To closeThe handle recesses in the interior trim
panel of the luggage compartment lid –
see arrows – make it easier to pull the
lid down.
To avoid injuries, be sure that the
travel path of the luggage com-
partment lid is clear when it is closed,
following the same precautions as with
all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
closed. Otherwise, exhaust fumes
could penetrate the interior of the vehi-
cle. <
Should it be absolutely necessary to
operate the vehicle with the luggage
compartment lid open, with closed con-
vertible top:
1. Close all windows
2. Greatly increase the quantity of air
coming from the air conditioning or
automatic climate control system,
see page 100 or 104.
Emergency releaseThis lever releases the luggage com-
partment lid from inside the luggage
compartment.

52To adjust
Safe seating positionFor relaxed and fatigue-free driving you
should select a sitting position that
reflects your personal requirements. In
combination with the safety belts and
airbags, the correct seating position
plays an important role in enhancing
occupant safety in the event of an acci-
dent. To ensure that the vehicle's safety
systems provide you with optimal pro-
tection, we request that you direct your
careful attention to the following sec-
tion.
For supplementary information on
transporting children, refer to page 63.Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the
airbags. Always hold the steering wheel
by the rim to keep any chance of injury
to hands or arms to an absolute mini-
mum should the airbag be deployed.
Never allow any objects, individuals or
animals to obstruct the areas between
passengers and airbags. Never use the
front airbag's cover as a storage tray or
support for objects of any kind. Never
allow front passengers to rest their feet
or legs on the airbag cover.<
For airbag locations and additional
information on airbags, refer to
page 61.Sitting safely with safety belts
Never allow more than one person
to wear a single safety belt. Never
allow infants or small children to ride in
a passenger's lap. Avoid twisting the
belt while routing it firmly across the
hips and shoulder, wear it as snugly
against your body as possible. Do not
allow the belt to rest against hard or
fragile objects. Do not route the belt
across your neck, or run it across sharp
edges. Be sure that the belt does not
become caught or jammed. Avoid
wearing bulky clothing and pull on the
lap belt periodically to retension it over
your shoulders. In the event of a frontal
impact, a loose lap belt could slide over
your hips, leading to abdominal injury.
In addition, the safety belt's restraint
effectiveness is reduced if it is worn
loosely. Expectant mothers should
always wear their safety belts, taking
care to position the lap belt against the
lower hips, where it will not exert pres-
sure against the abdominal area.<
For information on using the safety
belts, refer to page 56.
SeatsWhen adjusting your seat, always
observe the following precautions
Never try to adjust your seat while
operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident. Never
ride with the backrest reclined to an
extreme angle. This is especially impor-
tant for the front passenger to remem-
ber. If you do so, there is a risk that you
will slide under the safety belt in an
accident, thus reducing the protection
provided by the safety belt.
With the wind deflector in place:
To avoid damaging the wind deflector
never push the front seats all the way
back.<

3. Keep pressing down on the protec-
tive bar – see arrow 1 – from on top
until you hear it click into place
4. Put the cover panel back in place
and press down firmly
5. Push the back panel of the head
restraint closed – see arrow 2.
Do the same for the second protective
bar. If you are not familiar with any of
the procedures, consult your BMW
center.
Have the rollover protection system
checked out by your BMW center after
it has been inadvertently triggered.
Do not move the convertible top
under any circumstances if the
rollover protection system has
extended.
Do not use the rear head restraints as
storage shelves.
Absolutely no modifications are to be
made to any of the rollover protection
system's individual components or any
of its wiring.
Only your BMW center is to carry out
any work on the rollover protection sys-
tem.
Work done on the system that is carried
out improperly could lead to failure in
an emergency or accidental activation.
Regarding having the system checked
to ensure long-term operation: be scru-
pulous in adhering to the Service inter-
val display for maintenance intervals.
Every 2 years at the latest, the rollover
protection system must be inspected at
a BMW center.<

Driving notes
Brakes: do not drive with your foot
resting on the brake pedal. Even
light but consistent pedal pressure can
lead to high temperatures, brake wear
and possibly even brake failure.
Hydroplaning: when driving on wet or
slushy roads, reduce vehicle speed. If
you do not, a wedge of water may form
between the tires and the road surface.
This phenomenon can lead to partial or
complete loss of contact between the
tires and road surface, as well as loss of
vehicle control and braking ability.
Driving through water: do not drive
through water on the road if it is deeper
than 1 ft/30 cm, and then only at walk-
ing speed. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.
Clothes hooks, with hardtop: when
hanging clothing from the hooks, be
sure that they will not obstruct the
driver's vision. Do not hang heavy
objects on the hooks. If you do so, they
could cause personal injury during
braking or evasive maneuvers.<
Antilock Brake System (ABS)The conceptABS keeps the wheels from locking
during braking, thereby enhancing
active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of ABS system if you apply maximum
pedal pressure – panic stop.
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.Dynamic Brake Control (DBC)DBC is included in the DSC, refer to
page 90. The system responds to sud-
den, high-intensity applications of force
to the brake pedal by automatically
braking the vehicle with maximum
boost to achieve the shortest possible
braking distances during panic stops.
This system also exploits the benefits of
ABS. Do not reduce the pressure exerted against the brake pedal until
the braking maneuver has been com-
pleted. DBC is deactivated when you
release the brake pedal.
Cornering Brake Control (CBC)CBC is an advanced engineering devel-
opment of ABS. When braking during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is improved
and the steering response is enhanced.

Hardtop*It is not necessary to remove the fabric
top even in the winter, when the hard-
top is generally in constant use. But you
can also remove it easily at any time.
Before the fabric top is stored in the
convertible top compartment, it must
be absolutely dry in order to avoid
water spots and mildew from forming.
The hardtop offers reading lamps and
clothes hooks that can be used just by
pressing. It is also possible to mount a
luggage rack on the roof. Please con-
sult your BMW center.
When hanging clothing from the
hooks, be sure that they will not
obstruct the driver's vision. Do not hang
heavy objects on the hooks. If you do
so, they could cause personal injury
during braking or evasive maneuvers.<
Two people are required for installation
or removal. Work with extreme caution
in order to avoid paint damage and
damage to the body or hardtop.
To facilitate hardtop installation or
removal, you can obtain a specially
designed hardtop lift* or hardtop rack*
at your BMW center.
Storage
Storing the hardtop on the floor:
slide the styrofoam block that
came with the hardtop onto its center.
The arrow on top of the styrofoam block
has to be pointing upward when you
are doing this.<
Installation1. Lower the side windows com-
pletely and flip the sun blinds
down. If necessary, remove the
antenna rod to avoid any damage
2. On vehicles with manual convert-
ible top operation, first release the
convertible top compartment lid,
and, if necessary, open it some-
what. On vehicles with fully-auto-
matic convertible top operation,
open the convertible top compart-
ment lid slightly by pressing the
button for the operation of the con-
vertible top
3. Remove the trim pieces on both
sides by pulling them off toward
the back – see arrow – and reclose
the convertible top compartment
lid

Wheel and tire combinationsThe right choice
BMW recommends using only
wheels and tires that have been
approved by BMW for your particular
vehicle model, as otherwise body con-
tact and serious accidents can result
despite the use of the same nominal
size, e.g. due to manufacturing toler-
ances. BMW cannot evaluate all tires
and wheels on the market, and is thus
unable to guarantee that the vehicle will
continue to perform safely if unap-
proved tires and/or wheels are
mounted.<
For each tire size, BMW has assessed
the safe performance of specific tire
brands and approved them for use.
Consult any BMW center for details.
Comply with any local/national regula-
tions, for example by recording the tire
type in the vehicle documents.
The correct wheel and tire combi-
nation affects various systems
that would otherwise be impaired, for
example ABS, ASC+T/DSC and
ADB/DBC.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for exam-
ple, remount the approved wheel and
tire combination as soon as possible.<
StorageStore tires in a cool, dry place, protect-
ing them against light whenever possi-
ble. Protect the tires against contact
with oil, grease and fuel.
Winter tiresChoosing the right tireBMW recommends winter tires – M+S
tires – for operation under inclement
winter driving conditions. While all-sea-
son tires – M+S designation – provide
better winter traction than the corre-
sponding summer tires, they generally
do not achieve the performance of win-
ter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer and
with the same tread configuration on all
four wheels.
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<

Brake fluidIndicator lamp
The brake warning lamp comes
on when the parking brake is
not engaged: the brake fluid
level is too low, refer to page 18.
Parking brake warning lamp for
Canadian models.
Adding brake fluidFor adding brake fluid or for determin-
ing and correcting the cause of brake
fluid loss, consult your BMW center.
Your BMW center is familiar with the
specifications for factory-approved
brake fluids – DOT 4.
Brake fluid loss results in extended
pedal travel. Refer to the information on
page 124.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the brake system's
safety and reliability, have the brake
fluid changed every two years by a
BMW center. Refer also to page 83 and
to the Service and Warranty Information
Booklet for US models or the Warranty
and Service Guide Booklet Booklet for
Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion which is out of reach of children.
Do not spill the brake fluid and do not
fill the brake fluid reservoir beyond the
MAX mark. The brake fluid could ignite
upon contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<

157 Giving and receiving assistance
Jump-startingWhen your battery is discharged you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Only use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles.<
1. The battery in the support vehicle
must also be rated at 12 volts. This
information is provided on the battery
label
2. Stop the engine of the support vehi-
cle and switch off all electrical com-
ponents in both vehicles – except for
the hazard warning flashers of the
support vehicle
3. Make absolutely certain that there is
no contact between the bodywork of
the two vehicles – short circuit haz-
ard
4. The auxiliary jump-starting terminal
located in your BMW's engine com-
partment acts as the positive battery
terminal. The cover of this auxiliary
terminal is marked with a + sign.
Remove by pulling the tab – see
arrow 1.
Start by connecting the jumper cable
from the positive terminal of the dis-
charged battery to the positive termi-
nal of the support battery
5. Then connect the negative terminals
with the other jumper cable. First
connect one end to the negative bat-
tery terminal or to a suitable ground
on the support vehicle. Then connect
the other end to the negative battery
terminal or a suitable ground on the
vehicle being started.
Your BMW is equipped with a special
nut for this purpose – see arrow 2
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
6. Start the engine of the support vehi-
cle and let it run for several minutes
at a slightly elevated engine idle
speed
7. Start the engine of the other vehicle
as usual. If the first start attempt is
not successful, wait a few minutes
before another attempt in order to
allow the discharged battery to
recharge
8. Before disconnecting the jumper
cables, let the engines run for a few
minutes
9. Then disconnect the jumper cables
in reverse sequence.
Depending on the cause of the fault,
have the battery checked and
recharged by your BMW center.
