◆When stopped/during start off
The gasoline engine stops* when the vehicle is stopped. During
start off, the electric motor (traction motor) drives the vehicle. At
slow speeds or when traveling down a gentle slope, the engine is
stopped* and the electric motor (traction motor) is used.
When the shift lever is in N, the hybrid battery (traction battery) is
not being charged.
*: When the hybrid battery (traction battery) requires charging or the engine
is warming up, etc., the gasoline engine will not automatically stop.
( P. 77)
◆During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid battery (traction battery) as nec-
essary.
◆When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the
hybrid battery (traction battery) is added to that of the gasoline
engine via the electric motor (traction motor).
◆When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a power
generator, and the hybrid battery (traction battery) is charged.

■Regenerative braking
In the following situations, kinetic ener gy 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 B.
● The brake pedal is depressed while driving with the shift lever 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
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 bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time t he hybrid battery (traction 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 (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.

■ Conditions affecting operation (wireless remote control)
The wireless remote control function may not operate normally in the follow-
ing situations:
● When the wireless key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise

Driving
YARIS_HV_OM_Europe_OM52G76E
*: To improve fuel efficiency and reduce noises, set the shift lever in D for
normal driving.
Suitable for improving the fuel economy, because the torque corre-
sponding to the accelerator pedal depression amount can be gener-
ated more smoothly than it is in normal conditions and the operation
of the air conditioning system (heating/cooling) will be minimized.
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.
■ Operation of the air conditioning 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. 298) To improve air
conditioning performance, adjust the temper ature setting or 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 fr om discharging, avoid putting the shift
lever in N for an extended period of time.

■Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, obser ve the following precautions before
recharging:
● If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
■ When disconnecting the 12-volt battery terminals
Always disconnect the negative (-) terminal first.
■ After recharging/reconnecting the 12-volt battery
● Unlocking the doors using entry function of the smart entry & start system
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.
● Vehicles with a smart entry & start system: 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 nor-
mally from the second attempt.
● Vehicles with a smart entry & start system: 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 bat-
tery 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.
If the system will not start even after multiple attempts, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped professional.
