You may drain the fuel filter yourself. However, as the operation is difficult, we
recommend having it drained by your Lexus dealer. Even if you decide to drain it
yourself, contact your Lexus dealer.
The water in the fuel filter needs to be drained if the fuel system warning message
is shown on the multi-information display and a buzzer (if equipped) sounds.
Turn the engine switch off.
Place a small tray under the drain plug to catch the water and any fuel that
comes out.
Turn the drain plug counterclock-
wise 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.
