YARIS_F (including HV)_WE_52C79ERight and left side outlets
Direct air flow to the left or right,
up or down.
Open the vent.
Close the vent.
Operation of the air conditioning system in Eco drive mode (hybrid
vehicle)
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
Heating/cooling capacity is restricted.
Outside/recirculated air mode automatically switch depending on the
temperature setting or the inside temperature.
Fan speed restricted when automatic mode is selected.
To improve air conditioning performance, perform the following operations:
Adjust the fan speed or the setting temperature.
Turn off Eco drive mode.
Customization
The air conditioning control of Eco drive mode can be changed to the same
setting as that used in normal drive mode.

Using the automatic mode
Fan speed is adjusted automatically in according to the temperature setting
and the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after
is pressed.
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
outside/recirculated air mode button 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.
Outside/recirculated air mode may automatically switch depending on
the temperature setting or the inside temperature.
When the outside temperature falls to nearly 0C (32F)
The dehumidification function may not operate even when is
pressed.

CAUTION
When working near the electric cooling fan or radiator grille
Except hybrid vehicle
Vehicles without a smart entry & start system:
Be sure the engine switch is in the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 481)
Vehicles with a smart entry & start system:
Be sure the “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fan may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. (P. 481)
Hybrid vehicle
Vehicles without an electronic key:
Be sure the engine switch is in the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 481)
Vehicles with an electronic key:
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 481)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.

Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Minimum temperature: -35C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
If the coolant level drops within a short time of replenishing
Except hybrid vehicle: Visually check the radiator, hoses, engine coolant res-
ervoir cap, drain cock and water pump.
Hybrid vehicle: Visually check the radiator, hoses, engine/power control unit
coolant reservoir caps, drain cock and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
CAUTION
When the engine is hot (except hybrid vehicle)
Do not remove the radiator cap (gasoline engine), or the engine coolant res-
ervoir cap (diesel engine).
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
When the hybrid system is hot (hybrid vehicle)
Do not remove the engine/power control unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
