1 Stop the vehicle in a safe place
and turn off the air conditioning
system, and then stop the hybrid
system.
2 If you see steam: Carefully lift

7-2. Steps to take in an emergency
When trouble arises
3After 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 any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
4 The coolant level is satisfactory
if it is between the “F” and “L”
lines on the reservoir.
Reservoir
“F” line
“L” line
5 Add coolant if necessary.
Water can be used in an emergency if
coolant is unavailable.
6 Start the hybrid system and turn
the air conditioning system on to
check that the radiator cooling
fan operates and to check for
coolant leaks from the radiator
or hoses.
The fan operates when the air condi- tioning system is turned on immediately
after a cold start. Confirm that the fan is operating by checking the fan sound and air flow. If it is difficult to check
these, turn the air conditioning system on and off repeatedly. (The fan may not operate in freezing temperatures.)
7 If the fan is not operating: Stop
the hybrid system immediately
and contact any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer.
If the fan is operating: Have the
vehicle inspected at the nearest
any authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
If “Hybrid System Overheated
Output Power Reduced” is
shown on the multi-information
display
1 Stop the vehicle in a safe place.

If water was added in an emergency, have the vehicle inspected at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer as soon as possible.
6 After stopping the hybrid system
and waiting for 5 minutes or
more, start the hybrid system
again and check for the multi-
information display.
If the message does not disap-
pear: Stop the hybrid system
and contact any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer.
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 any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

7-2. Steps to take in an emergency
When trouble arises
1Stop the hybrid system. Set the
parking brake and shift the shift
lever to P.
2 Remove the mud, snow or sand
from around the front wheels.
3 Place wood, stones or some
other material under the front
wheels to help provide traction.
4 Restart the hybrid system.
5 Shift the shift lever to D or R and
release the parking brake. Then,
while exercising caution,
depress the accelerator pedal.
■When it is difficult to free the vehi-
cle
Press the switch to turn off TRC.
A message will be shown on the multi-
information display.
WARNING
●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 “READY”
indicator is off. When the hybrid system is operating, the gasoline engine may automatically start, or
the cooling fan may suddenly oper- ate even if the gasoline engine stops. Do not touch or approach
rotating parts such as the fan, which may lead to fingers or cloth-ing (especially a tie, a scarf or a
muffler) getting caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the hybrid system and radiator are hot.
High temperature steam or coolant could spray out.
NOTICE
■When adding engine/power con-trol unit coolant
Add coolant slowly after the hybrid
system has cooled down sufficiently. Adding cool coolant to a hot hybrid system too quickly can cause dam-
age 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.
If the vehicle becomes
stuck
Carry out the following proce-
dures if the tires spin or the
vehicle becomes stuck in mud,
dirt or snow:
