Recreational Towing — Two-Wheel Drive
Models
DO NOT flat tow this vehicle. Damage to the
drivetrain will result.
Recreational towing (for two-wheel drive
models) is allowed ONLY if the rear wheels are
OFF the ground. This may be accomplished
using a tow dolly or vehicle trailer. If using a tow
dolly, follow this procedure:

1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer's instruc -
tions.

2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place auto -
matic transmission in PARK.
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer's instruc -
tions.
5. Turn the ignition to the OFF position and remove the key fob.
6. Install a suitable clamping device, designed for towing, to secure the front wheels in the
straight position.
Recreational Towing — Four-Wheel Drive
Models
NOTE:
Both the manual shift and electronic shift
transfer cases must be shifted into N (Neutral)
for recreational towing. Automatic transmis -
sions must be shifted into PARK for recreational
towing. Refer to the following for the proper
transfer case N (Neutral) shifting procedure for
your vehicle.
CAUTION!
Towing with the rear wheels on the ground
will cause severe transmission damage.
Damage from improper towing is not
covered under the New Vehicle Limited
Warranty.
Do not disconnect the driveshaft because
fluid may leak from the transmission,
causing damage to internal parts.
CAUTION!
DO NOT dolly tow any 4WD vehicle. Towing
with only one set of wheels on the ground
(front or rear) will cause severe transmis -
sion and/or transfer case damage. Tow
with all four wheels either ON the ground, or
OFF the ground (using a vehicle trailer).
Tow only in the forward direction. Towing
this vehicle backwards can cause severe
damage to the transfer case.
Before recreational towing, the transfer
case must be in NEUTRAL. To be certain the
transfer case is fully in NEUTRAL, perform
the procedure outlined under “Shifting Into
NEUTRAL”. Internal transmission damage
will result, if the transfer case is not in
NEUTRAL during towing.
The transmission must be placed in PARK
for recreational towing.
Towing this vehicle in violation of the above
requirements can cause severe transmis -
sion and/or transfer case damage.
Damage from improper towing is not
covered under the New Vehicle Limited
Warranty.

290STARTING AND OPERATING
Shifting Into N (Neutral)
Use the following procedure to prepare your
vehicle for recreational towing.
1. Bring the vehicle to a complete stop on
level ground, with the engine running.
Firmly apply the parking brake.

2. Shift the transmission to NEUTRAL.
3. Press and hold the brake pedal.
4. Shift the transfer case into N (Neutral):
With manual shift transfer case, shift the transfer case lever into N (Neutral).
With electronic shift transfer case, push and hold the transfer case N (Neutral)
button. Some models have a small,
recessed "N" button (at the center of the
transfer case switches) that must be
pressed using a ballpoint pen or similar
object. Other models have a rectangular
N (Neutral) switch, below the rotary
transfer case control knob. The N
(Neutral) indicator light will blink while
the shift is in progress. The light will stop blinking (stay on solid) when the shift to N
(Neutral) is complete. After the shift is
completed and the N (Neutral) light stays
on, release the N (Neutral) button.
5. Release the parking brake.
6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds and ensure that there is no vehicle move-
ment.
8. Repeat steps six and seven with automatic transmission in DRIVE.
9. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn off the engine.
For vehicles with Keyless Enter-N-Go, push
and hold the ENGINE START/STOP button
until the engine shuts off.
10. Shift the transmission into PARK.
11. Place the ignition in the OFF mode, and remove the key fob.
12. Attach the vehicle to the tow vehicle using a suitable tow bar.
13. Release the parking brake.
Do not disconnect the rear driveshaft
because fluid will leak from the transfer
case, causing damage to internal parts.
Do not use a bumper-mounted clamp-on
tow bar on your vehicle. The bumper face
bar will be damaged.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the NEUTRAL (N) position without first
fully engaging the parking brake. The transfer
case NEUTRAL (N) position disengages both
the front and rear driveshafts from the
powertrain, and will allow the vehicle to roll,
even if the automatic transmission is in PARK
(or manual transmission is in gear). The
parking brake should always be applied when
the driver is not in the vehicle.
CAUTION! (Continued)CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to
prevent damage to internal parts.

STARTING AND OPERATING291
NOTE:
With electronic shift transfer case:
Steps 2 through 3 are requirements that
must be met before pushing the N (Neutral)
button, and must continue to be met until the
shift has been completed. If any of these
requirements are not met before pushing the
N (Neutral) button or are no longer met
during the shift, the N (Neutral) indicator light
will flash continuously until all requirements
are met or until the N (Neutral) button is
released.
The ignition must be in the ON/RUN mode for
a shift to take place and for the position indi -
cator lights to be operable. If the ignition is
not in the ON/RUN mode, the shift will not
take place and no position indicator lights will
be on or flashing.
A flashing N (Neutral) position indicator light
indicates that shift requirements have not
been met.
Shifting Out Of N (Neutral)
Use the following procedure to prepare your
vehicle for normal usage:

1. Bring the vehicle to a complete stop,
leaving it connected to the tow vehicle.

2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine, and shift the transmission into NEUTRAL.
With manual shift transfer case, shift the transfer case lever to the desired posi -
tion.
With electronic shift transfer case with rotary selector switch, push and hold the
transfer case N (Neutral) button until the
N (Neutral) indicator light turns off. After
the N (Neutral) indicator light turns off,
release the N (Neutral) button. After the
N (Neutral) button has been released, the
transfer case will shift to the position indi -
cated by the selector switch.
With electronic shift transfer case with push-button selector switch, push and
hold the switch for the desired transfer
case position, until the N (Neutral) indi -
cator light turns off and the desired posi -
tion indicator light turns on.
NOTE:
When shifting out of transfer case N (Neutral),
turning the engine off is not required, but may
be helpful to avoid gear clash. With 8-speed
automatic transmission, the engine must
remain running, since turning the engine off will
shift the transmission to PARK (and the trans -
mission must be in NEUTRAL for the transfer
case to shift out of NEUTRAL).
5. Turn the engine off. Shift automatic trans- mission into PARK. On 8-speed transmis -
sions the shifter will automatically select
PARK when the engine is turned off.
6. Release the brake pedal.
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.

are met or until the button is released.
The ignition must be in the ON/RUN mode for
a shift to take place and for the position indi -
cator lights to be operable. If the ignition is
not in the ON/RUN mode, the shift will not
take place and no position indicator lights will
be on or flashing.
A flashing N (Neutral) position indicator light
indicates that shift requirements have not
been met.
DRIVING TIPS
Driving On Slippery Surfaces
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 rear (driving)
wheels.
Driving Through Water
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle.
Flowing/Rising Water
WARNING!
Rapid acceleration on slippery surfaces is
dangerous. Unequal traction can cause
sudden pulling of the rear wheels. You could
lose control of the vehicle and possibly have a
collision. Accelerate slowly and carefully
whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).
WARNING!
Do not drive on or across a road or path
where water is flowing and/or rising (as in
storm run-off). Flowing water can wear away
the road or path's surface and cause your
vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to
follow this warning may result in injuries that
are serious or fatal to you, your passengers,
and others around you.

IN CASE OF EMERGENCY297
SOS Call System Limitations
Vehicles sold in Mexico DO NOT have SOS Call
system capabilities.
SOS or other emergency line operators in
Mexico may not answer or respond to SOS
system calls.
If the SOS Call system detects a malfunction,
any of the following may occur at the time the
malfunction is detected, and at the beginning of
each ignition cycle:
The overhead console light located between
the ASSIST and SOS buttons will continuously
be illuminated red.
The Device Screen will display the following
message: “Vehicle device requires service.
Please contact an authorized dealer.”
An In-Vehicle Audio message will state
“Vehicle device requires service. Please
contact an authorized dealer.” Even if the SOS Call system is fully functional,
factors beyond FCA US LLC’s control may
prevent or stop the SOS Call system operation.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add
aftermarket electrical equipment to the
vehicle’s electrical system. This may
prevent your vehicle from sending a signal
to initiate an emergency call. To avoid inter
-
ference that can cause the SOS Call system
to fail, never add aftermarket equipment
(e.g., two-way mobile radio, CB radio, data
recorder, etc.) to your vehicle’s electrical
system or modify the antennas on your
vehicle. IF YOUR VEHICLE LOSES BATTERY
POWER FOR ANY REASON (INCLUDING
DURING OR AFTER AN ACCIDENT), THE
UCONNECT FEATURES, APPS AND
SERVICES, AMONG OTHERS, WILL NOT
OPERATE.
Modifications to any part of the SOS Call
system could cause the air bag system to
fail when you need it. You could be injured
if the air bag system is not there to help
protect you.
WARNING! (Continued)WARNING!
Ignoring the overhead console light could
mean you will not have SOS Call services. If
the overhead console light is illuminated,
have an authorized dealer service the SOS
Call system immediately.
The Occupant Restraint Control module
turns on the air bag Warning Light on the
instrument panel if a malfunction in any
part of the system is detected. If the Air Bag
Warning Light is illuminated, have an
authorized dealer service the Occupant
Restraint Control system immediately.
