sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
When your vehicle approaches
another vehicle too rapidly, the red
FCA display will flash and sound
several high-pitched beeps from the
front. When this occurs, the brake
system prepares for driver braking
to occur more rapidly. Continue to
apply the brake pedal as the driving
situation dictates.

Tailgating Alert

The red FCA display will stay
continuously illuminated when
following a vehicle ahead much too
closely.

Selecting the Alert Timing

The Collision Alert control is on the
steering wheel. Press COLLISION

medium, near or off. The first button
press shows the current control
setting on the DIC. Additional button
presses will change this setting. The
chosen setting will remain until it is
changed and will affect 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 further away the alert will occur.
Consider traffic and weather
conditions when selecting the alert
timing. The range of selectable alert
timing may not be appropriate for all
drivers and driving conditions.

Unnecessary Alerts

FCA may sometimes set
unnecessary alerts to 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.
