tery (traction battery).

●

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

●

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 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.

●

If the shift lever is in N, the hybrid battery (traction battery) will not be charged.

Always put the shift lever in P when the vehicle is stopped. When driving in heavy

traffic, operate the vehicle with the shift lever in D or S to avoid discharging the bat-

tery.
