Pedestrian Emergency Braking (PEB)
PEB is a subsystem of the Forward Collision Warning
(FCW) system which provides the driver with audible
warnings and visual warnings, in the instrument cluster
display. It may apply limited automatic braking when it
detects a potential frontal collision with a pedestrian/
cyclist.

PEB Message

If a PEB event begins at a speed below 39 mph (62 km/h),
the system may provide maximum braking to mitigate the
potential collision with a pedestrian/cyclist. If the PEB
event stops the vehicle completely, the system will hold
the vehicle at a standstill for two seconds and then
release the brakes. When the system determines a
collision with the pedestrian/cyclist in front of you is no
longer probable, the warning message will be deactivated.
The minimum speed for PEB activation is 3 mph (5 km/h). Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the system
to warn you of a possible frontal collision with the pedes
-
trian/cyclist.
The PEB button is located in the Uconnect display in the
control settings
Úpage 197.
To turn the PEB system off, push the Pedestrian
Emergency Braking button once.
To turn the PEB system back on, push the Pedestrian
Emergency Braking button again.
Changing the PEB status to “Off” deactivates the system,
so no warning or active braking will be available in case of
a possible frontal collision with the pedestrian/cyclist.
NOTE:The PEB system will retain the last setting selected by the
driver after ignition shut down. The system will not reset to
the default setting when the vehicle is restarted.
Intersection Collision Assist (ICA) —
If Equipped
ICA uses three front radar sensors located in the front
fascia/bumper, to detect oncoming vehicles from the front
or side when driving through an intersection. When the
system determines that a collision is probable when
turning across oncoming traffic, the system will attempt to
mitigate a possible collision by decelerating the vehicle.
When the system determines that a collision with a
crossing vehicle is probable, the system may apply
additional braking to supplement the driver braking input
to attempt to mitigate a possible collision. The system will
also provide audible warnings and visual warnings (shown
in the instrument cluster). If the driver determines
acceleration is needed to avoid a collision, when the
accelerator is pressed ICA will cancel.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire pressure based
on the vehicle recommended cold tire pressure.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after a
three-hour period. The tire pressure will also increase as
the vehicle is driven — this is normal and there should be
no adjustment for this increased pressure.
WARNING!
Pedestrian Emergency Braking (PEB) is not intended to
avoid a collision on its own, nor can PEB detect every
type of potential collision with a pedestrian. The driver
has the responsibility to avoid a collision by controlling
the vehicle via braking and steering. Failure to follow
this warning could lead to serious injury or death.

256SAFETY
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.
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 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
greater than or equal to 15 psi to XX 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 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. The hazard lights 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 lights 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.
OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your vehicle
are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
 Seat Belt Systems
 Supplemental Restraint Systems (SRS) Air Bags
 Child Restraints
Some of the safety features described in this section may
be standard equipment on some models, or may be
optional equipment on others. If you are not sure, ask an
authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
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.
