●Situations where the shift position will automatically change to N:
•When the P position switch is pressed while the vehicle is running.*1
•When an attempt is made to select the R position by moving the shift
lever when the vehicle is moving forward.*2
•When an attempt is made to select the D position by moving the shift
lever when the vehicle is moving in reverse.*3
•When an attempt is made to change the shift position from R to B by
moving the shift lever.
*1:Shift position may be changed to P when driving at extremely low
speeds.
*2:Shift position may be changed to R when driving at low speeds.
*3:Shift position may be changed to D when driving at low speeds.
■Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift
position is in R.
■Automatically P position selection function
When the shift position is in a position other than P, pressing the “POWER”
switch with the vehicle stopped completely will cause the shift position to
change to P automatically, and then the “POWER” switch will turn off.
■If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. (→P. 5 9 4 )

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.

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.

■Eco Driving Indicator Light
Eco Driving Indicator Light will turn on when driving power is lower than the
upper limit of Eco driving. It will turn off when the acceleration exceeds the
Eco driving accelerator upper limit or when the vehicle is stopped.
Eco Driving Indicator Light will not operate in the following conditions:
●The shift position is anything other than D.
●The driving mode is set to power mode. (→P. 2 4 7 )
●The vehicle speed is approximately 80 mph (130 km/h) or higher.
Eco Driving Indicator Light is also displayed when 5-minute consumption, 1-
minute consumption or monthly fuel consumption record is displayed.
Eco Driving Indicator Light can be set to activated or deactivated. (→P. 2 7 7 )
■Hybrid System Indicator display when in EV mode
The movement of the bar in response to the operation of the accelerator
pedal may differ in accordance with the status of the hybrid battery (traction
battery). However, this does not indicate a malfunction.
After switching the “POWER” switch to
ON mode, “welcome to PRIUS” is dis-
played while system operation is
checked. When the system check is com-
plete, the normal screen will return.

■Display settings can be changed when
The vehicle speed is less than approximately 5 mph (8 km/h).
■Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc. There are times
when the engine speed that is displayed may differ even when vehicle oper-
ation and driving conditions are the same.
■When the 12-volt battery is disconnected
The following data will be reset.
●Average fuel consumption
●Distance to empty
●Average vehicle speed

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
•Engine oil
•Engine/power control unit coolant
•Washer fluid
●Have a service technician inspect the condition of the 12-volt
battery.
●Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.

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.
