out when the engine has started running.
If the warning lamp  lights up while driving, the alternator is no longer
charging the battery. You should immediately drive to the nearest qualified
workshop.
You should avoid using electrical equipment that is not absolutely necessary
because this will drain the battery.
Tyre pressure

The tyre pressure control system controls the tyre speed and
the frequency spectrum of each tyre.The tyre monitor
13) compares wheel revolutions and with this information,
the diameter of each wheel using the ESP sensors. If the diameter of a wheel
changes, the tyre monitor indicator lights  . The wheel diameter changes
when:
•Tyre pressure is insufficient.•The tyre structure is damaged.•The vehicle is unbalanced because of a load.•The wheels of one axle are under more pressure (for example, driving with
a trailer or on extreme slopes).•The vehicle is fitted with snow chains.•The emergency wheel is fitted.

Tyre pressure adjustment
Following the modification to tyre pressure or after changing one or more
wheels, the button ⇒page 80, fig. 49 must be kept pressed while the igni-
tion is on until an acoustic signal is heard and the warning lamp goes out.
If the wheels are under excessive load (for example, driving with a trailer or
heavy load), the tire pressure must be increased to the recommended value
for a full load (see the sticker on the inside of the fuel flap). If the tyre monitor
system button is pressed down, the new tyre pressures are confirmed.
The tyre pressure monitor indicator
 lights up
If the tyre pressure of one or more wheels is much lower than the value set by
the driver, then the tyre control warning lamp lights up ⇒.
The tyre pressure monitor indicator  flashes
If the tyre pressure indicator flashes, this indicates a fault. Go to the nearest
specialist workshop.
WARNING
•When the tyre pressure indicator lights, reduce speed immediately and
avoid any sudden manoeuvre or braking. Stop when possible, and check
the tyre pressure and status.•The driver is responsible for correct tyre pressure. For this reason, tyre
pressure must be regularly checked.•Under certain circumstances (for example, in a sports situation, in
winter conditions or on a dirt track) the tyre monitor indicator may light or
function incorrectly.Note
If the battery is disconnected, the yellow indicator
 lights up after turning
the ignition on. This should turn off after a brief journey.

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.

EDL operates along with the ABS in vehicles equipped with an
Electronic Stabilisation Program (ESP)*A malfunction in the EDL is indicated by the ABS warning lamp
. Please
take the vehicle to a qualified workshop as soon as possible. For further infor-
mation on the EDL ⇒page 184, “Electronic differential lock (EDL)*”.
Traction control system (TCS)*
The traction control system prevents the driven wheels from
spinning when the vehicle is acceleratingThe 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 181,
