When steering wheel operations are heavier than usual, grip the steering
wheel firmly and operate it using more force than usual.
■ If “Hybrid System Overheated. Reduced Output Power.” is shown
This message may be shown when driving under severe operating c ondi-
tions. (For example, when driving up a long steep hill.)
Handling method: P. 755
■ If “Depress Brake When Vehicle is Stopped. Hybrid System may Over-
heat.” is shown

has become extremely low because the shift lever has been left in N for a cer-
tain amount of time.
When operating the vehicle, shift to P and restart the hybrid s ystem.
■ If “Traction battery needs to be protected. Refrain from the use of
position.” is shown
This message may be displayed when the shift lever is in N.
As the hybrid battery (traction battery) cannot be charged when the shift lever
is in N, shift the shift lever to P when the vehicle is stopped .
■ If “Shift is in Release Accelerator Before Shifting” is shown

The coolant level is satisfactory if it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL” line
“LOW” line
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the hybrid system and turn the air conditioning system on to
check that the radiator cooling fans operate and to check for
coolant leaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating b y checking
the fan sound and air flow. If it is difficult to check these, turn the air con-
ditioning system on and off repeatedly. (The fans may not opera te in
freezing temperatures.)
If the fans are not operating:
Stop the hybrid system immediately and contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
If the fans are operating:
Have the vehicle inspected at the nearest any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repaire r.

When trouble arises
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 hood until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the indicator on the
power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may au tomati-
cally start, or the cooling fans may suddenly operate even if t he gasoline
engine stops. Do not touch or approach rotating parts such as t he fan,
which may lead to fingers or clothing (especially a tie, a scar f or a muffler)
getting caught, resulting in serious 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 suff iciently.
Adding cool coolant to a hot hybrid system too quickly can caus e 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 any coolant additive.
