Information abou
tService Resetting the ASSYST PLUS service inter-
val display
!
If the ASSYST PLUS service interval dis-
play has been inadvertently reset, this set-
ting can be corrected at a qualified special-
ist workshop.
Have service work carried out as described
in the Service Booklet. This may otherwise
lead to increased wear and damage to the
major assemblies or the vehicle.
Aq ualified specialist workshop, e.g. a
Mercedes-Ben zService 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
Arduous operating conditions or increased
loads on the vehicle will require some service
work to be performed more often than for a
vehicle in normal use. Such arduous condi-
tions include regular city driving with frequent
intermediate stops and use in mountainous
terrain or on poor road surfaces.
For example, if the vehicle is used under ardu-
ous operating conditions, have air filters,
engine oil and oil filters changed frequently
and chec kthe wheels often.F urther informa-
tion can be obtained at a qualified specialist
workshop, e.g. a Mercedes-Ben zService
Centre.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's curren ttelephone 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 nexts ervice 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.

arning tone also sounds.
You can no longer start the engine when the
AdBlue ®
supply has been used up
(Y page 281).
! 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 440).
