40 UNDERSTANDING YOUR INSTRUMENT PANEL
the exhaust particulate filter reaches 80% of its maxi-
mum storage capacity. Under conditions of exclusive
short duration and low speed driving cycles, your
diesel engine and exhaust after-treatment system may
never reach the conditions required to cleanse the filter
to remove the trapped PM. If this occurs, the "Exhaust
Filter XX% Full Safely Drive at Highway Speeds to
Remedy" message will be displayed in the EVIC. If
this message is displayed, you will hear one chime to
assist in alerting you of this condition. By simply
driving your vehicle at highway speeds for up to
20 minutes, you can remedy the condition in the
particulate filter system and allow your diesel engine
and exhaust after-treatment system to cleanse the filter
to remove the trapped PM and restore the system to
normal operating condition.
