■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON
mode (the hybrid system is not operating) for more than an hour with the shift
lever in P, the power switch will automatically turn off. However, this function
cannot entirely prevent 12-volt battery discharge. Do not leave the vehicle
with the power switch in ACCESSORY or ON mode for long periods of time
when the hybrid system is not operating.
■ Sounds and vibrations specific to a hybrid vehicle
 P. 8 9
■ Electronic key battery depletion
 P. 477
■ When the ambient temperature is low, such as during winter driving con-
ditions
When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indicator is steady
on, as steady means the vehicle is able to move.
■ Conditions affecting operation
 P. 168
■ Notes for the entry function
 P. 169
■ If the hybrid system does not start
● The immobilizer system may not have been deactivated. (P. 9 6 )
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
● Check that the shift lever is securely set in P. The hybrid system may not
start if the shift lever is displaced out of P.

■ Steering lock
After turning the power switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
power switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system. After about 10
seconds, the steering lock motor will resume functioning.
■ If the “READY” indicator does not come on
If the event that the “READY” indicator does not come on even after perform-
ing the proper procedures for starting t he vehicle, contact any authorized Toy-
ota retailer or Toyota authorized repair er, or any reliable repairer immediately.
■ If the hybrid system is malfunctioning
 P. 91, 518
■ If the electronic key battery is depleted
 P. 477
Vehicles with monochrome display: The
smart entry & start system indicator light
(green) will flash quickly.
Vehicles with color display: “Steering lock
active.” will be displayed on the multi-
information display.
Check that the shift lever is set in P.
Press the power switch while turning the
steering wheel left and right.

NOTICE
■To prevent 12-volt battery discharge
● Do not leave the power switch in ACCESSORY or ON mode for long peri-
ods of time without the hybrid system on.
● Vehicles with monochrome display: If the smart entry & start system indi-
cator (green) is illuminated, the power switch is not off. When exiting the
vehicle, always check that the power switch is off.
● Vehicles with color display: If “Power on” is displayed on the multi-informa-
tion display, the power switch is not off. When exiting the vehicle, always
check that the power switch is 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 dis-
charge may occur.
■ When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer 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 Toyota retailer or Toyota authorized repairer, or any
reliable repairer immediately.

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 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 0°C (32°F) for a
long period of time etc.
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is low.
• In the instrument cluster, the low traction battery warning light comes on.
( P. 521)
• The remaining battery level indicated in the energy monitor display is low.
( P. 133)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.
In EV drive mode, electric power is supplied by the hybrid bat-
tery (traction battery), and only the electric motor (traction
motor) is used to drive the vehicle.
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 emissions.

■ 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 illumi-
nated, 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.
• In the instrument cluster, the low traction battery warning light comes on.
( P. 521)
• The remaining battery level indicated in the energy monitor display is low.
( P. 133)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
■ Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters
to approximately 1 km (0.6 miles). 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
The hybrid system is designed to achieve the best possible fuel economy
during normal driving (using the gasol ine engine and electric motor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.

WARNING
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal
when the shift lock override button is pressed and the shift lever is shifted
out of P, the vehicle may suddenly start leading to an accident which may
result in death or serious injury.
NOTICE
■ Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery fr om discharging, avoid leaving the N
position selected for an extended period of time.
