Owner's Manual

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 go unblocked
once the rainfall/snowfall rate decreases
or stops. Do not use BLIS威-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.
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威 offifthe
false alerts become annoying.
Day and night brightness
The BLIS威-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.
