the standard and optional equipment of
your COMAND Online system, as available

WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for
the country in which you are currently driving when operating COMAND Online.
COMAND Online calculates the route to the
destination without taking account of the fol- lowing, for example:
R traffic lights
R stop and give way signs
R parking or stopping restrictions
R road narrowing
R other road and traffic rules and regulations
COMAND Online may give incorrect driving
recommendations if the data on the digital
map does not correspond to the actual con-
ditions. For example, a route may have been diverted or the direction of a one-way street
may have changed.
For this reason, you must always observe
road and traffic rules and regulations during
your journey. Road and traffic rules and reg-
ulations always have priority over the sys-
tem's driving recommendations.
Bear in mind that, at a speed of only 50 km/ h,
your vehicle covers a distance of nearly 14 m
per second. Declarations of conformity

vant provisions of Directive 1999/5/EC. You

General notes Operational readiness of the navigation
system
In vehicles for certain countries, the naviga-
tion system is not operational immediately
after delivery. The digital map is not pre-
installed.
If this is the case, the following message
appears in the display after you switch to nav-
igation mode:
Please insert the map DVD to acti‐ Please insert the map DVD to acti‐
vate navigation vate navigation.
X To install the digital map: (Ypage 382).
The navigation system must determine the
position of the vehicle before first use or
whenever operational status is restored.
Therefore, you may have to drive for a while
before precise route guidance is possible.
GPS reception
Correct functioning of the navigation system
depends, amongst other things, on GPS
reception. In certain situations, GPS recep-
tion may be impaired, there may be interfer-
ence or there may be no reception at all, e.g.
in tunnels or multi-storey car parks.
i The functionality of a roof aerial (tele-
phone, GPS) may be impaired if roof carri-
ers are used.
Entry restriction
On vehicles for certain countries, there is a
restriction on entering data.
The restriction is active above a vehicle speed of approximately 5 km/h. The restriction is Navigation

Radio Data System (RDS) General notes
The Radio Data System (RDS) provides inaud-
ible additional information in the FM wave-
band. The system consists of a listening
receiver and a monitoring receiver.
The monitoring receiver permanently scans
the FM waveband and collects certain data
from all receivable stations. This includes, for
instance, reception quality and RDS data
such as programme names and alternative
frequencies. COMAND Online stores the data and constantly updates the memory. The
audio receiver is therefore able to switch
automatically to an alternative frequency with
a better signal.
i RDS only functions for stations which
transmit RDS data.
Switching RDS on/off
You can use the Frequency fix (radio mode) or Station fix (DAB mode) functions to prevent
COMAND Online from switching between the
alternative frequencies of a station. This is
useful, for example, when the same content is broadcast with a time delay, or when there is
interference on one of the frequencies.
