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.

●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 law suit
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 infor- mation about the specific vehicle or vehicle owner
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.

1-7. Safety information
IS250C/350C_U
■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side airbag sensor assemblies, driver's seat position sensor, driver's seat belt buckle
switch, front passenger occupant classification system (ECU and sensors), “AIR
BAG ON” indicator light, “AIR BAG OFF” indicator light, front passenger’s seat
belt buckle switch, seat belt pretensioner assemblies, airbags, interconnecting wir-
ing and power sources. (→P. 4 9 2 )
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel, airbag cover and inflator) as well as
the front seats may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Safety Connect subscribers, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency call to
the response center, notifying them of the vehicle’s location (without needing to
push the “SOS” button) and an agent will attempt to speak with the occupants
to ascertain the level of emergency and assistance required. If the occupants
are unable to communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. ( →P. 388)
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 12 -
18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).

When driving
IS250C/350C_U
Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear tires.
Ensure that all tires are the specified size and the same brand, and that
chains match the size of the tires.
■ Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Remove any ice that has accumulated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow that
may have accumulated in the wheel well or on the brakes.
