Emission control
Certain systems of the engine serve to keep
the toxic components of the exhaust gases
within permissible limits required by law.
These systems will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the
engine should, therefore, be carried out only
by qualified Mercedes-Benz Center
authorized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service
procedures must be carried out regularly
according to Mercedes-Benz servicing
requirements. For details refer to the
Maintenance Booklet. G
Warning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times. Maintenance
Notes
The Maintenance System in your vehicle
tracks the distance driven and the time
elapsed since the last maintenance service.
It calculates other maintenance service work
required, and calls for the next maintenance
service accordingly.
We strongly recommend that you have your
vehicle serviced at an authorized Mercedes-
Benz Center. Have it serviced in accordance
with the Maintenance Booklet at the times called for by the maintenance service
indicator.
i
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in
vehicle damage not covered by the
Mercedes-Benz Limited Warranty. Maintenance service indicator
message
Information on maintenance work and
maintenance intervals are specified in the
Maintenance Booklet. Contact an authorized
Mercedes-Benz Center, or visit
www.mbusa.com (USA only) for additional
information.
The maintenance service indicator message
will notify you when the next maintenance
service is required.
Starting approximately 1 month before the
next maintenance service is required, one of
the following messages will appear in the
multifunction display. The messages will
appear while you are driving or when you
switch on the ignition (example service A):
Service A Due In XXXX Miles (Km)
Service A Due In XX Days
Service A Due In X Day

Safety notes
A battery should always be sufficiently
charged in order to achieve its rated service
life. Refer to Maintenance Booklet for battery
maintenance intervals.
If you use your vehicle mostly for short-
distance trips, you will need to have the
battery charge checked more frequently.
When replacing a battery, always use a
battery approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, contact an
authorized Mercedes-Benz Center about
steps you need to observe. G
