For safety and security
■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 1 )
go off. If there is only a small amount of fu el, the hybrid system may not be able to start.
(The minimum amount of fuel to add to make the low fuel level warning light go out is
about 3.1 gal. [11.8 L, 2.6 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.

■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 high temperature, and always obey the cau-
tion labels attached to the vehicle.
●Never try to open the service plug access
hole located in the luggage compartment.
The service plug is used only when the vehicle
is serviced and is subject to high voltage.

■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Stop the vehicle in a safe place to prevent subsequent accidents. While depressing
the brake pedal, apply the parking brake and shift the shift position to P to stop the
hybrid system. Then, slowly release the brake pedal.
●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 fluid 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 immediate 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 raised. If the wheels con-
nected to the electric motor (traction motor) are on the ground when towing, the
motor may continue to generate electricit y. This may cause an electricity leakage
leading to a fire. ( P. 5 2 4 )
●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.
■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, th e following may occur, resulting in death
or serious injury:
• The hybrid battery may be illegally dispos ed 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 ve hicle, 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 caus e electric shock that can result in death or
serious injury.

NOTICE
■Hybrid battery air vent
●Do not put foreign objects near the air vent . The hybrid battery (traction battery) may
overheat and be damaged.
●Clean the air vent regularly to prevent the hybrid battery (traction battery) from over-
heating.
●Do not wet or allow foreign substances to enter the air vent 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 (traction battery), the battery may be damaged.
Have the vehicle inspected by your Lexus dealer.

■Triggering of the alarm
The alarm may be triggered in the following situations:
(Stopping the alarm deactivates the alarm system.)
■Alarm-operated door lock
In the following cases, depending on the si tuation, the door may automatically lock to
prevent improper entry into the vehicle:
●When a person remaining in the vehicle unlocks the door and the alarm is activated.
●While the alarm is activated, a person re maining in the vehicle unlocks the door.
●When recharging or replacing the 12-volt battery.
●A person inside the vehicle opens a door or
hood.
●The 12-volt battery is recharged or replaced
when the vehicle is locked. (P. 5 6 4 )
NOTICE
■To ensure the system operates correctly
