General information
Service notifications can be displayed on the
control display.
Vehicle features and options
This chapter describes model-specific equip-
ment, systems, and functions that are currently
available, or may become available in the fu-
ture, even if they are not present in the vehicle.
Additional information:
Service notifications, refer to page 149.
Additional information:
Service data in the vehicle key
Vehicle equipment, refer to page 8.
Information on the service notifications is con-
tinuously stored in the vehicle key. An author-
ized service center can read this data out and
suggest a maintenance scope for the vehicle.
Maintenance system
Therefore, hand the service advisor the vehicle
key with which the vehicle was driven most
recently.
Principle
The maintenance system provides service no-
tifications and thereby provides support in
maintaining road safety and the operational
reliability of the vehicle.
Stationary periods
Stationary periods during which the vehicle
battery was disconnected are taken into ac-
count.
General information
In some cases, scopes and intervals of the
maintenance system may vary according to
the country version. Replacement work, spare
parts, fuels and lubricants, and wear materials
are calculated separately. Further information
is available from an authorized service center
or another qualified service center or repair
shop.
Have any time-dependent maintenance meas-
ures, e.g., replacing operating fluids, performed
by an authorized service center or another
qualified service center or repair shop.
Maintenance Booklet for US
Models
Please consult your Maintenance Booklet for
additional information on the performance of
service and maintenance work.
Condition Based Service
Principle
The manufacturer of the vehicle recommends
that maintenance and repair be performed by
an authorized service center or another quali-
fied service center or repair shop. Records of
regular maintenance and repair work should
be retained.
Condition Based Service determines the main-
tenance recommendation using sensors and
special algorithms that take into account the
operating conditions of the vehicle.
The system makes it possible to adapt the
maintenance measures to your user profile.

Safety information
Exhaust emissions
NOTICE
▷
The warning light illuminates:
The socket for Onboard Diagnosis is an in-
tricate component intended to be used in
conjunction with specialized equipment to
check the vehicle’s primary emissions sys-
tem. Improper use of the socket for Onboard
Diagnosis, or contact with the socket for On-
board Diagnosis for other than its intended
purpose, can cause vehicle malfunctions and
creates risks of personal and property dam-
age. As such, it is strongly recommended that
access to the diagnostic socket be limited to
an authorized service center or another quali-
fied service center or repair shop, or other
persons who have specialized training and
equipment and who are able to use the diag-
nostic socket correctly.
The exhaust gas quality is declining,
e.g., because the fuel filler cap is
fitted incorrectly. Have the vehicle
checked as soon as possible.
▷
The warning light flashes under certain cir-
cumstances:
This indicates that there is excessive misfir-
ing in the engine.
Reduce the vehicle speed and have the ve-
hicle checked immediately; otherwise, se-
rious engine misfiring within a brief pe-
riod can seriously damage emission control
components, in particular the catalytic con-
verter.
Have the vehicle checked by an authorized
service center or another qualified service cen-
ter or repair shop.
Taking the vehicle out of
service
When the vehicle is shut down for longer
than three months, special measures must
be taken. For more information, contact an
authorized service center or another qualified
service center or repair shop.
