2.3 Towing hitch installation
Fold out folded page 2-27
Before the installation of the towing hitch take all the protective stoppers off the welded nuts on the towing hitch.
A
Drill holes with a diameter of 14 mm on both the left-hand and right-hand side members (1) at the marked
positions.
If the drilling positions are not marked, both side members must be marked as shown in the illustration.The
illustration shows the left-hand side member. Proceed accordingly for the right-hand side member.
B
Before the installation of the longitudinal supports (4), glue the foam ring (2) over the impact absorber opening (3).
Push the left-hand longitudinal support (4) and the right-hand longitudinal support into the impact absorber
opening (3).
There are three holes on the left-hand longitudinal support (4) in the mounting plate for the impact absorber.
The right-hand longitudinal support also has holes in the mounting plate for the impact absorber.
C
Tighten the two longitudinal supports on the side members by hand using the hexagonal bolts (5) and washers.
D
Mark the hole (7) on the rear bulkhead on the installed right-hand longitudinal support (6). Remove the longitudinal
support and drill a hole with a diameter of 14 mm. Install the longitudinal support again.
coupé only:
Drill a hole (8) with a diameter of 33 mm for the additional wiring harness as shown in the illustration on the
right-hand side next to the passage for the registration plate light.
E
Place the towing hitch (d) against the rear bulkhead. Insert the hexagonal bolts (9) with washers (10). Align the
towing hitch (d) and tighten the hexagonal bolts (9) by hand.
First tighten the bolts on the towing hitch (d), then secure the longitudinal supports (see Figure C).The tightening
torque is 60 Nm.
F
If there are no adjustment bushes (11) for adjusting the height of the bumper in the towing hitch, the
adjustment bushes (11) from the old impact absorbers must be refitted.
Place the holder (12) for the vibration absorber (13) against the assembled towing hitch (d). Secure the holder (12)
with the hexagonal bolts (14), washers (15) and hexagonal nuts (18). Push the vibration absorber (13) into the
holder (12) and secure it with toothed washers (17) and hexagonal nuts (18).
coupé only
Do not install the vibration absorber (13) or its holder. Secure the adjustment bushes (11) with hexagonal bolts (14),
washers (15) and hexagonal nuts (16).
