Break-in procedures
Moving parts need to be given some time until
they can interact smoothly with one another. To
ensure that your vehicle provides maximum
economy throughout a long service life, we
request that you observe the following:
Engine and differential
Up to 1,200 miles/2,000 km:
Drive at varying engine and road speeds, but do
not exceed the following engine or road speed:
4,500 rpm / 4,500/min or 100 mph / 160 km/h.
Obey your local and state maximum speed lim-
its.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kickdown point.
After you have driven 1,200 miles/2,000 km,
you can gradually increase the engine or road
speeds.
Sequential manual gearbox SMG
Up to 1,200 miles/2,000 km:
Do not use the acceleration assistant during the
break-in period.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until an initial break-in period has
elapsed. You should therefore drive with extra
caution during the first 200 miles/300 km.
Obey your local and state maximum speed lim-
its.
When the vehicle is operated on wet or
slushy roads, a wedge of water may form
between the tire and the road surface. This phe-
nomenon is referred to as hydroplaning and can
lead to partial or complete loss of traction, vehi-
cle control and braking effectiveness. Reduce
your speed on wet roads.<
Brake system
Approx. 300 miles/500 km must elapse before
the brake pads and rotors achieve their optimal
surface and wear pattern.
To break in the separate parking brake drums,
apply the parking brake lightly when coasting to
a standstill – at a traffic signal, for instance; use
caution to avoid posing a danger to other road
users.
To avoid corrosion, repeat this procedure from
time to time.
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 car with
the engine off, e.g. by towing, substantially
higher levels of pedal force will be required to
brake the vehicle.<
Clutch
The clutch will achieve its optimal functionality
after approx. 300 miles/500 km. Shift gears
carefully during the break-in period.
After replacing components
Follow the same break-in procedure again if any
of the components mentioned above have to be
replaced in the future.
Driving notes
Close the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is completely
closed, otherwise exhaust fumes could pene-
trate into the interior of the vehicle.<
Should it be absolutely necessary to operate
the vehicle with the luggage compartment lid
open and with the convertible top closed:

1.Close all windows
2.Increase the air supply from the air condi-
tioner or automatic climate control to a high
level. Refer to page58 or61.
Hot exhaust system
High temperatures occur with every vehi-
cle equipped with a catalytic converter.
Heat shields are installed adjacent to some sec-
tions of the exhaust system. Never remove
these shields; do not apply undercoating to
their surfaces. When driving, standing at idle
and parking the vehicle, take care to avoid con-
tact between the hot exhaust system and flam-
mable materials, e.g. hay, leaves, grass, etc.
Such contact could lead to a fire, resulting in
serious personal injury and property damage.<
Hydroplaning
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the tires and
the road surface. This phenomenon can lead to
partial or complete loss of traction, vehicle con-
trol and braking effectiveness.<
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. Otherwise, the vehicle's engine,
the electrical systems and the transmission
may be damaged.<
Use the parking brake on inclines
On inclines, keep the vehicle from rolling
by using the parking brake rather than by
slipping the clutch, which would lead to a high
degree of clutch wear.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. If you are in a situation which requires
full braking, it is best to brake using maximum
brake pressure: panic stop. Since the vehicle
maintains steering responsiveness, you can still
avoid possible obstacles with a minimum of
steering effort.Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver that ABS is in its active mode.
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. Watch
traffic conditions to ensure that this maneuver
does not endanger other road users. The
resulting heat dries the brake rotors and brake
pads. Immediate braking force is then available
if necessary.
Inclines
To prevent overheating and, as a result,
diminished braking effectiveness, drive
down long or steep downhill grades in a gear
which requires the least braking. Otherwise,
even light but consistent pedal pressure can
lead to high temperatures, brake wear and pos-
sibly even brake failure.<
The braking power of the engine can be further
enhanced by downshifting the automatic trans-
mission in manual mode, if necessary, into first
gear; refer to pages39 and41. This prevents an
excessive load on the brakes.
Do not coast with the clutch depressed or
with the transmission or selector lever in
Neutral. Do not coast with the engine switched
off. Otherwise, the engine provides no braking
effect while the transmission is in idling posi-
tion, 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
pedals.<
Corrosion on the brake rotors
Limited vehicle use, extended periods with the
vehicle parked or in storage, and operating con-
ditions in which braking is restricted to gentle,
low-pressure applications will all increase the
tendency for corrosion to form on the rotors and
contamination to accumulate on the brake
pads. This occurs because the minimal pres-
Page 72 of 120
Special operating instructions
70 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.
Interior and exterior mirrors with
automatic dimming feature*
Two photocells in the interior rearview mirror
serve to control the interior and exterior mirrors
with automatic dimming feature. One photocell
is positioned in the mirror's lens, see arrow,
while the other is on the opposite side of the
mirror.
To ensure perfect functioning, keep the photo-
cells clean and the area between the interior
rearview mirror and the windshield free of any
obstruction like stickers, etc.
When the vehicle is parked
Condensation formed in the air conditioning
system during operation exits under the vehi-
cle. Traces of condensed water on the ground
underneath the vehicle are thus normal.
Mobile equipment in the vehicle
BMW advises against using mobile
equipment, e.g. cellular phones, inside
the vehicle without connecting them directly to
an outside antenna. Otherwise, it cannot be
ruled out that vehicle electronics and the mobile
equipment interfere with one another. In addi-
tion, it is not ensured that the radio waves emit-
ted during transmission are directed outside of
the vehicle interior.<
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 damage to the
vehicle and unstable driving conditions
could result.<
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. pas-
sengers 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.
