Airbags
Never apply stickers or adhesive-
backed objects of any kind to the
airbag covers. Never attempt to reup-
holster the covers or modify them in any
way. If the airbags deploy in response
to an accident, if you note any signs of
system malfunction, or if you wish to
have any parts of the airbag passenger-
restraint system deactivated, always
contact your BMW center, to whom we
strongly urge you to entrust all testing,
repair and dismantling operations.
Never attempt to modify or tamper with
either the system's electrical wiring or
any of its individual components.
System components include the uphol-
stered surfaces on the steering wheel,
instrument panel, the trim panels on the
front and rear doors (with rear airbags)
and the roof braces as well as the sides
of the headliner above the doors.
Never attempt to remove or dismantle
the steering wheel.
To ensure compliance with official
safety regulations, always entrust
disposal of airbag generators to your
BMW center. Attempts to carry out
service procedures undertaken by
anyone other than specially-trained
professionals can result in system
failure or undesired airbag deployment,
both of which can lead to personal
injury. If the airbags deploy in response
to an accident, always remember to
avoid all contact with system compo-
nents, as they are hot and can cause
burns in the period immediately
following deployment.<
All vehicle occupants should
always sit upright and be properly
restrained (infants and small children in
appropriate child-restraint systems;
larger children and adults using the
safety belts). Never let an occupant's
head rest near or on a side airbag: the
inflating airbag could cause a serious or
fatal injury. Please note that the word
"Airbag" imprinted on the door trim
panel indicates the airbag's location.
Accident research shows that the
safest place for children in an automo-
bile is in the rear seat. However, a child
sitting in the rear seat and not properly
restrained may place his or her head on
or near the side airbag, if installed. For
example, a child Ð even though belted Ð
may fall asleep with his or her head
against the side airbag. It may be diffi-
cult for a driver to ensure that children
in the rear seat will remain properly
positioned at all times and do not place
their heads on or near the side airbag.
Therefore, we recommend that the
rear-seat side airbags, if provided, be
deactivated if you plan to transport chil-
dren in the rear seat.
The rear-seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW
center. Labels in the rear door opening
should indicate the status of your rear-
seat side airbags. If you are uncertain of
their status, or wish to have the airbags
activated or deactivated, please
contact your BMW center.<
Even when all these guidelines are
followed, there is still a small residual
risk of injuries to the face, hands and
arms occurring in isolated instances.
The ignition and inflation noise may
provoke a mild temporary hearing loss
in extremely sensitive individuals.
Airbag warning information is also
provided on the sun visors.

Indicator lamp
The indicator lamp indicates the
operational status of the airbag
system from ignition key posi-
tion 1.
System operational:
>The indicator lamp comes on briefly
then goes out.
System malfunction:
>The indicator lamp fails to come on
>The indicator lamp comes on briefly
before going out and then lighting up
again.
Please respond to any malfunctions in
the system by immediately having it
inspected at your BMW center; other-
wise the airbag could fail to respond to
an accident in which both the angle and
the severity of the impact would
normally trigger airbag deployment.

lock.
Individual electrical accessories are
ready for operation.Starting engine
Vehicles with manual transmis-
sion: depress the clutch when
starting the engine. A lockout prevents
the engine from starting with the clutch
engaged.<
Before starting>Engage the parking brake
>Be sure that the transmission is in
"Neutral" (or "Park" if the vehicle is
equipped with an automatic trans-
mission)
>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 engineStarting the engineDo not press the accelerator pedal
while starting the engine.
While it is important not to release
the key prematurely, you should
also avoid allowing the starter to
operate continuously for more than
20 seconds at a time. Release the igni-
tion key immediately as soon as the
engine starts.
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
release it immediately.
The starter continues to operate auto-
matically and will be deactivated as
soon as the engine starts.
The automatic starting mode will not
operate if the battery voltage is low.
The engine can be jump-started using
an external power source (refer to
page 162).<
Do not allow the engine to warm up
by leaving it running while the vehicle
remains stationary. Instead, begin to
drive immediately at a moderate engine
speed.
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 of roughly +5 7 (Ð15 6) or below
and at altitudes of over 3,300 ft
(1,000 m):
>Allow the starter to turn somewhat
longer (approximately 10 seconds)
during your initial starting attempt.
Engine idle speed is controlled by the
engine-management system. Higher
idle speeds at startup are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging,
always deactivate electrical devices
that are not in use. Switch the ignition
off when the vehicle is not being driven.Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to catalyst
damage.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in serious
personal injury and property damage.<

Vehicles with automatic transmission:
The vehicle must be stationary and the
selector lever in "Park" before you can
remove the ignition key.
The parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates on the rear wheels.To engageThe lever engages automatically and
the "PARK BRAKE" or "BRAKE" (in
Canada "P") indicator lamp comes on in
the instrument cluster in ignition key
position 2. Refer to pages 19 and 20.To releasePull up slightly on the lever, press the
button and lower the lever.390de714
If, in exceptional circumstances, it
should be necessary to engage
the parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling up the lever to apply
moderate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear.
The brake lamps do not come on when
the parking brake is applied.
Vehicles with manual transmission:
Always engage the parking brake
when parking on hills and inclined
surfaces, as first gear or reverse may
not provide adequate resistance to
rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<
You can help prevent corrosion and
avoid uneven braking response by
gently engaging the parking brake from
time to time when coasting to a stop at
traffic lights (ensure that you will not
pose a hazard to other road users).

engine from starting if the clutch is not
depressed.360de044
BMW 540iWhen shifting gears, always depress
the clutch pedal all the way to the end
of its travel, then move the shift lever
until it engages securely in the desired
gear.
You will also need to depress the clutch
when starting the engine, as an auto-
matic lockout prevents the starter from
operating when the clutch is engaged.
When shifting gears in the
5th/6th-gear plane, be sure to
press the shift lever to the right in order
to prevent inadvertent selection of a
gear in the 3rd/4th-gear plane.< 380de044
