2017 Ram 5500 Chassis Cab low oil pressure

Follow the steps in the “Normal Starting” procedure
except:
1. The “Wait To Start” telltale will remain on for a period oftime that varies depending on the engine temperature.
2. While the Wait To Start” telltale is on, the instrument
cluster will additionally display a gauge or bar whose
initial length represents the full Wait To Starttime
period. Its length will decrease until it disappears when
the Wait To Start time has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for further
information.
3. After the “Wait To Start” telltale goes off, turn the ignition switch to the START position. Do not press the
accelerator during starting.
CAUTION!
Do not crank engine for more than 15 seconds at a time
or starter motor damage may result. Turn the ignition
switch to the OFF position and wait at least two
minutes for the starter to cool before repeating start
procedure.
4. After engine start-up, check that the oil pressure warn- ing light has turned off.
5. Allow the engine to idle about three minutes until the manifold heaters have completed the post-heat cycle.
6. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically increase to
1,000 RPM and engage the Variable Geometry Turbo-
charger at low coolant temperatures to improve engine
warm-up.
• Automatic equipped vehicles with optional Keyless
Enter-N-Go – If the start button is pushed once while in
park with the ignition off and driver ’s foot on the brake
pedal, the vehicle will automatically crank and start
after the Wait to Start time has elapsed. If it is desired to

WARNING!(Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous 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 gear
selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
NORMAL OPERATION — DIESEL ENGINE
Observe the following when the engine is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Engine oil pressure is above 10 psi (69 kPa) at idle.
• Voltmeter operation:
The voltmeter may show a gauge fluctuation at various
engine temperatures. This cycling operation is caused by
the post-heat cycle of the intake manifold heater system.
The number of cycles and the length of the cycling opera-
tion is controlled by the engine control module. Post-heat
operation can run for several minutes, and then the elec-
trical system and voltmeter needle will stabilize.
The cycling action will cause temporary dimming of the
headlamps, interior lamps, and also a noticeable reduction
in blower motor speed.
130 STARTING AND OPERATING

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 perfor-
mance. No-load engine speeds should be kept under 1,200
RPM during the warm-up period, especially in cold ambi-
ent 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 0 mph (0 km/h).
• Applying the throttle will cancel fast idle.
• Operating the exhaust brake at idle will greatly improve
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 tem-
peratures 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 or the truck is driven on low
engine speed drive cycles for more than 2 hours, the
system will automatically 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 also5

Programmable Maximum Vehicle Speed (Chassis
Cab Only)
This feature allows the owner to set a maximum vehicle
speed for the vehicle. The 3500 Series maximum vehicle
speed can be set between 40 mph (64 km/h) and 87 mph
(140 km/h). The 4500/5500 Series maximum vehicle speed
can be set between 40 mph (64 km/h) and 85 mph
(136 km/h). See your local authorized dealer to enable this
feature.
NOTE:DO NOT set the maximum vehicle speed to a value
greater than what the vehicle tires are rated for.
Operating Precautions
Avoid Overheating The Engine
The temperature of the engine coolant (antifreeze) (a
mixture of 50% ethylene-glycol and 50% water) must not
exceed the normal range of the temperature gauge 240°F
(116°C) with a 21 psi (145 kPa) coolant pressure cap.
Usually the engine coolant (antifreeze) temperature indi-
cated during operation will be to the left of center in the
normal range of the gauge.
Avoid Low Coolant Temperature Operation
Continual operation at low engine coolant (antifreeze)
temperature below the normal range on the gauge 140°F
(60°C) can be harmful to the engine. Low engine coolant
(antifreeze) temperature can cause incomplete combustion
which allows carbon and varnish to form on piston rings
and injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the lubricating oil and causing rapid
wear to the engine.
Cooling System Tips — Automatic Transmission
To reduce potential for engine and transmission overheat-
ing in high ambient temperature conditions, take the
following actions:
• City Driving —
When stopped, shift the transmission into NEUTRAL and
increase engine idle speed.
• Highway Driving —
Reduce your speed.
• Up Steep Hills —
Select a lower transmission gear.
• Air Conditioning —
Turn it off temporarily.
136 STARTING AND OPERATING

Do Not Operate The Engine With Low Oil Pressure
When the engine is at normal operating temperature, the
minimum oil pressures required are:
Idle 700 to 800 RPM 10 psi (69 kPa)
Full speed and load 30 psi (207 kPa)
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.
Do Not Operate The Engine With Failed Parts
All engine failures give some warning before the parts fail.
Be on the alert for changes in performance, sounds, and
visual evidence that the engine requires service. Some
important clues are:
•Engine misfiring or vibrating severely.
• Sudden loss of power.
• Unusual engine noises. •
Fuel, oil or coolant leaks.
• Sudden change, outside the normal operating range, in
the engine operating temperature.
• Excessive smoke.
• Oil pressure drop.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and permits
quicker starts in cold weather. Connect the heater cord to a
ground-fault interrupter protected 110–115 Volt AC electri-
cal outlet with a grounded, three-wire extension cord.
The engine block heater cord is routed under the hood to
the right side and can be located just behind the grille near
the headlamp.
NOTE: The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized MOPAR dealer.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.5
STARTING AND OPERATING 137

Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil only
when the level on the dipstick is below the “ADD” mark.
The total capacity from the ADD mark to the Full mark is
2 qts (1.9L).
CAUTION!
Overfilling or underfilling the crankcase will cause oil
aeration or loss of oil pressure. This could damage your
engine.
Never operate the engine with oil level below the “ADD”
mark or above the upper “SAFE” mark.
Change Engine Oil
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only rec-
ommends engine oils that are API CJ-4 certified and meet
the requirements of FCA LLC. Use MOPAR or an equiva-
lent oil meeting FCA Material Standard MS-10902. Prod-
ucts meeting Cummins CES 20081 may also be used. The
identification of these engine oils are typically located on
the back of the oil container.
