Special operating instructions
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:

Load
The permissible load is the sum of the occu-
pants' weights and the weight of the cargo. The
greater the weight of the occupants, the less
cargo can be transported.
Stowing cargo
>Load heavy cargo as far forward as possi-
ble, directly behind the luggage compart-
ment partition, and as low as possible
>Cover sharp edges and corners.
To avoid damaging the rear of the back-
rest or the rear interior trim panel, do not
stow heavy cargo or cargo with sharp edges
and corners behind the seats.
In addition, large and bulky cargo stowed
behind the seats may prevent the backrest from
engaging properly. Therefore, ensure that the
backrest is securely locked and if necessary,
move the seat forward, refer to page28.
Always position and secure the load as
described above; otherwise, it can endanger
the passengers, for example during braking or
evasive maneuvers.
Do not exceed the approved gross vehicle
weight or the specified maximum axle loads.
Refer to page103. Otherwise the vehicle's
operating safety is no longer assured and you are in violation of the law.
Do not stow heavy or hard objects in the pas-
senger compartment without first securing
them. Otherwise they would be thrown around
during braking and evasive maneuvers and
would endanger the occupants.<
Convertible top compartment
With the convertible top closed, you can
enlarge the luggage compartment, refer
to page19.
It is advisable to always fold down the covertible
top compartment panel as soon as you have
removed your cargo from the luggage compart-
ment. This way, you can be sure that you can
always operate the convertible top at any time.
Conversely, when the convertible top is closed,
raise the convertible top compartment panel
before stowing your cargo in the luggage com-
partment to avoid any damage to the convert-
ible top compartment or your load.
Do not stow any items on the convertible top
compartment panel since the convertible top
could be damaged while it is opening.<
If you stow cargo behind the seats of your
BMW:
>Only stow light objects such as clothing,
etc.
>Do not pile objects higher than the top edge
of the backrests.
