Diesel Messages And Warnings —
6.7L Cummins Diesel Engine
Diesel Particulate Filter (DPF) Messages
The Cummins diesel engine meets all diesel
emissions standards, resulting in one of the
lowest emitting diesel engines ever pro-
duced. To achieve these emissions stan-
dards, your vehicle is equipped with a state-
of-the-art engine and exhaust system. These
systems are seamlessly integrated into your vehicle and managed by the Powertrain Con-
trol 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 ve-
hicle or engine. The following messages may
display in your instrument cluster display:
• Perform Service — Your vehicle will require
emissions maintenance at a set interval. To
help remind you when this maintenance is
due, the instrument cluster display will
display “Perform Service”. When the “Per-
form Service” message is displayed in the
instrument cluster display it is necessary to have the emissions maintenance per-
formed. Emissions maintenance may in-
clude replacing the Closed Crankcase Ven-
tilation (CCV) filter element. The procedure
for clearing and resetting the "Perform Ser-
vice" indicator message is located in the
appropriate Service Information.
• Exhaust System — Regeneration Required
Now — "Exhaust Filter XX% Full Safely
Drive at Highway Speeds to Remedy" will be
displayed in the instrument cluster display
if the exhaust particulate filter reaches
80% of its maximum storage capacity. Un-
der conditions of exclusive short duration
and low speed driving cycles, your Cum-
mins 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 Rem-
edy” message will be displayed in the in-
strument cluster display. 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 as little as 45 minutes, you can
remedy the condition in the particulate filter

Under some circumstances this mileage
counter may start with a value of less than
150 miles (241 km). For example, if recur-
ring faults are detected in a time interval of
less than 40 hours, the counter may restart
at the value where it stopped when a previ-
ous fault was temporarily remedied, or at a
minimum of 50 miles (80 km).
•

ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects
a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime
will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system isdesigned to be maintenance free, if any of
the following occurs, have an authorized
dealer service the air bag system immedi-
ately.
• The Air Bag Warning Light does not come
on during the four to eight seconds when
the ignition switch is first in the ON/RUN
position.
• The Air Bag Warning Light remains on after the four to eight-second interval.
• The Air Bag Warning Light comes on inter- mittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant Restraint Controller (ORC) may also
be disabled. In this condition the air bags
may not be ready to inflate for your protec-
tion. Have an authorized dealer service the
air bag system immediately.WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first
turned on, stays on after you start the
vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag
system immediately.
Front Air Bags

SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel
usage will influence when the “Oil Change
Required” message is displayed. Severe Op-
erating Conditions can cause the change oil
message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If a scheduled oil
change is performed by someone other than
your authorized dealer, the message can bereset by referring to the steps described under
“Warning And Indicator Lights” or “Instru-
ment Cluster Display” in “Getting To Know
Your Instrument Panel” in your Owner’s
