replenished
The reducing agent is added by the service
center within the context of regular mainte‐
nance. Provided you observe this maintenance
schedule, it is normally necessary to replenish
the fluid once between maintenance appoint‐
ments.
It may be necessary to have the fluid replen‐
ished several times under particular circum‐
stances, for example, if the vehicle is driven in
a particularly sporty style or if it is driven at
high altitudes.The reducing agent must be replenished as
soon as the reserve display appears in the in‐
strument cluster to avoid not being able to re‐
start the engine.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible that reducing agent may also need to be re‐
plenished between regular maintenance ap‐
pointments if it is exposed to temperatures be‐
low + 23 ℉/- 5 ℃. In this case, add reducing
agent only immediately before starting to drive.
The need to replenish it is indicated by the Re‐
serve display in the instrument cluster.
At temperatures below + 12 ℉/- 11 ℃ the fill
level in some cases cannot be measured.
After adding reducing agent, the reserve dis‐
play is displayed only until the fill level can be
measured again.
Replenishing Diesel exhaust fluid
yourself in exceptional cases
You can replenish reducing agent yourself in
exceptional cases, e.g., to get to the service
center.
Avoid contact with Diesel exhaust fluid
Do not come into contact with the reduc‐
ing agent. Otherwise, skin or eye irritations
may result.◀
Handling Diesel exhaust fluid

General information The engine oil consumption is dependent on
the driving style and driving conditions. When
a sporty driving style is used, the engine oil
consumption, for example, is clearly higher.
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
Checking the oil level
electronically
Status display
The concept The oil level is monitored electronically during
driving and shown on the Control Display.
If the 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.

Condition Based Service
CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Detailed information on service requirements,
refer to page 82, can be displayed on the Con‐
trol Display.
Service data in the remote control Information on the required maintenance is
continuously stored in the remote control. Your service center will read out this data and
suggest the right array of service procedures
for your vehicle.
Therefore, hand your service specialist the re‐
mote control with which the vehicle was driven
most recently.Storage periods
Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if necessary,
changing the engine oil and the microfilter/
activated-charcoal filter.
