NOTICE
Potential damage to vehicle from slipping off.
– The dimensions of the vehicle support plates and their
spindles must be sufficient to ensure that the load that
is imparted centrally between the outer edge and centre
of the vehicle support plates can be supported. If the di‐
mensions are not sufficient, different vehicle support plates
must be used that meet this requirement.
Note
Not every lifting platform is suitable for the removal of high-volt‐
age battery. Ensure that there is sufficient clearance. When
lifting, ensure that there is sufficient clearance -a- around the
high-voltage battery so that it can be placed on the scissor-type
assembly platform -VAS 6131B-.
– Swivel lifting platform arm with vehicle support plate -1- up
to frame of high-voltage battery -2-. Then swivel back lifting
platform arm with vehicle support plate -1- far enough -a-
to allow for lowering high-voltage battery -2- in the following
step.
– Remove front underbody cladding ⇒ General body repairs,

installing front underbody cladding.
– Detach front right wheel housing liners in area of threaded
connection of high-voltage battery ⇒ General body repairs,
exterior; Rep. gr. 66; Wheel housing liner; Removing and
installing front wheel housing liner.
– Remove side underbody cladding ⇒ General body repairs,
