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.
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.

WARNING
•If you do not pay attention to the warning lights coming on and
the corresponding descriptions and warning notes, this may result
in severe body injuries or major vehicle damage.
•The engine compartment of your car is a hazardous area. There
is a risk of injuries, scalding, accid ents and fire when working in the
engine compartment, e.g. inspecting and replenishing oil and other
fluids. It is also essential to observe all warnings ⇒page 219.
Note
•Arrangement of the indicator lights depends on the model and model
version. The symbols shown in the following functional description are to
be found as indicator lights in the instrument cluster.
•Operational faults are shown in the display of the instrument cluster as
red symbols (priority 1 - danger) or yellow symbols (priority 2 - warning).
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.

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. 211 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 the filter is full, the engine control
unit gives the injection system a command for an additional injection of
fuel with additive into the cylinders so that an automatic cleaning of the
filter is carried out during suitable operating conditions. The additive is
located in a special reservoir under the spare wheel. A higher temperature
in the entire diesel particle filter is achieved as a result of this and thus self-
ignition and following combustion of soot particles occurs. The regenera-

tion procedure lasts about 2 to 3 minutes and is performed without driver
interference.
If the engine control unit detects that the operating conditions for a regen-
eration (combustion of deposited soot particles) of the diesel particle fiter
are not optimal, e.g. slow city driving, a warning light in the instrument
cluster is illuminated
. In order to clean the diesel particle filter, the
vehicle should be driven at an even speed of at least 60 km/h for approx.
5 - 10 minutes. The diesel particle filter is most effectively cleaned if the
vehicle is driven in the 4th or 5th gear within the range of 2 000 to 3 000
rpm.
If these conditions are not met, the warning light
does not go out and
after 10 minutes the warning light begins to flash. ENGINE
WORKSHOP! is shown in the information display*. Afterwards the engine
control unit shifts the engine into the emergency mode, which only has a
reduced power output. After switching the ignition off and on again the
warning light
comes on.
Have the vehicle inspected without delay by your specialist garage.
WARNING
•Please pay attention to the traffic regulations and speed limits.
•The diesel particle filter achieves very high temperatures.
Therefore do not park at points where the hot filter comes into
direct contact with dry grass or other combustible materials - risk
of fire!
•Use neither protective paint for chassis nor anti-corrosion
agent, in order to treat the exhaust system, the heat shields or the
diesel particle filter. The high temperatures can cause the coating
to ignite!
Note
•The servicing of the diesel particle filter and the replenishing of the
additive are performed by a specialist garage in the framework of the
regular inspection, see Service shedule.
•It is prohibited to use biofuel (RME) and diesel fuel mixture for diesel
vehicles which are fitted with diesel particle filter.
Glow plug system (diesel engine)
The indicator light lights up for a cold engine when switching on the
ignition (pre-heat position) 2 ⇒ page 121. 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 programme which enables you to drive to the nearest
specialist garage by adopting a gentle style of driving.
