SMG Sequential manual
transmission and automatic
transmission
Your BMW is equipped with the conve-
nience starting feature. Here, it is sufficient
to turn the ignition key only briefly to posi-
tion 3 'Start engine' and to let go of it right
away. The system responds by automati-
cally engaging the starter for a certain
period and allowing it to run until the engine
starts, after which it then disengages auto-
matically.
SMG Sequential manual
transmission
1.Press the brake pedal
2.Engage selector-lever position N
3.Start the engine.
If the engine does not start, engage
the last gear selected again, refer to
instrument cluster display, and then
engage selector-lever position N.<
Automatic transmission with
Steptronic
1.Press the brake pedal
2.Engage selector-lever position P or N
3.Start the engine.
Switching off engine
Do not remove the ignition key while
the vehicle is rolling, as otherwise the
steering wheel lock would engage while
steering.
When leaving the vehicle, remove the igni-
tion key and lock the steering.
When parking on a downhill incline, apply
the handbrake, as otherwise the vehicle
could roll away.<
Manual transmission
1.Turn the ignition key to position 1 or 0
2.Engage first or reverse gear.

engaged on stopping the engine.
Automatic transmission with
Steptronic
1.Engage selector-lever position P
2.Turn the ignition key to position 1 or 0.
Handbrake
The handbrake is primarily intended to pre-
vent the vehicle from rolling while parked;
it brakes the rear wheels.
Indicator lamp
The indicator lamp lights up, and an
acoustic signal also sounds when
starting off. The handbrake is
engaged.
Indicator lamp for Canadian mod-
els.
Engaging
The lever locks into place automatically;
the indicator lamp in the instrument cluster
lights up as of ignition key position 1.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to engage the
handbrake while the vehicle is in motion,

Driving
56 do not pull it too strongly. In doing so, con-
tinuously press the button of the handbrake
lever.
Strong application of the handbrake can
lead to overbraking of the rear axle and
associated 'fishtailing' of the vehicle rear
end.
The brake lamps do not light up when the
handbrake is engaged.
Vehicles with manual or SMG transmission:
When parking on inclines, engage the
handbrake, as even engaging the first or
reverse gear might not under certain cir-
cumstances secure the vehicle against
moving.
Vehicles with automatic transmission:
Engage selector-lever position P.<
To prevent corrosion and one-sided
braking action, occasionally engage
the handbrake lightly when the vehicle is
slowly coming to a standstill if the traffic
conditions are suitable.<
Manual transmission
While shifting gear in the 5th/6th gear
level, press the gearshift lever to the
right, as otherwise engine damage could
occur from inadvertently engaging a gear in
the 3rd/4th gear level.
On inclines, do not hold the vehicle with the
clutch; use the handbrake. Otherwise there
is high clutch wear.<
Reverse gear
Select only when the vehicle is completely
stationary. When pressing the gearshift
lever to the left, overcome some resis-
tance.The backup lamps automatically switch on
in ignition key position 2.
SMG Sequential manual
transmission*
The concept
The SMG Sequential manual transmission
is an automated manual transmission in
which an electro-hydraulic system handles
the clutching and gear changes.
You operate the SMG using the selector
lever in the center console and two shift
paddles on the steering wheel.
It offers the following functions:
>Choice of manual or automatic mode:
Sequential mode or Drive mode
>Options of two drive programs:
Normal or Sport, refer to page 59
>Protection against incorrect gearshifts
and automatic shift down at minimum
engine speed, also in the Sequential
mode
>Kickdown function in the Drive mode
>Acceleration assistant, refer to
page 60.
The SMG is operational in ignition key posi-
tion 2.
Selector-lever positions
The current selector-lever position is dis-
played on the center console.
>R: Reverse gear
>N: Neutral, idle

N is automatically engaged if the
driver's door is opened with the
engine running and neither pedals, shift
paddles nor the selector lever are oper-
ated.
This is indicated by an acoustic signal and
the flashing display N in the instrument
cluster.<
Gear display
R N 1 to 6
The currently engaged gear is displayed, in
the Drive mode preceded by a D.
Shiftlock
Press the brake pedal before shifting out
of N; the shift command will not be exe-
cuted unless the brake is applied.
R Reverse
Select only when the vehicle is completely
stationary.
Sequential mode
After every engine start, as soon as the
selector lever is pushed to the right and the
brake pedal is pressed, the Sequential
mode is activated.
The gear is changed using the shift paddles
or selector lever.
Driving off is also possible in second gear,
e.g. when the roadway is icy.
D Drive mode
In the Drive mode, all forward gears are
shifted automatically.
To switch from Sequential to Drive mode:
Briefly press the selector lever to the right
towards D.
Kickdown:
For rapid acceleration, e.g. overtaking,
press the accelerator pedal as far down as
it will go: you achieve maximum accelera-
tion.
To switch back to the Sequential mode:
briefly press the selector lever back to the
right towards D or change the current gear
using the shift paddles or selector lever.
Start off quickly on slopes. Do not
hold the vehicle on a hill by applying
the throttle, but engage the handbrake
instead. Otherwise overheating can occur
in the area of the transmission.<
Gear changes
Using selector lever
>To shift up, briefly press the selector
lever towards +
>To shift down, briefly press towards —.
Using shift paddles on steering
wheel
>To shift up, pull one of the shift paddles
>To shift down, press.
In the following situations, the SMG in the

P Parking
Select only when the vehicle is completely
stationary. The rear wheels are blocked.
R Reverse
Select only when the vehicle is completely
stationary.
N Neutral
E.g. engage in car washes. The vehicle can
roll.
D Drive, automatic position
Position for normal vehicle operation.
All forward gears are available.
Under normal operating conditions, fuel
consumption is lowest when driving in
position D.
Kickdown
The kickdown mode provides maximum
acceleration:
Press the accelerator pedal beyond the
full-throttle resistance point.
M/S manual operation and
Sport program
Move the selector lever from position D to
the left into gearshift gate M/S:
The sport program is activated and DS
appears in the instrument cluster.
This position is recommended for a perfor-
mance-oriented driving style. It is engaged
automatically when the Dynamic Driving
Control is activated, see below.
When the selector lever is moved slightly
towards + or –, the Steptronic shifts gear
and manual operation is activated. The
instrument cluster shows M1 through M6.Upshifts and downshifts are executed only
when they will result in a plausible combi-
nation of engine and vehicle speed; thus,
for example, a downshift that would cause
the engine to overrev will not be executed
by the system. The selected gear appears
briefly in the instrument cluster, followed by
the current gear.
To use the automatic function again, move
the selector lever to the right into posi-
tion D.
Malfunction
The warning lamp lights up and a
message appears on the Control
Display. There is a malfunction in
the transmission system. Avoid heavy
loads.
While it will remain still possible to move
the selector lever to any desired position,
the transmission will revert to operation in
its default mode with only a limited number
of forward gears.
Have the system checked as soon as pos-
sible.
Towing, refer to page, 185, jump-starting,
refer to page 185.
Dynamic Driving Control
The Dynamic Driving Control makes it pos-
sible for your BMW to react in an even more
sports-oriented manner at the push of a
button:
>The engine responds more spontane-
ously to accelerator pedal movements
>The steering conveys a feeling of even
better contact with the road surface
>Cruise control:
The stored speed you call up is reached
more quickly.
Additionally with SMG:
>Gearshifts are faster
>The engine speed range is used opti-
mally in the Drive mode.
With automatic transmission:
>The Sport program is activated.

Break-in procedures
To ensure that your vehicle continues to
provide optimized economy of operation
throughout an extended service life, we
request that you devote careful attention to
the following section.
Engine and differential
Up to 1,200 miles/2,000 km:
You should attempt to vary both vehicle
and engine speeds. Until the break-in
period has been completed, you should
also refrain from exceeding an engine
speed of 4500 rpm or a driving speed of
100 mph/160 km/h.
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kickdown mode during
these initial miles.
Once you have driven 1,200 miles/
2,000 km, the engine and vehicle speeds
can be gradually increased.
SMG Sequential manual
transmission
Do not use the acceleration assistant dur-
ing the break-in period, refer to page 60.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period. Therefore, drive reservedly
during the first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve opti-
mized contact and wear patterns between
brake pads and rotors.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of
approx. 300 miles/500 km. During this
break-in period, engage the clutch gently.
After component replacement
You should also comply with these break-in
procedures should the components men-
tioned above need to be replaced at a later
point.
General driving notes
Hot exhaust system
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to vari-
ous sections of the exhaust system, and
never apply undercoating to them. When
driving, standing at idle and while parking,
take care to avoid possible contact
between the hot exhaust system and any
highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead
to a fire, and with it the risk of serious prop-
erty damage as well as personal injury.<
Parking vehicle
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into a car wash
Fold in the exterior mirrors manually, as
otherwise they could be damaged due to
the width of the vehicle.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires and
