Modifying the engine output

Increased power could:
change emission levels
R
cause malfunctions
R
lead to consequential damage
R
The operating safety of the engine cannot be
guaranteed in all situations.
Any tampering with the engine management
system in order to increase the engine power
output will lead to a loss of warranty entitle-
ments.

Safety/emergency running program

The engine is equipped with an electronic
engine management system that monitors the
engine and the exhaust gas aftertreatment unit
and has a self-diagnostic system.
If the electronic control system detects a mal-
function, one of the following measures is auto-
matically implemented after an appraisal of the
malfunction:
faults during operation are indicated by the
R
corresponding warning lamp (
in conjunction with the electronic engine
R
management system, fault codes with addi-
tional information can be shown on a display.
the system switches to a suitable backup
R
function for the continued, albeit restricted,
operation of the engine. This includes torque
and engine speed limitation, for example, as
well as road speed limitation or constant
emergency running speed.

Correct use

The engine system may only be installed as con-
tractually specified.
The manufacturer of the end product is respon-
sible for the correct installation of the engine
and the exhaust gas aftertreatment system in
the overall system.
The engine and the exhaust gas aftertreatment
system may not be modified. In the event of
modification, Mercedes-Benz does not accept
responsibility for any damage arising as a result.
Correct use of the engine system also requires
adherence to the instructions in these Operat-
ing Instructions. This also requires compliance
with the maintenance intervals and the profes-
sional execution of maintenance work. Please
observe the Workshop Information System
