Gasoline engine
Electric motor (traction motor)
■When stopped/during start off
The gasoline engine stops
* when the
vehicle is stopped. During start off, the
electric motor (traction motor) drives
the vehicle. At slow speeds or when
traveling down a gentle slope, the
engine is stopped
* and the electric
motor (traction motor) is used.
When the shift lever is in N, the hybrid
battery (traction battery) is not being charged.
*: When the hybrid battery (traction bat-
tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop.
■During normal driving
The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery
(traction battery) as necessary.
Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics different from conven-
tional vehicles. Be sure you are closely familiar with the characteristics of your
vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and an electric motor
(traction motor) according to driving conditions, improving fuel efficiency and
reducing exhaust emissions.

■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.368) 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 2.4gal. [9.0 L, 2.0 Imp.gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
Hybrid system precautions
Take care when handling the hybrid sy
stem, 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 warning labels attached to
the vehicle.

WARNING
●For vehicles sold in except Canada:
Do not touch the battery if liquid is
leaking from or adhering to it. If elec-
trolyte (carbonic-based organic elec-
trolyte) from the hybrid battery
(traction battery) comes into contact
with the eyes or skin, it could cause
blindness or skin wounds. In the
unlikely event that it comes into con-
tact with the eyes or skin, wash it off
immediately with a large amount of
water, and seek immediate medical
attention.
●If electrolyte is leaking from the hybrid
battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the
hybrid battery (traction battery) is
damaged, the internal construction of
the battery will prevent a large amount
of electrolyte from leaking out. How-
ever, any electrolyte that does leak out
will give off a vapor. This vapor is an
irritant to skin and eyes and could
cause acute poisoning if inhaled.
●Do not bring burning or high-tem-
perature items close to the electrolyte.
The electrolyte may ignite and cause a
fire.
●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 danger-
ous.
●If your vehicle needs to be towed, do
so with front wheels raised. If the
wheels connected to the electric
motor (traction motor) are on the
ground when towing, the motor may
continue to generate electricity. This
may cause a fire. ( P.361)
●Carefully inspect the ground under the
vehicle. If you find that liquid has
leaked onto the ground, the fuel sys-
tem may have been damaged. Leave
the vehicle as soon as possible.
■Hybrid battery (traction battery)
●Your vehicle contains a sealed lithium-
ion battery.
●Never resell, hand over or modify the
hybrid battery. To prevent accidents,
hybrid batteries that have been
removed from a disposed vehicle are
collected through Lexus dealer. Do
not dispose of the battery yourself.
Unless the battery is properly col-
lected, the following may occur, result-
ing in death or serious injury:
• The hybrid battery may be illegally dis- posed of or dumped, and it is hazard-
ous to the environment or someone
may touch a high voltage part, result-
ing in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid vehi-
cle. If the hybrid battery is used outside
of your vehicle or modified in any way,
accidents such as electric shock, heat
generation, smoke generation, an
explosion and electrolyte leakage may
occur.
When reselling or handing over your
vehicle, the possibility of an accident is
extremely high because the person
receiving the vehicle may not be aware
of these dangers.
●If your vehicle is disposed of without
the hybrid battery having been
removed, there is a danger of serious
electric shock if hi gh voltage parts,
cables and their connectors are
touched. In the event that your vehicle
must be disposed of, the hybrid battery
must be disposed of by your Lexus
dealer or a qualified service shop. If the
hybrid battery is not disposed of prop-
erly, it may cause electric shock that
can result in death or serious injury.

For safety and security
There is an air intake vent under the
rear seat (right side) for the purpose of
cooling the hybrid battery (traction
battery). If the vent becomes blocked,
the hybrid battery (traction battery)
may overheat, leading to a reduction in
the hybrid battery (traction battery)
output.When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks the
high voltage current and stops the fuel
pump to minimize the risk of electrocu-
tion and fuel leakage. If the emergency
shut off system activates, your vehicle
will not restart. To restart the hybrid
system, contact your Lexus dealer.
A message is automatically displayed
when a malfunction occurs in the
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the
multi-information display, read the
NOTICE
■Hybrid battery (traction battery)
Do not carry large amounts of water
such as water cooler bottles in the vehi-
cle. If water spills onto the hybrid battery
(traction battery), the battery may be
damaged. Have the vehicle inspected by
your Lexus dealer.
Hybrid battery (traction battery)
air intake vent
NOTICE
■Hybrid battery (traction battery) air
intake vent
●Make sure not to block the air intake
vent with anything, such as a seat
cover, plastic cover, or luggage. If the
vents become blocked, the hybrid bat-
tery (traction battery) input and output
may be restricted, leading to a reduc-
tion in hybrid battery (traction battery)
output and a malfunction.
●When dust etc. has accumulated in the
air intake vent, periodically clean it
with a vacuum cleaner to prevent the
vent from clogging.
●A filter is installed to the air intake vent.
When the filter re mains noticeably
dirty even after cleaning the air intake
vent, filter cleaning or replacement is
recommended. When cleaning or
replacing the filter, contact your Lexus
dealer.
Refer to P.344 for details on how to
clean the filter.
●Do not get water or foreign materials
in the air intake vent as this may cause
a short circuit and damage the hybrid
battery (traction battery).
●Do not carry large amounts of water
such as water cooler bottles in the
vehicle. If water spills onto the hybrid
battery (traction battery), the battery
may be damaged. Have the vehicle
inspected by your Lexus dealer.

WARNING
■If a safety system warning light does
not come on
Should a safety system light such as the
ABS and SRS warning light not come on
when you start the hybrid system, this
could mean that these systems are not
available to help protect you in an acci-
dent, which could result in death or seri-
ous injury. Have the vehicle inspected by
your Lexus dealer immediately if this
occurs.
