IS250_EE(OM53C51E)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 any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional before you scrap your vehicle.
Scrapping of your Lexus
Your vehicle contains batteries and/or accumulators. Do not discard them into the
environment but cooperate with separate collection (Directive 2006/66/EC).
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 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, heat build-up or extremely cold tem-
peratures inside the vehicle can be fatal to children.

IS250_EE(OM53C51E)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
Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.
