Jack Location
The scissor-type jack and tire changing tools are located in
the rear cargo area, below the load floor.
NOTE:The funnel for the Cap-Less Fuel System is located
on top of the spare tire. If your vehicle is out of fuel and an
auxiliary fuel can is needed, insert the funnel into the filler
neck and proceed to fill the vehicle. For vehicles not
equipped with a spare tire, the fuel filler funnel is stored in
the left storage bin under the load floor. For more informa-
tion on the Cap-Less Fuel System, refer to “Refueling The
Vehicle” in “Starting And Operating”.
Spare Tire Stowage
The spare tire is stowed under the load floor in the rear
cargo area and is secured to the body with a special wing
nut.
Preparations For Jacking

WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
9. Lower the vehicle by turning the jack screw counter- clockwise, and remove the jack and wheel blocks.
10. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until
each nut has been tightened twice. For correct lug nut
torque, refer to “Torque Specifications” in “Technical
Specifications”. If in doubt about the correct tightness,
have them checked with a torque wrench by an autho-
rized dealer or at a service station.
11. Lower the jack to the fully closed position and return it and the tools to the proper positions in the foam tray.
12. Remove the small center cap and securely store the road wheel in the cargo area. 13. Have the aluminum road wheel and tire repaired as
soon as possible, properly secure the spare tire with the
special wing nut torqued to 3.7 ft-lbs (5 N·m), reinstall
the jack and tool kit foam tray, and latch the rear load
floor cover.
NOTE: Do not drive with the spare tire installed for more
than 50 miles (80 km) at a max speed of 50 mph (80 km/h).

5. Remove the filter cover by disengaging the retaining taband mid way snap that secures the filter cover to the
HVAC housing. Disengage the mid way snap by pulling
the door outward. Unhinge the filter cover on the right
side to fully remove the cover. 6. Remove the A/C air filter by pulling it straight out of
the housing.
7. Install the A/C air filter with the arrow on the filter pointing toward the floor. When installing the filter
cover, make sure the retaining tabs fully engage the
cover.

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 informa-
tion. This information allows systems and features in your
vehicle to function properly.
Your vehicle may be equipped with certain security fea-
tures 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 com-
puter 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 software) is
installed.

NOTE:
•FCA US LLC or your dealer may contact you directly
regarding software updates.
• To help further improve vehicle security and minimize
the potential risk of a security breach, vehicle owners
should:
• Routinely check www.driveuconnect.com (U.S. Resi-
dents) or www.driveuconnect.ca (Canadian Residents)
to learn about available Uconnect software updates.
• Only connect and use trusted media devices (e.g.
personal mobile phones, USBs, CDs).
Privacy of any wireless and wired communications cannot
be assured. Third parties may unlawfully intercept infor-
mation and private communications without your consent.
For further information, refer to “Data Collection & Pri-
vacy” in your Uconnect Owner ’s Manual Supplement or
“Onboard Diagnostic System (OBD II) Cybersecurity” in
“Getting To Know Your Instrument Panel”.UCONNECT SETTINGS

touchscreen and buttons on the faceplate located on the
center of the instrument panel that allow you to access and
change the customer programmable features. Many fea-
tures can vary by vehicle.
