Chevrolet Silverado: Warning Lights, Gauges, and Indicators / Lane Keep Assist (LKA) Light (1500 Series)

After the vehicle is started, this light turns off and stays off if LKA has not
been turned on or is unavailable.
If equipped, this light is white if LKA is turned on, but not ready to assist.
This light is green if LKA is turned on and is ready to assist.
LKA may assist by gently turning the steering wheel if the vehicle approaches
a detected lane marking. The LKA light is amber when assisting.
This light flashes amber as a Lane Departure Warning (LDW) alert, to indicate
that the lane marking has been crossed.
LKA will not assist or alert if the turn signal is active in the direction of
lane departure, or if LKA detects that you are accelerating, braking, or actively
steering.
See Lane Keep Assist (LKA) (1500 Series).
This light is green if LDW is on and ready to operate.
This light changes to amber and flashes to indicate that the lane marking has
been crossed without using a turn signal in that direction...
If equipped, this indicator will display green when a vehicle is detected ahead
and amber when you are following a vehicle ahead much too closely.
See Forward Collision Alert (FCA) System...
Other information:
Warning
Sitting in a reclined position when the vehicle is in motion can be dangerous.
Even when buckled up, the seat belts cannot do their job.
The shoulder belt will not be against your body. Instead, it will be in
front of you. In a crash, you could go into it, receiving neck or other injuries...
The Antilock Brake System (ABS) helps prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the vehicle is first driven.
A momentary motor or clicking noise may be heard while this test is going on,
and the brake pedal may move slightly...
