■To prevent damage to your vehicle
● Do not turn the heater on and off repeatedly in 5 minute intervals as this
can shorten the life of the heater components. If the engine must be turned
on and off repeatedly within short intervals (such as when the vehicle is
being used for delivery purposes), turn the heater off.
● Do not modify or open the heater without consulting any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional, as
this may cause a heater malfunction or a fire.
● Be careful not to splash or spill liquid directly on the heater or on the
heater fuel pump, as this may cause the heater to malfunction.
● Keep the intake and exhaust pipes of the heater free from water, snow,
ice, mud, etc. If the pipes become clogged, this can cause the heater to
malfunction.
● If you notice anything unusual, such as a fluid leak, smoke and poor oper-
ation, turn off the heater and have your vehicle checked by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.

pipe as they are hot. You may burn
yourself.

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. 434)
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.
