Introduction
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 vapor lock or hard starting.
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 gasoline which has an
octane rating of RON (Research
Octane Number) 95 / AKI (Anti Knock
Index) 91 or higher (for Europe) or
Octane Rating of RON (Research
Octane Number) 91 / AKI (Anti-Knock
Index) 87 or higher (except Europe).
For customers who do not use good
quality gasolines including fuel addi-
tives 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 (for
Europe)/ 5,000km (except Europe).
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.

Maintenance
BATTERY
For best battery service
•Keep the battery securely mounted.
•Keep the battery top clean and dry.
•Keep the terminals and connec-
tions clean, tight, and coated with
petroleum jelly or terminal grease.
•Rinse any spilled electrolyte from
the battery immediately with a
solution of water and baking soda.
•If the vehicle is not going to be
used for an extended time, discon-
nect the battery cables.
Information
Basically equipped battery is
maintenance free type. If your
vehicle is equipped with the bat-
tery marked with LOWER and
UPPER on the side, you can check
the electrolyte level. The elec-
trolyte level should be between
LOWER and UPPER. If the elec-
trolyte level is low, it needs to add
distilled (demineralized) water
(Never add sulfuric acid or other
electrolyte). When refill, be careful
not to splash the battery and adja-
cent components. And do not
overfill the battery cells. It can
cause corrosion on other parts.
After then ensure that tighten the
cell caps. We recommend that you
contact an authorized HYUNDAI
dealer.
i
Battery dangers
Always read the follow-
ing instructions carefully
when handling a battery.
Keep lighted cigarettes
and all other flames or
sparks away from the
battery.
Hydrogen, a highly com-
bustible gas, is always
present in battery cells
and may explode if ignit-
ed.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC
ACID. Do not allow bat-
tery acid to contact your
skin, eyes, clothing or
paint finish.
