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 lever in D or S.
The brake pedal is depressed while driving with the shift lever 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 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 rea-
son, 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 a 12-volt battery, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
If the shift lever is in N, the hybrid battery (traction battery) will not be charged.
Always shift the shift lever to P when the vehicle is stopped. When driving in
heavy traffic, operate the vehicle with the shift lever in D or S to avoid dis-
charging the battery.
Charging the 12-volt battery
P. 552 The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or the gasoline engine is
stopped.

Connect the jumper cables according to the following procedure:
Connect a positive jumper cable clamp to the exclusive jump start-
ing terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the posi-
tive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery terminal
on the second vehicle.
Connect the clamp at the other end of the negative cable to a solid,
stationary, unpainted metallic point away from the exclusive jump
starting terminal and any moving parts, as shown in the illustration.
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Open and close any of the doors of your vehicle with the power switch
off.
Maintain the engine speed of the second vehicle and start the hybrid
system of your vehicle by turning the power switch to ON mode.
Make sure the “READY” indicator comes on. If the indicator does not
come on, contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.3

Once the hybrid system has started, remove the jumper cables in the
exact reverse order from which they were connected.
Once the hybrid system starts, have the vehicle inspected at any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped
professional as soon as possible.
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
To prevent 12-volt battery discharge
Turn off the headlights and the audio system while the hybrid system is off.
Turn off any unnecessary electrical components when the vehicle is running at
a low speed for an extended period, such as in heavy traffic.
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the 12-volt battery
may discharge, and the hybrid system may be unable to start. (The 12-volt bat-
tery recharges automatically while the hybrid system is operating.)
When recharging or replacing the 12-volt battery
For vehicles with an alarm: Make sure that the key is not inside the vehicle
when recharging or replacing the 12-volt battery. The key may be locked in the
vehicle if the alarm is activated. (P. 98)
In some cases, it may not be possible to unlock the doors using the smart entry
& start system when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
The hybrid system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a mal-
function.
The power switch mode is memorized by the vehicle. When the 12-volt battery
is reconnected, the system will return to the mode it was in before the 12-volt
battery was discharged. Before disconnecting the 12-volt battery, turn the
power switch off.
If you are unsure what mode the power switch was in before the 12-volt battery
discharged, be especially careful when reconnecting the 12-volt battery.

NOTICE
When handling jumper cables
When connecting the jumper cables, ensure that they do not become entangled
in the cooling fans or belt.
Exclusive jump starting terminal
The exclusive jump starting terminal is intended to charge the 12-volt battery
on your vehicle from another vehicle in an emergency. Do not use the exclusive
jump starting terminal to jump start another vehicle.
