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 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.
■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, scissors should be used to cut
the belt.
■Seat belt pretensioners
●Do not place anything, such as a cushion, 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 pretensioner for the
front passenger's seat may not activate in the event of a collision.
●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.

1-4. Opening and closing the windows and moon roof
IS F_U
■The moon roof can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
■Moon roof open warning buzzer
The buzzer sounds and a message is shown on the multi-information display in the
instrument panel when the “ENGINE START STOP” switch is turned OFF and the
driver's door is opened with the moon roof open.
■Door lock linked moon roof operation
The moon roof can be opened and closed using the mechanical key. (→P. 5 0 5 )
■Operating the moon roof after turning the “ENGINE START STOP” switch OFF
The moon roof can be operated for approximately 45 seconds even after the
“ENGINE START STOP” switch is switched to ACCESSORY mode or turned
OFF. It cannot, however, be operated once either front door is opened.
■Jam protection function
If an object is detected between the moon roof and the frame while closing or tilting
down, travel is stopped and the moon roof opens slightly.
■To reduce moon roof wind noise
Drive with the moon roof opened to slightly before the fully open position as driving
with the moon roof opened fully will cause wind noise.
■Sunshade
The sunshade can be opened and closed manually. However, the sunshade will
open automatically when the moon roof is opened.
