service interval reset Ram 3500 2018 Quick Reference Guide

• Also the DEF gauge may also not imme-diately update after a refill if the tem-
perature of the DEF fluid is below 12°F
(-11°C). The DEF line heater will usually
warm up the DEF fluid and allow the
gauge to update after a period of run
time. Under very cold conditions, it is
possible that the gauge may not reflect
the new fill level for several drives.
• Should you run your vehicle out of DEF, a minimum of 2 gallons (7.6 liters) of DEF is
required for the engine to restart.
•
Never “top-off” the DEF tank after a normal
DEF fill. If DEF is spilled, it should be cleaned
with mild soap and water to prevent corrosion or
damage to components and finished surfaces.
• Your RAM is also equipped with a Diesel Particulate Filter (DPF) that removes diesel
particulate matter or soot from the exhaust
gas. Automatic regeneration self-cleaning
cycles occur when the correct operating con-
ditions are met. • The instrument cluster display will indicate
when a regeneration is in progress and will
provide instructions if any action is required.

• Perform Service — Your vehicle will require
emissions maintenance at a set interval.
To help remind you when this maintenance

• Exhaust System — Regeneration Required
Now— Exhaust Filter XX% Full Safely Drive
at Highway Speeds to Remedy will be dis-
played in the Cluster if the exhaust particu-
late filter reaches 80% of its maximum stor-
age capacity. Under conditions of exclusive
short duration and low speed driving cycles,
your diesel engine and exhaust after-
treatment system may never reach the con-
ditions required 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 Instrument
Cluster Display. If this message is displayed,
you will hear one chime to assist in alerting
