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. Even 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 fuel filter warning
light comes on. (P. 442)
Turn the engine switch to the “LOCK” position (vehicles without a
smart entry & start system) or off (vehicles with a smart entry &
start system).
Place a small tray under the drain plug to catch the water and any
fuel that comes out.
Turn the drain plug counter-
clockwise about 2 to 2 1/2
turns.
Operate the priming pump until
fuel begins to run out.
After draining, tighten the drain plug by hand.
