F8
Introduction
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. "E85" is not compati-
ble with your vehicle. Use of "E85"
may result in poor engine perform-
ance and damage to your vehicle's
engine and fuel system. HYUNDAI
recommends that customers do not
use fuel with an ethanol content
exceeding 15 percent.
To prevent damage to your vehicle’s
engine and fuel system:
Never use gasohol which con- tains methanol.
Never use gasohol containing more than 15% ethanol.
Never use leaded fuel or leaded gasohol.
Never use "E85" fuel.
Your New Vehicle Limited
Warranty does not cover damage
to the fuel system or any perform-
ance problems caused by the use
of "E85" fuel.
Using Fuel Additives (except Detergent Fuel Additives)
Using fuel additives such as:
- Silicone fuel additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, dam-
age to the catalyst, or abnormal cor-
rosion, and may cause damage to
the engine resulting in a reduction in
the overall life of the powertrain.
- The Malfunction Indicator Lamp
(MIL) may illuminate.
Damage to the fuel system or per-
formance problem caused by the
use of these fuels or fuel additives
may not be covered by your New
Vehicle Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives
such as
MMT (Methylcyclopentadienyl
Manganese Tricarbonyl
).
HYUNDAI does not recommend the
use of gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Detergent Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with
detergent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance performance
of the Emission Control System. For
more information on TOP TIER
Detergent Gasoline, please go to the
website (www
.toptiergas.com).

Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exteriorsurfaces 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.
NOTICE
i(Continued)
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.
When refueling, always move
the shift lever to the P (Park)
position (for automatic transmis-
sion/
dual clutch transmission)
or first gear or R (Reverse, for
manual transmission), set the
parking brake, and place the
ignition switch to the LOCK/OFF
position. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire.
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.
(Continued)
(Continued)
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.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.

Average fuel economy/Instant fuel economy
Average Fuel Economy (1)
The average fuel economy is calcu-
lated by the total driving distance
and fuel consumption since the last
average fuel economy reset.
The average fuel economy can be reset both manually and automati-
cally.
Manual reset
To clear the average fuel economy
manually, press the OK button on the
steering wheel for more than 1 sec-
ond when the average fuel economy
is displayed.
Automatic reset
To automatically reset the average
fuel economy, select between "After
Ignition" or "After Refueling" in the
User Settings mode on the LCD dis-
play.
- After Ignition: When the engine hasbeen OFF for 4 hours or longer the

Driving your vehicle
The dual clutch transmission incor- porates a dry-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency while driv-
ing. But it differs from a conven-
tional automatic transmission
because it does not incorporate a
torque converter. Instead, the tran-
sition from one gear to the next is
managed by clutch slip, especially
at lower speeds. As a result, shifts
are sometimes more noticeable,
and a light vibration can be felt as
the transmission shaft speed is
matched with the engine shaft
speed. This is a normal condition of
the dual clutch transmission.
The dry-type clutch transfers torque more directly and provides
a direct-drive feeling which may
feel different from a conventional
automatic transmission. This may
be more noticeable when launch-
ing the vehicle from a stop or when
traveling at low, stop-and-go vehi-
cle speeds. When rapidly accelerating from a
lower vehicle speed, the engine
rpm may increase dramatically as
a result of clutch slip as the dual
clutch transmission selects the cor-
rect gear. This is a normal condi-
tion.
When accelerating from a stop on an incline, press the accelerator
smoothly and gradually to avoid
any shudder feeling or jerkiness.
When traveling at a lower vehicle speed, if you release the accelera-
tor pedal quickly, you may feel
engine braking before the trans-
mission changes gears. This
engine braking feeling is similar to
operating a manual transmission at
low speed.
When driving downhill, you may wish to move the gear shift lever to
Manual Shift mode and downshift
to a lower gear in order to control
your speed without using the brake
pedal excessively.
When you turn the engine on and off, you may hear clicking sounds
as the system goes through a self-
test. This is a normal sound for the
dual clutch transmission. During the first 1000 miles, you
may feel that the vehicle may not
be smooth when accelerating at
low speed. During this break-in
period, the shift quality and per-
formance of your new vehicle is
continuously optimized.
To reduce the risk of serious
injury or death:
ALWAYS check the surround-
ing areas near your vehicle for
people, especially children,
before shifting a vehicle into
D (Drive) or R (Reverse).
Before leaving the driver's
seat, always make sure the
shift lever is in the P (Park)
position, then set the parking
brake, and place the ignition
switch in the LOCK/OFF posi-
tion. Unexpected and sudden
vehicle movement can occur
if these precautions are not
followed. (Continued)
