Cadillac DTS Owner Manual - 2011
The SBZA detection zones do not change if the vehicle
is towing a trailer. So be extra careful when changing
lanes while towing a trailer.
How the System Works
Left Side Mirror Display Right Side Mirror Display
When the vehicle is started, both outside mirror displays
will briefly come on to indicate that the system is
operating. While driving forward, the left or right side
mirror SBZA display will light up if a vehicle is detected
in that blind zone. If you activate a turn signal and a
vehicle has been detected on the same side, the SBZA
display will flash to give you extra warning not to
change lanes.
SBZA displays do not come on while the vehicle is
approaching or passing other vehicles. At speeds
greater then 20 mph (32 km/h), SBZA displays may
come on when a vehicle you have passed remains in or
drops back into the detection zone.
SBZA can be disabled through the Driver Information
Center (DIC). See Driver Information Center (DIC)
on
page 4‑59
for more information. If the SBZA is disabled
by the driver, the SBZA mirror displays will not light up
during normal driving.
When the System Does Not Seem To Work
Properly
Occasional missed alerts can occur under normal
circumstances and will increase in wet conditions.
The system does not need to be serviced due to an
occasional missed alert. The number of missed alerts
will increase with increased rainfall or road spray.
If the SBZA displays do not light up when the system is
on and vehicles are in the blind zone, the system may
need service. Take the vehicle to your dealer.
SBZA is designed to ignore stationary objects; however,
the system may occasionally light up due to guard rails,
signs, trees, shrubs, and other stationary objects. This
is normal system operation, the vehicle does not need
service.
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 6‑98
. If the DIC
still displays the SIDE BLIND ZONE SYSTEM
UNAVAILABLE message after cleaning the bumper,
see your dealer.
