INTRODUCTION
Dear Customer, congratulations on selecting
your new vehicle. 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, provin-cial 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” in
“Starting and Operating” for further informa
-
tion.
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 Warranty Information, and
customer-oriented documents. Within this
information, you will find a description of the
services that FCA US LLC offers to its
customers, the vehicle's warranty coverage,
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 warnings in this manual will help
assure 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 which is related to the
trim level, engine, and version that you have
purchased. Any content introduced throughout
the Owner's Information, that 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 this reason, it reserves
the right to make changes to the model
described for technical and/or commercial
reasons. For further information, contact an
authorized dealer.
When it comes to service, remember that an
authorized dealer knows your vehicle best, has
factory-trained technicians and genuine
MOPAR® parts, and cares about your
satisfaction.

REMOTE START — IF EQUIPPED (DIESEL)
This system uses the key fob to start
the engine conveniently from outside
the vehicle while still maintaining
security. The system has a range of
approximately 300 ft (91 m).
NOTE:
Obstructions between the vehicle and the
key fob may reduce this range.

2020_RAM_CHASSIS_CAB_OM_USA=GUID-6C67832B-7839-4CCF-BEFC-CDF988F949EA=1=en=.book Page 20

22GETTING TO KNOW YOUR VEHICLE
Additional features, such as windshield
wipers, will also not be available while the
vehicle is in the Remote Start mode.
The engine can be started two consecutive
times (two 15 minute cycles) with the key
fob. However, the ignition switch must be
placed in the ON/RUN position before you
can repeat the start sequence for a third
cycle.
To Exit Remote Start Mode Without Driving
The Vehicle
Push and release the Remote Start button one
time or allow the engine to run for the entire
15 minute cycle.
NOTE:
To avoid unintentional shut downs, the system
will disable for two seconds after receiving a
valid Remote Start request.
To Exit Remote Start Mode And Drive The
Vehicle
To exit Remote Start Mode and drive the vehicle
before the end of the 15 minute cycle, push and
release the unlock button on the key fob to
unlock the door and disarm the vehicle security alarm System (if equipped). Then, prior to the
end of the 15 minute cycle, place the ignition in
the ON/RUN position.
NOTE:
The ignition switch must be in the ON/RUN posi
-
tion in order to drive the vehicle.
Remote Start Comfort Systems — If
Equipped
When remote start is activated, the heated
steering wheel, and driver heated seat features
will automatically turn on in cold weather. In
warm weather, the driver vented seat feature
will automatically turn on when the remote start
is activated. These features will stay on through
the duration of remote start or until the ignition
switch is placed in the ON/RUN position.
NOTE:
The Remote Start Comfort System can be acti -
vated and deactivated through the Uconnect
System. Refer to “Uconnect Settings” in “Multi -
media” for further information on Remote Start
Comfort System operation.
SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed
or activated. Operation is automatic, regardless
of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. There -
fore, only key fobs that are programmed to the
vehicle can be used to start and operate the
vehicle. The system cannot reprogram a key fob
obtained from another vehicle.
After placing the ignition switch in the ON/RUN
position, the vehicle security light will turn on for
three seconds for a bulb check. If the light
remains on after the bulb check, it indicates
that there is a problem with the electronics. In
addition, if the light begins to flash after the
bulb check, it indicates that someone
attempted to start the engine with an invalid key
fob. In the event that a valid key fob is used to
start the engine but there is an issue with the
vehicle electronics, the engine will start and
shut off after two seconds.
