Before installing any child-
restraint device or child seat,
please read the following:
Never install a rearward-facing child-
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rearward-facing child-restraint
system – of the kind designed for
infants under 1 year and 20 lbs/9 kg –
would be within the airbag's deploy-
ment range, you should never mount
such a device in the front passenger
seat, since the impact of the airbag
against the child-restraint's backrest
could lead to serious or fatal injuries.
If it is necessary for a child – not an
infant – to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the dashboard as possible. This
important precaution is intended to
maximize the distance between the air-
bag and the child. Older children
should be tightly secured with a safety
belt after they have outgrown a booster
seat that is appropriate for their age,
height, and weight. Younger children
should be secured in an appropriate
forward-facing child-restraint system
that has first been properly installed
with a safety belt.
Never install a rearward-facing child-
restraint system in the front passenger
seat.
We strongly urge you to carefully read
and comply with the instructions for
installation and use provided by the
child-restraint's manufacturer whenever
you use such a device.
Do not attempt to modify child-restraint
systems. If you do this, the protection
provided by these systems could be
impaired.
Always ensure that all occupants – of all
ages – remain properly and securely
restrained at all times.<
All rear seating positions in your vehicle
meet the recommendations of
SAE J1819, an industry-recommended
practice for securing child-restraint sys-
tems in motor vehicles.
Securing child-restraint systemAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child-
restraint systems.
A label with the appropriate instructions
for this is located in the immediate
vicinity of the buckle latch of each
safety belt.To lock the safety beltExtract the entire length of the belt from
the inertia reel mechanism. Allow the
reel to retract the belt somewhat and
engage the buckle, then tighten the belt
against the child-restraint system. The
retraction mechanism is now locked.

Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own individ-
ual preferences. In engineering your
vehicle, BMW has provided for a num-
ber of options for personal adjustment
that can be programmed into your vehi-
cle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle –
Vehicle Memory – or the individual –
Key Memory. Provided that each per-
son has a separate remote-control key,
you can have your BMW center enter
basic adjustment data for up to four
individuals in the system.
The system then relies on a bilateral
data exchange to identify the individual
user and executes the selected settings
whenever the remote control unit is
used to disengage the door locks.
Distinguishing between keysColor-coded decals have been pro-
vided to help you distinguish individual
keys with different settings.What the system can doYou can learn about the entire array of
features this system offers at your BMW
center.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<

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.<

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

Automatic transmission with Steptronic*You can drive as with a normal auto-
matic transmission. In addition, you can
also shift manually.
When you move the selector lever from
the D position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. Steptronic enters the
manual selection mode and executes
the desired shift whenever you tap the
selector lever in the direction indicated
by + or –. Whenever you want to use
automatic again, just move the selector
lever toward the right to position D.
Under normal operating conditions, fuel
consumption is lowest when driving in
position D.Selector lever positions P R N D M/S + –Starting the engineThe engine can only be started in selec-
tor lever positions P – for Park – or N –
for Neutral.
Range selectionA catch prevents inadvertent movement
of the selector lever to positions R and
P. To deactivate the catch, press the
button on the front of the selector lever
knob, see arrow.
While the vehicle is stationary and
before shifting out of Park or Neu-
tral, depress the footbrake in order to
disengage the selector lever's lock
mechanism – Shiftlock.<
Hold the footbrake down until
starting off. The vehicle will other-
wise 'creep' when a drive position is
engaged. To prevent the vehicle from
starting off on its own, always move the
selector lever to position P and engage
the parking brake before leaving your
vehicle with the engine running.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a safety hazard.<

KickdownIn the kickdown mode, you achieve
maximum acceleration and top speed
in position D.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
M/S manual operation and Sport
programMove the selector lever from D to M/S
to activate the Sport program; SD
appears in the display panel. The M/S
mode is recommended for perfor-
mance-oriented driving.
Once in the M/S mode, you can tap the
selector lever to switch the automatic
transmission from the Sport program to
its manual mode.
This mode allows you to execute
upshifts manually by tapping the lever
toward +, while downshifts are selected
by tapping in the – direction. The dis-
plays M1 through M5 appear in the dis-
play panel to indicate your current gear
selection.
The transmission will only execute
upshifts and downshifts that will result
in an appropriate combination of vehi-
cle speed and engine rpm. For
instance, downshifts that would result
in excessive engine speed are not exe-
cuted. The desired, then the actual
gear, briefly appear in the instrument
cluster.
To accelerate quickly in the man-
ual mode for maneuvers such as
passing another vehicle, shift down
manually or employ the kickdown
mode.<
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.
