Transmission Mode Indicator - A/T: Description and Operation
The propeller shaft and wheels are free even when the transmission shift lever is set to P as long as the transfer shift lever is in Neutral position.
The A/T.P. indicator light lights up to warn the drive that the propeller shaft and wheels are not locked.
If the A/A/T.P. indicator light goes on, the transfer shift lever should be shifted out of N position.
