Vehicle features and options
Safety information
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features that are not necessarily
available in your vehicle, for instance, due to the
selected options or country versions. This also
applies to safety-related functions and systems.
When using these functions and systems, the
applicable laws and regulations must be ob‐
served.
NOTICE
An engine oil level that is too low causes en‐
gine damage. There is a risk of damage to
property. Immediately add engine oil.
NOTICE
Too much engine oil can damage the engine or
the catalytic converter. There is a risk of dam‐
age to property. Do not add too much engine
oil. When too much engine oil is added, have
the engine oil level corrected by a dealer’s serv‐
ice center or another qualified service center or
repair shop.
General information
The engine oil consumption is dependent on
your driving style and driving conditions. When a
sporty driving style is used, the engine oil con‐
sumption, for instance is clearly higher.
Therefore, regularly check the engine oil level af‐
ter refueling by taking a detailed measurement.
Electronic oil measurement
The engine oil consumption can increase in the
following situations, for instance:
General information
The electronic oil measurement has two measur‐
ing principles:
▷ Sporty driving style.
▷ Break-in of the engine.
▷ Idling of the engine.
▷ Monitoring.
▷ With use of engine oil types that are classified
as not suitable.
▷ Detailed measurement.
When making frequent short-distance trips or
using a dynamic driving style, for instance when
taking curves aggressively, regularly perform a
detailed measurement.
Different Check Control messages appear on the
Control Display depending on the engine oil
level.
Monitoring
Concept
The engine oil level is monitored electronically
while driving and can be shown on the Control
Display.
