For these vehicles the service sheet for the Active Service System (ASSYST) and the maintenance manual
volume 4 apply.
With the ASSYST service sheet the previous distinction between care service and maintenance service no
longer applies. Instead, the service category A (minor service) and service category B (major service) have been
introduced.
The service scopes for each model series can be seen in the respective valid service sheet.
The order no. is stated on the particular SERVICE SHEET.
On manual transmissions, automatic transmissions, transfer cases, front axles and rear axles the service item
"Check fluid level" has been replaced by an inspection of all visible parts for leaks.
In view of the fact that these components are not oil consumers, as is the case for the engine, a loss of oil can
occur only to the outside.
If any leaks are present, the procedure, as before, is to determine the cause and to rectify it subject to a separate
repair order.
The service operations carried out should be documented in the boxes in front of the operation titles. It is
essential to ensure that the specified service operations are carried out in full.
An indication is given in the boxes after the operation titles of which service operations should be carried out
for service category A (minor service) or service category B (major service). Enter a cross behind these boxes to
identify any items which are not in proper order when the vehicle is received.
Additional operations should be defined by the service adviser in agreement with the customer and an indication
should be made on the service sheet whether these additional operations are to be carried out.
