Starting engine
Do not run the engine in closed rooms, as
otherwise the inhaling of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the engine running, as such a vehicle represents a
potential safety hazard.
To prevent the vehicle from rolling, always
select neutral position or position N and apply
the handbrake before leaving the vehicle with
the engine running.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive immediately at a moder-
ate engine speed.
Special starting conditions
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 tempera-
tures, below approx. 57/–156, at high
altitudes, over approx. 3,300 ft/1,000 m.
Avoid frequent starting in quick succes-
sion 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 overheating and damaging the cat-
alytic converter.<
Manual transmission
1.Apply the handbrake.
2.Gearshift lever in neutral position.
3.Press the clutch pedal.
If the clutch pedal is not depressed,

4.Start the engine.
Do not end the starting procedure too early,
however after approx. 20 seconds at the lat-
est. Release the ignition key immediately as
soon as the engine starts.

SMG Sequential manual transmission
and automatic transmission
Your BMW is equipped with the convenience
starting feature. It is sufficient to turn the igni-
tion key into position 3 for only a short time and
then release it again. The system responds by
automatically engaging the starter for a certain
period and allowing it to run until the engine
starts, after which it then disengages automati-
cally.
SMG Sequential manual transmission
1.Press the brake pedal.
2.Place selector lever in position N.
3.Start the engine.
If the engine does not start, shift back to
the last gear selected, refer to Instrument
cluster display, and then shift into position N.<
Automatic transmission
1.Press the brake pedal.
2.Place selector lever in position P or N.
3.Start the engine.
Switching off engine
Do not remove the ignition key while the
vehicle is rolling, as otherwise the steer-
ing wheel lock will immobilize the steering.
When leaving the vehicle, remove the ignition
key and lock the steering. When parking on a
downhill incline, apply the handbrake, as other-
wise the vehicle could roll away.<

Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If it becomes necessary under special cir-
cumstances to use the handbrake while
driving, it must not be pulled too sharply. In
doing so, continuously 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 hand-
brake is applied.<

SMG Sequential manual
transmission*
The concept
The SMG Sequential manual transmission is an
automated manual transmission in which an
electrohydraulic 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 you the following functions:
>Optional manual or automatic operation:
Sequential mode or Drive mode
>You have a choice of two driving programs:
Normal or Sport, refer to Dynamic Driving
Control page54 >Automatic downshifting and prevention of
incorrect shifting even in sequential opera-
tion
>Acceleration assistant, refer to page55.
The SMG is operational when the ignition key is
in position 2.
Selector lever positions
The current selector lever position is displayed
on the center console.
>R: Reverse
>N: Neutral
>One-touch functions for Sequential mode:
+: manual upshifting
–: manual downshifting
>D: Drive mode
The transmission automatically shifts into
N if the driver's door is opened with the
engine running and neither the pedals, the shift
paddles nor the selector lever are operated.
This is indicated by an acoustic signal and the
flashing display N in the instrument cluster.<

Active cruise control*
The concept
With active cruise control, you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is a technological advance
over the familiar cruise control and is a welcome
relief from the constant adjustment of speed
that can accompany driving in traffic on free-
ways or other high-speed thoroughfares. Espe-
cially on longer trips, the system can reduce
fatigue and tension, while increasing your
enjoyment of driving. Please use it safely and
responsibly.
In addition to holding a steady cruising speed,
if you encounter slower vehicles ahead, active
cruise control will, within the scope of given
possibilities, adjust your vehicle's speed auto-
matically so that you can flow with the traffic
without having to make constant adjustments.
If, for example, while cruising at the selected
speed, you begin to approach a slower vehicle
ahead of you in the same lane, the system will
reduce your vehicle's speed to the same as that
of the vehicle ahead to maintain your selected
distance setting between your vehicle and the
vehicle ahead. There are four settings for dis-
tance, which are additionally speed-dependent.
Based on your selected distance setting, the
system automatically decreases the throttle
setting and lightly applies the brakes if neces-
sary. The vehicle brake lamps will automatically
illuminate to signal a following driver to take
action. In addition, it may be necessary for the
vehicle or the driver to downshift, depending on
the kind of transmission your vehicle is
equipped with, to maintain the distance setting
selected. If the vehicle ahead speeds up or
when the lane ahead becomes clear, your vehi-
cle will accelerate to the speed you have
selected by increasing the throttle setting and
shifting gears automatically or by the driver as
needed.

Driving
60 Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
Since this active cruise control system is
a new technology and operates differ-
ently from conventional cruise control systems
which you may be accustomed to, you are
strongly urged to read all of the pages relating
to this system before use. Pay special attention
to the information contained in the Things to
know about active cruise control section in this
manual beginning on page62.<
Vehicles with manual transmission
You can use the system in the 2nd to 6th gear
within a normal engine speed range and also
change gears. Continuous operation at very
high or very low engine speeds is not possible.
In this case the driver is asked to shift or the
system deactivates itself.
Vehicles with SMG
Continuous operation at very high engine
speeds is not possible in the Sequential mode.
In this case the driver is asked to shift or the
system deactivates itself.
In the Drive mode, the SMG acts similarly to the
automatic transmission in the D position.

Adjust your desired speed to the traffic
conditions and remain ready to brake at
all times. Great differences in speed to the vehi-
cles driving ahead, e. g. when quickly approach-
ing a truck or when another vehicle swerves into
your lane, cannot be compensated for by the
system.<

Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example, at a traffic light or a
parked vehicle. Also, the system does not react
to oncoming traffic, pedestrians or other types
of potential traffic such as a rider on horseback.
It is also possible that the system may not
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide
a warning to you. Also, be aware that every
decrease in the distance setting allows your
vehicle to come closer to a vehicle in front of
you and requires a heightened amount of alert-
ness.<
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts the transmission to neutral/N, or
deactivates DSC. After any deactivation, the
system will no longer automatically activate the
vehicle brakes, which means the driver must intervene and resume manual braking. You
should then reactivate the system only when
you are fully aware of the prior speed and dis-
tance settings.<
Active cruise control may brake when you
reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway.
In approaching a curve, it is possible that active
cruise control would react briefly to a vehicle in
the adjacent lane. In addition, the system can
sense if your vehicle is in a curve and may not
accelerate. If your vehicle decelerates in either
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.

Driving
64
Driver interventions
Anytime the driver presses down on the
accelerator pedal, any automatic braking
action by the system is interrupted until the
pedal is fully released. After doing this, release
the accelerator and the system again controls
your cruising speed and distance setting. While
driving with activated system, resting your foot
on the accelerator pedal will cause the system
not to brake even if necessary. Be certain that
floormats or other objects on the vehicle floor
do not interfere with movement of the accelera-
tor pedal.<
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, particu-
larly if you are driving down a steep grade or
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: during emergency braking,
when you approach a vehicle traveling at a
much lower speed than your own speed such as
approaching a toll booth or when a much slower
vehicle cuts in front of you at close range.<
Whenever active cruise control
recognizes a situation that requires
driver braking because the system
capacity has been reached or has
been exceeded, the system alerts
the driver by flashing this symbol in the instru-
ment cluster and sounding a signal.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
Malfunction
The indicator lamp lights up and a mes-
sage appears on the Control Display.
The build-up of foreign matter, e. g.,
snow, ice, dirt, road debris etc., can lead to
reduced detection performance of active cruise
control. You should check the sensor under the
front bumper and clean it as necessary prior to
driving your vehicle. If the sensor becomes cov-
ered by foreign matter or has a malfunction, it is
possible that the sensor will no longer be able to
detect vehicles in front of you. After the system
recognizes that the sensor is no longer func-
tional, a message is displayed on the Control
Display and an acoustic signal is emitted.
When the system does not recognize any
objects, e.g. on infrequently traveled roads
without a shoulder or guard rails, the system
can automatically deactivate temporarily.

Technology for comfort, convenience and safety
78
DSC Dynamic Stability Control
The system prevents traction loss in the driving
wheels when starting off and accelerating. DSC
also detects unstable driving conditions such
as a fishtailing rear end or sliding of the front
wheels. In these cases, DSC helps the vehicle
maintain a safe course within physical limits by
reducing engine output and through braking
actions in the individual wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks.<
DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC

Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not longer
than approx. 10 seconds. Stabilizing and drive
output promoting actions are no longer exe-
cuted. In addition, the stability promoting inter-
vention of the active steering is deactivated,
refer to page81.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To increase vehicle stability, activate DSC again
as soon as possible.
