CAUTION
■Caution while driving
●Do not adjust the position of the driver’s seat.
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
effectiveness of the seat belt and head re straint, increasing the risk of death or
serious injury to the driver or passenger.
●Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident. The adjustment
mechanism may also be damaged.
■Adjusting the seat position
●Do not recline the seat more than necessary when the vehicle is in motion, to
reduce the risk of slid ing under the lap belt. 
If the seat is too reclined during an accident, the lap belt may slide past the hips
and apply restraint forces directly to th e abdomen or your neck may contact the
shoulder belt, increasing the ri sk of death or serious injury.
●Take care when adjusting the seat position to ensure that other passengers are
not injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury. 
Fingers or hands may become jammed in the seat mechanism.

Follow the directions given in the child restraint system installation manual and fix
the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child may be injured or
even killed in the event of sudden braking or an accident.
●When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child's sh oulder. The belt should be kept away
from the child's neck, but not so that it could fall off the child's shoulder. Failing to
do so may result in death or serious inju ry in the event of an accident or sudden
braking.
●Ensure the belt and tab are securely locked and that the seat belt is not twisted.
●Push and pull the child seat in different directions to be sure it is secure.
●Follow all installation instructions provid ed by the child restraint system manufac-
turer.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Only put a forward facing or booster child
seat on the front seat when unavoidable.
When installing a forward facing or
booster child restraint on the front passen-
ger seat, move the seat as far back as possi-
ble. Failing to do so may result in death or
serious injury if the airbags deploy (inflate).
