WARNING
■General precautions while driving
Driving under the infl uence: Never drive
your vehicle when un der the influence of
alcohol or drugs that have impaired your
ability to operate your vehicle. Alcohol
and certain drugs delay reaction time,
impair judgment and reduce coordina-
tion, which could lead to an accident that
could result in death or serious injury.
Defensive driving: Always drive defen-
sively. Anticipate mistakes that other
drivers or pedestrians might make and
be ready to avoid accidents.
Driver distraction: Always give your full
attention to driving. Anything that dis-
tracts the driver, such as adjusting con-
trols, talking on a cellular phone or
reading can result in a collision with
resulting death or serious injury to you,
your occupants or others.
■General precaution regarding chil-
dren’s safety
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof, or other features of the
vehicle. In addition, heat build-up or
extremely cold temperatures inside the
vehicle can be fatal to children.

WARNING
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 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
continue driving and take a break
immediately.

WARNING
Observe the following precautions to
reduce the risk of in jury 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 ba ck in the seats.
●Do not wear the shoulder belt under
your arm.
●Always wear your seat belt low and
snug across your hips.

For safety and security
 Extend the shoulder belt so that it
comes fully over the shoulder, but
does not come into contact with the
neck or slide off the shoulder.
 Position the lap belt as low as possi-
ble over the hips.
 Adjust the position of the seatback.
Sit up straight and well back in the
seat.
 Do not twist the seat belt.
WARNING
■Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. ( P.27)
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.27)
■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, scis-
sors 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.
●Inspect the seat belt system periodi-
cally. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt
until it is replaced. Damaged seat belts
cannot protect an occupant from
death or serious injury.
●Ensure that the belt and plate are
locked and the belt is not twisted.
If the seat belt does not function cor-
rectly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including
the belts, if your vehicle has been
involved in a seriou s accident, even if
there’s no obvious damage.
●Do not attempt to install, remove,
modify, disassemble or dispose of the
seat belts. Have any necessary repairs
carried out by your Lexus dealer. Inap-
propriate handling may lead to incor-
rect operation.

pally designed for persons of adult size.

●When the child becomes large enough to
properly wear the vehicle’s seat belt, fol-
low the instructions regarding seat belt
usage. ( P.26)

WARNING
■Using a seat belt extender
Observe the following precautions to
reduce the risk of injury in the event of
sudden braking, sudd en swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
●Do not wear the seat belt extender if
you can fasten the seat belt without the
extender.
●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 vehi cle, when used by
another person, or at a different seat-
ing position other than the one origi-
nally intended.
NOTICE

The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi- cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.
■Replacing the belt after the preten-
sioner has been activated
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.

WARNING
■Adjustable shoulder anchor
Always make sure th e 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.

WARNING
Observe the following precautions to
reduce the risk of in jury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
■Seat belt pretensioners
●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.
