228 2-1. Driving procedures
PRIUS +_OM_OM47821E_(EE)
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. 226) To improve air
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.
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.

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 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.
Switching the drive mode when in EV drive mode

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

246 2-2. Instrument cluster
PRIUS +_OM_OM47821E_(EE)Press and hold the “DISP” button for 1 second or more to
complete the setup.
If setup is not completed by pressing and holding the “DISP” button
for 1 second or more, or if nothing is operated within approximately
10 seconds, the screen will return and the settings will be lost.
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 or EV drive mode. (P. 221, 226)
The vehicle speed is approximately 130 km/h (80 mph) or higher.
Eco Driving Indicator Light can be set to activated or deactivated.
(P. 245)
Remaining hybrid battery (traction battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or electricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may
not reach the highest level (level 8). However, this does not indicate a mal-
function.
