Automatic transmission with Steptronic
*
You may drive your vehicle as with a
typical automatic transmission, but you
may also shift manually.
When you move the selector lever to
the left from position "D" and into the
M/S shift level, the performance-ori-
ented shift programs of the automatic
transmission are activate. As soon as
you move the selector lever in the "+" or
"–" direction, Steptronic changes the
gear and the manual mode is active. If
you wish to utilize automatic shifting
once again, move the selector lever to
the right and into the D position.
The automatic transmission of your
BMW is equipped with an Adaptive
Transmission Control (ATC). This sys-
tem reacts with precision to your indi-
vidual driving style and the current driv-
ing conditions. Different shift programs
are utilized to achieve this.
For details concerning ATC, please re-
fer to the chapter describing "Advanced
technology" on page 184.
Selector lever positions
P R N D M/S + –
Starting engineThe engine can only be started in selec-
tor lever positions P ("Park") or N ("Neu-
tral").380us667
Range selectionA detent prevents inadvertent shifts into
some selector lever positions. To re-
lease the shift-lock mechanism, press
the button on the front side of the se-
lector handle (arrow).
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 (shift-lock).
Hold the footbrake down until starting
off. The vehicle will otherwise "creep"
when a drive position is engaged.< 380de211

Before exiting the vehicle when
the engine is running, place the
selector lever in the "Park" or "Neutral"
position and apply the parking brake. If
you do not, the vehicle can move.
Do not leave the car unattended with
the engine running. An unattended ve-
hicle with a running engine represents a
potential safety hazard.<
P - ParkSelect "Park" only when the vehicle is
stationary. The transmission locks to
prevent the rear wheels from turning.R - ReverseSelect "Reverse" only when the vehicle
is stationary.N - NeutralSelect "Neutral" only if your journey is
interrupted for a longer period.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.
Press the accelerator pedal past the in-
creased resistance point at the full-
throttle position.
M/S - Manual mode and
Sport ProgramWhen you change from "D" to M/S, the
Sport program is activated. This is indi-
cated by "D S" in the gear display. This
position is recommended if your driving
style is performance-oriented.
With the first brief touch, the automatic
transmission shifts from the Sport pro-
gram to manual mode.
When you move the selector lever for-
ward in the "+" direction, the transmis-
sion shifts up. When moved back in the
"–" direction, the transmission shifts
down.
Depending on the version, "1 to 5" or
"M1 to M5" appears in the gear display.380de659

The ATC will execute upshifts or down-
shifts only at appropriate engine and
road speeds. For example, the trans-
mission does not shift down when the
engine speed is too high. The selected
gear will appear briefly in the instrument
cluster, followed by the current gear.
In the manual mode for rapid ac-
celeration – when passing, for ex-
ample – manually or a shifting down to
the kickdown point.<
You can only change from M/S to the
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 au-
tomatically to the next higher gear
shortly before the RPM cutoff point
>At low speeds, the transmission shifts
down automatically - you do not have
to act
>In the kickdown mode, the transmis-
sion shifts down to the lowest gear
which is possible, depending on the
engine speed.
Electronic transmission control
moduleIf the "TRANS. FAILSAFE PROG" mes-
sage appears in the Check Control,
there is a malfunction in the transmis-
sion system.
You can still place the selector lever in
all positions. However, it is possible
that not all gears are available for the
vehicle's forward drive.
If this happens, avoid extreme engine
loads and consult the nearest autho-
rized 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.<
For towing, tow-starting and jump-
starting, refer to pages 179, 180.

Cruise controlTo cancel the cruise controlWhen the system is activated, press
and hold button 4. The indicator lamp
stays on. You can use the cruise control
again as desired.
In addition, cruise control is canceled
automatically:
>When you apply pressure to the
brake pedal
>If the automatic transmission selector
lever is moved from "D" to "N"
>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).<

Park Distance Control (PDC)
*
The PDC assists you when you are
parking. Acoustic signals warn you
of the distance to an obstacle. In addi-
tion, four ultrasonic sensors in each the
front and rear bumpers measure the
distance from the nearest object. The
monitoring range for the four front sen-
sors and that of the two rear corner
sensors ends approx. 2 feet (60 cm)
beyond the respective bumper. The two
center sensors cover a distance of
approx. 5 feet (1.50 m).380de619
The system starts to operate automati-
cally about one second after you move
the selector lever to "R" when the igni-
tion key is in position 2. It is similarly
deactivated when you move the selec-
tor lever position from the "R" position.
The indicator lamp in the button (arrow)
comes on to signal the active status.
Manual activation/deactivation is possi-
ble using the button in the center
console (arrow) (indicator lamp comes
on/goes out). The system deactivates
once the vehicle travels approximately
160 ft (50 m) or exceeds a speed of
about 18 mph (30 km/h). It must then be
switched on again as desired.
Acoustical signalsThe distance to an obstruction in the
front is indicated by a higher interval
tone, while the distance to an obstruc-
tion in the rear is indicated by a deeper
tone. As the distance between vehicle
and object decreases, the intervals be-
tween the tones become shorter. A
continuous tone indicates the presence
of an object less than 1 ft. (30 cm)
away.
The warning signal is canceled after ap-
prox. three seconds if the distance to
the obstruction remains constant during
this time (if you are moving parallel to a
wall, for instance).
System malfunctions are indicated by a
short, continuous tone and a flashing
indicator lamp (indicator lamp only
when the system is activated by shifting
the transmission into "R").
Switch the system off and consult an
authorized BMW center to have the
problem corrected.

Integrated Universal Remote Control
*
The conceptThe Integrated Universal Remote Con-
trol replaces up to three hand-held
transmitters of different devices such as
garage-door openers, alarm systems,
or door locking systems. The Integrated
Universal Remote Control recognizes
and "learns" the transmitted signal of
each of the original hand-held transmit-
ters.
The signal of an original hand-held
transmitter can be programmed on one
of the three channel keys. Following
that, each of the devices can be actu-
ated with the appropriately-program-
med channel key. Transmission of the
signal is signaled by the indicator lamp.
If the vehicle is sold, the memory of the
channel keys should be cleared as de-
scribed on page 110.
During programming and before
every remote actuation of a pro-
grammed device by the Integrated Uni-
versal Remote Control, check to be
sure that there are no persons, animals
or objects within the actuation range of
the device in order to prevent possible
injuries or damage. Also, comply with
the safety precautions of the original
hand-held transmitter.<
To Canadian residents:
During programming, your hand-
held transmitter may automatically stop
transmitting after two seconds, which
may not be long enough to program the
BMW Universal Transmitter. If you are
programming from one of these hand-
held transmitters, the Universal Trans-
mitter's light may begin to flash in a se-
ries of double-blinks. If this occurs,
continue to hold the button on the Uni-
versal Transmitter while you reactivate
your hand-held transmitter. You may
have to repeat this function several
times while programming.<
Before programming, read the
"User information" section on
page 110.<
Original hand-held transmitter
If this symbol is present on the
packaging or in the instructions
of the original hand-held trans-
mitter, it may be assumed that this
hand-held transmitter is compatible
with the Integrated Universal Remote
Control.
Checking for the conversion codeTo determine whether the original
hand-held transmitter is provided with a
conversion-code system, you may ei-
ther read the instructions for the original
hand-held transmitter or program a
channel key as described on page 109
(left-hand column under "Program-
ming").
Then press and hold the programmed
channel key of the Integrated Universal
Remote Control. If the indicator lamp of
the Integrated Universal Remote Con-
trol flashes for two seconds and then
comes on steadily, the original hand-
held transmitter is provided with a con-
version-code system. With a conver-
sion-code system, program the channel
keys as described on page 109 (right-
hand column under "Programming a
hand-held transmitter with conversion
code").
If you have additional questions,
please consult your BMW center
or call 1-800-355-3515.<

Driving notes
Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires
and road surface. This phenomenon is
referred to as aquaplaning or hydro-
planing. It is characterized by a partial
or complete loss of contact between
the tires and the road surface. The ulti-
mate results are loss of steering and
braking control.
Driving through water:
Do not drive through water more than
1 foot (30 cm) deep. In water of this
depth, drive only at walking speed, oth-
erwise damage to the engine, the elec-
trical system and the transmission can
occur.
Rear parcel tray:
Do not use the rear parcel tray to store
heavy or bulky objects. They could
pose a danger to the occupants during
braking maneuvers.
Clothes hooks:
Hang items of clothing from the hooks
so that they will not obstruct the driver's
vision. In order to avoid personal inju-
ries during braking maneuvers, do not
hang heavy objects on the hooks.<

Catalytic converterThe catalytic converter reduces harmful
exhaust emissions, and is designed for
use with unleaded fuel only.
Even minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system's
oxygen sensor.
To ensure efficient, trouble-free engine
operation and avoid potential damage:
>Be sure to comply with the scheduled
maintenance requirements
>Fill the fuel tank well before it is
empty
>If you have problems starting the en-
gine, use jumper cables (you cannot
tow-start the vehicle with an auto-
matic transmission)>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never let the engine run with any of
the spark plug cables disconnected.Be sure to comply with the in-
structions above to prevent un-
burned fuel from reaching the catalytic
converter. Otherwise there is danger of
overheating and damage to the cata-
lytic converter.
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Heat shields
are installed adjacent to some sections
of the exhaust system. Never remove
these shields; do not apply undercoat-
ing to their surfaces. When driving,
standing at idle, and parking the vehi-
cle, take care to avoid contact between
the exhaust system and flammable ma-
terials (grass, hay, leaves, etc.). Such
contact could lead to a fire, resulting in
personal injury and property damage.<

Disc brakesDriving notesWhile driving in wet conditions and in
heavy rain, it is a good idea to apply
light pressure to the brake pedal every
few miles. Watch traffic conditions to
ensure that this maneuver does not en-
danger other road users. The heat gen-
erated in this braking process helps 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 129).
Extended or steep mountain descents
do not necessarily have to lead to re-
duced braking efficiency; downshift to a
gear in which only minimal periodic
brake applications are required - move
the selector lever to the appropriate
lower range.
You can continue to increase the brak-
ing effect of the engine by selecting a
lower gear - you can select transmis-
sion ranges as low as position 2 for ex-
treme conditions.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 the vehicle by applying more
substantial force on the pedal (watch
for following traffic!) and then pausing
before repeating the application. This
staggered braking technique allows the
brakes to cool in the intervals between
active braking phases, preventing over-
heating and ensuring that full braking
capacity remains available at all times.
Do not coast with the transmission
selector lever in neutral. Do not
drive with the engine shut off. The en-
gine provides no braking effect when
the transmission is in neutral, and there
is no power-assist for braking or steer-
ing when the engine is shut off.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator and brake ped-
als and obstruct their movement.<
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
warning lamp comes on with a
yellow light. Conventional brak-
ing efficiency is available with-
out limitations.
Have the system checked and
repaired at your BMW center as soon
as possible.
For "Information for your safety"
covering the ABS system, refer to
page 125. This information also gener-
ally applies for DBC.<
