INTRODUCTION
Dear Customer, congratulations on the purchase of your new Ram 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, 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 234.
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 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 authorized dealers know your Ram best, have factory-trained technicians and genuine MOPAR® parts, and
care about your satisfaction.

GETTING TO KNOW YOUR VEHICLE
KEYS
KEY FOB
Your vehicle is equipped with a key fob which
supports Passive Entry, Remote Keyless Entry
(RKE), Keyless Enter-N-Go (if equipped), and
Remote Start (if equipped). The key fob allows
you to lock or unlock all doors, tailgate, and the
RamBox (if equipped) as well as activate the
Panic Alarm from distances up to approximately
66 ft (20 m). The key fob does not need to be
pointed at the vehicle to activate the system. The
key fob also contains an emergency key, which is
stored in the rear of the key fob.
NOTE:
The key fob’s wireless signal may be blocked if
the key fob is located next to a mobile phone,
laptop, or other electronic device. This may
result in poor performance.
If your vehicle is equipped with a Wireless
Charging Pad, the key fob may not be found if
it is placed within 15 cm (150 mm) of the pad
Ú page 77.
With the ignition in the ON position and the
vehicle moving at 2 mph (4 km/h), all RKE
commands are disabled.
Key Fob
In case the ignition switch does not change with
the push of a button, the key fob may have a low
or fully depleted battery. A low key fob battery
can be verified by referring to the instrument
cluster, which will display directions to follow.
NOTE:
A low key fob battery condition may be indicated
by a message in the instrument cluster display,
or by the LED light on the key fob. If the LED key
fob light no longer illuminates from key fob
button pushes, then the key fob battery requires
replacement.

To Lock/Unlock The Doors And Tailgate
Push and release the unlock button on the key
fob once to unlock the driver’s door, or, twice
within five seconds to unlock all doors, the
tailgate and the RamBox (if equipped). To lock all
the doors and the tailgate, push the lock button
once.
When the doors are unlocked, the turn signals
will flash and the illuminated entry system will
be activated. When the doors are locked, the
turn signals will flash and the horn will chirp.
All doors can be programmed to unlock on the
first push of the unlock button. The horn chirp

Úpage 237.
Air Suspension (Remote Lowering Of The
Vehicle) — If Equipped
For easy entry and loading, your
vehicle can be lowered by pushing the
key fob air suspension lowering button
two times. When air suspension
lowering is requested using the key fob, the
vehicle will send a series of chirps and flashes to
alert the customer that the operation has begun
and will continue these alerts until it successfully
lowers. The following conditions must be met for the
vehicle to lower remotely:
The vehicle must not already be in Entry/Exit
(Park) ride height.
The vehicle battery must be fully charged.
All doors must be closed.
The key fob must be out of the vehicle.
NOTE:
Ensure the vehicle is clear of all objects, pets,
and people prior to remote lowering.
Canceling Remote Lowering
Vehicle lowering can be cancelled at anytime.
When vehicle lowering is cancelled, the vehicle
will raise up to the next defined level and lock
out the remote lowering feature until the
ignition has been cycled ON/OFF.
To cancel vehicle lowering, push the key fob air
suspension lowering button one time during the
lowering process. When vehicle lowering is
cancelled, the horn will chirp two times and the
turn signal lamps will flash four times. Once
raising is completed, the horn will chirp one
time. NOTE:
More information on air suspension is provided
later in this manual Ú
page 165.
Replacing The Battery In The Key Fob
The replacement battery model is one CR2450
battery.

Customers are recommended to use a
battery obtained from Mopar. Aftermarket
coin battery dimensions may not meet the
original OEM coin battery dimensions.
Perchlorate Material — special handling may
apply. See www.dtsc.ca.gov/hazard -
ouswaste/perchlorate for further informa -
tion.
Do not touch the battery terminals that are
on the back housing or the printed circuit
board.
Do not replace the coin battery if the LED on
the key fob above the top row buttons blinks
when a button is pressed. The coin battery
should last a minimum of three years with
normal vehicle usage.
