5-2. Steps to take in an emergency
VERSO_EE_OM64517E
Diesel engine
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact any autho-
rized Toyota dealer or repairer, or
another duly qualified and
equipped professional.
The coolant level is satisfactory if
it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL”
“LOW”
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine 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 conditioning 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.)
