It is risky to bleed by manually pumping the brake pedal, as the master cylinder piston travel will be much further than for normal braking. This can result in piston seal damage and an ineffective braking action. I learned this the hard way. Popular Mechanics magazine had an article about this, many years ago.
As such, I would recommend using a Motive Bleeder with an adapter to fit the Lexus. No manual pumping of the brake pedal is required.
I believe the sequence is:
Rear left, rear right, front right, and front left. Jack up the car and begin with the rear left wheel, then work your way through the other wheels.
Also, I don't know if the ABS module needs to be cycled, as it does in many late-model vehicles.
