Starting the engine
Do not run the engine in closed
rooms, as otherwise the inhaling of
toxic exhaust gases can cause uncon-
sciousness and death. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas. Never leave
an unattended vehicle with the engine run-ning, as such a vehicle represents a poten-
tial safety hazard.<
Do not allow the engine to warm up by
leaving it running while the vehicle remains
stationary. Instead, begin to drive immedi-
ately at a moderate engine speed.
When starting the engine, do not press the
accelerator pedal.
Your BMW is equipped with the con-
venience starting feature. Here, it is
sufficient to turn the ignition key only briefly
to position 3 'Start engine' and to let go of it
right away. The system responds by auto-
matically engaging the starter for a certain
period and allowing it to run until the engine
starts, after which it then disengages auto-
matically. The automatic starting mode will
not operate or will be canceled if the bat-
tery voltage is low. The engine can be
started by jump-starting, refer to
page 192.<
Press the accelerator pedal halfway down
when starting if
>the engine fails to start on the first
attempt, for instance, if it is very hot or
cold
>the engine is started at very low tem-
peratures, as of approx. +5 7/Ð156,
at high altitudes over approx. 3,300 ft/
1,000 m.
Avoid frequent starting in quick suc-
cession or repeated start attempts in
which the engine does not start. Otherwise,
the fuel is not burned or inadequately
burned and there is a danger of overheat-
ing and damaging the catalytic converter. 1.Apply the handbrake

that the vehicle is not secured against roll-
ing away.
The warning stops sounding after approx.
9 seconds.
When parking on downward inclines,
apply the handbrake. Engaging a gear
is not sufficient to secure the vehicle from
rolling away under certain circumstances.<
Handbrake
The handbrake is primarily intended to pre-
vent the vehicle from rolling while parked; it
brakes the rear wheels.

Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to engage the
handbrake while the vehicle is in motion,
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 applied.
Vehicles with manual or SMG transmission:
When parking on inclines, apply the hand-
brake, as under certain circumstances
even engaging the first or reverse gear
might not secure the vehicle against mov-
ing.
Vehicles with automatic transmission:
Place selector lever in position P.<
To prevent corrosion and one-sided
braking action, occasionally apply 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, make sure that you press the
gearshift lever to the right to prevent inad-
vertently selecting a gear in the 3rd/4th
gear level. On inclines, do not hold the
vehicle with the clutch; use the handbrake.
Holding with the clutch causes high clutch
wear.<
Reverse gear
Select R only when the vehicle is com-
pletely stopped. When pressing the gear-
shift lever to the left, overcome some resis-
tance.
The backup lamps automatically come on
in ignition key position 2.
Sequential manual
transmission SMG*
The concept
The Sequential manual transmission SMG
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 provides you with the following functions:
>Sequential mode: manual mode
>Drive mode: automatic mode
>Choice between two drive programs:
Normal, Sport, refer to page 54
>Operating reliability with protection
against incorrect gearshifts

Using shift paddles on steering
wheel
>To shift up, pull one of the shift paddles
>To shift down, press.
You accelerate from higher gears, e.g.
when overtaking, by shifting down manu-
ally.
In the following situations, the SMG in the
sequential mode assists you:
>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
>When the vehicle is stopped, the trans-
mission automatically downshifts into
first gear
>Shortly before dropping below a gear-
dependent minimum speed, the trans-
mission downshifts automatically even
without your intervention.

Indicator lamp
If the indicator lamp lights up, a
malfunction has occurred in the
transmission system.
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.
If this happens, avoid extreme engine loads
and consult the nearest BMW center.
Warning tone
In case of overheating in the area of the
transmission, an acoustic signal indicates
that you should stop or start off quickly if
possible so that the system can cool down
again.

Changing the selector-lever
positions
An interlock prevents inadvertent gear-
shifts 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.
Press the brake pedal before shifting
out of P or N; the shift command will
not be executed unless the brake is
applied: Shiftlock.
To prevent the vehicle from creeping after
you select a driving position, maintain pres-
sure on the brake pedal until you are ready
to start.<
To prevent the vehicle from rolling,
always select 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 repre-
sents a potential safety hazard.<
P Parking
Select P only when the vehicle is com-
pletely stopped. The rear wheels are
blocked.
R Reverse
Select R only when the vehicle is com-
pletely stopped.
N Neutral
Select N only if your journey is interrupted
for a long period.
D Drive Ð automatic driving 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
A kickdown provides you with maximum
acceleration and the maximum road speed
in position D.
Press the accelerator pedal beyond the
full-throttle resistance point.
M/S manual operation and Sport
program
Shifting from D into M/S activates the Sport
program and this is indicated with D S in the
gear display. This position is recom-
mended if a performance-oriented driving
style is desired.
The first time the selector lever is even
slightly touched, the automatic transmis-
sion shifts from the Sport program into
manual operation.
If you start to move the selector lever
towards +, the transmission shifts
upwards; moving it towards Ð it shifts
downwards. The gear display 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 obtain maximum acceleration, for
passing maneuvers, etc., during
operation in the manual mode, use the
kickdown or downshift manually.<

The display then appears on the Control
Display as soon as PDC is automatically
activated.
The previous display automatically reap-
pears after the system is deactivated.
Limits of the system
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors are involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with thin and
wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside your
vehicle may prevent you from hearing the
PDC signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.<
Driving stability control/
ABS Antilock Brake System
Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on ABS and DSC.
The concept
ABS enhances active safety by preventing
the wheels from locking under braking.
The ABS is operational every time you start
the engine. ABS includes the functions
CBC Cornering Brake Control and EBV
Electronic Brake Force Distribution.
In case of malfunction
If the indicator lamp lights up in yel-
low, this indicates that ABS has
been deactivated in response to a
system malfunction. Conventional braking
efficiency remains available without limita-
tions. Please have the system inspected at
your BMW center.

Technology for comfort, convenience and safety
78
CBC Cornering Brake Control
CBC is a supplement to ABS. It provides
further enhancements in vehicle stability
and steering response during lane changes
and cornering at high rates of lateral accel-
eration.
EBV Electronic Brake Force
Distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.
In case of malfunction
If the brake system warning lamp
lights up in red, appearing together
with the yellow indicator lamps for
ABS and DSC:
The driving stability control has
failed.
If all three lamps light up yellow:
Fault in the driving stability control.
The EBV electronic brake-force distribution
is active.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Please have the system checked at the
nearest BMW center.
If a message appears on the Control Dis-
play, please note the supplementary infor-
mation.
You can find more information on the
Check Control starting on page 68.
Indicator and warning lamps for
Canadian models.
Driving stability control/
DSC Dynamic Stability
Control
The concept
DSC maintains vehicle stability, even in
critical driving situations.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control, refer to
page 79.
The system optimizes vehicle stability dur-
ing acceleration and when starting from a
full stop, as well as optimizing traction. The
system recognizes any tendency for the
vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
Indicator lamps
The indicator lamp in the instrument
cluster goes out soon after you start
the engine.
If the indicator lamp flashes:
DSC is regulating the drive and braking
forces.
If the indicator lamp lights up permanently:
DSC has been switched off using the but-
ton.
If the indicator lamp and the brake
warning lamp light up permanently:
Malfunction in DSC, DTC and DBC.
When the system is off, the stability main-
tenance functions described above are no
longer available. The vehicle will remain
completely operational, however, without
DSC.
Please respond to any malfunctions by
referring the problem to your BMW center.

80 tance during panic stops. This system
exploits all of the benefits provided by ABS.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released,
DBC is deactivated.
In the event of a malfunction, the
warning lamp in the instrument
cluster lights up yellow.
Have the system checked and repaired at
your BMW center as soon as possible.
Please note any information that appears
on the Control Display.
Warning lamp for Canadian models.
Active roll stabilization*
The concept
Active roll stabilization minimizes body roll
and optimizes vehicle stability during cor-
nering and evasive maneuvers.
Dynamic stabilizers at the front and rear
axles form the basis for active roll stabiliza-
tion. Suspension compliance adapts to suit
driving conditions, varying from perfor-
mance-oriented during cornering to
smooth and comfort-oriented when the
vehicle is proceeding in a straight line.
The system assumes operational status
each time you start the engine.
Driving with active roll stabilization
During vehicle operation, the system con-
tinuously runs through closed-loop control
cycles lasting only fractions of a second.
In case of malfunction
The symbol in the instrument clus-
ter lights up and a message
appears on the Control Display.
Please note any supplementary information
that appears there.
You can find more information on the
Check Control starting on page 68. If the active roll stabilization system is
deactivated in response to malfunc-
tion, please remember to adapt your speed
accordingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater ten-
dency to tilt during cornering and in cross-
winds.
If a message stating that you should stop
appears on the Control Display in addition
to the red symbol, stop immediately and
switch off the engine. In this case the oil
level in the reservoir may have dropped
below the minimum, possibly owing to a
leak in the hydraulic system.
Please note any supplementary information
that appears on the Control Display.<
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires as
you drive. The system provides an alert
whenever the inflation pressure drops sig-
nificantly in relation to the pressure in
another tire.
The check of the tire inflation pressure is
based on monitoring the relative speeds of
the wheels. A flat tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirement
So that the Flat Tire Monitor can learn the
correct inflation pressure, please perform
the following:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure
table on page 170 and correct if neces-
sary
3.Initialize the system.
Limits of the system
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused
by outside factors and does not detect a

natural, even pressure drop in all four
tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When you are driving on snow-covered
or slippery road surfaces
>If you are using a sports driving style:
slip on the drive wheels, high lateral
acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted
>When you are driving with the compact
wheel, the Flat Tire Monitor is unable to
function.
Initializing the system
Perform the initialization immediately
after correcting the inflation pressure,
after changing a tire or changing a wheel or
all wheels. A drive is necessary for this pur-
pose.<
Control Center, for principle details, refer to
page 16:
1.Before beginning driving, start the
engine, but do not drive off
2.Open the menu
3.Select "Vehicle settings" and press the
controller
4.Select "FTM" and press the controller
5.Select "Set tire pressure" and press the
controller
6.Select "Yes" and press the controller
7.Drive off.
The message "Initializing" is displayed.It takes a few minutes before the Flat Tire
Monitor can detect and report a flat tire.
After the initialization is completed, the
message "Active" is displayed.
If a flat tire is detected during initialization,
a message appears on the Control Display.
When driving with snow chains or
with the compact wheel, do not initial-
ize the system.<
Flat tire
Indicator lamp
The symbol in the instrument clus-
ter lights up in red and a simulta-
neous message appears on the
Control Display. In addition, an acoustic
signal sounds.
Please note any supplementary information
that appears on the Control Display. You
can find more information on the Check
Control starting on page 68.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2.Identify damaged tire
If identification is not possible,
contact your BMW center.<
3.Replace the damaged wheel, refer to
Changing a tire on page 187.
Vehicles with run-flat tires:
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
edges of the run-flat tires, inflation
pressure loss can not usually be recog-
nized from the outside, refer to Run-flat
tires on page 175.<
2.To continue driving, comply with the
instructions for driving with damaged
tires on page 175.
