Maintenance and care
UK_AURIS_HV_EE
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
Keep hands, clothing, and tools away from the moving fan.
Be careful not to touch the engine, power control unit, 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 or rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
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, see a doctor.
When working near the electric cooling fan or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. (P. 379)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, 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.
Coolant selection
Only use “Toyota Super Long Life Coolant” or 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. (Enabled: -35C [-31F])
For more details about coolant, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
CAUTION
When the hybrid system is hot
Do not remove the coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing burns or other injuries.
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 damage to parts or paint.

Maintenance and care

Radiator and condenser
Check the radiator and condenser and clear any foreign objects.
If any of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
Washer fluid
If the fluid level is extremely low
add washer fluid.
Raise the cap keeping your finger
pressed down on the hole in the
center and check the fluid level in
the tube.
CAUTION
When the hybrid system is hot
Do not touch the radiator and condenser as they may be hot and may cause
burns.
CAUTION
When refilling the washer fluid
Do not refill the washer fluid when the hybrid system is hot or operating, as
the washer fluid contains alcohol and may catch fire if spilled on the hybrid
system etc.

480 5-2. Steps to take in an emergency
UK_AURIS_HV_EECheck to see if the cooling fans are operating.
If the fans are operating:
Wait until the high engine coolant temperature warning light
goes off and then stop the hybrid system.
If the fans are not operating:
Stop the hybrid system immediately and call any authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.
After the hybrid system has
cooled down sufficiently, check
the engine coolant level and
inspect the radiator core (radia-
tor) for any leaks.
If necessary, add engine coolant
up to the “FULL” line.
Water can be used in an emer-
gency measure if engine coolant
is unavailable. (P. 496)
