Electronic vehicle immobilizer The key to securityYour BMW is equipped with a passive
anti-theft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of the vehicle to theft
by making it impossible to start the en-
gine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for individ-
ual keys (in the event of loss, for in-
stance). A deactivated key can no
longer be used to start the engine.

LOCK
463de042
How the electronics workAt the heart of this system is an elec-
tronic chip that is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, vehicle-specific signals with
the electronic circuitry in the key. The
system will not release the ignition, fuel
injection and starter unless it recog-
nizes an "authorized" key.
Force applied to the key can dam-
age the integrated electronic cir-
cuitry. A damaged key can no longer be
used to start the engine.<

0 Steering lock engaged The key can only be inserted and
removed in this position.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
you hear the lock engage.
If the key is not removed, an acoustic
signal chimes after the driver's door has
been opened.
Vehicles with automatic
transmission:
Move the selector lever from position P
only after the engine is running (ignition
key in position 2).
In order to turn the key back to position 0
or to remove it, move the selector lever
into position P first (Interlock).<462de195
1 Steering lock disengaged Turning the steering wheel slightly to
the right or left often makes it easier to
turn the key from 0 to 1.
Individual electrical devices are ready
for operation.2 Ignition onAll electrical equipment and accesso-
ries are available for use.3 Starting the engine
Vehicles with manual
transmission:
Step on the clutch when starting the
vehicle. A lockout prevents the engine
from starting if the clutch is not de-
pressed.c
Before starting>Engage parking brake
>Ensure that the transmission selector
is in "Neutral" (or "Park" if vehicle is
equipped with automatic transmis-
sion)
>Manual transmission: Depress the
clutch pedal
>Automatic transmission: Depress the
footbrake.
Never allow the engine to run with
the vehicle standing in an en-
closed area. The exhaust gases contain
carbon monoxide, an odorless and col-
orless, but highly toxic gas. Breathing
the exhaust gases poses an extreme
health risk, and can lead to uncon-
sciousness and death.
Do not leave the car unattended with
the engine running. An unattended ve-
hicle with a running engine represents a
potential safety hazard.<
>Start the engine. Do not press the
accelerator pedal.

Starting the engine Switching off the engine
Do not operate the starter too
briefly, but not longer than
approx. 20 seconds. Release the igni-
tion 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, drive off
immediately at a moderate engine
speed.<
Should the engine fail to start on the
first attempt, e.g. if it is very hot or cold:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold start at extremely low tempera-
tures, from approx. + 57 (– 156)
and at elevations above 3300 feet
(1000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
>Press the accelerator pedal halfway
down while engaging the starter.
Turn the ignition key to position 1 or 0.
Do not pull the ignition key out of a
rolling vehicle, otherwise the igni-
tion switch could lock and it is impossi-
ble to steer the vehicle.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces, as placing the lever in 1st gear or
reverse may not provide adequate re-
sistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park".<

Automatic transmission with Steptronic
*
You have the option of driving a normal
automatic transmission or switching to
manual.
Whenever you shift the selector lever
out of position D toward the left and
into the M/S gate, the automatic trans-
mission's sports-emphasized shift pro-
gram activates. As soon as you even
begin to move the selector lever in the
direction "+" or "–", Steptronic shifts the
gear and manual operation becomes
active. Whenever you want to use auto-
matic again, just shift the selector lever
toward the right to position D.
The Steptronic automatic transmission
is equipped with ATC (Adaptive Trans-
mission Control). ATC reacts with preci-
sion to your individual driving style and
the current driving conditions. This is
the reason why various shift programs
are used.
For details concerning ATC, please
refer to the chapter "Advanced Tech-
nology" on page 160.
Selector lever positions
P R N D M/S + –
Starting the engineThe engine can only be started in
selector lever positions P ("Park") or
N ("Neutral").Range selectionA lock prevents inadvertent shifts into
some selector lever positions. To re-
lease the shift-lock mechanism, press
the button on the front of the shift knob
(arrow).462de209
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral," depress the footbrake in or-
der to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. Otherwise the vehicle will "creep"
when a drive position is engaged.<
Before leaving the vehicle with the
engine running, shift the selector
lever to the "Park" or "Neutral" position
and apply the parking brake. The vehi-
cle will move if this is not done. Do not
leave the car unattended with the en-
gine running. An unattended vehicle
with a running engine represents a po-
tential safety hazard.<

D Drive (automatic shift program)This position is designed for driving un-
der all normal operating conditions. All
forward gears are available, the Adap-
tive Transmission Control (ATC) is fully
operational."Kickdown" (automatic downshift)In the "Kickdown" mode, you achieve
maximum performance.
To activate this mode, depress the ac-
celerator pedal beyond the full-throttle
position, at which a resistance point
must be overcome.
M/S Manual operation and
Sport programShifting from D into M/S activates the
Sport program and indicates SD in the
gear indicator. This position is recom-
mended in the event a performance-
oriented driving style is desired.
At the slightest touch, the automatic
transmission shifts out of the Sport pro-
gram into manual operation.
Whenever you start to move the selector
lever forward in the "+" direction, the
transmission upshifts; moving it back-
ward in the direction of "–", shifts it
downward. M1 to M5 appear in the gear
indicator.462de210
The ATC will carry out upshifting and/or
downshifting only at the appropriate
number of RPMs and speed, e. g.
downshifting will not occur if the engine
speed is too high. The desired, then the
actual gear, briefly show up in the in-
strument cluster.
To accelerate quickly in the man-
ual mode, e. g. to pass, downshift
to manual or kickdown.<
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.

Automatic transmission with Steptronic
*
The Steptronic will "think" for you in the
following situations:
>In order to keep the engine from
overrevving, it will automatically shift
into the next higher gear shortly be-
fore the governed speed.
>If you do not do anything to interfere,
it will automatically downshift at
lower speeds.
>In kickdown, it will downshift into the
lowest gear possible, depending on
the engine speed.

If the indicator lamp comes on,
there is a malfunction in the
transmission system.
Bring the vehicle to a stop, select trans-
mission position "P", set 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 perfor-
mance has been restored. Drive off
normally.
If the indicator lamp does not go out, all
selector lever positions can still be se-
lected; however in the forward positions
the vehicle has limited performance as
it drives only in 3
rd and 4
th gear.
If this happens, avoid extreme engine
loads and consult the nearest authorized
BMW center.
Do not carry out any work on the
car in the engine compartment
without first making sure that the selector
lever is in position P or N, and that
the parking brake has been set.<

Fuel gauge Temperature gauge When you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
Once the indicator lamp begins to light
up continuously, there are still approx.
2.1 gallons (8 liters) of fuel in the fuel
tank.
Tank capacity: page 173.
If the tilt of the vehicle varies, e.g.,
when you are driving in mountainous
areas, this may cause the needle to
fluctuate slightly.
Please refuel early, as driving to
the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<462us020
