system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
Your vehicle has the ability to alert you to additional
maintenance required on your vehicle or engine. Refer to
the following messages that may be displayed on your DID:
•Perform Service— Your vehicle will require emissions
maintenance at a set interval. To help remind you when
this maintenance is due, the Cluster will display “Per-
form Service”. When the “Perform Service” message is
displayed on the DID it is necessary to have the emis-
sions maintenance performed. Emissions maintenance
may include replacing the Closed Crankcase Ventilation
(CCV) filter element. The procedure for clearing and
resetting 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 Cluster if
the exhaust particulate filter reaches 80% of its maxi-
mum storage capacity. Under conditions of exclusive
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 DID. 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 Cum-
mins® diesel engine and exhaust after-treatment sys-
tem to remove the trapped PM and restore the system
to normal operating condition.

approved ASTM standards, if stored properly, provides
for protection against fuel oxidation for up to six months.
Fuel Water Separation — Must Use MOPAR®/
Cummins® Approved Fuel Filter Elements
You must use MOPAR®/Cummins® approved fuel filter
elements in both your engine mounted filter and frame
mounted filter.
Biodiesel fuel has a natural affinity to water and water
accelerates microbial growth. Your MOPAR®/
Cummins® filtration system is designed to provide ad-
equate fuel water separation capabilities.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient tem-
peratures, which may pose problems for both storage and
operation. Precautions can be necessary at low ambienttemperatures, such as storing the fuel in a heated build-
ing or a heated storage tank, or using cold temperature
additives.
Fuel In Oil Dilution — Must Adhere To Required
Oil Change Interval
Fuel dilution of lubricating oil has been observed with
the use of Biodiesel fuel. Fuel in oil must not exceed 5%.
To ensure this limit is met your oil change interval must
be maintained to the following schedule:
•
Ram PickUp 2500/3500 Only — 15,000 Miles*
• Ram 3500/4500/5500 Chassis Cab — 12,500 Miles*
(*unless otherwise notified with a oil service message)
256 STARTING AND OPERATING

NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at 60-70°F / 16-21°C for 68RFE transmis-
sion, or 68-86°F / 20-30°C for AS69RC transmission. Only
use the COLD region of the dipstick as a rough reference
when setting the fluid level after a transmission service
or fluid change. Re-check the fluid level, and adjust as
required, once the transmission reaches normal operating
temperature.
CAUTION!
If the fluid temperature is below 50°F (10°C) it may
not register on the dipstick. Do not add fluid until
the temperature is elevated enough to produce an
accurate reading. Run the engine at idle, in PARK, to
warm the fluid. 8. Reinsert the dipstick. Check for leaks. Release the
parking brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated position, as long as its seal remains
engaged in the dipstick tube.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter(s) if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.6

Oil Change Indicator System — Cummins®
Diesel
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is
time to change your engine oil by displaying the words
“Oil Change Due” on your Electronic Vehicle Informa-
tion Center (EVIC) or Driver Information Display (DID).
The oil change reminder will remind the owner to change
the engine oil every 15,000 miles or 500 hours, whichever
comes first, except for the Chassis Cab models that are
using B20 biodiesel, which are 12,500 miles or 400 hours,
whichever comes first. Failure to change the engine oil
per the maintenance schedule can result in internal
engine damage.Your 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 your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
Replace the engine oil and oil filter every 15,000 miles
(24 000 km) or six 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 six months, whichever comes first.
