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 vehi-
cle, press and hold the power switch for more than 2 seconds, or press it briefly
3 times or more in succession. (P. 499)
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, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, 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 professional 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 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. 123)
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.

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 2 km (1.2 mile). Driving is possible at speeds of less than approx-
imately 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.
