All information in this Owner’s Manual is current at the time of pub-
lication. However, HYUNDAI reserves the right to make changes at
any time so that our policy of continual product improvement may be
carried out.
This manual applies to all HYUNDAI models and includes descrip-
tions and explanations of optional as well as standard equipment.
As a result, you may find material in this manual that does not apply
to your specific vehicle.

Seat belts must be snug against your
hips and chest to work properly.
When the seatback is reclined, the
shoulder belt cannot do its job
because it will not be snug against
your chest. Instead, it will be in front
of you. During an accident, you could
be thrown into the seat belt, causing
neck or other injuries.
The more the seatback is reclined,
the greater chance the passenger’s
hips will slide under the lap belt or
the passenger's neck will strike the
shoulder belt.
Seat cushion height
To change the height of the seat
cushion:
Push down on the lever severaltimes, to lower the seat cushion.
Pull up on the lever several times, to raise the seat cushion.
Power adjustment
The front seat can be adjusted by
using the control switches located on
the outside of the seat cushion. Before
driving, adjust the seat to the proper
position so that you can easily control
the steering wheel, foot pedals and
controls on the instrument panel.
Safety system of your vehicle
