the instrument panel:
Rev counter
You should select a lower gear if the engine speed drops below 1500 rpm.
The start of the red zone on the dial indicates the maximum engine speed
which may be used when the engine is warm and after it has been run in
properly. Before reaching this zone, a higher gear must be selected or your
foot must be removed from the accelerator.
CAUTION
To prevent possible engine malfunctions, the rev counter needle should not
reach the red zone. The start of the red zone on the dial is different for some
engine versions.
For the sake of the environment
Changing up into higher gears sooner following the recommended gear in-
dications ⇒ Fig. 50 will help you to reduce fuel consumption, emissions and
also engine noise. Digital clock and date

Speedometer with odometer
The speedometer indicates the speed of the vehicle and the
distance travelled.
Fig. 42 Detailed view of
the instrument panel:
Odometer
The distance is normally stated in kilometres (km). On some models, how-
ever, the odometer will show “miles”.
Lower odometer
The lower odometer records the vehicle's total mileage.
Upper odometer (trip recorder)
The upper odometer shows the distance that has been travelled since the
trip recorder was last reset. It is used to measure short trips. The last digit of
the trip recorder indicates distances of 100 metres or tenths of a mile. The
upper odometer can be reset to zero by pressing the reset button ⇒ Fig. 42.
Fault display
If there is a fault in the instrument panel, the letters DEF will appear perma-
nently in the trip recorder display. Please have the fault repaired as soon as
possible. Electronic immobiliser
The vehicle key data is consulted when the ignition is switched on.
If an uncoded key is used, the message
SAFE will appear in the trip recorder
display. The vehicle can no longer be started if that happens. 
Fuel reserve
The display only works when the ignition is switched on.
When the needle reaches the reserve zone, the symbol  lights up in the
instrument panel display ⇒ page 83. At this point there are still about 8 to
10 litres of fuel left in the tank. This is your reminder to fill up soon.
You can consult the tank capacity of your vehicle in the ⇒ page 312, Di-
mensions and capacities section.
CAUTION
Never run the tank completely dry. If there is an irregular fuel supply, misfir-
ing can occur. This means that fuel could reach the exhaust system without
burning. This may lead to the catalytic converter reheating and being dam-
aged. 

Note
When the display shows route guidance instructions from the navigation
system, the outside temperature appears in the second line of the radio dis-
play. 
Gear display*
This display helps to save fuel.
Fig. 50 Gear display
Use the gear display to save fuel. The indication ⇒ Fig. 50 on the instrument
panel display recommends that you select the gear indicated by the arrow.
It may also skip a gear, and recommend changing up from 4th gear to 6th
gear, for example.
Note
● The display may not recommend any gear-change while you are acceler-
ating.
● The gear change indication should not be taken into account the accel-
eration is required (for example when overtaking).
● If desired, you can have the gear-change display deactivated by a Tech-
nical Service. 
Distance to empty
The distance to empty display can help you to plan your trip.
The estimated distance to empty is displayed in km. It shows how far the
vehicle can be driven with the amount of fuel left in the tank, assuming the
same style of driving. The distance to empty is displayed in increments of
10 km.
The distance to empty is calculated on the basis of the fuel consumption
over the last 30 kilometres. The distance to empty will increase if you drive
in a more economical manner. 

Engine oil level correct
If the  symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on! Do not continue to run the engine, even
at idle speed .
Note
The oil pressure warning lamp  is not an indicator for the oil level. The oil
level should therefore be checked regularly, preferably every time you fill
the tank. 

Yellow symbols are used to indicate a Priority 2 fault (warning).
Yellow symbols are accompanied by one warning buzzer. The function indi-
cated should be checked as soon as possible. If several Priority 2 faults are
detected at the same time, the symbols are displayed one after the other for
about 2 seconds at a time. 
Brake light failure 
This warning light will appear on the upper part of the display if any of the
brake lights has failed. A text message in the central part of the display indi-
cates which brake light has failed (left or right). 
Fuel level low 
When this symbol  comes on for the first time, there are about 8 to 10 li-
tres of fuel left in the tank. You should fill up as soon as possible
⇒  page 230. 
Engine speed governing 
Max. engine speed XXXX rpm
There is a fault in the engine management. In addition, the warning lamp 
on the instrument panel will light up. The engine speed will be governed to
the speed displayed in the driver information system. Please ensure that
the engine speed does not exceed the speed shown (for example, when
changing down a gear).
Take the vehicle to a specialised workshop immediately to have the fault re-
paired. Checking the engine oil level

If the  symbol lights up, please check the engine oil level as soon as pos-
sible ⇒ page 237. Top up the oil at the next opportunity ⇒ page 238.
Engine oil sensor defective* 
If the  symbol lights up, take the vehicle to a specialised workshop and
have the oil level sensor checked. Until then it is advisable to check the oil
level every time you fill up with fuel ⇒ page 237. 
Diesel particulate filter obstructed 
If the symbol  lights up, you can contribute towards automatic filter
cleaning by driving in the right manner. To do this, drive about 15 minutes
in 4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h,
with the engine running at approximately 2000 rpm. The increase in temper-
ature will burn off any soot in the filter. When cleaning is successful, the
symbol switches off.
If the symbol  does not turn off, or the three lamps turn on (particulate
filter , emission control system fault  and heaters ), take the vehicle
to a specialised workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒ page 203.
WARNING
It is essential that you adjust your speed to suit the weather, road, ter-
rain and traffic conditions. The recommended driving speed must never
lead to the driver disregarding the traffic regulations.

Onboard computer
Introduction
The onboard computer provides you with useful information
during a journey, including average and current fuel con-
sumption, average speed, distance to empty, driving time
and distance covered.
Fig. 59 Onboard com-
puter: memory 1
Press RESET button B

⇒  Fig. 60 to switch back and forward between on-
board computer functions 1 and 2.
The numbers in the display ⇒ Fig. 59 indicate which of the two memories is
currently in use. A 1 means that the display is showing the information in
the single journey memory (onboard computer 1). A 2 means that the dis-
play is showing the information in the total journey memory (onboard com-
puter 2). Single-journey memory (onboard computer 1)
The single-journey memory processes the information on a journey from the
time the ignition is switched on until it is switched off. If the journey is re-
sumed within two hours after the ignition is switched off, the new figures
are automatically included in the calculation. If the journey is interrupted for
more than two hours the stored information is automatically erased when
you resume your journey.
Total-journey memory (onboard computer 2)
Unlike the single-journey memory, the total-journey memory is not erased
automatically. Hence, you can determine the period for which you wish the
onboard computer to supply figures.
Distance to empty
The estimated distance to empty is displayed in km. The distance to empty
is displayed in increments of 10 km.
Average fuel consumption
This mode shows the average fuel consumption since the memory was last
cancelled in litres/100 km.
Instantaneous fuel consumption
The display shows the instantaneous fuel consumption in litres/100 km.
When the vehicle is stationary, the computer will display the last value in
the memory.
Average speed
This mode shows the average speed driven since the memory was last can-
celled (in km/h).
Driving time
This display shows the period of time which has elapsed since the memory
was last cancelled. The longest possible period it can cover is 999 hours
and 59 minutes.

Cockpit
Driving time warning
After 2 hours of continuous driving, the display automatically switches over
to the driving time display of 2:00. At the same time the driving time display
starts flashing. This is to remind the driver to take a break.
The driving time warning can be switched off by briefly pressing the func-
tion selector switch or the Reset
button ⇒ Fig. 60.
If you continue driving or take a break for less than 10 minutes, the driving
time warning will switch on once again when the total driving time is 4:00
hours, 6:00 hours, etc. However, if you take a break for more than 10 mi-
nutes, the driving time warning clock will be erased.
Distance covered
This display shows the distance you have covered since the memory was
last cancelled. The longest possible distance which can be recorded is
9999.9 km.
Note
● The displays for fuel consumption (average and instantaneous), dis-
tance to empty and speed are shown in metric units.
● The information in the memory is lost if the battery is disconnected. Operation
The onboard computer is controlled by means of two
switches on the windscreen wiper lever.
