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. 507)
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. 507)
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. 507)

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.

Maintenance and care
Check the radiator, condenser and intercooler and clear away any for-
eign objects.
If any of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
NOTICE
When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
Radiator, condenser and intercooler
CAUTION
When the engine is hot (except hybrid model)
Do not touch the radiator, condenser or intercooler as they may be hot and
cause serious injuries, such as burns.
When the hybrid system is hot (hybrid model)
Do not touch the radiator or condenser as they may be hot and cause seri-
ous injuries, such as burns.

6857-2. Steps to take in an emergency
UK_AURIS/AURIS_HV_EE (OM12E33E)

When trouble arises
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam subsides and
then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the instrument
panel) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radia-
tor) for any leaks.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail-
able. (P. 709)

model)
