2019 Ram 4500 Chassis Cab oil

SAFETY 241
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the exhaust
system each time the vehicle is raised for lubrication or oil
change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision if
they have been damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt or retractor
condition, replace the seat belt.Air Bag Warning Light
The Air Bag warning light will turn on for four to eight
seconds as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on during
starting, stays on, or turns on while driving, have the system
inspected at an authorized dealer as soon as possible. After
the bulb check, this light will illuminate with a single chime
when a fault with the Air Bag System has been detected. It
will stay on until the fault is removed. If the light comes on
intermittently or remains on while driving, have an autho
-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
Defroster
Check operation by selecting the defrost mode and place the
blower control on high speed. You should be able to feel the
air directed against the windshield. See an authorized dealer
for service if your defroster is inoperable.

SAFETY 243
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected immediately.
• ALWAYS make sure objects cannot fall or slide into the
driver’s side floor area when the vehicle is moving.
Objects can become trapped under accelerator, brake,
or clutch pedals and could cause a loss of vehicle
control.
• NEVER place any objects under the floor mat (e.g., towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed, always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat.

STARTING AND OPERATING 251
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a stan-
dard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
Gasoline Engine Only
The engine block heater cord is routed through the grille by
the right front tow hook.
It includes a removable cap that is secured by a tethered
strap. It also has a c-clip that is used for storage when not in
use for the Winter months. During Winter months, remove
the heater cord wiring assembly from itself on the c-clip.
The engine block heater must be plugged in at least one hour
to have an adequate warming effect on the engine.
ENGINE BREAK-IN RECOMMENDATIONS
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 detri -
mental 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 recom -
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.

252 STARTING AND OPERATING
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.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking brake
is fully applied. Also, be certain to leave the transmission in
PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park brake,
firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle.Parking Brake Release
When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
• When the parking brake is applied and the transmission is placed in gear, the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied. It does not show the degree of brake application.

STARTING AND OPERATING 365
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 water.
• Do not exceed 5 mph (8 km/h) when driving through standing water. This will minimize wave effects.
• Driving through standing water may cause damage to your vehicle’s drivetrain components. Always inspect
your vehicle’s fluids (i.e., engine oil, transmission, axle,
etc.) for signs of contamination (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.
