2014 TOYOTA AURIS HYBRID cooling

4125-1. Using the air conditioning system and defogger
UK_AURIS/AURIS_HV_EE (OM12G88E)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 wind-
shield 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 button to the recirculated air mode. This is effec-
tive 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 is low
The dehumidification function may not operate even when is pressed.
When
is selected for the air outlets used
For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the position of the temperature adjust-
ment dial.
Ventilation and air conditioning odors
To let fresh air in, set the air conditioning system to the outside air mode.
During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with a Stop & Start system)
When the engine is stopped due to Stop & Start system operation, the air
conditioning cooling, heating and dehumidification functions turn off and only
ambient temperature air is blown, and there is a possibility that the blowing of
ambient temperature air will stop. To prevent the air conditioning system from
turning off, press the Stop & Start cancel switch to deactivate the system.

5026-3. Do-it-yourself maintenance
UK_AURIS/AURIS_HV_EE (OM12G88E)
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
When working on the engine compartment
Hybrid model: Make sure that the indicator on the power switch and the
“READY” indicator are both off.
Keep hands, clothing and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel or the 12-volt
battery. Fuel and 12-volt battery fumes are flammable.
Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system (except hybrid model):
Be sure the engine switch is off.
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. 523)
Vehicles with a smart entry & start system (except hybrid model):
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 523)
Hybrid model:
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 523)

Power control unit coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line.
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% deion-
ized 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 model: Visually check the radiator, hoses, engine coolant res-
ervoir caps, drain cock and water pump.
Hybrid model: 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 model)
Do not remove the engine coolant reservoir cap.
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 model)
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.
