Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
GWARNING
If you are driving and reach through the steer- ing wheel to operate the adjustment knob,
you could lose control of the vehicle. There is
a risk of an accident and injury.
Only operate the adjustment knobs when thevehicle is stationary. Do not reach through the
steering wheel when driving.
You must observe the legal requirements for the
country in which you are currently driving when
operating the on-board computer.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer display only shows mes-
sages and warnings from certain systems. You
should therefore make sure your vehicle is oper-
ating safely at all times. If the operating safety of
your vehicle is impaired, stop the vehicle as
soon as possible, paying attention to road and
traffic conditions. Then consult a qualified spe-
cialist workshop.
The accuracy of the speedometer and odometer
displays is legally prescribed. Determining the
speed is dependent on the wheel size or the
rolling circumference of the wheels. If you
change the wheel size on your vehicle, make
sure it is assigned to the correct wheel size cat-
egory (
Ypage 277). If you change wheel size
category without recoding the control unit, the
speedometer indication will be inaccurate. Driv-
ing safety and driving systems may be impaired
or detect a malfunction and shut down.

found under "Instrument cluster":
