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

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 the
Vehicle” under Exterior Care on
page 10‑93. 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.
