2018 Ram 2500 Owner's Manual

After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.
LIMITED-SLIP DIFFERENTIAL
The limited-slip differential provides additional traction on
snow, ice, mud, sand and gravel, particularly when there is
a difference between the traction characteristics of the
surface under the right and left rear wheels. During normal
6
STARTING AND OPERATING 375

driving and cornering, the limited-slip unit performs simi-
larly to a conventional differential. On slippery surfaces,
however, the differential delivers more of the driving effort
to the rear wheel having the better traction.
The limited-slip differential is especially helpful during
slippery driving conditions. With both rear wheels on a
slippery surface, a slight application of the accelerator will
supply maximum traction. When starting with only one
rear wheel on an excessively slippery surface, slight mo-
mentary application of the parking brake may be necessary
to gain maximum traction.
WARNING!
On vehicles equipped with a limited-slip differential
never run the engine with one rear wheel off the
ground since the vehicle may drive through the rear
wheel remaining on the ground. You could lose control
of the vehicle.
Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could cause
both rear wheels to spin, and allow the vehicle to slide
sideways on the crowned surface of a road or in a turn.
WINCH USAGE — POWER WAGON ONLY (IF
EQUIPPED)
Things To Know Before Using Your Winch
General Winch Information
Your vehicle is equipped with an electric vehicle recovery
winch. This winch uses the electrical power from the
vehicle charging system to power a motor that winds wire
rope into the winch drum via planetary gear reduction. By
nature, a winch is capable of generating very high forces
and should be used with care. Do not operate the winch
without reading and understanding the complete winch
owner’s manual.
Tensioning The Wire Rope
The winch rope must be properly tensioned before use.
Follow the instructions below to tension the rope:
1. Un-spool the wire rope leaving five wraps of rope on the winch drum.
2. Attach the hook to a suitable anchor point.
376 STARTING AND OPERATING

CAUTION!
Be certain the anchor will withstand the load required
to tension the wire rope.
3. Apply at least 500 lbs (227 kg) of tension to the rope while winding the rope. Always use care to ensure the
rope does not pile up on one side of the drum and is
neatly wound onto the drum.
CAUTION!
Wire rope must spool on the winch drum in the
direction indicated on the drum rotation decal on the
winch.
Low Voltage Interrupt
Your winch is equipped with a device that will interrupt
winch function if the vehicle charging system voltage
drops to a low level. The winch will not power-in or out for
30 seconds if this device is tripped. If the interrupt is
tripped, the vehicle should be operated at high idle for a
few minutes to allow the vehicle charging system to
recover before continuing to winch.
Winch Motor Thermal Protection
Your winch is equipped with a thermal protection device in
the motor. If the winch is operated for an excessive
duration, the device may interrupt motor function to
protect the winch motor. During this time the winch will
power-out but will not power-in. Allow the winch motor to
cool for a few minutes before continuing to winch. The
winch will resume normal function once the motor cools.

Understanding The Features Of Your Winch
Winch Components
378 STARTING AND OPERATING

1.Motor: The winch motor is powered by the vehicle
charging system and features a thermal protection
switch that automatically stops motor function in the
power-in direction if the motor gets too hot.
2. Remote Socket: The remote socket allows the remote
control to be attached to the control pack to allow the
winch to function.
3. Winch Drum With Integral Brake: The winch drum
allows the wire rope to be stored on the winch and
transmits force to the wire rope. The winch is equipped
with an integral brake that will stop rotation of the
winch drum if the winch motor is stopped.
4. 3-Stage Planetary Gear Set: Provides balance between
speed and pulling power.
5. Wire Rope: The wire rope allows the winch to be
connected to an anchor to provide a pulling force.
6. Clutch Lever: The clutch lever allows the winch drum to
be disconnected from the winch motor to allow the wire
rope to be pulled from the winch by hand. 7.
Remote Control: The remote control provides the inter-
face between the winch operator and the winch. The
remote control provides the ability to power the winch
in, out, and stop the winch. To operate the winch, the
toggle switch is pressed down to power the winch in
and up to power the winch out. The winch will stop if
the switch is left in the neutral (center) position.
CAUTION!
If not installed, the hook strap must be placed on the
hook.
Fairlead: The fairlead acts as a guide for the wire rope and
minimizes damage to the rope.6

Winch Accessories
The following accessories are necessary to attach the winch
to anchors, change direction of pull, and for safe winching.Gloves:Wire rope, through use, will
develop barbswhich can slice skin. It
is extremely important to wear protec-
tive gloves while operating the winch or
handling the wire rope. Avoid loose
fitting clothes or anything that could
become entangled in the wire rope and
other moving parts.
Snatch/Block Pulley: Used properly, the
multi-purpose snatch block allows you
to (1) increase the winch’s pulling
power; and (2) change your pulling di-
rection without damaging the wire rope.
Proper use of the snatch block is covered
in Before You Pull. Clevis/D-Shackles:
The D-Shackle is a
safe means of connecting the looped
ends of cables, straps and snatch blocks.
The shackle’s pin is threaded to allow
easy removal.
Tree Trunk Protector: Typically made of
tough, high-quality nylon, it provides
the operator an attachment point for the
winch rope to a wide variety of anchor
points and objects, as well as protect
living trees.
