2018 DODGE DURANGO SRT transfer case

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 pas-
senger 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 brak-
ing, 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. Refer to the “Driving Tips”
in “Starting and Operating” for further information.This Owner ’s Manual has been prepared with the assis-
tance 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. In the attached Warranty Booklet you
will find a description of the services that FCA 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
instructions, recommendations, tips, and important warn-
ings 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 Own-
er ’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 aims at
a constant improvement of the vehicles produced. For this
reason, it reserves the right to make changes to the model
4 INTRODUCTION

4. Allow vehicle to sit and cool in the paddock for at least30 min. If an infrared thermal gun is available, allow
rotors to cool to 200°F (93.3°C) before going back out.
5. There should be a thin ash layer when inspecting the pads installed in the caliper. Having the ash layer go
more than half the thickness of the pad material indi-
cates too aggressive of a burnish.
6. Sometimes, a second burnish session is required. If the pads start smelling in the next track session, reduce
speed and braking decel to burnish targets and follow
steps two through four.
7. New pads installed on old rotors still need to be burnished. New rotors installed with old pads should be
burnished at the track or street driven for 300 city miles
to develop an adequate lining transfer layer on the rotor
surface prior to track use.
8. Rotors that pulsate during track use should be replaced. Resurfacing of the rotors is not recommended, as it
removes mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor cheek, making
it less robust and increasing the likelihood of pulsation
in further track use.ALL-WHEEL DRIVE OPERATION
Single-Speed Operating Instructions/Precautions
This system contains a single-speed (HI range only) trans-
fer case, which provides convenient full-time all-wheel
drive. No driver interaction is required. The Brake Traction
Control (BTC) System, which combines standard ABS and
Traction Control, provides resistance to any wheel that is
slipping to allow additional torque transfer to wheels with
traction.
NOTE: This system is not appropriate for conditions
where LOW range is recommended. Refer to “Driving
Tips” in “Starting And Operating” for further information.
FUEL SAVER TECHNOLOGY 6.4L ONLY — IF
EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine’s eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE: This system may take some time to return to full
functionality after a battery disconnect.
280 STARTING AND OPERATING

WARNING!(Continued)
PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or
chockthe trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures. •
Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.
•
When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity will not
increase the vehicle’s GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).

STARTING AND OPERATING 343

Highway Driving
•Reduce speed.
• Temporarily turn off air conditioning.
RECREATIONAL TOWING
Recreational towing is not allowed.
CAUTION!
Towing this vehicle with any of its wheels on the
ground can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.
NOTE: This vehicle may be towed on a flatbed or vehicle
trailer provided all four wheels are OFFthe ground.
DRIVING TIPS
Driving On Slippery Surfaces
Information in this section will aid in safe controlled
launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the front (driving)
wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the front
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and care-
fully whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).

sion shifting occurring).
TOWING A DISABLED VEHICLE
The manufacturer requires towing your vehicle with all
four wheels OFFthe ground using a flatbed.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK
for loading onto a flatbed truck.
CAUTION!
• Towing this vehicle using any other method can
