Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is set. The
vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as you step on the brake or accelera‐
tor pedal, the engine is automatically coupled
again.
Hints
Coasting is a component of the ECO PRO, re‐
fer to page 175, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A proactively driving style helps the driver to
use the function as often as possible and sup‐
ports the fuel-conserving effect of coasting.
Safety mode
The function is not available under one of the
following conditions.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In ECO PRO mode, this function is available in
a speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if
the following conditions are met:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.
The driving status Coast can be influenced
with the shift paddles.

Engine oilVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
General information
The engine oil consumption is dependent on
the driving style and driving conditions.
The engine oil consumption can increase in
case of, for example:▷Sporty driving.▷Break-in the engine.▷Idling of the engine.▷Usage of non-approved engine oil grades.
Therefore, regularly check the engine oil level
after refueling.
The vehicle is equipped with electronic oil
measurement.
The electronic oil measurement has two meas‐
uring principles:
▷Status display▷Detailed measurement
Electronic oil measurement
Status display
The concept
The engine oil level is monitored electronically
while driving and shown on the Control Dis‐
play.
If the engine oil level reaches the minimum
level, a check control message is displayed.
Requirements
A current measured value is available after ap‐
prox. 30 minutes of driving. During a shorter
trip, the status of the last, sufficiently long trip
is displayed.
With frequent short-distance trips, regularly
perform a detailed measurement.
Displaying the engine oil level
On the Control Display:1."Vehicle info"2."Vehicle status"3. "Engine oil level"
Engine oil level display messages
Different messages appear on the display de‐
pending on the engine oil level. Pay attention
to these messages.
If the engine oil level is too low, within the next
125 miles/200 km Add engine oil, refer to
page 201.
Engine oil level too low
Add engine oil immediately; otherwise,
an insufficient amount of engine oil could re‐
sult in engine damage.◀
Take care not to add too much engine oil. Too much engine oil
Have the vehicle checked immediately;
otherwise, surplus engine oil can lead to en‐
gine damage.◀
