I tow a 2010 SRX 2 wheel drive with all 4 down. Per the dealer, they recommend you turn vehicle off in park and remove boot, press the release button then shift to netrual. Asked about removing fuses and he replied,"for what reason.". Followed his instructions with no problems. Nothing in the 2010 owners manual about removing fuses. Instead of removing the boot each time, I use a sharp object to press the release button.
