Device) flashes.
Electrical leakage detection
function or self- diagnostic
function operates and power
is cut off
When the voltage is insufficient, the error
warning indicator may flash when there is
noise interference. Perform a reset and con-
nect to a proper power source. (P. 118)
If charging does not start, immediately stop
charging and contact your Toyota dealer.
Charging indicator does not illuminate, even though charging connector
is connected.
The plug is not properly con-
nected to the outletCheck whether the plug is properly con-
nected to the outlet.
Charging connector is not
securely connected to
charging inlet
Check the connection status of the charging
connector.
• When connecting the charging connec-
tor, make sure not to touch the latch
release button. Insert the charging con-
nector securely until you hear a click. The
charging connector may not be connected
correctly if the latch release button is
pressed while inserting.
• After connecting the charging connector,
check that the latch release button is not
pressed and the charging indicator is
turned on.
If the charging indicator does not illuminate,
even though the charging connector is
securely connected, there may be a mal-
function in the system. Immediately stop
charging and contact your Toyota dealer.
Hybrid battery (traction bat-
tery) is already fully chargedWhen the hybrid battery (traction battery) is
fully charged, charging is not performed.

■The meters and display illuminate when
The power switch is in ON mode.
■Adjusting the instrument cluster brightness (P. 194)
●The brightness levels that can be selected differ depending on whether the
tail lights are on and surrounding brightness levels, as shown in the table
below.
*: 22 levels of the brightness are displayed on the setting screen. However,
the brightness setting will be the brightest when other than 1st level (the
darkest) is selected. If other than 1st or 22nd level is selected, when the
tail lights are turned on in a dark place, the instrument cluster brightness
setting will be the selected level.
●If the taillights are illuminated in a dark environment, the instrument cluster
light dims. However, when the brightness of the instrument cluster is set to
minimum or maximum (1st or 22nd level of the instrument cluster bright-
ness), even if the taillights are illuminated, the instrument cluster light will
not dim.
■When disconnecting and reconnecting 12-volt battery terminals
The settings of the clock will be reset.
■Calendar setting
●Until the calendar setting is completed, the check screen is displayed every
time the power switch is turned to ON mode.
●After the calendar information is set, it can be changed in the “Meter Cus-
tomize” settings. (P. 248)

If calendar recording is interrupted due to
replacement of the 12-volt battery or 12-
volt battery discharge, etc., when the
power switch is turned to ON mode after
maintenance, the calendar setting check
screen is automatically displayed on the
multi-information display.
●If date information is not set, the electric-
ity and fuel consumption record cannot
be stored correctly. Also, the charging
schedule function can not operate prop-
erly. When the calendar setting check
screen is displayed, make sure to com-
plete the calendar setting. (P. 246)

Display contentsDetail
Hybrid System Indicator
A convenient Hybrid System Indicator is displayed.
Refer to P. 225 for details on how to read the Hybrid
System Indicator.
Current electricity consumption
When in EV/EV auto mode, the current electricity
consumption during driving is displayed.
• The mark indicates the total average electric-
ity consumption since last reset until it is reset
again.
• When “Electricity Consumption Reset” (P. 250)
is performed, the data of the total average elec-
tricity consumption is deleted and the mark is
reset to 0.
Current fuel consumption
When in HV mode, the current fuel consumption
during driving is displayed.
• The mark indicates the value displayed in the
average fuel consumption display (P. 213).
Switching the average fuel consumption display
also changes the position of the mark.
• When the average fuel consumption is reset, the
position of the mark is reset to 0.
Hybrid battery (traction battery) status
The same contents as the hybrid battery (traction
battery) status on the Hybrid System Indicator are
displayed. (P. 225)

■Eco score
The driving status for the following 3 situations are evaluated in 5
levels: Smooth start-off acceleration (“Eco-Start”), driving without
sudden acceleration (“Eco-Cruise”) and smooth stopping (“Eco-
Stop”). Each time the vehicle is stopped, a score result is displayed
out of a perfect score of 100 points.
Score result
“Eco-Start” status
“Eco-Cruise” status
“Eco-Stop” status
How to read the bar display:
*: For items not currently evaluated, the display reads 0.
●The Eco score is reset each time the vehicle starts off to start a new
evaluation.
●When the shift position is P, only the Eco score display area is
enlarged and displayed. When the shift position is shifted from P,
the display returns to normal.
●When the hybrid system stops, the current total score result and
advice on how to increase the score are displayed. (P. 196)
