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 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 becomes fully discharged and you are unable

to jump-start the vehicle with the 12-volt battery, contact your Lexus dealer.

The gasoline engine may not stop even if the vehicle is running on the hybrid battery

(traction battery). If this continues for a few days, contact your Lexus dealer.
