Starting engine and driving off
Do not allow the engine to warm
up by leaving it running while the
vehicle remains stationary. Instead,
drive off immediately at a moderate
engine speed.<
Do not allow the engine to run in
enclosed spaces. Otherwise,
breathing the exhaust fumes can lead
to unconsciousness and death. The
exhaust gases contain carbon monox-
ide, an odorless and colorless, but
highly toxic gas. Do not leave the vehi-
cle unattended with the engine running.
An unattended vehicle with a running
engine represents a safety hazard.<
If the engine does not start on the first
attempt, such as when it is very hot or
cold:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures
below about 57/–156 and at high
altitudes above 3,300 ft/1,000 m:
>On the first start attempt, it may be
necessary to engage the starter for a
longer period, but no longer than
20 seconds.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can damage the catalytic
converter.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the hot
exhaust system and flammable materi-
als – grass, hay, leaves, etc. Such con-
tact could lead to a fire, resulting in
serious personal injury and property
damage.<

turn it for more than approx.
20 seconds. Release the ignition key
immediately when the engine starts
4. Engage a driving position
5. Release footbrake and slowly
depress accelerator pedal.
With the engine running, the gear
indicator in the SMG display
flashes to indicate that a driving posi-
tion is engaged with the driver's door
open or if the hood is not closed prop-
erly, refer to page 72.
If none of the pedals is actuated, then
the gearbox is automatically taken out
of gear after approx. 4 seconds. Then
the desired direction of travel must be
selected again with the selector lever in
position 0. Driving off is not possible
with the hood open.<
Before exiting the vehicle with the
engine running, move the selector
lever into position 0 and apply the park-
ing brake.
Never leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a safety hazard.<

Switching off the engine
You should never remove the igni-
tion key when the vehicle is in
motion, as the steering lock could
engage.
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.
Engaging a gear may not sufficiently
secure the vehicle against rolling.<
Manual transmissionTurn the ignition key to position 1 or 0.Sequential M gearbox SMG IIIf you turn the ignition key to position 1
or 0 with the selector lever in the for-
ward or reverse position, a gear auto-
matically remains engaged.
If you turn the ignition key to position 1
or 0 with the selector lever in position 0,
a warning tone and the flashing gear
indicator in the SMG display remind you
that the vehicle is not secured against
rolling.
The warning stops after approx. ten
seconds. If you move the selector lever
into a forward or reverse position dur-
ing this time, a gear is automatically
engaged.
Parking brakeThe parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates against the rear
wheels.To engageThe detent engages automatically, and
the indicator lamp in the instrument
cluster comes on when the ignition key
is in position 2, refer to page 18.To releasePull up slightly on the lever, press the
button – see arrow – and lower the
lever.

Sequential M gearbox SMG II*The conceptThe sequential M gearbox SMG II is an
automated manual gearbox with which
clutching and shifting is assumed by an
electro-hydraulic system.
The SMG II is operated via two shift
paddles on the steering wheel and the
selector lever in the center console.
It offers the following functions:
>Sequential and automated shifting
mode
>Ability to choose between different
driving programs, Drivelogic
>Gradient assistance, refer to page 74
>Upshift display and shift lights, refer
to page 75
>RPM matching on downshifts
>Driving dependent functions:
The respective driving situation, e.g.
cornering, mountain driving or brak-
ing, is detected by sensors and taken
into account for shifting, e.g. to
achieve optimum gear selection dur-
ing deceleration and subsequent
acceleration
>Slip recognition at the rear axle for
increasing driving stability, e.g. dur-
ing downshifting on slippery road
surfaces
>Operating safety through protection
against misshifting.Under normal operating conditions, fuel
consumption is lowest when driving in
the first driving program of the auto-
mated shifting mode.
Selector lever positionR: Reverse position
0: Position 0 (Neutral)
Forward position with one-touch mode:
>S: sequential mode
>A: automated mode
>+: upshifting in sequential mode
>–: downshifting in sequential mode.
The SMG II is ready for operation from
ignition key position two or higher.
For your safety, it is only possible to
engage a driving position with the vehi-
cle stopped approx. 2 seconds after
engaging position 0 with the footbrake
depressed – Shiftlock function.

Shifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right pad-
dle +
>To downshift, briefly pull the left pad-
dle –.
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW cen-
ter.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward +
>To downshift, push the selector lever
forward toward –.
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations the SMG II
helps you think in the sequential mode:
>Upshifts and downshifts are only exe-
cuted when the new gear will provide
a suitable combination of vehicle and
engine speed, i.e., downshifts 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 with-
out you taking any action.A – 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 72.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely – kickdown. 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.

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 lim-
ited 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 opti-
mum 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
after mounting or removing snow
chains, the slip recognition of the
SMG II must become familiar with the
changed condition.
Reinitialize the system afterwards:
1. Move the selector lever into
position 0 on a straight stretch of
road at a speed of over 20 mph /
30 km/h
2. Pull both shift paddles for approx.
two seconds.
If you do not carry out the initialization,
the system automatically learns the
changed condition gradually during
driving. This can become apparent due
to brief opening and closing of the
clutch.

You can set the wipe interval at four
stages with rotary dial 5. In addition, the
wipe interval is varied automatically
depending on road speed.
Rain sensorThe rain sensor is positioned on the
windshield, directly behind the interior
rearview mirror.
To activate the rain sensor:
>With the ignition key in position 1 or
higher, move the lever to position 1.
The wipers travel once across the
windshield, regardless of the weather
>You can leave the lever permanently
in position 1. It is then only necessary
to activate the rain sensor when the
ignition key is in position 1 or higher.
Activate by briefly turning rotary dial
5.
To adjust the sensitivity of the rain sen-
sor: turn rotary dial 5.
To deactivate the rain sensor: put lever
in position 0.
Turn the rain sensor off in auto-
matic car washes. Failure to do so
could result in damage caused by
undesired wiper activation. ers switch automatically to intermittent
wipe – not on vehicles with rain sensor.
Fast wiper speedWhen the vehicle is stationary, the wip-
ers operate at normal speed – not on
vehicles with rain sensor.

Cruise control is also deactivated when
the ignition key is in position 0.
The speed stored in memory is deleted.To store and maintain speed or to
acceleratePress button "+" briefly:
The system stores and maintains the
current vehicle speed. Every time you
tap the button, the speed increases by
0.6 mph / 1 km/h.
Press and hold button "+":
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
stores and maintains the current speed.
If on a downhill gradient the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
To deceleratePress button "–" briefly:
When cruise control is active, every tap
of the button reduces the speed by
approx. 0.6 mph / 1 km/h.
Press and hold button "–":
With the cruise control active, the sys-
tem automatically reduces the throttle
opening to slow the vehicle. When you
release the button, the system stores
and maintains the current speed.To interrupt the cruise controlEach time zou activate the system,
press the button. The indicator lamp
stays on. You can use the cruise control
again whenever you want by calling up
the speed that was stored last.
In addition, cruise control is interrupted
automatically:
>If the brakes are applied
>When pressing down the clutch pedal
>If you exceed or fall below the pro-
grammed speed for an extended
period – by depressing the accelera-
tor, for example
>Sequential M gearbox SMG II, refer
to page 71: when shifting in the
sequential mode.To recall the stored settingPress button:

Fuel gaugeOnce the indicator lamp stays on con-
tinuously, there are still approx.
2 gallons/8 liters of fuel in the fuel tank.
Fuel tank capacity approx. 16.6 gal./
63 liters.
If the tilt of the vehicle varies – when
you are driving in mountainous areas,
for example – the needle may fluctuate
slightly.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Engine coolant temperature gaugeBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on while operating
the vehicle: the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
To check the coolant level, refer to
page 126.
Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector during normal operation.
