Reporting safety defects
The following only applies to vehicles
owned and operated in the US.
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 noti-
fying BMW of North America, LLC, P.O.
Box 1227, Westwood, New Jersey 07675-
1227, Telephone (800) 831-1117.
If NHTSA receives similar complaints, it
may open an investigation, and if it finds
that a safety defect exists in a group of
vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot
become involved in individual problems
between you, your dealer, or BMW of North
America, LLC.
To contact NHTSA, you may either call the
Auto Safety Hotline toll-free at 1-800-424-
9393 (or 366-0123 in Washington, D.C.
area) or write to: NHTSA, U.S. Department
of Transportation, Washington, D.C.
20590. You can also obtain other informa-
tion about motor vehicle safety from the
Hotline.

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

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.

>When mounted at an angle, the tow bar
will exert lateral forces, tending to push
the vehicle sideways.
Secure the tow bar on the tow fitting
only. Otherwise damage could result
on other vehicle parts.<
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 on the
tow fitting only. Otherwise damage could
result on other vehicle parts.<
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
automatic transmission.
Jump-starting, refer to page 184.<
Only tow-start vehicles with a catalytic
converter with the engine cold. It is better
to jump-start the engine, refer to page 184.
