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.

Driving
IS300h_EE(OM53B95E)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid system
operating. This prevents the vehicle from creeping.
When driving the vehicle
Do not drive if you are unfamiliar with the location of the brake and accelera-
tor pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal
will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty
in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly. This allows you to depress the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay response in an emergency, resulting in an
accident.
The driver should pay extra attention to pedestrians when the vehicle is pow-
ered only by the electric motor (traction motor). As there is no engine noise,
the pedestrians may misjudge the vehicle’s movement.
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts
may cause a fire if there is any flammable material nearby.
During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control, but
the power assist to these systems will be lost. This will make it more difficult
to steer and brake, so you should pull over and stop the vehicle as soon as it is
safe to do so.
However, in the event of an emergency, such as if it becomes impossible to
stop the vehicle in the normal way: P. 499
Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 216)
Do not adjust the positions of the steering wheel, the seat, or the inside or out-
side rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
Always check that all passengers’ arms, heads or other parts of their body are
not outside the vehicle.

Driving
IS300h_EE(OM53B95E)
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turn-
ing on slippery road surfaces
VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
Hill-start assist control
Prevents the vehicle from rolling backward when starting on an incline
or slippery slope
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
