Note
After filling up, it can occur that during dy namic driving (e.g. numerous curves, braking,
driving downhill and climbing a steep hill) the fuel gauge indicates approx. a fraction
less. When stopping or during less dynamic driving, the correct fuel supply quantity is
indicated. This effect is not a fault.Counter for distance drivenThe distance which you have driven with yo ur vehicle is shown in kilometres (km). In
some countries the measuring unit “mile” is used.
Reset button
If you hold the reset button page 15, fig. 15 pressed for about 1 second, the trip
counter is set back to zero.
Trip counter for distance driven
The trip counter indicates the distance which you have driven since it was last reset -
in steps of 100 metres or 1/10 of a mile.
Counter for distance driven
The counter for distance driven indicates th e total distance in kilometers or miles
which the vehicle has been driven.
Fa u l t d i s p l a y
If there is a fault in the instru ment cluster, the constant text Error appears in the display.
Have the fault rectified as soon as possible by a specialist workshop.
WARNING
Never seek to adjust the trip counter for distance driven while driving for safety
reasons!
Note
If vehicles which are fitted with the inform ation display* the display of the second
speed is activated in mph or km/h, this driving speed is indicated instead of the
counter for the total distance driven.
Service Interval DisplayDepending on the equipment installed in the vehicle, the text can differ on the display.
Service Interval Display
Before the next service interval a key symbol
and the remaining kilometers are
indicated after switching on the ignition fig. 16 . At the same time, a display appears
regarding the remaining days until the next service interval.
The following will be displayed in the information display*:
Service in ... km or ... days
The kilometre indicator or the days indicator reduces in steps of 100 km. or days until

Technical Data
Multi-functional indicator (onboard computer)*IntroductionThe multi-functional indicator appears in the display fig. 18 or in the information
display page 22 depending on the equipm ent fitted to your vehicle.
The multi-functional indicator offers you a range of useful information.
On vehicles which are fitted out with information display*, it is possible to switch off
the display of some information.
Note
In certain national versions th e displays appear in the Imperial system of measures.
If the display of the second speed is ac tivated in mph, the current speed* is not
indicated in km/h on the display.
MemoryThe multi-functional indicator is equipped with two automatic memories. The
selected memory is displayed in the middle of the display field fig. 18 .
The data of the single-trip memory (memory 1) is shown if a 1 appears in the display.
A 2 shown in the display means that data relates to the total distance memory
(memory 2).
Switching over the memory with the help of the button page 20, fig. 19 on the
windscreen wiper lever or with the help of the button on the multifunction steering
wheel* page 20, fig. 19.
Single-trip memory (memory 1)
The single-trip memory collates the driving information from the moment the ignition
is switched on until it is switched off. New data will also flow into the calculation of the
current driving information if the trip is continued within 2 hours after switching off
the ignition. The memory will be is automatica lly erased, on the other hand, if the trip
is interrupted for more than 2 hours .
Total-trip memory (memory 2)
The total distance driven memory gathers data from any number of individual jour-
neys up to a total of 19 hours and 59 minutes driving or 1.999 kilometres driven and
on vehicles which are fitted with informatio n display* up to a total of 99 hours and 59
minutes driving or 9.999 kilometres driven. The memory is deleted when either of
these limits is reached and the calculation starts from anew.
The total-trip memory will not, contrary to the single-trip memory, be deleted after a
period of interruption of driving of 2 hours.

WARNING
Do not only rely upon the information given on the outside temperature 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 +4°C - warning, drive with
care!Driving timeThe driving time which has elapsed since the memory was last erased, appears in the
display. If you wish to measure the driving ti me as of a particular time, you must set the
memory to zero at this moment in time by pressing the button on the windshield
wiper lever page 20, fig. 19 or the handwheel on the multifunction steering
wheel* page 20, fig. 19 for longer than 1 second.
The maximum time indicated in both memories is 19 hours and 59 minutes and on
vehicles which are fitted with information display*, it is 99 hours and 59 minutes. The
indicator is set back to null if this period is exceeded.Current consumptionThe current fuel consumption level is shown in the display in litres/100 km. This infor-
mation can help you to adapt your style of driving to the fuel consumption you wish to
achieve.
The display appears in litres/hour if the vehicle is stationary or driving at a low speed.
The indicated value will be updated every 0.5 seconds while you are driving.Average fuel consumptionThe average fuel consumption since the memory was last erased is shown in the
display in litres/100 km page 19. This information can he lp 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 cert ain period of time
you must set the memory to zero at the start of the measurement using the button
on the windshield wiper lever page 20, fig. 19 or with the handwheel on the multifunction st
eering wheel* page 20, fig. 19 . A zero appears in the display for the
first 100 m you drive after erasing the memory.
The indicated value will be updated every 5 seconds while you are driving.
Note
The amount of fuel consumed will not be indicated.RangeThe estimated range in kilometres is shown on the display. It indicates the distance you
can still drive with your vehicle based on th e present level of fuel in the tank for the
same style of driving.
The readout is shown in steps of 10 km. Afte r lighting up of the indicator light for the
fuel reserve the display is shown in steps of 5 km.
The fuel consumption for the last 50 km is ta ken 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.
If the memory is set to zero (after discon necting the battery), the fuel consumption of
10 ltr./100 km is calculated for the range; afterwards the value is adapted accordingly
to the style of driving.Distance drivenThe distance driven since the memory was last erased appears in the display
page 19. If you wish to measure the distance driven of a particular time, you must
set the memory to zero at this moment in time by pressing the button on the wind-
shield wiper lever page 20, fig. 19 or the handwheel on the multifunction
steering wheel* page 20, fig. 19.
The maximum distance indicated in both memories is 1 999 km or on vehicles with
information display*, it is 9 999 km. The indicator is set back to null if this period is
exceeded.

Bulb failure
The warning light
comes on if a bulb is faulty:
up to 2 seconds after the ignition is switched on,
when switching on the defective light bulb.
The following text e.g will be displayed in the information display*: Check front right dipped beam!
The rear side lights and the licence plate li ghting require several light bulbs. The indi-
cator light
only lights up if all light bulbs of the licence plate lighting or the parking
light (in one rear light unit) are defective. Check regularly the function of the light
bulbs.
Diesel particle filter*
(diesel engine)
If the warning light
comes on, this means that soot has accumulated in the diesel
particle filter because of the frequent short distances.
In order to clean the diesel particle filter, the vehicle should be driven at an even speed
of at least 60 km/h at engine speeds of 1 800 - 2 500 rpm for at least 15 minutes or until
the warning light goes out with the 4th or 5th gear engaged (automatic gearbox: posi-
tion S) when the traffic situation permits it. This increases the exhaust temperature and
the soot deposited in the diesel particle filter is burnt.
Always pay attention to the valid speed limits .
The warning light
goes out after the successful cleaning of the diesel particle filter.
If the filter is not properly cleaned, the warning light
does not go out and the
warning light
begins to flash. In the information display* appears Diesel-particle:
Owner's manual . Afterwards the engine control unit shifts the engine into the emer-
gency 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
If you do not pay attention to the warning light coming on and the corre-
sponding descriptions and warning notes, this may result in injuries or major
vehicle damage.
Always adjust your speed to suit weather, road, region and traffic condi-
tions. The route indicated by the warnin g light must not tempt you to disregard
the national regulations for road traffic.Caution
As long as the warning light
li ghts up, one must take into account an incre as ed f uel
consumption and in certain circumstan ces a power reduction of the engine.
