Pedestrian Emergency Braking (PEB) —
If Equipped
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.
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).
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.
Turning PEB On Or Off
NOTE:
The default status of PEB is “On.” This allows the sys-
tem to warn you of a possible frontal collision with the
pedestrian.
The PEB button is located in the Uconnect display in the
Control settings
page 165.
To turn the PEB system off, push the Pedestrian Emer-
gency Braking button.
To turn the PEB system back on, push the Warning
Active Braking button.
Changing the PEB status to “Off” deactivates the sys-
tem, 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.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
(Vehicles Under 10K Gross Vehicle Weight Rating
(GVWR) Only)
The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
NOTE:
The TPMS Warning Light will illuminate in the instru-
ment cluster and a chime will sound when tire pressure
is low in one or more of the four active road tires. In
addition, the instrument cluster will display a graphic
showing the pressure values of each tire with the low
tire pressure values in a different color, or the Uconnect
radio will display a TPMS message. When this occurs
you must increase the tire pressure to the recom-
mended cold placard pressure in order for the TPMS
Warning Light to turn off.
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 pres-
sure 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 cold tire infla-
tion pressure must not exceed the maximum inflation
pressure molded into the tire sidewall. The tire pressure
will also increase as the vehicle is driven — this is nor-
mal and there should be no adjustment for this
increased pressure.
See page 315 on how to properly inflate the vehi-
cle’s tires.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low-pressure warning
limit for any reason, including low temperature effects
and natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the recom-
mended cold placard pressure. Once the low TPMS
Warning Light illuminates, you must increase the tire
pressure to the recommended cold placard pressure in
order for the TPMS Warning Light to turn off. The sys-
tem will automatically update and the TPMS Warning
Light will turn off once the system receives the updated
tire pressures. The vehicle may need to be driven for up
to 20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
