This procedure is only required if hydraulic system components have been disconnected or if air has entered the system as a result of a leak.
1. Remove the tank cap and bring the liquid level to the maximum mark. The type of fluid is specified in Section Schedule of ongoing maintenance at the beginning of this guide.
2. Slowly move the steering mechanism from one end position to another several times (engine off), to remove air from it, then add fluid to the reservoir. Repeat this procedure until the fluid level in the tank no longer drops.
3. Start the engine. Move the steering gear slowly from one end to the other again to remove any remaining air. Repeat this procedure until no more bubbles appear in the reservoir.
4. If an abnormal noise is heard in the hydraulic pipes when turning the steering wheel, there is still air in the system. Check this by turning the wheels to "directly" and turning off the engine. If the liquid level in the tank rises, further pumping is necessary.
5. At the end of pumping, stop the engine, let the system cool down and make sure that the fluid level is at the maximum tank mark. If necessary, add fluid to the reservoir.
