gers are not injured by the moving seat.
● Do  not  put  your  hands  under  the  seat  or  near  the  moving  parts  t o  avoid
injury.
Fingers or hands may become jammed in the seat mechanism.

● To  reduce  the  risk  of  sliding  under  the  lap  belt  during  a  colli sion,  do  not
recline the seat more than necessary. 
If  the  seat  is  too  reclined,  the  lap  belt  may  slide  past  the  hi ps  and  apply
restraint  forces  directly  to  the  abdomen,  or  your  neck  may  cont act  the
shoulder belt, increasing  the risk of death  or  serious  injury i n the  event of
an accident. 
Adjustments should not be made while driving as the seat may un expect-
edly move and cause the driver to lose control of the vehicle.
● After adjusting the seat, make sure that the seat is locked in position.
