PRINCIPLE OF OPERATION
CAUTION
For vehicles with Start-stop the
battery requirement is different. It
must be replaced by one of exactly
the same specification as the original.
The system reduces fuel consumption
and CO2 emissions by shutting down the
engine when the vehicle is idling, for
example at traffic lights. The engine will
automatically restart when the driver
presses the clutch pedal or when required
by a vehicle system, for example to
recharge the battery.
To obtain maximum benefit from the
system, move the gear lever to the neutral
position and release the clutch pedal
during any stop of longer than 2 seconds.

The engine may restart
automatically if required by the
system. See Principle of
operation (page 134).
Switch the ignition off before
opening the bonnet or carrying out
any maintenance.
Always switch the ignition off before
leaving your vehicle, as the system
may have shut down the engine but
the ignition will still be live.
Note: The system only operates when

amber, requiring you to select neutral or
depress the clutch pedal. In conjunction
a message will be shown in the display.
Note: If the system detects a
malfunction, it is deactivated. Have the
system checked by a properly trained
technician.
Note: If you have switched the system
off, the switch will be illuminated.
Note: If you stall the engine, and then
depress the clutch pedal within a couple
of seconds, the system will automatically
restart the engine.
