ignition key in position

to allow the electronic system that
controls the motor-driven valves and the AC ECU to run a self-
acquisition process.
During this period, no devices must be activated.
The Motronic ECU self-acquisition cycle will only function correctly
when the intake air temperature is above 5 °C (41 °F).
After removing the battery from the vehicle or disconnecting it
from the electrical system using the battery master switch, it is
important to check that the external temperature is within the
indicated values when reconnecting before performing the self-
acquisition cycle.
Emergency starting
If the battery is flat, you can perform an emergency start by
connecting the special jump leads to the battery of another vehicle,
a portable jump starter or an external battery.
Important note
Emergency starting can only be performed with batteries with a
nominal voltage of 12V.
Important note
For emergency starting, only use leads that do not allow reverse
polarity, with sufficient cross-section and insulated clamps.
