◆“Eco-Diary”
The history of the average electricity consumption, air conditioning
system load ratio (“A/C Load Ratio”)
*, distance traveled and aver-
age fuel consumption can be displayed in a table according to day
(“Daily”) or month (“Monthly”) units.
*: It indicates the percentage of the electricity consumed from the hybrid
battery (traction battery) that is consumed by the air conditioning sys-
tem.

■Operating switches of the air conditioning system operation panel
●The pop-up display function that displays when the air conditioning settings
are changed using the air conditioning system switches can be turned off in
the “Meter Customize” settings. (P. 260)
■Eco score (A/C score)
●The setting status of the following air conditioning system functions are
reflected in the score.
• Temperature setting
• Fan speed setting
• Outside air and recirculated air modes
• “A/C” button
• Front seat concentrated airflow mode (S-FLOW)
• “CLIMATE PREFERENCE”
●The Eco score (A/C score) is evaluated according to the ambient tempera-
ture and cabin temperature. Accordingly, even if the same settings are
always used for the air conditioning system, the evaluation will change
according to such factors as the season and weather.
●When the air conditioning system is not being used or the airflow mode is
set to or , the Eco score (A/C score) is not evaluated. (While the
air conditioning system is not evaluated, its usage status is not reflected in
the total Eco score result.)
●The Eco score (A/C score) is a function that helps select an air conditioning
system setting which reduces electricity and fuel consumption, not a func-
tion that satisfies both comfortability and low fuel consumption. ●When the air conditioning system
switches are operated to change the air
conditioning settings while a screen
other than the air conditioning system
settings screen is displayed on the multi-
information display, a pop-up display for
the air conditioning settings contents is
displayed. However, air conditioning
system settings cannot be changed on
the pop-up display.

Use the displayed average fuel consumption as a reference.
The image is an example only, and may vary slightly from actual
conditions.
■Updating the history data
Update the latest fuel consumption by selecting “Update” to measure the cur-
rent fuel consumption again.
■Resetting the data
The fuel consumption data can be deleted by selecting “Clear”.
■Cruising range
Displays the estimated maximum distance that can be driven with the quan-
tity of fuel remaining.
This distance is computed based on your average fuel consumption. As a
result, the actual distance that can be driven may differ from that displayed.

■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
●Install tire chains on the front tires only. Do not install tire chains on the rear
tires.
●Install tire chains on front tires as tightly as possible. Retighten chains after
driving 0.5 - 1.0 km (1/4 - 1/2 mile).
●Install tire chains following the instructions provided with the tire chains.
■Consumption of fuel and electricity
In cold temperatures, resistance of the parts of a vehicle (transmission, tires,
etc.) generally increases, resulting in increase of energy consumption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of this vehicle is also likely to become
worse in cold temperatures.

5766-1. Using the air conditioning system and defogger
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
■Switching between outside air and recirculated air modes
Press .
The mode switches between outside air mode and recirculated air mode
each time is pressed.
The indicator illuminates when the recirculated air mode is
selected.
■
Blower customization
Fan speed setting during the automatic mode operation can be cus-
tomized.
To change the fan speed setting mode, press .
Each time is pressed, the fan speed setting mode changes as
follows.
“NORMAL”  “ECO”  “FAST”  “NORMAL”
When “ECO” is displayed on the air conditioning screen, the air condi-
tioning is controlled with low fuel consumption prioritized such as reduc-
ing fan speed, etc.
When “FAST” is displayed on the screen, fan speed will be increased.

Maintenance and care
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
■Cleaning the air intake vents and filters
●Dust on the air intake vents or filters may interferes cooling of the hybrid bat-
tery (traction battery) and results in poor electricity and fuel consumption.
Clean the air intake vents and filters periodically.
●If continuing to drive the vehicle with “Maintenance required for Traction bat-
tery cooling parts See owner’s manual” shown on the multi-information dis-
play, the hybrid battery (traction battery) may overheat, leading to
decreasing in distance that can be driven using the electric motor. It may
cause poor electricity and fuel consumption or a malfunction. If the warning
message is shown, clean the air intake vents and filters immediately.
●Improper handling may result in damage to the grille or filters. If you have
any concerns about cleaning the filters, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
●If the warning message on the multi-information display does not disappear
after cleaning the filters, have the vehicle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Timing of cleaning filters differs depending on the use environment of the
vehicle.
