Coolant Brake fluidAdding coolant Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant temper-
ature gauge in the instrument cluster
must be located in the blue zone. If it
is not, there is a danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every four years.The brake warning lamp comes on
when the parking brake has been
released:
Check the brake fluid level and if
necessary, top up to the "MAX" mark.
For adding brake fluid or for deter-
mining 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 can result in extended
pedal travel. Comply with the informa-
tion provided on page 126.
460de128
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
an authorized BMW center. Refer also
to the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models). Brake fluid is hazardous to
health and damages the vehicle's paint.
You should always store it in its original
container and in a location that is
inaccessible to children.
Do not spill the 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
environmental laws regulating
the disposal of brake fluid.<

Caring for your vehicleWe 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
dabbing with spot remover. Avoid
rubbing.
If the upholstery is to be exposed to
intense sunlight or if the vehicle is to be
stored for an extended period, cover all
leather surfaces (or, better yet, the
windows) to prevent fading.
Use the cleaning and car-care
products available at your BMW
center.<
Cleaning agents can contain
substances that are dangerous or
that pose health risks. For this reason,
always comply with the warnings and
danger notices on the packaging.
Open the doors or windows on your
vehicle whenever cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically
intended for this purpose.<

158n
Cleaning and care of the convertible topDo not use spot removers, paint thin-
ners, solvents, gasoline or similar
substances for removing spots from the
convertible top or from the rear
window. These materials destroy the
rubber seals, which will lead to leaks.
Use only BMW-approved cleaners.
Cleaning agents can contain
substances that are dangerous or
pose health risks. Therefore, always
comply with the warnings and danger
notices on the package.
Open the doors or windows on your
vehicle whenever cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically
intended for this purpose.c
Positioning for cleaningIn order to have free access to the
convertible top compartment, lean the
rear convertible top bow against the
convertible top compartment lid (see
illustration).
First release the convertible top
locks, see page 45 or 50.<46cde072

Any BMW center will be glad to inform
you of the advisability, legal require-
ments and factory recommendations
regarding technical modifications on
your vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number and, in some
cases, also the engine number. Light-Emitting Diodes (LEDs)Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. The concept
behind their operation is related to that
employed for lasers.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), as inflammation of the
iris could result.<
California laws require us to state the
following warning:
Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.<

OBD interface socketThe OBD interface socket for onboard
diagnostics is located on the driver's
side, on the left-hand bottom of the
instrument panel and under a cover
panel. The cover is marked with the
letters "OBD".
The purpose of the OBD system is to
assure proper emission control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.460us250
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehicle.
Your system should be checked, how-
ever, at the earliest possible opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW center immediately. Severe
engine misfire over even a short period
of time can seriously damage emission
control components, especially the
catalytic converter.
Service Engine Soon warning
lamp for Canadian models.
If the fuel filler cap is not on tight
enough, the OBD system can
detect leaking vapor and the indicator
will light up. If the fuel filler cap is then
tightened, the indicator will usually go
out after a short period of time.<

Changing a wheel
Take these precautionary
measures if you have either a flat
tire or are changing the tire:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat
surface. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position, remove the key
and engage the steering lock. Shift into
1st or reverse gear (selector lever in
"Park" with automatic transmission) and
engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
Set up a warning triangle
* or portable
hazard warning on the roadside at an
appropriate distance from the rear of
the vehicle. Comply with all safety
guidelines and regulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface (snow, ice, loose
gravel, etc.), as it could slide sideways.
Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. Failure to comply with this
creates a risk of fatal injury.<
Your BMW has a space-saver spare tire
for temporary use to ensure your
mobility.
To remove the space-saver spare
tire, take out the floor panel in the
luggage compartment completely (refer
to page 41).<
You will need the following:In order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Jack (1)
Raise the floor panel in the luggage
compartment (refer to page 41) and
unclip the jack from where it is stored
(arrow).
After use, swing the crank back and
clip into place.
>Wedge (2)

Tire Pressure Control* Self-diagnostics This system regularly checks tire pres-
sure and monitors all four tires even
while driving, so you do not have to.
Behind the valve stem in every wheel,
there is an extended-life electronic chip
that contains a pressure sensor, a
transmitter and a battery. The pressure
is measured in extremely short time
intervals and then transmitted by a
radio signal. If an irregularity is
detected, the transmission rate is
increased.
Located near each wheel and
embedded in the vehicle body is an
antenna that receives signals from the
wheel. A central electronics system
evaluates the quadruple signals and
forwards any changes.
The RDC provides an important contri-
bution to driving safety.46cde078
All
of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically Ð the driver
does not have to perform any extra
operations or adjustments.
The indicator lamps come on brießy
after the ignition has been turned on, for
example.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, etc.) is constantly being analyzed
by electrical measurements in the relays.
In the same manner, the electrical
resistance of the airbag ignition genera-
tors and all of the remaining airbag
components is measured at all times. Any
fault in this system would be detected
immediately by a current ßuctuation that 46cde052
would necessarily accompany it.
The fault
would be indicated immediately by the
airbag warning lamp.
Even after you shut off the engine, the
overall functional status of your vehicle is
monitored. For example, all of the ßaps of
the heating and ventilation system travel
to the nearest limit position. This action
ensures that the system will be able to
provide defrosting, regardless of other
circumstances, e. g. if a malfunction in the
air conditioner/automatic climate control
system
* should occur during the night
while the vehicle is parked.
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating and
ventilation ßaps travel to their limit stops
in both directions. The limit positions and
the return travel paths are checked in this
manner in order to ensure that appro-
priate adjustments for the operating
elements can be made at any time.
You will hear the sounds of the air ßaps as
the air conditioner/automatic climate
control* carries out its self-diagnostic
functions after the ignition has been shut
off. All of the other self-diagnostics func-
tions operate silently in the background.
Any possible faults detected during these
self-diagnostics can be read out and
corrected by your BMW center
during the
next regularly scheduled maintenance.
