Cadillac 2009 DTS, Owner'S Manual

Page: 124 / 462

SBZA does not operate when the left or right corners
of the rear bumper are covered with mud, dirt, snow, ice,
slush, or in heavy rainstorms. For cleaning instructions,
see Washing Your Vehicle on page 5-90. If the DIC
still displays the SIDE BLIND ZONE SYSTEM
UNAVAILABLE message after cleaning the bumper,
see your dealer/retailer.
The SBZA displays may remain on if a trailer is attached
to the vehicle, or a bicycle or object is extending out
to either side of the vehicle.
When SBZA is disabled for any reason other than the
driver turning it off, the driver will not be able to turn
SBZA back on using the DIC. The SIDE BLIND ZONE
ALERT ON option will not be selectable if the
conditions for normal system operation are not met.
Until normal operating conditions for SBZA are met,
you should not rely upon SBZA while driving.
SBZA Error Messages
The following messages may appear in the DIC:
SIDE BLIND ZONE ALERT SYSTEM OFF:
This message indicates that the driver has turned the
system off.
SIDE BLIND ZONE SYSTEM UNAVAILABLE:
This message indicates that the SBZA system is
disabled because the sensor is blocked and cannot
detect vehicles in the blind zone. The sensor may be
blocked by mud, dirt, snow, ice, slush, or even
heavy rainstorms. This message may also activate
during heavy rain or due to road spray. The vehicle does
not need service. For cleaning, see Washing Your
Vehicle on page 5-90.
SERVICE SIDE BLIND ZONE ALERT SYSTEM: If this
message appears, both SBZA displays will remain on
indicating there is a problem with the SBZA system.
If these displays remain on after continued driving,
the system needs service. Take the vehicle to your
dealer/retailer.
