Chevrolet Silverado: Warning Lights, Gauges, and Indicators / Lane Departure Warning (LDW) Light (2500/3500 Series)

This light is green if LDW is on and ready to operate.

If equipped, the Hill Descent Control light comes on when the system is ready
for use. When the light flashes, the system is active.

After the vehicle is started, this light turns off and stays off if LKA has not
been turned on or is unavailable.

Other information:
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 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...
Warning
Leaving children in a vehicle with the ignition key is dangerous and children
or others could be seriously injured or killed. They could operate the power windows
or other controls or make the vehicle move. The windows will function with the keys
in the ignition, and children or others could be caught in the path of a closing
window...

If equipped, there is a small convex mirror built into the upper and outer corner
of the driver outside mirror. It can show objects that may be in the vehicle's blind
zone.
Driving with the Blind Spot Mirror

Actual Mirror View
When the approaching vehicle is a long distance away, the image in the main
mirror is small and near the inboard edge of the mirror.
As the vehicle gets closer, the image in the main mirror gets larger and
moves outboard.
As the vehicle enters the blind zone, the image transitions from the main
mirror to the blind spot mirror.
When the vehicle is in the blind zone, the image only appears in the blind
spot mirror.
