251-1. For safe use
1
For safety and security
Adjust the angle of the seatback so
that you are sitting straight up and
so that you do not have to lean for-
ward to steer. (P.117)
Adjust the seat so that you can
depress the pedals fully and so that
your arms bend slightly at the
elbow when gripping the steering
wheel. ( P.117)
Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
(  P.132)
Wear the seat belt correctly.
(  P.26) Make sure that all occupants are wear-
ing their seat belts before driving the
vehicle. (
P.26)
Use a child restraint system appropri-
ate for the child until the child becomes
large enough to properly wear the
vehicle’s seat belt. ( P.45)
Make sure that you can see backward
clearly by adjusting the inside and out-
side rear view mirrors properly.
(  P.136, 137)
For safe driving
For safe driving, adjust the seat and
mirror to an appropriate position
before driving.
Correct driving posture
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.
Correct use of the seat belts
Adjusting the mirrors

281-1. For safe use
1To fasten the seat belt, push the
plate into the buckle until a click
sound is heard.
2 To release the seat belt, press the
release button .
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sud-
den stop or on impact. It may also lock if you
lean forward too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is com-
pletely extended and then retracted even
slightly, the belt is locked in that position and
cannot be extended. This feature is used to
hold the child restraint system (CRS) firmly.
To free the belt again, fully retract the belt
and then pull the be lt out once more.
( P.45)
1 Push the seat belt shoulder anchor
down while pressing the release
button .
2 Push the seat belt shoulder anchor
up while pressing the release but-
ton .
Move the height adjuster up and down as
needed until you hear a click.
WARNING
●Do not use the seat belt extender
when installing a child restraint system
because the belt will not securely hold
the child restraint system, increasing
the risk of death or serious injury in the
event of an accident.
●The personalized extender may not be
safe on another vehicle, when used by
another person, or at a different seat-
ing position other than the one origi-
nally intended.
NOTICE
■When using a seat belt extender
When releasing the se at belt, press on
the buckle release button on the
extender, not on the seat belt.
This helps prevent damage to the vehicle
interior and the extender itself.

anchor height (front seats)
WARNING
■Adjustable shoulder anchor
Always make sure the shoulder belt is
positioned across the center of your
shoulder. The belt should be kept away
from your neck, but not falling off your
shoulder. Failure to do so could reduce
the amount of protection in an accident
and cause death or serious injuries in the
event of a sudden stop, sudden swerve or
accident.
