2018 Ram 2500 parking brake

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.

Towing Requirements
To promote proper break-in of your new ve-
hicle drivetrain components, the following
guidelines are recommended.
CAUTION!
• Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts
could be damaged.
CAUTION!
• Then, during the first 500 miles(805 km) that a trailer is towed, do not
drive over 50 mph (80 km/h) and do not
make starts at full throttle. This helps
the engine and other parts of the vehicle
wear in at the heavier loads.
Perform the maintenance listed in the
“Scheduled Servicing”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance”
for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or
GCWR ratings.
WARNING!
Improper towing can lead to a collision.
Follow these guidelines to make your
trailer towing as safe as possible:
• Make certain that the load is secured in the trailer and will not shift during travel.
When trailering cargo that is not fully
secured, dynamic load shifts can occur
that may be difficult for the driver to
WARNING!
control. You could lose control of your
vehicle and have a collision.
• When hauling cargo or towing a trailer,
do not overload your vehicle or trailer.
Overloading can cause a loss of control,
poor performance or damage to brakes,
axle, engine, transmission, steering,
suspension, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always
connect the chains to the hook retainers
of the vehicle hitch. Cross the chains
under the trailer tongue and allow
enough slack for turning corners.
• Vehicles with trailers should not be
parked on a grade. When parking, apply
the parking brake on the tow vehicle. Put
the tow vehicle transmission in PARK.
For four-wheel drive vehicles, make sure
the transfer case is not in NEUTRAL.
Always, block or "chock" the trailer
wheels.
• GCWR must not be exceeded.

Recreational Towing —
Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the
drivetrain will result.
Recreational towing (for two-wheel drive
models) is allowedONLYif the rear wheels are
OFF the ground. This may be accomplished
using a tow dolly or vehicle trailer. If using a
tow dolly, follow this procedure:
NOTE:
If vehicle is equipped with air suspension,
ensure the vehicle is set to Normal Ride
Height.
1. Properly secure the dolly to the tow ve- hicle, following the dolly manufacturer's
instructions.
2. Drive the rear wheels onto the tow dolly. 3. Firmly apply the parking brake. Place au-
tomatic transmission in PARK, manual
transmission in gear (not in NEUTRAL).
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer's
instructions.
5. Turn the ignition OFF and remove the key fob.
6. Install a suitable clamping device, de- signed for towing, to secure the front
wheels in the straight position.
CAUTION!
• Towing with the rear wheels on theground will cause severe transmission
damage. Damage from improper towing
is not covered under the New Vehicle
Limited Warranty.
• Do not disconnect the driveshaft be-
cause fluid may leak from the transmis-
sion, causing damage to internal parts.
Recreational Towing —
Four-Wheel Drive Models
NOTE:
Both the manual shift and electronic shift
transfer cases must be shifted into NEUTRAL
(N) for recreational towing. Automatic trans-
missions must be shifted into PARK for rec-
reational towing. Manual transmissions must
be placed in gear (NOT in NEUTRAL) for
recreational towing. Refer to the following for
the proper transfer case NEUTRAL (N) shift-
ing procedure for your vehicle.
CAUTION!
• DO NOT dolly tow any 4WD vehicle.Towing with only one set of wheels on the
ground (front or rear) will cause severe
transmission and/or transfer case dam-
age. Tow with all four wheels either ON
the ground, or OFF the ground (using a
vehicle trailer).
• Tow only in the forward direction. Towing
this vehicle backwards can cause severe
damage to the transfer case.
197

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.

4. Start the engine. Shift the transmissioninto NEUTRAL. Depress the clutch pedal
on a manual transmission.
• With manual shift transfer case, shift the transfer case lever to the desired
position.
• With electronic shift transfer case with rotary selector switch, push and hold
the transfer case NEUTRAL (N) button
until the NEUTRAL (N) indicator light
turns off. After the NEUTRAL (N) indi-
cator light turns off, release the NEU-
TRAL (N) button. After the NEUTRAL
(N) button has been released, the
transfer case will shift to the position
indicated by the selector switch.
• With electronic shift transfer case with push-button selector switch, push and
hold the switch for the desired transfer
case position, until the NEUTRAL (N)
indicator light turns off and the desired
position indicator light turns on. NOTE:
When shifting out of transfer case NEUTRAL
(N), turning the engine OFF is not required,
but may be helpful to avoid gear clash. With
the 8-speed automatic transmission, the en-
gine must remain running, since turning the
engine OFF will shift the transmission to
PARK (and the transmission must be in NEU-
TRAL for the transfer case to shift out of
NEUTRAL).
5. Turn the engine OFF. Shift automatic
transmission into PARK. On 8-speed
transmissions the shifter will automati-
cally select PARK when the engine is
turned off.
6. Release the brake pedal (and clutch pedal on a manual transmission).
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.
9. Press and hold the brake pedal.
10. Release the parking brake.
11. Shift the transmission into gear, release the brake pedal (and clutch pedal on
manual transmissions), and check that
the vehicle operates normally. NOTE:
With electronic shift transfer case:
• Steps 3 and 4 are requirements that must
be met before pushing the button to shift
out of NEUTRAL (N), and must continue to
be met until the shift has been completed.
If any of these requirements are not met
before pushing the 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 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.

NOTE:
Always stow the spare tire with the valve stem
facing the ground. It is recommended that
you stow the flat or spare to avoid tangling the
loose cable.NOTE:
The winch mechanism is designed for use
with the extension tube only. Use of an air
wrench or other power tools is not recom-
mended and can damage the winch.
Preparations For Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery areas.
WARNING!
Do not attempt to change a tire on the side
of the vehicle close to moving traffic, pull
far enough off the road to avoid being hit
when operating the jack or changing the
wheel.
2. Place the gear selector into PARK. On four-wheel drive vehicles, shift the trans-
fer case to the 4L position.
3. Turn on the Hazard Warning flasher.
4. Apply the parking brake.
5. Turn the ignition OFF. 6. Block both the front and rear of the wheel
diagonally opposite the jacking position.
For example, if the right front wheel is
being changed, block the left rear wheel.
