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. ●

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. ●

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

essary. The seat belt is most effective
when the occupants are sitting up
straight and well ba ck in the seats.
●

 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)

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.
