Average fuel consumption
The average fuel consumption since the memory was last erased is
shown in the display in litres/100 km ⇒page 18. This information can help
you to adapt your style of driving to the fuel consumption you wish to
achieve.
If you wish to determine the average fuel consumption over a certain
period of time you must first erase the memory at the start of the new
measurement using the button ⇒page 19, fig. 6 . A zero appears in

Turn signal system
Either the left or right indicator light flashes depending on the posi-
tion of the turn signal lever.
The indicator light flashes at twice its normal rate if a turn signal light fails.
This does not apply when towing a trailer.
Switching off the hazard warning light system is switched on will cause all
of the turn signal lights as well as both indicator lights to flash.
Further information about the turn signal system ⇒page 59.
Main beam
The indicator light comes on when the main beam is selected or also
when the headlight flasher is operated.
Further information about the main beam ⇒page 59.
Low beam
The indicator light comes on when low beam is selected ⇒page 55.
Rear fog light
The warning light comes on when the rear fog lights are operating
⇒ page 57.
Alternator
The warning light comes on after the ignition has been switched on. It
should go out after the engine has started.
If the warning light does not go out after the engine has started, or comes
on when driving, drive to the nearest specialist garage. The vehicle battery
will be discharged in this case so switch off all non-essential electrical
components.
The following text will be displayed in the information display*:
ALTERNATOR WORKSHOP! (ALTERNATOR WORKSHOP!)
Caution
If the warning light comes on when driving and in addition the warning
light (cooling system fault) also comes on in display, you must then
stop the car immediately and switch the engine off - risk of engine
damage!
Fog lights*
The warning light comes on when the fog lights are operating
⇒ page 57.
Cornering lights*
If the warning light flashes for 1 minute while driving or after switching
on the ignition and a warning signal sounds, a fault is confirmed.

Turn signal system for vehicles towing a trailer*
The indicator light on vehicles towing a trailer flashes together with the
respective indicator light for the turn signal system.
The indicator light
does not flash if a turn signal light on the trailer or
on the vehicle is not operating.
Coolant temperature/coolant level
The warning light comes on for a few seconds 1) when the ignition is
switched on.
The coolant temperature is too high or the coolant level too low if the
warning light
does not go out after the engine is started or flashes while
driving.
3 peeps sound as an additional warning signal.
In this case stop and switch the engine off and check the coolant level;
top up the coolant as necessary ⇒page 217, “Replenishing the coolant”.
Do not continue your journey if for some reason it is not possible under
the conditions prevailing to top up with coolant. Keep the engine switched off
and obtain professional assistance from a specialist garage,
otherwise it could lead to severe engine damage.
If the coolant is within the specified range, the increased temperature may
be caused by an operating problem at the coolant fan. Check the fuse for
the coolant fan, replace it if necessary ⇒page 253, “Fuse assignment at
battery”.
Do not continue driving if the warning light does not go off although the
fluid is at the correct level and also the fuse of the fan is in proper order.
Contact a specialist garage to obtain assistance.
Please also refer to the additional instructions ⇒page 215, “Cooling
system”.
The following text will be displayed in the information display*:
STOP CHECK COOLANT OWNER'S MANUAL!
WARNING
•If you must stop for technical reasons, then park the vehicle at
a safe distance from the traffic and switch off the engine and switch
on the hazard warning light system ⇒page 59, “Switch for hazard
warning lights ”.
•Pay attention to the following instructions ⇒page 210,
“Working in the engine compartment” before checking the coolant
fluid level and opening the bonnet.
•Take care when opening the coolant expansion bottle. If the
engine is hot, the cooling system is pressurized - risk of scalding.
It is best to allow the engine to cool down before removing the cap.
•Do not touch the coolant fan! The coolant fan may switch on
automatically even if the ignition is off.
1)The warning light on vehicles fitted with information display does not come on
after switching the ignition on, but only if the coolant temperature is to\
o high or the
coolant level is too low.

WARNING
•If you must stop for technical reasons, then park the vehicle at
a safe distance from the traffic and switch off the engine and switch
on the hazard warning light system ⇒page 59.
•The red oil pressure light is not an oil level indicator! One
should therefore check the oil level at regular intervals, preferably
after every refueling stop.
•Pay attention to the following instructions ⇒page 210,
“Working in the engine compartmen t” before checking the coolant
fluid level and opening the bonnet.
Thickness of the brake pads*
If the warning light comes on, contact a specialist garage immediately
and have the brake pads on all of the wheels inspected.
A peep sounds as an additional warning signal.
The following text will be displayed in the information display*: CHECK BRAKE PAD
Open door*
The warning light comes on if one or several doors, the bonnet or tail-
gate is opened.
The warning light comes on even when the ignition is switched off. The
warning light goes out 5 minutes after switching off the ignition if one or
several doors, the bonnet or tailgate is opened. The warning light goes out
after closing the doors.

Selector lever lock* (automatic gearbox)
If the warning light lights up, operate the brake pedal. This is neces-
sary, in order to be able to move the selector lever out of the position P or
N .
Electronic stability programme (ESP)*
The warning light comes on for a few seconds when the ignition is
switched on.
Components of the ESP system also include the Traction Control System
(TCS), Electronic Differential Lock (EDL), and the Antilock Brake System
ABS (ABS).
The warning light comes on when driving when a control cycle is acti-
vated.
The warning light will come on and remains on if the ESP is switched off
or if there is a fault in the system.
The fact that the ESP system operates together with the ABS means that
the ESP warning light will also come on if the ABS system is not operating
properly.
Further information on the ESP ⇒page 177, “Electronic stability
programme (ESP)*”.
Electronic Differential Lock (EDL)*
The EDL is a part of the ESP. A fault in the EDL is indicated by the ESP
warning light
in the instrument cluster. Have the vehicle inspected
immediately by your specialist garage. Further information on the EDL
⇒ page 179.
Antilock brake system (ABS)*
The warning light shows the functionality of the ABS.
The warning light comes on for a few seconds after the ignition has been
switched on or when starting the engine. The warning light goes out after
an automatic check sequence has been completed.
A fault in the ABS
The system is not functioning properly if the ABS warning light
does
not go out within a few seconds after switching on the ignition, does not
light up at all or lights up while driving. The vehicle will only be braked by
the normal brake system. Visit a specialist garage as quickly as possible
and adjust your style of driving in the meantime since you will not know
how great the damage is.
Three additional warning tones will sound if there is a major fault in the
ABS.
Further information about ABS ⇒page 181, “Antilock brake system
(ABS)*”.
A fault in the entire brake system
If the ABS warning light
comes on together with the brake system
warning light (handbrake must be released), there is a fault not only in
the ABS but also in another part of the brake system ⇒.
The following text will be displayed in the information display*: STOP BRAKE FAULT OWNER'S MANUAL!
WARNING
•If the brake system warning light comes on together with the
ABS warning light stop the vehicle immediately and check the
brake fluid level in the reservoir ⇒page 218, “Brake fluid”. If the
fluid level has dropped below the MIN marking, do not drive any
