before starting the engine and
then have to be warmed up before
starting to drive.
Vehicle with manual transaxle:
1.Make sure the parking brake isapplied.
2.Make sure the shift lever is in neu tral.
3.Depress the clutch and brake ped als.
4.Turn the ignition switch to the ON position to preheat the engine.
The glow indicator light ( ) will
illuminate.
5.When the glow indicator light ( ) goes out\b turn the key ignition
switch to the START position. Hold
the key (maximum of 1\f seconds)
until the engine starts and release
it. Information
If the engine does not start within 10
seconds after preheating is completed,
turn the ignition switch once more to
the LOCK position and wait for 10
seconds\b Then turn the ignition switch
to the ON position in order to preheat
the engine again\b
Starting and stopping the engine
for turbocharger intercooler
1.Do not race or accelerate the engine immediately after starting
the engine.
If the engine is cold\b idle for sever
al seconds before sufficient lubri
cation is ensured in the turbo
charger unit.
2.After high speed or extended driv ing that requires heavy engine
load\b idle the engine about one
minute before turning the engine
off.
This idle time will allow the tur
bocharger to cool prior to shutting
the engine off.
Do not turn off the engine immedi
ately after it has been subjected to a
heavy load. Doing so may cause
severe damage to the engine or
turbo charger unit.
