Brake system Hardtop
*
Disc brakesLimited vehicle use, extended periods
with the vehicle parked or in storage,
and operating conditions in which
braking is restricted to gentle, low-
pressure applications will all increase
the tendency for corrosion to form on
the rotors; this is often accompanied by
a simultaneous accumulation of
contamination on the brake pads. The
pads must exert a certain minimal level
of pressure against the rotors for the
disc brakes' inherent self-cleaning
effect to remain effective.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
When driving in heavy rain and on wet
roads it is useful to apply light pressure
to the brake pedal every few miles.
Monitor traffic conditions to ensure that
this maneuver does not pose a hazard
to you or to other road users. The heat
generated in this process helps dry the
pads and rotors to ensure that your
brake system will respond with undi-
minished efficiency when you need it.
When descending steep hills and
extended grades, downshift to a gear
that will allow you to continue safely with only a minimal amount of braking.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times. Use care to avoid exceeding the
approved engine-speed range, refer to
page 74.
Do not coast with the clutch
depressed or with the transmission
or selector lever in neutral. Do not coast
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed 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 accelerator, clutch and brake
pedals and obstruct their movement.<
Brake pads
For your own safety: use only
brake pads that the manufacturer
has released for your particular vehicle
model. The manufacturer cannot eval-
uate 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.<
It is not necessary to remove the fabric
top even in the winter, when the
hardtop is generally in constant use.
But you can also remove it at any time
with no problem. 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. In addition, a roof-rack can be
mounted, for more information, please
contact your BMW center.
When suspending articles of
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.

OverviewControlsMaintenanceRepairsDataIndex
Tire replacementunder the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of performance
on the laboratory test wheel than the
minimum required by law.
The temperature grade for each
tire is defined for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.< Uniform Tire Quality Grading Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Tread wear 200
Traction AA
Temperature A
Do not use retreaded tires, since
driving safety may be impaired.
This is due to the possible variations in
casing structures and, in some cases,
to their extreme age, which can lead to
a decrease in their durability.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4101 indicates that the tire was
manufactured in week 41 of the year
2001.
Although tires may have a theoretical
service life of up to 10 years, BMW
strongly recommends that you replace
all tires after an absolute maximum of
6 years.
Safety tires
*
Safety tires consist of self-supporting
tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of
pressure drop and driving remains
possible to a restricted degree. The
vehicle is equipped with Tire Pressure
Monitor (RDC) or Flat Tire Monitor,
which indicate a flat tire.
For additional information on Tire Pres-
sure Monitor (RDC) or Flat Tire Monitor
refer to page 83 or 85.
Safety tires are only possible in
conjunction with Tire Pressure
Monitor (RDC) or Flat Tire Monitor.<

Wheel and tire combinationsThe right choice
Never mount wheels and tires that
have not been specifically
approved by BMW for use on your
particular model. Although other wheels
and tires may theoretically have the
same dimensions, variations in factors
such as manufacturing tolerances can
result in contact between tire and body-
work, ultimately leading to serious acci-
dents. BMW can not 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.<
The correct wheel and tire combi-
nation affects various systems
that would otherwise be impaired, for
example ABS, ATC, 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
example, remount the approved wheel
and tire combination as soon as
possible.<

Brake fluidWarning lamp
The brake warning lamp comes
on when the parking brake is
not engaged: the brake fluid
level is too low, refer to page 17.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor 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 results in extended
pedal travel. Refer to the information on
page 109.
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 at a
BMW center, refer to page 75 and to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in original container and in a location
which is out of reach of children.
Do not spill 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.<

Do not use spray starter fluids to start
the engine.
When your battery is discharged you
can used 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. Always 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. Ensure that the battery in the support
vehicle is also rated at 12 volts. This
information is provided on the top of
the battery casing
2. Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories in
both vehicles
3. Make absolutely certain that there is
no contact between the bodywork of
the two vehicles Ð short circuit
hazard
4. Start the engine on the support
vehicle and allow it to run
5. Use one jumper cable (+) to connect
the positive terminal of the battery in
the support vehicle with the auxiliary
positive terminal provided in the
engine compartment of your BMW
(arrow 1). The cover on this auxiliary
terminal is identified by a "+" symbol.
Remove by pulling the tab
6. Next, connect one end of the other
jumper cable (Ð) to either the support
vehicle's negative battery terminal or
a suitable ground on its engine or
bodywork. Connect the other end to
the negative battery terminal or a
suitable ground on the vehicle being
started. There is a special nut on
your BMW (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.<
7. Start the support vehicle's engine
and let it run at an increased idling
speed for a few minutes. Start the
engine on the vehicle needing the
jump-start, and allow it to run 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 recharged by your
BMW center.
