Ram 3500 2016 Diesel Supplement

managed by the Powertrain Control Module (PCM). The
PCM manages engine combustion to allow the exhaust
system’s catalyst to trap and burn Particulate Matter
(PM) pollutants, with no input or interaction on your
part.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
Your vehicle has the ability to alert you to additional
maintenance required on your vehicle or engine. Refer to
the following messages that may be displayed on your
DID: •
Perform Service — Your vehicle will require emissions
maintenance at a set interval. To help remind you
when this maintenance is due, the Cluster will display
“Perform Service”. When the “Perform Service” mes-
sage is displayed on the DID it is necessary to have the
emissions maintenance performed. Emissions mainte-
nance may include replacing the Closed Crankcase
Ventilation (CCV) filter element. The procedure for
clearing and resetting the Perform Serviceindicator
message is located in the appropriate Service Informa-
tion.
• Exhaust System — Regeneration Required Now —
Exhaust Filter XX% Full Safely Drive at Highway
Speeds to Remedy will be displayed in the Cluster if
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 remove the
