Jeep Wrangler: Forward Collision Warning (FCW) With Mitigation — If Equipped / Service FCW Warning
If the system turns off, and the instrument
cluster displays:
- ACC/FCW Unavailable Service Required
- Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under
normal conditions, have the system checked by
an authorized dealer.
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that
limits FCW functionality...
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 alert warning on the cluster will stay on until
the tire is inflated to the placard pressure...
Other information:
Observe the following when the diesel engine is
operating:
All message center lights are off.
Malfunction Indicator Light (MIL) is off.

The specified following distance for ACC can be
set by varying the distance setting between four
bars (longest), three bars (long), two bars

distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle
ahead...
