Convenient Features5-14
Immobilizer System
The immobilizer system protects your
vehicle from theft. If an improperly
coded key (or other device) is used, the
engine’s fuel system is disabled.
When the ignition switch is placed in
the ON position, the immobilizer system
indicator should come on briefly, then
go off. If the indicator starts to blink, the
system does not recognize the coding of
the key.
Turn the ignition switch to the LOCK/OFF
position, then turn the ignition switch to
the ON position again.
In some circumstances, the vehicle may
not recognize your smart key if another
smart key device is nearby or a metal
object such as a key chain is causing
interference with the smart key.
If this occurs, your vehicle may not
start. Remove any metal objects or
additional keys near the smart key before
attempting to start the vehicle again.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle inoperable. WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobilizer password is a customer
unique password and should be kept
confidential.
NOTICE
The transponder in your key is an
important part of the immobilizer
system. It is designed to give years
of trouble-free service, however you
should avoid exposure to moisture,
static electricity and rough handling.
Immobilizer system malfunction could
occur.
Information
This device complies with Part 15 of the
FCC rules.
Operation is subject to the following three
conditions:
1. This device may not cause harmful
interference.
2. This device must accept any
interference received, including
interference that may cause undesired
operation.
3. Changes or modifications not expressly
approved by the party responsible
for compliance could void the user’s
authority to operate the device

Fuel Filler Door
Opening the fuel filler door
ODN8059050ODN8059050
1. Turn the engine off.
2. Ensure the driver’s door is unlocked.
3. Push the fuel filler door near the 3 o’clock position.
ODN8059051ODN8059051
3. Pull the fuel filler door (1) outward to access the fuel tank cap.
4. To remove the fuel tank cap (2), turn it counterclockwise. You may hear a
hissing noise as the pressure inside
the tank equalizes.
5. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on the
door. If necessary, spray around the door
with an approved deicer fluid (do not use
radiator antifreeze) or move the vehicle to
a warm place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn it clockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.
WARNING
Gasoline is highly flammable and
explosive. Failure to follow these
guidelines may result in SERIOUS
INJURY or DEATH:
• Read and follow all warnings posted
at the gas station.
• Before refueling, note the location of
the Emergency Gasoline Shut-Off, if
available, at the gas station.
• Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire.

05
5-71
• Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other gasoline source, with your
bare hand.
• 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.
• When refueling, always move the
shift button to the P (Park) position,
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.
• Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.• If a fire breaks out during refueling,
leave the vicinity of the vehicle, and
immediately contact 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 completely removing the cap.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
Information
Make sure to refuel your vehicle according
to the “Fuel Requirements” suggested in
the Introduction chapter.
NOTICE
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces 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.

D (Drive)
This is the normal driving position. The
tr
ansmission will automatically shift
through a 8-gear sequence, providing
the best fuel economy and power.
To start the vehicle forward, push the D
(Drive) button by depressing the brake
pedal with the engine ON. Then depress
the accelerator pedal smoothly.
For extra power when passing another
vehicle or driving uphill, depress the
accelerator fully. The transmission will
automatically downshift to the next
lower gear (or gears, as appropriate).
When the vehicle is stopped in D (Drive)
position, if you open the driver's door
with the seat belt unfastened, the gear is
shifted to P (Park) position automatically.
However when the vehicle moves in D
(Drive) position, if you open the driver's
door with the seat belt unfastened, the
gear may not shift to P (Park) position
automatically to protect the automatic
transmission.
Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the gear from
P (Park) or N (Neutral) to R (Reverse)
or D (Drive) unless the brake pedal is
depressed.
To shift the gear from P (Park) or N
(Neutral) to R (Reverse) or D (Drive):
1. Depress and hold the brake pedal.
2. Start the engine or place the ignition switch in the ON position.
3. Depress the brake pedal and push the R (Reverse) or D (Drive) button.
Stay in N (Neutral) position when
engine is Off
ODN8069006ODN8069006
ODN8069008ODN8069008If you want to keep the N (Neutral)
position after the engine is OFF, do the
following.
1. Deactivate the AUTO HOLD and release the parking brake when the
ignition switch is ON.
2. Start the engine. Push the N (neutral) button while depressing the brake
pedal. If the message ("Press and
hold OK button to stay in Neutral
when vehicle is OFF") appears on the
cluster LCD display, press and hold
the OK button on the steering wheel
for more than 1 second.
3. When the message ("Vehicle will stay in (N). Change gear to cancel")
appears on the cluster LCD display,
turn off the engine.
In this situation, if you unfasten the
driver's seat belt and open the driver's
door within 3 minutes, the gear stays in
the N (Neutral) position and the ignition
switch is turned off.
