I have 2007 Lexus ES350 and today my VSC, TRAC, Engine service and a red exclamation mark light all came together, how do I turn them off

 

Read the codes, fix the problem clear the codes. Do you have a code reader? You can't do much of anything until you find out what the computer is trying to tell you.

 

It's probably safe to drive for a while without the VSC system or traction control system working......just keep in mind that you won't have any of the electronics working to keep you out of trouble if you get too aggressive. But you'll probably want to get them fixed before winter, and slick roads, come....and definitely get the engine-codes looked at, as the car will not pass a state inspection (if applicable) with them on.

Keep in mind that, with computer codes, a technician should NOT just mindlessly replace a part, as a knee-jerk reaction, just because the code says (oxygen sensor) or (throttle-position sensor) or (mass-air-flow sensor), or something else like that. The correct way to do it is to consult the Service Manual for the vehicle, look up the code, and then do an exact step-by-step procedure, explained in the manual, to isolate the problem and determine exactly what it is. Otherwise, you just might (?) end up spending money for nothing by having irrelevant parts replaced. That service manual is written by the engineers who actually designed the vehicle. Good reputable repair shops do it that way...fly-by-night places don't.

 

Doesn't anyone read the owner's manual anymore? I know that the manuals may be getting thicker but with PDF versions available online, they are also easier than ever to search.

Look up in the owner's manual what the various warning lights mean; make an appointment for service, explaining what problems you have; and let the service technician clear the code and turn off the lights. Don't just go and turn off the lights yourself; the lights came on for a reason, so resolve the problem before turning off the warning lights.

 

If anything, that's a understatement. And seems like a large part of it is hundreds of pages of either child-safety procedures or how to read / program / adjust all of the electronic systems.
