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.)

SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration. The
system checks the air bag electrical
system for malfunctions. The light indi-
cates that there is a potential problem
with your air bag system, which could
include your side and/or curtain air
bags used for rollover protection (if
equipped with rollover sensor).During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol unit will inflate the front air bags,
at the time and with the force needed.
The front air bags help protect the driv-
er and front passenger by responding
to frontal impacts in which seat belts
alone cannot provide adequate
restraint. When needed, the side air
bags help provide protection in the
event of a side impact or rollover by
supporting the side upper body area.
Air bags are activated (able to inflate
if necessary) only when the ignition
switch is in the ON position.
Air bags inflate in the event of certain frontal or side collisions to help pro-
tect the occupants from serious
physical injury.
There is no single speed at which the air bags will inflate. Generally, air bags
are designed to inflate based upon
the severity of a collision and its direc-
tion. These two factors determine
whether the sensors produce an elec-
tronic deployment/inflation signal.
If your SRS malfunctions, the
air bag may not inflate properly
during an accident increasing
the risk of serious injury or
death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
The light stays on after illumi-
nating for approximately six
seconds.
The light comes on while the
vehicle is in motion.
The light blinks when the
engine is running.
We recommend that an author-
ized HYUNDAI dealer inspect the
SRS as soon as possible if any
of these conditions occur.

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 nor-
mally, the warning light ( ) will
illuminate or blink on the instru-
ment cluster. The steering wheel
may become difficult to control
or operate. Take your vehicle to
an authorized HYUNDAI dealer
and have the system checked as
soon as possible.
When abnormality is detected in the electric power steering sys-
tem, to prevent a deadly acci-
dent, the steering assist function
will stop. At this time, the warn-
ing light turns on or blinks on
the cluster. The steering wheel
may become difficult to control
or operate. Have your vehicle
checked immediately, after mov-
ing the vehicle to a safe zone.
Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be highimmediately after placing the igni-
tion switch button in the ON posi-
tion.
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.
• A click noise may be heard from the EPS relay after the ignition switch is
placed to the ON or LOCK/OFF
position.
• 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.
