3-5. Opening, closing the windows and moon roof
■Moon roof open warning buzzer
The buzzer sounds and a message is shown on the multi-information display in the
instrument cluster when the power switch is turned off and the driver’s door is
opened with the moon roof open.
■Customization
Settings (e.g. linked door lock operation) can be changed.
(Customizable features: →P. 599)
CAUTION
Observe the following precautions.
Failure to do so may cause death or serious injury.
■Opening the moon roof
●Do not allow any passengers to put their hands or heads outside the vehicle while
it is moving.
●Do not sit on top of the moon roof.
■Closing the moon roof
●The driver is responsible for moon roof opening and closing operations.
In order to prevent accidental operation, especially by a child, do not let a child
operate the moon roof. It is possible for children and other passengers to have
body parts caught in the moon roof.
●Check to make sure that all passengers do not have any part of their body in a
position where it could be caught when the moon roof is being operated.
●When using the mechanical key and operating the moon roof, operate the moon
roof after checking to make sure that there is no possibility of any passenger hav-
ing any of their body parts caught in the moon roof. Also, do not let a child oper-
ate moon roof by the mechanical key. It is possible for children and other
passengers to get caught in the moon roof.
●When exiting the vehicle, turn the power switch off, carry the key and exit the
vehicle along with the child. There may be accidental operation, due to mischief,
etc., that may possibly lead to an accident.
■Jam protection function
●Never use any part of your body to intentionally activate the jam protection func-
tion.
●The jam protection function may not work if something gets caught just before
the moon roof fully closes.

■Operation of the power switch
●When operating the power switch, one short, firm press is enough. If the switch is
pressed improperly, the hybrid system may not start or the power switch mode may
not change. It is not necessary to press and hold the switch.
●If attempting to restart the hybrid system immediately after turning the power
switch off, the hybrid system may not start in some cases. After turning the power
switch off, please wait a few seconds before restarting the hybrid system.

NOTICE
■To prevent 12-volt battery discharge
●Do not leave the power switch in ACCESSORY or ON mode for long periods of
time without the hybrid system on.
●If “POWER ON” is displayed on the multi-information display, the power switch
is not off. Exit the vehicle after turning the power switch off.
●Do not stop the hybrid system when the shift lever is in a position other than P. If
the hybrid system is stopped in another shift lever position, the power switch will
not be turned off but instead be turned to ACCESSORY mode. If the vehicle is
left in ACCESSORY mode, 12-volt battery discharge may occur.
■Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating somewhat differently than usual, such as
the switch sticking slightly, there may be a malfunction. Contact your Lexus dealer
immediately.

4-2. Driving procedures
EV drive mode
Turns EV drive mode on/off
When EV drive mode is turned on,
“EV MODE” will be displayed on the
multi-information display. Pressing the
switch when in EV drive mode will
return the vehicle to normal driving
(using the gasoline engine and electric
motor [traction motor]).
■Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If it cannot
be turned on, a buzzer will sound and a message will be shown on the multi-informa-
tion display.
●The temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds, etc.
●The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 32
°F (0°C) for a long
period of time etc.
●The gasoline engine is warming up.
●The hybrid battery (traction battery) is low.
The remaining battery level indicated in the “Energy Monitor” display is low.
( → P. 1 1 2 )
●Vehicle speed is about 25 mph (40 km/h) or more.
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
●The windshield defogger is in use.
In EV drive mode the electric motor (traction motor), powered by the
hybrid battery (traction battery), is used to drive the vehicle.
This mode allows you to drive in re sidential areas early in the morning
and late at night, or in indoor pa rking lots etc. without concern for
noises and gas emissions.
However, when the vehicle proximity notification system is active, the
vehicle may produce sound.

Driving
■Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline engine
will start automatically in order to warm up. In this case, you will become unable to
switch to EV drive mode.
■Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in the
following situations. When EV drive mode is canceled, a buzzer will sound and the
EV drive mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy Monitor” display is low.
( → P. 1 1 2 )
●Vehicle speed becomes more than about 25 mph (40 km/h).
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance, a prior
notice screen will appear on the multi-information display.
■Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters to
approximately 0.6 mile (1 km). Driving is possible at speeds of less than approxi-
mately 25 mph (40 km/h). However, depending on vehicle conditions, there are sit-
uations when EV drive mode cannot be used.
(The distance that is possible depends on the hybrid battery [traction battery] level
and driving conditions.)
■Fuel economy
Your Lexus is designed to achieve the best possible fuel economy during normal
driving (using the gasoline engine and electric motor [traction motor]). Driving in EV
drive mode more than necessary may lower fuel economy. To prevent gasoline engine warm up in order
to reduce noises, start the hybrid system with-
out starting the gasoline engine, pressing the
power switch with fully depressing the brake
pedal and pressing the EV drive mode switch.

Driving
To drive using temporary shift range selection, operate the “-” or “+” pad-
dle shift switch.
When the “-” paddle shift switch is operated, the shift range will be down-
shifted to a range that enables engine braking force that is suitable to driv-
ing conditions. When the “+” paddle shift switch is operated, the shift
range will be one gear upper than the gear in use during normal D posi-
tion driving.
Changing the shift range allows restriction of the highest shift range, pre-
venting unnecessary upshifting and enabling the level of engine braking
force to be selected.
Upshifting
Downshifting
The selected shift range, from D1 to
D8, will be displayed in the meter.
To return to normal D position driving,
the “+” paddle shift switch must be
held down for a period of time.
■Shift ranges and their functions
A lower shift range will provide greater engine braking forces than a higher shift
range.
