Somewhere recently I read that on the Chevys another change is it increases the number of times the turn signal flashes from 3 to 6, when you just tap it. Tested mine the other day and sure enough that is true.
I always seem to get dumped on when I suggest people should take a couple of hours and read their owner manuals; who knows what else is in there that they don't know (but SHOULD)?
Here's the response I just got on the Traverse Forum when making the same suggestion to a guy who couldn't figure out how to get his dome lights to turn on when his door opened:
Yeah, I could spend "a couple hours" reading the owner's manual or I could spend 30 seconds searching the internet. It took me less time to get the answer from here than it would have taken me to walk out to the car and get the manual. Thanks for the suggestion though.
From my Silverado Owner's Manual:
Raise or lower the lever for less than one second
until the arrow starts to flash to signal a lane change.
This causes the turn signals to automatically flash
three times. It will flash six times if tow-haul mode is
Holding the turn signal lever for more than
one second will cause the turn signals to flash until
you release the lever.
