2019 RAM CHASSIS CAB instrument cluster

STARTING AND OPERATING 351
Repeat steps 8 and 9 until the GAIN setting is at a point just below trailer wheel lockup. If towing a heavier trailer, trailer wheel
lockup may not be attainable even with the maximum GAIN setting of 10.
* The suggested selection depends and may change
depending on the customer preferences for braking perfor -
mance. Condition of the trailer brakes, driving and road state
may also affect the selection.
Display Messages
The trailer brake control interacts with the instrument cluster
display. Display messages, along with a single chime, will be
displayed when a malfunction is determined in the trailer
connection, trailer brake control, or on the trailer. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information. Light Electric Heavy Electric Light EOH Heavy EOH

ITBM system may result in reduced or complete loss of
trailer braking. There may be a increase in stopping
distance or trailer instability which could result in
personal injury.

SERVICING AND MAINTENANCESCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change indicator
system. The oil change indicator system will remind you that it
is time to take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil change indi -
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km) since
last reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a sched -
uled oil change is performed by someone other than your autho -
rized dealer, the message can be reset by referring to the steps
described under “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information. Gasoline Engines:
Under no circumstances should oil change intervals exceed
8,000 miles (13,000 km), twelve months or 350 hours of
engine run time, whichever comes first. The 350 hours of
engine run or idle time is generally only a concern for fleet
customers.
Severe Duty:
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
very low engine RPM’s. This type of vehicle use is consid -
ered Severe Duty.

440 SERVICING AND MAINTENANCE
Fluid Level Check — Eight-Speed Transmission
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis -
sion has no dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission malfunction, visit
an authorized dealer immediately to have the transmission
fluid level checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage. Fluid Level Check — Six-Speed Transmission
It is best to check the fluid level when the transmission is at
normal operating temperature (158-176°F / 70-80°C). This
normally occurs after at least 15 miles (25 km) of driving. At
normal operating temperature the fluid cannot be held
comfortably between the fingertips. You can read the trans -
mission sump temperature in the instrument cluster screen
(refer to “Instrument Cluster Display” for further informa -
tion).
Use the following procedure to check the transmission fluid
level properly:
1. Monitor the transmission temperature using the instru -
ment cluster display, and operate the vehicle as required
to reach the normal operating temperature. If the trans -
mission is not functioning properly, or the vehicle cannot
be driven, see the NOTE and CAUTION below about
checking the fluid level at colder temperatures.
2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60
seconds, and leave the engine running for the rest of this
procedure.
4. Fully apply the parking brake, and press the brake pedal.CAUTION!
Do not use chemical flushes in your transmission as the
chemicals can damage your transmission components.
Such damage is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to adjust
the fluid level accurately.

468 SERVICING AND MAINTENANCE
(Continued)NOTE:
If your vehicle is equipped with a Tire Pressure Information
System (TPIS):
• The Tire Pressure Information System (TPIS) uses unique
sensors in the inner rear wheels to help identify them from
the outer rear wheels, because of this, the inner and outer
wheel locations can’t be switched.
• After a tire rotation is completed, as shown below, the
system can auto learn the locations of each sensor ID. Auto
learning/localization occurs when the vehicle ignition
status is changed from Off to On and speeds of greater
than 5 mph (8km/h) are obtained and remain over 5mph
(8km/h) for at about a 15 minute period. You may need to
drive for 20 minutes to account slower speeds and stops.
• If the tires are rotated incorrectly, the Auto localization of
the TPIS sensors will fail to locate correctly resulting in
incorrect locations for the pressure values displayed in the
Instrument Cluster. DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire's manufacturer
in each category is shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform to Federal safety
requirements in addition to these grades.CAUTION!
• 4500/5500 Dual Rear Tires may only have one approved
direction of rotation. This is to accommodate the asym -
metrical design (tread pattern) of the On/Off road tire. • When replacing a flat, the spare tire may have to be
remounted on the rim or installed at a different location
to maintain the correct placement of the tire on the
wheel relative to the tire/wheel position on the vehicle.
For example, if the spare is used to replace an outer rear
tire it will have to be remounted on the rim so that the
wheel is dished inward. That way the tread design of
asymmetrical tires will maintain proper position. CAUTION! (Continued)

SERVICING AND MAINTENANCE 473
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical solvents
or abrasive cleaners. This will weaken the fabric. Sun
damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or luke -
warm water. Do not remove the belts from the vehicle to
wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
NOTE:
If the belts retract slowly, inspect the upper turning loop for
soiling. If soiling is present, clean with a wet soft cloth until
all residue is removed. Plastic And Coated Parts
Use Mopar Total Clean to clean vinyl upholstery.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care must
be taken to avoid scratching the plastic.
1. Clean with a wet soft cloth. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp
cloth.
2. Dry with a soft cloth.WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do not
disassemble or modify the system. Seat belt assemblies
must be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing, etc.). CAUTION!
• Direct contact of air fresheners, insect repellents,
suntan lotions, or hand sanitizers to the plastic,
painted, or decorated surfaces of the interior may cause
permanent damage. Wipe away immediately.
• Damage caused by these type of products may not be
covered by your New Vehicle Limited Warranty.
