Introduction
Diesel engine
Diesel fuel
Diesel engines 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 additives, as this
will increase wear and cause dam-
age to the engine and fuel system.
The new vehicle warranty may be
invalidated if non-approved fuels
and/or fuel additives are used.
Diesel fuel of above cetane 51
should be used in your vehicle. If two
types of diesel fuel are available, use
summer or winter fuel properly
according to the following tempera-
ture 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 petrol or water enter
the tank. This would make it nec-
essary to drain it out and to bleed
the lines to avoid jamming the
injection pump and damaging the
engine.
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 specifications.
(EN stands for "European Norm"). The
use of biofuels exceeding 7% made
from rapeseed methyl ester (RME),
fatty acid methyl ester (FAME), veg-
etable oil methyl ester (VME) etc. or
mixing diesel exceeding 7% with
biodiesel will cause increased wear or
damage to the engine and fuel sys-
tem. Repair or replacement of worn or
damaged components due to the use
of non approved fuels will not be cov-
ered by the manufacturer's 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 Tyre Pressure
Warning Light
(if equipped)
This warning light illuminates:
When 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 one or more of your tyres
are significantly underinflated (The
location of the underinflated tyres
are displayed on the LCD display).
For more details, refer to
“Tyre Pressure Monitoring
System (TPMS)” in chapter 6.
This warning light remains on after
blinking for approximately 60 sec-
onds or repeatedly blinks on and off
at approximately 3 second intervals:
When there is a malfunction with
the TPMS.
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer as
soon as possible.
For more details, refer to
“Tyre Pressure Monitoring
System (TPMS)” in chapter 6.
Fuel Filter Warning
Light
(for diesel engine)
This warning light illuminates:
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 authorised HYUNDAI deal-
er as soon as possible.
NOTICE
Safe Stopping
The TPMS cannot alert you to
severe and sudden tyre dam-
age caused by external factors.
If you notice any vehicle insta-
bility, immediately take your
foot off the accelerator pedal,
apply the brakes gradually with
light force, and slowly move to
a safe position off the road.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when
travelling on smooth, level road.
When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmissiom
occurs, check the transmissiom fluid
level.
Check the automatic transmission/
dual clutch transmission P (Park)
function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal). Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm, whilst running the
diesel engine. The high currents
of the electronic engine control
system produce a considerable
amount of magnetic fields.
