DIESEL MESSAGES AND WARNINGS
Diesel Particulate Filter (DPF) Messages
The Cummins® diesel engine meets all diesel
emissions standards, resulting in one of the lowest
emitting diesel engines ever produced. To achieve
these emissions standards, 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 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.
Your vehicle has the ability to alert you to
additional maintenance required on your vehicle or
engine. The following messages may display in
your instrument cluster display:
Perform Service
— Your vehicle will require emis -
sions maintenance at a set interval. To help
remind you when this maintenance is due, the
instrument cluster display will display “Perform
Service”. When the “Perform Service” message
is displayed in the instrument cluster display it is
necessary to have the emissions maintenance
performed. Emissions maintenance may
include replacing the Closed Crankcase Ventila -
tion (CCV) filter element. The procedure for
clearing and resetting the "Perform Service"
indicator message is located in the appropriate
Service Information.

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.

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. Under conditions of exclusive
short duration and low speed driving cycles,
your Cummins® diesel engine and exhaust
after-treatment system may never reach the
conditions 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 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 system and
allow your Cummins® diesel engine and
exhaust after-treatment system to remove the
trapped PM and restore the system to normal
operating condition.
Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — Indicates that the DPF
is self-cleaning. Maintain your current driving
condition until regeneration is completed.
Exhaust System — Regeneration Completed —
This message indicates that the DPF
self-cleaning is completed. If this message is
displayed, you will hear one chime to assist in
alerting you of this condition.
Exhaust Service Required — See Dealer Now —
This message indicates regeneration has been
disabled due to a system malfunction. At this
point the engine Powertrain Control Module
(PCM) will register a fault code, the instrument
panel will display a MIL light.
Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM has
derated the engine to limit the likelihood of
permanent damage to the after-treatment
system. If this condition is not corrected and a
dealer service is not performed, extensive
exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have
your vehicle serviced by an authorized dealer.
NOTE:Failing to follow the oil change indicator, changing
your oil and resetting the oil change indicator by
0 miles remaining will prevent the diesel exhaust
filter from performing it's cleaning routine. This will
shortly result in a Malfunction Indicator Light (MIL)
and reduced engine power. Only an authorized
dealer will be able to correct this condition.
Cold Ambient Derate Mode Messages
The vehicle will display messages when a derate
(engine power reduction) is activated to protect the
engine during start-up in cold ambient
temperatures.
Engine Power Reduced During Warm-up — This
message will display during start-up when the
ambient temperature is between 10°F (-12°C)
and -10°F (-23°C).
Engine Power Reduced Up To 30 Sec (Seconds)
During Warm-up — This message will display
during start-up when the ambient temperature
is between -10°F (-23°C) and -25°F (-32°C).
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with continued
operation.

134STARTING AND OPERATING
engine shutdown, perform this procedure only in a
desired location (preferably, at an authorized
dealer).

1. Stop the vehicle.

2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the
highest available gear when the transmission is in
DRIVE. For example, if you set the transmission
gear limit to FOURTH gear, the transmission will not shift above FOURTH gear (except to prevent
engine overspeed), but will shift through the lower
gears normally.
You can switch between DRIVE and ERS mode at
any vehicle speed. When the transmission gear
selector is in DRIVE, the transmission will operate
automatically, shifting between all available gears.
Tapping the GEAR “–” switch (on the steering
wheel) will activate ERS mode, display the current
gear in the instrument cluster, and set that gear as
the top available gear. Once in ERS mode, tapping
the GEAR “–” or GEAR “+” switch will change the
top available gear.

ERS Control
To exit ERS mode, simply push and hold the
GEAR “+” switch until the gear limit display
disappears from the instrument cluster.
When to Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying
a heavy load, etc., and frequent transmission
shifting occurs, push the TOW/HAUL switch to
activate TOW/HAUL mode. This will improve
performance and reduce the potential for
transmission overheating or failure due to
excessive shifting.

TOW/HAUL Switch

1 — GEAR “+” Switch
2 — GEAR “–” Switch
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

23_DPF_OM_EN_USC_t.book Page 134

STARTING AND OPERATING137
If the transmission temperature exceeds normal
operating limits, the powertrain controller will
modify the transmission shift schedule and expand
the range of torque converter clutch engagement.
This is done to prevent transmission damage due
to overheating.
If the transmission becomes extremely hot or is in
danger of overheating, the Transmission
Temperature Warning Light may illuminate and the
transmission may operate differently until the
transmission cools down.
NOTE:Use caution when operating a heavily loaded
vehicle at low speeds (such as towing a trailer up a
steep grade, or in stop-and-go traffic) during hot
weather. In these conditions, torque converter slip
can impose a significant additional heat load on
the cooling system. Downshifting the transmission
to the lowest possible gear (when climbing a
grade), or shifting to NEUTRAL (when stopped in
heavy traffic) can help to reduce this excess heat
generation.
During cold temperatures, transmission operation
may be modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm-up time of the
engine and transmission to achieve maximum
efficiency. Engagement of the torque converter
clutch is inhibited until the transmission fluid is
warm Ú page 139. On trucks with AS66RC or AS69RC transmission,
FIFTH and SIXTH gears may be inhibited briefly on
cold starts below 41°F (5°C), and during very cold
temperatures (-4°F [-20°C] or below), operation
may briefly be limited to third gear only. During this
condition, the ability of the vehicle to accelerate
under heavily loaded conditions may be reduced.
In all cases, normal operation will resume once the
transmission temperature has risen to a suitable
level.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission remains in THIRD gear
regardless of which forward gear is selected. If an
AS66RC/AS69RC equipped truck enters
Transmission Limp Home Mode at highway
speeds, it will initially engage FIFTH gear, until the
vehicle slows to a speed where THIRD gear can be
engaged. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Transmission Limp
Home Mode allows the vehicle to be driven to an
authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK.
3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.

148STARTING AND OPERATING
HYDRAULIC POWER STEERING
The standard power steering system provides
increased vehicle response and ease of
maneuverability in tight spaces. The system will
provide mechanical steering capability if power
assist is lost.
If for some reason the power assist is interrupted,
it will still be possible to steer your vehicle. Under
these conditions, you will observe a substantial
increase in steering effort, especially at very low
vehicle speeds and during parking maneuvers.
NOTE:
Increased noise levels at the end of the steering
wheel travel are considered normal and do not
indicate that there is a problem with the power
steering system.
Upon initial start-up in cold weather, the power
steering pump may make noise for a short
amount of time. This is due to the cold, thick
fluid in the steering system. This noise should
be considered normal, and it does not in any
way damage the steering system.
POWER STEERING FLUID CHECK
Checking the power steering fluid level at a defined
service interval is not required. The fluid should
only be checked if a leak is suspected, abnormal
noises are apparent, and/or the system is not
functioning as anticipated. Check fluid level when
the engine is cold and off. Coordinate inspection
efforts through an authorized dealer. If necessary, add fluid to restore to the proper
indicated level. With a clean cloth, wipe any spilled
fluid from all surfaces Ú
page 421.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
CAUTION!
Prolonged operation of the steering system at
the end of the steering wheel travel will increase
the steering fluid temperature and it should be
avoided when possible. Damage to the power
steering pump may occur.
WARNING!
Fluid level should be checked on a level surface
and with the engine off to prevent injury from
moving parts and to ensure accurate fluid level
reading. Do not overfill. Use only manufacturer's
recommended power steering fluid.
CAUTION!
Do not use chemical flushes in your power
steering system as the chemicals can damage
your power steering components. Such damage
is not covered by the New Vehicle Limited
Warranty.
