When driving
■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 position in P, the “POWER” switch will automatically turn off. However,
this function cannot entirely prevent the 12-volt battery from discharging. 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. 4 2
■Electronic key battery depletion
→P. 1 2 3
■When the ambient temperature is low, such as during winter driving
conditions
The “READY” indicator may flash for a long time when the hybrid system is
starting. Driving will become possible once the “READY” indicator has illumi-
nated. Wait until the “READY” indicator has illuminated.
■Conditions affecting operation

■Notes for the entry function
→P. 1 2 0
■If the hybrid system does not start
●The immobilizer system may not have been deactivated. (→P. 1 7 9 )
Contact your Toyota dealer.
●The charging cable may be connected to the vehicle. (→P. 9 1 )

When driving
■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. (→P. 2 4 7 ) To i m p r o v e a i r
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■For the shift positions
●When the “POWER” switch is off, the shift position cannot be changed.
●When the “POWER” switch is in ON mode (the hybrid system is not oper-
ating), the shift position can only be changed to N. The shift position will
be changed to N even if the shift lever is shifted to D or R and held in that
position.
However, immediately after turning the “POWER” switch to ON mode,
the shift position may not change to N.
●When the “READY” indicator is on, the shift position can be changed
from P to D, N or R.
●When the “READY” indicator is flashing, the shift position cannot be
changed from P to other position even if the shift lever is operated. Wait
until the “READY” indicator changes from a flashing to a solid light, and
then operate the shift lever again.
●The shift position can only be changed to B directly from D.
In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions, the buzzer will sound and the shifting operation will be disabled or the
shift position will automatically change to N. When this happens, select an
appropriate shift position.
●Situations where the shifting operation will be disabled:
•When an attempt is made to change the shift position from P to other
position by moving the shift lever without depressing the brake pedal.
•When an attempt is made to change the shift position from P or N to B
by moving the shift lever.
•When an attempt is made to change the shift position from P to another
position by moving the shift lever while the charging cable is connected
to the vehicle.

When driving
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
●When the vehicle is driven at high speeds, compared to ordinary gaso-
line-fueled vehicles, the engine braking deceleration is felt less than that
of other vehicles.
●The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, shift the shift position to D.
■When driving with cruise control or radar cruise control activated
Even if switching the driving mode to power mode with the intent of enabling
engine braking, engine braking will not activate because cruise control or
radar cruise control will not be canceled.
■When canceling Eco drive mode/power mode
●Press the switch again. Also, power mode will be canceled automatically
when the “POWER” switch is turned off. However, Eco drive mode will
not be canceled automatically until the switch is pressed, even if the
“POWER” switch is turned off.
●When in Eco drive mode, if the power mode switch is pressed or the
operation is reversed, the mode will switch to that of the last switch to be
pressed.

■Customization
Settings (e.g. Reverse warning buzzer) can be changed.

NOTICE
■Hybrid battery (traction battery) charge
If the shift position is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid leaving the N
position selected for an extended period of time.
■Situations where P position control system malfunctions are possible
If any of the following situations occurs, P position control system malfunc-
tions are possible.
Immediately stop the vehicle in a safe place on level ground, apply the park-
ing brake, and then contact your Toyota dealer.
●When the “P LOCK MALFUNCTION” warning message appears on the
multi-information display. (→P. 5 4 8 )
●When the shift position indicator remains off.
■Notes regarding shift lever and P position switch operation
Avoid repeatedly operating the shift lever and P position switch in quick suc-
cession.
The system protection function may activate and it will temporarily not be
possible to shift the shift position other than P. If this happens, please wait
for a while before attempting to change the shift position again.

Interior features
Remote Air Conditioning System
The Remote Air Conditioning System uses electrical energy stored
in the hybrid battery (traction battery) and allows the air conditioning
to be operated by remote control.
If the Remote Air Conditioning System is used while the charging
cable is connected to the vehicle, the reduction of charge in the
hybrid battery (traction battery) will be suppressed to allow you to
use electricity from an external power source.
Charging will be conducted automatically after the Remote Air Condi-
tioning System is stopped.
■Before leaving the vehicle
Check the temperature setting of the air conditioning system.
The Remote Air Conditioning System will operate in accordance with
the temperature settings of the air conditioning system.
■Activating the Remote Air Conditioning System
Press and hold the to
operate the Remote Air Condi-
tioning System.
The system will shut off if a
door is opened.
The system can be stopped by
pressing the twice.
