80Yellow 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 symbol s 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 litres
of fuel left in the tank. You should fill up as soon as possible ⇒page 220.
Engine speed governing
X
Max. engine speed XXXX rpm
There is a fault in the engine management. In addition, the warning lamp
% 0 #
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 qualified workshop immediately to have the fault
repaired.
Check engine oil level
If the
symbol lights up, please check the engine oil level as soon as
possible ⇒page 226. Top up the oil at the next opportunity ⇒page 227.
Engine oil sensor defective*
If the
symbol lights up, take the vehicle to a qualified 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 226.
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 temperature
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
D), take the vehicle
to a qualified workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒page 194.
WARNING
It is essential that you adjust your speed to suit the weather, road, terrain
and traffic conditions. The recommended driving speed must never lead to
the driver disregarding the traffic regulations.

82Bulb monitor
The bulb monitor checks whether the lights on the vehicle are
working.If a defective bulb is detected, or if one of the lights has failed for any reason,
the bulb monitor symbol
will appear in the display together with an addi-
tional message (which goes out after 5 seconds). For instance, if the rear left
turn signal is not working, the display in the instrument panel will show the
following message:
Left rear turn signal
The message disappears after 5 seconds. Press the CHECK button briefly if
you wish to call up the message again.
If the display indicates that one of the lights is not working, this can have a
number of causes:
•Bulb failure ⇒page 260.•A blown fuse ⇒page 258, “Changing fuses”.•Faulty electrical wiring.
It is not necessary to have lamps replaced in a specialised workshop,
however the use of Xenon lamps is recommended.
LED lamps
If any of the LED (Light Emitting Diode) functions fail, the complete lamp
should be replaced.
The failure of the lamp is only shown when the LED function goes out
completely. Sometimes, a LED will stop working, without displaying the
warning as the function continues to operate.
WARNING
•Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.•The high voltage element of gas discha rge bulbs* (xenon light) must be
handled correctly. Otherwise, there is a risk of death.

The speed warning function has two different warning speeds, which operate
independently and serve slightly different purposes:
Speed limit warning 1
With speed limit warning 1, the maximum speed can be changed while
driving. The speed limit that has been set remains stored until the ignition is
switched off, or until it is changed or cleared.
The warning symbol
for speed limit warning 1 ⇒page 82, fig. 56 will
appear in the display if you exceed the pre-set speed. It goes out again if the
speed is reduced below the set speed limit.
The symbol also goes out if the speed is increased to more than about
40 km/h above the set speed for at least 10 seconds. However, this does not
cancel the speed limit that was originally set.
Setting speed limit warning 1 ⇒page 83.
Speed limit warning 2
With speed limit warning 2, the speed limit can only be changed or cleared
when the ignition is switched off. You are recommended to store this speed
limit warning if you always wish to be reminded of a particular speed limit.
This could be when driving in countries with general speed limits, or if a
particular speed should not be exceeded when winter tyres are fitted etc.
The speed limit warning symbol
for speed warning 2 will appear in the
display if you exceed the pre-set speed. Unlike speed limit warning 1, the
warning symbol only goes out once the road speed has dropped below the
set value again.
Setting speed limit warning 2 ⇒page 84.
Note
Please bear in mind that, even with the speed warning function, it is still
important to keep a eye on the vehicle’s speed with the speedometer and to
observe the legal speed limits.Setting speed limit warning 1

Onboard computerIntroduction
The onboard computer provides you with useful information
during a journey, including average and current fuel
consumption, average speed, distance to empty, driving time
and distance covered.Press RESET button ⇒page 86, fig. 60 to switch back and forward
between onboard computer functions 1 and 2.
The numbers in the display ⇒ fig. 59 indicate which of the two memories is

single journey memory (onboard computer 1). A 2 means that the display is
showing the information in the total journey memory (onboard computer 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
resumed
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 t h e s t o r e d i n f o r m a t i o n i s a u t o m a t i ca l l y e r a s e d w h e n y o u

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
cancelled (in km/h).
