Jacking Instructions
Jack Warning Label
1. Remove the spare tire, jack, and tools from the stored location.
2. Using the lug wrench, loosen the wheel nuts (but do not remove), by turning them counterclockwise one turn
while the wheel is still on the ground.
WARNING!

Carefully follow these tire changing warnings to help
prevent personal injury or damage to your vehicle:
• Always park on a firm, level surface as far from the edge of the roadway as possible before raising the vehicle.
• Turn on the Hazard Warning flasher.

• Block the wheel diagonally opposite the wheel to be raised.

• Apply the parking brake firmly and set the transmission in PARK.
• Never start or run the engine with the vehicle on a jack.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack. If you need to get under a raised vehicle, take it to a service center
where it can be raised on a lift.
• Only use the jack in the positions indicated and for lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely stowed, spares must be stowed with the valve stem facing
the ground.

6. Remove the lug nuts and pull the wheel off. Install thespare wheel and lug nuts with the cone shaped end of the
lug nuts toward the wheel. Hand tighten the lug nuts
with vehicle lifted. To avoid the risk of forcing the vehicle
off the jack, do not fully tighten the lug nuts until the
vehicle has been lowered.
7. Lower vehicle to ground, 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.
NOTE:
For the correct lug nut torque refer to “Technical Specifica -
tions” in “Torque Specifications.” If in doubt about the
correct tightness, have them checked with a torque wrench
by an authorized dealer or service station. 8. If your vehicle is equipped with a wheel center cap, install
the cap and remove the wheel blocks. Do not install
chrome or aluminum wheel center caps on the spare
wheel. This may result in cap damage.
9. Lower the jack to its fully closed position. Stow the replaced tire, and secure the jack and tools in the proper
location.
10. Adjust the tire pressure when possible.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.WARNING!
A loose tire or jack thrown forward in a collision or hard
stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.

will not shift out of PARK (P) (such as a dead battery), a
Manual Park Release is available.
Follow these steps to activate the Manual Park Release:
1. Apply firm pressure to the brake pedal while seated inthe driver’s seat.
2. Apply the parking brake if possible.
3. Using a small screwdriver or similar tool, remove the Manual Park Release cover, which is located to the lower

CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on HOT (H),
and you hear continuous chimes, turn the engine off
immediately and call for service.
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the driver’s
seat with your foot firmly on the brake pedal when
activating the Manual Park Release. Activating the
Manual Park Release will allow your vehicle to roll away
if it is not secured by the parking brake, or by proper
connection to a tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other equip-
ment designed for this purpose, following equipment manu-
facturer’s instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main structural
members of the vehicle, not to bumpers or associated
brackets. State and local laws regarding vehicles under tow
must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode. If the key fob is unavailable or the vehicle's battery is
discharged, refer to ”Manual Park Release” in this section for
instructions on shifting the transmission out of PARK for
towing.

SERVICING AND MAINTENANCE 513
(Continued)
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to ensure
optimum transmission performance and life. Use only the
manufacturer’s specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It is
important to maintain the transmission fluid at the correct
level using the recommended fluid. No chemical flushes
should be used in any transmission; only the approved lubri-
cant should be used.
WARNING!
• Use only manufacturer's recommended brake fluid. Refer to “Fluids And Lubricants” in “Technical Speci -
fications” for further information. Using the wrong
type of brake fluid can severely damage your brake
system and/or impair its performance. The proper type
of brake fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
• To avoid contamination from foreign matter or mois -
ture, use only new brake fluid or fluid that has been in
a tightly closed container. Keep the master cylinder
reservoir cap secured at all times. Brake fluid in a open
container absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil unexpect -
edly during hard or prolonged braking, resulting in
sudden brake failure. This could result in a collision.
• Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate thebrake fluid. Brake seal components could be damaged,
causing partial or complete brake failure. This could
result in a collision.
CAUTION!
Using a transmission fluid other than the manufacturer’s
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.

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 features
to reduce the risk of unauthorized and unlawful access to
vehicle systems and wireless communications. Vehicle soft -
ware technology continues to evolve over time and FCA US
LLC, working with its suppliers, evaluates and takes appro -
priate 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 software) is installed.
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, SD card, or CD) into your vehicle if it came from a trusted source. Media of
unknown origin could possibly contain malicious soft -
ware, 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 your nearest authorized dealer
immediately.
