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.

rently available in the market. You should know that Toyota does not warrant these prod-

ucts 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.

The vehicle is equipped with sophisticated computers that will record certain data, such

as: The recorded data varies according to the vehicle grade level and options with which

it is equipped. These computers do not record conversations or sounds, and only record

images outside of the vehicle in certain situations.

• Engine speed/Electric motor speed (traction motor speed)

• Accelerator status

• Brake status

• Vehicle speed

• Operation status of the driving assist systems, such as the ABS and pre-collision sys-

tem

● Data transmission

Your vehicle may transmit the data recorded in these computers to Lexus without noti-

fication to you.

● Data usage

Lexus may use the data recorded in this computer 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 use by Lexus in a lawsuit

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

owner

● To learn more about the vehicle data collected, used and shared by Lexus, please visit

Vehicle data recording

Usage of data collected through Lexus Enform (U.S. mainland only)

This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR

is to record, in certain crash or near crash-like situations, such as an air bag deployment

or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems

performed. The EDR is designed to record data related to vehicle dynamics and safety

systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:

• How various systems in your vehicle were operating;

• Whether or not the driver and passenger safety belts were buckled/fastened;

• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,

• How fast the vehicle was traveling.

These data can help provide a better understanding of the circumstances in which

crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a non-trivial crash situation occurs;

no data are recorded by the EDR under normal driving conditions and no personal data

(e.g., name, gender, age, and crash location) are recorded. However, other parties, such

as law enforcement, could combine the EDR data with the type of personally identifying

data routinely acquired during a crash investigation.

To read data recorded by an EDR, special equipment is required, and access to the vehi-

cle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as

law enforcement, that have the special equipment, can read the information if they have

access to the vehicle or the EDR.
● 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 lessee for a leased vehicle) is

obtained

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

agency

• For use by Lexus in a lawsuit
However, if necessary, Lexus may:
• Use the data for research on vehicle safety performance

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

tion about the specific vehicle or vehicle owner

Event data recorder

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.

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.

WARNING

■

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, temperatures inside the vehicle can be

fatal to children.
