134 Driving and operation
Controlling exhaust emission
Through design-related measures,
primarily in the fuel injection and ignition
systems (in combination with the catalytic
converter), the proportion of noxious
materials in the exhaust, such as carbon
monoxide (CO), hydrocarbons (CH) and
nitrogen oxides (NO ), is reduced to a
x
minimum.
Control indicator for exhaust emissions
Control indicator Z illuminates for a few
seconds when the ignition is switched on.
If it illuminates when the engine is running,
there is a fault in the emission control
system or with the diesel particle filter 3.
The permitted emission values may be
exceeded. Consult a workshop.
Flashing with the engine running indicates
a fault that may damage the catalytic
converter. The vehicle's electronic system
will switch to an emergency running
program so you may continue to drive
without causing damage, by slowing down
until the flashing stops and the control
indicator is steadily lit. Consult a workshop
immediately.
Control indicator for engine electronics
Control indicator 3 illuminates for a few
seconds when the ignition is switched on.
If it illuminates when the engine is running,
there is a fault in the engine electronics.
The electronics switch to the emergency
running program, fuel consumption may
increase and the driveability of the vehicle
may be affected.
In some cases, the fault can be eliminated
by switching the engine off and back on
again. If the control indicator illuminates
again when the engine is running, have the
cause of the fault eliminated by a
workshop.
