260SAFETY
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 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.
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 overfilled
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.
SELECTABLE TIRE FILL ALERT (STFA) —
IF EQUIPPED
The 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.
NOTE:To use the STFA feature, the Tire Fill Alert feature must be
enabled through use of the customer settings in the radio.
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.
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.
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 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.
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 overin -
flated or over-deflated.
3. The horn will chirp once again when enough air is added or removed to reach proper selected pressure
level.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the lug nut/bolt torque for tightness. Check the
tires (including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil, or other fluid leaks. Also, if gasoline fumes are
detected or if fuel or brake fluid leaks are suspected, the
cause should be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have an authorized dealer inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO), follow
these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
 If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
 If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
 Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi -
tions repaired promptly. Until repaired, drive with all
side windows fully open.
 When exiting the vehicle, always make sure the igni -
tion is in the OFF position, remove the key fob from
the vehicle and lock your vehicle.

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 two 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
Úpage 246. Once the
vehicle has been freed, push the ESC OFF button again
to restore “ESC On” mode.
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 seconds 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 for
at least one minute after every five rocking-motion
cycles. This will minimize 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 transmis -
sion shifting occurring).
