Regenerative braking

Conditions in which the gasoline engine may not stop
■
The gasoline engine starts and stops automatically. However, it may not stop automati-
cally in the following conditions:
During gasoline engine warm-up
●
During hybrid battery (traction battery) charging
●
When the temperature of the hybrid battery (traction battery) is high or low
●
When the heater is switched on

Charging the hybrid battery (traction battery)
■
As the gasoline engine charges the hybrid battery (traction battery), the battery does not
need to be charged from an outside source. However, if the vehicle is left parked for a
long time the hybrid battery (traction battery) will slowly discharge. For this reason, be
sure to drive the vehicle at least once every few months for at least 30 minutes or 10
miles (16 km). If the hybrid battery (traction battery) becomes fully discharged and you
are unable to start the hybrid system, contact your Lexus dealer.
Charging the 12-volt battery
■
→P. 531
After the 12-volt battery has discharged or when the terminal has been removed and
■
installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.
