System Lights and Messages
E142442
The BLIS and cross traffic alert systems
illuminate a yellow alert indicator in the
outside mirror on the side of the vehicle
the approaching vehicle is coming from.
Note: The alert indicator dims when
nighttime darkness is detected.
Cross traffic alert also sounds an audible
warning and a message appears in the
information display indicating a vehicle is
coming from the right or left. Cross traffic
alert works with the reverse sensing
system which sounds its own series of
tones. See Parking Aid (page 182).
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.

Driving Aids
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.
E142443
The system uses radar sensors which are
located behind the bumper fascia on each
side of your vehicle. Do not allow these
areas to become obstructed by mud, snow
or bumper stickers, as this can cause
degraded system performance.
If the system detects a degraded
performance condition, a message
warning of a blocked sensor or a message
warning of low visibility will appear in the
information display and the alert indicator
illuminates in the appropriate mirror(s). The
information display warning can be cleared
but the alert indicator remains illuminated.
When the blockage is removed, the
system can be reset in two ways:
• when at least two objects are detected
while driving, or
• turn the ignition from on to off, then
back on.
If the blockage is still present after the key
cycle, the system senses again that it is
blocked after driving in traffic.
