Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the effec-
tiveness of the seat belt and head restraint.
●Do not place anything under the front seats.
Objects placed under the front seats may be come jammed in the seat tracks and stop
the seat from locking in place. This may lead to an accident and the adjustment mech-
anism may also be damaged.
●Always observe the legal speed limit when driving on public roads.
●When driving over long distances, take regular breaks before you start to feel tired.
Also, if you feel tired or sleepy while drivin g, do not force yourself to continue driving
and take a break immediately.

●Use a child restraint system appropriate fo r the child, until the child becomes large
enough to properly wear the vehicle’s seat belt. ( →P. 5 6 )
●When the child becomes large enough to prop erly wear the vehicle’s seat belt, follow
the instructions regarding seat belt usage. ( →P. 3 8 )
