There 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 not recognize him/her as an adult depending on
his/her physique and posture.
* 2
: In the event the front passenger is wearing a seat belt.
* 3
: In the event the front passenger does not wear a seat belt.
* 4
: For some children, child in se at, child in booster seat or child in convertible seat, the
system may not recognize him/her as a child. Factors which may affect this can be the
physique or posture.
* 5
: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint system should on ly be installed on the front passenger seat
when it is unavoidable. (  P. 5 9 )
* 6
: In case the indicator light is not illuminated, consult this manual on how to install the
child restraint system properly. (  P. 6 1 )Indicator/

Front passenger occupant classification system precautions ●
Do not recline the front passenger seatback so far that it touches a rear seat. This may
cause the “AIR BAG OFF” indicator light to be illuminated, whic h indicates that the
SRS airbags for the front passenger will not activate in the event of a severe accident.
If the seatback touches the rear seat, return the seatback to a position where it does
not touch the rear seat. Keep the front pa ssenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the effec-
tiveness of the seat belt system. ●
If an adult sits in the front passenger seat , the “AIR BAG ON” indicator light is illumi-
nated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit up
straight, well back in the seat, feet on the floor, and with the seat belt worn correctly. If
the “AIR BAG OFF” indicator still remains illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front passenger seat fully
rearward. ●
When it is unavoidable to install a forward- facing child restraint system on the front
passenger seat, install the child restraint sy stem on the front passenger seat in the
proper order. (  P. 6 1 )●
Do not modify or remove the front seats. ●
Do not kick the front passenger seat or subj ect it to severe impact. Otherwise, the
SRS warning light may come on to indicat e a malfunction of the front passenger
occupant classification system. In this ca se, contact your Lexus dealer immediately.●
Child restraint systems installed on the rear seat should not contact the front seat-
backs. ●
Do not use a seat accessory, such as a cu shion and seat cover, that covers the seat
cushion surface. ●
Do not modify or replace the upholstery of the front seat.

wear the vehicle’s seat belt. ●
Choose a child restraint system that suits your vehicle and is appropriate to
the age and size of the child.Child restraint systems Before installing a child restraint system in the vehicle, there are precautions
that need to be observed, different type s of child restraint systems, as well as
installation methods, etc., written in this manual.

RX450h_U_OM0E013U The illustration is an example for explanation and may differ from the actual item.
* : AWD models onlyHybrid system precautions Take care when handling the hybrid system, as it is a high voltage system
(about 650 V at maximum) as well as contains parts that become extremely
hot when the hybrid system is operating. Obey the warning labels attached to
the vehicle.

For safety and security
RX450h_U_OM0E013U The air intake/discharge vents for the
hybrid battery (traction battery) are
located under the rear seats and in lug-
gage compartment respectively. If the
air intake vents are blocked, it could
lead to a reduction in hybrid battery
(traction battery) output.
When a certain level of impact is detected by the impact sensor, the emergency
shut off system blocks the high voltage current and stops the fuel pump to mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle will not restart. To restart the hybrid system, contact your
Lexus dealer.
A message is automatically displayed when a malfunction occurs in the hybrid
system or an improper operation is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.

If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this case, try to start the system again. If the “READY”
indicator does not come on, contact your Lexus dealer. ■
Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light (  P. 5 3 8 )
go off. If there is only a small amount of fu el, the hybrid system may not be able to start.
(The standard amount of fuel is about 2.9 gal. [11.0 L, 2.4 Imp.gal.], when the vehicle is on
a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when
the vehicle is inclined.) ■
Electromagnetic waves ●
High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as
conventional gasoline powered vehicl es or home electronic appliances.●
Your vehicle may cause sound interference in some third party-produced radio parts.■
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi-
tions.
WA R N I N G ■
High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt system. DC and
AC high voltage is very dangerous and can cause severe burns and electric shock that
may result in death or serious injury. ●
Never touch, disassemble, remove or replace the high voltage parts, cables or their
connectors. ●
The hybrid system will become hot after star ting as the system uses high voltage. Be
careful of both the high voltage and the hi gh temperature, and always obey the warn-
ing labels attached to the vehicle. ●
Never try to open the service plug access
hole located under the rear seat. The service
plug is used only when the vehicle is serviced
and is subject to high voltage.
