■Capacity reduction of the hybrid 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 conditions 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 under 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. 1 0 4 )
●Leave a low level of charge in the hybrid battery (traction battery) 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 schedule function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting off.
(P. 176)
Also, if the hybrid battery (traction battery) capacity reduces, the distance that
can be driven in EV mode decreases. However, vehicle performance 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 order 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 any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
*: When this occurs, even if the remaining charge display of the hybrid battery
(traction battery) shows that it is fully charged, the remaining charge rapidly
decreases faster than normal.
■When the charging amount sent to the hybrid battery (traction battery)
decreases
When the amount of power supplied by the charger is low or operation of the
“Traction Battery Heater”, etc., reduces the charging power sent to the hybrid
battery (traction battery), the charging amount sent to the hybrid battery (trac-
tion battery) may decrease.
