normal rain conditions. Positions 1 and 2 can be
used if the driver desires less wiper sensitivity.
Positions 4 and 5 can be used if the driver
desires more sensitivity. Place the wiper switch in
the O (off) position when not using the system.

NOTE:
The Rain Sensing feature will not operate
when the wiper switch is in the low or
high-speed position.
The Rain Sensing feature may not function
properly when ice, or dried salt water is
present on the windshield.

Use of Rain-X or products containing wax or sili -
cone may reduce Rain Sensing performance.
The Rain Sensing feature can be turned on and
off using the Uconnect system
Ú
page 228.

The Rain Sensing system has protection
features for the wiper blades and arms, and will
not operate under the following conditions:
Low Ambient Temperature — When the igni-
tion is first placed in the ON position, the Rain
Sensing system will not operate until the
wiper switch is moved, vehicle speed is
greater than 0 mph (0 km/h), or the outside
temperature is greater than 32°F (0°C).
Transmission In NEUTRAL Position — When
the ignition is ON, and the transmission is in
the NEUTRAL position, the Rain Sensing
system will not operate until the wiper switch
is moved, vehicle speed is greater than
5 mph (8 km/h), or the gear selector is
moved out of the NEUTRAL position.
Remote Start Mode Inhibit — On vehicles
equipped with Remote Starting system, Rain
Sensing wipers are not operational when the
vehicle is in the remote start mode. Once the
operator is in the vehicle and has placed the
ignition switch in the RUN position, Rain
Sensing wiper operation can resume, if it has
been selected, and no other inhibit condi -
tions (mentioned previously) exist.

POWER TAKE OFF (PTO) OPERATION — IF
EQUIPPED

This vehicle when equipped with PTO Prep and
the AS66RC/AS69RC automatic six-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 Bodybuilders web site:
https://

body-builders-guide.html
POWER STEERING
HYDRAULIC POWER STEERING
The standard power steering system will give
you good vehicle response and increased 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.
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.

TOWING TIPS
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, select TOW/HAUL mode or select a lower
gear range (using the Electronic Range Select
(ERS) shift control). NOTE:
Using TOW/HAUL mode or selecting a lower
gear range (using the ERS shift control) while
operating the vehicle under heavy loading
conditions will improve performance and
extend transmission life by reducing excessive
shifting and heat build-up. This action will also
provide better engine braking.
Six-Speed Automatic Transmission Only
When towing a loaded trailer up steep grades
at low speeds (20 mph [32 km/h] or below),
holding your vehicle in FIRST gear (using the
ERS shift control) can help to avoid
transmission overheating.
If you regularly tow a trailer for more than
45 minutes of continuous operation, then
change the automatic transmission fluid and
filter(s) as specified for "police, taxi, fleet, or
frequent trailer towing." Ú
page 354.
NOTE:
Check the automatic transmission fluid level
before towing (Six-speed automatic only).
