Special operating instructions

Break-in procedures

To ensure that your vehicle provides

maximum economy throughout a long

service life, we request that you comply

with the following information.

Engine and differential

The first 1,250 miles/2,000 km:

Constantly vary both vehicle and engine

speeds, remembering not to exceed

4,500 rpm or vehicle speeds of over

100 mph / 160 km/h:

Always obey all official speed limits.

Do not use full throttle, and avoid

pressing the accelerator beyond the

kickdown point during these initial

miles.

You can then proceed to increase

engine or vehicle speeds once the ini-

tial 1,250 miles/2,000 km have elapsed.

Please remember to observe these

same break-in procedures if either the

engine or the differential should have to

be replaced later in the course of the

vehicle's service life.

Tires

Due to technical factors associated

with their manufacture, tires do not

achieve their full traction potential until

after an initial break-in period. 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 – provided that

traffic conditions allow you to do so.

To avoid corrosion, repeat this proce-

dure 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

vehicle with the engine off – when tow-

ing, for example – substantially higher

levels of pedal force will be required to

brake the vehicle.<

Clutch

Approx. 300 miles/500 km must elapse

before the clutch starts to operate at

optimum efficiency. Remember to

engage the clutch carefully during this

initial period.
