Lane Departure Warning (LDW)
For vehicles with LDW, it is intended to help avoid lane
change collisions. It provides a warning if the vehicle is
crossing a lane without using a turn signal. LDW uses a
camera to detect the lane markings. It only operates at
speeds of 56 km (35 mph) or greater.
The warning symbol
@
, located in the instrument panel
cluster, appears green if a lane marking is detected.
It changes to amber, flashes, and sounds three chimes
if the vehicle crosses a detected land marking and the
turn signal is not on.
To turn LDW on and off, press the LDW button, located
by the exterior headlamp control.
See Lane Departure Warning (LDW) on page 3‑38 for
more information.
Side Blind Zone Alert (SBZA)
For vehicles with this feature, it may alert you to
vehicles located in your side blind zone. When the
system detects a vehicle in the side blind zone, an
SBZA display will light up in the corresponding outside
side mirror indicating that it may not be safe to change
lanes.
The system is enabled at every vehicle startup. It can
be disabled through the Driver Information Center (DIC).
If the message SIDE BLIND ZONE SYS.
UNAVAILABLE appears on the DIC, the system has
been disabled because the sensor is blocked and
cannot detect vehicles in the blind zone. The sensors,
located behind the rear quarter panels, may be blocked
by mud, dirt, snow, ice, slush, or even heavy
rainstorms. The vehicle does not need service.
See Side Blind Zone Alert (SBZA) on page 3‑34 for
more information.
