Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classifica-
tion system.
Failure to do so may cause death or serious injury. ●
Wear the seat belt properly. ●
Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat. ●
Make sure the “AIR BAG OFF” indicator li ght is not illuminated when using the seat
belt extender for the front passenger seat. If the “AIR BAG OFF” indicator light is illu-
minated, disconnect the extender tongue from the seat belt buckle, and reconnect
the seat belt. Reconnect the seat belt extender after making sure the “AIR BAG ON”
indicator light is illuminated. If you use th e seat belt extender while the “AIR BAG
OFF” indicator light is illumi nated, the SRS airbags for the front passenger will not
activate, which could cause death or serious injury in the event of a collision.●
Do not apply a heavy load to the front pa ssenger seat or equipment (e.g. seatback
pocket). ●
Do not put weight on the front passenger se at by putting your hands or feet on the
front passenger seat seatback from the rear passenger seat.●
Do not let a rear passenger lift the front passenger seat with their feet or press on the
seatback with their legs. ●
Do not put objects under the front passenger seat.

NX300h_U_OM78007USafety information for children ●
It is recommended that children sit in the rear seats to avoid accidental con-
tact with the shift lever, wiper switch, etc. ●
Use the rear door child-protector lock or the window lock switch to avoid
children opening the door while driving or operating the power window acci-
dentally. (  P. 126, 166)●
Do not let small children operate equi pment which may catch or pinch body
parts, such as the power window, hood, back door, seats etc.Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriate for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt.
WA R N I N G
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 sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon roof

When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.●
For effective protection in automobile a ccidents and sudden stops, a child must be
properly restrained, using a se at belt or child restraint system depending on the age
and size of the child. ●
Lexus strongly urges the use of a proper child restraint system that conforms to the
size of the child, installed on the rear seat . According to accident statistics, the child is
safer when properly restrained in th e rear seat than in the front seat.●
Holding a child in your or someone else’s ar ms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield or between
the holder and the interior of the vehicle. ●
Place one child to a child restraint system and then secure the child with the harness
of the child restraint system. ■
Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of sudden braking, sudden swerv-
ing, or an accident. ●
If the vehicle were to receive a strong impact from an accident, etc., it is possible that
the child restraint system has damage that is not readily visible. In such cases, do not
reuse the restraint system. ●
Make sure you have complied with all installa tion instructions prov ided with the child
restraint system manufacturer and that the system is properly secured. ●
Keep the child restraint system properly secured on the seat even if it is not in use. Do
not store the child restraint system unsecured in the passenger compartment. ●
If it is necessary to detach the child rest raint system, remove it from the vehicle or
store it securely in the luggage compartment.
