Special operating instructions
Break-in procedures
To 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.
Because of its engineering design, 
the BMW M3 Convertible is an 
especially high-quality vehicle. It is in 
your best interest to follow the break-in 
tips very closely. Doing this, you will 
create the basis for a long, optimum 
service life.
<
Engine and differential
> The first 1,250 miles/2,000 km: drive 
at varying engine and road speeds, 
but do not exceed the following 
engine or road speeds:
5,500 rpm or 105 mph / 170 km/h.
Always obey all official speed limits.
Do not depress the accelerator pedal to 
the full-throttle position.
Vehicles with SMG Drivelogic, refer to 
page 
gram 6 in the sequential mode during 
the break-in period.
> Following the break-in inspection at 
1,250 miles/2,000 km, you can grad-
ually increase engine or road speeds.
Please remember to observe the same 
break-in procedures if either the engine 
or the differential should have to be 
replaced later in the course of the vehi-
cle's service life.
Tires
Owing 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.
When the vehicle is operated on 
wet or slushy roads, a wedge of 
water may form between the tire and 
the road surface. This phenomenon is 
referred to as hydroplaning, and can 
lead to partial or complete loss of trac-
tion, vehicle control and braking effec-
tiveness. Reduce your speed on wet 
roads.
<
Brake system
Approx. 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 – at a traf-
fic signal, for instance; use caution to 
avoid posing a danger to other road 
users.
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.
