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.

tion, turn off the heater and have your vehicle checked by any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
