Starting the engine
Cars with spark-ignition engine
Do not press the accelerator pedal
while starting the engine.
Allow the starter motor to run for a
reasonable time, but for no more
than about 20 seconds. As soon as the
engine fires, release the ignition key.
BMW 535iA, 540iA:
Your BMW is equipped with a conven-
ient-start system. It is sufficient to turn
the ignition key briefly to position 3 (to
operate the starter motor), then to
release it.
The starter then runs automatically for a
predetermined period, and cuts out as
soon as the engine has started.
If the battery voltage is low, automatic
starting cannot be activated, or the
function is interrupted. The engine can
be jump started (see page 173).
<
Do not warm up the engine with the car
at a standstill; it is preferable to set off
straight away, driving at moderate
engine speeds.
If the engine does not start at the first
attempt, for instance when it is
extremely hot or cold:
>
Depress the accelerator pedal
halfway while starting the engine.
Cold starts at very low ambient temper-
atures (below approx. 15

)athigh
altitude (more than 1,000 m (approx.
3,250 ft) above sea level):
>
On the first occasion, take longer
over the starting operation (approx.
10 seconds)
Excessively lengthy or frequent
operation of the starter motor at
short intervals can result in damage to
the catalytic converter.
<
Make sure that when driving the
car, standing with the engine
running or when parking, no easily
flammable material (hay, grass, leaves
etc.) comes into contact with the hot
exhaust system. It could ignite and
cause a fire, with the risk of severe
injuries or damage.

When the engine is cold:
>
Hold the ignition key in position 2

At extremely low temperatures, the
starter motor may have to be run for
up to 40 seconds.
When the engine is warm:
>
The preheat indicator light or display
does not come on. Start the engine
immediately.
Movement of the accelerator pedal has
no influence on the starting process.

standstill, but drive off as soon as
possible, using moderate engine
speeds.
Bleeding the fuel system: even if the
fuel tank has been run dry, the fuel
system does not normally need to be
bled.
If you nevertheless encounter difficul-
ties in starting the engine:
>
Run the starter motor for approx.
20 seconds.
