Disc brakesDisc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
discs and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
discs by brake applications is not
reached.
If the brake discs are corroded, they will
tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: use only
brake pads that BMW has
approved for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Driving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Be aware of traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat which is generated by the brake
applications helps to dry the brake
pads and discs.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the
antilock brake system ever fails, you
should revert to pumping the brakes
(refer to page 128).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible
impairment of the braking effect.
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear. When
driving a vehicle with automatic trans-
mission, you can still downshift into first
gear. Refer to page 74.If engine braking should prove to be
inadequate, you should still avoid
extended, continuous braking. Instead
of maintaining low to moderate pres-
sure over an extended period of time,
you should decelerate by applying
more substantial pressure to the brake
pedal (watch for following traffic),
releasing the pedal, and then repeating
the application (staggered braking). The
cooling phases between active braking
intervals prevent the brakes from over-
heating, thus ensuring that full braking
capacity remains available at all times.
Do not coast with the clutch
depressed or with the shift lever
or selector lever in Neutral. Do not drive
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed or the transmission
is in Neutral, and there is no power-
assist for braking or steering when the
engine is not running. Never allow floor
mats, carpets or any other objects to
protrude into the area around the brake,
clutch or accelerator pedals, which can
obstruct pedal travel.<

Brake systemBrake fluid level
The brake warning lamp comes
on with the parking brake
released:
The brake fluid level is too low in the
reservoir (refer to page 148).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the hydraulic circuits of the
brake system.
Brake warning lamp for Cana-
dian models.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
The brake pads warning lamp
lights up:
Only the minimum pad thick-
ness still remains on the brake pads.
Proceed to the nearest BMW center
as soon as possible to have the pads
replaced.
For your own safety: use only
brake pads that BMW has
approved for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Caring for your vehicleCaring for the vehicle's finish Regular washing is a preventive
measure against long-term effects from
substances that are harmful to the
vehicle's finish, especially if you drive
your vehicle in areas with high levels of
air pollution or aggressive natural
substances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive sub-
stances. Failure to do so can lead to
changes in the paint's chemical
structure or to discoloration. Gasoline
spilled during refueling, oil, grease and
brake fluid should always be cleaned
away immediately, as should bird
droppings.
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use clean-
ing fluid or alcohol with a clean cloth
or cotton pad to remove. Remove tar
spots with tar remover. After cleaning,
the affected areas should be waxed to
ensure continued protection.
Use the cleaning and car-care
products available at your BMW
center.<
Waxing your vehicle Protect the finish using carnauba or
synthetic-based waxes only.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the
surface.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Use the cleaning and car-care
products available at your BMW
center.<
Paint damageYou can touch up small areas of paint
damage with a BMW spray paint or a
BMW touchup stick.
The paint color code for your vehicle
is provided on a sticker located on the
right hand-side under the hood and
on the first page of your Service and
Warranty Information Booklet
(US models) or Warranty and Service
Guide Booklet (Canadian models).
Damage caused by flying stones,
scratches, etc., must be touched up
without delay to prevent rust from
forming.
If corrosion has started to form in an
area with paint damage, remove all rust
and clean the area. Then prime the area
with a BMW Primer Stick. Finally, apply
the finish coat. Wait a few days, then
polish the repaired area. Finish by
applying a wax preservative.
More extensive paint damage should
be repaired professionally in accor-
dance with the manufacturer's instruc-
tions. Your BMW center uses original
BMW finish materials in accordance
with approved repair procedures.

Cleaning and care of the convertible topCareThe appearance and life of the convert-
ible top are highly dependent on its
proper care and operation. You should
pay particular attention to the following
instructions if your car has a light-
colored top.
Protect the vehicle from exposure to
intense sunlight whenever possible by
parking it in the shade. This will help to
prevent the paint, rubber and fabric-
covered parts from being worn out.
Never stow the convertible top in the
convertible top compartment when it is
wet, dirty or frozen, since this can
cause mildew stains and chafe marks.
To prevent mildew stains, do not keep
the convertible top enclosed in the
convertible top compartment for any
extended period of time.
If the vehicle will be parked for lengthy
periods in an enclosed space, be sure
that the convertible top is dry and that
there is adequate ventilation.
Clean off bird droppings immediately,
since they attack the convertible top
and cause the rubber seals to swell due
to their caustic characteristics.Besides water, treat rubber seals only
with talcum powder, rubber care prod-
ucts or silicone spray, particularly when
they feel dry or tend to stick.
Eliminate noises such as squeaks with
lubricant spray.
Depressions and discoloration may
occur in the convertible top as a result
of improper maintenance and cleaning
or due to loading from excessive use.
The convertible top and its seams may
also develop leaks. These occurrences
are not covered by the warranty. For
repairs, please consult your BMW
center.
Washing your carYou can wash your BMW at an auto-
matic car wash. Brushless systems are
preferable.
If a brushless car wash is unavailable
and a brush car wash must be used,
modern systems with soft brushes are
preferable. Do not select the wax finish
option. The small amount of beading
wax always used in automatic car
washes will not harm your vehicle's
finish.
In the case of more extensive dirt,
which is definitely visible on light-
colored top materials, clean the top
with the BMW Convertible Cleaning
Set. Please proceed as follows:
Spray the convertible top with the
cleaning agent and then rub with a
well-dampened sponge using circular
motions until a foam develops. Then
you can finish washing the vehicle in an
automatic car wash. After washing your
vehicle 3 to 5 times, you should treat
the convertible top with a special
convertible top impregnating spray.
Please follow the instructions on the
spray can.

Changing a wheel9 Position the new wheel or the
space-saver spare tire on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes.
10 Screw in the remaining lug bolts.
Tighten all the bolts securely.
11 Lower the jack and remove it from
beneath the vehicle.
12 Tighten the lug bolts in a diagonal
pattern.462de266
13 If your wheels are equipped with full
wheel covers
*: position the wheel
cover with the valve opening over
the valve (arrow) and press it onto
the wheel with both hands.
14 Check and correct the tire's inflation
pressure at the earliest possibility.
For vehicles with Tire
Pressure Control (RDC):
Reactivate the system after
mounting the space-saver spare tire
or after correcting the air pressure.
Refer to page 91.
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire since this could
damage the cover.<
462de279
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated lug wrench [torque specifi-
cation: 72 lb.ft (100Nm)] at the earliest
opportunity.<
When storing the wheel, be sure that
you do not damage the retaining pin in
the spare tire recess.
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
