lead to increased wear and damage to the
major assemblies or the vehicle.
A qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, will reset the
ASSYST PLUS service interval display after
the service work has been carried out. You
can also obtain further information on main-
tenance work, for example.
Special service requirements
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions
or increased loads, for example:
R
regular city driving with frequent intermedi-
ate stops
R
if the vehicle is primarily used to travel
short distances
R
for frequent operation in mountainous ter-
rain or on poor road surfaces
R
if the engine is often left idling for long peri-
ods
In these or similar operating conditions, have
the air filter, engine oil and oil filter, for exam-
ple, changed more frequently. The tyres must
be checked more frequently if the vehicle is
operated under increased loads. Further
information can be obtained at a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Mercedes-Benz Service24h" section
of the Service Booklet.
AdBlue ® service indicator
i For BlueTEC vehicles only.
To function properly, BlueTEC exhaust gas
aftertreatment must be operated with the
reducing agent AdBlue
® . AdBlue ® is topped
up as part of the service. Under normal oper-
ating conditions, a full tank of AdBlue
® should
last until the next service due date.
Depending on how and where the vehicle is
used, there may be an increase in the
AdBlue
® consumption, resulting in the next
service due date being brought forward.
Certain display messages show that
AdBlue
® must be topped up, e.g.:
Refill AdBlue at workshop See Own‐
er's Manual
Refill AdBlue at workshop No start
in .. km
A warning signal also sounds.
You can no longer start the engine when the
AdBlue
® supply has been used up
( Y page 277).
! Have the AdBlue ® tank topped up at a
qualified specialist workshop only. The
vehicle may otherwise be damaged or
soiled.
Before taking a trip with your vehicle outside
Europe, have the AdBlue
® supply checked at
a qualified specialist workshop. If necessary,
have AdBlue
® topped up. Before a longer stay
outside of Europe, consult a qualified special-
ist workshop.
Observe the notes on AdBlue
® ( Y page 409).
Further information about BlueTEC exhaust
gas aftertreatment and AdBlue
® can be
obtained at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
