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 189.
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 vehicle best, have factory-trained technicians, genuine Mopar® parts, and care about your satisfaction.

Manual Open/Close
To open the sunroof, push and hold the switch rearward to
full open.
To close the sunroof, push and hold the switch in the
forward position.
Any release of the switch during open or close operation
will stop the sunroof movement. The sunroof will remain in
a partially opened position until the switch is operated and
held again.
NOTE:If the sunshade is in the closed position when Express or
Manual Open operation is initiated the sunshade will auto -
matically open to the half open position prior to the
sunroof opening.
Opening And Closing The Power Sunshade
The sunshade has two programmed positions: half open
and full open positions. When operating the sunshade
from the closed position, the sunshade will always stop at
the half open position regardless of express or manual
open operation. The switch must be actuated again to
continue on to full open position.
If the sunroof is open or vented, the sunshade cannot be
closed beyond the half open position. Pushing the
sunshade close switch when the sunroof is open/vented
and the sunshade is at half open position will first
automatically close the sunroof prior to the sunshade
closing. Express Open/Close
Push the sunshade switch rearward and release it within
one-half second, the sunshade will open to the half open
position and stop automatically. Push and release the
switch again from the half open position and the
sunshade will open to the full open position and stop
automatically.
Push the sunshade switch forward and release it within
one-half second and the sunshade will close
automatically.
During Express Open or Express Close operation, any
other actuation of the sunroof switches will stop the
sunshade in a partially open position.
Manual Open/Close
Push and hold the sunshade switch rearward, the
sunshade will open to the half open position and stop
automatically. Push and hold the sunshade switch again
and the sunshade will open to the full open position.
Push and hold the switch forward and the sunshade will
close and stop at full closed position.
Releasing the switch while the sunshade is in motion will
stop the sunshade in a partially open position.
Pinch Protect Feature
This feature will detect an obstruction in the opening of
the sunroof during Express Close operation. If an
obstruction in the path of the sunroof is detected, the
sunroof will automatically retract. Remove the obstruction
if this occurs.
NOTE:If three consecutive sunroof close attempts result in Pinch
Protect reversals, Pinch Protect will disable and the
sunroof must be closed in Manual Mode.
Venting Sunroof
Push and release the Vent button within one half second
and the sunroof will open to the vent position. This is
called “Express Vent” and it will occur regardless of
sunroof position. During Express Vent operation, any
movement of the switch will stop the sunroof.
NOTE:If the sunshade was not already open, it will automatically
open prior to the roof opening to the vent position.
Ignition Off Operation
The power sunroof switch will remain active for up to
approximately 10 minutes after the ignition switch is
placed in the OFF position. Opening either front door will
cancel this feature.
NOTE:Ignition Off timing is programmable through the Uconnect
system Úpage 191.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean
the glass panel. Periodically check for and clear out any
debris that may have collected in the tracks.

conditions are met, the gauge and numeric display
will update to show 100%. If conditions are not met a
pop-up message of “To reset oil life engine must be
off with ignition in run” will be displayed (for five
seconds), and the user will remain at the Oil Life
screen.
5. Push and release the up or down arrow button
to exit the submenu screen.
NOTE:If the indicator message illuminates when you start the
vehicle, the oil change indicator system did not reset. If
necessary, repeat this procedure.
DISPLAY MENU ITEMS
Push and release the up or down arrow button until
the desired selectable menu icon is highlighted in the
instrument cluster display.
Speedometer

LaneSense systems.
Push and release the up or down arrow button
until the Driver Assist menu is displayed in the instrument
cluster display. Adaptive Cruise Control (ACC) Feature
The instrument cluster display displays the current ACC
system settings. The information displayed depends on
ACC system status.
Push the ACC on/off button (located on the steering
wheel) until one of the following displays in the instrument
cluster display:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adaptive
Cruise Control Off.”
Adaptive Cruise Control Ready
When ACC is activated but the vehicle speed setting has
not been selected, the display will read “Adaptive Cruise
Control Ready.”
Push the SET + or the SET- button (located on the steering
wheel) and the following will display in the instrument
cluster display:
ACC SET
When ACC is set, the set speed will display in the
instrument cluster

Rear Axle Locker Fault Warning Light —
If Equipped
This warning light will illuminate to indicate
when a rear axle locker fault has been
detected.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to indicate a
fault in the FCW System. Contact an authorized
dealer for service
Úpage 274.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning properly
and service is required. Contact an authorized
dealer for service.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal a fault
with the 4WD system. If the light stays on or
comes on during driving, it means that the 4WD
system is not functioning properly and that
service is required. We recommend you drive to the
nearest service center and have the vehicle serviced
immediately.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control System is not functioning
properly and service is required. Contact an
authorized dealer.
Tire Pressure Monitoring System (TPMS)
Warning Light
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 previously
mentioned, 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.
CAUTION!
Prolonged driving with the Malfunction Indicator Light
(MIL) on could cause damage to the vehicle control
system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
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.

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 illu -
minated until you place the ignition in the off posi -
tion 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 approved 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.
