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 asthey 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

WARNING
■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, whichcould 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 vehicl e, and never allow children to have or use the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselv es 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 a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this case, try to start the system again. If the “READY” indicator does not come on, contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light (P. 539) go off. If there is only a small amount of fuel, the hybrid system may not be able to start.(The standard amount of fuel is about 10 L [2.7 gal., 2.2 Imp. gal.] when the vehicle is on a
level surface. This value may vary when the vehi cle is on a slope. Add extra fuel when the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield- ing, and therefore emit approximately the same amount of electromagnetic waves as conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a lim ited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi- tions.
■Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100 (Battery electric vehicle safety).

may result in death or serious injury.
●Never touch, disassemble, remove or replace the high voltage parts, cables or their connectors.
●The hybrid system will become hot after starting as the system uses high voltage. Becareful of both the high voltage and the hi gh temperature, and always obey the warn- ing labels attached to the vehicle.
●Never try to open the service plug accesshole located under the luggage under tray.
The service plug is used only when the vehicle is serviced and is subject to high voltage.
