Important safety notes G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Introduction The digital maps generated by the map soft-
ware become outdated in the same way as
conventional road maps. Optimal route guid-
ance can only be provided by the navigation
system in conjunction with the most up-to-
date map software.
Information about new versions of the digital
map can be obtained from an authorized
Mercedes-Benz Center. You can have the dig-
ital map updated there with a DVD, or you can update it yourself.
Carrying out a manual update i
The update process can take a long time
(over an hour), depending on the size of the digital map. During this time, you will only
be able to switch on radio mode and to
accept incoming calls. The update will be
completed more quickly if the vehicle is
stationary.
If you start the update with the engine
switched off and the starter battery has
insufficient power, COMAND may automat-
ically switch off. This protects the battery. If 118
