Power §teer]ng
A frequent necessity in today's traffic,
particularly in crowded city centers is
manoeuvring and parking the car in a
very limited space. Usually, the steering
must be turned several tìmes from lock to
lock while the vehicle is at a standstill or
moving very slowly.
At other times, an ùnexpected emergency
situation may call for an instant change
of direction at high speed if a collision is
to be avoided. If as a result one front
wheel should run off the road on to an
uneven surface, sudden and violent later-
al forces in one direction may be applied
to the steering.
With hydraulic power steering, the driver
will in both cases only feel a slight
additional resistance at the steering
wheel rim, since all h`is movements are
assisted by hydraulic sèrvo action.
This power assistance not only contri-
butes greatly to effortless driving, but
also constitute§ a substantial safety fac-
tor.
If the BMW Coupé is your first car with
hydraulic power steering, please note
that you may need a little time to become
used to its light action when driving the
Car.
Construction:
The housing of the ZF ball and nut poweT
steering mechanism contains the control
#a:::sa,n?8àHSì:ne#yg'i:g:rraasnsdeà3PyT8!Fg
supplied under pressure to operate the
steering from a ZF high pressure vane
type pump driven by V-belt from the
engine. The circuit includes a reservoir
with oi 1 filter.
The design of the power steering ensures
that in the event of a fault in the hydraulic
system or a breakdown (involving towing
the car with a deàd engine) the car can
still be steered manually, although the
effort required at the steering wheel is
then much higher.

checked, and during each maintenance
session (see "CARE AND MAINTEN-
ANCE"). For initial or subsequent filling
of the power steering system, and for
topping up minor fluid losses, use only
the grades of hydraulic fluid specified
under the appropriate headings on page
115.
Every 60000 km (40000 miles), the filter
element should be renewed and correct
operation of the power steering fully
checked. This work and any other atten-
tion needed to the power steering should
only be carried out by an authorized
BMW service station.
