Trailer turn signals
The indicator lamp flashes when the turn signals are
operated while towing a caravan or trailer.
The indicator lamp flashes when the turn signals are operated,
provided a caravan or trailer is correctly attached and connected to
the vehicle.
The indicator lamp will not flash if one of the turn signals on the
trailer fails.
Seat belt warning lamp
The warning lamp acts as a reminder to fasten the seat
belts.
After switching on the ignition, the warning lamp will remain lit
until the driver and front passenger (if applicable) have fastened
their seat belts. When the vehicle has gathered speed you will also
hear a warning chime.
For further information on the seat belts ⇒ page 160.
Emission control system
If the warning lamp lights up continuously you should take your
vehicle to a qualified workshop as soon as possible in order to have
the fault rectified.
If the warning lamp flashes drive on at reduced speed and seek
professional help in order to avoid damage to the catalytic
converter.
For further information on the catalytic converter ⇒ page 195.

Applies to vehicles: with cruise control system
Cruise control
The indicator lamp in the instrument cluster lights up when the
cruise control system is operating.
Anti-lock brake system (ABS)
The warning lamp monitors the ABS and the electronic
differential lock (EDL).
The warning lamp lights up for a few seconds when the ignition
is switched on and while the engine is being started. The lamp goes
out again once 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,
• the warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the
ABS control function is out of action). Please take the vehicle to a
qualified workshop as soon as possible. For further information on
the ABS ⇒ page 187.
If a fault occurs in the ABS, the ESP warning lamp will also light up.
