available. Once the condition that limited the
system performance is no longer present, the
system will return to its full performance state.
If the problem persists, see an authorized
dealer.
Service FCW Warning
If the system turns off, the instrument cluster
displays:
“AEB Unavailable Service Required”
AEB Unavailable Service Required indicates
there is an internal system fault. Although the
vehicle is still drivable under normal conditions,
have the system checked by an authorized
dealer.
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.
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 pedestrian.
The PEB button is located in the Uconnect
display in the Control settings Ú page 207.
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.
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.
