Alarm system
*
The conceptThe vehicle's alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movement inside the vehicle
(interior motion sensor)
>To a change of the vehicle's tilt Ð if
someone attempts to steal the wheels
or tow the vehicle without authoriza-
tion, for example
>If there is an interruption of battery
voltage.
The alarm system signals unauthorized
access to the vehicle or an attempted
theft in different ways:
>Sounding an acoustical alarm for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or with the remote con-
trol, the alarm system is also simulta-
neously armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have fin-
ished locking the car.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once. An acoustic warning signal
sounds at the same time.
You can have different acknow-
ledgment messages set to confirm
arming and disarming.<
You can also open the luggage com-
partment lid when the system is armed
by pressing button 3 of the remote con-
trol (refer to page 37). When it is closed,
the lid is once again secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes con-
tinuously: The system is armed.
>If the indicator lamp flashes during
arming of the system: The door(s),
the hood or luggage compartment lid
are not completely closed. Even if
you do not close the alerted area, the
system begins to monitor the remain-
ing areas, and the indicator lamp
flashes continuously after 10 sec-
onds. However, the interior motion
sensor is not activated.
>If the indicator lamp goes out when
the system is disarmed: No manipu-
lation or attempted intrusions have
been detected in the period since the
system was armed.460de105

For your personal safety when adjusting
the seat position, please follow the in-
structions below carefully:
Never try to adjust your seat while
operating the vehicle. The seat
could respond with an unexpected
movement, and the ensuing loss of ve-
hicle control could lead to an accident.
Be sure that the safety belt remains
firmly against your body at all times. In
the event of a frontal impact, a loose lap
belt could slide over the hips, leading to
abdominal injury. In addition, the safety
belt's restraint effectiveness is reduced
if the belt is worn loosely.
Never ride with the backrest reclined to
an extreme angle (especially important
for the front passenger to remember).
If you do so, there is a risk that you will
slide under the safety belt in an acci-
dent, thus reducing the protection pro-
vided by the safety belt.<

Airbags Child restraints
*
This is the right way for a larger child to
sit wearing the safety belt when rear
side airbags (arrow) are provided.462us013
Commercially available child seats
complying with the legal standard are
designed to be secured with a lap belt
or with the lap belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint sys-
tems can increase the risk of injury to
children. Always read and follow the in-
structions that come with the system.380us123
If you use a child restraint system with a
tether strap, three additional tether an-
chorage points (refer to the arrows in
the illustration) have been provided.
Depending on the location selected for
seating in the rear passenger area, at-
tach the tether strap to the correspond-
ing anchorage point to secure the child
restraint system. Remove the cover first
on the middle location.
If the respective seating position is fit-
ted with a headrest lift the headrest and
pass the tether strap between the
headrest and the seat back.
Adjust the tether strap according to the
child restraint manufacturer's instruc-
tions.
Before installing any child restraint
device or child seat, please read
the following:
Never install a rearward-facing child re-
straint system in the front passenger
seat of this car.
Your car is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child restraint system
(of the kind designed for infants under
1 year and 20 lbs.) would be within the
airbag's deployment range, you should
never mount such a device in the front
passenger seat, since the impact of the

Child restraints
*
Installing a child restraint system
airbag against the child restraint's back-
rest could lead to serious or fatal inju-
ries.
If it is necessary for a child (not an in-
fant) to ride in the front seat, certain pre-
cautions 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 airbag and the
child. Older children should be tightly
secured with the safety belt. Younger
children should be secured in an appro-
priate forward-facing child restraint sys-
tem that has first been properly secured
with a safety belt.
Never install a rear-facing child restraint
system in the front passenger seat.
We strongly urge you to carefully read
and comply with the instructions for in-
stallation and use provided by the child
restraint's manufacturer whenever you
use such a device.
Be sure that all occupants (of all ages)
remain properly and securely restrained
at all times.c
All rear seating positions in your vehicle
meet the recommendations of SAE
J1819, an industry recommended prac-
tice for securing child restraint systems
in motor vehicles.All of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child
restraint systems.
Information pertaining to this is located
in the immediate vicinity of the buckle
latch of each safety belt.
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.
The belt cannot be extracted further.
Always comply with the installation
instructions provided by the manufac-
turer of the child restraint system.462us014
Unlock the safety beltRelease the safety belt, remove the
child's seat and pull the safety belt out
to its end position on the belt retractor.

Automatic transmission with Steptronic
*
D Drive (automatic shift program)This position is designed for driving un-
der all normal operating conditions. All
forward gears are available."Kickdown"In the "Kickdown" mode, you achieve
the maximum acceleration and the top
speed in position D.
To activate this mode, depress the ac-
celerator pedal beyond the full-throttle
position, at which a resistance point
must be overcome.
M/S Manual operation and
Sport ProgramShifting from D into M/S activates the
Sport Program. This is indicated by
"SD" in the gear selection display. This
position is recommended for a perfor-
mance-oriented driving style.
With the first brief touch, the automatic
transmission shifts from the Sport Pro-
gram to the manual mode.
When you move the selector lever for-
ward in the "+" direction, the transmis-
sion shifts up. When the lever is moved
back in the "Ð" direction, the transmis-
sion shifts down. M1 to M5 appear in
the gear indicator.460de145
Upshifts or downshifts will only be car-
ried out by the ATC at appropriate en-
gine speeds and road speeds. If the en-
gine speed is too high, for instance, a
downshift will not be executed. The gear
selected will appear briefly in the instru-
ment cluster followed by the current
gear.
To accelerate quickly in the man-
ual mode (to pass another vehicle,
for instance), 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.

Through-loading system
*
The rear backrest is divided into two
sections (one-third and two-thirds of the
width of the seat). For carrying longer
objects, you can fold down either
section of the backrest separately.
To unlock, pull the lever corresponding
to the section (arrow).460de154
The rear backrest section will move
forward slightly when it is unlocked.
Reach into the gap and pull the back-
rest down.
When you close the backrest, be
sure that the retainer engages
correctly. If it is not correctly engaged,
transported cargo could enter the pas-
senger compartment from the luggage
compartment during brake applications
or evasive maneuvers and endanger the
vehicle occupants.<460de153
The fittings at the corners of the lug-
gage compartment provide you with a
convenient means of attaching luggage
nets
* and flexible straps for securing
suitcases and luggage.
Refer also to "Cargo loading" on
page 99.

Ski bag
*
The ski bag allows the safe and clean
transport of four pairs of skis or two
snowboards.
The length of the ski bag and the addi-
tional space provided in the luggage
compartment make it possible to carry
skis with a length of up to 6.8 feet
(2.1 meters). The ski bag can only
accommodate two pairs of skis with a
length of 6.8 feet (2.1 meters) because
of the tapered shape of the bag.
Loading1 Pull the center armrest down. Loosen
the trim from the upper Velcro¨ fas-
tener and place it on the armrest.
2 Press button 1 downward and swing
the cover forward.
3 Extend the ski bag between the front
seats. The zipper provides conve-
nient access to stored items. It may
be opened to allow the ski bag to dry.
4 Press knob 2: The cover in the lug-
gage compartment is unlocked.
To store the ski bag, perform the above
steps in reverse sequence.394de119
Securing the load
Secure the skis or other objects in
the bag by tightening the strap
with the buckle.<
Please be sure that your skis are clean
before loading them into the bag. Avoid
damage from sharp edges during load-
ing.

Cargo loadingStowing cargo If you are transporting a load in your
BMW
>Load heavy cargo as far forward as
possible Ð directly behind the back-
rests or the luggage compartment
partition Ð and as low as possible.
>Cover sharp edges and corners.
>Do not pile objects higher than the
top edge of the backrest.460de160
>If you are transporting very heavy
loads when the rear seat is not occu-
pied, secure the outer safety belts in
the opposite buckles (refer to the
illustration).460de185
Securing the load >For small, light items, use the rubber-
lined non-skid side of the floor mat or
secure with a luggage compartment
net
* or elastic straps (refer to
page 41).
>For large, heavy pieces, see your
BMW center for load-securing de-
vices*. Lashing eyes (arrow) are pro-
vided at the corners of the luggage
compartment for attaching these
load-securing devices.
>Comply with the information en-
closed with the load-securing de-
vices.

Cargo loading Roof-mounted luggage rack
*
Always position and secure the
load correctly. If you do not, it can
endanger the passengers during brak-
ing or evasive maneuvers.
Do not exceed the permissible gross
vehicle weight and the permissible axle
loads (refer to page 174). If you do, the
operating safety of the vehicle is no
longer ensured and you are in violation
of the law.
Do not carry hard or heavy objects un-
secured in the passenger compartment.
If you do so, they may be projected
through the air during braking and eva-
sive maneuvers, thus endangering vehi-
cle occupants.<
AnchorsAccess to the anchors:
To open the cover (arrow), please use
the tool included with the luggage rack
system.
A special roof-rack system is available
for your BMW as an optional extra.
Please comply with the precautions in-
cluded with the installation instructions.
Because roof racks raise the center of
gravity of the car when loaded, they
exercise a major effect on its handling
and steering response.
You should therefore always remember
not to exceed the approved roof weight,
the approved gross vehicle weight or
the axle weights when loading the rack.
You will find the specifications under
"Technical Data" on page 174.462de271
Make sure that the load is not too heavy,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Be sure that adequate
clearance is maintained for raising the
sliding/tilt sunroof
*, and that objects do
not project into the opening path of the
luggage compartment lid.
Secure the roof luggage correctly and
securely to prevent it from shifting or
being lost during driving (danger to fol-
lowing traffic).
Drive smoothly and avoid sudden ac-
celeration or braking. Do not corner at
high speeds.
The roof load increases the aerody-
namic resistance. Increased fuel con-
sumption and additional stresses on the
vehicle's body result from this.
