SAFETY291
Selectable Tire Fill Alert (STFA) — 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 the customer to select a
pressure to inflate or deflate the vehicle's front
and rear axle tires to and to provide feedback to
the customer 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, the customer 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.
The customer may also store the pressure
values chosen for each axle in the radio as a
preset pressure. The customer will be allowed
to store up to two sets of preset values in the
radio for the front and rear axle pressure values. Once the customer selects the tire pressures for
the front and rear axles that they want to inflate
or deflate to, they 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 RUN
mode, with the transmission in PARK (P).
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 or deflating the tire, the TPMS sensor
may be in a null spot preventing the TPMS
sensor signal from being received. In this case,
the vehicle may need to be moved either
forward or backward slightly to exit the null spot.
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 when the selected
pressure is reached to let the user know
when to stop inflating or deflating the tire.
The horn will chirp three times if the tire is
overinflated or over deflated and will
continue to chirp every five seconds if the
user continues to inflate or deflate the tire.
The horn will chirp once again when enough
air is added or removed to reach proper
selected pressure level.
Tire Pressure Information System (TPIS)
3500/4500/5500 Series Trucks
Your vehicle may be equipped with a Tire
Pressure Information System (TPIS).
The Tire Pressure Information System (TPIS)
uses wireless technology with wheel rim
mounted electronic sensors to transmit tire
pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire
pressure readings to the receiver module.

IN CASE OF EMERGENCY349
To Reset The Manual Park Release:

1. Push the locking tab to the right, to unlock
the lever.

2. Rotate the Manual Park Release lever forward to its original position, until the
locking tab snaps into place to secure the
lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed
position.
4. Re-install the access 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. Then shift
back and forth between DRIVE (D) and REVERSE
(R), 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 trucks equipped with an 8–speed trans
-
mission, shifts between DRIVE and REVERSE
can only be achieved at wheel speeds of
5 mph (8 km/h) or less. Whenever the trans -
mission remains in NEUTRAL (N) for more
than two seconds, you must press the brake
pedal to engage DRIVE or REVERSE.

Push the ESC OFF switch, to place the
Electronic Stability Control (ESC) system in
“Partial Off” mode, before rocking the vehicle

Ú
page 274. Once the vehicle has been freed,
push the ESC OFF switch 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 transmission failure during
prolonged efforts to free a stuck vehicle.

When “rocking” a stuck vehicle by shifting
between DRIVE 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 over -
heating 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).

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.

Based on engine operation conditions, the
oil change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as frequent
short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required”
message is displayed. Have your vehicle serviced
as soon as possible, within the next 500 miles
(805 km).
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change.
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look
for unusual wear or damage. Rotate at the
first sign of irregular wear.
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and
automatic transmission (six-speed only), and
fill as needed.

Check function of all interior and exterior lights.
