With Keyless Ignition is there an Assessory Polition Like with a key to have Power ON ?

[Cosmic Charlie]

Or do you have to start the truck then shut it off and it will retain power for the programed 10 minutes time ?

Push the start button without foot on brake.  

[Makito]

Press and hold the start button with foot off the brake. Might take 10 seconds

[gemarsh]

Should be able to just momentarily push button (w/o pressing brake pedal) and get acc power. Keyless button will have a amber light. Push and hold button for so long and everything wakes up, with a green light.

I've look thru the owner manual and found ZIP regarding this - was this discovered by trial & error ?

With foot off brake momentary push of start switch puts you in accessory mode. With foot off brake 5 second hold of start switch puts you in service mode.

LOL Just 5 minutes active

 

ACC/ACCESSORY (Amber Indicator Light) :
This mode allows some electrical accessories
to be used when the engine is off.

 

With the ignition off, pressing the ENGINE
START/STOP button one time without the
brake pedal applied will place the ignition
system in ACC/ACCESSORY.

The ignition will switch from ACC/
ACCESSORY to off after five minutes to
prevent battery rundown.

Salesman's job is to give the new customer a run through of the new vehicle.  My salesman rode with me to the gas station explained all the features and put in whatever brand on gas I wanted, even premium (had company credit card) fuel in my 6.2L.

You got a good one then.  They are not all like that.

I have no problem getting the Acc. on for 5 min. without starting the motor but is there anyway to extend the acc. time on more than the 5 or 10 min. allotted? It would be nice to listen to some Sirius XM while detailing my interior!!!

I was trying this yesterday as I was waiting in the truck for wife to finish picking up some stuff. Something not mentioned is you need to have the keys in the vehicle. If it senses no key it will not go into this mode. Guess that is a good thing.
