TESTED ON: 2007 IS250 Sports with enhancement pack

SUCCESFUL/FAIL: Success

LEVEL OF DIFFICULTY: medium (requires fancy footwork!)

INTRODUCTION

As we all know, disabling traction control on the IS (by hitting the button twice) is only a temporary disable. As soon as the car detects serious slip, it kicks back in and you lose all that lovely power at the back wheels. Lexus considers this a feature, as you should only ever need to temporarily disable traction control in unique situations, like trying to get out of snow or something. To the best of my knowledge, it's not possible to permamently disable traction control, but it is possible to completely disable it for the duration of a drive (ie: between starting the car and turning it off again).

STEPS

1. Start the car with the park brake on

2. Apply foot brake twice, keeping the foot brake down on the second push

3. Apply park brake twice, leaving it down on the second push

4. Skid light on the dash will illuminate if successful

If it doesn't work the first time, switch the car off and start again at step 1.
