Navigation System; Alert (Sbza) - GMC 2011 Yukon/Yukon XL Owner's Manual

Press to set the speed and
activate cruise control or make the
vehicle decelerate.
Press to disengage cruise
control without erasing the set
speed from memory.
See Cruise Control on page 9 60.
The vehicle's navigation system
(if equipped) provides detailed maps
of most major freeways and roads.
After a destination has been set,
the system provides turn-by-turn
instructions for reaching the
destination. In addition, the system
can help locate a variety of points
of interest (POI), such as banks,
airports, restaurants, and more.
See the Navigation System manual
for more information.
If available, this feature will alert you
to vehicles located in the vehicle's
side blind zone. When the system
detects a vehicle in the side blind
zone, an amber SBZA display will
light up in the corresponding outside
side mirror.
The system is enabled at every
vehicle startup. It can be disabled
through the Driver Information
Center (DIC).
If the message SIDE BLIND ZONE
SYSTEM UNAVAILABLE appears
on the DIC, the system has been
disabled because the sensor is
blocked and cannot detect vehicles
in the blind zone. The sensor may
be blocked by mud, dirt, snow, ice,
slush, or even heavy rainstorms.
This message may also activate
during heavy rain or due to road
spray. The vehicle does not need
service.
See Side Blind Zone Alert (SBZA)
on page 9 64 for more information.
