GM YUKON XL Automobile User Manual


 
SBZA displays do not come on while the vehicle is
approaching or passing other vehicles. At speeds
greater then 32 km/h (20 mph), 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 447
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 6112
. If the DIC still
displays the SIDE BLIND ZONE SYS. UNAVAILABLE
message after cleaning the bumper, see your dealer.
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.
