2018 Ram 1500 stop start

4WD LOCK
Four-Wheel Drive Lock High Range — This
range maximizes torque to the front drive-
shaft, forcing the front and rear wheels to
rotate at the same speed. Additional traction
for loose, slippery road surfaces only.
4WD LOW
Four-Wheel Drive Low Range — This range
provides low speed four-wheel drive. It maxi-
mizes torque to the front driveshaft, forcing
the front and rear wheels to rotate at the same
speed. This range provides additional trac-
tion and maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NEUTRAL (N)
Neutral — This range disengages both the
front and rear driveshafts from the pow-
ertrain. To be used for flat towing behind
another vehicle. Refer to “Recreational Tow-
ing” in this section for further information.
This electronically shifted transfer case is
designed to be driven in the two–wheel drive
position (2WD) or four-wheel drive position
(4WD AUTO) for normal street and highwayconditions on dry hard surfaced roads). Driv-
ing the vehicle in 2WD will have greater fuel
economy benefits as the front axle is not
engaged in 2WD.
For variable driving conditions, the 4WD
AUTO mode can be used. In this mode, the
front axle is engaged, but the vehicle's power
is sent to the rear wheels. Four-wheel drive
will be automatically engaged when the ve-
hicle senses a loss of traction. Because the
front axle is engaged, this mode will result in
lower fuel economy than the 2WD mode.
When additional traction is required, the
transfer case 4WD LOCK and 4WD LOW po-
sitions can be used to maximize torque to the
front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This is
accomplished pushing the desired position
on the 4WD Control Switch.
Refer to “Shifting Procedure” in the “Start-
ing And Operating” section of your Owner’s
Manual for further details.WARNING!
• You or others could be injured or killed if
you leave the vehicle unattended with
the transfer case in the NEUTRAL (N)
position without first fully engaging the
parking brake. The transfer case NEU-
TRAL (N) position disengages both the
front and rear drive shaft from the pow-
ertrain, and will allow the vehicle to roll,
even if the automatic transmission is in
PARK (or manual transmission is in
gear). The parking brake should always
be applied when the driver is not in the
vehicle.
• The transmission may not engage PARK
if the vehicle is moving. Always bring the
vehicle to a complete stop before shift-
ing to PARK, and verify that the trans-
mission gear position indicator solidly
indicates PARK (P) without blinking. En-
sure that the vehicle is completely
stopped, and the PARK position is prop-
erly indicated, before exiting the ve-
hicle.

The DEF injection system consists of the
following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst
The DEF injection system and SCR catalyst
enable the achievement of diesel emissions
requirements; while maintaining outstanding
fuel economy, drivability, torque and power
ratings.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
system messages and warnings.
NOTE:
• Your vehicle is equipped with a DEF injec-tion system. You may occasionally hear an
audible clicking noise from under the ve-
hicle at a stop. This is normal operation. • The DEF pump will run for a period of time
after engine shutdown to purge the DEF
system. This is normal operation and may
be audible from the rear of the vehicle.
Adding Diesel Exhaust Fluid
The DEF gauge (located on the instrument
cluster) will display the level of DEF remain-
ing in the tank. Refer to “Instrument Cluster”
and “Instrument Cluster Descriptions” in
“Getting To Know Your Instrument Panel” for
further information.
NOTE:
• Driving conditions (altitude, vehicle speed,load, etc.) will effect the amount of DEF
that is used in your vehicle.
• Another factor is that outside temperature can affect DEF consumption. In cold con-
ditions, 12° F (-11° C) and below, the DEF
gauge needle can stay on a fixed position
and may not move for extended periods of
time. This is a normal function of the sys-
tem. • There is an electric heater inside the DEF
tank that automatically works when neces-
sary. And if the DEF supply does freeze, the
truck will operate normally until it thaws.
DEF Fill Procedure
NOTE:
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for the correct fluid type.
1. Remove cap from DEF tank (located on
drivers side of the vehicle or in fuel door).
STARTING AND OPERATING
184

CAUTION!
• Never add anything other than DEF tothe tank – especially any form of hydro-
carbon such as diesel fuel, fuel system
additives, gasoline, or any other
petroleum-based product. Even a very
small amount of these, less than
100 parts per million or less than 1 oz.
per 78 gallons (295 liters) will contami-
nate the entire DEF system and will
require replacement. If owners use a
container, funnel or nozzle when refilling
the tank, it should either be new or one
that is has only been used for adding
DEF. Mopar provides an attachable
nozzle with its DEF for this purpose.
3. Stop filling the DEF tank immediately when any of the following happen: DEF
stops flowing from the fill bottle into the
DEF tank, DEF splashes out the filler
neck, or a DEF pump nozzle automatically
shuts off.
4. Reinstall cap onto DEF tank. Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F
(-11°C), your vehicle is equipped with an
automatic DEF heating system. This allows
the DEF injection system to operate properly
at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended
period of time with temperatures below 12°F
(-11°C), the DEF in the tank may freeze. If
the tank is overfilled and freezes, it could be
damaged. Therefore, do not overfill the DEF
tank.
Extra care should be taken when filling with
portable containers to avoid overfilling. Note
the level of the DEF gauge in your instrument
cluster. You may safely add a maximum of
2 gallons (7.5 Liters) of DEF from portable
containers when your DEF gauge is reading ½
full.
REFUELING THE VEHICLE —
2500/3500 DIESEL MODELS
1. Open the fuel filler door.
NOTE:
There is no fuel filler cap. A flapper door
inside the filler pipe seals the system.

CAUTION!
• DO NOT OVERFILL. DEF will freeze be-low 12ºF (-11ºC). The DEF system is
designed to work in temperatures below
the DEF freezing point, however, if the
tank is overfilled and freezes, the system
could be damaged.
• When DEF is spilled, clean the area immediately with water and use an ab-
sorbent material to soak up the spills on
the ground.
• Do not attempt to start your engine if DEF is accidentally added to the diesel
fuel tank as it can result in severe dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.
CAUTION!
• Never add anything other than DEF tothe tank – especially any form of hydro-
carbon such as diesel fuel, fuel system
additives, gasoline, or any other
petroleum-based product. Even a very
small amount of these, less than
100 parts per million or less than 1 oz.
per 78 gallons (295 liters) will contami-
nate the entire DEF system and will
require replacement. If owners use a
container, funnel or nozzle when refilling
the tank, it should either be new or one

WARNING!
•Total weight must be distributed between
the tow vehicle and the trailer such that the
following four ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
Towing Requirements — Trailer Brakes
•Do notinterconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause
inadequate braking and possible personal
injury.
• An electronically actuated trailer brake controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required. • Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
WARNING!
•Do not connect trailer brakes to your ve-
hicle's hydraulic brake lines. It can over-
load your brake system and cause it to
fail. You might not have brakes when you
need them and could have a collision.
• Towing any trailer will increase your stopping distance. When towing you
should allow for additional space be-
tween your vehicle and the vehicle in
front of you. Failure to do so could result
in a collision.
CAUTION!
If the trailer weighs more than 1,000 lbs
(453 kg) loaded, it should have its own
brakes and they should be of adequate
capacity. Failure to do this could lead to
accelerated brake lining wear, higher
brake pedal effort, and longer stopping
distances.
Integrated Trailer Brake Module — If
Equipped
Your vehicle may have an Integrated Trailer
Brake Module (ITBM) for Electric and Elec-
tric Over Hydraulic (EOH) trailer brakes.
NOTE:
This module has been designed and verified
with electric trailer brakes and new electric
over hydraulic systems. Some previous EOH
systems may not be compatible with ITBM.
STARTING AND OPERATING

CAUTION!
• Before recreational towing, the transfercase must be in NEUTRAL. To be certain
the transfer case is fully in NEUTRAL,
perform the procedure outlined under
“Shifting Into NEUTRAL”. Internal
transmission damage will result, if the
transfer case is not in NEUTRAL during
towing.
• Automatic transmissions must be
placed in PARK, and manual transmis-
sions must be placed in gear (not in
Neutral) for recreational towing.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case dam-
age. Damage from improper towing is
not covered under the New Vehicle Lim-
ited Warranty.
• Do not disconnect the rear driveshaft
because fluid will leak from the transfer
case, causing damage to internal parts.
• Do not use a bumper-mounted clamp-on
tow bar on your vehicle. The bumper
face bar will be damaged.
Shifting Into NEUTRAL (N)
Use the following procedure to prepare your
vehicle for recreational towing.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking
brake. The transfer case NEUTRAL (N)
position disengages both the front and rear
driveshafts from the powertrain, and will
allow the vehicle to roll, even if the auto-
matic transmission is in PARK (or manual
transmission is in gear). The parking brake
should always be applied when the driver
is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in
NEUTRAL (N) before recreational towing
to prevent damage to internal parts. 1. Bring the vehicle to a complete stop on
level ground, with the engine running.
Firmly apply the parking brake.
2. Shift the transmission to NEUTRAL.
NOTE:
If vehicle is equipped with air suspension,
ensure the vehicle is set to Normal Ride
Height.
3. Press and hold the brake pedal.
4. Depress the clutch pedal on a manual transmission.
5. Shift the transfer case into NEUTRAL:
• With manual shift transfer case, shiftthe transfer case lever into NEUTRAL
(N)
• With electronic shift transfer case, push and hold the transfer case NEU-
TRAL (N) button. Some models have a
small, recessed “N” button (at the cen-
ter of the transfer case switches) that
must be pushed using a ballpoint pen
or similar object. Other models have a
rectangular NEUTRAL switch, below
the rotary transfer case control knob.
STARTING AND OPERATING
198

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.
