■If “Exhaust Filter Full See Owner’s Manual” is shown on the multi-
information display
●The message may be displayed while
high load driving with particulate mat- ter accumulating.
●Engine 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 engine is regularly started in an extremely cold environ-
ment. Excessive accumulation of par- ticulate matter can be prevented by periodically driving long distances
continuously with intermittent releas- ing of the accelerator pedal, such as when driving on highways and free-
ways.
■If the malfunction indicator lamp comes on or “Engine Maintenance Required Visit Your Dealer” is
shown on the multi-information display
The amount of accumulated particulate
matter has exceeded a certain level. Have the vehicle inspected by any
GPF (Gasoline Particu-
late Filter) system*
The GPF system collects par-
ticulate matter in the exhaust
gas by using an exhaust gas
filter.
The system will operate to
regenerate the filter automati-
cally, depending on the vehicle
conditions.
