conditions are met:
the replenished quantity is at least 1 l
after replenishing the oil, the car must be driven a distance of at least 5 km under normal driving
conditions at an oil temperature of at least 60°C
There are instances, however, in which the readout of the remaining distance nevertheless appears implausible
after replenishing oil; according to the display, no bonus or only a small bonus has been issued. This is caused
by the fact that the remaining distance is always only displayed within a range from 15 000 km up to 30 000 km
(or 20 000 km up to 40 000 km in the case of engine 668), but internally the system calculates with the actual
values which may also be beyond this range. These internal values can only be displayed with the HHT.
horizontal (x) axis represents the service interval and the vertical (y) axis is the remaining distance in each case
in km.
The readout of ASSYST in the instrument cluster always moves within the light range.
The remaining distance calculated internally may also, however, be within the two dark ranges. These internal
values can only be displayed with the HHT.
All examples relate to gasoline engines fitted with an oil sensor.
Example 1 :
Sufficient oil was added during the oil change. This means that the starting distance is 15 000 km.
After 10 000 km oil is topped up under normal driving conditions (a). The bonus (B1) is issued and displayed.
What this means is that when the remaining distance is retrieved, a greater remaining distance is displayed.
(Provided the aforementioned conditions for detecting the oil replenishment are met.)
Oil is topped up again after a further 5 000 km (b). In this case also a bonus (B2) is issued and displayed.
If, after this, no further oil is topped up and the car continues to be driven in the same manner, a service interval
of about 24 000 km is thus achieved.
In this example, the curve moves at all points within the light range of the chart; consequently, all the oil
replenishments are displayed by increasing the remaining distance.

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
