keyless Ram 2500 2018 Owner's Manual

• A Diesel Pre-Heat system both improvesengine starting and reduces the amount of
white smoke generated by a warming
engine.
STARTING THE ENGINE — 6.7L
DIESEL ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belts.
The starter should not be operated for more
than 15-second intervals. Waiting a few min-
utes between such intervals will protect the
starter from overheating.
WARNING!
• Do not leave children or animals inside parked vehicles in hot weather. Interior
heat build up may cause serious injury
or death.
• When leaving the vehicle, always make
sure the keyless ignition node is in the
“OFF” mode, remove the key fob from
the vehicle and lock the vehicle.
WARNING!
• Never leave children alone in a vehicle,or with access to an unlocked vehicle.
Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A
child could operate power windows,
other controls, or move the vehicle.
Keyless Enter-N-Go — Ignition
This feature allows the driver to operate the
ignition switch with the push of a button, as
long as the Remote Start/Keyless Enter-N-Go
key fob is in the passenger compartment.
Normal Starting
Using The ENGINE START/STOP Button
1. The transmission must be in PARK or
NEUTRAL.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP button
once.
3. The system takes over and attempts to start the vehicle. If the vehicle fails to
start, the starter will disengage automati-
cally after 25 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, re-
move your foot from the brake pedal and
push the button again.
NOTE:
• Normal starting of either a cold or a warm engine is obtained without pumping or
pressing the accelerator pedal.
• Under cold weather conditions, the engine may not immediately crank if the "Wait To
Start" telltale is illuminated. This is normal
operation. For vehicles equipped with Key-
less Enter-N-Go, the vehicle will automati-

cally crank when the "Wait To Start" time
has elapsed. See the section "Starting Pro-
cedure Engine Manifold Air Temperature
0°F to 66°F (18° C to 19°C)" in the Diesel
Supplement for more information.
To Turn Off The Engine Using ENGINE START/
STOP Button
1. Place the gear selector in PARK, then push and release the ENGINE START/
STOP button.
2. The ignition will return to the OFF mode.
3. If the gear selector is not in PARK and the ENGINE START/STOP button is pushed
once, the instrument cluster will display a
“Vehicle Not In Park” message and the
engine will remain running. Never leave a
vehicle out of the PARK position, or it
could roll.
4. If the gear selector is in NEUTRAL, and the vehicle speed below 5 mph (8 km/h),
pushing the START/STOP button once will
turn the engine off. The ignition will re-
main in the ACC mode.
5.
If the vehicle speed is above 5 mph (8 km/h),
the ENGINE START/STOP button must be held for two seconds (or three short pushes
in a row) to turn the engine off. The ignition
will remain in the ACC mode (NOT the OFF
mode) if the engine is turned off when the
transmission is not in PARK.
NOTE:
If the ignition is left in the ACC or ON/RUN
(engine not running) mode and the transmis-
sion is in PARK, the system will automatically
time out after 30 minutes of inactivity and
the ignition return to the OFF mode.
ENGINE START/STOP Button Functions — With
Driver’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates
similar to an ignition switch. It has three
positions, OFF, ACC, RUN. To change the
ignition switch positions without starting the
vehicle and use the accessories follow these
steps:
1. Starting with the ignition in the OFF
position:
2. Push the ENGINE START/STOP button once to change the ignition to the ACC
position. 3. Push the ENGINE START/STOP button a
second time to change the ignition to the
RUN position.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF
position.
Keyless Enter-N-Go Starting Procedure —
Engine Manifold Air Temperature 0° F To
66° F (–18° C to 19° C)
NOTE:
The temperature displayed in the instrument
cluster does not necessarily reflect the en-
gine manifold air temperature. Refer to “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further in-
formation. When engine temperatures fall
below 66°F (19°C) the “Wait To Start Light”
will remain on indicating the intake manifold
heater system is active.
Follow the steps in the “Normal Starting”
procedure except:
1. Pushing the engine start button with thedriver’s foot on the brake will move the
147

ignition from OFF or ACC to RUN, and will
illuminate the "Wait To Start" telltale. The
engine will not immediately crank, this is
normal operation.
2. The “Wait To Start" telltale will remain on for a period of time that varies depending
on the engine temperature.
3. While the "Wait to Start" telltale is on, the instrument cluster will additionally dis-
play a gauge or bar whose initial length
represents the full "Wait to Start" time
period. Its length will decrease until it
disappears when the "Wait to Start" time
has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filters to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Dealer
Service” under “Servicing And Mainte-
nance” for further information. 4. After the engine “Wait To Start” telltale
goes off, the engine will automatically
crank.
CAUTION!
Do not crank engine for more than 15 sec-
onds at a time or starter motor damage
may result. Turn the ignition switch to the
OFF position and wait at least two minutes
for the starter to cool before repeating start
procedure.
5. After engine start-up, check to see that there is oil pressure.
6. Allow the engine to idle about three min- utes until the manifold heaters have com-
pleted the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically in- crease to 1,000 RPM and engage the Vari-
able Geometry Turbocharger at low coolant
temperatures to improve engine warm-up. • The engine may not automatically crank
after the engine "Wait To Start" telltale goes
off if a door or the hood is ajar.
• If the engine stalls, or if the ignition switch is left ON for more than two minutes after
the “Wait To Start Light” goes out, reset the
grid heaters by turning the ignition switch
to the OFF position for at least five seconds
and then back ON. Repeat steps 1 through
7 of “Keyless Enter-N-Go Starting Proce-
dure – Engine Manifold Air Temperature
Below 66° F (19° C).”
Extreme Cold Weather
The Cummins diesel engine is equipped with
several features designed to assist cold
weather starting and operation:
• The engine block heater is a resistance
heater installed in the water jacket of the
engine just above and behind the oil filter.
It requires a 110–115 Volt AC electrical
outlet with a grounded, three-wire exten-
sion cord.STARTING AND OPERATING

AUTOMATIC TRANSMISSION
WARNING!
• It is dangerous to shift out of PARK orNEUTRAL 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
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-
WARNING!
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 ap-
ply the parking brake fully when exiting
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.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
WARNING!
brake, brake pedal or the transmission
gear selector.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to
children), and do not leave the ignition
(in a vehicle equipped with Keyless
Enter-N-Go) in the ACC or ON/RUN
mode. A child could operate power win-
dows, other controls, or move the ve-
hicle.
CAUTION!
Damage to the transmission may occur if
the following precautions are not ob-
served:
• Shift into or out of PARK or REVERSEonly after the vehicle has come to a
complete stop.
• Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
• Before shifting into any gear, make sure
your foot is firmly pressing the brake
pedal.

control. Pressing the GEAR-/GEAR+ switches
(on the steering wheel) while in the DRIVE
position will select the highest available
transmission gear, and will display that gear
limit in the instrument cluster as 1, 2, 3, etc.
Refer to “Electronic Range Select (ERS) Op-
eration” 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
damage, Transmission Limp Home Mode is
activated. In this mode, the transmission may
operate only in certain gears, or may not shift
at all. Vehicle performance may be severely
degraded and the engine may stall. In some
situations, the transmission may not re-
engage if the engine is turned off and re-
started. The Malfunction Indicator Light
(MIL) may be illuminated. A message in the
instrument cluster will inform the driver of
the more serious conditions, and indicate
what actions may be necessary.
In the event of a momentary problem, the
transmission can be reset to regain all for-
ward gears by performing the following steps:
NOTE:
In cases where the instrument cluster mes-
sage indicates the transmission may not re-
engage after engine shutdown, perform this
procedure only in a desired location (prefer-
ably, at your authorized dealer).1. Stop the vehicle.
2. Shift the transmission into PARK, if pos-
sible. If not, shift the transmission to
NEUTRAL.
3. Turn the ignition to the OFF position. On vehicles with Keyless Enter-N-Go, push
and hold the ignition switch until the
engine turns OFF.
4. Wait approximately 30 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.
If the transmission cannot be reset, autho-
rized dealer service is required.
Electronic Transmission Gear Selector
157

The NEUTRAL (N) indicator light will
blink while the shift is in progress. The
light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is com-
plete. After the shift is completed and
the NEUTRAL (N) light stays on, re-
lease the NEUTRAL (N) button.
6. Release the parking brake.
7. Shift the transmission into REVERSE.
8. Release the brake pedal (and clutch pedal on manual transmissions) for five seconds
and ensure that there is no vehicle
movement.
9. Repeat steps 7 and 8 with automatic transmission in DRIVE or manual trans-
mission in first gear.
10. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn OFF
the engine. For vehicles with Keyless
Enter-N-Go, push and hold the ENGINE
START/STOP button until the engine
shuts off.
11. Shift the transmission into PARK or place manual transmission in gear (NOT in Neutral). On 8-speed transmissions
the shifter will automatically select
PARK when the engine is turned off.
12. Turn the ignition to the OFF mode, then cycle the ignition to the RUN mode and
back to the OFF mode. Remove the key
fob from the ignition.
13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the parking brake.
NOTE:
With electronic shift transfer case:
• Steps 2 through 4 are requirements that must be met before pushing the NEUTRAL
(N) button, and must continue to be met
until the shift has been completed. If any of
these requirements are not met before
pushing the NEUTRAL (N) button or are no
longer met during the shift, the NEUTRAL
(N) indicator light will flash continuously
until all requirements are met or until the
NEUTRAL (N) button is released. • The ignition must be in the ON/RUN mode
for a shift to take place and for the position
indicator lights to be operable. If the igni-
tion is not in the ON/RUN mode, the shift
will not take place and no position indicator
lights will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indicates that shift requirements have
not been met.
• If the vehicle is equipped with air suspen- sion, the engine should be started and left
running for a minimum of 60 seconds (with
all the doors closed) at least once every
24 hours. This process allows the air sus-
pension to adjust the vehicle’s ride height
to compensate for temperature effects.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your
vehicle for normal usage:
1. Bring the vehicle to a complete stop, leav-
ing it connected to the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
