Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus dealer before you scrap your vehicle.
CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired you ability to operate your vehicle. Alcohol and
certain drugs delay reaction time, impair judgment and reduce coordination, which
could lead to an accident that will hurt or kill you, your occupants or others.
Defensive driving: Always drive defensively. 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 distracts
the driver, such as adjusting controls, 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 children’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 cigarette
lighter, 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.

1-2. Opening, closing and locking the doors and trunk
■Impact detection door lock release system
In the event that the vehicle is subject to a strong impact, all the doors are unlocked.
Depending on the force of the impact or the type of accident, however, the system
may not operate.
■Using the mechanical key
The doors can also be locked and unlocked with the mechanical key. (P. 3 6 9 )
■Customization
Settings (e.g. unlocking function using a key) can be changed. (P. 406)
CAUTION
■To prevent an accident
Observe the following precautions while driving the vehicle.
Failing to do so may result in a door opening and an occupant falling out, resulting in
death or serious injury.
●Always use a seat belt.
●Always lock all doors.
●Ensure that all doors are properly closed.
●Do not pull the inside handle of the front door while driving.
●Set the rear door child protector locks when children are seated in the rear seat.

Before driving
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way.
■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
●Use a child restraint system appropriate for the child, until the child become
large enough to properly wear the vehicle's seat belt. (P. 7 7 )
●When the child becomes large enough to properly wear the vehicle's seat belt,
follow the instructions on P. 34 regarding seat belt usage.
■Replacing the belt after the pretensioner has been activated
The seat belts cannot be used after a pretensioner has been activated. After an
accident, have your Lexus dealer inspect the pretensioners. Make sure the preten-
sioners are replaced if they have been activated.
■Seat belt extender
If your seat belts cannot be fastened securely
because they are not long enough, a person-
alized seat belt extender is available from
your Lexus dealer free of charge.

CAUTION
■Wearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of sud-
den braking or an accident.
Failing to do so may cause death or severe injury.
●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, including children.
●Lexus recommends that children be seated in the rear seat and always use a seat
belt and/or an appropriate child restraint system.
●Do not recline the seat any more than necessary to achieve a proper seating
position. 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.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. 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 tab are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in
a serious 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. Inappropriate han-
dling of the pretensioner may prevent it from operating properly resulting in
death or serious injury.

CAUTION
■Using a seat belt extender
●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 injury in the event of a collision.
●The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seating position other than the one originally
intended.
NOTICE
■When using a seat belt extender
When releasing the seat 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.

1-7. Safety information
CAUTION
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. An infant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats are the safest for infants and children.
(P. 7 7 )
●If the seat belt extender has been con-
nected to the driver's seat belt buckle but
the seat belt extender has not also been
fastened to the latch plate of the driver's
seat belt, the SRS driver's airbag system
will judge that the driver is wearing the seat
belt even though the seat belt has not been
connected. In this case, the driver's airbag
may not activate correctly in a collision,
resulting in death or serious injury in the
event of collision. Be sure to wear the seat
belt with the seat belt extender.

CAUTION
■SRS airbag precautions
●Do not sit on the edge of the seat or lean
against the dashboard.
●Do not allow a child to sit on the knees of a
front passenger while the vehicle is moving.
●Do not drive the vehicle while the driver or
passenger have items resting on their
knees.
●Do not lean against the door, the roof side
rail or the front, side and rear pillars.
●Do not allow anyone to kneel on the pas-
senger seat toward the door or put their
head or hands outside the vehicle.
