NOTE:
•The torque converter clutch will not engage, and the
transmission will not shift to sixth gear, until the
transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (1.6 to 4.8 km) of driving].
Because sixth gear is disabled, and engine speed is
higher when the torque converter clutch is not en-
gaged, it may seem as if the transmission is not
shifting properly when cold. This is normal. Using the
Electronic Range Select (ERS) feature, when the trans-
mission is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of Overdrive.
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds after starting the engine.
Six-Speed Automatic Transmission – If Equipped
(Chassis Cab Only)
The shift lever position display (located in the instrument
panel cluster) indicates the transmission gear range. The
shift lever is mounted on the right side of the steering
column. You must press the brake pedal to move the shift
lever out of the PARK position (refer to “Brake/
Transmission Shift Interlock System” in this section). To
drive, move the shift lever from PARK or NEUTRAL to
the DRIVE position. Pull the shift lever toward you when
shifting into REVERSE or PARK, or when shifting out of
PARK.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
64 STARTING AND OPERATING
Page 67 of 173

Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
The transmission shift lever has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) shift control (described later). Pressing the ERS
(-/+) switches (on the shift lever) while in the DRIVE
position will select the highest available transmission
gear, and will display that gear in the instrument cluster
as 6, 5, 4, 3, 2, 1.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range.
When parking on a level surface, you may place the shift
lever in the PARK position first, and then apply the
parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.

•Look at the shift lever position display and verify that
it indicates the PARK position.
•With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Set the parking brake and shift the
transmission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can result
in severe transmission damage. Refer to “Recre-
ational Towing” in “Starting And Operating” and
“Towing A Disabled Vehicle” in “What To Do In
Emergencies” for further information.

2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/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 recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the ERS (-)
switch will activate ERS mode, display the current gear in
the instrument cluster, and maintain that gear as the top
available gear. Once in ERS mode, tapping the ERS (-) or
(+) switch will change the top available gear.

To exit ERS mode, simply press and hold the ERS (+)
switch until “D” is once again displayed in the shift lever
position indicator in the instrument cluster.
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 an accident
or personal injury.

NOTE: To select the proper gear position for maximum
deceleration (engine braking), simply press and hold the
ERS (-) switch down. The transmission will shift to the
range from which the vehicle can best be slowed down.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth and sixth gears). The trans-
mission will automatically shift into the Overdrive gear if
the following conditions are present:

Adding Diesel Exhaust Fluid – Chassis Cab Only
The DEF gauge (located on the EVIC display) will
display the level of DEF remaining in the tank. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
•When the DEF gauge reads 75%, add approximately
2 gallons (7.5 Liters) to fill the DEF tank.
•When the DEF gauge reads 50%, add approximately
4 gallons (15 Liters) to fill the DEF tank.
•When the DEF gauge reads 25%, add approximately
6 gallons (23 Liters) to fill the DEF tank.
NOTE: Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF that is used in
your vehicle.
DEF Fill Procedure
NOTE: Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for the correct fluid type.
1. Remove cap from DEF tank (located on drivers side of
the vehicle).

The condition of the air cleaner filter is monitored by the
Engine Control Module. The “SERVICE AIR FILTER”
message will display in the Electronic Vehicle Informa-
tion Center (EVIC) when service is required. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
Do not remove the top of the air filter housing to
inspect the filter element on your diesel engine under
normal operating conditions.
The “SERVICE AIR FILTER” message could be displayed
periodically. This is because engine air flow requirements
change based on driving conditions. As the filter becomes
more restrictive and air flow requirements increase the
“SERVICE AIR FILTER” message will be displayed. The
message may not be displayed in subsequent drive cycles
if the same conditions are not met. The air filter element
should be replaced within 250 miles (402 km) from thefirst time this message is displayed to ensure proper
engine operation during all driving conditions.
CAUTION!
Driving with a restricted air filter can cause engine
damage. Driving in dusty environments for extended
periods will lead to rapid air filter plugging. Action
should be taken as soon as the “SERVICE AIR
FILTER” message is displayed.
If the vehicle experiences a sudden loss of engine power
while being driven in heavy snow or rain, or when
plowing snow, and/or the “SERVICE AIR FILTER” mes-
sage is displayed on the EVIC along with a chime that
repeats every 60 seconds, visually inspect the air filter for
snow/ice build up or extreme water saturation. If the air
filter is not damaged, remove all snow/ice and reinstall
air filter. If the air filter is damaged, replace filter element.

Refer to the following messages that may be displayed on
your Electronic Vehicle Information Center (EVIC):
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.
Perform Service
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is
due, the Electronic Vehicle Information Center (EVIC)
will display “Perform Service”. When the “Perform Ser-
vice” message is displayed on the EVIC it is necessary to
have the emissions maintenance performed. Emissionsmaintenance may include replacing the Closed Crank-
case Ventilation (CCV) filter element, and cleaning of the
EGR Cooler. The procedure for clearing and resetting the
Perform Service
indicator message is located in the
appropriate Service Information.
Exhaust System – Regeneration Required Now
“Exhaust System — Regeneration Required Now” will be
displayed on the Electronic Vehicle Information Center
(EVIC) if the exhaust particulate filter reaches 80% of its
maximum storage capacity. Under conditions of exclu-
sive short duration and low speed driving cycles, your
Cummins diesel engine and exhaust after-treatment
system may never reach the conditions required to re-
move the trapped PM. If this occurs, the “Exhaust System
— Regeneration Required Now” message will be dis-
played in the EVIC. If this message is displayed, you will
hear one chime to assist in alerting you of this condition.
