2011 Ram 3500 manual transmission

A MESSAGE FROM CHRYSLER GROUP LLC
Chrysler Group LLC and Cumminswelcome you as a
Cummins turbocharged diesel-powered truck owner.
Your diesel truck will sound, feel, drive, and operate
differently from a gasoline-powered truck. It is important
that you read and understand this manual.
Almost 100% of the heavy duty trucks in the United
States and Canada are diesel-powered because of the fuel
economy, rugged durability, and high torque which per-
mits pulling heavy loads. Cummins engines power well
over half of these trucks. Now this same technology and
proven performance is yours in your truck equipped
with the Cummins turbocharged diesel engine.
You may find that some of the starting, operating, and
maintenance procedures are different. However, they are
simple to follow and careful adherence to them will
ensure that you take full advantage of the features of this
engine. NOTE:
Some aftermarket products may cause severe
engine/transmission and/or exhaust system damage.
Your vehicle’s Powertrain Control Systems can detect
and store information about vehicle modifications that
increase horsepower and torque output such as whether
or not performance-enhancing powertrain components,
commonly referred to as downloaders, power boxes, or
performance chips have been used.
This information cannot be erased and will stay in the
system’s memory even if the modification is removed.
This information can be retrieved by Chrysler Group
LLC, and service and repair facilities, when servicing
your vehicle. This information may be used to determine
if repair will be covered by warranty.
There is a probability that the use of a “performance
chip” will prohibit the engine from starting. In this
instance, the vehicle will need to be serviced by a
authorized dealer in order to return the vehicle to it’s
factory settings.
4 INTRODUCTION

STEERING WHEEL LOCK — IF EQUIPPED
Your vehicle may be equipped with a passive steering
wheel lock. This lock prevents steering the vehicle with-
out the key fob. If the steering wheel is moved approxi-
mately a half turn in either direction and the key fob is
not in the ignition switch, the steering wheel will lock.
To Manually Lock the Steering Wheel
With the engine running, turn the steering wheel upside
down, turn off the engine and remove the key fob. Turn
the steering wheel slightly in either direction until the
lock engages.
To Release the Steering Wheel Lock
Insert the key fob into the ignition switch and start the
engine. If the key fob is difficult to turn, move the wheel
slightly to the right or left to disengage the lock.
NOTE:If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
ENGINE BREAK-IN RECOMMENDATIONS
The Cummins
turbocharged diesel engine does not
require a break-in period due to its construction. Normal
operation is allowed, providing the following recommen-
dations are followed:
•Warm up the engine before placing it under load.
•Do not operate the engine at idle for prolonged
periods.
•Use the appropriate transmission gear to prevent
engine lugging.
•Observe vehicle oil pressure and temperature indica-
tors.
•Check the coolant and oil levels frequently.
6 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

normal, turn the engine off immediately and call for
service. Refer to “What To Do In Emergencies/If Your
Engine Overheats” in the Owner’s Manual for more
information.
•SERV 4WD Warning LightThis light monitors the electric shift 4WD sys-
tem. If the SERV 4WD warning light stays on or
comes on during driving, it means that the
4WD system is not functioning properly and
that service is required.
•Transmission Temperature Warning Light This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as four-wheel drive
operation (e.g., snow plowing, off-road operation). If this light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the “Transmission Tem-
perature Warning Light” illuminated will eventually
cause severe transmission damage or transmission
failure.
WARNING!
In some circumstances, the “Transmission Tempera-
ture Warning Light” under continued operation,
could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a
fire.

42 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
The starter should not be operated for more than 15-
second intervals. Waiting a few minutes between such
intervals will protect the starter from overheating.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Manual Transmission – If Equipped
Apply the parking brake, place the shift lever in NEU-
TRAL and press the clutch pedal to the floor before
starting the vehicle. This vehicle is equipped with a
clutch interlocking ignition system. It will not start unless
the clutch is fully pressed.
Automatic Transmission – If Equipped
Start the engine with the shift lever in NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Tip Start Feature
Do notpress the accelerator. Turn the ignition switch
briefly to the START position and release it. The starter
motor will continue to run but will automatically disen-
gage when the engine is running.
Extreme Cold Weather
The Cummins diesel engine is equipped with several
features designed to assist cold weather starting and
operation:
•The engine block heater is a resistance heater installed
in the water jacket of the engine just above and behind
the oil filter. It requires a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
44 STARTING AND OPERATING

NOTE:The engine block heater cord is a factory in-
stalled option. If your vehicle is not equipped, heater
cords are available from your authorized MOPAR
dealer.
•A 12 Volt heater built into the fuel filter housing aids in
preventing fuel gelling. It is controlled by a built-in
thermostat.
•A heated intake air system both improves engine
starting and reduces the amount of white smoke
generated by a warming engine.
Normal Starting Procedure – Engine Manifold Air
Temperature Above 66°F (19°C)
Observe the instrument panel cluster lights when starting
the engine.
1. Always apply the parking brake. 2. Shift into PARK for an automatic transmission. For
vehicles equipped with a manual transmission, fully
press and hold the clutch pedal and shift into NEUTRAL.
3. Turn the ignition switch to the ON position and watch
the instrument panel cluster lights.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START the engine before you drain the water
from the fuel filter to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
4. Turn the ignition switch to the START position and
crank the engine. Do not press the accelerator during
starting.

STARTING AND OPERATING 45

NOTE:
•During engine shut down on vehicles equipped with
manual transmissions, it is normal for the diesel
engine to resonate heavily for a moment during engine
shut off. When the engine is connected to a manual
transmission, this resonance causes load gear rattle
from the transmission. This is commonly referred to as
“shut down rattle.” The manufacturer recommends
performing engine shut down with the clutch pedal
pushed to the floor (clutch disengaged). When engine
shut down is performed in this manner the rattle is
reduced (not eliminated).
•Refer to the following chart for proper engine
shutdown.
