■Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even
when vehicle operation and driving conditions are the same.
■Outside temperature display
In the following situations, the correct outside temperature may not be dis-

●When stopped, or driving at low speeds (less than 16 mph [25 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
●When “” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to your Toyota dealer.
■Fuel gauge and driving range display
The fuel gauge and driving range display are linked. If the fuel gauge and
driving range display do not update after refueling a small amount, they can
be updated by performing the following procedure:
Stop the vehicle on a level surface.
Wait until the fuel in the fuel tank stabilizes.
Press the ODO/TRIP switch to change the odometer and trip meter display
to the odometer.
Turn the power switch off.
While pressing and holding the ODO/TRIP switch, turn the power switch to
ON mode.
Continue holding the ODO/TRIP switch for approximately 5 seconds.
Release the switch when the odometer begins blinking.
Updating will be complete when the odometer blinks for approximately 5
seconds and then returns to the normal display.
NOTICE
■To prevent damage to the engine and its components
The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 537)

Engine coolant reservoir
The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the hybrid system is cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L”
line, add coolant up to the “F” line.
(P. 537)
Power control unit coolant reservoir
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the hybrid system is cold.

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 objects.
If either of the above parts is extremely dirty or you are not sure of
their condition, have your vehicle inspected by your Toyota dealer.
WARNING
■When the hybrid system is hot
Do not remove the engine/power control unit coolant reservoir caps 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 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 and condenser
WARNING
■When the hybrid system is hot
Do not touch the radiator or condenser as they may be hot and cause seri-
ous injuries, such as burns.

When trouble arises
■If the needle of the engine coolant temperature gauge enters
the red zone or “Engine Coolant Temp High Stop in a Safe
Place See Owner’s Manual” is shown on the multi-information
display
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has
cooled down sufficiently,
inspect the hoses and radiator
core (radiator) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
If your vehicle overheats
The following may indicate that your vehicle is overheating.
●The needle of the engine coolant temperature gauge (P. 100)
