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: -35C [-31F])
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.

7027-2. Steps to take in an emergency
UK_AURIS/AURIS_HV_EE (OM12F76E)
If the fan is not operating: 
Stop the engine immediately and contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
If the fan is operating: 
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
CAUTION
When inspecting under the hood of your vehicle
Observe the following precautions. 
Failure to do so may result in serious injury such as burns.
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts.
Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
NOTICE
When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
To prevent damage to the cooling system
Observe the following precautions:
Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
Do not use any coolant additive.
