IS350/250_U (OM53C50U)Your Lexus is 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 with which it is
equipped. Furthermore, these computers do not record conversations, sounds or pic-
tures.
●Data usage
Lexus may use the data recorded in these computers to diagnose malfunctions, con-
duct 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 Co nnect / 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 Subscription
Service Agreement for information on data collected and its usage.

IS350/250_U (OM53C50U)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.

CAUTION
■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 coul d 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 atte ntion 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 tem-
peratures inside the vehicle can be fatal to children.

■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 hub, airbag cover and inflator) as well as the
seats, parts of the front and rear pillars, and roof side rails may be hot for several min-
utes. The airbag itself may also be hot.
●The windshield may crack.
●For Lexus Enform 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 communi-
cate, the agent automatically treats the call as an emergency and helps to dispatch the
necessary emergency services. (→ P. 3 9 0 )
CAUTION
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airbags may malfunction or deploy (inflate)
accidentally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, fr ont, side and rear pillars or roof side rails

compartment

IS350/250_U (OM53C50U)4-6. Driving tips
●Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
•Washer fluid
●Have a service technician inspect the condition of the battery.
●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 brand, and that chains match the size
of the tires.
*: Tire chains cannot be mounted on the 18-inch tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately 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.
●Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the vehicle
ahead, and drive at a reduced speed suitable to road conditions.
Winter driving tips

■Reception sensitivity
●Maintaining perfect radio reception at all times is difficult due to the continually chang-
ing position of the antenna, differences in signal strength and surrounding objects, such
as trains, transmitters, etc.
●The radio antenna is mounted inside the rear window. To maintain clear radio reception,
do not attach metallic window tinting or other metallic objects to the antenna wire
mounted inside the rear window.
