Technical data sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.
Anti-lock brake system (ABS)
The warning lamp monitors the ABS and the electronic
differential lock (EDL).The warning lamp
lights up for a few seconds when the ignition
is switched on and while the engine is being started. The lamp goes
out again once the system has run through an automatic test
sequence.
There is a fault in the ABS if:
•
the warning lamp
does not light up when the ignition is
switched on,
•
the warning lamp does not go out again after a few seconds,
•
the warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the
ABS control function is out of action). Please take the vehicle to a
qualified workshop as soon as possible. For further information on
the ABS ⇒page 132.
If a fault occurs in the ABS, the ESP warning lamp will also light up.
Fault in the main brake system
If the ABS warning lamp
lights up together with the brake
warning lamp
⇒page 35, this indicates a fault in the ABS func-
tion, and possibly a malfunction in the main brake system as well
⇒.
If there is a malfunction in the brake system the symbol
will light
up in the instrument cluster. Please refer to ⇒page 18.Fault on the electronic differential lock (EDL)
The EDL works in conjunction with the ABS. If a malfunction should
occur in the EDL, this is indicated by the ABS warning lamp
.
Please take the vehicle to a qualified workshop as soon as possible.
For further information on the EDL ⇒page 132.
WARNING
•
If the brake warning lamp
lights up together with the ABS
warning lamp
, the brake fluid level in the reservoir is too low
and this may cause an accident. Stop the vehicle and do not drive
on. You should obtain professional assistance.
•
If the brake fluid level is OK, the fault in the brake system may
have been caused by a failure of the ABS control function. As a
result the rear wheels can lock relatively easily when braking. This
could cause the tail of the vehicle to skid sideways. Drive carefully
to the nearest qualified workshop and have the fault rectified.

vated via the button and the rocker switch on the wind-
screen wiper lever ⇒fig. 12.The main menu lists the different display types (for technical
reasons, illustrations in this manual are in German language):

The time (in minutes, seconds and tenths of a second) is shown in
the instrument cluster display. The hour automatically appears in
the display if the session lasts for over an hour. The maximum time
which can be recorded in a single measurement is 99 hours,
59 minutes, 59 seconds and 9/10 of a second. If this time is
exceeded, the lap timer will automatically stop recording and switch
to the pause mode ⇒page 29.
WARNING
Please direct your full attention to the road at all times! As the
driver, you have full responsibility for the safety of the vehicle and
other road users. For this reason, you should only use the func-
tions in a manner that allows you to maintain control of the
vehicle in all situations - accident risk!
Note
The on-board computer can be used in the normal way while the
stopwatch of the lap timer is running.

The speed warning function can help you keep below a
pre-set maximum speed.
The speed warning function will warn you if the vehicle exceeds the
pre-set maximum speed. 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. 28.
The speed warning function has two different warning levels*,
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.
The speed limit warning symbol
for speed warning 1 ⇒fig. 28
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 32.
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 you need to keep below a particular
speed 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 stored value again.
