■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decelera-
tion force can be obtained in conjunction with the recharging of the hybrid battery (trac-
tion battery).
●The accelerator pedal is released while driving with the shift position in D or B.
●The brake pedal is depressed while driving with the shift position in D or B.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop automati-
cally 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 10 miles (16 km). If the
hybrid battery becomes fully discharged and you are unable to start the hybrid system,
contact your Lexus dealer.

■After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is being driven by the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer. The EV indicator comes on when the vehicle is
driven using only the electric motor (traction
motor) or the gasoline engine is stopped.

●The standard battery life is 1 to 2 years. (The card key battery life is about a year and a
half.)
●If the battery becomes low, an alarm will sound in the cabin when the hybrid system
stops. ( →P. 5 4 6 )
●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 elec-
tronic key battery may be depleted. Replace the battery when necessary. ( →P. 5 0 2 )
• The smart access system with push-button start 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 3 ft. (1 m) of the
following electrical appliances that produce a magnetic field:
•TVs

Driving
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply engine brak-
ing.
• When the vehicle is driven at high speeds, compared to ordinary gasoline-fueled vehi- cles, the engine braking deceleration is felt less than that of other vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven contin uously in the B position, fuel efficiency will become low. Usu-
ally, select the D position.
■When driving with cruise control or dynamic radar cruise control activated
Even if switching the driving mode to sport mo de with the intent of enabling engine brak-
ing, engine braking will not activate because cruise control or dynamic radar cruise con-
trol will not be canceled.
■Automatically P position selection function
When the shift position is in a position other than P, pressing the power switch with the
vehicle stopped completely will cause the shift position to change to P automatically, and
then the power switch will turn off.
■If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt battery in
this situation. ( →P. 5 6 1 )
■After recharging/reconnecting the 12-volt battery
→P. 4 8 6
■Customization
Settings (e.g. Reverse warning buzzer) can be changed.
(Customizable features: →P. 5 9 1 )
WA R N I N G
■When driving on slippery road surfaces
Do not accelerate or shift the shift position suddenly.
Sudden changes in engine braking may cause th e vehicle to spin or skid, resulting in an
accident.
■For the shift lever
Do not remove the shift lever knob or use anything but a genuine Lexus shift lever
knob. Also, do not hang anything on the shift lever.
Doing so could prevent the shift lever from returning to position, causing unexpected
accidents to occur when the vehicle is in motion.
■P position switch
Do not press the P position switch while the vehicle is moving.
If the P position switch is pressed when driving at very low speeds (for example, directly
before stopping the vehicle), the vehicle may stop suddenly when the shift position
switches to P, which could lead to an accident.

■Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following precautions before recharging:
●If recharging with the 12-volt battery installed on the vehicle, be sure to disconnect the
ground cable.
●Make sure the power switch on the charger is off when connecting and disconnecting
the charger cables to the 12-volt battery.
■After recharging/reconnecting the 12-volt battery
●Unlocking the doors using the smart access system with push-button start may not be
possible 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 sys-
tem 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 before disconnect the 12-
volt battery. Take extra care when connecting the 12-volt battery if the power switch
mode prior to discharge is unknown.
●Restart the hybrid system, depress the brake
pedal, and confirm that it is possible to
shift into each shift position.
If the system will not start even after multiple attempts at all methods above, contact your
Lexus dealer.

When trouble arises
■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 sy stem 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.
■When the 12-volt battery is removed or discharged
●The hybrid system may not start. (→P. 4 8 6 )
●If the 12-volt battery discharges while the shift position is in P, it may not be possible to
shift the shift position to other positions. In this case, the vehicle cannot be towed with-
out lifting both front wheels because the front wheels will be locked. ( →P. 5 2 2 )
●When the 12-volt battery is reconnected, start the hybrid system and confirm that the
shift position can be changed to each position using the shift position indicator.
●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. 7 5 )
■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 certain electrical appli-
ances. 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 battery recharges automatically while
the hybrid system is operating.)
