The power steering assists the driver when turning the steering wheel (with the engine running).

The power steering assists the driver by reducing the force needed to turn the steering wheel. The degree of power assistance is adapted electronically, depending on the speed.

If a fault should occur in the servotronic system the power steering will still operate. The degree of power assistance will, however, no longer adapt to different speeds. If the electronic regulating system is not working properly, this is most noticeable when turning the steering wheel at low speeds (for instance when parking) – more effort will be required than usual. The fault should be corrected by a qualified workshop as soon as possible.

The power steering does not function when the engine is switched off. In this case the steering wheel is very hard to turn.

If the steering is held at its turning limit when the car is stationary, this will place an excessive load on the power steering system. In this case, the power steering system will make noises. It will also reduce the idling speed of the engine.

Caution
Do not keep the steering in the full-lock position for longer than 15 seconds when the engine is running – this could cause damage to the power steering system.

Note
• If the power steering should fail at any time or the engine is switched off (for instance when being towed), the car can still be steered. However, more effort will be required to turn the steering wheel.
• If the system is leaking or malfunctioning, please take the car to a qualified workshop as soon as possible.
• The power steering requires a special hydraulic fluid. The fluid reservoir is located at the front of the engine compartment on the left. The correct fluid level in the reservoir is important for the power steering to function properly. The hydraulic fluid level is checked at the Inspection Service.
