There are no indicators that a burn is about to start or is in progress. It's fairly apparent when its happening; loud fan noise, increased engine temp on the offoad page. Once a burn starts it cannot be interrupted even if you turn off the vehicle. I'm looking forward to more Euro 6 compliant vehicles on Australian roads so its not just Grenadier owners getting filthy looks.
I would like to see the control logic changed so the driver gets a pre-burn advisory light and can defer the burn for a set period via a cancel button if the burn should not proceed at that time. Like it's midnight and you've just pulled into your garage, or you're traversing long dry grass and the extra heat under the vehicle is a fire risk.
Does Offroad Mode affect DPF burn operation?
