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 after, there is a
great risk that engine auto-start will fail due
to insufficient battery capacity, because the
battery has not had the opportunity to
recharge.
If the car has been jump-started, or if there is
insufficient time to charge the battery with a
battery charger, the recommendation is to
temporarily deactivate the Start/Stop function
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 recommenda-
tion is to charge the battery using an external
battery charger.
