2017 RAM CHASSIS CAB wheel

Do Not Disturb
With Do Not Disturb, you can disable notifications from
incoming calls and texts, allowing you to keep your eyes
on the road and hands on the wheel. For your convenience,
there is a counter display to keep track of your missed calls
and text messages while you were using Do Not Disturb.
Do Not Disturb can automatically reply with a text mes-
sage, a call or both, when declining an incoming call and
send it to voicemail.
Automatic reply messages can be:
• “I am driving right now, I will get back to you shortly.”
• Create a custom auto reply message up to 160 characters.
NOTE: Only the first 25 characters can been seen on the
touchscreen while typing a custom message.
While in Do Not Disturb, Conference Call can be selected
so you can still place a second call without being inter-
rupted by incoming calls.
NOTE:
• Reply with text message is not compatible with iPhones.
• Auto reply with text message is only available on
phones that support Bluetooth MAP. General Information

NOTE: After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating. This
is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on
the transmission locking mechanism may make it difficult
to move the gear selector out of PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill grade.
NOTE: On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
When exiting the vehicle, always:
• Apply the parking brake. • Shift the transmission into PARK.
• Turn the engine OFF.
• Remove the key fob.
WARNING!• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before leav-
ing the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal. (Continued)328 STARTING AND OPERATING

instrument cluster, and set that gear as the top available
gear. Once in ERS mode, tapping (-) or (+) will change the
top available gear.
To exit ERS mode, simply push and hold the ERS (+) switch
until the gear limit display disappears from the instrument
cluster. WARNING!Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.
NOTE: To select the proper gear position for maximum
deceleration (engine braking), simply push and hold the
ERS (-) switch. The transmission will shift to the range
from which the vehicle can best be slowed down.
CAUTION!When using ERS for engine braking while descending
steep grades, be careful not to overspeed the engine.
Apply the brakes as needed to prevent engine over-
speed.
Overdrive Operation
The automatic transmission includes an electronically con-
trolled Overdrive (fifth and sixth gears). The transmission
will automatically shift into Overdrive if the following
conditions are present:
• The gear selector is in the DRIVE position.Column Gear Selector 5STARTING AND OPERATING 333

WARNING!Do not use the “TOW/HAUL” feature when driving in
icy or slippery conditions. The increased engine brak-
ing can cause the rear wheels to slide, and the vehicle
to swing around with the possible loss of vehicle
control, which may cause an accident possibly result-
ing in personal injury or death.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages. NOTE:
• The torque converter clutch will not engage (and 66RFE-
equipped trucks will not shift to sixth gear), until the
transmission fluid and engine coolant are warm [usually
after 1 to 3 miles (2 to 5 km) of driving]. Because engine
speed is higher when the torque converter clutch is not
engaged, it may seem as if the transmission is not
shifting properly when cold. This is normal. Using the
Electronic Range Select (ERS) shift control, when the
transmission is sufficiently warm, will demonstrate that
the transmission is able to shift into and out of Over-
drive.
• If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the transmis-
sion into gear may seem sluggish. This is due to the fluid
partially draining from the torque converter into the
transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds after starting the engine. 5STARTING AND OPERATING 335

• PTO must be correctly installed using the vehicle pro-
vided 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 accom-
plished 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 operation” 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, engine
speed limits, and vehicle hardware and software require-
ments) please refer to the Body Builders Guide by access-
ing rambodybuilder.com and choosing the appropriate
links. FOUR-WHEEL DRIVE OPERATION — IF EQUIPPED
Four-wheel drive trucks are equipped with either a manu-
ally shifted transfer case or an electronically shifted trans-
fer case. Refer to the operating instructions for your
transfer case, located in this section for further information.
Manually Shifted Transfer Case — If Equipped
The transfer case provides four mode positions:
• Two-Wheel Drive High Range (2H)
• Four-Wheel Drive Lock High Range (4H)
• Neutral (N)
• Four-Wheel Drive Low Range (4L)
For additional information on the appropriate use of each
transfer case mode position, see the information below:
2H
Two-Wheel Drive High Range — This range is for normal
street and highway driving on dry, hard surfaced roads.338 STARTING AND OPERATING
