Fuel filter (diesel engine)
You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional. Event if you decide to drain it yourself, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
The water in the fuel filter needs to be drained if the “DRAIN WATER
FROM FUEL FILTER” warning message is shown on the multi-infor-
mation display and a buzzer sounds. (P. 629)
Turn the “ENGINE START STOP” switch to off (vehicles with
smart entry & start system) or the engine switch to the “LOCK”
position (vehicles without smart entry & start system).
Place a small tray under the drain plug to catch the water and
any fuel that comes out.
