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.)

Safety system of your vehicle
The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:
(1) SRS air bag warning light
(2) Retractor pre-tensioner
(3) SRS control moduleThe sensor that activates the SRS
air bag is connected with the
pre–tensioner seat belts. The SRS
air bag warning light on the instru-
ment panel will illuminate for
approximately 6 seconds after the
ignition switch is placed to the ON
position, and then it should turn off.
If the pre-tensioner is not working
properly, the warning light will illu-
minate even if the SRS air bag is
not malfunctioning. If the warning
light does not illuminate, stays illu-
minated or illuminates when the
vehicle is being driven, we recom-
mend the pre-tensioner seat belts
and/or SRS air bags be inspected
by an authorized HYUNDAI dealer
as soon as possible.• Both the driver's and front pas-
senger's pre-tensioner seat
belts may be activated in certain
frontal or side collisions.
• The pre-tensioners will be acti-
vated even if the seat belts are
not worn at the time of the colli-
sion.
• When the pre-tensioner seat
belts are activated, a loud noise
may be heard and fine dust,
which may appear to be smoke,
may be visible in the passenger
compartment. These are normal
operating conditions and are not
hazardous.
• Although it is non-toxic, the fine
dust may cause skin irritation
and should not be breathed for
prolonged periods. Wash all
exposed skin areas thoroughly
after an accident in which the
pre-tensioner seat belts were
activated.

How does the air bags system
operate?
The SRS consists of the following
components:
(1) Driver's front air bag module
(2) Passenger's front air bag module
(3) Side air bag modules
(4) Curtain air bag modules
(5) Retractor pre-tensioner assem-
blies
(6) Air bag warning light
(7) SRS control module (SRSCM)/
Rollover sensor(8) Front impact sensors
(9) Side impact sensors
(10) Side Pressure sensors
The SRSCM continually monitors
SRS components while the ignition
switch is in the ON position to deter-
mine if a crash impact is severe
enough to require air bag deploy-
ment or pre-tensioner seat belt
deployment.
SRS warning light
The SRS air bag warning light on the
instrument panel will illuminate for
about 6 seconds after the ignition
switch is turned to the ON position,
after which the air bag warning light
should go out.
ODH033104L/Q
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.

During a frontal collision, sensors will
detect the vehicle’s deceleration. If the
rate of deceleration is high enough,
the control unit will inflate the front air
bags, at the time and with the force
needed.
The front air bags help protect the
driver 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 protec-
tion in the event of a side impact.
• 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 cer-
tain frontal or side collisions to help
protect the occupants from serious
physical injury.
• Generally, air bags are designed to
inflate based upon the severity of a
collision it’s direction etc. These two
factors determine whether the sen-
sors produce an electronic deploy-
ment/inflation signal.• Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the
density and stiffness of the vehicles
or objects which your vehicle
impacts during a collision. The
determining factors are not limited
to those mentioned above.
• The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see
the air bags inflate during an acci-
dent. It is much more likely that you
will simply see the deflated air bags
hanging out of their storage com-
partments after the collision. (Continued)
•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.

Safety system of your vehicle
Why didn't my air bag go off in
a collision?
Air bags are not designed to inflate in
every collision.
There are certain types of accidents
in which the air bag would not be
expected to provide additional protec-
tion. These include rear impacts, sec-
ond or third collisions in multiple
impact accidents, as well as low
speed impacts. Damage to the vehicle
indicates a collision energy absorp-
tion, and is not an indicator of whether
or not an air bag should have inflated.
Air bag collision sensors
(if equipped)
To reduce the risk of an air bag
deploying unexpectedly and
causing serious injury or death:
•Do not hit or allow any objects
to impact the locations where
air bags or sensors are
installed.
•Do not perform maintenance
on or around the air bag sen-
sors. If the location or angle of
the sensors is altered, the air
bags may deploy when they
should not or may not deploy
when they should.
•Do not install bumper guards
or replace the bumper with a
non-genuine part. This may
adversely affect the collision
and air bag deployment per-
formance.
(Continued)
WARNING
(Continued)
•Place the ignition switch to
the LOCK/OFF or ACC posi-
tion, when the vehicle is being
towed to prevent inadvertent
air bag deployment.
•We recommend that all air bag
repairs are conducted by an
authorized HYUNDAI dealer.

Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the severity of impact of the front col-
lision.
.
Side and curtain air bags
Side and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the severity of impact
resulting from a side impact collision.Although the driver’s and front pas-
senger’s air bags are designed to
inflate only in frontal collisions, they
also may inflate in other types of col-
lisions if the front impact sensors
detect a sufficient impact. Side and
curtain air bags are designed to
inflate only in side impact collisions,
but they may inflate in other colli-
sions if the side impact sensors
detect a sufficient impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved
roads, the air bags may deploy. Drive
carefully on unimproved roads or on
surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.

Safety system of your vehicle
In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to “ride” under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
“underride” collisions.Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.

Electric Chromic Mirror (ECM)
(if equipped)
The electric rearview mirror automati-
cally controls the glare from the head-
lamp of the car behind you in night-
time or low light driving conditions.
When the engine is running, the
glare is automatically controlled by
the sensor mounted in the rearview
mirror. The sensor detects the light
level around the vehicle, and auto-
matically adjusts to control the head-
lamp glare from vehicles behind you.
Whenever the shift lever is placed in
R (Reverse), the mirror will automat-
ically go to the brightest setting in
order to improve the drivers view
behind the vehicle.
To operate the electric rearview
mirror:
• Press the ON/OFF button (1) to
turn the automatic dimming func-
tion off. The mirror indicator light
will turn off.
Press the ON/OFF button (1) to
turn the automatic dimming func-
tion on. The mirror indicator light
will illuminate.
• The mirror defaults to the ON posi-
tion whenever the ignition switch or
the Engine Start/Stop button is in
the ON position.
Outside rearview mirror
Be sure to adjust mirror angles
before driving.
Your vehicle is equipped with both
left-hand and right-hand outside
rearview mirrors.
The mirror can be adjusted remotely
with the remote switch.
The mirror heads can be folded to
prevent damage during an automatic
car wash or when passing through a
narrow street.
