WARNING
■When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to chokin g or other serious injuries that could result
in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut the
belt.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Shake the child restraint system left and right, and forward and backward to ensure
that it has been securely installed.
●After securing a child restraint system, never adjust the seat.
●When a booster seat is installed, always ensure that the shoulder belt is positioned
across the center of the child’s shoulder. The belt should be kept away from the child’s
neck, but not so that it could fall off the child’s shoulder.
●Follow all installation instructions provided by the child restraint system manufacturer.
●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.
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only. This could cause injury or discomfort to
the child. ( P. 34)
■Do not use a seat belt extender
If a seat belt extender is used when insta lling a child restraint system, the seat belt will
not securely hold the child restraint system , which could cause death or serious injury
to the child or other passengers in the event of sudden braking, sudden swerving or an
accident.

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.

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.

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.
