If you don’t want to be a slave to watering (by making sure your lawn gets an inch a week to keep lush), then I suggest just keeping it alive.
When your lawn looks like toast it has gone dormant. To keep it alive but NOT green and lush you can give it a quarter to a third of an inch of water every 2 to 4 weeks, and limit the traffic on your lawn.
Your lawn is in a weakened state and more susceptible to weeds but you can feel good that you’re not wasting water just to have your lawn look good. I know, you’ve worked hard on that lawn. If you must, then water early in the morning and have an inground watering system to lessen transpiration (i.e. your grass gets the water rather than the atmosphere).
