Collision Alert
When your vehicle approaches another
de
tected vehicle too rapidly, the red FCA
display will flash on the windshield. Also, eight
rapid high-pitched beeps will sound from the
front, or the Safety Alert Seat will pulse five
times. When this Collision Alert occurs, the

occur more rapidly which can cause a brief, mild
d

The Collision Alert control is on the steering
wheel. Press [ to set the FCA timing to Far,

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

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).

are not vehicles, or shadows. These alerts are
normal operation and the vehicle does not
need service.

properly, this may correct the issue:
