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 your vehicle.
All specifications provided in this manual are current at the time of printing. How-
ever, because of the Lexus policy of continual product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustrations may differ from
your vehicle in terms of color and equipment.
Noise from under vehicle after turning off the hybrid system
Approximately five hours after the hybrid system is turned off, you may hear sound
coming from under the vehicle for several minutes. This is the sound of a fuel evapo-
ration leakage check and, it does not indicate a malfunction.
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 regulations. In addition, damage or perfor-
mance problems resulting from the modification may not be covered under war-
ranty.

Installation of a mobile two-way radio system
The installation of a mobile two-way radio system in your vehicle could affect elec-
tronic systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
● Cruise control system
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Lexus dealer for precautionary measures or special
instructions regarding installation of a mobile two-way radio system.
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 the use of a gasoline engine and an electric
motor (traction motor) according to driving conditions, improving fuel effi-
ciency and reducing exhaust emissions.
Gasoline engine
Electric motor (Traction motor)
■ When stopped/during start off
The gasoline engine stops* when the vehicle is stopped. During
start 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.
When shift position N is selected, the hybrid battery (traction bat-
tery) will not be charged. Thus, select P when the vehicle is stopped.
In addition, when driving in heavy traffic, use D or B.
