■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decel-
eration force can be obtained in conjunction with the recharging of the hybrid bat-
tery (traction battery).
●The accelerator pedal is released while driving with the shift position in D or S.
●The brake pedal is depressed while driving with the shift position in D or S.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops auto matically. However, it may not stop auto-
matically in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (t raction 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-v olt battery, contact your Lexus dealer.
●If the shift lever is in N, the hybrid ba ttery (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 le ver in D or S to avoid discharging the bat-
tery.
■Charging the 12-volt battery
