◆When stopped/during start off
The gasoline engine stops
* when the vehicle is stopped. During
start-off, the electric motor (traction motor) drives the vehic le. At
slow speeds or when traveling down a gentle slope, the engine i s
stopped
* and the motor is used.
When the shift lever is in N, the hybrid battery (traction batt ery) is
not being charged.
*: When the hybrid battery (traction battery) requires charging o r the engine
is warming up, etc., the gasoline engine will not automatically stop.
( P. 78)
◆During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybr id battery (traction battery) as nec-
essary.
◆When accelerating sharply
The power of the hybrid battery (traction battery) is added to that of
the gasoline engine via the ele ctric motor (traction motor).
◆When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a pow er
generator, and the hybrid battery (traction battery) is charged.
When the gasoline engine is off while driving, a sound is produ ced to
warn pedestrians, people riding bicycles or other people and ve hicles
in the surrounding area that the vehicle is approaching. The pi tch of
the sound adjusts according to v ehicle speed. When vehicle spee d is
approximately 22 mph (35 km/h) or more, the warning system turn s
off.

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the rech arging of the
hybrid battery (traction battery).
● The accelerator pedal is released with the shift lever in D or B.
● The brake pedal is depressed with the shift lever in D or B.
■ EV drive indicator lamp
■ 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
The EV drive indicator lamp comes on
when the vehicle is driven using only the
electric motor (traction motor) or the gas-
oline engine is stopped.
This indicator lamp will also be dis-
played when “ECO Score” or “ECO
Savings” is selected. ( P. 105)

Charging the hybrid batt ery (traction battery)
As the gasoline engine charges the hybrid battery (traction bat tery), the bat-
tery does not need to be charged from an outside source. Howeve r, i f t h e
vehicle is left parked for a long time the hybrid battery (trac tion 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). I f the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact your Toyota dealer.
■ Charging the 12-volt battery
P. 525
■ After the 12-volt battery has discharged or when the terminal h as been
removed and installed during exchange, etc.
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
Toyota dealer.

(Cruising range)
Displays the estimated maximum distance that can be driven with
the quantity of fuel remaining. • This distance is computed base d on your average fuel consump-
tion. As a result, the actual di stance that can be driven may differ
from that displayed.
• When only a small amount of fuel is added to the tank, the dis -
play may not be updated.
When refueling, turn the power swi tch off. If the vehicle is refu-
eled without turning the power switch off, the display may not be
updated.

Key battery depletion
Vehicles without a smart key system
If the wireless remote control function does not operate, the b attery may be
depleted. Replace the battery when necessary. ( P. 451)
Vehicles with a smart key system
● The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin wh en the hybrid
system stops. ( P. 503)
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( P. 451)
• The smart key system or the wireless remote control does not o perate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.

Maintenance and care
PRIUS c_U■
After recharging/reconnecting the 12-volt battery (vehicles wit h a smart
key system)
● Unlocking the doors using the smart key system may not be possi ble imme-
diately after reconnecting the 12-volt battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the do ors.
● Start the hybrid system with the power switch in ACCESSORY mode . The
hybrid system 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-vol t battery is
reconnected, the vehicle will return the power switch mode to t he status it
was in before the 12-volt battery was disconnected. Make sure t o turn off
the power before disconnect the 12-volt battery. Take extra car e when con-
necting the 12-volt battery if the power switch mode prior to d ischarge is
unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
