Installing a 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.
Information regarding this is located
near the buckle latch of each safety
belt.46cus027
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 farther.
Always comply with the installation
instructions provided by the manufac-
turer of the child restraint system.
To release the beltRelease the buckle, remove the child-
restraint device and allow the belt
retractor to reel the belt completely in.

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
maximum performance and the top
speed in position "D".
To activate this mode, depress the ac-
celerator pedal beyond the full-throttle
position, going beyond the point of re-
sistance.
M/S Manual mode 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 "–" direction, the transmis-
sion shifts down. M1 to M5 appear in
the gear indicator.46cde054
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
instrument cluster followed by the cur-
rent gear.
To accelerate quickly in the man-
ual mode (to pass another vehi-
cle), 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.

Ski bag
*
The ski bag allows the safe and clean
transport of up to three 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 0 meters). Because of the tapered
shape of the bag, the ski bag can only
accommodate two pairs of skis that are
6.8 feet long (2.1 0 meters).
Loading1 Release the safety belts from their
holders
2 Press down on the button (arrow) and
remove the fill piece by pulling it for-
ward
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 dry46cde066
To re-attach the fill piece, guide
the tabs into the strip of molding
and snap the fill piece back into place.
The safety belts can then be re-secured
into their holders.<

Cargo loading
4 Press the button in the luggage com-
partment (arrow)
5 Use the magnetic retainer to fasten
the cover panel to the back wall.Securing the load
Secure the skis or other objects in
the bag by tightening down the re-
taining strap at the buckle.<
Please ensure that the skis are clean
before loading them into the bag. Take
care to avoid damage from sharp
edges.
46cde065
Stowing cargo If you are transporting a load in your
BMW:
>Load heavy cargo as far forward as
possible – directly behind the back-
rests or the luggage compartment
partition – and as low as possible
>Cover sharp edges and corners.46cde063
To enlarge the luggage compart-
ment when the convertible top is
closed, refer to page 41.
We recommend that you always fold
the convertible top compartment panel
down as soon as you have unloaded
the luggage compartment. That way
you will always be sure of being able to
operate the convertible top at any time.
Reverse the process by flipping the
convertible top compartment panel up
before stowing any cargo in the lug-
gage compartment, which will (also)
prevent any damage to the convertible
top compartment or the cargo.<

lined non-skid side of the floor mat or
secure with a luggage compartment
net
* or elastic straps (refer to
page 40)
>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 enclosed
with the load-securing devices.

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 184). If you do, safe
operation 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.<

Luggage rack for the hardtop
*
Mounting pointsAccess to the mounting points:
To open the covers (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 observe the precautions in-
cluded with the installation instructions.
Because roof racks raise the center of
gravity of the vehicle 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 184.46cde097
Make sure that the load is not too heavy,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Make sure nothing projects
into the luggage compartment lid's
opening and closing path.
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 aerodynamic
resistance, resulting in increased fuel
consumption and additional stresses on
the vehicle body.

Antilock Brake System (ABS)The concept ABS enhances active driving safety
by helping to prevent the wheels from
locking while braking. This is because
locked wheels are dangerous. When
the front wheels slide, the driver loses
steering control over the vehicle.
Traction loss at the rear wheels can
cause the rear end to break into an
uncontrolled skid.
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability
>To help maintain steering control and
maneuverability – on all types of road
surfaces (asphalt, concrete, mud, wet
road surfaces, snow, ice).
The system can achieve the shortest
braking distances possible under most
conditions (on straight aways and in
curves, on asphalt, ice, wet road sur-
faces, etc.).
Braking with ABSThe system is operative once the vehi-
cle exceeds a speed of approx. 6 mph
(10 km/h). It is deactivated once again
below approx. 4 mph (6 km/h). This
means that the wheels can lock in the
final phase of a panic stop – a factor of
no significance in actual use.
If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum brake pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a mini-
mum of steering effort.
The ABS closed-loop control circuit
cycles in fractions of a second. A pulsa-
tion at the brake pedal, together with
the sounds associated with the hydrau-
lic controls, tells you that the brake sys-
tem is within its maximum limit range,
and reminds you that you should adapt
road speed to the road conditions.
On road surfaces that have a loose
surface layer on a firm base with good
traction (on gravel or snow, for exam-
ple), or when snow chains are mounted,
braking distances may be longer than
with locked wheels. However, ABS continues to provide
enhanced vehicle stability and steering
response under these conditions.
Information for your safetyNot even ABS can suspend the laws of
physics. ABS cannot prevent the conse-
quences of brake applications with inad-
equate clearances for safety between
vehicles, when exceeding the speed
limit in curves, or the risks involved
when aquaplaning occurs. Responsibil-
ity for these types of situations remains
in the hands (and at the feet) of the
driver. You should never allow the
added safety of ABS to lull you into a
false sense of security, or mislead you
into taking increased risks that could
affect your own safety and that of others.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<

To unlock Pull the lever located under the left-
hand side of the dashboard.
Do not work on your vehicle with-
out appropriate skills. Always
switch off the engine and allow it to
cool down before working in the engine
compartment. Always disconnect the
battery before working on any electrical
systems or equipment, especially when
these are located within the engine
compartment. Comply with all applica-
ble instructions and warnings. Failure to
work in an informed, professional man-
ner when servicing components and
materials constitutes a safety hazard
for vehicle occupants and other road
users. If you are not familiar with the
guidelines, please have the operations
performed by your BMW center.<460us012

Caring for your vehicleThe buildup of an electrostatic charge
on the seat covers, particularly if atmo-
spheric humidity is low, can give the
occupants an unpleasant electric shock
if they touch metal body parts after leav-
ing the vehicle. Although this not dan-
gerous in any way, it can be avoided by
touching a bare or polished metal part
of the vehicle while getting out.Leather care The leather upholstery
* used by BMW
is a natural product of the highest qual-
ity, processed using state-of-the-art
methods to ensure that it will maintain
its high quality for years to come, pro-
vided that it is properly cared for.
Because this product is manufactured
using natural materials, you must make
allowance for its special characteristics
and for the peculiarities of its use
and care.
Regular periodic cleaning and care are
essential, as dust and road dirt act as
abrasives in the pores and creases of
the material. This leads to wear spots
and premature brittleness on the sur-
face of the leather. We therefore sug-
gest that you clean the leather with a
vacuum cleaner or cloth at frequent
intervals.For cleaning, use BMW leather
cleaning foam.
Since dirt and grease gradually attack
the protective layer of the leather, the
cleaned surfaces should be treated
with BMW leather care agent. This also
acts as an antistatic agent.
For protection against dampness or
moisture, treat the leather with an im-
pregnating agent made by BMW.
We recommend that you perform this
procedure twice a year on leather
exposed to normal use.
Spills should be wiped up immediately.
Remove grease and oil stains by dab-
bing with spot remover. Avoid rubbing.
If the upholstery is to be exposed to in-
tense sunlight or if the vehicle is to be
stored for an extended period, cover all
leather surfaces (or, better yet, the win-
dows) to prevent fading.
Use the cleaning and car-care
products available at your BMW
center.<
Cleaning agents can contain sub-
stances that are dangerous or
pose health risks. For this reason,
always comply with the warnings and
danger labels on the packaging.
When cleaning the vehicle's interior,
open the doors or windows (if the con-
vertible top has been closed). Never
clean your vehicle with solvents or
other materials not specifically in-
tended for this purpose.<
