maintenance reset RAM CHASSIS CAB 2021 Owners Manual

102GETTING TO KNOW YOUR INSTRUMENT PANEL
Your vehicle has the ability to alert you to
additional maintenance required on your
vehicle or engine. The following messages may
display in your instrument cluster display:

Perform Service — Your vehicle will require
emissions maintenance at a set interval.
To help remind you when this maintenance
is due, the instrument cluster display will
display “Perform Service”. When the “Perform
Service” message is displayed in the instru -
ment cluster display it is necessary to have the
emissions maintenance performed. Emissions
maintenance may include replacing the
Closed Crankcase Ventilation (CCV) filter
element. The procedure for clearing and reset -
ting the "Perform Service" indicator message is
located in the appropriate Service Information.
Exhaust System — Regeneration Required
Now — "Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy" will be displayed
in the instrument cluster display if the exhaust
particulate filter reaches 80% of its maximum
storage capacity. Under conditions of exclu -
sive short duration and low speed driving
cycles, your Cummins diesel engine and
exhaust after-treatment system may never
reach the conditions required to remove the
trapped PM. If this occurs, the “Exhaust Filter
XX% Full Safely Drive at Highway Speeds to
Remedy” message will be displayed in the
instrument cluster display. If this message is
displayed, you will hear one chime to assist in
alerting you of this condition

By simply driving your vehicle at highway
speeds for as little as 45 minutes, you can
remedy the condition in the particulate filter
system and allow your Cummins diesel
engine and exhaust after-treatment system
to remove the trapped PM and restore the
system to normal operating condition.Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — Indicates that the
DPF is self-cleaning. Maintain your current
driving condition until regeneration is
completed.

Exhaust System — Regeneration Completed —
This message indicates that the DPF
self-cleaning is completed. If this message is
displayed, you will hear one chime to assist in
alerting you of this condition.
Exhaust Service Required — See Dealer
Now — This message indicates regeneration
has been disabled due to a system malfunc -
tion. At this point the engine Powertrain
Control Module (PCM) will register a fault code,
the instrument panel will display a MIL light.

WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.
CAUTION!
See an authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.

STARTING AND OPERATING213
The loaded vehicle weight, including the
snowplow system, all aftermarket accessories,
driver, passengers, options, and cargo, must
not exceed either the Gross Vehicle Weight
Rating (GVWR) or Gross Axle Weight Rating
(GAWR). These weights are specified on the
Safety Compliance Certification Label on the
driver's side door opening.
NOTE:
Detach the snowplow when transporting
passengers.

Vehicle front end wheel alignment was
set to specifications at the factory without
consideration for the weight of the plow.
Front end toe-in should be checked and reset
if necessary at the beginning and end of the
snowplow season. This will help prevent uneven
tire wear.

The blade should be lowered whenever the
vehicle is parked.

Maintain and operate your vehicle and snowplow
equipment following the recommendations
provided by the specific snowplow manufacturer.
OVER THE ROAD OPERATION WITH
S
NOWPLOW ATTACHED

The blade restricts air flow to the radiator and
causes the engine to operate at higher than
normal temperatures. Therefore, when
transporting the plow, angle the blade completely
and position it as low as road or surface
conditions permit. Do not exceed 40 mph
(64 km/h). The operator should always maintain
a safe stopping distance and allow adequate
passing clearance.

OPERATING TIPS
Under ideal snow plowing conditions, 20 mph
(32 km/h) should be maximum operating
speed. The operator should be familiar with the
area and surface to be cleaned. Reduce speed
and use extreme caution when plowing
unfamiliar areas or under poor visibility.
GENERAL MAINTENANCE
Snowplows should be maintained in
accordance with the plow manufacturer's
instructions.
Keep all snowplow electrical connections and
battery terminals clean and free of corrosion.
When plowing snow, to avoid transmission and
drivetrain damage, the following precautions
should be observed.
Operate with transfer case in 4L when
plowing small or congested areas where
speeds are not likely to exceed 15 mph
(24 km/h). At higher speeds operate in
4WD High.
Vehicles with automatic transmissions
should use 4WD Low range when plowing
deep or heavy snow for extended periods of
time to avoid transmission overheating.
Do not shift the transmission unless the
engine has returned to idle and wheels have
stopped. Make a practice of stepping on the
brake pedal while shifting the transmission.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
ENGINE
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 indicator 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. Have your vehicle serviced
as soon as possible, within the next 500 miles
(805 km).
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change.
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
12 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.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look
for unusual wear or damage. Rotate at the
first sign of irregular wear.
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and
automatic transmission (six-speed only), and
fill as needed.

Check function of all interior and exterior lights.

358SERVICING AND MAINTENANCE
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer Úpage 90.
Replace the engine oil and oil filter every
15,000 miles (24,000 km) or 12 months, or sooner if prompted by the oil change indicator
system. Under no circumstances should oil
change intervals exceed 15,000 miles
(24,000 km) or 12 months, whichever
comes first.
NOTE:
Under no circumstances should oil change
intervals exceed 15,000 miles (24,000 km)
or 12 months or 500 Hours, whichever
comes first.
Replace the engine oil and oil filter every
12,500 miles (20,000 km) or 400 hours,
whichever comes first when running greater
than 5% levels of biodiesel (Chassis Cab
models configured with optional B20 capa -
bility).
If Chassis Cab models configured with optional
B20 capability are operated with greater than
5% levels of biodiesel, the oil change interval
must not exceed 12,500 miles (20,000 km) or
400 hours, whichever comes first under any
circumstances. See the Fuel Requirements
section for more information regarding
operation with biodiesel blend (B6-B20) fuel
meeting ASTM specification D-7467.PERFORM SERVICE INDICATOR —

388SERVICING 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 transmission 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 transmission sump
temperature in the instrument cluster screen
Ú page 90. Use the following procedure to check the
transmission fluid level properly:

1. Monitor the transmission temperature
using the instrument cluster display, and
operate the vehicle as required to reach
the normal operating temperature. If the
transmission 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.
5. Place the gear selector momentarily into each gear position (allowing time for the
transmission to fully engage in each
position), ending with the transmission in
PARK.
6. Remove the dipstick, wipe it clean and reinsert it until seated.
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.
