NOTICE
■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 duly qualified and equipped professional.
This may cause a heater malfunction or a fire.
● Be careful not to splash water or spill liquid directly on the heater or on the
heater fuel pump. 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 or poor opera-
tion, turn off the heater and have your vehicle checked by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
●Do not touch the heater or its exhaust
pipe as they are hot.
● Keep flammable items such as fuel
away from the heater and its exhaust
pipe. This may cause a fire.
