2012 Ram 5500 Chassis Cab automatic transmission

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.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 328 ft (100 m).
NOTE:
•The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
•The remote start system will wait for the “Wait To Start
Light” to extinguish before cranking the engine. This
allows time for the intake heater to pre-heat the
incoming air, and is normal operation in cold weather.

32 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.
•Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be seriously or fatally injured. Children
should be warned not to touch the parking brake,
brake pedal or the shift lever. Do not leave the key
in the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
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.
34 STARTING AND OPERATING

Extreme Cold Weather
The Cumminsdiesel 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.
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.

*No. 1 Ultra Low Sulfur Diesel Fuel should only be used
where extended arctic conditions (-10°F/-23°C) exist.
NOTE:
•Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
•Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.
•The engine requires the use of“Ultra Low Sulfur
Diesel Fuel”. Use of incorrect fuel could result in
engine and exhaust system damage. Refer to “Fuel
Requirements” in “Starting and Operating” for further
information.
Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for the correct engine oil viscosity.
Winter Front Usage
If a winter front or cold weather cover is to be used, a
percentage of the total grille opening area must be left
uncovered to provide sufficient air flow to the charge air
cooler and automatic transmission oil cooler. The per-
centage of opening must be increased with the increasing
ambient air temperature and/or engine load. If the
cooling fan can be heard cycling frequently, increase the
size of the opening in the winter front. A suitable cold
weather cover is available from your MOPAR dealer.
42 STARTING AND OPERATING

Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°C). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized MOPARdealer.
Engine Warm-Up
Avoid full throttle operation when the engine is cold.
When starting a cold engine, bring the engine up to
operating speed slowly to allow the oil pressure to
stabilize as the engine warms up.
NOTE:High-speed, no-load running of a cold engine
can result in excessive white smoke and poor engine
performance. No-load engine speeds should be kept
under 1,200 RPM during the warm-up period, especially
in cold ambient temperature conditions. Your vehicle is equipped with a turbo speed limiter, this
feature limits the engine speed to 1,200 RPM when
engine coolant temperatures are below 70°F (21°C). This
feature is designed to protect the turbocharger from
damage and will only operate in PARK or NEUTRAL.
If temperatures are below 32°F (0°C), operate the engine
at moderate speeds for five minutes before full loads are
applied.
NOTE:•If ambient temperatures are low and the coolant
temperature is below 180°F (82°C), the engine idle
speed will slowly increase to 1,000 RPM after two
minutes of idle, if the following conditions are met:
•foot is off brake pedal and throttle pedal
•automatic transmission is in PARK
•vehicle speed is zero
•Applying the throttle will cancel fast idle

STARTING AND OPERATING 43

•If the engine is equipped with an exhaust brake,
operating the exhaust brake at idle will greatly im-
prove warm up rate and will help keep the engine
close to operating temperature during extended idle.
Engine Idling
Avoid prolonged idling, long periods of idling may be
harmful to your engine because combustion chamber
temperatures can drop so low that the fuel may not burn
completely. Incomplete combustion allows carbon and
varnish to form on piston rings, engine valves, and
injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the oil and causing rapid wear to the
engine.
If the engine is allowed to idle, under some conditions
the idle speed may increase to 900 RPM then return to
normal idle speed. This is normal operation.NOTE:
For EVIC messages related to the vehicle’s
exhaust system, refer to “Maintenance Procedures/
Intervention Regeneration Strategy – EVIC Message Pro-
cess Flow” in “Maintaining Your Vehicle” for further
information.Idle-Up Feature – Automatic Transmission Only
The driver-controlled high idle speed feature will help
increase cylinder temperatures and provide additional
cab heat, however, excessive idling may still cause the
exhaust aftertreatment system to not properly regenerate.
Extended periods of idle time should be avoided.
The Idle-Up feature uses the speed control switches to
increase engine idle speed and quickly warm the vehi-
cle’s interior.
1. With the transmission in PARK, the parking brake
applied, and the engine running, press the speed control
switch to the ON position, then press the SET switch.
