2018 Ram 2500 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.

depending on the nature of the problem.
Cycle the ignition when the vehicle is safely
and completely stopped and the transmission
is placed in the PARK position. The light
should turn off. If the light remains on with
the vehicle running, your vehicle will usually
be drivable; however, see an authorized
dealer for service as soon as possible.
NOTE:
This light may turn on if the accelerator and
brake pedals are pressed at the same time.
If the light continues to flash when the ve-
hicle is running, immediate service is re-
quired and you may experience reduced per-
formance, an elevated/rough idle, or engine
stall and your vehicle may require towing.
The light will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN posi-
tion and remain on briefly as a bulb check. If
the light does not come on during starting,
have the system checked by an authorized
dealer.— Electric Power Steering Fault

Yellow Warning Lights
— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
The light will illuminate when the ignition is
in the ON/RUN position before engine start.
If the bulb does not come on when turning
the ignition switch from OFF to ON/RUN,
have the condition checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe

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

ENGINE BREAK-IN
RECOMMENDATIONS — 3.0L DIESEL
The diesel engine does not require a break-in
period due to its construction. Normal opera-
tion is allowed, providing the following rec-
ommendations are followed:
• 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. The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. The
recommended viscosity and quality grades
are shown under “Fluids And Lubricants” in
"Technical Specifications” in this manual.
NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
ENGINE BREAK-IN
RECOMMENDATIONS — 6.7L DIESEL
The Cummins turbocharged diesel engine
does not require a break-in period due to its
construction. Normal operation is allowed,
providing the following recommendations are
followed:
• Warm up the engine before placing it under
load.
• 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
Operating” of the Owner’s Manual.
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).STARTING AND OPERATING
154

NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the LOCK/OFF (key removal) posi-
tion. The key fob can only be removed from
the ignition when the ignition is in the LOCK/
OFF position, and the transmission is locked
in PARK whenever the ignition is in the
LOCK/OFF position.
NOTE:
If a malfunction occurs, the system will trap
the key fob in the ignition to warn you that
this safety feature is inoperable. The engine
can be started and stopped but the key fob
cannot be removed until you obtain service.
Brake/Transmission Shift
Interlock System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock System (BTSI) that
holds the transmission gear selector in PARKunless the brakes are applied. To shift the
transmission out of PARK, the ignition must
be turned to the ON/RUN mode (engine run-
ning, for vehicles with eight-speed transmis-
sion) and the brake pedal must be pressed.
In 8-speed vehicles, the brake pedal must
also be pressed to shift from NEUTRAL into
DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.
Eight-Speed Automatic
Transmission — If Equipped
The transmission is controlled using a rotary
electronic gear selector located on the instru-
ment panel. The transmission gear range
(PRND) is displayed both above the gear
selector and in the instrument cluster. To
select a gear range, simply rotate the gear
selector. You must press the brake pedal to
shift the transmission out of PARK (or NEU-
TRAL, when the vehicle is stopped or moving
at low speeds). To shift past multiple gear
ranges at once (such as PARK to DRIVE),
simply rotate the gear selector to the appro-
priate detent. Select the DRIVE range for
normal driving. NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects PARK while
driving), the position indicator will blink con-
tinuously until the selector is returned to the
proper position, or the requested shift can be
completed.
The electronically-controlled transmission
adapts its shift schedule based on driver
inputs, along with environmental and road
conditions. The transmission 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 po-
sitions. Manual downshifts can be made us-
ing the Electronic Range Select (ERS) shiftSTARTING AND OPERATING
156

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. Pressing the ERS (-/+)
switches (column shift) or moving the gear
selector to the left or right (-/+) (console shift)
while in the DRIVE position will select the
highest available transmission gear, and will
display that gear limit in the instrument clus-
ter as 1, 2, 3, etc. Refer to "Electronic Range
Select (ERS) Operation" in this section for
further information. Some models will dis-
play both the selected 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
damage, Transmission Limp Home Mode is
activated. In this mode, the transmission re-
mains in direct gear regardless of which for-
ward gear is selected. PARK, REVERSE, and
NEUTRAL will continue to operate. The Mal-
function Indicator Light (MIL) may be illumi-
nated. 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 theproblem 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.
If the transmission cannot be reset, autho-
rized dealer service is required.
Electronic Range Select (ERS) Operation —
Six-Speed Transmission (1500 Models
Only)
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.
Use of ERS (or TOW/HAUL mode) also en-
ables an additional underdrive gear which is
not normally used during through-gear accel-
erations. This additional gear can improve
vehicle performance and cooling capability
when towing a trailer on certain grades. In
