Diesel 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 typediesel 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.
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.

Introduction
Do not let any petrol or water
enter the tank. This would make
it necessary to drain it out and
to bleed the lines to avoid jam-
ming the injection pump and
damaging the engine.
CAUTION
Diesel Fuel
(if equipped with DPF)
It is recommended to use the
regulated 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 addi-
tives, it can cause the DPF sys-
tem to be damaged and white
smoke can be emitted.

Convenient features of your vehicle
• When the Fuel Filter Warning Light illuminates, engine power
(vehicle speed & idle speed) may
decrease.
• If you keep driving with the warn- ing light on, engine parts (injec-
tor, common rail, high pressure
fuel pump) may be damaged. If
this occurs, we recommend that
you have the vehicle inspected
by a HYUNDAI authorised repair-
er as soon as possible.
4 Wheel Drive (4WD)Warning Light (if equipped)
This warning light illuminates:
• Once you set the ignition switch or
Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds and then goes off.
• When there is a malfunction with the 4WD system.
In this case, we recommend that
you have the vehicle inspected by
a HYUNDAI authorised repairer.
Headlight WarningLight (if equipped)
This warning light illuminates:
• When there is a malfunction
(burned- out bulb except LED light
or circuit malfunction) with the
exterior lights (headlight, brake
light, fog light, etc.). In this case,
we recommend that you have your
vehicle inspected by a HYUNDAI
authorised repairer.
Information
Make sure to replace the burned out
bulb with a new one of the same
wattage rating.
If not, this warning message will not
be displayed.

Maintenance
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in the enginecoolant reservoir.
• Check the windscreen washer fluid level.
• Check for low or under-inflated tyres.
Whilst operating your vehicle:
• Note any changes in the sound of the exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
• Notice if your vehicle constantly turns slightly or “pulls” to one side when
travelling on smooth, level road.
• When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
• If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
• Check the automatic transaxle/ dual clutch transmission P (Park)
function.
• Check the parking brake.
• Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pres-
sure pump, high-pressure
pipes, rail, and injectors are still
subject to the high pressure
right after stopping the diesel
engine.
When the fuel leakage vents
out, it may cause serious body
injury. Any people, who are
implemented with the artificial
cardiac pacemaker, should
remain away from the ECU or
the wiring harness by at least 30
cm, whilst running the diesel
engine. The high currents of the
electric engine control system
produce a considerable amount
of magnetic fields.

Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (cartridge)
A clogged-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the
hard starting. When a considerable
amount of foreign substances are
accumulated in the fuel tank, the fuel
filter should be replaced.
Upon installing a new fuel filter, oper-
ate the diesel engine for several min-
utes, and check the connections for
any leakages. We recommend you to
have the fuel filter replaced by a
HYUNDAI authorised repairer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by a HYUNDAI authorised
repairer.
When you are inspecting the belt,
place the ignition switch to the
LOCK/OFF or ACC position.
CAUTION
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
the high pressure right after
stopping the diesel engine. When
the fuel leakage vents out, it may
cause serious body injury. Any
people, who are implemented
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm whilst running the
diesel engine. The high currents
of the common rail system pro-
duce a considerable amount of
magnetic fields.
