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
威
as a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLIS
威
is not a replacement for
careful driving and only an assist.
Once the blockage is removed, the system will require some driving time
and detection of at least two vehicle objects prior to resetting or the
driver can cycle the ignition key. 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 radar is dirty or
obstructed in some way
Clean the fascia area in front of
the radar, either side, or remove
obstruction.
The surface of the 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
威
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 reset
to an unblocked state once the
rainfall/snowfall rate decreases or
stops. Do not use BLIS
威
and/or
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.
