For your own safety
Use unleaded gasoline only. Fuels
containing up to 10% ethanol or
other oxygenates with up to 2.8% oxy-
gen by weight (i.e., 15% MTBE or
3% methanol plus an equivalent
amount of co-solvent) will not void the
applicable warranties with respect to
defects in materials or workmanship.
Field experience has indicated signifi-
cant differences in fuel quality (i.e., vol-
atility, composition, additives, etc.)
among gasolines offered for sale in the
United States and Canada. The use of
poor-quality fuels may result in drive-
ability, starting and stalling problems,
especially under certain environmental
conditions, such as high ambient tem-
perature and high altitude.
Should you encounter driveability prob-
lems that you suspect could be related
to the fuel you are using, we recom-
mend that you respond by switching to
a recognized high-quality brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Follow the relevant safety rules when
you are handling gasoline.

Automatic transmission4 - Sport programThis position is recommended if your
driving style is performance-oriented.3 and 2 - Shift limiterSelect this range when you wish to limit
gear changes (on steep uphill or down-
hill slopes, for instance). The transmis-
sion upshifts only as far as the selected
gear."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.Shift programsThe automatic transmission of your
BMW is equipped with the Adaptive
Transmission Control (ATC) as standard
equipment.When you select program A, the ATC
system automatically adapts to individ-
ual driving styles and road conditions to
provide optimal performance with the
selector lever at position D.
Because of this, the remaining selector
lever positions for forward driving are
only required in extreme situations such
as those listed in the description of po-
sition 2.
A - Adaptive programThis is the initial position that the trans-
mission selects at every start. In the po-
sitions for forward driving, the ATC
(Adaptive Transmission Control) auto-
matically selects the optimal gear from
different shift programs. To achieve
this, the system constantly adapts to
driver characteristics (such as a moder-
ate or performance-oriented driving
style), road condition factors (slick
roads or extreme slopes, for instance)
as well as the current driving situation
(winding roads or mountain travel, for
instance).
For details concerning ATC, please re-
fer to the chapter titled "Advanced
Technology" on page 184.
M – Manual programThis program is for driving in one gear
(4th gear when D has been selected).
The transmission then remains in the
selected gear both when underway and
when starting off. For instance, when
you make a steep ascent with the se-
lector lever in position 2, the transmis-
sion does not make undesired upshifts.
The same principle applies during oper-
ation on ice-covered roads: By placing
the selector lever in position 3 you can
move off gradually, and the transmis-
sion will also suppress subsequent
shifts into higher gears.Selector lever positionsPositions 4, 3 and 2 have the function of
enhanced control over shifting – control
which is desired and intentionally se-
lected.
The ATC also functions in these selec-
tor lever positions – of course with limi-
tations for gear selection imposed by
the lever position.

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.

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

Wiper/Washer systemon the traffic conditions. This is espe-
cially important under adverse weather
conditions.
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, re-
gardless of the weather.
You can leave the lever permanently in
position 1. It is then only necessary to
activate the rain sensor from ignition
key position 1 and up. To do this
>turn rotary dial 7 briefly or
>use either the automatic windshield
washer 5 or the automatic intensive
washer 6.
To modify the sensitivity of the rain
sensor:
Turn rotary dial 7.
Turn the rain sensor off in auto-
matic car washes.
If you do not, damage may occur if the
wipers switch on unintentionally.<
2 Normal wiper speedWhen the vehicle is stationary, the wip-
ers switch automatically to intermittent
wipe (not on vehicles with rain sensor).3 Fast wiper speedWhen the vehicle is stationary, the wip-
ers operate at normal speed (not on ve-
hicles with rain sensor).5 Automatic windshield washerThe 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.Headlamp washers
*
If they are on, the headlamps will also
be cleaned every fifth time you activate
the automatic windshield washer.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 142.
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 and the
windshield in the wiper sweep area are
defrosted automatically when the igni-
tion key is in position 2.
