WARNING!
Cargo must be securely tied down before
driving your vehicle. Improperly secured loads
can fly off the vehicle, particularly at high
speeds, resulting in personal injury or
property damage. Follow the roof rack
cautions when carrying cargo on your roof
rack.
CAUTION!
To prevent damage to the roof of your
vehicle, do not carry any loads on the roof
rack without the crossbars installed. The
load should be secured and placed on top
of the crossbars, not directly on the roof. If
it is necessary to place the load on the roof,
place a blanket or some other protection
between the load and the roof surface.
To avoid damage to the roof rack and
vehicle, do not exceed the maximum roof
rack load capacity of 150 lb (68 kgyf$OZD\V
distribute heavy loads as evenly as possible
and secure the load appropriately.
Long loads which extend over the wind-
shield, such as wood panels or surfboards,
or loads with large frontal area should be
secured to both the front and rear of the
vehicle.

Do not tow a trailer at all during the first
500 miles (805 kmyfWKHQHZYHKLFOHLV driven. The engine, axle or other parts could
be damaged.
Then, during the first 500 miles (805 kmyf that a trailer is towed, do not drive over
50 mph (80 km/hyfDQGGRQRWPDNHVWDUWV
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
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 colli -
sion.
When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over -
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, 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.

CYBERSECURITY
Your vehicle may be a connected vehicle and
may be equipped with both wired and wireless
networks. These networks allow your vehicle to
send and receive information. This information
allows systems and features in your vehicle to
function properly. Your vehicle may be equipped with certain
security features to reduce the risk of
unauthorized and unlawful access to vehicle
systems and wireless communications. Vehicle
software technology continues to evolve over
time and FCA US LLC, working with its suppliers,
evaluates and takes appropriate steps as
needed. Similar to a computer or other devices,
your vehicle may require software updates to
improve the usability and performance of your
systems or to reduce the potential risk of
unauthorized and unlawful access to your
vehicle systems.
The risk of unauthorized and unlawful access to
your vehicle systems may still exist, even if the
most recent version of vehicle software (such as
Uconnect softwareyfLVLQVWDOOHG.
WARNING!
It is not possible to know or to predict all of
the possible outcomes if your vehicle’s
systems are breached. It may be possible
that vehicle systems, including safety
related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury
or death.
ONLY insert media (e.g., USB or CDyfLQWR
your vehicle if it came from a trusted
source. Media of unknown origin could
possibly contain malicious software, and if
installed in your vehicle, it may increase the
possibility for vehicle systems to be
breached.
As always, if you experience unusual
vehicle behavior, take your vehicle to the
nearest authorized dealer immediately.

Improper installation can lead to failure of
an infant or child restraint. It could come
loose in a collision. The child could be badly
injured or killed. Follow the child restraint
manufacturer’s directions exactly when
installing an infant or child restraint.

After a child restraint is installed in the
vehicle, do not move the vehicle seat forward
or rearward because it can loosen the child
restraint attachments. Remove the child
restraint before adjusting the vehicle seat
position. When the vehicle seat has been
adjusted, reinstall the child restraint.

When your child restraint is not in use,
secure it in the vehicle with the seat belt or
LATCH anchorages, or remove it from the
vehicle. Do not leave it loose in the vehicle.
In a sudden stop or accident, it could strike
the occupants or seatbacks and cause
serious personal injury.
