Introduction
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 type
diesel 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.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 jamming
the injection pump and damaging
the engine.
- Diesel Fuel
(if equipped with DPF)
It is recommended to use the reg-
ulated automotive diesel fuel for
diesel vehicle equipped with the
DPF system.
If you use diesel fuel including
high sulfur (more than 50 ppm sul-
fur) and unspecified additives, it
can cause the DPF system to be
damaged and white smoke can be
emitted.
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.
Never use any fuel, whether
diesel, B7 biodiesel or other-
wise, that fails to meet the latest
petroleum industry specifica-
tion.
Never use any fuel additives or
treatments that are not recom-
mended or approved by the
vehicle manufacturer.

Convenient features of your vehicle
Low Tire Pressure
Warning Light
(if equipped)
Low tire pressure telltale
The low tire pressure telltale comes
on for 3 seconds after the ignition
switch is turned to the "ON" position.
The low tire pressure telltale will illu-
minate after it blinks for approximate-
ly one minute when there is a prob-
lem with the Tire Pressure
Monitoring System.
If this occurs, we recommend that
the system be checked by an author-
ized HYUNDAI dealer.
For details, refer to the TPMS on
chapter 6.
Fuel Filter Warning
Light (Diesel Engine)
This warning light illuminates:
Once you turn the ignition switch or
Engine Start/Stop button to the ON
position.
- It illuminates for approximately 3
seconds and then goes off.
When water has accumulated
inside the fuel filter.
In this case, remove the water from
the fuel filter.
For more details, refer to “Fuel
Filter” in chapter 7.
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 an authorized HYUNDAI deal-
er as soon as possible.
NOTICE
Safe stopping
The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors.
If you feel any vehicle instabil-
ity, immediately take your foot
off the accelerator, apply the
brakes gradually and with
light force, and slowly move to
a safe position off the road.

Maintenance
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 subject to high pres-
sure 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 more than
30cm closer to the ECU or
wiring harness within the
engine room while engine is
running, since the high currents
in the electronic engine control
system produce considerable
magnetic fields.
WARNING (Continued)
When you remove the interior
trim cover with a flat head (-)
driver, be careful not to damage
the cover.
Be careful when you replace and
clean bulbs to avoid burns or
electrical shock.

Maintenance
I : Inspect and if necessary, adjust, correct, clean or replace.
R : Replace or change.
*
1: Adjust alternator and power steering (and water pump drive belt) and air conditioner drive belt (if equipped).
Inspect and if necessary correct or replace.
*
2: Check the engine oil level and leak every 500 km (350 miles) or before starting a long trip.
*3: If good quality gasolines that meet Europe Fuel standards (EN228) or equivalents including fuel additives is not available, one
bottle of additive is recommended. Additives are available from your authorized HYUNDAI dealer along with information on how
to use them. Do not mix other additives.
*
4: For your convenience, it can be replaced prior to it's interval when you do maintenance of other items.
*5: 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.

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.
When you are inspecting the belt,
place the ignition switch in the
LOCK/OFF or ACC position.
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 excessive amount of
foreign matter accumulates 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 authoized HYUNDAI
dealer.
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 an authoized HYUNDAI
dealer.
NOTICE
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 subject to high pres-
sure even after the engine
stopped. The fuel jet produced
by fuel leaks may cause serious
injury, if it touch the body.
People using pacemakers
should not move than 30cm
closer to the ECU or wiring har-
ness within the engine room
while engine is running, since
the high currents in the
Common Rail system produce
considerable magnetic fields.

Draining water from 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 turned
on, we recommend that the
system be serviced by an
authorized HYUNDAI dealer.
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 by water permeation in the
fuel filter.
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 sys-
tem as it makes it difficult to start the
engine.
1. Pump up and down(1) approxi-
mately 50 times until the pump is
hard.
2. Extract air from the fuel filter by
removing the bolt(2) with a cross-
tip screw driver and reinstall the
bolt(2).
3. Pump up and down(1) approxi-
mately 15 times.4. Extract air from the fuel filter by
removing the bolt(2) with a cross-
tip screw driver and reinstall the
bolt(2).
5. Pump up and down(1) approxi-
mately 5 times.
Information
• 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 start-
ing the engine to prevent fire.
• Finally, check each part if the fuel is
leaking.
