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.

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:
Place the selector lever in "Park."<
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

If the indicator lamp comes on
or if the message "TRANS.
FAILSAFE PROG" appears in
the Check Control
*, there is a malfunc-
tion in the transmission system.
Bring the vehicle to a stop, select the
"Park" position, apply the parking brake
and shut the engine off (ignition key po-
sition 0). Restart the engine after a few
seconds. If the indicator lamp goes out
again after a few seconds, the normal
transmission functions have been re-
stored. You may continue to drive as
usual.
If the indicator lamp does not go out,
you can place the selector lever in all
positions. However, the vehicle will now
only drive forward with limited gear
selection.
Under these circumstances, avoid ex-
treme engine loads and consult the
nearest BMW center.
Do not work in the engine com-
partment when a drive gear (for-
ward or reverse) is engaged. If you do
this, the vehicle could move.<

Upshifts or downshifts will be carried
out by the ATC only at appropriate
engine speeds and road speeds. For
instance, if engine speed is too high, a
downshift will not be executed. The
gear selected will appear briefly in the
instrument cluster followed by the
current gear.
If you are driving in the manual
mode and wish to accelerate
rapidly from low road speeds (when
passing, for instance), you must shift
down manually or with the "Kickdown"
function.<
You can only change from "M/S" to
selector lever positions "P," "R," and
"N" via the "D" position.
In the following situations, the Step-
tronic "thinks" for you in the manual
mode:
>In order to prevent engine over-
speeding, the transmission shifts
automatically to the next higher gear.

You can set the wipe interval to four
stages with rotary dial 7.
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.

or the intensive cleaning 6.
To modify the sensitivity of the rain
sensor:
Turn rotary dial 7.
To deactivate the rain sensor:
Move lever to position 0.
Turn the rain sensor off in auto-
matic car washes. Failure to do so
could result in damage caused by un-
desired wiper activation.< 2 Normal wiper speedThe wipers automatically revert to inter-
mittent operation when the vehicle is
stationary (not on vehicles with rain
sensor
*).
3 Fast wiper speedThe wipers automatically revert to nor-
mal speed when the vehicle is station-
ary (not on vehicles with rain sensor
*).
5 Cleaning windshieldThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
If you only pull the lever briefly, the sys-
tem sprays washer fluid onto the wind-
shield without activating the wipers.6 Intensive cleaning
*
As in setting 5. In addition, an intensive-
action washer fluid is first sprayed on
the windshield.
For changing the wiper blades, refer to
page 182.
Cleaning headlamps
*
If they are on, the headlamps will also
be cleaned every fifth time you activate
cleaning windshield (5) or intensive
cleaning (6).
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, otherwise vi-
sion could be obscured. For this rea-
son, use an antifreeze agent. Refer to
page 164.
Do not use the washers when the reser-
voir is empty, since this could cause
damage to the washer pump. Windshield washer jetsThe windshield washer jets are warmed
automatically when the ignition key is in
position 2.
