Vehicles with automatic transmis-
sion:
Do not move the selector lever from
position P until the engine is running,
ignition key position 2.
Your vehicle is equipped with an inter-
lock. Therefore, the ignition key cannot
be turned to position 0 or removed until
the selector lever is in position P.<
Vehicles with manual transmis-
sion:
Step on the clutch when starting the
vehicle. A lockout prevents the engine
from starting if the clutch is not
depressed.<
Steering lockedThe key can only be inserted and
removed in this position.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
the lock engages.
If the key is not removed, an acoustic
signal is sounded after the driver's door
has been opened.Steering unlockedYou will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.
Individual electrical accessories are
ready for operation.
Starting the engine
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.
When driving, standing at idle or park-
ing the vehicle, take care to avoid con-
tact between the hot exhaust system
and flammable materials – grass, hay,
leaves, etc. Such contact could lead to
a fire, resulting in serious personal
injury and property damage.<
Start the engine. Do not press the
accelerator pedal.
Do not actuate the starter for too
short a time, but do not actuate it
for more than approx. 20 seconds.
Release the ignition key immediately
when the engine starts.<

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.Automatic transmissionMove the selector lever into position P,
and turn the ignition key to position 1 or
0.SMG gearboxIf you turn the ignition key to position 1
or 0 with the selector lever in position
R, or in sequential mode, a gear auto-
matically 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 indicator in the display
remind you that no gear is engaged to
secure the vehicle against rolling.
The warning stops after approx.
9 seconds.
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 and lower the lever.

Sequential manual gearbox SMG*The conceptThe 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 the selector
lever in the center console and two shift
paddles on the steering wheel.
It offers the following functions:
>Sequential mode: manual mode
>Drive mode: automatic operation
>Ability to choose between two differ-
ent driving programs: Standard,
Sport
>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, refer to
page 70.
Selector lever positionsThe current selector lever position is
indicated by a light-emitting diode in
the center console.
R: Reverse
N: Neutral
Position for forward driving with one-
touch functions:
Sequential mode
+: manual upshifts
—: manual downshifts
D: drive mode.
The SMG is ready for operation in igni-
tion key position 2.
The gearbox is automatically
placed in neutral gear if the
driver's door is opened while the engine
is running and the driver does not actu-
ate the pedals, the shift paddles or the
selector lever.
This is accompanied by an acoustic
signal and the flashing gear indicator.
The gear display N appears in the
instrument cluster.
A driving position can only be engaged
when the driver's door is closed.
When the vehicle is unlocked, a buzzer
in the area of the transmission indicates
that the system is ready for operation.<
ShiftlockWhen the car is at a standstill, a safety
function requires you to depress the
brake pedal if you want to move the
selector lever from the neutral
position N to a driving position.Driving precautions
Use enough acceleration to pull
away speedily when moving off on
an uphill gradient. Never try to prevent
the car from rolling back on an uphill
gradient by depressing the accelerator
pedal; always apply the handbrake.
Otherwise you could overheat the SMG
gearbox.<

RReverseSelect only when the vehicle is station-
ary.NNeutralAlways engage before starting the
engine, refer to Starting the engine on
page 64.Sequential modeEach time the engine is started, the
sequential mode is activated as soon as
you move the selector lever into the for-
ward driving position while the brake is
depressed.
The gears are shifted via the shift pad-
dles or the selector lever.
It is also possible to drive off in second
gear, e.g. on snow-covered roads.DDrive modeIn 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.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.
KickdownYou can achieve maximum acceleration
using kickdown.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
Shifting gearsWith 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 pad-
dles
>To downshift, push the paddle.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
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 vehicle speed and engine rpm. For

Cruise control*Starting at about 20 mph / 30 km/h, you
can maintain and store any vehicle
speed that you specify.
The cruise control is operational when-
ever the engine is running and the sys-
tem has been activated.To activate the systemIn ignition key position 2: press the but-
ton in the steering wheel. The indicator
lamp in the instrument cluster comes
on, refer to page 20. You can now use
the cruise control.
Do not use cruise control on twist-
ing roads, when high traffic den-
sity prevents driving at a constant
speed, or when the road surface is slick
– snow, rain, ice – or loose – rocks or
gravel, sand. until the indicator lamp in the instru-
ment cluster goes out.
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
approx. 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. 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 controlWhen the system is activated, 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:
>When the brakes are applied
>When you apply pressure to the
clutch pedal, or when you move the
automatic transmission selector lever
from D to N
>If you exceed or fall below the preset
speed for an extended period – by
depressing the accelerator, for exam-
ple.

Computer*Mode selectionWith the ignition key in position 1 or
higher, you can call up information from
the computer using the button in the
turn signal lever. By pressing the button
briefly toward the steering column, you
can call up a new function for display.
The displays appear in the following
order:
Time of day, outside temperature, aver-
age fuel consumption, cruising range,
average vehicle speed.
With the ignition key in position 1 or
higher, the last active setting is dis-
played.
Outside temperatureYou can change the units of measure
6/7 for the outside temperature dis-
play by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active. The
units of measure 6/7 in the tempera-
ture display of the automatic climate
control change automatically, refer to
page 100.Ice warningIf the outside temperature drops to
about 37.57/+36, then the computer
will automatically switch to a display of
the outside temperature. In addition, a
signal sounds as a warning and the dis-
play flashes for a brief period.
After giving an ice warning, the
display returns to the previous
setting.<
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.57/+36, on
bridges or shaded road surfaces, for
instance.<

Hill Descent Control (HDC)*The conceptBy reducing the vehicle's speed on
steep downhill stretches, HDC main-
tains predictable vehicle handling
response to provide you with control of
your BMW during extreme descents.
The vehicle slows to a pace just slightly
faster than walking speed.
HDC is available for activation at vehi-
cle speeds below approx. 22 mph /
35 km/h. When driving down steep
hills, the vehicle reduces speed auto-
matically down to about double walking
speed – approx. 7.5 mph / 12 km/h –
and then maintains this speed at a con-
stant.
You can use the accelerator or brakes
to vary this speed within a range from
approx. 3 mph / 5 km/h to approx.
15 mph / 25 km/h.
In conjunction with the multifunction
steering wheel you can use the +/–
button to set the cruise control to a tar-
get speed in the range from approx.
3 mph / 5 km/h to approx. 15 mph /
25 km/h.
HDC is automatically deactivated once
vehicle speed again exceeds approx.
37 mph / 60 km/h.
To activate the systemPress the HDC button; the green indi-
cator lamp integrated within the button
comes on.
The indicator lamp flashes whenever
the system is actively intervening to
control your speed with automatic
brake applications.To deactivate the systemPress the button again, the indicator
lamp goes out.
HDC is automatically deactivated once
the vehicle accelerates to more than
37 mph / 60 km/h, as well as whenever
you switch off the ignition.
To use HDCWith manual transmission:
You should always ensure that either
reverse or first gear is engaged before
using HDC, as the engine's braking
effect is most pronounced in these
gears, and only reduced engine braking
is available in higher gears.
With automatic transmission: HDC is
available for use in all ranges.System malfunctionsSignaled by the indicator lamp, which
responds to problems by going out
while HDC is in operation or by failing
to come on when you activate the sys-
tem:
HDC is temporarily not available if
brake temperature is too high.
If the DSC indicator lamp comes
on at the same time:
There is a fault in the HDC and
DSC systems. Have your BMW center
inspect this system as soon as possi-
ble.

When driving with snow chains or
a space-saver spare tire, do not
initialize the system.<
Flat tire
The indicator lamp in the instru-
ment cluster lights up red. This
visual alert is accompanied by
an acoustic warning signal.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 147.
After replacing the damaged tire, initial-
ize the system.
Vehicles with Run Flat tires:
1. Carefully reduce your speed to under
50 mph / 80 km/h. Avoid strong
braking and steering maneuvers. Do
not exceed a speed of 50 mph /
80 km/h.
Because the sides of Run Flat
tires are reinforced, a drop in infla-
tion pressure usually cannot be
detected from the outside, refer to Run
Flat tires, page 150.<
2. To continue driving, follow the
instructions under Driving with a
damaged tire on page 151.
System malfunction
The indicator lamp in the instru-
ment cluster lights up yellow.
The Flat Tire Monitor is malfunc-
tioning or out of order. Please refer the
problem to your BMW center.
Brake force displayThe brake force display indicates to the
driver of the vehicle behind you how
hard you are braking your vehicle.
The display has two levels:
>Normal braking: the brake lamps
among the rear lamps and the center
brake lamp light up
>Hard braking or use of ABS: the tail
lamps light up with the same bright-
ness as the brake lamps and thereby
intensify the visual effect of the brake
lamps.
