They are designed to help protect
the heads of the front seat occupants
and the rear outboard seat occu-
pants in certain side impact colli-
sions.
The curtain air bags are designed to
deploy only during certain side
impact collisions, depending on the
crash severity, angle, speed and
impact. The curtain air bags are not
designed to deploy in all side impact
situations, collisions from the front or
rear of the vehicle or in most rollover
situations.
WARNING
• In order for side impact and
curtain air bags to provide the
best protection, both front
seat occupants and both out-
board rear occupants should
sit in an upright position with
the seat belts properly fas-
tened.
Importantly, children should
sit in a proper child restraint
system in the rear seat.
• When children are seated in
the rear outboard seats, they
must be seated in the proper
child restraint system. Ensure
the child restraint system is
placed as far away from the
door side as possible, and
secure the child restraint sys-
tem in a locked position.

• Do not allow the passengers
to lean their heads or bodies
onto doors, put their arms on
the doors, stretch their arms
out of the window, or place
objects between the doors
and passengers when they
are seated on seats equipped
with side and/or curtain air
bags.
• Never try to open or repair any
components of the side cur-
tain air bag system. We rec-
ommend that the system be
serviced by an authorised
HYUNDAI dealer.
Failure to follow the above men-
tioned instructions can result in
injury or death to the vehicle
occupants in an accident.

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.
