Special operating instructions
76 sure which must be exerted by the pads to
clean the rotors by brake applications is not
reached.
If the brake rotors are corroded, they will tend to
respond to braking with a pulsating effect which
even extended application will fail to cure.
Brake pads
The warning lamp lights up. The brake
pads have worn down to the minimum
safe limit. Have the brake pads
replaced as soon as possible.
When the vehicle is parked
Condensation forms while the air conditioning
or automatic climate control is in operation, and
then exits under the vehicle. Traces of con-
densed water on the ground underneath the
vehicle are thus normal.
Before driving into a car wash
For general information about taking care of
your BMW, refer to the Caring for your vehicle
brochure.
Cargo loading
Avoid overloading the vehicle so that the
permissible carrying capacity of the tires
is not exceeded. Otherwise, overheating and
inner damage to the tires may result. The ulti-
mate result can assume the form of a sudden air
loss.<
Determining the maximum load
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
2.Determine the combined weight of the
driver and passenger that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passenger from XXX kilograms or
YYY pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
551 lbs and there will be two 150 lbs occu-
pants in your vehicle, the amount of avail-
able cargo and luggage load capacity is
251 lbs.
551 lbs minus 300 lbs = 251 lbs
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.

Load
The permissible load is the sum of the occu-
pants' weights and the weight of the cargo. The
greater the weight of the occupants, the less
cargo can be transported.
Stowing cargo
>Load heavy cargo as far forward as possi-
ble, directly behind the cargo bay partition,
and as low as possible.
>Cover sharp edges and corners.
To avoid damaging the rear of the back-
rests or the rear interior trim panel, do not
stow heavy cargo or cargo with sharp edges
and corners behind the seats.
In addition, large and bulky cargo stowed
behind a seat may prevent the backrest from
engaging properly. Therefore, check the back-
rest to see if it is properly engaged, and move
the seat forward if necessary; refer to page31.
Always position and secure the load as
described above. If you do not, it can endanger
the occupants during braking or evasive
maneuvers.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page113, as excessive loads can pose a
safety hazard, and may also place you in viola-tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants.<
Roadster: convertible top
compartment
The cargo bay can be enlarged when the
convertible top is closed, refer to page23.
I t i s r e c o m m e n d ed t h a t y o u a lw a y s f o l d t h e c o n -
vertible top compartment panel down as soon
as you have taken your cargo out of the cargo
bay. This way, you can be sure that you can
always operate the convertible top at any time.
When the convertible top is closed, fold the
convertible top compartment panel up before
stowing your cargo in the cargo bay, to avoid
any damage to the convertible top compart-
ment or your load.
Do not stow any items on the convertible top
compartment panel, otherwise the convertible
top could be damaged while it is opening.<
If you stow cargo behind the seats of your
BMW:
>Only stow light objects such as clothing,
etc.
>Do not pile objects higher than the top edge
of the backrests.
Roadster: hardtop
preparation*
Pull covers off, see arrow1.
The brackets for attaching the hardtop
are located underneath the covers; see arrow2.

the gas cap is loose or missing. Close
the gas cap properly.
Manually releasing the fuel filler door
In the event of a malfunction you can unlock the
fuel filler door manually.1.Remove the cover for the right-hand rear
lamps in the cargo bay by turning the lock,
see arrow.
2.Pull the cargo bay trim panel slightly toward
the interior. The green button with the fuel
pump symbol becomes visible.
3.Undo the adhesive strip and pull off.
4.Pull the button. The fuel filler door is
released.
Pull on the button slowly and care-
fully; otherwise it could be torn off.<
Observe the following when refueling
When handling fuels, comply with all of
the applicable safety precautions posted
at the service station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as it could other-
wise lead to:
>Premature pump shutoff
>A reduced efficiency of the fuel-vapor
recovery system.

Correct wheels and tires
BMW recommends using only wheels
and tires that have been approved by
BMW for your particular vehicle model, other-
wise body contact and serious accidents can
result despite the use of the same nominal size,
e.g. due to manufacturing tolerances. If non-
approved wheels and tires are used, BMW can-
not evaluate their suitability, and therefore can-
not be held liable for driving safety.<
You can inquire about the correct wheel/tire
combination at your BMW center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS and DSC.
To maintain good handling and vehicle
response, only use tires of a single brand and
tread configuration. After a tire has been dam-
aged, for instance, mount the original wheel and
tire combination again as soon as possible.
Wheels with electronics for the Tire
Pressure Monitor TPM
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPMS electronics; otherwise the
Tire Pressure Monitor would not be able to
detect a flat tire, refer to page54. Your BMW
center will be glad to provide you with more
information.
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Run-Flat Tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, moreover, no spare wheel is
available. Your BMW BMW center will be glad to
provide you with more information.
For safety reasons, BMW recommends
that damaged Run-Flat Tires be replaced
rather than repaired.<
Special characteristics of winter tires
BMW recommends the use of winter tires for
operation under winter road conditions. While
all-season tires with M+S designation provide
better winter traction than summer tires, they
generally do not achieve the full performance of
winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Store tires in a cool, dry place, protecting them
against light whenever possible. Protect the
tires from contact with oil, grease and fuel. Do
not exceed the maximum tire inflation pressure
indicated on the sidewall of the tire.
Swapping wheels between the axles
BMW advises against moving the front wheels
to the rear wheel positions and vice versa, as
this may impair vehicle handling characteristics.

Adding engine oil
Do not add the maximum amount of 1 US quart/
1 liter of engine oil until the warning lamp lights
up in the instrument cluster, refer to page92, or
until the oil level monitor shows "+1.0".
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the warnings on
the containers. Otherwise, health hazards may
result.<
Oil change
Have your oil changed only by a BMW center or
a workshop that works according to BMW
requirements with the appropriately trained
personnel.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. BMW
continuously approves specific oils after con-
firming their suitability for use in its vehicles
with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or other approved syn-
thetic oils.
www.bmwusa.com to obtain this information.
Do not use any oil additives, as they could
cause engine damage under some cir-
cumstances.<
Viscosity classes
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 5W-40 and
5W-30 classes.<
These oils can be used for driving at all outside
temperatures.
Coolant
Warning lamp
The warning lamp lights up:
The coolant level is too low. Top up the
coolant as soon as possible.
Do not open the cooling system when the
engine is hot. If you do, escaping coolant
can cause burns.<
Coolant consists of water and coolant additives.
Not all commercially available additives are suit-
able for your BMW. Your BMW center knows
which additives are appropriate.
Only use approved additives, otherwise
the engine could be damaged. The addi-
tives are hazardous to health.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking the coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated

pressure to escape, then continue turning
to open.
3.The coolant level is correct if the upper end
of the red float spindle is at least at the same
level as the upper edge of the filler neck but
no more than 3/4 in or 2 cm above it, i.e. up
to the mark on the float spindle. Refer also
to the diagram next to the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.Twist the cap back on and tighten it firmly.
6.Have the cause for the coolant loss
removed as soon as possible.

Exhaust emission values
The warning lamp lights up: the
exhaust emission values have wors-
ened. Have the car checked as soon as
possible.
The lamps flash under certain conditions. This
indicates excessive misfiring of the engine. If
this happens, you should reduce your speed
and visit your nearest BMW center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.
Canadian models display this warning
lamp.
The warning lamp lights up if the gas
cap is not properly tightened and the
OBD system can assume that fuel
vapor is escaping. If the gas cap is then tight-
ened, the warning lamp should go out within a
few days.
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore, be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Do not touch the glass portion of a new
bulb with your bare hands since even
small amounts of impurities burn into the sur-
face and reduce the service life of the bulb. Use
a clean cloth, paper napkin or a similar material,
or hold the bulb by its metallic base.<
A replacement bulb set is available from your
BMW center.
When working on electrical systems,
always begin by switching off the corre-
sponding consumers, otherwise short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, be sure to
observe any instructions provided by the bulb
manufacturer.<
For care and maintenance of the headlamps,
please follow the instructions in the separate
Caring for your vehicle brochure.
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LEDs
Control elements, display units and other inte-
rior equipment in your vehicle use a light-emit-
ting diode behind a cover as a light source.
These light-emitting diodes, which operate
using a concept similar to that applied in con-
ventional lasers, are officially designated as
Class 1 light-emitting diodes.
Do not remove the covers, and do not
look directly at the unfiltered light for sev-
eral hours. Otherwise, your eyes could suffer
irritation of the retina.<
