Occupant Restraint Systems; Occupant Restraint Systems Features; Important Safety Precautions - Jeep GRAND CHEROKEE L 2023 Owner's Manual

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 ≥15 psi to XX 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 user is required to
wait until the hazard lights STOP flashing or 26-30
seconds after the desired pressure is achieved in
one wheel before switching to another.
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
overinflated or over-deflated.
3. The horn will chirp once again when enough air
is added or removed to reach proper selected
pressure level.

Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passengers
as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air bag:
1. Children 12 years old and under should
always ride buckled up in the rear seat of a
vehicle with a rear seat.
2. A child who is not big enough to wear the
vehicle seat belt properly must be secured in
the appropriate child restraint or
belt-positioning booster seat in a rear seating
position Ú page 289.
