2018 Ram 2500 suspension

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 ignition 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 indi-
cates that shift requirements have not been met.
• If the vehicle is equipped with air suspension, 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 suspension 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, leaving it con-
nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine. Shift the transmission into 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) indicator light turns off,
release the NEUTRAL (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.
440 STARTING AND OPERATING

After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts. •
After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.

CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
JACKING AND TIRE CHANGING
Jacking And Tire Changing 1500 Series Trucks
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 the danger of being hit when
operating the jack or changing the wheel.
(Continued)
WARNING! (Continued)
•Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
• Never start or run the engine while the vehicle is on
a jack.
• The jack is designed to be used as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or
slippery areas.
NOTE: If your vehicle is equipped with an air suspension
system, there is a feature which allows the automatic
leveling to be disabled to assist with changing a tire.
If your vehicle is equipped with a touchscreen, this feature
can be activated through the Uconnect system. Refer to
“Uconnect Settings” in “Multimedia” for further informa-
tion.
468 IN CASE OF EMERGENCY

WARNING!(Continued)
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
•Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL
for at least one minute after every five rocking-
motion cycles. This will minimize overheating and
reduce the risk of clutch or transmission failure
during prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shifting between
DRIVE/2nd gear and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
(Continued)
CAUTION! (Continued)
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the transmis-
sion and drivetrain are operable, disabled vehicles may
also be towed as described under “Recreational Towing” in
the “Starting And Operating” section.
NOTE: Vehicles equipped with air suspension must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to Air
Suspension inStarting And Operating for more informa-
tion. If the vehicle cannot be placed in Transport mode (for
example, engine will not run), tie-downs must be fastened
to the axles (not to the body). Failure to follow these
instructions may cause fault codes to be set and/or cause
loss of proper tie-down tension.
510 IN CASE OF EMERGENCY

CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheels OFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmission
is operable, the vehicle may be towed (with rear wheels on
the ground) under the following conditions:
• The transmission must be in NEUTRAL. Refer to
Manual Park Release in this section for instructions on
shifting the 8–speed transmission to NEUTRAL when
the engine is OFF.
• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 15 miles (24 km)
for 6–speed transmission, or 30 miles (48 km) for
8–speed transmission. If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than
15 miles (24 km) for 6–speed transmission, or 30 miles
(48 km) for 8–speed transmission, tow with the rear wheels
OFF
the ground. Acceptable methods are to tow the vehicle
on a flatbed, or with the front wheels raised and the rear
wheels on a towing dolly, or (when using a suitable
steering wheel stabilizer to hold the front wheels in the
straight position) with the rear wheels raised and the front
wheels on the ground.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe engine and/or transmission
damage. Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFF the ground. Acceptable methods are to tow the vehicle
on a flatbed or with one end of vehicle raised and the
opposite end on a towing dolly.
