INTRODUCTION
Dear Customer,
Congratulations on the purchase of your new Ram. Be assured that it represents precision workmanship, distinctive styling, and high quality.
This is a specialized utility vehicle. It can go places and perform tasks that are not intended for conventional passenger vehicles. 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 Úpage 188.
This Owner's Manual has been prepared with the assistance of service and engineering specialists to acquaint you with the operation and maintenance of your
vehicle. It is supplemented by customer-oriented documents. Within this information, you will find a description of the services that FCA US LLC offers to its
customers as well as 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 warnings in this manual will help ensure safe and
enjoyable operation of your vehicle.
This Owner’s Manual describes all versions of this vehicle. Options and equipment dedicated to specific markets or versions are not expressly indicated in the
text. Therefore, you should only consider the information that is related to the trim level, engine, and version that you have purchased. Any content introduced
throughout the Owner’s Information, which may or may not be applicable to your vehicle, will be identified with the wording “If Equipped”. All data contained in
this publication are intended to help you use your vehicle in the best possible way. FCA US LLC aims at a constant improvement of the vehicles produced. For

an authorized dealer to have the PIN reset.
DIESEL MESSAGES AND WARNINGS
Diesel Particulate Filter (DPF) Messages
The Cummins® diesel engine meets all diesel
emissions standards, resulting in one of the lowest
emitting diesel engines ever produced. To achieve
these emissions standards, your vehicle is
equipped with a state-of-the-art engine and
exhaust system. These systems are seamlessly
integrated into your vehicle and managed by the
Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust
system’s catalyst to trap and burn Particulate
Matter (PM) pollutants, with no input or interaction
on your part.
Your vehicle has the ability to alert you to
additional maintenance required on your vehicle or
engine. The following messages may display in
your instrument cluster display:
Perform Service — Your vehicle will require emis -
sions maintenance at a set interval. To help
remind you when this maintenance is due, the
instrument cluster display will display “Perform
Service”. When the “Perform Service” message
is displayed in the instrument cluster display it is
necessary to have the emissions maintenance
performed. Emissions maintenance may
include replacing the Closed Crankcase Ventila -
tion (CCV) filter element. The procedure for
clearing and resetting the "Perform Service"
indicator message is located in the appropriate
Service Information.
Exhaust System — Regeneration Required
Now — "Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy" will be displayed in
the instrument cluster display if the exhaust
particulate filter reaches 80% of its maximum
storage capacity. Under conditions of exclusive
short duration and low speed driving cycles,
your Cummins® diesel engine and exhaust
after-treatment system may never reach the
conditions required to remove the trapped PM.
If this occurs, the “Exhaust Filter XX% Full Safely
Drive at Highway Speeds to Remedy” message
will be displayed in the instrument cluster
display. If this message is displayed, you will
hear one chime to assist in alerting you of this
condition
WARNING!
A hot exhaust system can start a fire if you park
over materials that can burn. Such materials
might be grass or leaves coming into contact
with your exhaust system. Do not park or
operate your vehicle in areas where your
exhaust system can contact anything that can
burn.

Low Fuel Warning Light
When the fuel level reaches
approximately 3.2 gal (12 L) this light will
turn on, and remain on until fuel is
added.
A single warning chime will sound with Low Fuel
Warning.
Low Coolant Level Warning Light
This telltale will turn on to indicate the
vehicle coolant level is low Ú page 341.
Loose Fuel Filler Cap Warning Light —
If Equipped
This warning light will illuminate when the
fuel filler cap is loose. Properly close the
filler cap to disengage the light. If the
light does not turn off, please see an
authorized dealer.
Tire Pressure Monitoring System (TPMS)
Warning Light — If Equipped
The warning light switches on and a
message is displayed to indicate that the
tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire duration and fuel consumption may not be
guaranteed. Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a
significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. If a
tire puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.

104GETTING TO KNOW YOUR INSTRUMENT PANEL
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to
pass an inspection of your vehicle's emissions
control system. Failure to pass could prevent
vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies
the Malfunction Indicator Light (MIL) is
functioning and is not on when the
engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The
OBD II system may not be ready if your vehicle was
recently serviced, recently had a depleted battery
or a battery replacement. If the OBD II system
should be determined not ready for the I/M test,
your vehicle may fail the test.
Your vehicle has a simple ignition actuated test,
which you can use prior to going to the test station.
To check if your vehicle's OBD II system is ready,
you must do the following:
1. Cycle the ignition switch to the ON position,
but do not crank or start the engine.

NOTE:If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the Malfunction
Indicator Light (MIL) symbol come on as part of
a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
The MIL will flash for about 10 seconds and
then return to being fully illuminated until
you turn OFF the ignition or start the engine.
This means that your vehicle's OBD II
system is not ready and you should not
proceed to the I/M station.
The MIL will not flash at all and will remain
fully illuminated until you place the ignition
in the off position or start the engine. This
means that your vehicle's OBD II system is
ready and you can proceed to the I/M
station. If your OBD II system is
not ready, you should see
an authorized dealer or repair facility. If your
vehicle was recently serviced or had a battery
failure or replacement, you may need to do nothing
more than drive your vehicle as you normally would
in order for your OBD II system to update. A
recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system
is ready or not, if the MIL is illuminated during
normal vehicle operation you should have your
vehicle serviced before going to the I/M station.
The I/M station can fail your vehicle because the
MIL is on with the engine running.
