For your information
Main Owner’s Manual
Please note that this manual applies to all models and explains all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not installed
on y
our vehicle.
All specifications provided in this manual are current at the time of printing. How -
ever, because of the Lexus policy of contin ua
l product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle show n in
the illustration may differ from
your vehicle in terms of color and equipment.
Accessories, spare parts and modification of your Lexus
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are
currently available in the market. You should know that Toyota does not warrant
these products and is not responsible for their performance, repair, or replacement,
or for any damage they may cause to, or adverse effect they may have on, your
Lexus vehicle.
This vehicle should not be modified with non-genuine Lexus products. Modification
with

non-genuine Lexus products could affect its performance, safety or durability,
and may even violate governmental regula tions. In addition, damage or perfor-
mance problems resulting from the modi fication may not be
covered under war-
ranty.
Installation of a mobile two-way radio system
As the installation of a mobile two-way ra dio 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 hybr i
d 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.

xvii
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 deal er before you scrap your vehicle.
Smart access system with push-button start
Users of any electrical medical devices such as implanted pacemakers should con -
sult the manufacturer of the device for information about its operation under the
influence
of radio waves. Radio waves could have unexpected effects on the opera -
tion of such me dical de
vices. (P. 1 2 , 14 )
Leak detection pump (for the U.S.A. and Canada)
This pump performs fuel evaporation leakage check. This check is conducted sev -
eral hours after the hybrid system is turn ed of
f. You may hear a sound coming from
underneath the trunk for several minutes, however this does not indicate a malfunc-
tion.

1-1. Hybrid system
Hybrid system
Your vehicle is a hybrid vehicle. It has characteristics different from con-
ventional vehicles. Be sure you are clos ely familiar
with the characteristics
of your vehicle, and operate with care.
The hybrid system combines a gasoline e
ngine and an electric motor (trac-
tion motor) according to driving conditions, improving fuel efficiency and
r
educing exhaust emissions.
Gasoline engine
Electric motor (Traction motor)
■ When stopped/
during take-off
The gasoline engine stops when the v
ehicle is stopped. During take-
off, the electric motor (traction motor) drives the vehicle. At slow
speeds or when traveling down a ge ntle slope, the engine is stopped
and the motor is used.

1-1. Hybrid system
■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
block
ed, 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 el ectrocution and fuel leakage
when a certain level of impact is detected by the impact sensor. If the
emergency shut off system activates, yo ur vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.
Energy monitor/consumption screen
You can view the status of your h ybrid system on the multi-information
display ( P. 117) and the touch screen( P. 1 8 2 ). The following images
