INTRODUCTIONINTRODUCTION
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 the “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. 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, recom -
mendations, 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.
Any content introduced throughout the Owner’s Informa -
tion, that may or may not be applicable to your vehicle, will

166 SAFETY
6. Push the “ESC Off” button located in the lower switch
bank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an addi -
tional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the
sequence was completed properly, the “ESC Off Indicator
Light” will blink several times to confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to its
previous setting.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce engine
power to provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD), functions
similar to a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is spinning
faster than the other, the system will apply the brake of the
spinning wheel. This will allow more engine power to be
applied to the wheel that is not spinning. BLD may remain
enabled even if TCS and ESC are in a reduced mode. Electronic Stability Control (ESC)
This system enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in counteracting
the oversteer or understeer condition. Engine power may
also be reduced to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle path
intended by the driver and compares it to the actual path of
the vehicle. When the actual path does not match the
intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.
• Oversteer — when the vehicle is turning more than appro -
priate for the steering wheel position.
• Understeer — when the vehicle is turning less than appro -
priate for the steering wheel position.

STARTING AND OPERATING 257
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual downshifts
can be made using the Electronic Range Select (ERS) shift
control. Pushing the ERS (-/+) switches (on the steering
wheel) while in the DRIVE position will select the highest
available transmission gear, and will display that gear limit
in the instrument cluster as 1, 2, 3, etc. Refer to "Electronic
Range Select (ERS) Operation" in this section for further
information. Some models will display both the selected gear
limit, and the actual current gear, while in ERS mode.
Gear Ranges
Do not depress the accelerator pedal when shifting from
PARK or NEUTRAL into another gear range.
NOTE:
After selecting any gear range, wait a moment to allow the
selected gear to engage before accelerating. This is especially
important when the engine is cold. PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range. Never
attempt to use PARK while the vehicle is in motion. Apply
the parking brake when exiting the vehicle in this range.
When parking on a level surface, you may shift the transmis -
sion into PARK first, and then apply the parking brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of PARK. As an added precaution,
turn the front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade.
NOTE:
On four-wheel drive vehicles be sure that the transfer case is
in a drive position.
When exiting the vehicle, always:
• Apply the parking brake.
• Shift the transmission into PARK.
• Turn the engine OFF.
• Remove the key fob. 5

270 STARTING AND OPERATING
3. Push and hold the ignition switch until the engine turns
OFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE:
Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic equip -
ment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer service
is required.
Electronic Range Select (ERS) Operation — Eight-Speed
Transmission
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the transmis -
sion is in DRIVE. For example, if you set the transmission
gear limit to 4 (fourth gear), the transmission will not shift above fourth gear (except to prevent engine overspeed), but
will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission gear selector is in
DRIVE, the transmission will operate automatically, shifting
between all available gears. Tapping the GEAR- switch (on
the steering wheel) will activate ERS mode, display the
current gear in the instrument cluster, and set that gear as the
top available gear. Once in ERS mode, tapping the GEAR- or
GEAR+ switch will change the top available gear.
