7 Modifications to the basic vehicle
7.2 Bodyshell/body
7.2.1 General information on the bodyshell/
body
Modifications must not have a negative effect on the
function or strength of vehicle equipment or controls or
on the strength of load-bearing parts.
In the case of modified vehicles, it is not permissible to
make modifications that affect the function or freedom
of movement of vehicle parts (e.g. during maintenance
and inspection work) or accessibility of these parts.
Observe the following:
• All modifications must be presented in advance in
the form of drawings and calculations and certified
by the vehicle manufacturer.
• Changes to the wheelbase are not permitted.
• The maximum permissible axle loads must not be
exceeded.
• On no account should any modifications (such as
drilling or welding) be carried out on the support
structure from the front through to the rear of the
B-pillar.
• Modifications to the windshield and windshield
frame, and to the A-pillar and B-pillar, are not per-
missible.
• Holes on the longitudinal frame member are the
result of the production process and are not suit-
able for securing equipment, as there is otherwise a
risk of damage to the frame.
• It is not permissible to make cuts in the C or D-pil-
lar (rear portal), including the associated roof bows.
• Modification of vehicles with window airbag is not
permissible in the roof area of the B-pillar.
• Partitions may be totally or partially removed, see
chapter 7.2.2 “Partition” (
e
Page 67).
• The clearances for the fuel filler neck and for
the tank and fuel lines must be maintained, see
7.3.1 “Fuel system” (
e
Page 71).
• Avoid sharp-edged corners.
• Trailer connections must be checked for correct
operation.
• If a trailer hitch is installed, the necessary rein-
forcements must be present (
e
Page 90).
• The seat mounting consoles of the 1st and 2nd
rear seat row as well as the standard anchoring
lugs and their mounting points must be used with
priority when retrofitting attachments in the interior
compartment.
• Brackets (plug welds) must be used to attach
additional equipment to the longitudinal and cross
members. These require approval.
• The function of the tire pressure monitoring sys-
tem (TPMS) must not be impaired by modifications
made in the direct proximity of the antennas and
wheels.

nel.

in chapter 4.7 “Threaded and welded connections”
(
