2018 Ram 4500 Chassis Cab manual transmission

Memory Position Recall
NOTE:
• For vehicles equipped with an automatictransmission, the vehicle speed must be
lower than 5 mph to recall memory posi-
tions. If a recall is attempted when the
vehicle speed is greater than 5 mph, a
message will be displayed in the instru-
ment cluster display.
• For vehicles equipped with a manual trans- mission, the vehicle speed must be at
0 mph (0 km/h) to recall memory positions.
If a recall is attempted with the vehicle
speed above 0 mph (0 km/h), a message
will appear in the instrument cluster
display.
Driver One Memory Position Recall
• To recall the memory settings for driver one using the memory switch, push memory
button (1) on the memory switch.
• To recall the memory settings for driver one using the key fob, push the unlock button
on the key fob linked to memory position 1. Driver Two Memory Position Recall
• To recall the memory setting for driver two
using the memory switch, push memory
button (2) on the memory switch.
• To recall the memory settings for driver two using the key fob, push the unlock button
on the key fob linked to memory position 2.
A recall can be cancelled by pushing any of
the memory buttons during a recall (S, 1, or
2). When a recall is cancelled, the driver's
seat and the power pedals (if equipped) stop
moving. A delay of one second will occur
before another recall can be selected.
Easy Entry/Exit Seat
This feature provides automatic driver’s seat
positioning to enhance driver mobility when
entering and exiting the vehicle.
The distance the driver’s seat moves depends
on where you have the driver’s seat positioned
when you remove the key fob from the igni-
tion (or change the ignition to OFF, for ve-
hicles equipped with Keyless Enter-N-Go). • When you remove the key fob from the
ignition (or change the ignition to OFF, for
vehicles equipped with Keyless Enter-N-
Go), the driver’s seat will move about
2.4 inches (60 mm) rearward if the driver’s
seat position is greater than or equal to
2.7 inches (67.7 mm) forward of the rear
stop. The seat will return to its previously
set position when you place the ignition
into the ACC or RUN position.
• When you remove the key fob from the ignition (or change the ignition to OFF, for
vehicles equipped with Keyless Enter-N-
Go), the driver’s seat will move to a position
0.3 inches (7.7 mm) forward of the rear
stop if the driver’s seat position is between
0.9 inches and 2.7 inches (22.7 mm and
67.7 mm) forward of the rear stop. The seat
will return to its previously set position
when you place the ignition to the ACC or
RUN position.
• The Easy Entry/Easy Exit feature is disabled when the driver’s seat position is less than
0.9 inches (22.7 mm) forward of the rear
stop. At this position, there is no benefit to
the driver by moving the seat for Easy Exit
or Easy Entry.

for further information.
The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay po-
sition 1 is the least sensitive, and wiper delay
position 5 is the most sensitive. Position
3 should be used for 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 silicone may reduce Rain Sensing
performance.
The Rain Sensing system has protection fea-
tures for the wiper blades and arms, and will
not operate under the following conditions:
• Low Ambient Temperature — When the igni-
tion is first turned ON, 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 tem-
perature 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 opera-
tion can resume, if it has been selected,
and no other inhibit conditions (mentioned
previously) exist.

on, turn it off. Also, shift the transmission
into NEUTRAL and idle the vehicle. If the
temperature reading does not return to nor-
mal, turn the engine off immediately and call
for service. Refer to “If Your Engine Over-
heats” in “In Case Of Emergency” for further
information.
— Oil Pressure Warning Light
This light indicates low engine oil pressure. If
the light turns on while driving, stop the
vehicle and shut off the engine as soon as
possible. A chime will sound when this light
turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
— Oil Temperature Warning Light
This telltale indicates engine oil temperature
is high. If the light turns on while driving,
stop the vehicle and shut off the engine as
soon as possible. Wait for oil temperature to

to maintain normal system voltage by auto-
matically increasing engine idle speed. You
may notice several consecutive increases in
idle speed, up to a maximum of 1450 RPM,
as the system will attempt to utilize the
smallest increase in idle speed necessary to
maintain normal system voltage. The idle
speed will return to normal when either the
electrical load is removed, or when the brake
pedal is applied.
NOTE:
For instrument cluster display messages re-
lated to the vehicle's exhaust system, refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further in-
formation.
Idle-Up Feature — Automatic Transmission
Only
The driver-controlled high idle speed feature
will help increase cylinder temperatures and
provide additional cab heat, however, exces-
sive idling may still cause the exhaust after-
treatment system to not properly regenerate.
Extended periods of idle time should be
avoided.The Idle-Up feature uses the speed control
switches to increase engine idle speed and
quickly warm the vehicle's interior.
1. With the transmission in PARK, the park-
ing brake applied, and the engine run-
ning, push the speed control switch to the
ON position, then push the SET switch.
2. The engine RPM will go up to 1100 RPM. To increase the RPM, push and hold the
ACCEL/RESUME switch and the idle
speed will increase to approximately
1500 RPM. To decrease the RPM, push
and hold the DECEL switch and the idle
speed will decrease to approximately
1100 RPM.
3. To cancel the Idle–Up feature, either push the CANCEL switch, push the ON/OFF
switch, or press the brake pedal.Stopping The Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricat- ing oil and coolant to carry excess heat away
from the combustion chamber, bearings, in-
ternal components, and turbocharger. This is
especially important for turbocharged,
charge air-cooled engines.
NOTE:
• During engine shut down on vehicles
equipped with manual transmissions, it is
normal for the diesel engine to resonate
heavily for a moment during engine shut
off. When the engine is connected to a
manual transmission, this resonance
causes load gear rattle from the transmis-
sion. This is commonly referred to as “shut
down rattle.” The manufacturer recom-
mends performing engine shut down with
the clutch pedal pushed to the floor (clutch
disengaged). When engine shut down is
performed in this manner the rattle is re-
duced (not eliminated).
• Refer to the following chart for proper en- gine shutdown.
STARTING AND OPERATING
126

• Warm up the engine before placing it underload.
• Do not operate the engine at idle for pro- longed periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and tempera- ture indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer
towing or no load operation will extend the
time before the engine is at full efficiency.
Reduced fuel economy and power may be
seen at this time.
For additional vehicle break-in requirements,
refer to “Trailer Towing” in “Starting And Oper-
ating” of the Owner’s Manual at
www.mopar.com/en-us/care/
owners-manual.html (U.S. Residents) or
www.owners.mopar.ca (Canadian Residents). Because of the construction of the Cummins
turbocharged diesel engine, engine run-in is
enhanced by loaded operating conditions
which allow the engine parts to achieve final
finish and fit during the first 6,000 miles
(10 000 km).
AUTOMATIC TRANSMISSION
WARNING!
• 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
reverse. 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.
• Unintended movement of a vehicle
could injure those in or near the vehicle.
As with all vehicles, you should never
exit a vehicle while the engine is run-
ning. Before exiting a vehicle, always
come to a complete stop, then apply the
WARNING!
parking brake, shift the transmission
into PARK, turn the engine OFF, and
remove the key fob. When the ignition is
in the LOCK/OFF (key removal) position,
(or, with Keyless Enter-N-Go, when the
ignition is in the OFF mode) the trans-
mission is locked in PARK, securing the
vehicle against unwanted movement.
• When leaving the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
• Never use the PARK position as a sub-
stitute for the parking brake. Always
apply the parking brake fully when exit-
ing the vehicle to guard against vehicle
movement and possible injury or dam-
age.
• 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 exiting the vehicle.
STARTING AND OPERATING
128

The transmission gear position display (lo-
cated in the instrument cluster) indicates the
transmission gear range. The gear selector is
mounted on the right side of the steering
column. You must press the brake pedal to
move the gear selector out of PARK (refer to
“Brake/Transmission Shift Interlock System”
in this section). To drive, move the gear
selector from PARK or NEUTRAL to the
DRIVE position. Pull the gear selector toward
you when shifting into REVERSE or PARK, or
when shifting out of PARK.
The electronically-controlled transmission
provides a precise shift schedule. The trans-
mission electronics are self-calibrating;
therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal
condition, and precision shifts will develop
within a few hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and
the vehicle is stopped. Be sure to keep your
foot on the brake pedal when shifting be-
tween these gears.The transmission gear selector has only
PARK, REVERSE, NEUTRAL, and DRIVE
shift positions. Manual downshifts can be
made using the Electronic Range Select
(ERS) shift control. Pushing the ERS (-/+)
switches (on the gear selector) while in the
DRIVE position will select the highest avail-
able transmission gear, and will display that
gear limit in the instrument cluster as 1, 2, 3,
etc. Refer to "Electronic Range Select (ERS)
Operation" in this section for further informa-
tion. Some models will display both the se-
lected gear limit, and the actual current gear,
while in ERS mode.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains
in fourth gear (for 66RFE transmission) or third
gear (for AS66RC/AS69RC transmission) re-
gardless of which forward gear is selected. If an
AS66RC/AS69RC equipped truck enters Limp
Home Mode at highway speeds, it will initially
engage fifth gear, until the vehicle slows to a speed where third gear can be engaged. PARK,
REVERSE, and NEUTRAL will continue to op-
erate. The Malfunction Indicator Light (MIL)
may be illuminated. Limp Home Mode allows
the vehicle to be driven to an authorized dealer
for service without damaging the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all for-
ward gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the trans-
mission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible convenience.
Your authorized dealer has diagnostic equip-
ment to assess the condition of your trans-
mission.
STARTING AND OPERATING
130

If the transmission cannot be reset, autho-
rized dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift con-
trol allows the driver to limit the highest
available gear when the transmission is in
DRIVE. For example, if you set the transmis-
sion gear limit to 4 (fourth gear), the trans-
mission 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 gear
selector is in the DRIVE position, the trans-
mission 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 (-) 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 ve-
hicle could skid, causing a collision or
personal injury.
NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), simply
push and hold the ERS (-) switch. The trans-
mission 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 overspeed.
FOUR-WHEEL DRIVE OPERATION —
IF EQUIPPED
• Four-wheel drive trucks are equipped with either a manually shifted transfer case or an
electronically shifted transfer case. Refer to
the operating instructions for electronic
transfer case, located in this section for
further information.
• For further information on the manually shifted transfer case, refer to “Four Wheel
Drive Operation” in “Starting And Operat-
ing” in your Owner’s Manual located at

shown is dependent on the selected speed
unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET (-) button once will resultin a 1 mph decrease in set speed. Each
subsequent tap of the button results in a
decrease of 1 mph.
• If the button is continually pushed, the set speed will continue to decrease until the
button is released, then the new set speed
will be established.
Metric Speed (km/h)
• Pushing the SET (-) button once will result in a 1 km/h decrease in set speed. Each
subsequent tap of the button results in a
decrease of 1 km/h.
• If the button is continually pushed, the set speed will continue to decrease until the
button is released, then the new set speed
will be established.To Accelerate For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:
The Speed Control system maintains speed
up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain
may occur so it may be preferable to drive
without Speed Control.
WARNING!
Speed Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the con-
ditions, and you could lose control and
have an accident. Do not use Speed Con-
trol in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the
RES (+) button and release. Resume can be
used at any speed above 20 mph (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the
CANCEL button, or normal brake pressure
while slowing the vehicle will deactivate the
Speed Control without erasing the set speed
from memory.
Pushing the ON/OFF button or turning the
ignition switch OFF erases the set speed from
memory.
