If you believe that your vehicle has a defect
which could cause a crash or could cause injury
or death, you should immediately inform the
National Highway Traffic Safety Administration
(NHTSA) in addition to notifying BMW of North
America, LLC, P.O. Box 1227, Westwood, New
Jersey 07675-1227, Telephone (800) 831-

If NHTSA receives similar complaints, it may

other information about motor vehicle safety
from the Hotline.

Driving
56 Vehicles with manual or SMG transmission:
When parking on inclines, engage the hand-
brake, as even engaging the first or reverse gear
might not under certain circumstances secure
the vehicle against moving.
Vehicles with automatic transmission
*:
Engage selector-lever position P.<
To prevent corrosion and one-sided brak-
ing action, occasionally engage the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.<
Manual transmission
When shifting into 5th/6th gear, press the
selector lever toward the right, otherwise
an inadvertent shift into 3rd or 4th gear could
damage the engine.<
Reverse gear
Select only when the vehicle is stationary.
When pressing the gearshift lever to the left,
overcome some resistance.
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
electrohydraulic 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 Dynamic Driving Control
page59
>Automatic downshifting and protection
against incorrect shifting even in sequential
operation
>Kick-down function in the Drive mode
>Acceleration assistant, refer to page59.
The SMG is operational in ignition key
position 2.
Selector-lever positions
The current selector-lever position is displayed
on the center console.
>R: Reverse gear
>N: Neutral, idle
>One-touch functions for Sequential mode:
+: manual upshifting
–: manual downshifting
>D: Drive mode
The transmission automatically shifts into
N if the driver's door is opened with the
engine running and neither the pedals, the shift
paddles nor the selector lever are operated.
This is indicated by an acoustic signal and the
flashing display N in the instrument cluster.<

Automatic transmission with
Steptronic*
In addition to the fully automatic mode, you can
also shift manually with Steptronic, refer to
page58.
Selector-lever positions
P R N D M/S + –
Displays in instrument cluster
P R N D DS M1 to M6
The selector lever position is indicated, and in
the manual mode, the gear currently engaged.
Changing the selector-lever positions
An interlock prevents inadvertent gearshifts
into selector-lever positions R and P. To cancel
the interlock, press the button on the front of
the selector lever knob, refer to arrow.
Shiftlock
Press the brake pedal before shifting out of P
or N; the shift command will not be executed
unless the brake is applied.
To prevent the vehicle from creeping after you
select a driving position, maintain pressure on
the brake pedal until you are ready to start.To prevent the vehicle from rolling,
always select selector-lever position P
and engage the handbrake before leaving the
vehicle with the engine running.
Never leave an unattended vehicle with the
engine running, as such a vehicle represents a
potential safety hazard.<
P Park
Select only when the vehicle is stationary.
The rear wheels are locked.
R Reverse
Select only when the vehicle is stationary.
N Neutral
Engage in car washes, for example. The vehicle
can roll.
D Drive, automatic position
Position for normal vehicle operation.
All forward gears are available.
Under normal operating conditions, fuel con-
sumption is lowest when driving in position D.
Kick-down
The kick-down mode provides maximum accel-
eration:
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 shifting slot M/S:
The sport program is activated and DS appears
in the instrument cluster. This position is

recommended for a performance-oriented driv-
ing style. It is engaged automatically when the
Dynamic Driving Control is activated, see
below.
When the selector lever is briefly moved for-
ward or back, the manual mode is activated and
the Steptronic shifts gear. The instrument clus-
ter shows M1 through M6.
Upshifts and downshifts are executed only
when they will result in a plausible combination
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 position D.
Dynamic Driving Control
The Dynamic Driving Control makes it possible
for your BMW to react in an even more perfor-
mance-oriented manner at the push of a button:
>The engine responds more spontaneously
to accelerator pedal movements.
>Cruise control:
The stored speed is reached more quickly
when it is requested.
Additionally with SMG:
>Gearshifts are faster.
>The engine speed range is used optimally in
the Drive mode.
With automatic transmission:
>The Sport program is activated.
Activating system
In ignition key position 2, press the SPORT but-
ton.
The LED in the button lights up and SPORT is
displayed in the instrument cluster.
Deactivating system
>Press the SPORT button again or
>engage reverse gear or
>switch off the engine.
The LED in the button and SPORT in the instru-
ment cluster go out.
Acceleration assistant with SMG
The acceleration assistant enables optimized
vehicle acceleration at racing car level on road
surfaces with good adhesion when starting off.
Do not use the acceleration assistant too
often, as otherwise components will wear
prematurely.<
1.Activate the Dynamic Driving Control.
2.Press the DTC button, refer to page82, for
longer than three seconds.
3.Press the accelerator pedal down fully:
Kick-down. The ideal starting-off engine
speed is set.
To maintain driving stability, do not deac-
tivate DSC if at all possible.<

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fitting only.
Otherwise to other vehicle parts could
result.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Secure the tow rope to the tow fitting only. Oth-
erwise damage to other vehicle parts could
result.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a load bed.
Do not lift vehicle by tow fitting or body
and chassis parts, as otherwise damage
may result.<
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission.
Jump starting, refer to page186.<
Only tow-start vehicles with a catalytic con-
verter with the engine cold. It is better to jump
start the engine, refer to page186.
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Turn the ignition key to position 2.
3.Shift into 3rd gear, vehicles with SMG, see
below.4.Have the vehicle tow-started with the clutch
pedal completely depressed and slowly
release the clutch. After the engine starts,
immediately depress the clutch pedal com-
pletely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
Vehicles with SMG Sequential manual trans-
