Auto-check systemIntroductionThe auto-check system checks important components and vehicle systems.
These background checks are run consta ntly, as long as the ignition is
switched on.
A message is displayed in the instrument panel if a fault should occur or if any
maintenance or repairs are urgently required. This is accompanied by an
audible warning signal. Depending on the pr iority of the fault, a red or yellow
warning symbol lights up in the display.
The red symbols indicate a danger, whereas the yellow ones represent a
warning . Additional messages to assist the driver may be shown with the red
or yellow symbols.

The red symbols are used to indicate a Priority 1 fault (serious malfunction).
A red symbol is accompanied by
three warning chimes. The symbols will keep
flashing until the faults are corrected. If several Priority 1 faults are detected
at the same time, the symbols are displayed one after the other for about 2
seconds.
Fault in the brake system
A fault in the brake system should be rectified as soon as
possible.If the symbol
flashes in the display, there is a fault in the brake
system. One of the following messages will appear in the display
together with the symbol:
Stop vehicle, check brake fluid and hydraulic fluid levels
Warning! Fault in brake system (ABS) Please visit garage
– Stop the vehicle.
–Check the brake fluid level ⇒ page 222.
If the ABS fails, the ABS warning lamp
will light up together with the brake
system fault symbol
⇒ .
WARNING
•
Before opening the bonnet and checking the brake fluid level, observe
the warning information in ⇒page 213, “Work in the engine compart-
ment”.
•
If the brake fluid level in the reservoir is too low, this could result in an
accident. Do not drive on. Obtain technical assistance.
•
If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that the control fun ction of the ABS is out of action. As
a result, the rear wheels can lock relatively easily when braking. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent danger of skidding. Drive carefully to the
nearest specialist garage and have the fault rectified.
Fault in the cooling system
Faults in the cooling system must be rectified immediately.If the
symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
–Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒page 218.
– Add more coolant if necessary ⇒page 218.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the over heating may be caused by a malfunction
of the radiator fan.
WARNING (continued)

78If the alternator warning lamp lights up as well ⇒page 69, it is possible that
the drive belt has broken.
Caution
Do not drive on if the symbol
has come on to indicate a fault in the cooling
system, otherwise there is a risk of engine damage.
Engine oil pressure too low
If the engine oil pressure is too low the fault must be rectified
immediately.If the
symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
–Stop the vehicle.
– Switch the engine off.
– Check the engine oil level ⇒page 215.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒page 216.
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 regularl y, 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 chime. 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.
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 208.
Diesel particulate filter obstructed
If the symbol
lights up, you may be able to contribute towards automatic
filter cleaning by driving in the right manner. You should drive at a speed of
at least 60 km/h for about 15 minutes in 4th or 5th gear, at an engine speed
of around 2000 rpm. The increase in temperature will burn off any soot in the
filter. When cleaning is successful, the symbol switches off.
If the light on symbol
does not go off, take the vehicle to a specialist
garage to repair the fault.
For further information on the diesel particulate filter, see ⇒page 183.
WARNING
It is essential that you adjust your sp eed to suit the weather, road, terrain
and traffic conditions. The recommended driving speed must never lead to
the driver disregarding the traffic regulations.Light sensor/ rain sensor faulty
Automatic headlights / automatic wipers faulty
If the symbol appears, this means that the light sensor / rain sensor is not
working. For safety reasons, the dipp ed beam headlights will then be
switched on permanently when the light switch is set to the AUTO position.
However, you can still switch the lights on and off in the normal way with the

Bulb 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 sec onds). 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 249.
•
A “blown” fuse ⇒page 247, “Changing fuses”.
•
Faulty electrical wiring.
Have the components replaced or the wiring repaired as necessary by a
specialist garage.
WARNING
•
Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
•
The high voltage element of gas discharge lamps* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
Speed warning
Introduction
The speed warning function can help prevent you exceeding
a particular pre-set maximum speed.The speed warning function will warn the driver if a pre-set maximum speed
is exceeded. The system gives an audible warning signal if the set speed is
exceeded by about 10 km/h. A warning symbol will also appear in the display
⇒ fig. 55 .
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.

82The speed limit warning symbol
for speed warning 1 ⇒page 81, fig. 55
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 82.
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 th e road speed has dropped below the
set value again.
Setting speed limit warning 2 ⇒page 83.
Note
Please bear in mind that, even with the speed warning function, it is still
important to keep a eye on the car' s speed with the speedometer and to
observe the legal speed limits.
Setting speed limit warning 1
Use the CHECK button to set speed limit warning 1.Setting the speed limit
– Drive at the desired maximum speed.
– Press the CHECK button and hold it down until the symbol ⇒page 81, fig. 55 appears.
Clearing the speed limit
– Drive the vehicle at a minimum of 5 km/h.
– Press the CHECK button for at least two seconds.The speed warning symbol
lights up briefly in th e display when the button
is released to confirm that the selected speed has been stored. The speed
limit that has been selected remains stored until another speed is selected
