188Power steeringThe 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 power steering does not work if the engine is 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. Turning the steering
wheel to its limit places a load on the system, which causes noise. It will also
reduce the idling speed of the engine.
Caution
When the engine is running, do not turn the steering wheel to its limit for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering.
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 quali-
fied 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 ⇒ page 289. The
correct fluid level in the reservoir is important for the power steering to func-
tion properly. The hydraulic fluid level is checked at the Inspection Service.
ServotronicThe servotronic system electronically adjusts the degree of
power assistanceIn cars equipped with servotronic power steering the degree of power assist-
ance ⇒page 188 is adjusted electronically according to road 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.

Te c h n i c a l D a t aChecking fluid levelsFrom time to time, the levels of the different fluids in the
vehicle must be checked. Never fill with incorrect fluids,
otherwise serious damage to the engine may be caused.Fig. 233 Diagram for the location of the various elements
