system.
Starting
f

f
Do not press the accelerator pedal. The engine
control unit will provide the correct starting
mixture.

approx. 10 seconds. If necessary, repeat the
starting procedure after a pause of approx.
10 seconds. Turn the ignition key back to
position 3 first.
The first operation of the starter is ended automat-
ically when the engine starts.

operations will not be ended automatically.
f Do not warm up the engine when stationary.
Drive off immediately. Avoid high revolutions
and full throttle until the engine has reached
operating temperature.
If battery output is insufficient, jump leads can be
used to start the engine. Vehicles with manual
transmission can also be tow-started.
f Please observe the chapter “JUMP LEAD
STARTING” on page 218.
f To ensure a good charge condition for the
battery and thus its ability to start the engine,
all electrical accessories which are not
required should be switched off when the
ignition is switched on and when engine revolu-
tions are low (in traffic jams, in cities or in
queues).
