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 will hurt or kill you, your occupants or others.
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.
■ When children are in the vehicle
Never leave children unattended in the vehicle.
When left unattended, 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 cigarette lighter, the windows, 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.
■ Dispose of the hybrid battery (traction battery)
If your vehicle is disposed of without the hybrid battery having been removed, there
is a danger of serious electric shock if high voltage parts, cables and their connectors are touched. In the event of that your vehicle must be disposed of, the hybrid
battery must be disposed of your Lexus dealer or a qualified service shop. If the
hybrid battery is not disposed of properly, they may cause electric shock that can
result in death or serious injury.

1-1.Hybrid system ............................... 2
Your vehicle is a hybrid vehicle. It has characteristics different from conventional vehicles. Be sure you are closely familiar
with the characteristics
of your vehicle, and operate with care.
The hybrid system combines a gasoline e
ngine and an electric motor (traction motor) according to driving conditions, improving fuel efficiency and
r
educing exhaust emissions.
Gasoline engine
Electric motor (Traction motor)
■ When stopped/during take-off
The gasoline engine stops when the vehicle is stopped. During takeoff, the electric motor (traction motor) drives the vehicle. At slow
speeds or when traveling down a gentle slope, the engine is stopped
and the motor is used.
Hybrid system

■ Regenerative braking
■ During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid battery as necessary.
■ When accelerating sharply
The power of the hybrid battery (traction battery) is added via electric motor (traction motor) to that of the gasoline engine.
■ When braking (Regenerative brake)
The electric motor (traction motor) charges the hybrid battery
(traction battery).
The motor generator converts kinetic energy to electric energy when:
● The accelerator pedal is released.
● The brake pedal is depressed with the shift lever in “D” or “S”.
■ Conditions in which the gasoline engine may not stop
The gasoline engine starts and
matically in the following conditions:
● During gasoline engine warm-up
● During hybrid battery (traction battery) charging
● During low or high hybrid battery (traction battery) temperature
■ Charging the battery
● As the gasoline engine charges the hybrid battery (traction battery), the battery
does not need to be charged from an outside source. However, if the vehicle is
left parked for a long time the hybrid battery will slowly discharge. For this reason, be sure to drive the vehicle at least once every few months for at least 30
utes or 10 miles (16 km). If the hybrid battery becomes fully discharged and
min
you are unable to jump-start the vehicle with the 12 volt battery, contact your
Lexus dealer.
● If the shift lever is in “N”, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift lever in
“D” or “S” to avoid discharging the battery.

■ After the 12 volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is running on the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.
■ Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to
move. Always put the shift lever in “P” when parked.
The following sounds or vibrations may occur when the hybrid system is operating,
and are not a malfunction.
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) behind the rear
seat when the hybrid system starts or stops.
● Sounds may be heard from the transmission when the hybrid system starts or
stops.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard from the regenerative brake when you press the brake
pedal.
● Vibration may be felt when the gasoline engine starts or stops.
● You may hear cooling fan sounds coming from the air intake vents behind the
rear seat.

tery is disconnected
The hybrid system may not start. In that case, try to start the system again. If the
“READY” light does not come on, contact your Lexus dealer.
■ High voltage precautions
The 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 and
their connectors.
● The hybrid system will become hot after starting as the system uses high voltage.
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 in the luggage compart-
ment. The service plug is used only when the vehicle is serviced and is subject to
high voltage.

■ Road accident cautions
Observe the following precautions to reduce the risk of injury.
● Pull your vehicle off the road, put the shift lever in “P”, apply the parking brake,
turn the hybrid system off.
● Do not touch the high voltage parts, cables and connectors.
● If electric wires are exposed inside or outside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch it as it may be strong alkaline electrolyte from
the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or if possible, boric
acid solution. Seek immediate medical attention.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never
use a fire extinguisher that is not meant for electric fires. Using even a small
amount of water may be dangerous.
● If your vehicle needs to be towed, do so with the rear wheels raised. If the wheels
with the electric motor (traction motor) are on the ground when towing, the
motor may continue to generate electricity. This may cause an electricity leakage
leading to a fire.(
■ Nickel-metal hydride battery
P. 4 20 )
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of improperly, it is hazardous to the environment and there is a risk of severe burns and electrical shock that may result in death or serious injury.
■ Emergency shut off system
