The following readouts of the selected memory will be set to zero by
button :
•average fuel consumption,
•distance driven,
•average speed,
•driving time.
You can only operate the multi-functional indicator when the ignition is
switched on. After the ignition is switched on, the function displayed is the
one which you last selected before switching off the ignition.
The outside temperature indicator will appear with a snowflake symbol
and a warning signal sounds* when the outside temperature lies between
+5°C and -5°C. The symbol warns the driver of the possible danger of ice
on the road. After the rocker switch is pressed, the function displays
the one which you last selected before switching off the ignition.
The outside temperature
The outside temperature appears in the display when the ignition is
switched on.
The correct outside temperature will be indicated with a delay of 5
minutes. If the vehicle is stationary (or driven at a very low speed) the
temperature indicated may be slightly higher than the actual outside
temperature because of heat radiated by the engine.
The outside temperature indicator will appear with a snowflake symbol
(warning signal for ice on the road) and a warning signal sounds* when
the outside temperature lies between +5°C and -5°C.
WARNING
Do not only rely upon the information given on the outside temper-
ature display that there is no ice on the road. Please note that black
ice may also be present on the road surface even at temperatures
around +5°C - warning, drive with care!
Note
The outside temperature is not indicating when showing navigation data
(guidance to the destination). It must be called up over the menu (valid for
vehicles which have a navigation and information display).
Range
The estimated range in kilometres is shown on the display. It indicates the
distance you can still drive with your vehicle based on the present level of
fuel in the tank for the same style of driving. The readout is shown in steps
of 5 km.
The fuel consumption for the last 50 km is taken as a basis for calculating
the range. If you drive in a more economical manner from this moment on,
the range will be increased accordingly.
You first drive 50 km if the readout is reset (after disconnecting the battery)
before a new readout for the range is displayed.
Fuel - present consumption
The current fuel consumption level is shown in the display in litres/100 km.
This information can help you to adapt your style of driving to the fuel
consumption you wish to achieve.

The warning light comes on when the rear fog lights are operating
⇒ page 58.
EPC fault light (petrol engine)
The (Electronic Power Control) warning light comes on for a few
seconds when the ignition is switched on.
There is a system fault in the engine control system if the warning light
does not go out or comes on or flashes while driving. The engine manage-
ment system selects an emergency programme which enables you to
drive to the nearest specialist garage by adopting a gentle style of driving.
The following text will be displayed in the information display*:
ENGINE WORKSHOP! (ENGINE FAULT - WORKSHOP!)
Diesel particle filter (diesel engine)
In the diesel particle filter the resulting soot particles are
collected and burnt during the combustion of diesel fuel.
Code 7GG on the vehicle data sticker ⇒fig. 17 indicates that
your vehicle is equipped with a diesel particle filter. The vehicle
data sticker ⇒ page 269, fig. 207 is located on the floor of the
luggage compartment and is also stated in the Service schedule.
The soot particles, which result from the combustion of diesel fuel, are
collected in the diesel particle filter . If soot particles have gathered in the
filter, the engine control unit gives the injection system a command for an
additional injection of fuel with additive into the cylinders. The additive is
located in a special reservoir in the fuel tank. A higher temperature in the
entire diesel particle filter is achieved as a result of this and thus self-igni-
tion and following combustion of soot particles occurs. The regeneration
procedure lasts about 2 to 3 minutes and is performed without driver inter-
ference.

If the engine control unit detects that the operating conditions for the
regeneration are not optimal (e.g. slow city driving), an indicator light in
the instrument cluster is illuminated. The soot particles must be burned in
the filter. The combustion is performed when you are driving at least 60
km/h for 5 to 10 minutes. The warning light goes out.
If the warning light remains on despite this measure, the following text
appears in the display of the instrument cluster*: ENGINE WORKSHOP!
(ENGINE FAULT WORKSHOP!) . In this case contact a specialist garage
to obtain assistance.
WARNING
•Please pay attention to the traffic regulations and speed limits.
•It is prohibited to use biofuel and diesel fuel mixture (RME) for
diesel vehicles which are fitted with diesel particle filter.
Note
The servicing of the diesel particle filter and the replenishing of the addi-
tive are performed by a specialist garage in the framework of the regular
inspection, see Service shedule.
Glow plug system (diesel engine)
The indicator light lights up for a cold engine when switching on the
ignition (pre-heat position) 2 ⇒ page 122. Start the engine just as soon as
the indicator light goes out.
The glow plug indicator light will come on for about 1 second if the engine
is at a normal operating temperature or if the outside temperature is
above +5°C. This means that you can start the engine right away.There is a fault in the glow plug system if the indicator light
does not
come on at all or lights up continuously. Contact a specialist garage as
soon as possible to obtain assistance.
There is a system fault in the engine control system if the warning light
has started to flash while driving. The engine management system selects
an emergency program which enables you to drive to the nearest
specialist garage by adopting a gentle style of driving.
The following text will be displayed in the information display*:
ENGINE WORKSHOP! (ENGINE FAULT - WORKSHOP!)
Coolant temperature, Coolant quantity
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.
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.
1)The warning light on vehicles fitted with information display comes on after
switching the ignition on
