INTRODUCTION
Dear Customer,
Congratulations on the purchase of your new Wagoneer/Grand Wagoneer. Be assured that it represents precision workmanship, distinctive styling, and high quality.
The Wagoneer/Grand Wagoneer 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 on rugged terrain or use in other severe conditions suited for a four-wheel drive vehicle. Before you 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. Driving skills 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 193.
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 vehicle best, have factory-trained technicians, genuine Mopar® parts, and care about your satisfaction.

Oil Level
The 3.0L engine does not have a
traditional “dipstick” and there is no
need to manually check the oil level
Úpage 316.
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message will
display in the instrument cluster display for five seconds
after a single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate, dependent upon
your personal driving style and environmental conditions.
Unless reset, this message will continue to display each
time the ignition is placed in the ON/RUN position. To turn
off the message temporarily, push and release the OK or
arrow buttons. To reset the oil change indicator system
(after performing the scheduled maintenance), refer to
the following procedure.3

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 mentioned
previously, 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
Úpage 252.
Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a failure
with the tow hook. Contact an authorized
dealer for service.
YELLOW INDICATOR LIGHTS
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the 4WD Low mode. The front and rear
driveshafts are mechanically locked together
forcing the front and rear wheels to rotate at
the same speed. Low range provides a greater gear
reduction ratio to provide increased torque at the wheels
Úpage 129.
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.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended that you
take your vehicle to an authorized dealer to have your
sensor function checked.
