SBZA Detection Zones
The SBZA sensor covers a zone of approximately
one lane over from both sides of the vehicle,
3.5 m (11 ft). This zone starts at each side mirror and
goes back approximately 16 ft. (5.0 m). The height of
the zone is approximately between 0.5 m (1.5 ft) and
2.0 m (6 ft) off the ground.
Use caution while changing lanes when towing a trailer,
as the SBZA detection zones do not change when a
trailer is towed.
How the System Works
Left Side Mirror Display Right Side Mirror Display
When the vehicle is started, both outside mirror
displays will briefly come on to indicate that the system
is operating. When the vehicle is moving forward, the
left or right side mirror SBZA display will light up if a
vehicle is detected in that blind zone.
If the turn signal is activated and a vehicle is also
detected on the same side, the SBZA display will flash
to give you extra warning not to change lanes.
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 4‑41
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.
