Introduction
Fuel Additives
HYUNDAI recommends that you use unleaded gasoline which has an octane
rating of RON (Research Octane
Number) 95 / AKI (Anti Knock Index) 91
or higher (for Europe) or Octane Rating
of RON (Research Octane Number) 91 /
AKI (Anti-Knock Index) 87 or higher
(except Europe).
For customers who do not use good
quality gasolines including fuel additives
regularly, and have problems starting or
the engine does not run smoothly, one
bottle of additives added to the fuel tank
at every 15,000km (for Europe)/ 5,000km
(except Europe). Additives are available
from your authorized HYUNDAI dealer
along with information on how to use
them. Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg-istration and insurance.
Determine that acceptable fuel is avail- able. 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 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.
CAUTION
Do not let any gasoline or water enter the tank. This would make itnecessary to drain it out and to
bleed the lines to avoid jamming the injection pump and damaging theengine.
CAUTION - Diesel Fuel
(if equipped with DPF)
It is recommended to use the regu- lated automotive diesel fuel fordiesel vehicle equipped with the DPF system.
If you use diesel fuel including highsulfur (more than 50 ppm sulfur)
and unspecified additives, it cancause the DPF system to be dam- aged and white smoke can be emit-
ted.

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, we recommend that the
system be serviced by an author-
ized 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.CAUTION
Do not put heavy objects or apply excessive force on top of theengine cover (if equipped) or fuel
related parts.
When you inspect the fuel system (fuel lines and fuel injection
devices), we recommend that youcontact an authorized HYUNDAI
dealer.
Do not drive long time with the engine cover (if equipped)
removed.
When checking the engine room, do not go near fire.
Fuel, washer fluid, etc. are flam-mable oils that may cause fire.
Before touching the battery, igni- tion cables and electrical wiring,
you should disconnect the bat- tery "-" terminal. You may get an
electric shock from the electriccurrent.
When you remove the interior trim cover with a flat head (-) driv-er, be careful not to damage the
cover.
Be careful when you replace and clean bulbs to avoid burns or
electrical shock.

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. ❈Inspect : Inspect and if necessary, adjust, correct, clean or replace
* 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. We recommend that you consult an
authorized HYUNDAI delaer 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. We recommend that the system be
checked by an authorized HYUNDAI dealer.

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. We recommend that
the fuel filter be replaced by an author-
ized HYUNDAI dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. We
recommend that the fuel lines, fuel hoses
and connections be replaced by an
authorized HYUNDAI dealer.
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.
CAUTION
When you are inspecting the belt, place the ignition switch in the
LOCK/OFF or ACC position.

Maintenance
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,
we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
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. Press the priming pump (1) severaltimes.
2. Open the air extracting hall after removing the bolt (2) using a screw-
driver to extract air.
✽✽ NOTICE
Repeat the procedure above until all the
air is out. ✽
✽
NOTICE
 Use cloths when you extract air so that the fuel is not sprayed around.
 Clean the fuel around the fuel filter or the injection pump before starting the
engine to prevent fire.
 Finally, check each part if the fuel is
leaking.
Fuel filter cartridge replacement
✽✽ NOTICE
When replacing the fuel filter cartridge,
we recommend that you use parts for
replacement from an authorized
HYUNDAI dealer.
CAUTION
If the water accumulated in the fuel filter is not drained at proper times,damages to the major parts such as
the fuel system can be caused bywater permeation in the fuel filter.
