System Lights and Messages
Note: The alert indicator dims when nighttime darkness is detected.
CTA also sounds an audible alarm and a message appears in the
information display indicating a vehicle is coming from the right or left.
CTA works with the reverse sensing system which sounds its own
audible alarm; see the Parking Aids chapter.
System Sensors
WARNING: Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLIS® as a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLIS® is not a replacement for
careful driving and only an assist.
Note: It is possible to get a blockage warning with no blockage present;
this is rare and known as a false blockage warning. A false blocked
condition either self-corrects or clears after a key cycle.

Driving Aids
The BLIS® and CTA systems
illuminate a yellow alert indicator in
the outside mirror on the side of
the vehicle the approaching vehicle
is coming from.
The system uses radar sensors
which are located behind the
bumper fascia on each side of the
vehicle. Do not allow these areas to
become obstructed by mud, snow or
bumper stickers, as this can cause
degraded system performance.
