Introduction
Diesel engine
Diesel fuel
Diesel engine must be operated only on
commercially available diesel fuel that
complies with EN 590 or comparable
standard. (EN stands for "European
Norm"). Do not use marine diesel fuel,
heating oils, or non-approved fuel addi-
tives, as this will increase wear and
cause damage to the engine and fuel
system. The use of non-approved fuels
and / or fuel additives will result in a limi-
tation 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 tem-
perature 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 care-
fully : If the engine stops through fuel fail-
ure, the circuits must be completely
purged to permit restarting.
Biodiesel
Commercially supplied Diesel blends of
no more than 7% biodiesel, commonly
known as "B7 Diesel" may be used in
your vehicle if Biodiesel meets EN 14214
or equivalent specifications. (EN stands
for "European Norm"). The use of biofu-
els exceeding 7% made from rapeseed
methyl ester (RME), fatty acid methyl
ester (FAME), vegetable oil methyl ester
(VME) etc. or mixing diesel exceeding
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 manufacturers warranty.CAUTION
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.
CAUTION- Diesel Fuel
It is recommended to use the regu-
lated automotive diesel fuel for
diesel vehicle equipped with the
DPF system.
If you use diesel fuel including high
sulfur (more than 50 ppm sulfur)
and unspecified additives, it can
cause the DPF system to be dam-
aged and white smoke can be emit-
ted.
CAUTION
• Never use any fuel, whether
diesel, B7 biodiesel or otherwise,
that fails to meet the latest petro-
leum industry specification.
• Never use any fuel additives or
treatments that are not recom-
mended or approved by the vehi-
cle manufacturer.

Features of your vehicle
Engine coolant tempera-
ture warning light
(if equipped)
The warning light illuminates if the tem-
perature of the engine coolant is above
125±2.5°C (257±4.5°F).
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “Overheating” in section 6.
✽NOTICE
If the engine coolant temperature warn-
ing light illuminates, it indicates over-
heating that may damage the engine.
ESC (Electronic Stability
Control) indicator
(if equipped)
The ESC indicator will illuminate when
the ignition switch is turned ON, but
should go off after approximately 3 sec-
onds. When the ESC is on, it monitors
the driving conditions. Under normal driv-
ing conditions, the ESC indicator will
remain off. When a slippery or low trac-
tion condition is encountered, the ESC
will operate, and the ESC indicator will
blink to indicate the ESC is operating.
But, if the ESC system malfunctions the
indicator illuminates and stays on. Take
your vehicle to an authorised HYUNDAI
dealer and have the system checked.
CAUTION - Diesel engine
If the Emission Control System
Malfunction Indicator Light blinks,
some error related to the injection
quantity adjustment occurs which
could result in loss of engine
power, combustion noise and poor
emission. Have the Engine Control
System inspected as soon as pos-
sible by an authorised HYUNDAI
dealer.

Features of your vehicle
Glow indicator
(Diesel engine)
The indicator light illuminates when the
ignition switch is placed at the ON posi-
tion. The engine can be started after the
preheat indicator light goes off. The illu-
minating time varies with the water tem-
perature, air temperature and battery
condition.
✽NOTICE
If the engine was not started within 10
seconds after the preheating is complet-
ed, turn the ignition key once more to
the LOCK position during 10 seconds,
and then to the ON position, in order to
preheat again.
Fuel filter warning light
(Diesel engine)
This warning light illuminates for 3 sec-
onds after the ignition switch is set to the
ON position and then it will go out. If it
lights up whilst the engine is running, it
indicates that water has accumulated
inside the fuel filter. If this happens,
remove the water from the fuel filter. For
more Information, refer to “Fuel filter” in
section 7.
Electric power steering
(EPS) system warning light
This indicator light comes on after the
ignition key is turned to the ON position
and then it will go out.
This light also comes on when the EPS
has some troubles. If it comes on whilst
driving, have your vehicle inspected by
an authorised HYUNDAI dealer.
CAUTION
If the preheat indicator light contin-
ues to illuminate or flash on and off
after the engine has warmed up or
whilst driving, check the system by
an authorised HYUNDAI dealer as
soon as possible.
CAUTION
When the fuel filter warning light is
illuminated, engine power (vehicle
speed & idle speed) may decrease.
If you keep driving with the warning
light on, you can damage your vehi-
cle's engine parts and injection sys-
tem of the Common Rail. If this
occurs, have your vehicle checked
by an authorised HYUNDAI dealer
as soon as possible.

• To keep dust or unpleasant fumes from
entering the vehicle through the venti-
lation system, temporarily set the air
intake control to the recirculated air
position. Be sure to return the control
to the fresh air position when the irrita-
tion has passed to keep fresh air in the
vehicle. This will help keep the driver
alert and comfortable.
• Air for the heating/cooling system is
drawn in through the grilles just ahead
of the windscreen. Care should be
taken that these are not blocked by
leaves, snow, ice or other obstructions.
• To prevent interior fog on the wind-
screen, set the air intake control to the
fresh air position and fan speed to the
desired position, turn on the air condi-
tioning system, and adjust the temper-
ature control to desired temperature.

✽NOTICE
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely whilst driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in humid
weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be used
with the windows closed.
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.
• To help reduce moisture inside of the
windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
• During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
• Use the air conditioning system every
month only for a few minutes to ensure
maximum system performance.• When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
• Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
• During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristic.
• If you operate air conditioner exces-
sively, the difference between the tem-
perature of the outside air and that of
the windscreen could cause the outer
surface of the windscreen to fog up,
causing loss of visibility. In this case,
set the mode selection knob or button
to the position and fan speed con-
trol to the lower speed.

Features of your vehicle
Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windscreen even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorised HYUNDAI
dealer.
✽NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty or rough
roads, more frequent air conditioner
filter inspections and changes are
required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorised HYUNDAI
dealer.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
impact on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorised HYUNDAI dealer.
✽NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur.
WARNING
The air conditioning system should
be serviced by an authorised
HYUNDAI dealer. Improper service
may cause serious injury to the
person performing the service.
