Before driving

High voltage components*: With AWD models only
Take care when handling the hybrid system, as it contains a high voltage
system (about 650V at maximum) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle. Air conditioning compressor

RX400h_U■
Hybrid battery air vent
There is an air intake vent under
the rear seats to cooling the hybrid
battery (traction battery). If the
vent becomes blocked, the hybrid
battery may overheat, leading to a
reduction in hybrid battery output.
Emergency shut off system
The emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the r isk of electrocution and fuel leakage
when a certain level of impact is detected by the impact sensor. If the
emergency shut off system activates, your vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.
Energy monitor/consumption screen
You can view the status of your hybr id system on the multi-information
display ( →P. 143) and the navigation system screen. The following
images are examples only, and may vary slightly from actual conditions.
■ Energy monitor
● How to display on the navigation system screen:
Press INFO.
Touch on the Information screen.
If the Consumption screen is displayed, touch .
● How to display on the multi-information display:
Push the button several times to select the energy moni-
tor display.

1-8. Safety information

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.

1-8. Safety information
RX400h_U
●The 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 lug-
gage is put in the seat, or the seat belt is fastened, even if the seat is unoccupied.
(→ P. 1 0 3 )
■Operating conditions (side airbags)
●The SRS side airbags are designed to inflate when the passenger compartment is
subjected to a severe impact from the side.
●The SRS side airbag on the passenger seat will not activate if there is no passen-
ger sitting in the front passenger seat. However, the side airbag on the passenger
seat may deploy if luggage is put in the seat, or the seat belt is fastened, even if the
seat is unoccupied. ( →P. 1 0 3 )
■Operating conditions (curtain shield airbags)
The SRS curtain shield airbags are designed to inflate when the passenger com-
partment is subjected to a severe impact from the side or vehicle rollover.
■Conditions under which the SRS airbags ma y deploy (inflate), other than a colli-
sion
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situations shown in the
illustration.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
●The angle of vehicle tip-up is marginal.
●The vehicle skids and hits a curb stone.
