After the 12-volt battery has discharged 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 any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. For safety, apply the parking brake and make sure to shift the shift
lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
Motor sounds may be heard from the engine compartment.
Sounds may be heard from the hybrid battery (traction battery) under the
rear seats when the hybrid system starts or stops.
Sounds from the hybrid system may be heard when the back door is
open.
Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
Engine sounds may be heard when accelerating sharply.
Sounds may be heard due to regenerative braking when the brake pedal
is depressed and accelerator is loosened.
Vibration may be felt when the gasoline engine starts or stops.
Cooling fan sounds may be heard from the air intake vent on the side of
the lower part of the rear left seats.
Maintenance, repair, recycling, and disposal
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.

When driving

Shift position purpose
*: To improve fuel efficiency and reduce noises, set the shift lever in the D
position for normal driving.
Selecting Eco drive mode
Suitable for improving the fuel economy, because the torque cor-
responding to the accelerator pedal depression amount can be
generated 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.

254 2-1. Driving procedures
YARIS_F (including HV)_WE_52C79E
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. 368) To improve air
conditioning performance, adjust the temperature 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 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. 616
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.

Adjusting the settings
To adjust the fan speed, turn the fan speed control dial clock-
wise (increase) or counterclockwise (decrease).
Turning the dial to “0” turns off the fan.
Vehicles without a cooling and dehumidification function on/off
button:
Turn the temperature control dial clockwise to increase the
temperature.
Vehicles with a cooling and dehumidification function on/off
button:
To adjust the temperature setting, turn the temperature control
dial clockwise (warm) or counterclockwise (cool).
If is not pressed, the system will blow ambient temperature
air or heated air.
To select the air outlets, set the air outlet selector dial to the
desired position.
The positions between the air outlet selectors shown below can also
be selected for more delicate adjustment.
Defogging the windshield
Set the air outlet selector dial to
position.
Set the outside/recirculated air
mode dial to outside mode if recir-
culated air mode is used.

Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
If you turn off, the windows may fog up more easily.
The windows may fog up if the recirculated air mode is used.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode dial to the recirculated air mode. This is effective
in preventing outside air from entering the vehicle interior. During cooling
operation, setting the recirculated air mode will also cool the vehicle interior
effectively.
When the indicator light on goes off by itself (vehicles with a
cooling and dehumidification function on/off button)
Press to turn off the dehumidification function and turn it on again.
There may be a problem in the air conditioning system if the indicator light
goes off again. Turn the air conditioning system off and have it inspected by
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
When the outside temperature falls to nearly 0°C (32°F) (vehicles with a
cooling and dehumidification function on/off button)
The dehumidification function may not operate even when is
pressed.
