Other fuels
Using fuels such as;
- Silicone (Si) contained fuel,
- MMT (Manganese, Mn) contained fuel,
- Ferrocene (Fe) contained fuel, and
- Other metallic additives contained
fuels,
may cause vehicle and engine damage
or cause plugging, misfiring, poor accel-
eration, engine stalling, catalyst melting,
abnormal corrosion, life cycle reduction,
etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
✽ NOTICE
Damage to the fuel system or perform-
ance problem caused by the use of these
fuels may not be covered by your New
Vehicle Limited Warranty.
Use of MTBE
HYUNDAI recommends avoiding fuels
containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapour lock or hard starting.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system, engine control system
and emission control system.
Fuel Additives
HYUNDAI recommends that you use
unleaded petrol which has an Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index) 87
or higher.
For customers who do not use good
quality petrol including fuel additives reg-
ularly, and have problems starting or the
engine does not run smoothly, one bottle
of additives should be added to the fuel
tank at every 15,000km. Additives are
available from your authorised HYUNDAI
dealer along with information on how to
use them.
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.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuel
system and any performance prob-
lems that are caused by the use of
fuels containing methanol or fuels
containing MTBE (Methyl Tertiary
Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight.)

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.

Biodiesel (for New Zealand)
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), 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 manufacturers warranty.No special run-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
• Do not race the engine.
• Whilst driving, keep your engine speed
(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
• Do not maintain a single speed for long
periods of time, either fast or slow.
Varying engine speed is needed to
properly run-in the engine.
• Avoid hard stops, except in emergen-
cies, to allow the brakes to seat prop-
erly.
• Don't tow a trailer during the first 2,000
km (1,200 miles) of operation.
VEHICLE RUN-IN PROCESS
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
NORMAL MAINTENANCE SCHEDULE
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.
*
1: Inspect drive belt tensioner, idler and alternator pulley and
if necessary correct or replace.
*
2: The engine oil level should be checked regularly and main-
tained properly. Operating with an insufficient amount of oil
can damage the engine, and such damage is not covered
by warranty.
*
3: Check the engine oil level and leak every 500 km or before
starting a long trip.
*
4: If good quality petrol meeting Europe Fuel standards
(EN228) or equivalent, including fuel additives is not avail-
able, one bottle of additive is recommended. Additives are
available from your authorised HYUNDAI dealer along with
information on how to use them. Do not mix other additives.
*
5: 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 15,000km
replacement".
If there are some important safety matters like fuel flow
restriction, surging, loss of power, hard starting problem
etc., replace the fuel filter immediately regardless of main-
tenance schedule and consult an authorised HYUNDAI
dealer for details.*
6: For your convenience, it can be replaced prior to it's interval
when you do maintenance of other items.
*
7: Inspect for excessive valve noise and/or engine vibration
and adjust if necessary. An authorised HYUNDAI dealer
should perform the operation.
*
8: The fuel filter is considered to be maintenance free but peri-
odic inspection is recommended for this maintenance
schedule depends on fuel quality. If there are some impor-
tant matters like fuel flow restriction, surging, loss of power,
hard starting problem etc, replace the fuel filter immediate-
ly regardless of maintenance schedule and consult an
authorised HYUNDAI dealer for details.
*
9: When adding coolant, use only deionized water or soft
water for your vehicle and never mix hard water in the
coolant filled at the factory. An improper coolant mixture can
result in serious malfunction or engine damage.
