Always be sure that you and all vehi-
cle occupants are seated properly
and wearing the seat belt properly for
the most effective protection by the
air bag and the seat belt.
The OCS may not function properly if
the passenger takes actions which
can affect the classification system.
These include:
Failing to sit in an upright position.
Leaning against the door or centerconsole.
Sitting towards the sides of the front of the seat.
Putting their legs on the dashboard or resting them on other locations
which reduce the passenger
weight on the front seat.
Wearing the seat belt improperly.
Reclining the seatback.
Wearing a thick cloth like ski wear or hip protection wear.
Putting an additional thick cushion on the seat.
Putting electrical devices (e.g. notebook, satellite radio) on the
seat with inverter charging.Condition and operation in the front passenger Occupant Classification System

passenger seat, the system may recognize him/her as a child depending on his/her physique
and posture.

2Do not allow children to ride in the front passenger seat. When a larger child who has out- grown a child restraint system sits in the front passenger seat, the system may recognize
him/her as an adult depending upon his/her physique or sitting position.
*
3Never install a child restraint system on the front passenger seat.
*4The PASSENGER AIR BAG "OFF" indicator may turn on or off when a child above 12 months
to 12 years old (with or without child restraint system) sits in the front passenger seat. This is
a normal condition.

Air bag inflation conditions
Front air bags
Front air bags and the driver's knee
air bag are designed to inflate in a
frontal collision depending on the
severity, speed, or angles of impact
of the front collision.
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, speed, or
angles 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
or rollover situations, but they may
inflate in other collisions 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.

Air bag non-inflation conditions
In certain low-speed collisions the air
bags may not deploy. The air bags
are designed not to deploy in such
cases because they may not provide
benefits beyond the protection of the
seat belts.Front air bags are not designed to
inflate in rear collisions, because
occupants are moved backward by
the force of the impact. In this case,
inflated air bags would not provide
any additional benefit.
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide addi-
tional occupant protection.
However, side and curtain air bags
may inflate depending on the severi-
ty, vehicle speed and angles of
impact.

Electric Power Steering (EPS)
The system assists you with steering
the vehicle. If the engine is turned off
or if the power steering system
becomes inoperative, you may still
steer the vehicle, but it will require
increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the system
checked by an authorized HYUNDAI
dealer.
Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the igni-
tion switch 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.
• A click noise may be heard from the EPS relay after the ignition switch is
in the ON or 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.
i
If the Electric Power Steering
System does not operate nor-
mally, the warning light ( ) will
illuminate on the instrument
cluster. You may steer the vehi-
cle, but it will require increased
steering efforts. Take your vehi-
cle to an authorized HYUNDAI
dealer and have the system
checked as soon as possible.
