AE1M

You say yours was delivered to GM to Canada and the headlight switch will rotate to OFF when NOT in Park? If so, it does not operate as the manual states on page 178

Mine was purchased in Toronto. I guarantee that my truck was initially sold in Canada and the headlight switch operates exactly as the owners manual says. It will not rotate to the off position unless the trunk is in PARK. I can also guarantee the dealer confirmed E85 is not recommended and therefor the yellow sticker is not there. All exactly as the owners manual says. Bob

Friend, Where people get that info is from the Owners Manual. Vehicles sold in CA must not be able to turn the headlights off while the vehicle is moving, so the switch is designed NOT to rotate to the off position in that case. Here is cut/paste from owners manual P 178 "For vehicles first sold in Canada, off will only work when the vehicle is in P (Park)." I never said E85 was illegal, what I said is that the trucks GM exports to CA for some reason cannot use E85. Here is another cut/paste from the owners manual P 324 and is why those trucks are not labelled for E85. (they dont have the yellow E85 badge). Engine must be tuned differently I suppose. "E85 or FlexFuel should meet ASTM Specification D 5798 or CAN/ CGSB–3.512 in Canada. Do not use the fuel if the ethanol content is greater than 85%. Fuel mixtures that do not meet ASTM or CGSB specifications can affect driveability and could cause the malfunction indicator lamp to come on." "Vehicles that have a FlexFuel badge and a yellow fuel cap can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85). See E85 or FlexFuel ." I look forward to your apology. Bob

Correct, this is one of the differences in trucks initially sold into Canada. The round switch to turn OFF the headlights will not rotate to the OFF position while the truck is moving. Otherwise it will rotate to OFF. Canadian safety law. Also, Canadian sold trucks cannot use E85, My 2016 High Country is the same way.

Love it except in tight parking lots......

I have the Range installed and also have come concern about the AFM lifters not getting exercised occasionally. So, I leave the Range installed most of the time, but if I take a long trip on the highway, I will pull it to both exercise the mechanism and to get the better mileage.

The passenger side only does swing out when the door is opened. It does not rotate back when the switch on the end is kicked as it should. The driver’s side works fine. I am thinking it must be the switch.

Thanks, got it off, now just have to figure out how to free the connector. My board on pass sided doesnt articulate, going to try ordering a new end-cap with switch. Bob

2016 High Country My passenger side articulated running boards will not move backwards when the kick switch is pushed. Anyone know how to remove the end cap to check the switch? I tried prying but met with more resistance than I was comfortable with to continue prying. Bob

Averaging 27.1 MPG in a Silverado. I am throwing the BS flag unless all your driving is downhill.

Maybe you need to rotate the air in your tires, it get's pretty smelly if you don't.

Interesting. Did you try just disabling on the phone temporarily instead (“Hey SIRI, stop Bluetooth”)?

Sorry I didnt see your reply, I have the Extang Solid Fold 2 and their light. Nice thing is that it can be removed for a flashlight also. I decided to mount on the side instead of on the tonneau. I keep the charger in the truck, every few months i'll just bring it in to make sure it's charged. Has 3 brightness settings. Bob

I have found this topic of disabling AFM quite odd. I am a fairly new (8 months) owner of a 2016 High Country. Sweet f’ing ride, none of the vibrations issues discussed. On a recent long distance drive (over 1000 miles total) I achieved a tad over 23 MPG (actual measured) and saw the display switch to 4 cyl often while cruising, Engineers at GM (I assume) worked hard to create this feature, why disable it? In late summer in 2018 after buying this used truck, I had no issue towing 6500lb boat, launching etc.... Why would I spend 100s and risk screwing up what was designed into the truck to improve fuel effiency etc? My truck may be different as it was sold in Canada which has a few differences like no E85 etc... Bob

On my 2016, I see up to 1.5A on the USB port charging iphone.
