WARNING
■
For safe driving
Observe the following precautions.
Failure to do so may result in death or
serious injury. A
B
C
D ●
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 pos-
ture from being achieved, and reduce
the effectiveness of the seat belt and
head restraint. ●
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
and the adjustment mechanism 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
driving, do not force yourself to con-
tinue driving and take a break immedi-
ately.

gers are not injured by the moving
seat.●
Do not put your hands under the seat
or near the moving parts to avoid
injury.

Seat adjustment
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 shoulder 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.

Do not operate the front passenger’s seat
when a passenger is seated in it. In addi-
tion, do not let anyone sit down in the
front passenger’s seat while the seat is
being operated or when the head
restraint is being folded. The front pas-
senger may catch their legs between the
instrument panel and seat, or the head
restraint may interfer e with their head,
resulting in injury. ■
When the front passenger’s seat is
folded forward
If the outside rear view mirror is difficult
to see, due to the position of the front
passenger’s seat, mo ve the front passen-
ger’s seat to an appropriate position.
