●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touching a key to the security system (key with
a built-in transponder chip) of another vehicle

system from starting if the key has not been previously registered in the
vehicle's on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.

RX400h_U
Airbag system componentsYour 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
airbag system is controlled by the airbag sensor assembly. The airbag
sensor assembly consists of a sa fing sensor and an airbag sensor.

Before driving
RX400h_UIn 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.
■SRS 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, front pas-
senger occupant classification system, AIR BAG ON indicator light, AIR BAG
OFF indicator light, front passenger's seat belt buckle switch, front seat belt
pretensioner assemblies, inflators, interconnecting wiring and power sources.
(
→ P. 3 8 9 )
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well
as the front seats, and parts of the front pillar and roof side rail, may be hot for sev-
eral minutes. The airbag itself may also be hot.
●The front windshield may crack.
■Operating conditions (front airbags)
●The 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) colli-
sion 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.).
●It is possible that in some collisions where the forward deceleration of the vehicle
is very close to the designed threshold level, the SRS front airbags and the seat
belt pretensioners may not activate together.
