Special operating instructions
Break-in procedures
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, please take note of the
following differences for your BMW Z4 M Road-
ster/Z4 M Coupe.
Always obey all official speed limits.
Engine and differential
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed 5,500 rpm or 105 mph/170 km/h.
Strictly avoid depressing the accelerator pedal
to full-throttle position.
After the breaking-in inspection at 1,200 miles/
2,000 km, engine or road speeds can be gradu-
ally increased.
Transmission
The function of the transmission reaches its
optimal level only after driving a distance of
approx. 300 miles/500 km. Do not exceed
engine speeds of 5,500 rpm during this time.
After replacing components
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Driving notes
Ground clearance
The front spoiler greatly restricts the
vehicle's ground clearance. Make sure
that your BMW always has sufficient ground
clearance, e.g. when entering underground
garage complexes or driving over the edge of a
curb; otherwise the front spoiler could be dam-
aged.

Braking safely
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, your BMW Z4 M Road-
ster/Z4 M Coupe is equipped with perforated
brake discs.
In certain braking situations, operation of the
perforated brake discs can cause noise; how-
ever, this does not affect the performance and
operating safety of the brakes.
