■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 ga soline 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
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 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 lever in D or S to avoid discharging the bat-
tery.
●To help prevent the 12-volt battery from becoming discharged, drive the vehicle at
least once a month, and operate the accessories only when the “READY” indicator
is on. When parking the vehicle, make sure the doors and trunk are closed and all
lights are turned off.
The EV indicator comes on when the vehicle
is driven using only the electric motor (trac-
tion motor) or the gasoline engine is stopped.

■Charging the 12-volt battery
 P. 609
■After the 12-volt battery has discharged or has been changed or removed
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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to move.
For safety, apply the parking brake and make sure to shift the shift lever to P when
parked.
The following sounds or vibrations may occur when the hybrid system is operating
and are not a malfunction:

seats when the hybrid system starts or stops.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the hybrid transmission when the hybrid system starts
or stops.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the accelerator pedal is
released or the brake pedal is depressed.
●Vibration may be felt or sounds may be heard when the gasoline engine starts or
stops.
●Cooling fan sounds may be heard from the air intake vents on the package tray.
■Hybrid battery (traction battery) cooling
The air conditioning system may operate automatically to cool the hybrid battery
(traction battery).
■Maintenance, repair, re cycling, and disposal
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional regarding maintenance, repair, recycling and disposal. Do not
dispose of the vehicle yourself.
■Customization
