WARNING
■When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Firmly attach the top tether strap and make sure that the belt is not twisted.
●Do not attach the top tether strap to anything other than the anchor bracket.
●Follow all installation instructions provided by the child restraint system manufacturer.
●When installing the child restraint system with the head restraint being raised, after
the head restraint has been raised and then the anchor bracket has been fixed, do not
lower the head restraint.
●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.
NOTICE
■Anchor brackets (for top tether strap)
When not in use, make certain to close the lid. If it remains open, the lid may be dam-
aged.

Hybrid 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. 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.

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Pull your vehicle off the road, shift the shift lever to P, apply the parking brake, and
turn the hybrid system off.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
●If a fluid leak occurs, do not touch the flui d as it may be strong alkaline electrolyte
from the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or, if possible, boric acid
solution. Seek immedi ate medical attention.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never use a
fire extinguisher that is not meant for el ectric fires. Using even a small amount of
water may be dangerous.
●If your vehicle needs to be towed, do so with front wheels (2WD models) or four
wheels (AWD models) raised. If the wheels connected to the electric motor (traction
motor) are on the ground when towing, the motor may continue to generate electric-
ity. This may cause a fire. ( P. 530)
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto
the ground, the fuel system may have been damaged. Leave the vehicle as soon as
possible.

WARNING
■Hybrid battery (traction battery)
●Never resell, hand over or modify the hybrid battery. To prevent accidents, hybrid
batteries that have been removed from a disposed vehicle are collected through
Lexus dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting in death
or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is hazardous to
the environment or someone may touch a high voltage part, resulting in an electric
shock.
• The hybrid battery is intended to be used exclusively with your hybrid vehicle. If the hybrid battery is used outside of your vehicle or modified in any way, accidents
such as electric shock, heat generation , smoke generation, an explosion and elec-
trolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident is
extremely high because the person receiving the vehicle may not be aware of these
dangers.
●If your vehicle is disposed of without the hybrid battery having been removed, there is
a danger of serious electric shock if high voltage parts, cables and their connectors
are touched. In the event that your vehicle must be disposed of, the hybrid battery
must be disposed of by your Lexus dealer or a qualified service shop. If the hybrid bat-
tery is not disposed of properly, it may cause electric shock that can result in death or
serious injury.
NOTICE
■Hybrid battery (traction battery) air intake/discharge vents
●Do not place objects that will block the air intake vents. The hybrid battery (traction
battery) may overheat and be damaged.
●Clean the air intake/discharge vents regularl y to prevent the hybrid battery (traction
battery) from overheating.
●Do not get water or foreign materials in either the air intake/discharge vents as this
may cause a short circuit and damage the hybrid battery (traction battery).
●Do not carry large amounts of water such as water cooler bottles in the vehicle. If
water spills onto the hybrid battery (tract ion battery), the battery may be damaged.
Have the vehicle inspected by your Lexus dealer.
