How the System Works
Left Side Mirror 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 can be disabled through
vehicle personalization. See
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
Display
to Work Properly
SBZA displays may not come on
when passing a vehicle quickly.
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.
Driving and Operating
SBZA is designed to ignore
stationary objects; however, the
for 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
. If the SIDE
DETECTION SYSTEM
UNAVAILABLE message still
displays 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.
