14. Begin winching. With the winching vehicles
engine on and light tension already on the
synthetic rope, begin winching slowly and
steadily. Be sure that the rope is winding
evenly and tightly around the spooling
drum. For additional assistance, the
winched vehicle can be slowly driven while
being pulled by the winch. Continue pulling
until the vehicle is on stable ground. If you
are able to drive the vehicle, the winching
operation is complete.

Using The Remote Control

NOTE:
Avoid overheating the winch motor. For extended winching, stop at reasonable
intervals to allow the winch motor to cool
down.
What to look for under load: The synthetic rope must always spool onto the drum as
indicated by the drum rotation decal on
the winch. As you power-in, make sure
the synthetic rope winds evenly and
tightly on the drum. This prevents the
outer rope wraps from drawing into the
inner wraps, binding and damaging the
synthetic rope. Avoid shock loads by
using the control switch intermittently to
take up rope slack. Shock loads can
momentarily far exceed the winch and
synthetic rope ratings. During side pulls
the synthetic rope tends to stack up at
one end of the drum. This stack can
become large enough to cause serious
damage to the winch. So, line up pulls as
straight ahead as possible and stop
winching if the synthetic rope comes
close to the tie rods or mounting plate. To
fix an uneven stack, spool out that
section of the rope and reposition it to
the opposite end of the drum, which will
free up space for continued winching.
15. Secure vehicle. Once recovery of the vehicle is complete, be sure to secure the vehicle's
brakes and shift the transmission to PARK.
Release tension in the synthetic rope. 16. Disconnect the synthetic rope, and discon
-
nect from the anchor.
17. Rewind the synthetic rope. The person handling the synthetic rope should walk the
rope in and not let it slide through the hand,
control the winch at all times.

Rewinding The Synthetic Rope

WARNING!
To prevent serious injury, NEVER put your
fingers inside the hook area as you are
powering-in.

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.
