Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (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 automatically. However, it may not stop
automatically 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 bat-
tery 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 dis-
charge. For this reason, be sure to drive the vehicle at least once every few
months for at least 30 minutes or 16 km (10 miles). If the hybrid battery
becomes fully discharged and you are unable to jump-start the vehicle with
the 12-volt battery, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
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 battery.
Charging the 12-volt battery
P. 9 1 2 The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.

year and a half.)
If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 867)
As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms
indicate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 777)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appliances that produce a magnetic field:

Maintenance and care
GS450h_300h_OM_OM30D53E_(EE)
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:
If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
After recharging/reconnecting the 12-volt battery
The hybrid system may not start. Follow the procedure below to initialize
the system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the hybrid system.
Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the doors.
Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate normally from the second attempt.
The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off
the power switch before disconnect the 12-volt battery. Take extra care
when connecting the 12-volt battery if the power switch mode prior to dis-
charge is unknown.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
