Once blockage is removed, the system will require some driving time and
detection of at least two vehicle object prior to realizing it is unblocked,
or the driver can cycle the ignition key. If blocked and the ignition key is
cycled, the system resets to unblocked. If however blockage is still
present after the key cycle, the system will sense again that it is blocked
after driving in traffic.
The following table lists possible causes and actions for this message
being displayed:
The surface of the left or right
radar is dirty or obstructed in
some way
The surface of the left or right
radar is not dirty or obstructed
Heavy rainfall or heavy snowfall is
interfering with the radar signals
Trailer tow false alerts
When towing a trailer the left and right sensor may detect the trailer
thus causing a false alert. It may be desirable to turn the BLIS™ system
off if the false alerts become annoying.
Day and night brightness
The BLIS™-CTA amber alert will automatically dim when the headlamp
switch is in PARK, ON, or AUTO ON and night time darkness has been
detected by the sun sensor.
ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with a full-time All Wheel Drive (AWD)
system. The AWD system is an active system, meaning it not only
responds to wheel slip between the front and rear axles but also has the
ability to anticipate wheel slip and transfer torque to the rear wheels
before slip occurs. The AWD system is active all the time and requires no
input from the operator.

Clean the fascia area in front of
the radar, either left or right side,
or remove obstruction.
Drive normally in traffic for a few
minutes to allow the radar to
detect that it is no longer blocked.
Note, the vehicle must be in D
(Drive) and a few vehicles must
pass so that the BLIS™ can clear a
blocked state.
No action required by the driver.
The system will automatically go
unblocked once the
rainfall/snowfall rate decreases or
stops. Do not use BLIS™-CTA in
heavy rainfall or heavy snowfall.
