THE
FIRST
1500 KM - AND AFTERWARDS
During the
first
few operating hours the
engine internal friction is higher than
later on when all the moving parts have
bedded
down. How well this running in
process
is done depends to a consider-
able
extent on the way the vehicle is
driven during the
first
1500 km.
Up to 1000 km
do not use
full
throttle
at all.
Furthermore the following speeds in
km/h should not be exceeded in the
gears:

The
maximum
permissible engine speed
during the
first
1000 km is 4000 rpm.
The
speeds given here must however
not be exceeded.
From
1000-1500
km
the speed can gradually be increased to
the road or engine maximum.
After
the
running-in
period
on vehicles
with
a rev counter one
should
change
into
the next higher gear
at the latest by the time the red warning
zone
is reached.
The
maximum permissible engine
speeds
for continuous operation are:
Petrol
engines about 5400 rpm
Diesel
engines about 4600 rpm
Turbo Diesel engines . . about 4800 rpm
In isolated
cases,
for example when
overtaking the needle may move briefly
into
the dotted or shaded zone on the
rev counter scale - see also page 37.
A
speed limiter prevents extremely high
engine speeds.
Important
notes
• Do not overrev the engine when cold
- either in neutral or in the gears. All
speeds
and revs are only valid when
engine is properly warm.
• Do not drive
with
the engine speed
unnecessarily
high - changing up early
helps
to save fuel and reduces noise.
• Do not let engine labour - change
down when engine no longer runs
smoothly.
• New tyres must also be "run in" be-
cause
they do not have maximum adhe-
sion
at the start. This must be taken
into
account
by driving carefully during the
first
100 km.
