STARTING AND OPERATING333
Shifting Into (N) NEUTRAL
Use the following procedure to prepare your
vehicle for recreational towing.

1. Bring the vehicle to a complete stop on
level ground, with the engine running.
Firmly apply the parking brake.

2. Shift the transmission to NEUTRAL. NOTE:
If vehicle is equipped with air suspension,
ensure the vehicle is set to Normal Ride Height.
3. Press and hold the brake pedal.
4. Shift the transfer case into N (Neutral):
With manual shift transfer case, shift the
transfer case lever into N (Neutral)
With electronic shift transfer case, push and hold the transfer case N (Neutral)
button. Some models have a small,
recessed “N” button (at the center of the
transfer case switches) that must be
pushed using a ballpoint pen or similar
object. Other models have a rectangular
N (Neutral) switch, below the rotary
transfer case control knob. The N
(Neutral) indicator light will blink while
the shift is in progress. The light will stop
blinking (stay on solid) when the shift to N
(Neutral) is complete. After the shift is
completed and the N (Neutral) light stays
on, release the N (Neutral) button.
5. Release the parking brake.
6. Shift the transmission into REVERSE. 7. Release the brake pedal for five seconds
and ensure that there is no vehicle move-
ment.
8. Repeat steps 6 and 7 with automatic trans -
mission in DRIVE.
9. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn off the engine.
For vehicles with Keyless Enter-N-Go, push
and hold the ENGINE START/STOP button
until the engine shuts off.
10. Shift the transmission into PARK. On 8-speed transmissions the shifter will auto -
matically select PARK when the engine is
turned off.
11. Turn the ignition to the OFF mode, then cycle the ignition to the RUN mode and back
to the OFF mode. Remove the key fob from
the ignition.
12. Attach the vehicle to the tow vehicle using a suitable tow bar.
13. Release the parking brake.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the NEUTRAL (N) position without first
fully engaging the parking brake. The transfer
case NEUTRAL (N) position disengages both
the front and rear driveshafts from the
powertrain, and will allow the vehicle to roll,
even if the automatic transmission is in PARK.
The parking brake should always be applied
when the driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to
prevent damage to internal parts.

370IN CASE OF EMERGENCY
If the key fob is unavailable or the vehicle's
battery is discharged, refer to ”Manual Park
Release” in this section for instructions on
shifting the transmission out of PARK for
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground
using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
towed (with rear wheels ON the ground) under
the following conditions:
The transmission must be in NEUTRAL. NOTE:
Refer to “Manual Park Release” in this section
for instructions on shifting the transmission to
NEUTRAL when the engine is OFF.
The towing speed must not exceed 30 mph
(48 km/h).
The towing distance must not exceed
30 miles (48 km) for 8–speed transmission.
The towing distance must not exceed
15 miles (24 km) for 6–speed transmission.
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km) for 8–speed transmission, tow with the rear wheels
OFF the ground. Acceptable methods are to tow
the vehicle on a flatbed, or with the front wheels
raised and the rear wheels on a towing dolly, or
(when using a suitable steering wheel stabilizer
to hold the front wheels in the straight position)
with the rear wheels raised and the front wheels
on the ground.
Four-Wheel Drive Models
The manufacturer recommends towing with all
wheels OFF the ground. Acceptable methods
are to tow the vehicle on a flatbed or with one
end of vehicle raised and the opposite end on a
towing dolly.
If flatbed equipment is not available, and the
transfer case is operable, the vehicle may be
towed (in the forward direction, with ALL wheels
on the ground), IF the transfer case is in
NEUTRAL (N) and the transmission is in PARK.
Refer to “Recreational Towing” in “Starting And
Operating” for further information and detailed
instructions.
CAUTION!
Do not use sling type equipment when
towing. Vehicle damage may occur.
When securing the vehicle to a flat bed
truck, do not attach to front or rear suspen -
sion components. Damage to your vehicle
may result from improper towing.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission
damage. Damage from improper towing is not
covered under the New Vehicle Limited
Warranty.

408SERVICING AND MAINTENANCE
exhaust after-treatment system work together
to achieve the EPA Heavy Duty Diesel Engine
Emissions Standards. These systems are seam -
lessly integrated into your vehicle and managed
by the Cummins 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.
If the engine is allowed to idle or the truck is
driven on low engine speed drive cycles for
more than two hours, the system will automati -
cally enter an emissions operating mode that
will increase the engine idle speed to 900 RPM
(1050 RPM for Chassis Cab). While in this
mode, which is designed to help maintain the
Diesel Particulate Filter, the engine idle speed
will return to normal when the brake pedal is
applied. A small change in engine tone or a
slight change in engine performance while
accelerating may also be noticeable at speeds
below 20 mph (32 kmh). This operating mode
may last for up to an hour of idle time, or around
20 minutes of driving time.
Additionally, your vehicle has the ability to alert
you to additional maintenance required on your
truck or engine. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) sometimes known
simply by the name of its active component,
UREA—is a key component of selective catalytic
reduction (SCR) systems, which help diesel
vehicles meet stringent emission regulations.
DEF is a liquid reducing agent that reacts with
engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx)
into harmless nitrogen and water vapor.
Refer to “Fluids And Lubricants” in “Technical
Specification” for further information.
You can receive assistance in locating DEF in
the United States by calling 866-RAM-INFO (866-726-4636). In Canada call
1–800–465–2001 (English) or
1–800–387–9983 (French)
You can receive assistance in locating DEF by
contacting an authorized dealer.
Body Lubrication
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, decklid, sliding
doors and hood hinges, should be lubricated
periodically with a lithium based grease, such
as Mopar Spray White Lube to ensure quiet,
easy operation and to protect against rust and
wear. Prior to the application of any lubricant,
the parts concerned should be wiped clean to
remove dust and grit; after lubricating, excess
oil and grease should be removed. Particular
attention should also be given to hood latching
components to ensure proper function. When
performing other underhood services, the hood
latch, release mechanism and safety catch
should be cleaned and lubricated.
The external lock cylinders should be lubricated
twice a year, preferably in the Autumn and
Spring. Apply a small amount of a high quality
lubricant, such as Mopar Lock Cylinder Lubri
-
cant directly into the lock cylinder.
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.
