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 9 )
●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 9 )
■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.

when the engine speed that is displayed may differ even when vehicle oper-
ation and driving conditions are the same.

■Headlight control sensor (if equipped)
■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30
seconds after a door is opened and closed if the “POWER” switch is
turned to ACCESSORY mode or turned off. (The lights turn off immedi-
ately if on the key is pressed after all the doors are locked.)
●When only the tail lights come on: The tail lights turn off automatically if
the “POWER” switch is turned to ACCESSORY mode or turned off and
the driver’s door is opened.
To turn the lights on again, turn the “POWER” switch to ON mode, or turn the
light switch off once and then back to or .
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
Air conditioning operation may also be
interrupted.

Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
●Engine speed and compressor operation controlled to restrict heating/
cooling capacity
●Fan speed restricted when automatic mode is selected
To i m p r o v e a i r c o n d i t i o n i n g p e r f o r m a n c e , p e r f o r m t h e f o l l o w i n g o p e r a t i o n s :

■When outside air temperature is below 32 °F (0 °C)
The cooling and dehumidification function may not operate even when
is pressed.
■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 r e d u c e p o t e n t i a l o d o r s f r o m o c c u r r i n g :
•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.

Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.
