2009 DODGE RAM 3500 DIESEL Owners Manual

•
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•
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, or 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 brake drums and rotors,
brake linings, and axle yokes inspected and cleaned as
soon as possible.
•
If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
packed material. Packed foreign material can cause a
wheel imbalance and cleaning the wheels will correct
the situation.
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 an accident. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary. Failure to do so may result
is serious injury.

LIMITED-SLIP DIFFERENTIAL – IF EQUIPPEDThe 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 driving and cornering, the limited-slip unit per-
forms similarly to a conventional differential. On slip-
pery 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
momentary 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.DRIVING ON SLIPPERY SURFACESWhen driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping

ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if the road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front of you to avoid a collision in a sudden
stop.DRIVING THROUGH WATERDriving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.Shallow Standing WaterAlthough your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
STARTING AND OPERATING 305

CAUTION!
•
Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
•
Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing wa-
ter.
•
Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.(Continued)
CAUTION! (Continued)
•
Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission/transaxle, axle, etc.) for signs of con-
tamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water.
Do not continue to operate the vehicle if any fluid
appears contaminated, as this may result in further
damage. Such damage is not covered by the New
Vehicle Limited Warranty.
•
Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
306 STARTING AND OPERATING

WARNING!
•
Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•
Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•
Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•
Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
DRIVING OFF-ROAD — RAM TRUCK ONLYCare should be taken when attempting to climb steep
hills or driving diagonally across a hill or slope. If natural
obstacles force you to travel diagonally up or down a hill,
choose a mild angle and keep as little side tilt as possible.
Keep the vehicle moving and make turns slowly and
cautiously.
If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL, or
diagonally across the hill.
When driving over sand, mud, and other soft terrain,
shift to low gear and drive steadily. Apply the accelerator
slowly to avoid spinning the wheels.
DO NOT REDUCE the tire pressures for this type of
driving.
STARTING AND OPERATING 307

NOTE:After off-road usage, particularly in sand or
mud, inspect the underside of the vehicle for accumu-
lated dirt at the propeller shaft, axles, U-joints, brake
rotors and calipers.
Use a hose to clean off any accumulation of dirt or mud.
Check the exhaust system and all exposed components
for any sign of damage.
If you experience unusual vibration after driving in mud,
slush or similar conditions, check the wheels for im-
pacted material. Impacted foreign material can cause a
wheel imbalance. Removing the foreign material from
the wheels will correct the situation.
WINCH USAGE – IF EQUIPPED (POWER WAGON
ONLY)
Things To Know Before Using Your Winch
General Winch InformationYour 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 reduc-
tion. 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 com-
plete winch owner’s manual.Tensioning the Wire RopeThe 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.
308 STARTING AND OPERATING

2. Attach the hook to a suitable anchor point.
CAUTION!
Be certain the anchor will withstand the load re-
quired 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 InterruptYour 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 ProtectionYour 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.
