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.
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 contain-
ing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen
Content 2.7% weight.)
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, and have problems
starting or the engine does not run
smoothly, one bottle of additive added
to the fuel tank is recommended
according to the maintenance sched-
ule (refer to chapter 7, “Normal
Maintenance Schedule”).
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
• Observe all regulations regarding
registration and insurance.
• Determine that acceptable fuel is
available.

Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type
of fuel spilled on painted sur-
faces may damage the paint.
• If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can
result in a serious malfunction
of the fuel system or emission
control system.

(Continued)
•When refueling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.
•When using an approved
portable fuel container, be sure
to place the container on the
ground prior to refueling. Static
electricity discharge from the
container can ignite fuel vapors
causing a fire. Once refueling
has begun, contact between
your bare hand and the vehicle
should be maintained until the
filling is complete.
•Use only approved portable
plastic fuel containers designed
to carry and store gasoline.
(Continued)
(Continued)
•Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle while at a gas station,
especially during refueling.
•Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
•If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station and then contact the
local fire department. Follow
any safety instructions they
provide.
•If pressurized fuel sprays out,
it can cover your clothes or
skin and thus subject you to
the risk of fire and burns.
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.

(Continued)
•Always check that the fuel cap
is installed securely to prevent
fuel spillage in the event of an
accident.

The speedometer indicates the
speed of the vehicle and is calibrated
in kilometers per hour (km/h) and/or
miles per hour (MPH).
The speedometer for cluster type B
is displayed differently according to
the mode selected, ECO or SPORT.
If the shift lever is in S (Sport),
SPORT mode is selected and if the
shift lever is in D (Drive), ECO mode
is selected.
For more information, refer to
“Dual Clutch Transmission” in
chapter 5.
Tachometer
The tachometer indicates the approx-
imate number of engine revolutions
per minute (rpm).
Use the tachometer to select the cor-
rect shift points and to prevent lug-
ging and/or over-revving the engine.
Do not operate the engine within
the tachometer's RED ZONE. This
may cause severe engine damage.
Power gauge
The power gauge indicates whether
the current driving condition is fuel
efficient or not.
• CHARGE :
Shows that the energy made by the
vehicle is being converted to elec-
trical energy. (Regenerated energy)
• ECO :
Shows that the vehicle is being
driven in an Eco-friendly manner.
• POWER :
Shows that the vehicle is exceed-
ing the Eco-friendly range.

chapter 8.
• The fuel gauge is supplemented by a
low fuel warning light, which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank.
