THEFT-ALARM SYSTEM
This system helps to protect your vehicle
and valuables. The horn will sound and
the hazard warning lights will blink
continuously if any of the following
occur:
-A door is opened without using the
remote key or smart key.
-The trunk is opened without using the
remote key or smart key.
-The engine hood is opened.
The alarm continues for 30 seconds, then
the system resets. To turn off the alarm,
unlock the doors with the remote key or
smart key.
The Theft Alarm System automatically
sets 30 seconds after you lock the doors
and the trunk. For the system to activate,
you must lock the doors and the trunk
from outside the vehicle with the remote
key or smart key or by pressing the
button on the outside of the door handle
with the smart key in your possession.
The hazard warning lights will blink and
the chime will sound once to indicate the
system is armed.
Once the security system is set, opening
any door, the trunk, or the hood without
using the remote key or smart key will
cause the alarm to activate.
The Theft Alarm System will not set if the
hood, the trunk, or any door is not fully
closed. If the system will not set, check
the hood, the trunk, or the doors are fully
closed.
Do not attempt to alter this system or
add other devices to it.
Information
• Do not lock the doors until all
passengers have left the vehicle. If the
remaining passenger leaves the vehicle
when the system is armed, the alarm
will be activated.
• If the vehicle is not disarmed with the
remote key or smart key, open the
doors by using the mechanical key and
place the ignition switch in the ON
position (for remote key) or start the
engine (for smart key) and wait for 30
seconds.

Closing the hood
1. Before closing the hood, check the
following:• All filler caps in engine
compartment must be correctly
installed.
• Gloves, rags or any other
combustible material must
be removed from the engine
compartment.
2. Return the support rod to its clip to
prevent it from rattling.
3. Lower the hood halfway (lifted approximately 30 cm from the closed position) and push down to securely
lock in place. Then double check to be
sure the hood is secure.
If the hood can be raised slightly,
it is not securely locked. Open it
again and close it with more force.
WARNING
• Before closing the hood, ensure
all obstructions are removed from
around the hood opening.
• Always double check to be sure that
the hood is firmly latched before
driving away. Check there is no
hood open warning light or message
displayed on the instrument cluster.
Driving with the hood opened may
cause a total loss of visibility, which
might result in an accident.
• Do not move the vehicle with the
hood in the raised position, as vision
is obstructed, which might result in
an accident, and the hood could fall
or be damaged.

Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “Clicks”.
2. Close the fuel filler door until it is
latched securely.
Tighten the cap until it clicks one time,
otherwise the Check Engine (
) light will illuminate.
NOTICE
There may be an intermittent noise
near the refueling hole while the engine
is idling if the fuel cap is not closed
securely. This occurs normally with the
OBD system.
NOTICE
When refueling on unlevel ground,
the fuel gauge may not point to the F
position.
It is not a malfunction. If you move your
vehicle to a level ground, the fuel gauge
will move to the full position.
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.
• Do not get back into a vehicle
once you have begun refueling.
You can generate a build-up 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 refueling, always move the
shift lever 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.
• 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.
• 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.
