Seat, mirror and steering wheel memory Seat heating
*
Your BMW center can adjust your
vehicle's systems in such a
manner that your personalized settings
are automatically called up for the seat,
mirror and steering wheel positions
when you unlock the vehicle with your
personal remote control key.<
Before using the key memory fea-
ture to unlock the vehicle always
ensure that no objects are stored in the
footwell behind the driver's seat. If you
fail to do so, persons or objects could
be injured or damaged if the seat
should move backward.<
Passenger-side exterior mirror tilt
function(automatic curb monitor)
1 Move the mirror selector switch
(arrow) to the "driver's mirror" posi-
tion
2 When the gearshift lever or the
selector lever is placed in "Reverse,"
the passenger-side mirror tilts down-
ward to help the driver monitor the
area directly adjacent to the vehicle
during parking (curbs, etc.).
You can deactivate this automatic fea-
ture by setting the mirror selector
switch to the "passenger-side" posi-
tion.390de720
The seat cushion and backrest can be
heated with the ignition key in
position 2.
You can select from different heating
modes by repeatedly pressing the
button.
You can also switch the higher heating
modes off directly:
Press the button and hold it slightly
longer.390us729

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 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 dis-
posal of airbag generators to your BMW
center. Attempts to carry out service
procedures undertaken by anyone
other than specially-trained profes-
sionals 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 acci-
dent, always remember to avoid all
contact with system components, as
they are hot and can cause burns in the
period immediately following deploy-
ment.<
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 con-
tact your BMW center.<
Even when all these guidelines are fol-
lowed, 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 pro-
vided on the sun visors.

AirbagsThis is the right way for a child to sit in a
child restraint when rear side airbags
(arrow) are provided.380de637

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 nor-
mally trigger airbag deployment.

Vehicles with automatic transmis-
sion:
Do not move the selector lever from the
"Park" position until the engine is run-
ning (ignition key in position 2).
To turn the key back to position 0 (for
instance, prior to removal), start by
moving the selector lever to position P
(Interlock).<
Steering unlocked You 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.
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 gearshift lever is in
"Neutral" or the selector lever in
"Park" if the vehicle is equipped with
an automatic transmission
>Depress 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 164).<
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 (approx. 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 damage of the
catalytic converter.<
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 per-
sonal injury and property damage.<
