trations used may differ from your vehi-
cle.
All specifications provided in this man-
ual are current at the time of printing.
Over time, your vehicle may receive
updates that modify the vehicle and
make material in this manual incom-
plete and/or inaccurate. Because of
Lexus’ interest in continual product
improvement, Lexus reserves the right
to make changes to this manual at any
time without notice.

Approximately five hours after the
hybrid system is turned off, you may
hear sound coming from under the
vehicle for several minutes. This is the
sound of a fuel evaporation leakage
check and, it does not indicate a mal-
function. A wide variety of non-genuine spare
parts and accessories for Lexus vehi-
cles are currently available in the mar-
ket. You should know that Toyota does
not warrant these products and is not
responsible for their performance,
repair, or replacement, or for any dam-
age they may cause to, or adverse
effect they may have on, your Lexus
vehicle.
This vehicle should not be modified
with non-genuine Lexus products.
Modification with non-genuine Lexus
products could affect its performance,
safety or durability, and may even vio-
late governmental regulations. In addi-
tion, damage or performance
problems resulting from the modifica-
tion may not be covered under war-
ranty.
Also, remodeling like this will have an
effect on advanced safety equipment
such as Lexus Safety System + 2.0 and
there is a danger that it will not work
properly or the danger that it may work
in situations where it should not be
working.
The installation of a mobile two-way
radio system in your vehicle could
affect electronic systems such as:

For safety and security
used. The electric motor (traction
motor) charges the hybrid battery
(traction battery) as necessary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of the
hybrid battery (traction battery) is
added to that of the gasoline engine via
the electric motor (traction motor).
■When braking (regenerative brak-
ing)
The wheels operate the electric motor
(traction motor) as a power generator,
and the hybrid battery (traction bat-
tery) is charged.
■Regenerative braking
In the following situations, kinetic energy is
converted to electric energy and decelera-
tion force can be obta ined in conjunction
with the recharging of the hybrid battery
(traction battery).
●The accelerator pedal is released while
driving with the shift lever in D or S.
●The brake pedal is depressed while driv-
ing with the shift lever in D or S.
■EV indicator
The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or the gasoline engine is
stopped.
■Conditions in which the gasoline engine
may not stop
The gasoline engine starts and stops auto-
matically. However, it may not stop auto- matically in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (traction battery)
charging
●When the temperature of the hybrid bat-
tery (traction battery) is high or low
●When the heater is switched on
Depending on the circumstances, the gaso-
line engine may also not stop automatically
in other situations.
■Charging the hybrid battery (traction
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 (traction
battery) will slowly discharge. For this rea-
son, be sure to drive the vehicle at least
once every few months for at least 30 min-
utes or 10 miles (16 km). If the hybrid bat-
tery (traction battery) becomes fully
discharged and you are unable to start the
hybrid system, contact your Lexus dealer.
■Charging the 12-volt battery
P.441
■After the 12-volt battery has discharged
or when the terminal has been removed
and installed during exchange, etc.
The gasoline engine may not stop even if
the vehicle is being driven by the hybrid bat-
tery (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 sound or vibration
even though the vehicle is able to move with
the “READY” indicator is illuminated. For
safety, apply the parking brake and make
sure to shift the shift lever to 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
