Reasons given... Consider...
“I have an airbag” Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea.Peoplewho are
ejected are 40 times more likely
to DIE.Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.
WARNING:Do not sit on top of a buckled safety belt or insert a
latchplate into the buckle to avoid the Belt-Minderchime. To
do so may adversely affect the performance of the vehicle’s airbag
system.
Deactivating/activating the Belt-Minderfeature

deactivated/activated independently. When deactivating/activating
one seating position, do not buckle the other position as this will
terminate the process.
