Indicator and warning
lamps
Technology that monitors itself
Indicator and warning lamps that are iden-
tified by
+ are tested for proper functioning
whenever the ignition key is turned. They
each light up once for different periods of
time.
If a fault should occur in one of these sys-
tems, the corresponding lamp does not go
out after the engine is started or it lights up
again while the vehicle is moving. The indi-
cated pages provide information on what
measures to take.

Switching off the engine
Do not remove the ignition key while
the vehicle is still moving. If you did
so, the steering lock would engage when
the steering wheel is turned.
When you leave the vehicle, always remove
the ignition key and engage the steering
lock.
Always engage the parking brake when
parking on downhill roads.<
You can have an acoustic signal set
as a reminder that the ignition key is
still in the ignition switch after the driver's
door has been opened.<
Manual transmission
Turn the ignition key to position 1 or 0.
Automatic transmission
Place the selector lever in position P and
turn the ignition key to position 1 or 0.
Sequential manual gearbox SMG
If you turn the ignition key to position 1 or 0
with the selector lever in position R, or in
sequential mode, a gear automatically
remains engaged.
If you turn the ignition key to position 1 or 0
with the selector lever in neutral position N,
a warning tone and the flashing gear indi-
cator in the display remind you that the
vehicle is not secured against rolling.
The warning stops after approx. 9 seconds.
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not sufficiently secure
the vehicle against rolling.<

Driving
40 direction, the transmission shifts up. When
the lever is tapped in the – direction, the
transmission shifts down. M1 to M 5 appear
in the gear indicator.
The Adaptive Transmission Control ATC
executes upshifts or downshifts only when
the new gear will provide a suitable combi-
nation of engine and road speed, e.g. ATC
will not execute downshifts if the engine
speed is too high. The desired gear will
appear briefly in the instrument cluster, fol-
lowed by the actual gear.
If you are driving in the manual mode
and wish to accelerate rapidly, e.g. to
pass another vehicle, shift down manually
or with the kickdown function.<
Shifting from M/S to selector lever posi-
tions P, R and N is possible only by going
through position D.
Available indicators

Malfunction
If the indicator lamp comes on,
there is a malfunction in the trans-
mission system.
All of the selector lever positions can con-
tinue to be engaged; in the forward drive
positions, however, the vehicle will be
operating in the fourth gear only.
If this happens, avoid extreme engine loads
and consult the nearest BMW center.
Never work in the engine compart-
ment when a drive gear – forward or
reverse – is engaged. If you do so, the vehi-
cle could move. information beginning on page 94.
Sequential manual gearbox
SMG*
The concept
The sequential manual gearbox SMG is an
automated manual gearbox with which
clutching and shifting is assumed by an
electro-hydraulic system.
The SMG is operated via two shift paddles
on the steering wheel and the selector lever
in the center console.
It offers the following functions:
>Sequential mode: manual mode
>Drive mode: automated mode
>Ability to choose between two different
driving programs: Standard, Sport,
refer to Dynamic Driving Control
>Operating safety through protection
against misshifting
>Automatic upshifts and downshifts in
the drive mode
>Automatic downshifts at minimum
engine rpm
>Kickdown function in the drive mode
>Acceleration assistant.
Selector lever positions
The current selector lever position is shown
by a light-emitting diode on the center con-
sole.
R: Reverse
N: Neutral

Forward position with one-touch functions:
Sequential mode
+:manual upshifting
—:manual downshifting
D: drive mode.
The SMG is ready for operation in ignition
key positions 2 and 3.
The gearbox is automatically taken
out of gear if the driver's door is
opened while the engine is running and the
driver does not actuate the pedals, the shift
paddles or the selector lever.
This is accompanied by an acoustic signal
and the flashing gear indicator.
The gear indicator in the instrument cluster
displays N.
A driving position can only be engaged
when the driver's door is closed.
When the vehicle is unlocked, a buzzing
sound in the area of the transmission indi-
cates that the system is ready to operate.<
Shiftlock
For your safety, it is only possible to
engage a driving position from selector
lever position N when the footbrake is
depressed.
Please keep in mind while driving
When driving off on inclines, drive
smoothly without pausing. Do not
keep the vehicle in place by depressing the
accelerator pedal; instead, apply the park-
ing brake. Otherwise, the SMG gearbox
could overheat.<
RReverse
Select reverse only when the vehicle is sta-
tionary.
NNeutral
Always engage before starting the engine,
refer to Starting the engine.
Sequential mode
Each time the engine is started, the
sequential mode is activated as soon as you move the selector lever into the for-
ward driving position.
The gears are shifted via the shift paddles
or the selector lever.
It is also possible to drive off in second
gear, e.g. on snow-covered roads.
D Drive mode
In the drive mode all forward gears are
shifted automatically.
To switch from sequential to drive mode:
tap the selector lever to the right toward D.
For rapid acceleration, e.g. during passing,
depress the accelerator pedal completely:
kickdown.
Kickdown:
In the kickdown mode, you achieve maxi-
mum acceleration.
Depress the accelerator pedal past the
increased resistance point at the full-throt-
tle position.
To switch back to sequential mode: tap the
selector lever again to the right toward D,
or change the current gear via the shift
paddles or the selector lever.
Shifting gears
With selector lever
>To upshift, tap the selector lever
toward +
>To downshift, tap the lever toward —.
With shift paddles on steering wheel
>To upshift, pull one of the shift paddles
>To downshift, push the paddle.

Driving
42 You accelerate from higher gears, e.g. dur-
ing passing, by downshifting manually.
In the following situations, the SMG in the
sequential mode assists you:
>The transmission will only execute
upshifts and downshifts that will result
in an appropriate combination of vehi-
cle speed and engine rpm. For
instance, downshifts that would result
in excessive engine speed cannot be
executed
>During a stop the gearbox is automati-
cally downshifted into first gear
>Shortly before a gear-dependent mini-
mum speed is reached, the gearbox
shifts down automatically without you
taking any action.

Malfunctions
Indicator lamp
If the indicator lamp comes on,
there is a malfunction in the trans-
mission system.
All of the selector lever positions can con-
tinue to be engaged; however, in the for-
ward drive positions the range of available
gears is restricted.
If this happens, avoid extreme engine loads
and consult the nearest BMW center.
Warning tone
An acoustic signal sounds if the SMG gear-
box overheats; if possible you should either
stop or increase your pullaway speed so
that the system can cool down.
For jump-starting and towing, refer to the
information on page 94.
Driving Dynamic Control
The Driving Dynamic Control feature lets
you select between a standard and a sport
program.
Sport program
>The engine responds more spontane-
ously to any motion of the accelerator
pedal
>The vehicle is steered more directly and
traction is enhanced
Additionally with SMG and automatic
transmission:
>The shifting times are reduced
>The engine speed range is optimally uti-
lized in the drive mode.
Activating the Sport program
In ignition key position 2
Press the SPORT button.
The LED in the button lights up.
With automatic transmission:
The sport program of the automatic
transmission is enabled by activating the
Driving Dynamic Control system. Thus, the
selector lever does not have to be shifted
from D to M/S; refer also to page 39.<

Break-in procedures
To ensure that your vehicle provides maxi-
mum economy throughout a long service
life, we request that you observe the fol-
lowing:
Engine and differential
Up to 1,200 miles / 2,000 km:
Drive at varying engine and road speeds,
but do not exceed the following engine or
road speed:
4,500 rpm / 4,500/min or
100 mph / 160 km/h.
Obey your local and state maximum speed
limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the kick-
down point.
After you have driven 1,200 miles /
2,000 km, you can gradually increase the
engine or road speeds.
You should also comply with these break-in
procedures if the engine or differential is
replaced later in the course of the vehicle's
service life.
Sequential manual gearbox SMG
Up to 1,200 miles / 2,000 km:
Avoid using the acceleration assistant dur-
ing the vehicle's break-in period.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until an initial break-in
period has elapsed. You should therefore
drive with extra caution during the first
200 miles / 300 km.
Obey your local and state maximum speed
limits.
When the vehicle is operated on wet
or slushy roads, a wedge of water
may form between the tire and the road surface. This phenomenon is referred to as
hydroplaning and can lead to partial or
complete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Brake system
Approx. 300 miles / 500 km must elapse
before the brake pads and rotors achieve
their optimal surface and wear pattern.
To break in the separate parking brake
drums, apply the parking brake lightly when
coasting to a standstill – at a traffic signal,
for instance; use caution to avoid posing a
danger to other road users.
To avoid corrosion, repeat this procedure
from time to time.
The brake lamps do not come on when the
parking brake is set.
Vacuum for the brake system servo
unit on your BMW is available only
when the engine is running. When you
move the car with the engine off, e.g. by
towing, substantially higher levels of pedal
force will be required to brake the vehicle.<
Clutch
The clutch will achieve its optimal function-
ality after approx. 300 miles / 500 km. Shift
gears carefully during the break-in period.

Giving and receiving assistance

Towing the vehicle
Always observe all applicable towing
laws and regulations.<
Towing with a commercial tow truck
>Use a wheel lift or flatbed carrier
>Do not tow with sling-type equipment.
Never allow passengers to ride in a
towed vehicle for any reason.<
Towing the vehicle with the front axle
raised
Vehicles with automatic
transmission
>Towing speed:
Maximum 45 mph / 70 km/h
>Towing distance:
Maximum 90 miles/150 km.
Vehicles with sequential manual
gearbox SMG
With the ignition on, move the selector
lever to position N, then turn off the igni-
tion.
Towing eyelet
The screw-in towing eyelet is stored in the
onboard tool kit, refer to page 88; be sure
that it remains in the vehicle at all times. It
can be attached at the front or rear of the
vehicle.
Access to towing socket
Front
Press out the cover panel with a screw-
driver inserted in the recess at the top.
Rear
Press out the cover panel with a screw-
driver inserted in the recess at the top.
Use only the towing eyelet supplied
with the vehicle and screw it in firmly
until it stops. Use the towing eyelet for tow-
ing on paved roads only. If you do not fol-
low these instructions, the towing eyelet
could be torn out and vehicle damage
could occur.
Do not tow the vehicle by any components
of the chassis or suspension, or lash them
down in any way. If you do, the compo-
nents could be damaged, possibly leading
to accidents.<
