How the System Works
The instrument cluster may
have a Park Assist display with
bars that show“distance to
object,” driving direction, and
object location information for
the Park Assist system. As the
object gets closer, more bars
light up and the bars change
color from yellow to amber
to red.
Beeps sound to warn the
driver of certain objects that
are detected around the
vehicle. The frequency of
beeps increases as the vehicle
gets closer to the object.
When the object is very close
to the vehicle, the beeps are
continuous. Beeps for the
front are higher pitched than
beeps for the rear. If equipped
with Safety Alert seat, both
sides of the seat will pulse
alongside the beeps. When the System Does Not
Seem to Work Properly
The following messages may
be displayed on the DIC:
SERVICE PARKING ASSIST :
If this message occurs, check
the following conditions:
.The sensors are not clean.
Keep the vehicle's rear
bumper free of mud, dirt,
snow, ice, and slush. For
cleaning instructions, see
Exterior Care
0455.
.The Park Assist sensors are
covered by frost or ice.
Frost or ice can form around
and behind the sensors and
may not always be seen; this
can occur after washing the
vehicle in cold weather. The
message may not clear until
the frost or ice has melted.
If the above conditions do not
exist, take the vehicle to your
dealer to repair the system. PARK ASSIST OFF :
If the PA
system does not activate due
to a temporary condition, the
appropriate message displays
on the DIC. PA OFF message
is displayed when disabled by
the driver. Front/Rear PA OFF
message is displayed when an
attached object is detected in
the front or rear respectively.
PA Temporarily Unavailable
message is displayed for
system failures. This can occur
under the following conditions:.The driver has disabled the
system.

deceleration. Continue to
apply the brake pedal as
needed.
Tailgating Alert
The vehicle ahead indicator
will display amber when you
are following a vehicle ahead
much too closely.
Selecting the Alert Timing
The Collision Alert control is
on the steering wheel. Press
[to set the FCA timing to
Far, Medium, or Near. The first
button press shows the
current setting on the DIC. Additional button presses will
change this setting. The
chosen setting will remain until
it is changed and will affect
the timing of both the Collision
Alert and the Tailgating Alert
features. The timing of both
alerts will vary based on
vehicle speed. The faster the
vehicle speed, the farther
away the alert will occur.
Consider traffic and weather
conditions when selecting the
alert timing. The range of
selectable alert timings may
not be appropriate for all
drivers and driving conditions.
If your vehicle is equipped with
Adaptive Cruise Control (ACC),
changing the FCA timing
setting automatically changes
the following gap setting (Far,
Medium, or Near).
Following Distance
Indicator
The following distance to a
moving vehicle ahead in your
path is indicated in following
time in seconds on the DriverInformation Center (DIC). See
Driver Information Center
(DIC) (Base Level)
0129 or
Driver Information Center
(DIC) (Uplevel) 0132. The
minimum following time is
0.5 seconds away. If there is
no vehicle detected ahead,
or the vehicle ahead is out of
sensor range, dashes will be
displayed.
Unnecessary Alerts
FCA may provide unnecessary
alerts for turning vehicles,
vehicles in other lanes, objects
that are not vehicles,
or shadows. These alerts are
normal operation and the
vehicle does not need service.

seem to operate properly, this
may correct the issue:
.Clean the outside of the
windshield in front of the
rearview mirror.
