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 three
seconds.
USING START-STOP
WARNINGS
The engine may restart
automatically if required by the
system. See Principle of Operation
(page 138).
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 the
engine is warm and the outside temperature
is between 0°C (32°F) and 30°C (86°F).
Note: If you stall the engine, and then
depress the clutch pedal within a couple of
seconds, the system will automatically
restart the engine.
Note: The Start-stop indicator will
illuminate green when the engine shuts
down. See Warning Lamps and Indicators
(page 80).
Note: The Start-stop indicator will flash
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: The system is on by default. To
switch the system off, press the switch in
the instrument panel. The system will only
be de-activated for the current ignition
cycle. To turn it on, press the switch again.
For item location. See At a Glance (page
11).
