Side Blind Zone Alert (SBZA)
If equipped, the SBZA 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. 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 blind zone. If the
turn signal is activated and avehicle is also
detected on the same side, the display will flash
a
s an extra warning not to change lanes. Since
this system is part of the Lane Change Alert
(LCA) system, read the entire LCA section before
using this feature.
Lane Change Alert (LCA)
{ Warning
L
CA 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.
If equipped, the LCA system is alane-changing
aid that assists drivers with avoiding lane
change crashes that occur with moving vehicles
in the side blind zone (or spot) areas or with
vehicles rapidly approaching these areas from
behind. The LCA warning display will light up in
the corresponding outside mirror and will flash
if the turn signal is on.
Side Blind Zone Alert (SBZA) is included as part
of
the LCA system.
