Vehicles With A Full-Size Matching Spare

1. If your vehicle is equipped with a matching full-size spare wheel and tire assembly, it has
a Tire Pressure Monitoring System sensor,
and can be monitored by the Tire Pressure
Monitoring System (TPMS) when swapped
with a low pressure road tire.

2. In the event that the matching full-size spare tire is swapped with a low pressure road tire,
the next ignition switch cycle will still show the
TPMS Warning Light to be on, a chime to
sound, an “Inflate to XX” message to appear in
the instrument cluster, and the graphic display
will still show the low tire pressure value in a
different color.
3. Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn off the TPMS
Warning Light as long as none of road tires are
below the low pressure warning threshold.
TIRE FILL ALERT
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the
tire.
The customer may choose to disable or enable the
Tire Fill Alert feature in the apps menu of the
Uconnect system.
NOTE:
Only one tire can be filled at a time when using
the Tire Fill Alert system.

The Tire Fill Alert feature cannot be entered if an
existing TPMS system fault is set to “active” or if
the system is in deactivation mode (if equipped).

The system will be activated when the system
detects an increase in tire pressure while filling the
tire. The ignition must be in the ON/RUN mode with
the transmission in PARK for vehicles equipped
with an automatic transmission. For vehicles
equipped with a manual transmission, the parking
brake must be applied.
NOTE:It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode. If the hazard lamps
do not come on while inflating the tire, the Tire
Pressure Monitoring System (TPMS) sensor may
be in an inoperative position, preventing the TPMS
sensor signal from being received. In this case, the
vehicle may need to be moved slightly forward or
backward. The Tire Fill Alert system will only inflate or deflate
one tire at a time. Wait until the hazard lights have
stopped flashing for 30 seconds after the desired
pressure is achieved in one tire before switching to
another.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
Operation:
The horn will chirp once to let the user know
when to stop filling the tire, when it reaches
recommended pressure.
The horn will chirp three times if the tire is over
-
filled and will continue to chirp every five
seconds if the user continues to inflate the tire.
The horn will chirp once again when enough air
is let out to reach proper inflation level.
The horn will also chirp three times if the tire is
then underinflated and will continue to chirp
every five seconds if the user continues to
deflate the tire.
NOTE:The Tire Fill Alert feature is set to “Disabled” every
time the ignition is turned to “OFF”. To re-enable
the Tire Fill Alert feature at the next ignition “RUN”
state, the customer must re-enable the feature
through use of the customer settings in the radio.

298SAFETY
SELECTABLE TIRE FILL ALERT — IF EQUIPPED
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the
normal Tire Fill Alert system. The system is
designed to allow you to select a pressure to inflate
or deflate the vehicle's front and rear axle tires to,
and to provide feedback while inflating or deflating
the vehicle's tires.
In the Selectable Tire Fill Alert application, which is
located in the apps menu of the Uconnect system,
you will be able to select a pressure setting for both
the front and rear axle tire pressures by scrolling
through a pressure range from XX to 15 psi in 1 psi
increments for each axle setting.
XX = the vehicle's cold placard pressure values for
the front and rear axles as shown on the vehicle
placard pressure label.
NOTE:The Tire Fill Alert feature disables every time the
ignition is placed in the OFF position. The feature
must be re-enabled through the radio each time
the ignition is placed back in the ON/RUN position
Úpage 215.
You may also store pressure values chosen for
each axle in the Uconnect system application as
preset pressure values. Up to two sets of preset
pressure values can be stored in the Uconnect
system for the front and rear axle. Once you select
the tire pressures for the front and rear axles that you want to inflate or deflate to, you can begin
inflating or deflating one tire at a time.
NOTE:The STFA system will only support inflating or
deflating one tire at a time.
In order to use STFA, the Tire Fill Alert feature must
be enabled through the radio Ú
page 215.
The system will be activated when the TPMS
receiver module detects a change in tire pressure.
The ignition must be in the ON/RUN mode, with the
transmission in PARK in vehicles with an automatic
transmission, and in NEUTRAL with the parking
brake engaged in vehicles with a manual
transmission. The hazard lamps will come on to
confirm the vehicle is in Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire
pressure screen will be displayed in the instrument
cluster. If the hazard lamps do not come on while
inflating or deflating the tire, the Tire Pressure
Monitoring System (TPMS) sensor may be in an
inoperative position, preventing the TPMS sensor
signal from being received. In this case, the vehicle
may need to be moved slightly forward or
backward.
The STFA system will only inflate or deflate one tire
at a time. Wait until the hazard lights have stopped
flashing for 30 seconds after the desired pressure
is achieved on one tire before switching to another. Horn chirps will indicate STFA status as tires are
inflated/deflated. The horn will chirp under the
following STFA states:

1. The horn will chirp once when the selected
pressure is reached to let you know when to
stop inflating or deflating the tire.

2. The horn will chirp three times if the tire is overinflated or over-deflated.
3. The horn will chirp once again when enough air is added or removed to reach proper selected
pressure level.
TPMS DEACTIVATION — IF EQUIPPED
The TPMS can be deactivated if replacing all four
wheel and tire assemblies (road tires) with wheel
and tire assemblies that do not have TPMS
sensors, such as when installing winter wheel and
tire assemblies on your vehicle.
To deactivate the TPMS, first replace all four wheel
and tire assemblies (road tires) with tires not
equipped with Tire Pressure Monitoring System
(TPMS) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then remain on. The
instrument cluster will display the “SERVICE TIRE
PRESSURE SYSTEM” message and then display
dashes (--) in place of the pressure values.

3. Tuck the tether strap into the base of the
console, and reinstall the cover.
FREEING A STUCK VEHICLE

If your vehicle becomes stuck in mud, sand or snow,
it can often be moved using a rocking motion. Turn
the steering wheel right and left to clear the area
around the front wheels. For vehicles with
automatic transmission, push and hold the lock
button on the gear selector. Then, shift back and
forth between DRIVE (D) and REVERSE (R) (with
automatic transmission) or SECOND (2) gear and
REVERSE (R) (with manual transmission), while
gently pressing the accelerator. Use the least
amount of accelerator pedal pressure that will
maintain the rocking motion, without spinning the
wheels or racing the engine.

NOTE:
For vehicles with automatic transmission: Shifts
between DRIVE (D) and REVERSE (R) can only
be achieved at wheel speeds of 5 mph (8 km/h)
or less. Whenever the transmission remains in
NEUTRAL(N) for more than 2 seconds, you must
press the brake pedal to engage DRIVE (D) or
REVERSE (R).
Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle Ú page 281.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are operable, disabled
vehicles may also be towed as described on Ú
page 205.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle and
tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than
30 mph (48 km/h) or for longer than 30 sec-
onds continuously without stopping when you
are stuck and do not let anyone near a spinning
wheel, no matter what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL (N) for at least one minute after
every five rocking-motion cycles. This will mini -
mize overheating and reduce the risk of clutch
or transmission failure during prolonged
efforts to free a stuck vehicle.When “rocking” a stuck vehicle by shifting
between DRIVE/SECOND gear and REVERSE,
do not spin the wheels faster than 15 mph
(24 km/h), or drivetrain damage may result.

Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/h) while
in gear (no transmission shifting occurring).

IN CASE OF EMERGENCY351
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow bars
and other equipment designed for this purpose,
following equipment manufacturer’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 fascia/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 position, not the ACC
position.
If the vehicle's battery is discharged, instructions
on shifting the automatic transmission out of
PARK (P) in order to move the vehicle Úpage 348.
FOUR–WHEEL DRIVE MODELS
FCA LLC US recommends towing with all wheels
OFF the ground. Acceptable methods are to tow
the vehicle on a flatbed or with one end of the
vehicle raised and the opposite end on a towing
dolly.
If flatbed equipment is not available and the
transfer case is operable, the vehicle may be
towed (in the forward direction, with ALL wheels on
the ground), IF the transfer case is in NEUTRAL (N)
and the transmission is in PARK (P) (for automatic
transmissions) or in gear ( NOT in NEUTRAL , for
manual transmissions) Ú page 205.
WITHOUT THE KEY FOB
Special care must be taken when the vehicle is
towed with the ignition in the OFF position. The only
approved method of towing without the key fob is
with a flatbed truck. Proper towing equipment is
necessary to prevent damage to the vehicle.
EMERGENCY TOW HOOKS —

Front Tow Hooks

NOTE:Depending on vehicle trim level, rear tow hooks
may vary.
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flatbed truck,
do not attach to front or rear suspension
components. Damage to your vehicle may
result from improper towing.
CAUTION!
Front or rear wheel lifts must not be used (if
the remaining wheels are on the ground).
Internal damage to the transmission or
transfer case will occur if a front or rear wheel
lift is used when towing.
Towing this vehicle in violation of the
