1. Disconnect the high voltage wire at the ignition coil.
2. Rotate the steering wheel in both directions, including the starter for 15-20 seconds.
3. Repeat the last operation 5-6 times, watching the fluid level in the hydraulic booster reservoir. The level should not change when turning the steering wheel.
4. Connect the wire and start the engine, at idle turn the steering wheel in both directions until it stops.
5. The change in level when turning the steering wheel should not exceed 5mm, and the liquid should not be homogeneous (no small bubbles). If the level changes more strongly, or if the level rises sharply after turning off the engine, there is air in the hydraulic booster.
6. Add liquid and close the tank with a stopper.
7. Install the spare wheel and secure with bolts, tightening them slightly.
8. Lower the wheel. Torque tighten the wheel bolts in diagonal sequence.
