Safety system of your vehicle
2
When the vehicle stops suddenly, or
if the occupant tries to lean forward
too quickly, the seat belt retractor will
lock into position. In certain frontal
collisions, the pre-tensioner will acti-
vate and pull the seat belt into tighter
contact against the occupant's body.
If the system senses excessive tension
on the driver or passenger's seat belt
when the pre-tensioner system acti-
vates, the load limiter (if equipped)
inside the retractor pre-tensioner will
release some of the pressure on the
affected seat belt.
Always wear your seat belt and
sit properly in your seat.
Do not use the seat belt if it is
loose or twisted. A loose or
twisted seat belt will not pro-
tect you properly in an acci-
dent.
Do not place anything near the
buckle. This may adversely
affect the buckle and cause it
to function improperly.
Always replace your pre-ten-
sioners after activation or an
accident.
NEVER inspect, service, repair
or replace the pre-tensioners
yourself. This must be done by
an authorised HYUNDAI dealer.
Do not hit the seat belt assem-
blies.
WARNING
Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
deploys during a collision, the
pre-tensioner can become hot
and can burn you.
WARNING
Body work on the front area of
the vehicle may damage the
pre-tensioner seat belt system.
Therefore, we recommend the
system to be serviced by an
authorised HYUNDAI dealer.
