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 vapour 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
We recommend to use unleaded
petrol which has an Octane Rating of
RON (Research Octane Number) 91
or higher.
For customers who do not use good
quality petrols including fuel addi-
tives regularly, and have problems
starting or the engine does not run
smoothly, adding one bottle of addi-
tives to the fuel tank is recommend-
ed according to the maintenance
schedule (refer to chapter 7, “Normal
Maintenance Schedule”).
Additives are available from your
authorised HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
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 use of non-approved fuels and /
or fuel additives will result in a limita-
tion 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 temperature 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. Your New Vehicle Limited
Warranty may not cover dam-
age to the fuel system and any
performance 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.)

Safety system of your vehicle
Whilst the engine is running, push
either of the switches to warm the
driver's seat or front passenger's
seat.During mild weather or under condi-
tions where the operation of the seat
warmer is not needed, keep the
switches in the OFF position.
Manual temperature control
Each time you push the switch, the
temperature setting of the seat is
changed as follows :
Automatic temperature control
The seat warmer starts to automat-
ically control the seat temperature
in order to prevent low-temperature
burns after being manually turned
ON.
If HIGH temperature is manually
selected again, the temperature
will be controlled automatically. When pressing the switch for more
than 1.5 seconds with the seat
warmer operating, the seat warmer
will turn OFF.
The seat warmer defaults to the
OFF position whenever the ignition
switch is placed to the ON position.

With the seat warmer switch in the
ON position, the heating system in the
seat turns off or on automatically
