Maintenance and care
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
Except 1AD-FTV engine
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line.
1AD-FTV engine

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.

6867-2. Steps to take in an emergency
UK_AURIS/AURIS_HV_EE (OM12E33E)
Have the vehicle inspected at the nearest any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional
as soon as possible.
Overheating
If you observe the following, your vehicle may be overheating:
Vehicles without a multi-information display: The high engine coolant tem-
perature warning light comes on or a loss of power is experienced.
Vehicles with a multi-information display: The high engine coolant tempera-
ture gauge enters the red zone or a loss of power is experienced.
Steam comes out from under the hood.
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 away from the fans, etc. while the engine is oper-
ating.
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 commercially available coolant additives.

Overheating
If you observe the following, your vehicle may be overheating:
The high engine coolant temperature is shown on the multi-information dis-
play or a loss of power is experienced.
“Hybrid System Overheat” is shown on the multi-information display.
Steam comes out from under the hood.
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 away from the fans, etc. while the hybrid system
is operating.
For vehicles with a hybrid system, there are times when the gasoline
engine automatically starts to run or the cooling fans suddenly start to
operate. Do not touch or approach the rotating parts of the belt or fans.
Doing so may lead to fingers, clothes or tools getting caught, resulting in
injury.
Do not loosen the coolant reservoir caps while the hybrid system and radi-
ator are hot.
High temperature steam or coolant could spray out.
NOTICE
When adding engine/power control unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently.
Adding cool coolant to a hot hybrid system too quickly can cause damage to
the hybrid system.
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 commercially available coolant additives.
