TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your bumper or trailer hitch.

Weight Distribution
Consider the following items when computing the
weight on the rear axle of the vehicle:The tongue weight of the trailer.
The weight of any other type of cargo or equip
-
ment put in or on your vehicle.
The weight of the driver and all passengers.
NOTE:
Remember that everything put into or on the trailer
adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options
must be considered as part of the total load on your
vehicle. Refer to the Tire And Loading Information
placard for the maximum combined weight of occu -
pants and cargo for your vehicle
Ú
page 230.

TOWING REQUIREMENTS
To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
Perform the maintenance listed in the Scheduled
Servicing Ú page 198. When towing a trailer,
never exceed the GAWR or GCWR ratings.
CAUTION!
Always load a trailer with 60% of the weight in
the front of the trailer. This places 10% of the
GTW on the tow hitch of your vehicle. Loads
balanced over the wheels or heavier in the rear
can cause the trailer to sway severely side to
side which will cause loss of control of the
vehicle and trailer. Failure to load trailers heavier
in front is the cause of many trailer collisions.
CAUTION!

Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine,
axle or other parts could be damaged.

Then, during the first 500 miles (805 km) that
a trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.4

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.

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.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú page 225.
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 personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated 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 lb (453 kg) and may be required for
any trailer, for example trailers in excess of
2,000 lb (907 kg). Trailer brake requirements
vary by local law, consult local legal require -
ments where the trailer is to be towed for trailer
brake requirements.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have a collision.
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure
or tires.

Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission
in PARK. For four-wheel drive vehicles, make sure
the transfer case is not in NEUTRAL. Always, block
or "chock" the 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 :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized.
WARNING!
WARNING!

Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.

STARTING AND OPERATING115
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer
size, stoplights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness. The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.
NOTE:
Disconnect trailer wiring connector from the
vehicle before launching a boat (or any other
device plugged into vehicle’s electrical connect)
into water.

Be sure to reconnect after clear from water area.

Four-Pin Connector Seven-Pin Connector

TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away from
heavy traffic.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do
this could lead to accelerated brake lining wear,
higher brake pedal effort, and longer stopping
distances.

116STARTING AND OPERATING
Automatic Transmission

The DRIVE range can be selected when towing.
The transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, select
TOW/HAUL mode or select a lower gear range (using
the Electronic Range Select (ERS) shift control).

NOTE:Using TOW/HAUL mode or selecting a lower gear
range (using the ERS shift control) while operating
the vehicle under heavy loading conditions will
improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
This action will also provide better engine braking. When towing a loaded trailer up steep grades at
low speeds, holding your vehicle in FIRST gear
(using the ERS shift control) can help to avoid
transmission overheating.
Tow/Haul Mode
To reduce potential for automatic transmission
overheating, activate TOW/HAUL mode when
driving in hilly areas, or select a lower gear range
(using the Electronic Range Select (ERS) shift
control) on more severe grades.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.

STARTING AND OPERATING117
RECREATIONAL TOWING
Recreational towing is allowed ONLY if the
front 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 instructions.

2. Drive the front wheels onto the tow dolly.
3. Firmly apply the parking brake. Place the transmission in PARK.
4. Properly secure the front wheels to the dolly, following the dolly manufacturer's instructions.
5. Release the parking brake.
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 front (driving) wheels.
Traction
When driving on wet or slushy roads, it is possible
for a wedge of water to build up between the tire
and road surface. This is hydroplaning and may
cause partial or complete loss of vehicle control
and stopping ability. To reduce this possibility, the
following precautions should be observed:
Slow down during rainstorms or when the roads
are slushy.
Slow down if the road has standing water or
puddles.
Replace the tires when tread wear indicators
first become visible.
Keep tires properly inflated.
Maintain sufficient distance between your
vehicle and the vehicle in front of you to avoid a
collision in a sudden stop.CAUTION!
DO NOT flat tow this vehicle. Damage to the
drivetrain will result. If this vehicle requires
towing, make sure the drive wheels are OFF
the ground.

Towing this vehicle in violation of the above
requirements can cause severe transmission
damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.

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 carefully whenever there is likely to be
poor traction (ice, snow, wet, mud, loose sand, etc.).

SAFETY141
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Traction Control System (TCS)
TCS monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and
engine power is reduced, to provide enhanced
acceleration and stability. A feature of the TCS,
Brake Limited Differential (BLD) functions similarly 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 torque to be applied to the
wheel that is not spinning. This feature remains
active even if the ESC is in the “Partial Off” mode.
The ESC Activation/Malfunction Indicator Light (in
the instrument cluster) will start to flash as soon as
the tires lose traction and the wheels begin to spin.
This indicates that the TCS is active. If the indicator
light flashes during acceleration, ease up on the
accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the
prevailing road conditions, and do not switch off
the ESC or TCS.
Trailer Sway Control (TSC) — If Equipped
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and apply
the brake of the appropriate wheel(s) to counteract
the sway of the trailer.
NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations
Ú
page 110.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced, and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” mode.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there
may not be enough brake pressure to hold
both the vehicle and the trailer on a hill when
the brake pedal is released. In order to avoid
rolling down an incline while resuming accel -
eration, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.

HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle. Also,
be certain to place the transmission in PARK.

Failure to follow these warnings can result in a
collision or serious personal injury.
WARNING!
The TCS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded.
The TCS cannot prevent collisions, including
those resulting from excessive speed in turns,
or hydroplaning.
The capabilities of a TCS-equipped vehicle
must never be exploited in a reckless or
dangerous manner, which could jeopardize
the user's safety or the safety of others.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.

Overtaking/Passing

The BSM system is designed not to issue an alert
on stationary objects such as guardrails, posts,
walls, foliage, berms, snow banks, car washes, etc.
However, occasionally the system may alert on
such objects. This is normal operation and your
vehicle does not require service.
The BSM system will not alert you of objects that
are traveling in the opposite direction of the vehicle
in adjacent lanes Ú page 256.
Opposing Traffic

Rear Cross Path (RCP)
RCP is intended to aid the driver when backing out
of parking spaces where their vision of oncoming
vehicles may be blocked. Proceed slowly and
cautiously out of the parking space until the rear
end of the vehicle is exposed. The RCP system will
then have a clear view of the cross traffic, and if an
oncoming vehicle is detected, alert the driver.

RCP Detection Zones

RCP monitors the rear detection zones on both
sides of the vehicle, for objects that are moving
toward the side of the vehicle with a minimum
speed of approximately 3 mph (5 km/h), to objects
moving a maximum of approximately 20 mph
(32 km/h), such as in parking lot situations.
WARNING!
The Blind Spot Monitoring system is only an aid
to help detect objects in the blind spot zones.
The BSM system is not designed to detect
pedestrians, bicyclists, or animals. Even if your
vehicle is equipped with the BSM system, always
check your vehicle’s mirrors, glance over your
shoulder, and use your turn signal before
changing lanes. Failure to do so can result in
serious injury or death.

Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped BeltAlert is a feature intended to remind
the driver and outboard front seat
passenger (if equipped with outboard
front passenger seat BeltAlert) to buckle
their seat belts. The BeltAlert feature is active
whenever the ignition switch is in the AVV (START)
or MAR (ACC/ON/RUN) position.
Initial Indication
If the driver is unbuckled when the ignition switch
is first in the AVV (START) or MAR (ACC/ON/RUN)
position, a chime will signal for a few seconds.
If the driver or outboard front seat passenger
(if equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch is
first in the AVV (START) or MAR (ACC/ON/RUN)
position the Seat Belt Reminder Light will turn on
and remain on until both outboard front seat belts
are buckled. The outboard front passenger seat
BeltAlert is not active when an outboard front
passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when
the vehicle is moving above a specified vehicle
speed range and the driver or outboard front seat
passenger is unbuckled (if equipped with outboard
front passenger seat BeltAlert) (the outboard front passenger seat BeltAlert is not active when the
outboard front passenger seat is unoccupied).
The BeltAlert warning sequence starts by blinking
the Seat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warning
sequence has completed, the Seat Belt Reminder
Light will remain on until the seat belts are
buckled. The BeltAlert warning sequence may
repeat based on vehicle speed until the driver
and occupied outboard front seat passenger seat
belts are buckled. The driver should instruct all
occupants to buckle their seat belts.
Change Of Status
If the driver or outboard front seat passenger
(if equipped with outboard front passenger seat
BeltAlert) unbuckles their seat belt while the
vehicle is traveling, the BeltAlert warning sequence
will begin until the seat belts are buckled again.
The outboard front passenger seat BeltAlert is not
active when the outboard front passenger seat is
unoccupied. BeltAlert may be triggered when an
animal or other items are placed on the outboard
front passenger seat or when the seat is folded flat
(if equipped). It is recommended that pets be
restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat
belts, and cargo is properly stowed.
BeltAlert can be activated or deactivated by
an authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
NOTE:If BeltAlert has been deactivated and the driver or
outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) is
unbuckled the Seat Belt Reminder Light will turn
on and remain on until the driver and outboard
front seat passenger seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are equipped
with lap/shoulder belts.
The seat belt webbing retractor will lock only during
very sudden stops or collisions. This feature allows
the shoulder part of the seat belt to move freely
with you under normal conditions. However, in a
collision the seat belt will lock and reduce your risk
of striking the inside of the vehicle or being thrown
out of the vehicle.
WARNING!
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, the air bags won’t
deploy at all. Always wear your seat belt even
though you have air bags.

Lap/Shoulder Belt Operating Instructions

1. Enter the vehicle and close the door. Sit back
and adjust the seat.

2. The seat belt latch plate is above the back of the front seat, and next to your arm in the rear
seat (for vehicles equipped with a rear seat).
Grab the latch plate and pull out the seat belt.
Slide the latch plate up the webbing as far as
necessary to allow the seat belt to go around
your lap.
Pulling Out The Latch Plate

3. When the seat belt is long enough to fit, insert the latch plate into the buckle until you hear a
“click.”

Inserting Latch Plate Into Buckle

4. Position the lap belt so that it is snug and lies low across your hips, below your abdomen. To
remove slack in the lap belt portion, pull up on the shoulder belt. To loosen the lap belt if it is
too tight, tilt the latch plate and pull on the lap
belt. A snug seat belt reduces the risk of sliding
under the seat belt in a collision.

Positioning The Lap Belt

5. Position the shoulder belt across the shoulder and chest with minimal, if any slack so that it
is comfortable and not resting on your neck.
The retractor will withdraw any slack in the
shoulder belt.
6. To release the seat belt, push the red button on the buckle. The seat belt will automatically
retract to its stowed position. If necessary,
slide the latch plate down the webbing to allow
the seat belt to retract fully.
A frayed or torn seat belt could rip apart in a
collision and leave you with no protection.
Inspect the seat belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immedi -
ately. Do not disassemble or modify the seat
belt system. If your vehicle is involved in a
collision, or if you have questions regarding
seat belt or retractor conditions, take your
vehicle to an authorized FCA dealer or autho -
rized FCA Certified Collision Care Program
facility for inspection.
