Things to remember when driving

Break-in period

Moving parts need breaking-in time to adjust to

each other. Please follow the instructions below

in order to achieve the optimal service life and

economy of operation for your vehicle.

Engine and differential

Always obey all official speed limits.

Up to 1,200 miles/2,000 km

Drive at varying engine and road speeds, but do

not exceed an engine speed of 5,500 rpm or a

road speed of 105 mph/170 km/h.

Do not depress the accelerator all the way.

From 1,200 miles/2,000 km to

3,000 miles/5,000 km

Engine and road speeds can be increased grad-

ually up to a traveling speed of 135 mph/

220 km/h. Use the maximum speed only for

brief intervals, e.g. when passing.

Transmission

The transmission begins functioning at an opti-

mal level only after a distance of approx.

300 miles/500 km. Do not exceed engine

speeds of 5,500 rpm during this period.

Tires

Due to technical factors associated with their

manufacture, tires do not achieve their full trac-

tion potential until after an initial break-in

period. Therefore, drive cautiously during the

first 200 miles/300 km.

Brake system

Brakes require an initial break-in period of

approx. 300 miles/500 km to achieve optimized

contact and wear patterns between brake pads

and rotors. Drive cautiously during this break-in

period.

Clutch

The function of the clutch reaches its optimal

level only after a distance driven of approx.

300 miles/500 km. During this break-in period,

engage the clutch gently.

Following part replacement

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.

BMW M3 engineering

High performance V8 engine

The high-revving V8 engine draws a maximum

power of 420 hp/309 kW and a peak torque of

295 lb ft/400 Nm from a displacement of

244 cu in/4 l. Its spontaneous response results

in a very wide effective rpm range. The maxi-

mum engine speed lies at 8,400 rpm and is

electronically controlled. Due to the high engine

dynamics, the maximum engine speed is lim-

ited to 7,000 rpm when the vehicle is standing.

Warming up the engine

During the warm-up phase, the high-perfor-

mance V8 engine runs a little more roughly due

to its emissions control system.

For technical reasons, the exhaust system

sounds slightly metallic when the engine is

cold.
