Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as the hybrid system, multiport fuel injection system/
sequential multiport fuel injection system, dynamic radar cruise control system,
cruise control system, anti-lock brake system, vehicle dynamics integrated manage-
ment, SRS airbag system and seat belt pretensioner system, be sure to check with
your Lexus dealer for precautionary measures or special instructions regarding
installation.
High voltage parts and cables on the hybrid vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.

■Regenerative braking
The motor generator converts kinetic energy to electric energy when:
●The accelerator pedal is released.
●The brake pedal is depressed with the shift lever in “D” or “S”.
■When stopped/during take-off
The gasoline engine stops when the vehicle is stopped. During take-
off, the electric motor (traction motor) drives the vehicle. At slow
speeds or when traveling down a gentle slope, the engine is stopped
and the motor is used.
■ During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid battery as necessary.
■ When accelerating sharply
The power of the hybrid battery (traction battery) is added via elec-
tric motor (traction motor) to that of the gasoline engine.
■ When braking (Regenerative brake)
The electric motor (traction motor) charges the hybrid battery
(traction battery).

■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to
move. Always put the shift lever in “P” when parked.
The following sounds or vibrations may occur 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
seat when the hybrid system starts or stops.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transmission when the hybrid system starts or
stops.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard from the regenerative brake when you press the brake
pedal.
●Vibration may be felt when the gasoline engine starts or stops.
●You may hear cooling fan sounds coming from the air intake vents behind the
rear seat.
■Maintenance, repair, recycling, and disposal
Contact your Lexus dealer regarding maintenance, repair, recycling and disposal.
Do not dispose of the vehicle yourself.

CAUTION
■Road accident cautions
Observe the following precautions to reduce the risk of injury.
●Pull your vehicle off the road, put the shift lever in “P”, apply the parking brake,
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 it 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 electric fires. Using even a small
amount of water may be dangerous.
●If your vehicle needs to be towed, do so with the rear wheels raised. If the wheels
with the electric motor (traction motor) are on the ground when towing, the
motor may continue to generate electricity. This may cause an electricity leakage
leading to a fire. (
→P. 5 0 1 )
●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.
