Vehicle data recordings
Your Lexus is equipped with several sophisticated computers that will record cer-
tain 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 with
which it is equipped. 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 use by Lexus in a law suit
• 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 information on data collected and its usage.

Event data recorder
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
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.

When driving
IS250C/350C_U
■Starting off on a hill
Hill-start assist control will operate. (→P. 2 2 0 )
■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 down-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
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake sys-
tem needs bedding-down of the brake shoes periodically or whenever the parking
brake shoes and/or drum are replaced. Have your Lexus dealer perform the bed-
ding down.
