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

Customization
Some functions can be customized.
(  P.466) WARNING●
Do not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result , the seat belt pre-
tensioner for the front passenger’s seat
may not activate in the event of a colli-
sion.●
If the pretensioner has activated, the
SRS warning light will come on. In that
case, the seat belt cannot be used
