0 Steering lock engagedThis is the only position in which the
ignition key can be inserted and
removed.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
you hear the lock engage.
Once the ignition has been switched off
(ignition key in position 0 or pulled out),
the radio functions are still available for
approx. 20 minutes. Turn the radio back
on to use it.
Vehicles with automatic transmis-
sion:
Do not move the selector lever from
position "P" until the engine is running
(ignition key position 2).390de010
Your vehicle is equipped with an inter-
lock. Therefore, the ignition key cannot
be turned to position 0 and removed
until the selector lever is in position "P"
(Interlock).< 1 Steering lock disengagedYou will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.2 Ignition onAll electrical equipment and accesso-
ries are available for use.3 Starting the engineBefore starting
>Engage the parking brake.
>Put the manual-shift gear lever in idle
or in P for an automatic transmission.
>Step on the clutch pedal.
Do not allow the engine to run in
enclosed spaces. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Never leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<

Starting the engine Switching off the engineStarting the engine>Start the engine. Do not press the
accelerator pedal.
Do not actuate the starter for too
short a time. Do not turn it for
more than approx. 20 seconds. Release
the ignition key immediately as soon as
the engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle re-
mains stationary. Instead, begin driving
immediately at a moderate engine
speed.
BMW 540i with automatic transmission:
Your BMW is equipped with the conve-
nience starting feature. Simply turn the
key to position 3 (starter) and then re-
lease it immediately.
The starter continues to operate auto-
matically.
The automatic starting mode will not
operate if the battery voltage is low.
Should this condition arise, it remains
possible to jump-start the engine (refer
to page 200).<
Should the engine fail to start on the
first attempt (if it is very hot or cold, for
instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures, from approx. +57 (–156)
and at elevations above 3,300 ft
(1,000 meters):
>Be sure to let the starter remain
engaged somewhat longer the first
time (approx. 10 seconds).
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical de-
vices which are not in use. Switch the
ignition off when the vehicle is not
being driven.Turn the ignition key to position 1 or 0.
Never remove the ignition key
while the vehicle is rolling. The
steering locks, making it impossible to
steer the vehicle.
Always remove the ignition key and en-
gage the steering lock before leaving
the vehicle.
Vehicles with manual transmission:
Always engage the parking brake
when parking on slopes and inclined
surfaces, since not even placing the
lever in 1st gear or reverse may not
provide adequate resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<
Vehicles with automatic transmission
*:
The vehicle must be stationary and the
selector lever in "Park" before you can
remove the ignition key.
