If the vehicle is not be used for a longer
period of time, do not disconnect the
consumer battery. Instead, maintain
the condition of the battery by using
the battery charger approved by
Mercedes-Benz for use on the SLR and
supplied with the car ( page 358).
This charger automatically controls the
charge rate, and can be left connected
to the car for long periods without damage
to the battery.
If the battery supplying the vehicle’s
electrical consumers is disconnected,
the days of disconnection will not be included
in the count shown by the service
indicator. To arrive at the true
service deadline, you will need to subtract
these days from the days shown
in the service indicator.
Do not confuse the maintenance
service indicator with the engine oil
level indicator :.
