Chevrolet 2009 Tahoe Automobile User Manual


 
SBZA can be disabled through the Driver Information
Center (DIC). See Driver Information Center (DIC)
on page 3-51 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/retailer.
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 5-110. If the DIC still
displays the SIDE BLIND ZONE SYS. 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.
