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.

Maintenance
Engine compartment precautions
(Diesel engine)
• Follow the safety tips provided below,
when you are checking the engine bay
whilst the engine is running.
- Do not touch the injector, injector
wirings, and the engine computer
whilst the engine is running.
- Do not remove the injector connector
whilst the engine is running.
- People using pacemakers must not
go near the engine whilst the engine
is starting or running.
WARNING- Maintenance
work
• Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured whilst
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
authorised HYUNDAI dealer.
• Working under the bonnet 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 whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before getting
near the engine or cooling fans.
WARNING- Diesel Engine
Never work on injection system
with engine running or within 30
seconds after shutting off engine.
High-pressure pump, rail, injectors
and high-pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touches the body.
People using pacemakers should
not move within 30cm of the ECU or
wiring harness within the engine
room whilst engine is running, high
currents used in the electronic
engine control system produce
considerable magnetic fields.
CAUTION
• Do not put heavy objects or apply
excessive force on top of the
engine cover (if equipped) or fuel
related parts.
• When you inspect the fuel system
(fuel lines and fuel injection
devices), we recommend that you
contact an authorised 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 flammable 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 electric
current.
• 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.

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 for
proper tension and adjusted as neces-
sary.
Fuel filter
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 authorised HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorised HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.
WARNING - Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off engine.
High pressure pump, rail, injectors
and high pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touch the body.
People using pacemakers should
not move within 30 cm of the ECU
or wiring harness within the engine
room whilst engine is running, high
currents used in the Common Rail
system produce considerable mag-
netic 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 its
bottom.
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 authorised
HYUNDAI dealer and have
drain the water and checked
the system.
Extracting air from the fuel filter
If you drive until you have no fuel left or if
you replace the fuel filter, be sure to
extract air from the fuel system as it
makes it difficult to start the engine.
1. Pump up and down(1) approximately
50 times until the pump is hard.
2. Extract air from the fuel filter by remov-
ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
3. Pump up and down(1) approximately
15 times.
4. Extract air from the fuel filter by remov-
ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
5. Pump up and down(1) approximately 5
times.
✽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,
use HYUNDAI genuine parts.
CAUTION
If the water accumulated in the fuel
filter is not drained, damages to the
major parts such as the fuel system
can be caused by water permeation
in the fuel filter.
