1-4. Opening and closing the windows and moon roof
nThe moon roof can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
nMoon 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.
nLinked door lock moon roof operation
lThe moon roof can be opened and closed using the mechanical key. (→P. 41 7 )
lThe moon roof can be opened using the wireless remote control. (→P. 36 )
lThe moon roof can be closed using the entry function. (→P. 25 )
nOperating 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.
nJam 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.
nWhen the moon roof does not close normally
Pressing and holding the “CLOSE” switch will close the moon roof.
nTo 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.
nSunshade
The sunshade can be opened and closed manually. However, the sunshade will
open automatically when the moon roof is opened.
nCustomization that can be configured at Lexus dealer
Settings (e.g. linked door lock operation) can be changed.

Before driving
Airbag system components
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver seat’s position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc.
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.

1-7. Safety information
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
nSRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, interconnecting wiring and power sources.
(→P. 3 8 4 )
nIf the SRS airbags deploy (inflate)
lBruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
lA loud noise and white powder will be emitted.
lParts of the airbag module (steering wheel, airbag cover and inflator) as well as
the front seats, and parts of the front pillar, rear pillar and roof side rail, may be
hot for several minutes. The airbag itself may also be hot.
lThe windshield may crack.
nOperating conditions (front airbags)
lThe SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
lIt is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
lThe SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. (→P. 9 5 )

nThere is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may recognize him/
her as a child depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a larger child who has outgrown a child restraint system sits in
the front passenger seat, the system may recognize him/her as an
adult depending on his/her physique or posture.
