2018 Ram 2500 service manual

INTRODUCTION
Dear Customer, congratulations on selecting your new
vehicle. Be assured that it represents precision workman-
ship, distinctive styling, and high quality.
This is a specialized utility vehicle. It can go places and
perform tasks that conventional passenger vehicles are not
intended. It handles and maneuvers differently from many
passenger vehicles both on-road and off-road, so take time
to become familiar with your vehicle. If equipped, the
two-wheel drive version of this vehicle was designed for
on-road use only. It is not intended for off-road driving or
use in other severe conditions suited for a four-wheel drive
vehicle. Before you start to drive this vehicle, read the
Owner ’s Manual. Be sure you are familiar with all vehicle
controls, particularly those used for braking, steering,
transmission, and transfer case shifting. Learn how your
vehicle handles on different road surfaces. Your driving
skills will improve with experience. When driving off-road,
or working the vehicle, don’t overload the vehicle or expect
the vehicle to overcome the natural laws of physics.
Always observe federal, state, provincial and local laws
wherever you drive. As with other vehicles of this type,
failure to operate this vehicle correctly may result in loss of
control or a collision. Refer to the “Driving Tips” section for
further information.This Owner ’s Manual has been prepared with the assis-
tance of service and engineering specialists to acquaint you
with the operation and maintenance of your vehicle. It is
supplemented by Warranty Information, and customer
oriented documents. In the attached Warranty Booklet you
will find a description of the services that FCA offers to its
customers, the Warranty Certificate and the details of the
terms and conditions for maintaining its validity. Please
take the time to read all of these publications carefully
before driving your vehicle for the first time. Following the
instructions, recommendations, tips, and important warn-
ings in this manual will help assure safe and enjoyable
operation of your vehicle.

webbing necessary to comfortably wrap around the occu-
pant’s mid-section. Slide the latch plate into the buckle
until you hear aclick.
In Automatic Locking Mode, the shoulder belt is automati-
cally pre-locked. The seat belt will still retract to remove
any slack in the shoulder belt. Use the Automatic Locking
Mode anytime a child restraint is installed in a seating
position that has a seat belt with this feature. Children 12
years old and under should always be properly restrained
in a vehicle with a rear seat.
WARNING!
•Never place a rear-facing child restraint in front of an air
bag. A deploying passenger front air bag can cause
death or serious injury to a child 12 years or younger,
including a child in a rear-facing child restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grasp the shoulder portion and pull downward until the entire seat belt is extracted. 3. Allow the seat belt to retract. As the seat belt retracts,
you will hear a clicking sound. This indicates the seat
belt is now in the Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and allow it
to retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency) lock-
ing mode.
WARNING!
• The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the procedures
in the Service Manual.
• Failure to replace the seat belt assembly could in-
crease the risk of injury in collisions.
• Do not use the Automatic Locking Mode to restrain
occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is only
used to install rear-facing or forward-facing child
restraints that have a harness for restraining the
child.
236 SAFETY

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.
LIMITED-SLIP DIFFERENTIAL
The limited-slip differential provides additional traction on
snow, ice, mud, sand and gravel, particularly when there is
a difference between the traction characteristics of the
surface under the right and left rear wheels. During normal
