MAINTENANCE AND SERVICE
||
NOTE
If the starter battery has been discharged so
much that the car has no normal electrical
functions and the engine is then jump-started
with an external battery or a battery charger,
the Start/stop function may continue to be
activated. If the Start/stop function then auto-
stops the engine shortly afterwards, there is a
great risk that engine auto-start will fail due
to insufficient battery capacity, because the
battery has not had the time to recharge.
If the car has been jump-started, or if there is
insufficient time to charge the battery with a
battery charger, the Start/stop function is
temporarily deactivated until the battery has
been recharged by the car. In an outside tem-
perature of approx. +15 °C (approx. 60 °F),
the battery needs to be charged for at least
1 hour by the car. In a lower outside tempera-
ture, the charging time may increase to
3–4 hours. The recommendation is to charge
the battery using an external battery charger.
