WARNING
Do not recline the seatback
excessively while driving.
To reduce the risk of sliding under
the lap belt during a collision, do
not recline the seat more than
necessary. If the seat is too
reclined, the lap belt may slide
past the hips and apply restraint
forces directly to the abdomen, or
your neck may contact the shoul-
der belt, increasing the risk of
death or serious injury in the
event of an accident. Adjustments
should not be made while driving
as the seat may unexpectedly
move and cause the driver to lose
control of the vehicle.
WARNING
Make sure that all passengers
wear their seat belt correctly.
Use of seat belts may be manda-
tory under local laws and regula-
tions. If a seat belt is not worn
properly, an occupant may con-
tact interior parts or be thrown
from the vehicle in the case of
sudden braking or a collision, pos-
sibly resulting in death or serious
injury. Also, if an occupant has an
incorrect riding posture, the air-
bags will be ineffectual as occu-
pant protection devices and may
actually cause injuries when they
deploy.
