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
●Dynamic radar cruise control system
●Cruise control system
●Anti-lock brake system
●Vehicle dynamics integrated management
●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.
Your Lexus equipped with several sophisticated computers that will record certain
data, such as: •Engine speed
• Accelerator status
•Brake status
• Vehicle speed
• Shift position
The recorded data varies according to the vehicle grade level and options equipped
with. Furthermore, these computers do not record conversations, sounds 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
● Usage of data collected through Safety Connect / Lexus Enform (U.S. mainland
only)
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 Sub-
scription Service Agreement for informat ion on data collected and its usage.

Vehicle data recording

10
GS350_U (OM30C34U)
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 desi gned to record data related to vehicle
dynamics and safety systems for a short peri od 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 passenge r 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 unde rstanding 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 ac quired during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access to the
vehicle 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 re search purposes without disclosing infor-
mation about the specific vehicle or vehicle owner

Gently depress the accelerator pedal.
Release the parking brake.
■When starting off on a uphill
The hill-start assist control is available. (P. 2 76 )
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because there
may be a layer of water between the tires and the road surface, preventing the
steering and brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is
due to automatic up-shifting control or do wn-shifting implementation to meet driv-
ing conditions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
