321-1. Hybrid system
■
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. ●
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●
When the temperature of the hybrid batt ery (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 ba ttery will slowly discharge. For this rea-
son, be sure to drive the vehicle at least once every few months for at least 30
minutes. 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 discharg-
ing the battery.■
After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not st op even if the vehicle is running on the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.

When driving When stopping the hybrid system with the shift lever in a position other than P
If the hybrid system is stopped with the shift lever in a position other than
P, the “POWER” switch will not be turned off but instead be turned to
ACCESSORY mode. Perform the following procedure to turn the switch
off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that the indicator on the “POWER” switch is illuminated in
amber and then press the “POWER” switch once.

Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or ON mode with
the hybrid system not operating for more than 20 minutes (ACCESSORY mode)
or one hour (ON mode), the “POWER” switch will automatically turn off. However,
this function cannot entirely prevent 12-v olt battery discharge. Do not leave the
vehicle with the “POWER” switch in ACCESSORY or ON mode for long periods
of time when the hybrid system is not operating.■
Operation of the “POWER” switch
When operating the “POWER” switch, one short, firm press is enough. If the switch
is pressed improperly, the hybrid system may not start or the “POWER” switch
mode may not change. It is not necessary to press and hold the switch.■
