When does it happen?
Does it happen all the time?
Have you had it looked at?
(It stores a fault when that warning is on)
It's winter in New York and it seems like almost every start up it does this after acouple of minutes, I'm planning on getting it checked out the next oil change since it's not a crucial part of the car. A restart of the engine resets it but it pops up again ?
From what I can tell from the manual (you know, the manual that the screen is telling you to check), it has to do with the Driver Assistant Indicators:
Driver assist system indicator
(if so equipped)
This indicator shows the status of the
following systems.
. Lane Departure Warning (LDW)
. Lane Departure Prevention (LDP)
. Blind Spot Warning (BSW)
. Blind Spot Intervention
2-28 Instruments and controls
TM
(BSI)
. Distance Control Assist (DCA)
. Forward emergency braking
. Predictive forward collision warning
For more details, see “Lane Departure
Warning (LDW) system/Lane Departure
Prevention (LDP) system” (P.5-30), “Blind
Spot Warning (BSW) system/Blind Spot
Intervention
TM
(BSI) system” (P.5-37), “Dis-
tance Control Assist (DCA) system” (P.579),
“Forward emergency braking system”
(P.5-89) and “Predictive forward collision
warning system” (P.5-94).
The figure and color of this indicator will
change depending on the conditions of the
above systems. (In each section, the name
of this indicator is referred to as, “driver
assist system lane indicator”, “driver
assist system blind spot indicator” or
“driver assist system forward indicator”
depending on the systems.)
Its hard to tell for sure, because the symbols on page 2-23 are fairly small, but I believe that is the warning you are seeing.

There should be a fault stored in the system that will keep for maybe 40 key cycles (conservatively).
If it goes away on a subsequent restart I would think that something in the diagnostic self check logic is seeing an error at the time of first inspection that it considers wrong and shutting down instead of allowing to use the safety tech systems while it is unsure of its status. There is no repeat testing done on the system integrity if a fault is stored (to the best of my knowledge), the only cure is a forced retest.
Rear sonar and side radar faults are nothing new, and not limited to this brand but when it could potentially effect the functionality of the Safety Shield system so I think its error tolerance has to be very low. I have heard of some brands having an issue when started next to a wall or partition made of a certain material that effects the sensors self check, but I have never seen one first hand.
A quick note, there are three separate subsystems that control detection of moving objects in the rear of the car. (rear proximity sonar, rear radar modules, and an software program for the MOD function) The one in this issue seems to be within the rear radar unit(s).
Did this happen on start of the car or while driving? I've had the rear radar and front camera go off-line once in heavy rain while I was creeping along at 3 mph. Thankfully it hasn't happened since I restarted the car. The timing of the malfunction seems pretty random.
Are you parking in a garage? I know in my garage, it is a tight fit and would probably drive any proximity sensors bonkers.
This happens when the car starts and also when driving I will hear a chime if my music isn't up and see the malfunction. I park it outside on a quiet residential street.
