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, cruise control system, vehicle dynamics
integrated management, SRS airbag system and seat belt pretensioner system, be
sure to check with your Lexus dealer for precautionary measures or special instruc-
tions 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.

1-1. Hybrid system
Hybrid system
Your vehicle is a hybrid vehicle. It has characteristics different from con-
ventional vehicles. Be sure you are closely familiar with the characteristics
of your vehicle, and operate with care.
The hybrid system combines a gasoline engine and an electric motor (trac-
tion motor) according to driving conditions, improving fuel efficiency and
reducing exhaust emissions.

■Hybrid battery air vent
Hybrid battery air vent
There is an air intake vent on the
package tray for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
Emergency shut off system
The emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel leakage
when a certain level of impact is detected by the impact sensor. If the
emergency shut off system activates, your vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.
Energy monitor/consumption screenYou can view the status of your hybrid system on the multi-information
display ( →P. 155) and the touch screen ( →P. 224). The following images
