124Special operating instructions
Break-in proceduresTo ensure that your vehicle continues to
provide maximum economy throughout
an extended service life, we request
that you devote careful attention to the
following instructions.Engine and differentialThe first 1,250 miles/2,000 km:
Drive at varying engine and road
speeds, but do not exceed an engine
speed of 4,500 rpm or a road speed of
100 mph / 160 km/h.
Always obey all official speed limits.
Do not use full throttle, and avoid
pressing the accelerator beyond the
kickdown point during these initial
miles.
You can then proceed to increase
engine or vehicle speeds once the ini-
tial 1,250 miles/2,000 km have elapsed.TiresOwing to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
We thus ask you to drive with extra care
during the first 200 miles/300 km.
Always obey all official speed limits.
Brake systemApprox. 300 miles/500 km must elapse
before the brake pads and rotors
achieve the optimal pad-surface and
wear patterns required for trouble-free
operation and an extended service life
later on.
To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill, e.g. at a
traffic signal, provided that traffic condi-
tions permit to do so.
You can prevent corrosion in the drums
by periodically repeating this proce-
dure.
The brake lamps do not come on
when the parking brake is set.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine off – when tow-
ing, for example – substantially higher
levels of pedal force will be required to
brake the vehicle.<
ClutchApprox. 300 miles/500 km must elapse
before the clutch starts to operate at
optimum efficiency. Remember to
engage the clutch carefully during this
initial period.After replacing partsFollow the same break-in procedures if
any of the components mentioned
above have to be replaced in the future.

General driving notesHot exhaust system
High temperatures occur with
every vehicle equipped with a cat-
alytic converter. Heat shields are
installed adjacent to some sections of
the exhaust system. Never remove
these shields; do not apply undercoat-
ing to their surfaces. When driving,
standing at idle and parking the vehicle,
take care to avoid contact between the
hot exhaust system and flammable
materials, e.g. hay, leaves, grass, etc.
Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
Parking the vehicleCondensation forms in the air condi-
tioner system during operation, which
then exits under the vehicle. It is thus
not unusual for a small puddle to form
under the car while the system is run-
ning.Before driving through a car washFold in the exterior mirrors manually
because they could otherwise be dam-
aged due to the width of the vehicle.
Hydroplaning
When driving on wet or slushy
roads, reduce vehicle speed. If
you do not, a wedge of water may form
between tire and road surface. This
phenomenon is referred to as hydro-
planing, and can lead to partial or com-
plete loss of traction, vehicle control
and braking effectiveness.<
The risk of hydroplaning increases as
the tread depth of the tires decreases,
refer also to Tire tread on page 135.
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed. Other-
wise, the vehicle's engine, the electrical
systems and the transmission may be
damaged.<
Braking safelyYour BMW is equipped with ABS as a
standard feature. If you are in a situa-
tion which requires full braking, it is
best to brake using maximum brake
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.
Do not drive with your foot resting
on the brake pedal. Otherwise,
even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.<
Wet roads:
if the roads are wet or if there is heavy
rain, it is advisable to gently press the
brakes for a brief moment every few
miles/kilometers. Monitor traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat generated in this process helps
dry the pads and rotors. Immediate
braking force is then available if neces-
sary.

126
Inclines:
To prevent overheating and, as a
result, diminished braking effec-
tiveness, drive down long or steep
downhill grades in a gear which
requires the least braking. Otherwise,
even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.<
The braking power of the engine can be
further enhanced by downshifting the
automatic transmission in manual
mode, if necessary, into first gear. This
helps avoid placing excessive loads on
the brake system.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in Neutral. Do not
coast with the engine switched off. Oth-
erwise, the engine provides no braking
effect while the transmission is in idling
position, and there is no power-assist
for braking or steering when the engine
is off.
Floor mats, floor carpets or other
objects must not be in the area near the
brake or accelerator pedal, as this
could impair the movement of the ped-
als.<
Corrosion on the brake rotorsLimited vehicle use, extended periods
with the vehicle parked or in storage,
and operating conditions in which brak-
ing is restricted to gentle, low-pressure
applications will all increase the ten-
dency for corrosion to form on the
rotors and contamination to accumulate
on the brake pads. This occurs because
the minimal pressure 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 that even extended
brake applications will fail to cure.
Brake pads
For your own safety: use only
brake pads that BMW has
released for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suitable for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Portable phone in the vehicle
BMW advises against using
mobile equipment, e.g. cellular
phones, inside the vehicle without con-
necting them directly to an outside
antenna. Otherwise, it cannot be ruled
out that vehicle electronics and the
mobile equipment interfere with one
another. In addition, it is not ensured
that the radio waves emitted during
transmission are directed outside of the
vehicle interior.<
General driving notes

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 91. 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. Press the trim piece 1 on each side
of the car upwards and remove. Do
so by pulling the tab on trim
piece 1 in the direction of travel

4. Open the two locking levers at the
front of the hardtop. Press on the
buttons to do so. The levers will
release slightly. Open the levers as
far as possible
5. Before installing, first flip down the
cover panels 2 that are located
underneath the left and right inte-
rior lamps. To do this, press on the
slight bump on cover panel 2.
There is a holder in the cover panel
to securely store the trim pieces
that have been removed. Pull the
adapter 3 out of the holder, clip the
trim piece into the bottom and rein-
sert the adapter
6. Open the red locking levers as far
as the stop will allow, see arrow 4
7. Position the hardtop onto the sup-
port brackets with the help of a
second person. Be sure to put the
mountings exactly into the proper
brackets
Lift the hardtop carefully. Be
extremely careful not to shift the
seals. Seals that have been shifted out
of place or actually pulled out cause
leaks.<
8. In the back, close the red locking
levers by turning to the inside as far
as the stop located behind the trim
will allow. Flip the cover panels
back into place
9. To lock the hardtop in the front,
close the front locking levers until
you hear them engage
10. Check the seal between the wind-
shield frame and the hardtop on
both the left and right sides. If it is
folded or bent out of place, you
should smooth it back into position
by hand to ensure secure and reli-
able sealing.RemovalFollow the same procedure as when
installing, just reverse the steps.

130Wheels and tires
Tire inflation pressureInformation for your safetyIt is not merely the tire's service life, but
also driving comfort and, above all else,
driving safety that depend on the condi-
tion of the tires and the maintenance of
the specified tire inflation pressure.
Check tire inflation pressures on a
regular basis and correct them, if
necessary, including the compact
wheel: at least twice a month and
before beginning a longer trip. If this is
not done, incorrect tire pressures can
cause driving instability and tire dam-
age, ultimately resulting in accidents.
Do not drive with a pressureless, i.e.
flat, tire, unless your vehicle is
equipped with Run Flat tires. A flat tire
greatly impairs steering and braking
response, and can lead to complete
loss of control over the vehicle. of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor,
refer to page 93.
Inflation pressures for original
tiresTire pressures for the standard tires of
your vehicle are shown on the driver's
door post, visible when the door is
open.
The inflation pressures apply to BMW-
approved tire sizes and recommended
tire brands. Your BMW center will be
glad to supply this information.Inflation pressures for other tire
sizesThe following tire pressure table shows
all tire pressures for the given tire sizes
at ambient temperature.
