Modifying the engine output
!
Increased power could:
R
change emission levels
R
cause malfunctions
R
lead to consequential damage
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 aftertreat-
ment unit and has a self-diagnostic system.
If the electronic control system detects a mal-
function, one of the following measures is
automatically implemented after an appraisal
of the malfunction:
R
faults during operation are indicated by the
corresponding warning lamp (
Y
page 39).
R
in conjunction with the electronic engine
management system, fault codes with addi-
tional information can be shown on a dis-
play.
R
the system switches to a suitable backup
function for the continued, albeit restric-
ted, 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
contractually specified.
The manufacturer of the end product is
responsible for the correct installation of the
engine and the exhaust gas aftertreatment
system in the overall system.
The engine and the exhaust gas aftertreat-
ment system may not be modified. If the
engine is modified, Mercedes-Benz and MTU
do not accept responsibility for any damage
arising as a result.
Correct use of the engine system also
requires adherence to the instructions in
these Operating Instructions. This also
requires compliance with the maintenance
intervals and the professional execution of
maintenance work. Please observe the Work-
shop Information System (WIS) (
Y
page 9).
