Introduction
i This function

is currently not available for
Canada.
For the reception of weather forecasts via
satellite radio, you will need a SIRIUS XM
Satellite Weather subscription.
When the Call SIRIUS to activate
system at 888-539-7474 message with the
SIRIUS device identification number appears,
you will first have to obtain access to the
weather service. A description of the procedure can be found in the "Registering
satellite radio" section
(Y

page 416).
COMAND can receive weather forecasts via
satellite radio for the entire USA (including
Alaska and Hawaii). The received weather
data can be displayed as an information chart
(daily forecast, five-day forecast, detailed
information) or on the weather map.
The weather data received from a weather
station is stored in COMAND for one hour. It
can therefore be displayed again immediately
after restarting the engine (for example after
refueling).
The weather map can display the following
weather data with symbols:
R rain radar
R storm characteristics
R areas of high-pressure/low-pressure,
weather fronts
R course of tropical cyclones (hurricanes,
typhoons)
R wind direction and speeds
i The rain radar cannot be displayed for
Alaska, Hawaii and Puerto Rico.
i Hurricane: term used to describe the
tropical cyclones that primarily develop in
the Atlantic, North Pacific and South Pacific
oceans. The wind speeds are above
74 mph (118 km/h). Five categories are
used to classify the strength of a hurricane.
Typhoon: term used to describe a tropical
cyclone that develops in the northwestern
Pacific. The wind speeds are in the category
of a hurricane. SIRIUS Weather
