2022 RAM 1500 Oil pressure

146STARTING AND OPERATING
NORMAL OPERATION — DIESEL ENGINE
Observe the following when the diesel engine is
operating.
All message center lights are off.
Malfunction Indicator Light (MIL) is off.
Engine Oil Pressure telltale is not illuminated.
Voltmeter operation:
The voltmeter may show a gauge fluctuation at
various engine temperatures. This is caused by the
glow plug heating system. The number of cycles
and the length of the cycling operation is controlled
by the engine control module. Glow plug heater
operation can run for several minutes, once the
heater operation is complete the voltmeter needle
will stabilize.
COLD WEATHER PRECAUTIONS
Operation in ambient temperature below 32°F
(0°C) may require special considerations. The
following charts suggest these options:
Fuel Operating Range
NOTE:Use Ultra Low Sulfur Diesel (ULSD) Fuels ONLY.

Fuel Operating Range Chart

*Number 1 ULSD Fuel should only be used where
extended arctic conditions below (0°F/-18°C)
exist.
NOTE:
Use of Climatized ULSD Fuel or Number 1 ULSD
Fuel results in a noticeable decrease in fuel
economy.
Climatized ULSD Fuel is a blend of Number 2
ULSD and Number 1 ULSD Fuels which reduces
the temperature at which wax crystals form in
fuel.
The fuel grade should be clearly marked on the
pump at the fuel station.
The engine requires the use of ULSD Fuel. Use
of incorrect fuel could result in engine and
exhaust system damage Ú page 469.
If Climatized or diesel Number 1 ULSD Fuel is
not available, and you are operating below
(20°F/-6°C), in sustained arctic conditions,
Mopar® Premium Diesel Fuel Treatment (or
equivalent) is recommended to avoid gelling
(see Fuel Operating Range Chart).
Engine Oil Usage
For the correct engine oil viscosity Ú page 473.

STARTING AND OPERATING147
Winter Front Cover

Winter Front Cover

A Winter front or cold weather cover can be used in
ambient temperatures below 32°F (0°C),
especially during extended idle conditions. This
cover is equipped with four flaps for managing
total grille opening in varying ambient
temperatures. If a Winter front or cold weather
cover is to be used the flaps should be in the full
open position to allow air flow to the cooling
module and automatic transmission oil cooler.
When ambient temperatures drop below 0°F
(-17°C) the four flaps need to be closed. A suitable
cold weather cover is available from a Mopar®
dealer.
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.
If temperatures are below 32°F (0°C), operate the
engine at moderate speeds for five minutes before
full loads are applied.
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, cylinder head valves, turbochargers,
and injector nozzles. Also, the unburned fuel can
enter the crankcase, diluting the oil and causing
rapid wear to the engine.

STARTING AND OPERATING149
Do Not Operate The Engine With Low Oil
Pressure
If the Low Oil Pressure Warning Light turns on while
driving, stop the vehicle and shut down the engine
as soon as possible. After the vehicle is safely
stopped, restart the engine and monitor the lamp.
If the lamp is still illuminated, shut the engine off,
contact an authorized dealer, and do not operate
the vehicle until the cause is corrected. If the lamp
is no longer illuminated, the engine can be
operated, but should be taken to an authorized
dealer as soon as possible for further inspection.
NOTE:Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is
in the engine. The engine oil level must be checked
under the hood.
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the
parts fail. Some important observations 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

Engine Block Heater Cord Location
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 electrical outlet with a grounded,
three-wire extension cord.
For diesel engines, its use is recommended for
environments that routinely fall below -10°F
(-23°C). It should be used when the vehicle has not
been running for long periods of time and should
be plugged in two hours prior to start. Its use is
required for cold starts with temperatures under
-20°F (-28°C).
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
The engine block heater cord is routed under the
hood on the passenger side of the vehicle next to
the engine coolant reservoir.
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.WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

150STARTING AND OPERATING
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration within
the limits of local traffic laws contributes to a good
break-in. Wide-open throttle acceleration in low
gear can be detrimental and should be avoided.
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur. For the recommended viscosity and
quality grades Ú page 473.
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as a problem. Please check
your oil level with the engine oil indicator often
during the break-in period. Add oil as required.
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE
The diesel engine does not require a break-in
period due to its construction. Normal operation is
allowed, providing the following recommendations
are followed:
Warm up the engine before placing it under
load.
Do not operate the engine at idle for prolonged
periods.
Observe vehicle oil pressure and temperature
indicators.
Check the coolant and oil levels frequently.
Vary throttle position at highway speeds when
carrying or towing significant weight.
NOTE:Light duty operation such as light trailer towing or
no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy
and power may be seen at this time. The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur. For the recommended viscosity and
quality grades Ú
page 473.
NOTE:NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
Your vehicle is equipped with an EPB that offers
simple operation, and some additional features
that make the parking brake more convenient and
useful.
The parking brake is primarily intended to prevent
the vehicle from rolling while parked. Before
leaving the vehicle, make sure that the parking
brake is applied. Also, be certain to leave the
transmission in PARK.
You can engage the parking brake in two ways:
Manually, by applying the parking brake switch.
Automatically, by enabling the Auto Park Brake
feature in the Customer Programmable
Features section of the Uconnect settings.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.
