AirbagsThe illustration depicts schematically
the primary directions of vehicle impact
which initiate an airbag deployment.
The airbags will not be triggered in
the event of a minor accident, a
vehicle roll-over, or collisions from the
rear.c390de142
Operational status
The indicator lamp displays 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.
A system malfunction could prevent the
system from responding to an impact
occurring within its normal response
range.
Have the system checked by your
BMW center immediately.
Sitting correctly with airbags
For your safety, comply with the
following instructions for the
airbags. If you do not, the airbags may
not be able to provide their maximum
protection. All passengers in the vehicle
should be aware of and comply with
this information:
Even though there is an airbag, wear a
safety belt every time you get in the
vehicle, because airbags enhance
safety by providing added protection.
Make sure you are seated comfortably
in your seat, in such a way that you al-
ways maintain control, and are not too
close to the steering wheel.
Always hold the steering wheel by the
rim to keep any chance of injury to
hands or arms to an absolute minimum,
should the airbag be deployed.
No one and nothing is to come between
the airbag and the seat occupant.
Do not use the cover panel above the
front passenger-side airbag as a
storage area.

64n
AirbagsDo not apply adhesive materials to the
cover panels of the airbags, cover them
or modify them in any other way.
Do not install a rear-facing child re-
straint system in the front passenger
seat of this car.
Children under 13 years of age and
children less than 5 ft (150 cm) tall
should ride only in the rear seat.
Infants or small children should never
be held on the lap of a passenger.
If your car is equipped with side airbags
in the rear passenger area, be sure that
child restraints are mounted correctly
and provided with the greatest-possible
distance between the airbags in the
side trim panels. Do not allow children
to lean out of the child's seat in the di-
rection of the side trim panels. If they
do so, serious injuries can occur if the
airbag is triggered.< At all times, occupants should sit
upright and be properly restrained
(infants and small children in appropri-
ate child restraint systems; larger chil-
dren and adults using the safety belts).
Never let an occupant's head rest near
or on a side airbag because the inflating
airbag could cause a serious or fatal in-
jury. Please note that the word "Airbag"
imprinted on the door trim panel indi-
cates 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 so equipped.
For example, a child – even though
belted – may fall asleep with his or her
head against the side airbag. It may be
difficult for a driver to ensure that chil-
dren in the rear seat will remain prop-
erly positioned at all times and not
place their heads on or near the side
airbag.
Therefore, we recommend that the rear
seat side airbags, if provided, be deac-
tivated if you plan to transport children
in the rear seat.
The rear seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW cen-
ter. Labels in the rear door opening
should indicate the status of your rear
seat side airbags. If your are uncertain
of their status, or wish to have the air-
bags 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 from airbag deployment
in isolated instances. The ignition and
inflation noise may provoke a mild tem-
porary hearing loss in extremely sensi-
tive individuals.
Airbag warning information is also
provided on the sun visors.
For additional information concerning
the airbag system, refer to pages 176
and 206.

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.<

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.

Parking brake Manual transmissionThe parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates against 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 22 and 23.To releasePull up slightly on the lever, press the
button and lower the lever.390de042
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 mod-
erate 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 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:

To avoid corrosion, apply the parking
brake lightly from time to time when
coasting to a standstill (at a traffic sig-
nal, for instance), provided that it is safe
to do so.
BMW 525i, BMW 530iEvery time you shift gears, always
depress the clutch pedal all the way
down, pushing the manual-shift gear
lever into the respective end position.
Depress the clutch even when starting
the engine, otherwise, a lock will pre-
vent the engine from being started.
The shift lever's neutral gate (dot in the
illustration) is located between 3rd and
4th gears.
When shifting from each gear into
"Neutral," the shift lever returns auto-
matically to this neutral position be-
cause of its spring loading.360de044

In addition, the wipe interval is varied
automatically depending on road
speed.
Rain sensor:
When the rain sensor is activated, the
windshield wiper is controlled automati-
cally, depending on the degree of wet-
ness of the windshield (in both snow
and rain). You do not have to be con-
cerned with switching the windshield
wiper on or off or adjusting the wipe in-
terval between intermittent and full
wipe. Instead, you can concentrate fully
on the traffic conditions. This is espe-
cially important under adverse weather
conditions.
The rain sensor is positioned on the
windshield, directly ahead of the inte-
rior rearview mirror.
To activate the rain sensor:
From ignition key position 1 and up,
move the lever to position 1. The wipers
travel once across the windshield,
regardless of the weather.
