1-1. Hybrid system
Regenerative braking
■
The motor generator converts kinetic energy to electric energy when:
The accelerator pedal is released.
●
The brake pedal is depressed with the shift lever in "D" or "S".
●
Conditions in which the gasoline engine may not stop
■
The gasoline engine starts and stops automatically. However, it may not stop auto-
matically in the following conditions:
During gasoline engine warm-up
●
During hybrid battery (traction battery) charging
●
During low or high hybrid battery (traction battery) temperature
●
Charging the 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 will slowly discharge. For this rea-
son, 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 becomes fully discharged and
you are unable to jump-start the vehicle with the 12 volt battery, contact your
Lexus dealer.
If the shift lever is in "N", the hybrid battery (traction battery) will not be
●
charged. When driving in heavy traffic, operate the vehicle with the shift lever in
"D" or "S" to avoid discharging the battery.
