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.<

Automatic transmission with Steptronic
*
ATC executes upshifts and downshifts
only when the new gear will provide a
suitable combination of vehicle and
engine speed, i.e., ATC will not execute
downshifts that would cause the engine
to overrev. 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.
Electronic transmission control
module
If the indicator lamp comes on
or the message "TRANS. FAIL-
SAFE PROG" appears in the
Check Control
*, there is a fault in the
transmission system.
Bring the vehicle to a stop. Move the
transmission selector lever to "P."
Engage the parking brake and turn the
engine off (ignition key to position 0).
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission
performance has been restored. 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.
If this happens, avoid extreme engine
loads and refer the problem to the
nearest BMW center.
Never perform work in the engine
compartment without first
ensuring that the transmission is in
"Park" or "Neutral" as the vehicle could
otherwise start to move off on its own.<
For jump-starting, towing and tow-
starting, refer to pages 164 and 165.

Washer/Wiper system
Turn the rain sensor off in auto-
matic car washes. Failure to do so
could result in damage caused by
undesired wiper activation.<
Normal wipeThe system automatically reverts to
operation in the intermittent mode
whenever the vehicle is stationary (not
on vehicles with rain sensor
*).
Fast wipeThe wipers revert to operation at
normal speed when the vehicle stops
(not on vehicles with rain sensor
*).
Clean the windshieldThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
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 152.Clean the headlamps
*
When the headlamps are on, they are
also cleaned automatically every fifth
time you activate the clean the wind-
shield (5) or intensive cleaning (6)
mode.
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, as your vision
could be obscured. Always use an anti-
freeze agent. Refer to page 141.
Do not use the washers when the reser-
voir is empty. 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.

Tachometer Energy control Fuel gaugeDo not operate the engine with the
needle in the red overspeed zone of the
gauge.
To protect the engine, the engine-man-
agement system interrupts the fuel
supply when you approach this sector.390us004
Indicates the current fuel consumption
in mpg (in liters/100 km on Canadian
vehicles). This allows you to see
whether your current driving style is
conducive to fuel economy with
minimum exhaust emissions.
When the vehicle is stationary, the dis-
play goes to "Maximum" (zero on Cana-
dian models).390us005
When you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
If the indicator lamp stays on, there are
approx.
>2.0 gal (8 liters) Ð
BMW 525i, BMW 530i
>2.5 gal (10 liters) Ð BMW 540i
of fuel still in the tank.
Tank capacity: refer to page 175
Certain operating conditions (such as
those encountered in mountainous
areas) may cause the needle to fluc-
tuate slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.< 390us006

OverviewControlsMaintenanceRepairsDataIndex
Air conditioningTemperature
The graduations on the dial
provide general reference
values for the interior temper-
ature. We recommend 70 7
(22 6) as a comfortable setting. When
you start the vehicle, this system
adjusts the air to the selected tempera-
ture as quickly as possible, and then
maintains that temperature constantly.
Air distribution
You can direct the emerging
air toward the windows ,
toward your upper body or
into the footwell . All inter-
mediate settings are also available. In
the setting, there is a low flow of air
onto the windows to keep them free of
condensation.
Air supply
You can control the emerging
air's flow rate through an infi-
nitely-variable range. The
heating and ventilation
become more and more effective as the
air supply settings are increased. In the
"0" setting, the blower and climate con-
trol are switched off and the outside air
supply is blocked.
Rear window defroster
The indicator lamp comes
on to indicate that the rear
window defroster is in operation. The
rear window defroster switches off
automatically.
Cooling
The air conditioning cools
and dehumidifies the
incoming air before reheating it to the
selected temperature. Depending on
the weather, the windshield may fog
over briefly when the engine is started.
You can reduce condensation forming
on the windows by switching on the air
conditioning.
Condensation forms in the air
conditioning system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
You can respond to
unpleasant odors in the sur-
rounding environment by using this
mode to temporarily suspend the flow
of outside air into the vehicle's interior.
The system then recirculates the air
currently within the vehicle.
If your vehicle is equipped with a multi-
function steering wheel
featuring a
recirculated-air button then you can
also select the recirculated-air mode
from this location (refer to page 22).
If the windows should fog over in
the recirculated-air mode, switch
the recirculated-air mode off and
increase the air supply as required.<

Automatic climate control
*
Tips for pleasant drivingUse the automatic system, that is,
press AUTO button 6. Select an interior
temperature that you find comfortable.
Detailed setting options are described
for you in the following section.
Your BMW center can program
the settings of your vehicle in such
a manner that, when you unlock the
vehicle with your individualized key,
your own personalized setting for the
automatic climate control is initiated.< Automatic air distribution
The AUTO program
assumes the adjustment of
the air distribution and the air supply for
you and also adapts the temperature to
external influences (summer, winter) to
meet preferences you can specify.
Individual air distribution
You can cancel the AUTO
program by selecting
specific distribution patterns
to suit your own individual
requirements. While the
AUTO program is then deactivated, the
automatic airflow control remains in
operation. The system directs air to the
windows , the upper body and
into the footwells . You can reacti-
vate the automatic air distribution mode
by selecting the AUTO button.
Temperature
You can make individual
temperature settings on the
driver's side or the front
passenger side. Your selection appears
in display 7. The numbers that appear
in the display are reference figures for
interior temperature. We recommend a
setting of 72 7 (22 6) for a congenial
interior climate, even when the air con-
ditioner is in operation. When you start
the vehicle, the system ensures that the
selected temperature is achieved as
quickly as possible. It then maintains
this temperature, regardless of the
season.
Air supply
AUTO appears in
display 9, while the AUTO
program automatically controls the flow
of incoming air, refer to overview on
page 109. You can use "+" and "Ð" to
vary the airflow. When your setting is
displayed by bars, the automatic airflow
is switched off. Automatic air distribu-
tion maintains its setting. You can reac-
tivate the automatic airflow by pressing
the AUTO button.
When you press "Ð " during operation at
minimum blower speed all displays are
canceled: the blower, heating and air
conditioner are switched off. The out-
side air supply is deactivated. By
pressing any button of the automatic
climate control (except the MAX
button 16), you can switch the system
back on.
To defrost windows and remove
condensation
This program quickly
removes ice and conden-
sation from the windshield and the side
windows.

Air conditioning
The air is cooled and
dehumidified and Ð
depending on the temperature setting Ð
warmed again when the air conditioning
is switched on. Depending on the
weather, the windshield may fog over
briefly when the engine is started. You
can reduce condensation forming on
the windows by switching on the air
conditioning.
Condensation forms in the air
conditioning system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Maximum cooling
With the engine running
this program provides
maximum cooling at outside tempera-
tures above approx. 41 7 (5 6).
60 7 (16 6) appears in the tempera-
ture display 9, and the system reverts to
the recirculated-air mode while simulta-
neously providing maximum airflow
through the vent outlets only. That is
why you need to keep these open if you
select this program.
Automatic recirculated-air
control (AUC)
You can respond to
unpleasant external odors
by temporarily stopping the flow of out-
side air. The system then recirculates
the air currently within the vehicle.
Press the button repeatedly to run
through the following control sequence:
>Indicator lamps off: outside airflow
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air cur-
rently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right-hand indicator lamp on: the
flow of external air into the vehicle is
permanently blocked. The system
then recirculates the air currently
within the vehicle.
If you have a multifunction steering
wheel with the recirculated-air button
(refer to page 22), you can also use it to
switch between "Off" and the recircu-
lated-air mode or AUC and the recircu-
lated-air mode.
If the windows should fog over in
the recirculated-air mode, switch
the recirculated-air mode off and
increase the air supply as required.< Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.
