SBZA Detection Zone
2. LCA Detection Zone
When towing atrailer, LCA feature is disabled.
When not towing atrailer, the LCA sensor
covers azone of approximately one lane over
from both sides of the vehicle, or 3.5 m (11
ft). The height of the zone is approximately
between 0.5 m (1.5 ft) and 2 m (6 ft) off
the ground. Drivers are also warned of
vehicles rapidly approaching this area up to
approximately 70 m (230 ft) behind the vehicle.
Trailer Side Blind Zone Area (TSBZA)
If equipped, the TSBZA system is alane-
changing aid that assists drivers with avoiding
crashes that occur with moving vehicles in the
side blind zone, or blind spot areas. The trailer
side blind zone area adds the blind zone area
along the side of atrailer that the host vehicle
is pulling.
When the vehicle is in a forward gear, the left or
right side mirror display will light up if a moving
vehicle is detected in that trailer blind zone.
If the turn signal is activated and avehicle is
also detected on the same side, the display will
flash as an extra warning not to change lanes.
Since this system is part of the Lane Change
Al
ert system, read the entire Lane Change Alert
section before using this feature.
{ Warning
T
SBZA does not alert the driver to vehicles
ou
tside of the system detection zones,
pedestrians, bicyclists, or animals. It may
not provide alerts when changing lanes
under all driving conditions. Failure to
use proper care when changing lanes may
result in injury, death, or vehicle damage.
Before making a lane change, always check
mirrors, glance over your shoulder, and use
the turn signals.

The Side Blind Zone Alert (SBZA) warning
ar
ea starts at approximately the middle of
the vehicle and goes back 5 m(16 ft). The
Trailer Side Blind Zone Alert (TSBZA) warning
area starts at approximately 3 m (10 ft) to the
trailing edge of the vehicle and goes back up to
21 m (69 ft) behind the vehicle. The maximum
trailer length is 12 m (39 ft).
How the System Works
The LCA/TSBZA symbol lights up in the side
mirrors when the system detects amoving
vehicle in the next lane over that is in the trailer
side blind zone. This indicates it may be unsafe
to change lanes. Before making alane change,
check the SBZA display, check mirrors, glance
over your shoulder, and use the turn signals.
