IS300h_EE(OM53B95E)The SRS airbag and seat belt pretensioner devices in your Lexus contain explo-
sive chemicals. If the vehicle is scrapped with the airbags and seat belt preten-
sioners 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 professional 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 influ-
ence 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 seri-
ous 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 win-
dows, the moon roof, or other features of the vehicle. In addition, heat build-up
or extremely cold temperatures inside the vehicle can be fatal to children.

Hybrid system precautions
Take care when handling the hybrid system, as it is a high voltage system
(about 650 V at maximum) as well as contains parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle.

For safety and security
IS300h_EE(OM53B95E)
If a warning light comes on, a warning message is displayed, or the 12-volt bat-
tery is disconnected
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 warn-
ing light (P. 509) go off. If there is only a small amount of fuel, the hybrid sys-
tem may not be able to start. (The minimum amount of fuel to add to make the
low fuel level warning light go out 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 vehicle is on a
slope.)
Electromagnetic waves
High voltage parts and cables on hybrid vehicles incorporate electromagnetic
shielding, and therefore emit approximately the same amount of electromag-
netic 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 limited service life. The lifespan of the
hybrid battery (traction battery) can change in accordance with driving style and
driving conditions.
Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100
(Battery electric vehicle safety).

861-2. Hybrid system
IS300h_EE(OM53B95E)
CAUTION
High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt system.
DC and AC high voltage is very dangerous and can cause severe burns and
electric shock that 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 volt-
age. Be careful of both the high voltage and the high temperature, and always
obey the caution labels attached to the vehicle.
Never try to open the service plug access
hole located under the luggage under tray.
The service plug is used only when the
vehicle is serviced and is subject to high
voltage.

Driving
IS300h_EE(OM53B95E)
Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
Have a service technician inspect the condition of the 12-volt 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 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.
Check for and remove any excess ice or snow that may have accumu-
lated 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 get-
ting 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
vehicle in winter. Always drive the vehicle in a manner appropriate to the
