Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you use unleaded
gasoline which has an octane rating of
RON (Research Octane Number) 95 /
AKI (Anti Knock Index) 91 or higher.
You may use unleaded gasoline with
an octane rating of RON 91-94 / AKI
87-90 but it may result in slight per-
formance reduction of the vehicle. (Do
not use methanol blended fuels)
Except Europe
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index)
87 or higher. (Do not use methanol
blended fuels)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
NOTICE
•Do not "top off" after the noz-
zle automatically shuts off
when refueling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental
to the catalytic converter and
will damage the engine control
system’s oxygen sensor and
affect emission control.
Never add any fuel system
cleaning agents to the fuel tank
other than what has been speci-
fied (We recommend that you
consult an authorized HYUNDAI
dealer for details.)

Convenient features of your vehicle
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 occurs:
- 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 automati-
cally sets 30 seconds after you lock
the doors and the trunk. For the sys-
tem 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 handles 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, open-
ing 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 pas-
sengers 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.
• When the system is disarmed but a
door or trunk is not opened within 30
seconds, the system will be rearmed.

STEERING WHEEL
Electric power steering (EPS)
The system assists you with steering
the vehicle. If the engine is off or if
the power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Also, the steering effort becomes
heavier as the vehicle’s speed
increases and becomes lighter as
the vehicle’s speed decreases for
better control of the steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend
that the system be checked by an
authorized HYUNDAI dealer.If the Electric Power Steering
System does not operate normal-
ly, the warning light ( ) will illu-
minate on the instrument cluster.
The steering wheel may become
difficult to control or operate. Take
your vehicle to an authorized
HYUNDAI dealer and have the sys-
tem checked as soon as possible.
Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the igni-
tion switch or the Engine Start/Stop
button in the ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics is completed,
the steering wheel will return to its
normal condition.
(Continued)(Continued)
• A click noise may be heard from the
EPS relay after the ignition switch is
placed to the ON or LOCK/OFF
position (Without Smart key system).
A click noise may be heard from the
EPS relay after the Engine Start/Stop
button is in the ON or OFF position.
(With Smart key system)
• Motor noise may be heard when the
vehicle is at a stop or at a low driv-
ing speed.
• When you operate the steering
wheel in low temperature, abnormal
noise may occur. If temperature
rises, the noise will disappear. This
is a normal condition.
• When the vehicle is stationary, if
you turn the steering wheel all the
way to the left or right continuously,
the steering wheel effort increases.
This is not a system malfunction. As
time passes, the steering wheel
effort will return to its normal con-
dition.

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.
NOTICE
i
(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)
(Continued)
•Always check that the fuel cap
is installed securely to prevent
fuel spillage in the event of an
accident.
(Continued)
•When refueling, always move
the shift lever to the P (Park)
position (for automatic trans-
mission) or first gear or R
(Reverse, for manual trans-
mission), 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.

operate properly, do not drive the
vehicle. We recommend you to
have the vehicle inspected by an
authorized HYUNDAI dealer.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure is
required to stop the vehicle.
