INTRODUCTION
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 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, trans -
mission, 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 “Driving Tips” in “Starting and Oper
-
ating” for further information.
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 supple -
mented by Warranty Information, and customer oriented
documents located online. Within this information, you will
find a description of the services that FCA US LLC 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 instruc -
tions, 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.

Pinch Protect Feature
This feature will detect an obstruction in the closing of the
sunroof during the Express Close operation. If an obstruction
in the path of the sunroof is detected, the sunroof will auto-
matically 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 — Express
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 posi -
tion. During Express Vent operation, any other actuation of
the switch will stop the sunroof.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean the
glass panel. 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 time is programmable through the Uconnect
System. Refer to “Uconnect Settings” in “Multimedia” for
further information.
Relearn Procedure
For vehicles equipped with a sunroof, there is a relearn
procedure that allows you to calibrate the sunroof when the
“Express Operation” feature stops working. To reset the
sunroof, follow these steps:
1. Place the ignition in the ACC or the ON/RUN position.
2. Ensure that the sunroof is in the fully closed position.
3. Push and hold the close switch. The sunroof will hit the
hard stop and move to the vent position after ten seconds.
4. Release the close switch.
