Luggage compartment lidTo open from the insideIf the luggage compartment lid has not
been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is
stationary.
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, as with all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
completely closed. Otherwise, exhaust
fumes could penetrate the interior of
the vehicle. Should it be absolutely
necessary to operate the vehicle with
the luggage compartment lid open:
>Close all windows and the sliding/tilt
sunroof
>Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
pages 83, 86.<

Starting the engine Switching off the engine If the engine does not start on the first
attempt (the engine is very hot or cold,
for instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures,
starting at about +57 (Ð156) and at
high altitudes over 3,300 ft (over
1,000 m):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to damage to the
catalytic converter.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in personal injury
and property damage.<
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from
discharging, always switch off electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.Turn the ignition key to position 1 or 0.
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.
Set the parking brake when parking on
steep hills, because under certain
conditions, putting the vehicle into first
or reverse gear may not be enough to
prevent it from rolling away.<
Vehicles with sequential M transmis-
sion
* SMG II: observe instructions on
page 60.

Sequential M gearbox* SMG IIDrivelogicDrivelogic makes various driving
programs available to you.
Press Drivelogic repeatedly until the
desired driving program is shown in the
SMG display of the instrument cluster,
refer to page 61.
In the automated mode you can select
from five driving programs ranging from
convenience mode/winter operation to
sporty and highly dynamic.
In the first automated driving program,
starting off takes place in second gear,
which is advisable under winter road
conditions with ice and snow.
In the sequential mode you can choose
from six driving programs ranging from
balanced, dynamic to sporty, puristic
driving. The sporty, puristic driving
program can only be activated with the
Dynamic Stability Control (DSC) deacti-
vated, refer to page 76.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
Following each change between the
sequential and the automated mode,
the last driving program selected in the
respective mode is active.
Exception: instead of the last selected
sequential driving program 6,
program 5 is activated only after the
engine has been started again.
Your vehicle is set so that when
the engine is started, the last
selected driving program saved in your
key is activated for each shifting
mode.<
Gradient assistanceThe gradient assistance enables
starting off on grades with virtually no
roll-back. It can be activated in the
sequential and automated mode with
the vehicle stopped and can be used
for both forward and reverse driving.
1. Depress footbrake with vehicle
stopped
2. Activate the gradient assistance by
pulling the left paddle for at least
0.5 seconds. An increase in the
engine speed indicates that the
gradient assistance is activated.
Pulling the left paddle again briefly
deactivates the gradient assis-
tance again.<
3. Release the footbrake and start off
within 2 seconds.

Sequential M gearbox* SMG II
Indicator/Headlamp ßasher
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.
2 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. 1 High beams (blue indicator lamp)
2 Headlamp flasher (blue indicator
lamp)
3 Turn signal indicator (green indicator
lamp accompanied by periodic
clicking sound from the relay)
To signal brieflyPress the lever up to but not beyond
the resistance point. It then returns to
the center position when released.
If the indicator lamp of the turn
signal indicators and the clicking
from the relay are both faster than
normal, one of the turn signal indicators
has failed.<

Dynamic Stability Control (DSC)

The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it also recognizes
unstable driving conditions such as
under- or oversteering on curves, and
helps the vehicle remain on a steady
course by using the engine and brake
system to intervene at the different
wheels Ð doing only what it can within
the laws of physics, of course.
The DSC is operational every time you
start the engine. The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
At first, you may need some time to
become accustomed to this system's
intervention. However, it guarantees
optimum drive force and at the same
time, the best possible vehicle stability.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
>Indicator lamp flashes: the DSC is
active and is controlling the drive
torque based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: the DSC has been
deactivated via the button or there is
a malfunction. You can continue to
drive the vehicle normally, but
without DSC. Please consult your
BMW center for repairs.

Air conditionerAir supply (blower)
You can select blower speeds
from 1 to 4. The heating and
ventilation become more and
more effective as the air
supply settings are increased. In posi-
tion 0, the blower and the heater are
switched off. By using position 0, you
can totally block the air supply by
pressing the button for the recirculated-
air mode.
Temperature
In order to increase the
temperature of the passenger
compartment, turn it to the
right (red). Temperature regu-
lation will keep the interior temperature
you have selected constant.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . All intermediate
settings are possible. In the setting,
there is a low flow of air onto the
windows to keep them free of conden-
sation.
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
The rear window defroster auto-
matically assumes operation
within 5 minutes after the engine is
started at outside temperatures below
40 7 (4 6).<
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð warmed again
when the air conditioner system is
switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
You can respond to unpleasant
external odors by temporarily
excluding the supply of outside air. The
system then recirculates the air
currently within the vehicle.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<

Air conditionerDraft-free ventilation You can adjust the blower controls for
the upper body area to select the
optimum airflow rates and directions for
your personal requirements:
1 Rotary dials for opening and closing
the vent outlets through an infinitely
variable range
2 Lever for adjusting airflow direction
3 With the rotary dial you can adjust the
temperature of the outgoing air:
>Turn toward blue Ð colder
>Turn toward red Ð warmer.
MicrofilterA microfilter, which traps incoming dust
and pollen, has been installed in your
vehicle. Your BMW center will replace it
during routine maintenance. A substan-
tial reduction in airflow indicates that
the filter needs to be replaced early.
To defrost windows and remove
condensation1. Set the blower speed control for the
air supply rate to position 4
2. Turn the rotary temperature control
completely to the right (red)
3. Rotary control for air distribution in
position
4. Switch on the rear window defroster
to defrost the rear window.
