Controlling exha ust em ission
Through d esign-related mea sures,
primarily in the fuel injec tion and ig nition
systems (in combination with the catalytic
converter), the p roportion of noxious
materials in the exhaust, such as carbon
monoxide (CO), hydrocarbons (CH) and
nitrog en oxides (N O
x
), is reduced to a
minimum.
Control indica tor for exhaust emissions
Control indica tor Z illuminates for a few
second s w hen the ignition is switched on.
If it i lluminates when the engine is running,
there is a fa ult in the em ission control
system or with the d iesel pa rticle filter 3 .
The permitted emission values may b e
exc eeded. Consult a workshop.
Flashing with the engine running indicates
a fault that may damage the catalytic
conv erter. The vehicle’s electronic system
will switch to an emergency running
prog ra mme so you may continue to drive
without causing dama ge, by slowing d ow n
until the fla shing stop s and the control
indica tor is steadily lit. Consult a workshop
immed iately.
