Technical Data
The warning lamp should light up for a few seconds when the ignition is
switched on. It should go out once the engine is started.
If the battery is disconnected, the indicator remains lit, even with the engine
running. The warning light only goes off after a distance of approx. 50 m.
There is a fault in the electromechanical steering system if the lamp does not
go out or lights up whilst the vehicle is in motion. The indicator may appear
in two different colours to indicate faults. If it lights yellow, this indicates a
minor fault. If it lights red, seek workshop assistance immediately, if no
assistance is available stop driving. Stop the vehicle and seek technical
assistance. The power steering does not work if the battery is flat or if the
engine is off (for example, for towing). You should take into account that you
will need considerably more power than normal to steer the vehicle if the
steering assistance is reduced or has failed completely.
For those vehicles fitted with ESP* the function “Recommended steering
manoeuvre” is included. See
⇒page 183.
Emission control system*

This warning lamp monitors the exhaust system.
Warning lamp
 flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest qualified workshop to have the
engine checked.
The dash panel displays the following message
17): EXHAUST GAS SEE
WORKSHOP . Warning lamp
 is lit:
If a fault has developed during driving which has reduced the quality of the
exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to
the nearest qualified workshop to have the engine checked.

Electronic stabilisation programme (ESP)*

This warning lamp monitors the electronic stabilisation
programme.
This programme includes the ABS, EDL and TCS. This also includes the brake
assist system (BAS), automatic cleaning of the brake discs and the trailer
stability programme (TSP).
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 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 func-
tional.
If the ESP button is activated, the TCS function deactivates and the warning
lamp flashes.
