CAUTION
■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 hybrid system under any circumstances.
Doing so may cause an accident resulting 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 complete stop. Activation of the steering lock
in this circumstance may lead to an accident, 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 seconds, or press it briefly 3 times or more
in succession. (→P. 4 9 5 )
However, do not touch the power switch while 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 “ACCESSORY” or “IGNITION ON” is displayed on the meters while the hybrid
system is not operating, 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
●Do not depress the accelerator pedal unnecessarily.
●If the hybrid system becomes difficult to start, have your vehicle checked by any
authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional immediately.
■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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional immediately.

■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 after a short period of time in order to warm up. In this 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 engine 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 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 2 2 )
●Vehicle speed becomes more than about 45 km/h (28 mph).
●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 approxi-
mately 2 km (1.2 mile). Driving is possible at speeds of less than approximately 45 km/h
(28 mph). However, depending 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
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.
CAUTION
■Caution while driving
When driving in EV drive mode, pay special attention to the area around the vehicle.
Because there is no engine noise, pedestrians, people riding bicycles or other people
and vehicles in the area may not be aware of the vehicle starting off or approaching
them, so take extra care while driving.
