SIDE BLIND ZONE SYSTEM
UNAVAILABLE
If your vehicle has the Side Blind
Zone Alert (SBZA) system, this
message displays when the SBZA
system is disabled because the
sensor is blocked and cannot detect
vehicles in your blind zone. The
sensor may be blocked by mud, dirt,
snow, ice, or slush. This message
may also display during heavy rain
or due to road spray. It may also
come on when driving in isolated
areas with no guardrails, trees,
or road signs and light traffic.
Your vehicle does not need service.
For cleaning instructions, see
