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.
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
Clean the fascia area in front of
the radar, either left or right side,
or remove obstruction.
The surface of the left or right
radar is not dirty or obstructed
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.
Heavy rainfall or heavy snowfall is
interfering with the radar signals
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.
Due to the nature of radar technology, it is possible to get a blockage
warning and not be blocked. This is rare and known as a false blockage
warning. A false blocked condition will either self clear or clear after a
key cycle.
Day and night brightness
The BLIS-CTA alert will automatically dim when the headlamp switch is
in the parking, on, or autolamp position, and night time darkness has
been detected by the sun sensor.
