In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized dealer
service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the
transmission is in DRIVE. For example, if you set the
transmission gear limit to 4 (fourth gear), the transmis-
sion will not shift above fourth gear, but will shift
through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the ERS (-)
switch will activate ERS mode, display the current gear in
the instrument cluster, and set that gear as the top
available gear. Once in ERS mode, tapping the ERS (-) or
(+) switch will change the top available gear.

•Brake pedal must not be applied.
• No vehicle, brake or clutch switch faults present.
• Vehicle engine must be running.
• PTO must be correctly installed using the vehicle
provided circuits.
The customer may choose to use the PTO while the
vehicle is moving. To do so, the PTO function must be
activated prior to taking the vehicle out of PARK. This is
accomplished by activating the upfitter-provided PTO
on/off switch. At this point, the customer may place the
vehicle in a forward or reverse gear and have PTO
operation once the vehicle begins to move. To disengage
PTO operation and return to “standard vehicle opera-
tion” simply toggle the on/off switch to the OFF position. NOTE:
For application specific information with respect
to PTO and pump requirements and additional vehicle
information (wiring schematics, preset idle values, en-
gine speed limits, and vehicle hardware and software
requirements) please refer to the Body Builders Guide by
accessing www.rambodybuilder.com and choosing the
appropriate links.
ENGINE RUNAWAY
Diesel engine runaway is a rare condition affecting diesel
engines, where the engine consumes its own lubrication
oil and runs at higher and higher RPM until it overspeeds
to a point where it destroys itself due to either mechani-
cal failure or engine seizure through lack of lubrication.

“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 and
Pickup models configured with optional B20 capability
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.
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 and Pickup 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) under any circum-
stances. See the Fuel Requirements section for more

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.
