■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.
● The brake pedal is depressed with the shift lever in D or B.
■ EV indicator
■ Conditions in which the g asoline 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
The EV indicator comes on when driving
the vehicle using only the electric motor
(traction motor).

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 dis-
charge. 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 bat-
tery becomes fully discharged and you are unable to jump-start the vehi-
cle with the 12-volt battery, contact your Toyota 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 B to avoid discharging the battery.
■ Charging the 12-volt battery
P. 463
■ After the 12-volt battery has di scharged 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 your Toyota
dealer.

Before driving
■
System maintenance
The vehicle has a maintenance-free type alarm system.
■ Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure
of the following:
●Nobody is in the vehicle.
● The windows and moon roof are closed before the alarm is set.
● No valuables or other personal items are left in the vehicle.
■ Triggering of the alarm
The alarm may be triggered in the following situations.
(Stopping the alarm deactivates the system.)
■ Alarm-operated door lock
●When the alarm is operating, the doors are locked automatically to pre-
vent intruders.
● Do not leave the key inside the vehicle when the alarm is operating, and
make sure the key is not inside the vehicle when recharging or replacing
the 12-volt battery.
●A person inside the vehicle opens a
door, the trunk or hood.
● The 12-volt battery is recharged or
replaced when the vehicle is locked.

■Operation of the air conditio ning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. ( P. 232) To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ When in heavy traffic
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid putting the shift
lever in N for an extended period of time.
■ If the shift lever cannot be shifted from P
P. 456
CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ Selecting Eco drive mode
When the vehicle is driven in Eco drive mode, vehicle driving
force and operation of the air co nditioning system (heating/cool-
ing) is controlled to improve fuel efficiency.
Eco drive mode
When eco drive mode is turned
on, the “ECO MODE” indicator
will come on.
Pressing the “ECO MODE”
switch again turns eco drive
mode off.

■Automatic light off system
When the light switch is in : The headlights and tail lights turn off 30
seconds after the “POWER” switch is turned to ACCESSORY mode or
turned off and a door is opened and closed. (The lights turn off immediately if
on the key is pressed twice after all the doors are closed.)
To turn the lights on again, turn the “POWER” switch to ON mode, or turn the
light switch off once and then back to or .
If any of the doors or trunk lid is kept open, the lights automatically turn off
after 20 minutes.
■ Light reminder buzzer
A buzzer sounds when the “POWER” switch is turned off or turned to
ACCESSORY mode and the driver's door is opened while the lights are
turned on.
■ 12-volt battery-saving function
In order to prevent the vehicle 12-volt battery from discharging, if the head-
lights and/or tail lights are on when the “POWER” switch is turned off the 12-
volt battery saving function will operate and automatically turn off all the
lights after approximately 20 minutes.
When the “POWER” switch is turned to ON mode, the 12-volt battery-saving
function will be disabled.
When any of the following are performed, the 12-volt battery-saving function
is canceled once and then reactivated. All the lights will turn off automatically
20 minutes after the 12-volt battery-saving function has been reactivated:
●When the headlight switch is operated
● When a door is opened or closed
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. Light sensor sensitivity) can be changed.

■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
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.
■ Exterior
Make sure that the 12-volt battery terminals are not corroded
and that there are no loose c onnections, cracks, or loose
clamps.
