After installing the child restraint system, rock it back and forth to ensure
that it is installed securely. (P. 70)
■When installing in the rear center seat
There are no LATCH anchors behind th e rear center seat. However, the
inboard LATCH anchors of the outboard seats, which are 18.1 in. (460 mm)
apart, can be used if the child restraint system manufacturer’s instructions per-
mit use of those anchors with the anchor spacing stated.
Child restraint systems with rigid lower attachments cannot be installed in the
center seat. This type of child restraint system can only be installed in the out-
board seat.
■Laws and regulations pertaining to anchors
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMV SS213 or CMVSS213 specifications can be
used.
This vehicle is designed to conform to SAE J1819.
WARNING
■When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
●When using the LATCH anchors, be sure that there are no foreign objects around the
anchors and that the seat belt is not caught behind the child restraint system.
●Follow all installation instructions provided by the child restraint system manufacturer.
●Never attach two child restraint system attachments to the same anchor. In a collision,
one anchor may not be strong enough to hold two child restraint system attachments
and may break.
If the LATCH anchors are already in use, use the seat belt to install a child restraint
system in the center seat.
●When securing some types of child restraint systems in rear seats, it may not be possi-
ble to properly use the seat belts in positions next to the child restraint without inter-
fering with it or affecting seat belt effectiveness. Be sure your seat belt fits snugly
across your shoulder and low on your hips. If it does not, or if it interferes with the child
restraint, move to a different position. Failure to do so ma y result in death or serious
injury.
●When installing a child restraint system in th e rear center seat, adjust both seat cush-
ions to the same position an d align both seatbacks at the same angle. The seatbacks
must be adjusted to the same angle. Otherwise, the child restra int system cannot be
securely restrained and this may cause death or serious injuries in the event of sudden
braking, sudden swerving or an accident.
●If the seat is adjusted, reconfirm the security of the child restraint system.

■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to move with
the “READY” indicator is illuminated. For safety, make sure to shift the shift lever to P and
apply the parking brake when parked.
The following sounds or vibrations may occu r when the hybrid system is operating and
are not a malfunction:
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid system starts or stops.
●Relay operating sounds such as a snap or so ft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear se ats, when the hybrid system is started or
stopped.
●Sounds from the hybrid system may be heard when the back door is open.
●Sounds may be heard from the transmission wh en the gasoline engine starts or stops,
when driving at low spee ds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is depressed
or as the accelerator pedal is released.
●Vibration may be felt when the ga soline engine starts or stops.
●Cooling fan sounds may be heard from th e air intake vents under the rear seats.
■Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be difficult for sur-
rounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of the vehicle, it
may be more difficult to hear from the re ar of the vehicle compared to the front.
■Maintenance, repair, recycling, and disposal
Contact your Lexus dealer regarding mainte nance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.

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. 538)
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 vehicles 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 li mited service life. The lifespan of the hybrid
battery (traction battery) can change in acco rdance with driving style and driving condi-
tions.
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC sy stems 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 starting as the system uses high voltage. Be
careful of both the high voltage and the high temperature, and always obey the warn-
ing labels attached to the vehicle.
●Never try to open the service plug accesshole located under the rear seat. The service
plug is used only when the vehicle is serviced
and is subject to high voltage.
