■Restraining the hybr id system output
(Brake Override System)
●When the accelerator and brake pedals
are depressed at the same time, the
hybrid system output may be restrained.
●A warning message is displayed on the
multi-information display while the sys-
tem is operating.
■Restraining sudden start (Drive-Start
Control)
●When the following unusual operation is
performed, the hybrid system output may
be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D
includes S) with the accelerator pedal
depressed, a warning message appears
on the multi-information display. If a
warning message is shown on the multi-
information display, read the message
and follow the instructions.
• When the accelerator pedal is depressed
too while the vehicl e is in reverse.
●While Drive-Start Control is being acti-
vated, your vehicle may have trouble
escaping from the mud or fresh snow. In
such case, deactivate TRAC ( P.250)
to cancel Drive-Start Control so that the
vehicle may become able to escape from
the mud or fresh snow.
■Breaking in your new Lexus
To extend the life of the vehicle, observing
the following precautions is recommended:
●For the first 200 miles (300 km):
Avoid sudden stops.
●For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for
extended periods.
●For the first 500miles (800 km):
Do not tow a trailer. (vehicles with towing
package)
■Operating your vehicle in a foreign
country
Comply with the relevant vehicle registra-
tion laws and confirm the availability of the
correct fuel. ( P.410)
■Eco-friendly driving
P.82
WARNING
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 “READY”
indicator is illuminated. 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 accelera- tor 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 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 emer gency, resulting in
an accident.
●The driver should pay extra attention
to pedestrians when the vehicle is
powered only by the electric motor
(traction motor). As there is no engine
noise, the pedestrians may misjudge
the vehicle’s movement.

ensure that all the doors and win-
dows are closed.
Confirm the type of fuel.
■Fuel types
P.410
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded

WARNING
■When refueling the vehicle
Observe the following precautions while
refueling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the ve hicle and before
opening the fuel door, touch an
unpainted metal surface to discharge
any static electricity. It is important to
discharge static electricity before refu-
eling because sparks resulting from
static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on the fuel tank
cap and turn it slowly to remove it.
A whooshing sound may be heard
when the fuel tank cap is loosened.
Wait until the sound cannot be heard
before fully removing the cap. In hot
weather, pressurized fuel may spray
out of the filler neck and cause injury.
●Do not allow anyone that has not dis-
charged static electricity from their
body to come close to an open fuel
tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are
harmful if inhaled.
●Do not smoke while refueling the vehi-
cle.
Doing so may cause the fuel to ignite
and cause a fire.
●Do not return to the vehicle or touch
any person or object that is statically
charged. This may cause static elec-
tricity to build up, re sulting in a possible
ignition hazard.
■When refueling
Observe the following precautions to
prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into the
fuel filler neck.
●Stop filling the tank after the fuel noz-
zle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such
as causing the emission control system to
operate abnormally, damaging fuel sys-
tem components or the vehicle’s painted
surface.

cap until you hear a click. Once the
cap is released, it will turn slightly in
the opposite direction. 2
Close the fuel filler door, and press
the center of the rear edge of the
fuel filler door.
When you lock the doors, the fuel filler
door will lock also.
■Fuel filler door lock condition
The fuel filler door may not be locked even
when the vehicle’s doors are locked in the
following conditions:
●When operating the door lock button
inside the vehicle
●When the automatic door locking system
is operated
●When the fuel filler door is closed after
the vehicle’s doors are locked

■Windshield wiper de-icer (if
equipped)
P.271
■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air
mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a
default mode when the power switch is
turned to ON mode.
●It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■Fogging up of the windows
●The windows will easily fog up when the
humidity in the vehicle is high. Pressing
“A/C” button or selecting “A/C” will
dehumidify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows may
fog up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tun-
nels or in heavy traffic, set the outside/
recirculated air mode switch to the recir-
culated air mode. This is effective in pre-
venting outside air from entering the
vehicle interior. During cooling opera-
tion, setting the recirculated air mode will
also cool the vehicle interior effectively.
●Outside/recirculated air mode may auto-
matically switch de pending on the tem-
perature setting or the inside
temperature.
■Registering air condit ioning settings to
electronic keys (vehicles with driving
position memory)
●Unlocking the vehicle using an electronic
key and turning the power switch to ON
mode will recall that key’s registered air conditioning settings.
●When the power switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
●The system may not operate correctly if
more than one electr
onic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.
●The doors that can recall the air condi-
tioning setting when unlocked using the
smart access system with push-button
start can be changed.
* For details, con-
tact your Lexus dealer.
*: The doors that can recall the driving posi-
tion memory are changed at the same
time.
■Operation of the air conditioning sys-
tem in Eco mode
●In the Eco mode, the air conditioning sys-
tem is controlled as follows to prioritize
fuel efficiency
• Engine speed and compressor operation
controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic mode is selected
●To improve air conditioning performance,
perform the following operations
• Adjust the fan speed
• Adjust the temperature setting
• Turn off Eco mode
●Even when the driving mode is set to Eco
mode, the air conditioning eco mode can
be turned off by selecting the
■When the outside temperature is low
The dehumidification function may not
operate even when “A/C” is pressed or “A/
C” is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
●During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning sys-
tem. This may then cause odor to be
