●Hybrid system output (engine speed) is restricted when a certain amount of
particulate matter accumulates, how- ever, it is possible to drive the vehicle unless the malfunction indicator lamp
comes on.
●Particulate matter can accumulate
more quickly if the vehicle is fre- quently driven short trips or at low speeds, or if the hybrid system is reg-
ularly started in an extremely cold environment. Excessive accumula-
tion of particulate matter can be pre- vented by periodically driving long distances continuously with intermit-
tent releasing of the accelerator pedal, such as when driving on highways and freeways.
■If the malfunction indicator lamp
comes on or “Hybrid System Mal- function Output Power Reduced Visit Your Dealer” is shown on the
multi-information display
