Service FCW Warning
If the system turns off, and the instrument cluster display
reads:
•
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.
“Wipe Front Radar Sensor In Front Of Vehicle” Warning
The “FCW Front Radar Sensor Temporarily Blocked”
warning will display when conditions temporarily limit
system performance. This most often occurs at times of
poor visibility, such as in snow or heavy rain. The system
may also become temporarily blinded due to obstructions,
such as mud, dirt or ice. In these cases, the instrument
cluster display will read “FCW Front Radar Sensor Tem-
porarily Blocked” and the system will deactivate.
The “FCW Front Radar Sensor Temporarily Blocked” mes-
sage can sometimes be displayed while driving in highly
reflective areas (i.e. tunnels with reflective tiles, or ice and
snow). The system will recover after the vehicle has left
these areas. Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this warning
may temporarily occur.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located behind the lower
grille. In absence of visible obstructions on the bumper, it
could be necessary to wipe off the radar directly on the
surface, after having the radar cover removed. It’s recom-
mended that your authorized dealer perform this opera-
tion.
NOTE:
•
If the “FCW Front Radar Sensor Temporarily Blocked”
message occurs frequently (e.g. more than once on every
trip) without any snow, rain, mud, or other obstruction,
have the radar sensor realigned at your authorized
dealer.
•
Installing a snow plow, front-end protector, an aftermar-
ket grille or modifying the grille is not recommended.
Doing so may block the sensor and inhibit FCW opera-
tion.
