Child seat belt usage
The seat belts of your vehicle are principally designed for persons of adult
size.
Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle's seat belt. (P. 121)
When the child becomes large enough to properly wear the vehicle's seat
belt, follow the instructions on P. 74 regarding seat belt usage.
Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will acti-
vate for the first collision, but will not activate for the second or subsequent
collisions.
Seat belt regulations
If seat belt regulations exist in the country where you reside, please contact
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, for seat belt replacement or installation.
CAUTION
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or severe 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, 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 seat-
ing 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.

CAUTION
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 inju-
ries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
Seat belt pretensioners
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 any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
Seat belt damage and wear
Inappropriate handling of the pretensioner may prevent it from operating
properly resulting in death or serious injury.
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 any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
