140 STARTING AND OPERATING
Care should be taken to avoid sudden
accelerations when both rear wheels are on a
slippery surface. This could cause both rear wheels
to spin, and allow the vehicle to slide sideways on
the crowned surface of a road or in a turn.
POWER TAKE OFF (PTO) OPERATION —
IF EQUIPPED
This vehicle when equipped with PTO Prep and the
AS66RC/AS69RC automatic 6-speed, will allow for
an aftermarket upfit with a transmission driven
PTO (power take off). The customer will have the
ability to operate the PTO in either a “stationary”,
“mobile” or “remote” mode. The vehicles will be
factory set to the “stationary” mode. To select a
different mode, or to change any other PTO setting,
you will need to enter the commercial vehicle
menu on the instrument cluster screen. Details of
the PTO selection modes and further PTO
information is available at the Ram Truck Body
Builder’s web site: https://www.ramtrucks.com/

HYDRAULIC POWER STEERING
The standard power steering system provides
increased vehicle response and ease of
maneuverability in tight spaces. The system will
provide mechanical steering capability if power
assist is lost.
If for some reason the power assist is interrupted,
it will still be possible to steer your vehicle. Under
these conditions, you will observe a substantial
increase in steering effort, especially at very low
vehicle speeds and during parking maneuvers.
NOTE:
Increased noise levels at the end of the steering
wheel travel are considered normal and do not
indicate that there is a problem with the power
steering system.
Upon initial start-up in cold weather, the power
steering pump may make noise for a short
amount of time. This is due to the cold, thick
fluid in the steering system. This noise should
be considered normal, and it does not in any
way damage the steering system.
POWER STEERING FLUID CHECK
Checking the power steering fluid level at a defined
service interval is not required. The fluid should
only be checked if a leak is suspected, abnormal
noises are apparent, and/or the system is not
functioning as anticipated. Check fluid level when
the engine is cold and off. Coordinate inspection
efforts through an authorized dealer.
WARNING!
On vehicles equipped with a limited-slip
differential never run the engine with one rear
wheel off the ground since the vehicle may drive
through the rear wheel remaining on the ground.
You could lose control of the vehicle.
CAUTION!
Prolonged operation of the steering system at
the end of the steering wheel travel will increase
the steering fluid temperature and it should be
avoided when possible. Damage to the power
steering pump may occur.
WARNING!
Fluid level should be checked on a level surface
and with the engine off to prevent injury from
moving parts and to ensure accurate fluid level
reading. Do not overfill. Use only manufacturer's
recommended power steering fluid.
