service schedule Ram 1500 2015 Diesel Supplement

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
MAINTAINING YOUR VEHICLE 309

Required Maintenance For Noise Control Systems
The following maintenance services must be performed
every six months or 7,500 miles (12 000 km) whichever
comes first, to assure proper operation of the noise
control systems. In addition, inspection and service
should be performed anytime a malfunction is observed
or suspected. Proper maintenance of the entire vehicle
will help the effectiveness of the noise control systems.
Exhaust System
Inspect the entire exhaust system for leaks and damaged
parts. Devices such as hangers, clamps, and U-bolts
should be tight and in good condition. Damaged compo-
nents, burned or blown out mufflers, burned or rusted
out exhaust pipes should be replaced according to the
procedures and specifications outlined in the appropriate
service manual.Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and that the cover is tight. Check all hoses leading to the
air cleaner for tightness. The air filter element must also
be clean and serviced according to the instructions out-
lined in the Maintenance Schedule section of this manual.
Tampering With Noise Control System Prohibited
Federal law prohibits the following acts or the causing
thereof: (1) the removal or rendering inoperative by any
person, other than for purposes of maintenance, repair, or
replacement, of any device or element of design incorpo-
rated into any new vehicle for the purpose of noise
control prior to its sale or delivery to the ultimate
purchaser or while it is in use, or (2) the use of the vehicle
after such device or element of design has been removed
or rendered inoperative by any person.

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.

MAINTENANCE SCHEDULE 323

NOTE:
•Under no circumstances should oil change intervals
exceed 15,000 miles (24,000 km) or six months or 500
Hours, whichever comes first.
• Replace the engine oil and oil filter every 12,500 miles
(20 000 km) when running B20 fuel (Chassis Cab
Only).
If Chassis Cab models are operated with greater than 5%
levels of Biodiesel, the oil change interval must not
exceed 12,500 miles (20 000 km) under any circumstances.
See the Fuel Requirements section for more information
regarding operation of Chassis Cab models configured
for use with Biodiesel blend (B6-B20) fuel meeting ASTM
specification D-7467.Perform Service Indicator — Cummins® Diesel
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is
due, the Electronic Vehicle Information Center (EVIC) or
Driver information Display (DID) will display “Perform
Service”. When the “Perform Service” message is dis-
played on the EVIC/DID it is necessary to have the
emissions maintenance performed. Emissions mainte-
nance may include replacing the Closed Crankcase Ven-
tilation (CCV) filter element. The procedure for clearing
and resetting the “Perform Service” indicator message is
located in the appropriate Service Information.
