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.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 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.
CAUTION
• Never use any fuel, whether
diesel, B7 biodiesel or other-
wise, that fails to meet the lat-
est petroleum industry speci-
fication.
• Never use any fuel additives
or treatments that are not rec-
ommended or approved by the
vehicle manufacturer.

Features of your vehicle
Door Ajar Warning Light
This warning light illuminates:
When a door is not close securely.
Tailgate Open Warning
Light
This warning light illuminates:
When the tailgate is not close
securely.
Fuel Filter Warning Light
(Diesel Engine)
This warning light illuminates:
• Once you set 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.
CAUTION - Fuel Filter
Warning Light
• When the Fuel Filter Warning
Light illuminates, engine
power (vehicle speed & idle
speed) may decrease.
• If you keep driving with the
warning light on, engine parts
(injector, common rail, high
pressure fuel pump) may be
damaged. If this occurs, we
recommend that you have the
vehicle inspected by an
authorized HYUNDAI dealer as
soon as possible.

Maintenance
Engine compartment precau-
tions (Diesel engine)
• The piezo injector operates at high
voltage (maximum 200v).
Therefore, the following accidents
may occur.
- Direct contact with the injector or
injector wiring may cause electric
shock or damage your muscle or
nerve system.
- The electromagnetic wave from
the operating injector may cause
the artificial heart pacemaker to
malfunction.
• Follow the safety tips provided
below, when you are checking the
engine room while the engine is
running.
- Do not touch the injector, injector
wirings, and the engine computer
while the engine is running.
- Do not remove the injector con-
nector while the engine is run-
ning.
- People using pacemakers must
not go near the engine while the
engine is starting or running.
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 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 than 30cm
closer to the ECU or wiring har-
ness within the engine room
while engine is running, since
the high currents in the elec-
tronic engine control system
produce considerable magnetic
fields.(Continued)
• When you remove the interior
trim cover with a flat head (-)
driver, be careful not to dam-
age 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 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 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 connectionsr be
replaced by an authoized HYUNDAI
dealer.
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 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.
CAUTION
When you are inspecting the
belt, place the ignition switch in
the LOCK/OFF or ACC position.
