Maintenance and care
■If the coolant level drops within a short time of replenishing
Visually check the radiators, hoses, engine/power control unit coolant reser-
voir caps, drain cock and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.
Check the radiator and condenser and clear away any foreign obj ects.
If either of the above parts is extremely dirty or you are not sure of
their condition, have your vehicle inspected by your Toyota dea l e r.
WARNING
■When the hybrid system is hot
Do not remove the engine/power control unit coolant reservoir c aps or the
radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
■ When adding coolant
Coolant is neither plain water nor straight antifreeze. The cor rect 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 p arts or paint.
Radiator and condenser
WARNING
■When the hybrid system is hot
Do not touch the radiator or condenser as they may be hot and c ause seri-
ous injuries, such as burns.

engine oil if necessary. This message may be displayed if the vehicle is
stopped on a slope. Move the vehicle to a level surface and che ck if the mes-
sage disappears.
■ Warning buzzer
P. 503
NOTICE
■If “High Power Consumption Power to Climate Temporarily Limited” is
frequently shown
There is a possible malfunction relating to the charging system or the 12-
volt battery may be deteriorating. Have the vehicle inspected b y your Toyota
dealer.
■ If “Maintenance Required For Traction Battery At Your Dealer” is
shown (AXVH70 model
*)
The hybrid battery (traction battery) is scheduled to be inspected or
replaced. Have the vehicle inspected by your Toyota dealer immediately.
● Continuing to drive the vehicle without having the hybrid batte ry (traction
battery) inspected will cause the hybrid system not to start.
● If the hybrid system does not start, contact your Toyota dealer immedi-
ately.
*: The model code is indicated on the Certification Label. ( P. 545)

5407-2. Steps to take in an emergency
After stopping the hybrid system and waiting for 5 minutes or
more, start the hybrid system again and check for the multi-infor-
mation display.
If the message d oes not disappear:
Stop the hybrid system and contact your Toyota dealer.
If the message is not displayed:
The hybrid system temperature has dropped and the vehicle
may be driven normally.
However, if the message appears again frequently, contact your Toyota
dealer.
WARNING
■ To prevent an accident or injury 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 ho od until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the “READY” indi-
cator is off. When the hybrid system is operating, the gasoline engine may
automatically start, or the cooling fan may suddenly operate even if the
gasoline engine stops. Do not touch or approach rotating parts such as the
fan, which may lead to fingers or clothing (especially a tie, a scarf or a muf-
fler) getting caught, resulting in serious injury.
● Do not loosen the radiator cap and the coolant reservoir cap while the
hybrid system and radiator are hot.
High temperature steam or coolant could spray out.
NOTICE
■When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem 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 sa nd or dust
etc.).
● Do not use any coolant additives.

■Oil capacity (Drain and refill [Reference*])
*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Warm up the engine and turn off the hybrid system, wait
more than 5 minutes, and check the oil level on the dipstick.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat -
isfy the following grade and viscosity.
Oil grade: ILSAC GF-6B multigrade engine oil
Recommended viscosity: SAE 0W-16
SAE 0W-16 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-16 is not available, SAE
0W-20 oil may be used. However,
it must be replaced with SAE 0W-
16 at the next oil change.
Oil viscosity (0W-16 is explained here as an example):
• The 0W in 0W-16 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for ea sier starting of
the engine in cold weather.
• The 16 in 0W-16 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
How to read oil container label:
API registered mark is added to
some oil containers to help you
select the oil you should use.
