MAINTENANCE AND SERVICE
||
IMPORTANT
If the following instruction is not observed
then the Start/stop function may temporar-
ily cease to work after the connection of an
external battery or battery charger:
The negative battery terminal on the
•
car's starter battery must never be
used for connecting an external starter
battery or battery charger – only the
car's negative charging point may be
used as the grounding point.

NOTE
If the starter battery has been discharged
so much that the car has no normal electri-
cal functions and the engine is then jump-
started with an external battery or a battery
charger, the Start/stop function may con-
tinue 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 bat-
tery 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 func-
tion is temporarily deactivated until the
battery has been recharged by the car. In
an outside temperature 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 temperature, the charging
time may increase to 3–4 hours. The rec-
ommendation is to charge the battery
using an external battery charger.
