Mercedes-Benz ML320. Manual — part 603

These maintenance documents contain instructions relating to carrying out maintenance and repair operations
on Mercedes-Benz passenger cars. They are intended for the exclusive use of workshops affiliated to the
Mercedes-Benz Organization.

The instructions form the basis for proper and competent service and maintenance.

The nature in which the operations are described is based on the training standard of a fitter who has completed
vocational training and has good knowledge of our products. This level of knowledge is essential for carrying
out the described work.

The continuous further development and improvement of our vehicles may lead to deviations between the
actual technical status of the vehicles and the operation descriptions.

DaimlerChrysler AG reserves the right to make alterations and modifications at any time and without prior
notice.

If there are any open questions relating to repair procedures, please take up the matter with the competent
contact person in the relevant national organization (for DCVD refer to valid Service Information Group 99).
Additional information about the breakdown and structure of the work descriptions and the meaning of the
symbols (Logos) can be found in the Workshop Information System WIS.

Each described maintenance operation has a number (operation item) which is stated in the head line. The
operation item in the maintenance manual is identical with that on the SERVICE SHEET for the Active Service
System (ASSYST), enabling the appropriate texts and data to be found straight away if required when
performing maintenance jobs.

Maintenance operations which are not described have no number (operation item) on the SERVICE SHEET.

The group numbers familiar from the workshop literature are used for the first two digits of the 4-digit operation
item numbers. This ensures the assignment of each maintenance operation to the group.

These instructions are to be read carefully and complied with in full In order to rule out any risk of personal
injury, to avoid impairing the reliability and safety of the vehicle, and to prevent damage to the vehicle as a
result of work improperly carried out.

It is therefore not possible for DaimlerChrysler AG to evaluate in the last consequence every situation which
might present a risk of injury for the operative. It is therefore an urgent necessity that everyone who carries out
repair work on Mercedes-Benz passenger cars by applying his professional knowledge satisfies himself that his
own safety is not at risk and that the vehicle will not suffer any negative effects, in particular of a safety
engineering nature, as a result of the repair procedure adopted.

It is therefore expressly pointed out that all work for the operations described must be carried out in compliance
with valid directives and instructions from the responsible local authorities and those relating to health, work
safety and environmental protection.

ADDITIONAL DESIGNATION FOR MODELS AND COMPONENTS - AP00.20-P-0000-03A

Models and components, in addition to their 3 to 6-figure designation (e.g. 124 or 124.028), may have different
versions, dates and work procedures. These differences are indicated by the following additional designations:

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.
