231-1. 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.119)
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.119)
Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
( P.135)
Wear the seat belt correctly.
( P.24) Make sure that all occupants are wear-
ing their seat belts before driving the
vehicle. (
P.24)
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.140, 141)
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
When the vehicle speed reaches
approximately 12 mph (20 km/h) or
higher, the seat belts will retract slightly
to remove any slack.
If the system determines that a collision
is unavoidable, the front seat belts will
retract before the collision. ( P.206)
■Pre-collision seat belts with comfort
function
A motor sound may be heard when a front
seat belt is released or a front door is
opened. This does not indicate a malfunc-
tion.
■Customization
Some functions can be customized.
(  P.470)
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
again and must be replaced at your
Lexus dealer.

fort function (front seats of vehi-
