The coolant level is satisfactory if it is between the “FULL” and “LOW” lines on
the reservoir when the engine is cold.
■Engine coolant reservoir Reservoir cap

If the level is on or below the “LOW”
line, add coolant up to the “FULL”
line. ( P. 5 8 4 )
■Intercooler coolant reservoir

The coolant level is satisfactory if it is between the “FULL” and “LOW” lines on
the reservoir.
Add coolant if necessary.
Start the engine and turn the air conditioning system on to check that the radi-
ator 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 immediately after a
cold start. Confirm that the fans are oper ating 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 fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately an d contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Lexus dealer.
