In areas exposed to particularly high stresses (dampness, scouring), additional safety precautions may however
be required.
The following measures are recommended depending on the application.
Protect repair area using:
Heat-shrinkable tube
Corrugated tube
Wrapping with fabric tape
Spaghetti insulation

Risk of accident
from vehicle starting off during starting operation (e.g. when testing compression pressure) as a result of gear
engaged or when engine running, or vehicles with automatic transmission as a result of selector lever position
"P" or "N" not engaged (exception: some vehicles do not have a selector lever position "P" ).
Injury hazard
Severe injuries may be caused by unshielded rotating parts in the area of the running engine.
The heat produced by the running engine can result in severe burns if contact is made with individual,
unshielded parts.
Procedural guidelines and safety precautions
As a general rule, carry out work on the running engine only if this is absolutely necessary.
Before starting the engine, apply parking brake .
On models with manual transmission move gearshift lever into Neutral position .
On vehicles with automatic transmission move selector lever into position "P" or "N" (exception:
some vehicles do not have a selector lever position "P" ).
On models which do not have selector lever position "P", secure selector lever to prevent it from
being operated unintentionally .
Wear closed and close-fitting work clothes.
All items of jewelry like chains or rings must be taken off.
Restrain long hair by wearing an appropriate head cover.
Before commencing any work on the running engine, familiarize yourself with the location of potentially
hot parts.
When carrying out work when starting the engine or when engine is running do not touch any hot and
rotating parts .
First aid measures in the event of burns
Do not rub the skin areas affected; flush with plenty of cold water and cover skin with sterile bandages.
Consult a doctor without delay.
RISK OF INJURY CAUSED BY DRILLING GAS-FILLED ASSEMBLIES OR COMPONENTS (NONCOMBUSTIBLE GASES)
- AS00.00-Z-0006-01A
Wear safety glasses and a face mask.
Risk of injury when drilling
There is an increased risk of injury to the skin and eyes when drilling gas-filled assemblies due to shavings
being thrown out. The shavings are picked up by the escaping gases and accelerated to a greater or lesser extent
depending on the pressure. The extent of injuries increases as the pressure increases. The pressures involved

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.

Run in gently, but briskly.
Avoid high load, high rpm and high speed.
Automatic transmissions: do not use kick-down and do not brake the vehicle by shifting down manually.
After 1 500 km
Gradually bring the vehicle up to its full road and engine speeds.
