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.
