■When starting the hybrid system
Always start the hybrid system while sittin
g in the driver’s seat. Do not depress the
accelerator pedal while starting the hybrid 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. 4 9 3 )
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.

Driving
EV drive mode
Turns EV drive mode on/off
When EV drive mode is turned on, the
EV drive mode indicator will come on.
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-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 68 F (20 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” screen is low. (P. 9 7 )
●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.

ES300h_OM_OM33B71U_(U)4-2. Driving procedures
■Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is starte
d 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.
After the hybrid system has started and the “READY” indicator has illuminated, press the
EV drive mode switch before the gasoline en gine starts 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 canceled, a buzzer will sound and the EV indi-
cator will flash 3 times and go off.
●The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy Monitor” screen is low. (P. 9 7 )
●Vehicle speed is 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 1.3 mile (2 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 electr ic motor [traction motor]). Driving in EV
drive mode more than necessary may lower fuel economy.
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.

To enter S mode, shift the shift lever to S. Shift ranges can then be selected by
operating the shift lever, allowing you to
drive in the shift range of your choosing.
Upshifting
Downshifting
The selected shift range, from 1 to 6, will
be displayed in the meter.
The initial shift range in S mode is auto-
matically set to 4 to 5 according to vehi-
cle speed.
■Shift ranges and their functions
●You can choose from 6 levels of engine braking force.
●A lower shift range will provide greate r engine braking force than a higher
shift range, and the engine revolutions will also increase.
●If you accelerate while in ranges 1 to 4, the shift range may automatically
range up in accordance with the vehicle’s speed.

■S mode
●When the shift range is 4 or lower, holding the shift lever toward “+” sets the shift range
to 6.
●To prevent excessive engine speed, a function was adopted that automatically selects a
higher shift range before the engine speed becomes too high.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
the engine brake will not operate in the S mo de, even when downshifting to 5 or 4.
( P. 2 3 4 )
■Downshifting restrictions warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever is operated. (A buzzer will sound twice.)
■If the S indicator does not come on ev en after shifting the shift lever to S
This may indicate a malfunct ion in the hybrid transmission system. Have the vehicle
inspected by your Lexus dealer immediately.
(In this situation, the transmission will operat e in the same manner as when the shift lever
is in D.)
■If the shift lever cannot be shifted from P
P. 5 2 0
■AI-SHIFT
AI-SHIFT automatically select s the suitable gear according to driver performance and
driving conditions.
AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever to S
cancels the function.)
WA R N I N G
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause th e vehicle to spin or skid, resulting in an
accident.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid batter y (traction battery) will not be charged even
when the engine is running. Therefore, if the ve hicle is left with the shift lever in N for a
long period of time, the hybrid battery (tr action battery) will discharge, and this may
result in the vehicle not being able to start.
