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.

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 operation and driving conditions are the same.
Brightness of the instrument cluster light
If the headlight switch is turned to ON while the surrounding area is dark, the
instrument cluster lights will dim.
When disconnecting and reconnecting 12-volt battery terminals
The average fuel consumption and cruising range will be reset.
NOTICE
To prevent damage to the engine and its components
The engine may be overheating if the high coolant temperature warning light
comes on or flashes. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 528)
The trip information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.

338 3-1. Using the air conditioning system and defogger
PRIUS +_OM_OM47821E_(EE)
Air conditioning odors
During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
Customization
Settings (e.g. switching between outside air and recirculated air mode linked
to “AUTO” switch operation) can be changed.
(Customizable features P. 554)
CAUTION
To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
