You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer. Even if
you decide to drain it yourself, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
The water in the fuel filter needs to be drained if one of the following
symptoms occurs:
Vehicles without multi-information display
When the fuel system warning light flashes and a buzzer sounds.
( P. 612)
Vehicles with multi-information display
When “WATER ACCUMULATION IN FUEL FILTER SEE
OWNER’S MANUAL”/“Water accumulation in fuel filter See owner’s
manual” is shown on the multi-information display and a buzzer
sounds*1.
Vehicles without smart entry & start system: Turn the engine switch
to the “LOCK” position.
Vehicles with smart entry & start system: Turn the engine switch off.
Place a small tray under the drain plug or drain hose to catch the
water and any fuel that comes out.
Perform the draining as shown in the illustration.
Turn the drain plug counter-
clockwise about 2 to 2 1/2
turns.
Loosening more than this will
cause water oozing from around
the drain plug.
Operate the priming pump
until fuel begins to run out.
After draining, tighten the drain plug by hand.
