Running-in notes
Important safety notes
New or replaced brake pads/linings and
discs only reach their optimum braking effect
after several hundred kilometres of driving.
Compensate for the reduced braking effect
by applying greater force to the brake pedal.
The first 1,500 km
If you treat the engine with sufficient care
from the very start, you will be rewarded with
excellent performance for the remainder of
the engine's life.
R Drive at varying vehicle speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gear in good time, before the rev
counter needle is Ô of the way to the red
area of the rev counter.
R Do not shift down a gear manually in order
to brake.
Vehicles with automatic transmission:
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.
i You should also observe these notes on
running-in if the engine or parts of the drive
train on your vehicle have been replaced.
