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:
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from
rain, snow, or high humidity accumulating on
the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze)
to enter the radiator...
NOTE:
In four door models, the rear door frames must
be removed first, followed by the front door
frames.
Using the provided #40 Torx head driver
and ratchet, loosen the Torx screws
located on the underside of each door
frame (two per door)...
