DESCRIPTION AND OPERATIONDESCRIPTION AND OPERATION OF
DIRECTIONAL SIGNAL LEVERhigh to low beam or vice versa. On all
19M) Rallye
cars, when switching from low to high beam posi-
tion, with the fog lamp instrument panel switch ON
The direction signal switch lever is a multi- purpose
lever controlling direction signals, passing signal and
headlight high and low beams. See Figure
3E-2.The dire&M signal lever is provided with a two-
step mechanism for operation of headlight high and
low beams, and passing signal (not in N.J.). With
headlights off, moving the lever repeatedly towards
steering wheel flashes headlights as a passing signal.
With headlights on, moving the lever repeatedly to-
wards steering wheel up to first stop also flashes
passing signal regardless whether or not the direction
signals are switched on. When the lever is moved up
to the second stop, the headlights are changed from

and ignition switch in RUN position, the fog lights
are automatically switched off. Direction signals
work in the normal manner; pushing the lever up for
right turn signal and pulling the lever down for left
turn signal.
DESCRIPTION AND OPERATION OF HORN
The horn button is located in the center part of the
steering wheel. The horn is actuated by pushing on
the ends of the spokes for the Opel 1900 - Manta and
by pushing on the center horn button on 57R, 57L,
and GT. The button is provided with a plug connec-
tion for each springloaded plunger. See Figure

3E-3 Horn Button Connections (Opel 1900Manta)DESCRIPTION OF STEERING COLUMN
ASSEMBLYThe steering column mast jacket is provided with a
tube-frame section
.(See B of Figure 3E-4) with
bulges which compresses or folds itself, if a suffi-
ciently large energy is exerted to one or other end of
the steering mast jacket assembly. This tube-frame
section absorbs most of the energy. The steering col-
umn consists of two parts, the upper and lower mast
jacket assembly and’the steering shaft. The
upp,ersteering mast is firmly connected to the tube while
the lower steering mast is clearance-free attached to
the tube by means of injected plastic (See Figure
3E-4). Consequently, the steering mast withstands
all torsional stresses.
As soon as the primary energy becomes effective, the
plastic pins (c) shear off and the steering shaft com-
presses. Thereafter the steering mast jacket is partly
compressed.
A slide-off base is welded to the steering mast jacket.
It is provided with two (2) slots for the respective
attaching bolts. A metal piece (See Figure 3E-4) is
located in each slot which is attached to the slide-off
base with injected plastic. The open sides of the slots
face the driver so that the primary energy cannotpush the steering mast jacket assembly into the pas-
senger compartment. The secondary energy caused
by the driver can on the other hand effect a shearing
of the plastic pins and loosening of the slide-off base
so that it moves downwards. Thereby the steering
mast jacket assembly is compressed further and ab-
sorbs the impact energy to a large extent.
The energy absorbing steering is not more suscepti-
ble to damage than a standard steering. However, the
steering mast jacket assembly, especially if removed,
has in contrast with the standard steering to be given
a difierent treatment.

3E-4 Energy Absorbing Steering Column
The energy absorbing steering column must by no
means be subject to impacts or blows. A sharp blow
onto the exposed steering shaft ends, leaning onto
steering column or dropping may loosen or even
shear off the plastic attachments which bring about
rigidity of assembly. In spite of a steering column
damaged in this way the operating function of the
steering is retained due to the lateral flattenings on
steering shaft tube and lower steering shaft. How-
ever, after a short period of operation rattling noises
will be noticeable so that the steering column has to
be replaced. For pulling steering wheel off steering
column use appropriate special tool. Therefore, it is
of importance that the instructions for removal and
installation as well as disassembly and assembly are
Strictly adhered to.
