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.
An acoustic warning sounds when you
fail to remove the ignition key after
opening the driver's door.
Vehicles with automatic transmission:
Do not move the selector lever from
position "P" until the engine is running
(ignition key position 2).
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).390de010

Starting the engineBefore starting>Engage the parking brake
>Be sure that the transmission selector
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 car unattended with the
engine running. An unattended vehicle
with a running engine represents a po-
tential safety hazard.<
Starting the engine>Start the engine. Do not press the
accelerator pedal.
BMW 528i, BMW 540i with man-
ual transmission:
Do not actuate the starter for too short
a time. Do not turn it for more than ap-
prox. 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 182).<
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 (Ð156)
and at elevations above 3,300 feet
(1,000 meters):
>It may be necessary to allow the
starter to remain engaged somewhat
longer than under normal operating
conditions (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 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 discharg-
ing, always deactivate electrical de-
vices which are not in use. Switch the
ignition off when the vehicle is not
being driven.

matically to this neutral position be-
cause of its spring loading.
When shifting gears in the 5th/
6th-gear plane, be sure to press
the gear lever to the right in order to
prevent inadvertent selection of a gear
in the 3rd/4th-gear plane.< 380de044
ReverseSelect "Reverse" only when the vehicle
is stationary. Press the shift lever to the
left to overcome the resistance.
As you do this, the backup lamps will
turn on automatically when the ignition
key is in position 2.
Do not hold the vehicle in place on
slopes by slipping or "riding" the
clutch. Use the parking brake instead.
A slipping clutch increases clutch
wear.<

Cruise controlTo deactivate the cruise controlWhen the system is activated, press
button 4. The indicator lamp stays on.
You can use the cruise control again as
desired.
In addition, the system is also automati-
cally deactivated in response to the fol-
lowing conditions:
>When you apply pressure to the
brake pedal
>When you apply pressure to the
clutch pedal, and when you move the
automatic transmission selector le-
ver from "Drive" to "Neutral"
>If you exceed or fall below the pro-
grammed speed for an extended pe-
riod (by depressing the accelerator,
for example).
To resume the stored settingPress button 3:
The vehicle accelerates to and main-
tains the last speed stored. When you
turn the ignition key to position 0, the
stored speed is deleted from the sys-
tem's memory and the system is deacti-
vated.To deactivate the systemWhen the cruise control has been can-
celed, press button 4 again. The indica-
tor lamp goes off and the memorized
speed is canceled.Do not use cruise control on twist-
ing roads, when high traffic den-
sity prevents driving at a constant
speed, when the road surface is slick
(snow, rain, ice), or when the road sur-
face is loose (rocks or gravel, sand).<

Disc brakesDriving notesWhen driving in wet conditions and in
heavy rain, it is a good idea to apply
light pressure to the brake pedal every
few miles (kilometers). Watch traffic
conditions to ensure that this maneuver
does not endanger other road users.
The heat which is generated by the
brake applications helps to dry the
brake pads and rotors.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique de-
scribed below (refer to page 131).
Extended or steep mountain descents
do not necessarily have to lead to re-
duced braking efficiency. Shift down to
a gear in which only minimal periodic
brake applications are required or move
the selector lever to the appropriate
lower range with automatic transmis-
sion.
You can increase the engine's braking
effect by selecting progressively lower
gears, downshifting as far as 1st gear,
or the 1st or 2nd shift position, on steep
descents.Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining low to moderate pressure over
an extended period of time, you should
decelerate by applying more substantial
pressure to the brake pedal (watch for
following traffic!), then releasing the
pedal, then repeating the application.
This staggered braking technique al-
lows the brakes to cool in the intervals
between active braking phases, pre-
venting overheating and ensuring that
full braking capacity remains available
at all times.
Do not coast with the clutch de-
pressed or with the transmission
or selector lever in neutral. Do not coast
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed or the transmission
is in neutral, and there is no power-as-
sist for braking or steering when the
engine is not running.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Dynamic Brake Control (DBC)
*
If you apply the brakes rapidly, this sys-
tem automatically produces the maxi-
mum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops."
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
In the event of a malfunction, the yellow
warning lamp comes on. Conventional
braking efficiency is available without
limitations.
Have the system checked and repaired
at your BMW center as soon as possi-
ble.
For "Information for your safety"
covering the ABS system, refer to
page 128. This information also gener-
ally applies for DBC.<

Winter operationRubber seals and components In order to prevent the weather-strip-
ping from freezing, apply BMW rubber
treatment or silicone spray to the seals
on the doors, hood and luggage com-
partment lid/tailgate.
A full range of car-care products is
available from your BMW center.< Snow chainsBMW snow chains
* can be mounted on
both summer and winter tires. Mount
them in pairs on the rear wheels only
and comply with the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
For maximum traction, we recommend
that you manually deactivate the
ASC+T/DSC
* when driving with snow
chains mounted. Refer to page 91.
Starting offWe recommend that you use the man-
ual control switch to deactivate ASC+T/
DSC
* when starting off in deep snow or
when rocking the car to free it (refer to
page 91).
Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. Adapt
your speed and driving style when ap-
proaching grades or slopes. Maintain
an adequate distance between yourself
and the car ahead.BrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
The resulting increases in braking dis-
tance are considerable and should be
kept in mind at all times.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response. If the ABS does not respond in a critical
braking situation and the wheels lock:
Reduce the pressure on the brake
pedal until the wheels just start to roll
again while still maintaining enough
force to continue braking.
Following that, increase pedal pressure
again. Reduce the pressure as the
wheels lock, then reapply pressure.
Repeat this procedure. This type of
staggered braking will reduce the brak-
ing distance, and the vehicle still re-
mains responsive to steering.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.
Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, which could result in the loss of
vehicle control.<
Depress the clutch during hard
braking on road surfaces which
provide only poor or uneven traction.<

Skid controlRelease the accelerator pedal and
depress the clutch pedal. Countersteer
carefully and attempt to regain control
of the vehicle.ParkingEngage 1st or reverse gear. If your car
is equipped with an automatic transmis-
sion, place the selector lever in "Park."
On vehicles with manual transmission,
also apply the parking brake when
parking on inclined surfaces. In order to
prevent the parking brake linings from
locking due to frost or corrosion, dry
them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic is
not endangered.
The brake lamps do not come on
when the parking brake is
applied.<
If there is a change in steering behavior,
for instance greater steering effort or if
steering becomes lighter as speed
increases in vehicles equipped with
Servotronic
*:
Contact your BMW center immediately
for an inspection.
If the power steering fails,
increased effort will be required
to steer the vehicle.<
The warning lamp for the level
control system comes on, or the
message "LEVEL CONTROL
INACTIVE" appears in the Check Con-
trol: There is a malfunction in the level
control system.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
(left rear compared to right rear),
consult the nearest authorized BMW
center. Drive with appropriate caution
in the meantime. The vehicle has
reduced ground clearance or driving
comfort is noticeably reduced.
Even if the attitude of the vehicle is
normal, you should consult the nearest
authorized BMW center if the warning
lamp indicates a system fault.
