For your information

Main Owner’s Manual

Please note that this manual applies to all models and explains all equipment, includ­ing 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. How­ever, 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 evapo­ration 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 perfor­mance problems resulting from the modification may not be covered under war­ranty.

22

Installation of a mobile two-way radio system

The installation of a mobile two-way radio system in your vehicle could affect elec­tronic systems such as:

● Hybrid system

● Multiport fuel injection system/sequential multiport fuel injection system

● Cruise control system

● Dynamic radar 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.

23

Vehicle control and operation data recording

Your Lexus is equipped with sophisticated computers that record certain informa­tion about your vehicle’s operation, such as:

•Engine speed

• Motor speed

• Accelerator status

•Brake status

• Vehicle speed

•Shift position
The data recorded varies according to the grade level and options the vehicle is
equipped with. The computers do not record conversations, sound or pictures.

● Data usage

Lexus may use the data recorded in these computers to diagnose malfunctions,
conduct research and development, and improve quality.

Lexus will not disclose the recorded data to a third party except:

• With the consent of the vehicle owner or with the consent of the lessee if the
vehicle is leased

• In response to an official request by the police, a court of law or a government
agency

• For research purposes where the data is not tied to a specific vehicle or vehicle
owner

24

● Event data recorder

Your vehicle has computers that monitor and control certain aspects of your vehi­cle. These computers assist in driving and maintaining optimal vehicle performance.

Besides storing data useful for troubleshooting, there is an event data recorder
(EDR) that records data in a crash or near crash event.

The SRS airbag sensor assembly contains the EDR. In a crash or near crash event,
this device may record the following information:

•Engine speed

• Whether the brake pedal was applied or not

•Vehicle speed

• To what extent the accelerator pedal was depressed

• Position of the transmission shift lever

• Whether the driver and front passenger wore seat belts or not

• Driver’s seat position

• SRS airbag deployment data

• SRS airbag system diagnostic data

• Front passenger’s occupant classification
The information above is intended to be used for the purpose of improving vehicle

safety performance. Unlike general data recorders, the EDR does not record sound
data such as conversation between passengers.

● Disclosure of the EDR data

Lexus will not disclose the data recorded in an EDR to a third party except when:

• An agreement from the vehicle’s owner (or the leasing company for a leased

vehicle) is obtained

• Officially requested to by the police or other authorities

• Necessary, for use as a defense for Lexus in a lawsuit

• Ordered to by a court of law
However, if necessary, Lexus will:

• Use the data for research on Lexus vehicle safety performance

• Disclose the data to a third party for research purposes without disclosing details

of the vehicle owner, and that only when deemed necessary

• Disclose summarized data cleared of vehicle identification information to a non-

Lexus organization for research purposes

25

● Lexus Safety Connect /Lexus Enform (U.S. mainland only)

CAUTION

If your Lexus has Safety Connect or Lexus Enform and if you have subscribed to
those services, please refer to the Safety Connect /Lexus Enform Telematics Sub­scription Service Agreement for information on data collected and its usage.

■ General precautions while driving

Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol
and certain drugs delay reaction time, impair judgment and reduce coordination,
which could lead to an accident that could result in death or serious injury.

Defensive driving: Always drive defensively. Anticipate mistakes that other drivers
or pedestrians might make and be ready to avoid accidents.

Driver distraction: Always give your full attention to driving. Anything that distracts
the driver, such as adjusting controls, talking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.

■ General precaution regarding children’s safety

Never leave children unattended in the vehicle, and never allow children to have or
use the key.

Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the windows, the
moon roof, or other features of the vehicle. In addition, heat build-up or extremely
cold temperatures inside the vehicle can be fatal to children.

26

CAUTION

■ Disposal of the hybrid battery (traction battery)

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 battery is not disposed of properly, it may cause electric shock that can result
in death or serious injury.

1-1. Hybrid system

Your vehicle is a hybrid vehicle. It has characteristics different from con­ventional 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 effi­ciency and reducing exhaust emissions.
