Driving and Operating
9-45
SBZA displays do not come on
while the vehicle is approaching or
passing other vehicles. At speeds
greater than 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
Vehicle Personalization.
See Vehicle Personalization on
page 5‑39 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, or slush, or in
heavy rainstorms. For cleaning
instructions, see Exterior Care on
page 10‑92. If the infotainment
display still shows 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 Vehicle
Personalization. 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.
