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 andcause 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 typediesel 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 exceeding7% with biodiesel will cause increased
wear or damage to the engine and fuel
system. Repair or replacement of worn ordamaged components due to the use of
non approved fuels will not be covered by
the manufactures warranty.CAUTION
 Do not let any gasoline or water enter the tank. This would make it
necessary to drain it out and to bleed the lines to avoid jammingthe injection pump and damagingthe engine.
 In winter, in order to cut down incidents due to freezing, paraffinoil may be added to the fuel if the temperature drops to below -10°C
(14°F). Never use more than 20% paraffin oil.
CAUTION - Diesel Fuel
(if equipped with DPF)
It is recommended to use the regu- lated automotive diesel fuel for
diesel vehicle equipped with theDPF system.
If you use diesel fuel including highsulfur (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.

Owner maintenance precautions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section, sev-
eral procedures can be done only by an
authorized HYUNDAI dealer with special
tools.
✽✽
NOTICE
Improper owner maintenance during the warranty period may affect warran-
ty coverage. For details, read the sepa-
rate Service Passport provided with the
vehicle. If you're unsure about any serv-
icing or maintenance procedure, have itdone by an authorized HYUNDAI deal-
er.
WARNING - Maintenance
work
 Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized HYUNDAI dealer.
 Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near theengine or cooling fans.WARNING - Diesel Engine
Never work on injection system with the engine running or within30 seconds after shutting off the
engine. High-pressure pump, rail,
injectors and high-pressure pipes
are subject to high pressure even
after the engine stopped. The fuel
jet produced by fuel leaks may
cause serious injury, if it touches
the body. People using pacemakers
should not move than 30cm closerto the ECU or wiring harness within
the engine room while engine is
running, since the high currents in
the electronic engine control sys-
tem produce considerable magnet-ic fields.

Maintenance
NORMAL MAINTENANCE SCHEDULE - EXCEPT EUROPE
The following maintenance services must be performed to ensure good emission control and performance. Keep receipts for all
vehicle emission services to protect your warranty. Where both mileage and time are shown, the frequency of service is deter-
mined by whichever occurs first. *1
: Adjust alternator and power steering (and water pump drive
belt) and air conditioner drive belt (if equipped).
Inspect and if necessary repair or replace.
* 2
: Check the engine oil level and leak every 500 km (350
miles) or before starting a long trip.
* 3
: Driving in summer season temperature over 40 °C (104 °F
- SAUDI, UAE, OMAN, KUWAIT, BAHRAIN, QATAR, IRAN,
YEMEN ETC) or driving over 170 km/h (106 mile/h) must
conform the severe driving condition.
* 4
: This maintenance schedule depends on fuel quality. It is
applicable only when using a qualified fuel <"EN590 or
equivalent">. If the diesel fuel specifications don't meet the
EN590, it must be replaced more frequently. HYUNDAI rec-
ommends "every 7,500km inspection, every 15,000kmreplacement".
If there are some important safety matters like fuel flow
restriction, surging, loss of power, hard starting problemetc., replace the fuel filter immediately regardless of main-
tenance schedule and consult an authorized HYUNDAI
dealer for details *
5
: For your convenience, it can be replaced prior to it's interval
when you do maintenance of other items.
* 6
: Inspect for excessive valve noise and/or engine vibration
and adjust if necessary. An authorized HYUNDAI dealer
should perform the operation.
* 7
: The fuel filter is considered to be maintenance free but peri-
odic inspection is recommended for this maintenance
schedule depends on fuel quality. If there are some impor-
tant matters like fuel flow restriction, surging, loss of power,
hard starting problem etc, replace the fuel filter immediate-ly regardless of maintenance schedule and consult an
authorized HYUNDAI dealer for details.
* 8
: When adding coolant, use only deionized water or soft
water for your vehicle and never mix hard water in the

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 fre-quent oil and filter changes are required. Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically forproper tension and adjusted as neces-
sary. Fuel filter (cartridge) A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. Fuel filters should be
installed by an authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.
WARNING -
Diesel only
Never work on the injection system with the engine running or within30 seconds after shutting off the
engine. High pressure pump, rail,
injectors and high pressure pipes
are subject to high pressure even
after the engine stops. The fuel jet
produced by fuel leaks may cause
serious injury, if it touches the
body. People using pacemakers
should not move more than 30cm
closer to the ECU or wiring harness
within the engine room while the
engine is running, since the highcurrents in the Common Rail sys-
tem produce considerable magnet-ic fields.

FUEL FILTER (FOR DIESEL)
Draining water from the fuel filter
The fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in itsbottom.
If water accumulates in the fuel filter, the
warning light comes on when the ignition
switch is in the ON position. If this warning light illuminates,
take your car to an authorized
HYUNDAI dealer and have
the water drained and
checked. Extracting air from the fuel filter
If you drove until you have no fuel left or
if you replaced the fuel filter, be sure to
extract air in the fuel system as it makes
you difficult to start the engine.
1. Remove the air extract nozzle cap on
the fuel filter.
2. Pump up and down until the fuel flows out of the plug opening.
