Introduction

Petrol containing ethanol
Ethanol [E-10], a mixture of petrol
and ethanol (also known as grain
alcohol), is marketed along with or
instead of leaded or unleaded petrol.
Do not use petrol containing more
than 10% ethanol, and do not use
petrol or ethanol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system.
Discontinue using ethanol of any
kind if driveability problems occur.
Vehicle damage or driveability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Petrol containing more than 10%
ethanol.
2. Petrol or ethanol containing
methanol.
3. Leaded fuel or leaded ethanol.
Other fuels
Using fuels such as ;
- Silicone (Si) contained fuel,
- MMT (Manganese, Mn) con-
tained fuel,
- Ferrocene (Fe) contained fuel,
and
- Other metallic additives con-
tained fuels,
may cause vehicle and engine dam-
age or cause plugging, misfiring,
poor acceleration, 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 per-
formance problem caused by the use
of these fuels may not be covered by
your New Vehicle Limited
Warrenty.
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%.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and pro-
duce vapour lock or hard starting.
CAUTION
Your New Vehicle Limited
Warranty may not cover damage
to the fuel system and any per-
formance problems that are
caused by the use of fuels con-
taining methanol or fuels con-
taining MTBE (Methyl Tertiary
Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight.).
CAUTION
Never use fuel which contains
methanol. Discontinue use of
any petrol containing ethanol
which impairs drivability.

Introduction
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance 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
regularly, and have problems starting
or the engine does not run smoothly,
one bottle of additives 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.No special run-in period is needed.
By following a few simple precau-
tions for the first 1,000 km 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 emer-
gencies, to allow the brakes to seat
properly.
• Don't tow a trailer during the first
2,000 km of operation.

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 kilometres and time are shown, the fre-
quency of service is determined by whichever occurs first.
*1: 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 with other addi-
tives.
*
2: Check the engine oil level and leak every 500 km or before
starting a long trip.
*
3: The fuel filter is considered to be maintenance free but peri-
odic inspection is recommended as this maintenance
schedule depends on fuel quality. If there are some impor-
tant issues such as fuel flow restriction, surging, loss of
power, hard starting problems etc., replace the fuel filter
immediately regardless of maintenance schedule and we
recommend that you consult an authorised HYUNDAI deal-
er for details.*
4: Adjust alternator and power steering (and water pump drive
belt) and air conditioner drive belt (if equipped).
Inspect and if necessary repair or replace.
*
5 : For your convenience, it can be replaced prior to it's interval
when you do maintenance of other items.
*
6 : When adding coolant, use only deionized water or soft water
for your vehicle and never mix hard water with the coolant
filled at the factory. An improper coolant mixture can result in
serious malfunction or engine damage.
*
7: Manual transaxle fluid should be changed anytime the vehi-
cle has been submerged in water.
