Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find some explanations for equipment
not installed on your vehicle.
All specifications provided in this man- ual are current at the time of printing.
However, because of the Lexus policy
of continual product improvement, we
reserve the right to make changes at
any time without notice.
Depending on specifications, the vehi-
cle shown in the illustrations may differ
from your vehicle in terms of color and
equipment.
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

repair, or replacement, or for any dam-
age they may cause to, or adverse

WARNING
■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 coordina-
tion, which could lead to an accident that
could result in death or serious injury.
Defensive driving: Always drive defen-
sively. 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 dis-
tracts the driver, such as adjusting con-
trols, 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 chil-
dren’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 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.

For safety and security
charged.
*: When the hybrid battery (traction bat-tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop. ( P.63)
■During normal driving
The gasoline engine is predominantly
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 th e 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 gasoline engine may also not stop auto-
matically 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.408
■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.

■Hybrid System Indicator
Charge area
Shows regeneration* status.
Regenerated energy will be used to charge
the hybrid battery (traction battery).
Hybrid Eco area
Shows that gasoline engine power is not
being used very often.
The gasoline engine will automatically stop
and restart under various conditions.
Eco area
Shows that the vehicle is being driven in an
Eco-friendly manner.
By keeping the bar display within Eco area,
more Eco-friendly driv ing can be achieved.
Power area
Shows that an Eco-friendly driving range is
being exceeded (durin g full power driving
etc.)
*: When used in this manual, regeneration refers to the conversion of energy cre-
ated by the movement of the vehicle into
electrical energy.
■Engine speed
On hybrid vehicles, engine speed is pre-
cisely controlled in order to help improve
fuel efficiency and reduce exhaust emis- sions etc.
There are times when the engine speed that
is displayed may differ even when vehicle
operation and driving
conditions are the
same.
■Hybrid System Indicator is displayed
when
The Hybrid System Indicator is displayed in
the following situations:
●The shift lever is in D or S.
●The driving mode is other than Sport
mode.
■Outside temperature display
●In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])
• When the outside temperature has
changed suddenly (at the entrance/exit of
a garage, tunnel, etc.)
●When “--” or “E” is displayed, the system
may be malfunctioning. Take your vehicle
to your Lexus dealer.
■Speed unit setting for the speedometer
When the speed unit has been changed
from the default setting, the vehicle speed in
the default unit is also displayed in the
meter.

■Display items
Odometer
Displays the total distance the vehicle has
been driven.
Trip meter A/trip meter B
Displays the distance the vehicle has been
driven since the meter was last reset. Trip
meters A and B can be used to record and display different distances independently.
Distance until next engine oil
change
Displays the distance the vehicle can be
driven until an oil change is necessary.
■Changing the display
Each time the “ODO TRIP” switch is
pressed, the displayed item will be
changed. When the trip meter is dis-
played, pressing and holding the switch
will reset the trip meter.
■Pop-up display
Distance until the next engine oil
change will displayed when a warning
message indicating that oil mainte-
nance should be performed soon or is
required is displayed.
The brightness of the instrument panel
lights can be adjusted.
WARNING
■The information display at low tem-
peratures
Allow the interior of the vehicle to warm
up before using the liquid crystal infor-
mation display. At extremely low tem-
peratures, the information display
monitor may respond slowly, and display
changes may be delayed.
For example, there is a lag between the
driver’s shifting and the new gear number
appearing on the display. This lag could
cause the driver to downshift again,
causing rapid and excessive engine brak-
ing and possibly an accident resulting in
death or injury.
NOTICE
■To prevent damage to the engine and
its components
●Do not let the indicator of the tachom-
eter enter the red zone, which indi-
cates the maximum engine speed.
●The engine may be overheating if the
engine coolant temperature gauge is
in the red zone (H). In this case, imme-
diately stop the vehicle in a safe place,
and check the engine after it has
cooled completely. ( P.410)
