Fault in the exhaust system*
Exhaust gas indicator
If the indicator flashes it signals possible damage to the catalytic
converter caused by defective combustion. Reduce speed immediately and
go to the nearest specialised workshop to check the engine. At the same
time, a text message or the necessary operations may appear on the instru-
ment panel.
If the indicator
lights up, a fault has developed during driving which has
affects the quality of the exhaust gas (e.g. lambda probe fault). Reduce speed
immediately and go to the nearest specialised workshop to check the engine.
At the same time, a text message or the necessary operations may appear on
the instrument panel.
Traction control system (TCS)*
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
The warning lamp lights up when the ignition is switched on and should turn
out after about 2 seconds.
When the TCS is operating while driving, the warning lamp flashes. If the
system is deactivated or if there is any fault in the same, the warning lamp will
remain lit.
It will also come on if a fault should occur in the ABS because the TCS oper-
ates in conjunction with the ABS. For further information see ⇒ page 183.
Electronic stabilisation programme (ESP)*
This warning lamp monitors the electronic stabilisation
programme.
This programme includes the ABS, EDL and TCS.
The warning lamp
has the following functions:
• It will light for about 2 seconds when the ignition is switched on while a
test of the function is carried out.
• It flashes when the ESP is activated when driving.
• It will light up continuously if there is a malfunction in the ESP.
• It will light up continuously if the ESP is switched off.
• It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp
lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESP.
In this case the ESP can be reactivated by switching the ignition off and then
on again. If the warning lamp goes out, this means the system is fully
functional.
Anti-lock brake system (ABS)
A warning lamp system monitors the ABS.
The warning lamp should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automatic
test sequence.
There is a fault in the ABS if:
• The warning lamp does not light up when the ignition is switched on.
• The warning lamp does not go out again after a few seconds.
