Make sure that you can see backward clearly by adjusting the inside and outside
rear view mirrors properly. ( P. 133, 135)
Adjusting the mirrors
CAUTION
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.
●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.

■Power easy access system (if equipped)
The driver’s seat and steering wheel move in
accordance with engine switch mode and
the driver’s seat belt condition. ( P. 1 2 3 )
■When adjusting the seat
●Take care when adjusting the seat so that the head restraint does not touch the ceiling.
●Vehicles with folding type rear seats: When folding down a rear seatback, if it interferes
with a front seatback, adjust the front seat po sition so that the seats no longer interfere
with each other. However, if adjusting the front seat position causes the correct driving
posture to not be maintained, return the rear seatback to its original position. ( P. 121)

CAUTION
■When adjusting the seat position
●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 se
at mechanism.
●Make sure to leave enough space around the feet so they do not get stuck.
■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 rec lined, 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 ma de while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
