■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the hy brid system under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.
■Caution while driving
If hybrid system failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and comp lete stop. Activation of the steering lock
in this circumstance may lead to an acci dent, resulting in death or serious injury.
■Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehicle, press
and hold the power switch for more than 2 se conds, or press it briefly 3 times or more
in succession. ( P. 393)
However, do not touch the power switch whil e driving except in an emergency. Turning
the hybrid system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will make it more difficult to steer
smoothly, so you should pull over and stop the vehicle as soon as it is safe to do so.
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.
■When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by your Lexus
dealer immediately.
■Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating so mewhat differently than usual, such as the
switch sticking slightly, there may be a malf unction. Contact your Lexus dealer immedi-
ately.

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 gas-
oline engine and elec tric 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-information dis-
play.
●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 0 8 )
●Vehicle speed is high.
●The accelerator pedal is depressed firm ly or the vehicle is on a hill etc.
●The windshield defogger is in use.
In EV drive mode, electric power is su pplied by the hybrid battery (traction
battery), and only the electric motor (tra ction motor) is used to drive the vehi-
cle.
This mode allows you to drive in residential areas early in the morning and late
at night, or in indoor parking lots etc. without concern for noises and gas emis-
sions.
However, when the vehicle proximity noti fication system is active, the vehicle
may produce sound.

4-2. Driving procedures
■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 th is 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 fol-
lowing situations. When EV drive mode is ca nceled, 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 0 8 )
●Vehicle speed high.
●The accelerator pedal is depressed firm ly 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 ra nges from a few hundred meters to approxi-
mately 0.6 mile (1 km). However, dependin g on vehicle conditions, there are situations
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
The hybrid system 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 without
starting the gasoline engine, pressing the power
switch with fully depressing the brake pedal and
pressing the EV drive mode switch.
WA R N I N G
■Caution while driving
When driving in EV drive mode no engine noise is made. As such, pedestrians, people
riding bicycles or other people and vehicles in the surrounding area may not be aware
of the vehicle starting off or approaching them. Therefore, take extra care while driving
even if the vehicle proximity notification system is active.

Driving
To drive using temporary shift range selection, operate the “-” or “+” paddle shift
switch.
When the “-” paddle shift switch is operated, the shift range will be downshifted
to a range that enables engine braking forc e that is suitable to driving conditions.
When the “+” paddle shift switch is operated, the shift range will be one gear
upper than the gear in use during normal D position driving.
Changing the shift range allows restrictio n of the highest shift range, preventing
unnecessary upshifting and enabling the level of engine braking force to be
selected.

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 engi ne braking forces than a higher shift
range.

The initial shift range in S mode is auto-
matically set to between S2 and S6
according to vehicle speed.
■Shift ranges and their functions
●You can choose from 8 levels of accelerating force and engine braking
force.
●A lower shift range will provide greater accelerating force and engine
braking force than a higher shift rang e, and the engine revolutions will also
increase.
●If you accelerate while in ranges 1 to 7, the shift range may automatically
range up in accordance with the vehicle’s speed.
