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.97)
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.97)
Lock the head restraint in place 
with the center of the head restraint 
closest to the top of your ears. 
( P.103)
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.40)
Make sure that you can see backward 
clearly by adjusting the inside and out-
side rear view mirrors properly. 
( P.107, 108)
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

241-1. For safe use
Seat belts
Make sure that all occupants are 
wearing their seat belts before driv-
ing the vehicle.
WARNING
Observe the following precautions to 
reduce the risk of injury in the event of 
sudden braking, sudden swerving or an 
accident.
Failure to do so may cause death or seri-
ous injury.
■Wearing a seat belt
●Ensure that all passengers wear a seat 
belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one 
person only. Do not use a seat belt for 
more than one person at once, includ-
ing children.
●Lexus recommends that children be 
seated in the rear seat and always use 
a seat belt and/or an appropriate child 
restraint system.
●To achieve a proper seating position, 
do not recline the seat more than nec-
essary. The seat belt is most effective 
when the occupants are sitting up 
straight and well back in the seats.
●Do not wear the shoulder belt under 
your arm.
●Always wear your seat belt low and 
snug across your hips.
■Pregnant women
Obtain medical advice and wear the seat 
belt in the proper way. (
P.25)
Women who are pregnant should posi-
tion the lap belt as low as possible over 
the hips in the same manner as other 
occupants, extending the shoulder belt 
completely over the shoulder and avoid-
ing belt contact with the rounding of the 
abdominal area.
If the seat belt is not worn properly, not 
only the pregnant woman, but also the 
fetus could suffer death or serious injury 
as a result of sudden braking or a colli-
sion.
■People suffering illness
Obtain medical advice and wear the seat 
belt in the proper way. (
P.25)
■When children are in the vehicle
Do not allow children to play with the 
seat belt. If the seat belt becomes twisted 
around a child’s neck, it may lead to 
choking or other serious injuries that 
could result in death.
If this occurs and the buckle cannot be 
unfastened, scissors should be used to 
cut the belt.
■Seat belt damage and wear
●Do not damage the seat belts by allow-
ing the belt, plate, or buckle to be 
jammed in the door. 

261-1. 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 lock ed in that position and 
cannot be extended. This feature is used to 
hold a child restraint system (CRS) firmly. To 
free the belt again, fu lly retract the belt and 
then pull the belt out once more. ( P.40)
When fastening a front seat belt, 
ensure that it is passed through the seat 
belt guide. Passing the seat belt 
through the guide enables the seat belt 
to be easily extended.
When you get into or ou t of the rear seats, 
release the seat belt from the seat belt 
guide.
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.

WARNING
■When using the seat belt guide
●Always make sure that the belt is not 
twisted, and runs freely through the 
guide.
●Regardless of whether the guide is 
used or not, always secure the seat belt 
guide button.
●Do not hang from or pull the guide 
forcefully.
