Sequential M gearbox* SMG IIThe warning stops after approx.
10 seconds. If you move the selector
lever into a forward or reverse position
during this time, a gear is automatically
engaged.
The SMG II has no park position
for securing the vehicle against
rolling.
The ignition key can be removed in any
selector lever position.<
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not sufficiently
secure the vehicle against rolling.<
Display in instrument clusterThe selector lever position, currently
engaged gear and selected driving
program are displayed in the instrument
cluster.
1 Engaged gear
2 Selected driving program
(corresponds to the number of illumi-
nated fields), refer to page 64
3 Tapping the selector lever to the right
switches over into the displayed shift
mode
4 "A" indicates an activated automated
mode.
R Ð Reverse positionOnly engage with the vehicle stopped
or at low speed, e.g. for "rocking free"
in deep snow.0 Ð Position 0Always engage before starting the
engine.
If the driving situation requires, e.g.
when downshifting on slippery roads,
the SMG II automatically disengages
and reengages the clutch, i.e. it is not
necessary to manually engage
position 0. S Ð Sequential modeIn the sequential mode all forward
gears are to be shifted by the driver.
Changeover from automated to
sequential mode:
>Tap the selector lever to the right
toward "S"
or
>change gears with the selector lever
or the shift paddles on the steering
wheel.
You do not need to reduce the throttle
for shifting.

Sequential M gearbox* SMG IIShifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right
paddle "+"
>To downshift, briefly pull the left
paddle "Ð."
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW
center.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward "+"
>To downshift, push the selector lever
forward "Ð".
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually down-
shifting.
In the following situations the SMG II
helps you "think" in the sequential
mode:
>Upshifts and downshifts are only
executed when the new gear will
provide a suitable combination of
vehicle and engine speed, i.e., down-
shifts that would cause the engine to
overrev will not be executed
>During a stop the gearbox is auto-
matically downshifted into the first
gear so that, e.g. before a traffic light,
it is only necessary to accelerate to
continue driving
>When the speed is reduced, the
gearbox is automatically down-
shifted shortly before a gear-depen-
dent minimum speed is reached
without you taking any action.
A Ð Automated modeEach time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
In the automated mode all forward
gears are automatically shifted.
Changeover from sequential to auto-
mated mode: tap the selector lever to
the right toward "A." Watch the display
in the instrument cluster, refer to
page 61.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely (kick-down). The gearbox
now downshifts in dependence on the
selected driving program.
Even in the automated mode, you can
help specify the shifting point: if a gear-
dependent minimum speed is
exceeded, you can upshift by slowly
reducing pressure on the accelerator
pedal. In the process, the respective
driving situation is detected by sensors
and taken into account.

The vehicle may roll slightly before
it is held by the gradient assis-
tance after releasing the footbrake.
Two seconds after the footbrake is
released, the vehicle begins to roll, as it
is no longer held with the gradient
assistance.<
The gradient assistance must be reacti-
vated before each use.
Indicator lamp
The transmission indicator lamp
in the instrument cluster goes
out after the engine is started.
>If it does not go out, or if it lights up
during driving, a fault has occurred.
The available functions may be
limited under certain circumstances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Shift lightsTo achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the
optimum shifting point shortly before
the maximum engine speed is reached.
1 When the maximum engine speed is
approached, yellow indicator fields
(shift lights) in the tachometer light up
consecutively to indicate the
approaching upshift time
2 Shift at the latest when the last indi-
cator field lights up red.Tire replacement, snow chainsFollowing a tire or wheel change and

Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
high temperatures, brake wear and
possibly even brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing, or hydroplaning, and can lead
to partial or complete loss of traction,
vehicle control and braking effective-
ness.
Driving through water:
Do not drive through water on the road
if it is deeper than 1 foot (30 cm), and
then only at walking speed. Otherwise,
the vehicle's engine, the electrical
systems and the transmission may be
damaged.
Rear parcel tray:
Never use it to store heavy or hard
objects, otherwise, occupants could be
injured if the vehicle is braked hard.
Clothes hooks:
When suspending clothing from the
hooks, be sure that they will not
obstruct the driver's vision. Do not hang
heavy objects on the hooks. If you do
so, they could cause personal injury
during braking or evasive maneuvers.<
The conceptThe Antilock Brake System (ABS) keeps
the wheels from locking while braking,
thereby enhancing active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply
maximum brake pressure ("panic
stop"). Since the vehicle maintains
steering responsiveness, you can
nevertheless avoid possible obstacles
with a minimum of steering effort.
Pulsation at the brake pedal combines
with sounds from the hydraulic circuits
to indicate to the driver that ABS is in
its active mode.Cornering Brake Control (CBC)CBC is an advanced engineering
design of the ABS. When braking while
cornering at high speed or braking
during high lateral acceleration, or
when braking during a lane change,
vehicle stability is improved and
steering response is enhanced.

Tire replacement Wheel and tire combinationsTire ageBMW recommends the replacement of
all tires after 6 years at the latest, even
if a tire life of 10 years is possible.
The date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4 101 means that the tire was
produced in the 41st week of the year
2001. Following wheel/tire changesFollowing wheel and/or tire replace-
ment you will need to reinitialize both
the Flat Tire Monitor and the sequential
M gearbox
* SMG II, refer to pages 65,
78.
The right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
BMW tests certain tire brands for each
tire size, classifies them as road-safe
and approves them. Consult your BMW
center for more information. Observe
any country-specific regulations, e.g.
on making a corresponding entry in the
vehicle documents.
The correct wheel and tire combi-
nation affects different systems
such as ABS, DSC, Flat Tire Monitor.
The function of these systems is
impaired if improper wheel and tire
combinations are used.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel and tire combination
following a flat tire as soon as possible.<
The use of rims and lug bolts that
do not meet the specifications of
the original factory-installed equipment
will affect the safe operation of your
vehicle and may cause an accident and
personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias-
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle
control.<
Storage Store tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against
contact with oil, grease and fuel.
