2-2. Charging
■Capacity reduction of the hybr id battery (traction battery)
The capacity of the hybrid battery (traction battery) will decline gradually
when the hybrid battery (traction battery) is in use. The rate at which it
declines will differ in accordance with environmental condition s and the way
in which the vehicle is used. Observing the following can help suppress bat-
tery capacity decline.
● Avoid parking the vehicle in areas with a high temperature unde r direct sun-
light when the hybrid battery (traction battery) is fully charged.
● Avoid accelerating and decelerating frequently and suddenly when EV driv-
ing.
● Avoid frequent driving near the top speed for EV driving. ( P. 93)
● Leave a low level of charge in the hybrid battery (traction bat tery) when
leaving the vehicle undriven for a long period of time.
After confirming that EV mode has switched to HV mode, turn the power
switch off.
● Use the charging timer function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting
off. ( P. 154)
Also, if the hybrid battery (traction battery) capacity reduces , the distance that
can be driven in EV mode decreases. However, vehicle performanc e does
not significantly become worse.
■ When the remaining charge of the hybrid battery (traction battery) is low
after charging
In the following situations, the remaining charge of the hybrid battery (traction
battery) after charging completes may be less than normal in or der to protect
the system (the EV driving range after the battery is fully charged may be
shorter).
*
● Charging is carried out when the outside temperature is low or high
● Charging is carried out immediately after high-load driving or in extreme
heat
When none of the above situations apply and there is a drastic drop in the
remaining charge of the hybrid battery (traction battery) after charging com-
pletes, have the vehicle inspected by your Toyota dealer.
*: When this occurs, even if the remaining charge display of the hybrid battery
(traction battery) shows that it is fully charged, the remainin g charge rapidly
decreases faster than normal.
■ Certification
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference
that may cause undesired operation.

2-2. Charging
Remove the plug from the out-
let when the charging equip-
ment will not be used for a
prolonged period of time.
Hold the body of the plug when
removing.
Make sure to put the cable away
immediately after disconnecting.
(P. 152)
When leaving the plug inserted, inspect the plug and connector once a
month to check if dirt or dust has accumulated.
■ Charging time
P. 131
■ Safety function
If the latch release button is pressed, charging will not begin even if the
charging cable is connected.
Also, charging will be stopped if the latch release button is pressed and held
for several seconds during charging. When restarting charging, reinsert the
charging connector after pulling it out, and check that the charging indicator
illuminates.
■ When the outside tempe rature is low or high
The level shown on the remaining charge display ( P. 224) may drop slightly
when the power switch is turned to ON mode, even if charging ha s been com-
pleted and the hybrid battery (traction battery) is fully charg ed. However, this
does not indicate a malfunction.
■ Charging time may increase
P. 132
■ While charging
When the power switch is turned to ON mode and the energy monitor dis-
plays, the charging connector is displayed on the energy monito r and the flow
of electricity during charging is displayed ( P. 216). Also, when the charging
connector is locked, is displayed.

■The meters and display illuminate when
The power switch is in ON mode.
■ Adjusting the instrume nt cluster brightness (P. 190)
● 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 scree n. 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 select ed, when the
tail lights are turned on in a dark place, the instrument clust er brightness
setting will be the selected level.
● If the taillights are illuminated in a dark environment, the in strument cluster
light dims. However, when the brightness of the instrument clus ter is set to
minimum or maximum (1st or 22nd level of the instrument cluster bright-
ness), even if the taillights are illuminated, the instrument c luster 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 di splayed 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. 241)

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
