Use of the engine

Breaking-in
Today's most modern methods of
production afford high precision in the
construction and coupling of
components. However, the moving
parts do undergo a settling process,
basically in the first hours of the
vehicle operation.

Engine and transmission

Avoid exceeding 5000 r.p.m. for the
first 1,000 trip km.
After starting the vehicle, do not
exceed 4,000 r.p.m. until the engine
5
has warmed up sufficiently (water
temperature: 65, 70 °C - 149,158 °F).
Do not drive keeping the engine at a
constant high speed rate for a
prolonged time.

Use of the engine

While driving

Never travel with the Rev. Counter
indicator approaching the peak r.p.m. -
not even downhill.
When the Rev. Counter indicator is
approaching the peak r.p.m. (red-
coloured zone), take precautions to
avoid exceeding that limit.
WARNING: Under normal conditions,
all the red light warning indicators on
the instrument panel's multi-function
display should be off. When they come
on, they indicate a malfunction in the
relative system. The only exception is
the engine oil level warning light, see
page 243.
Ensure proper operation of the various
devices by checking the respective
control instruments.
WARNING: Continuing to drive when a
red warning light switches on could
cause serious damage to the vehicle
and affect its performance.
Do not travel downhill with
the engine off, as the servo
brake will no longer function
due to the vacuum decrease and thus
after a few braking attempts, the
system becomes totally inefficient.
The power steering will also lose its
efficiency in these condition.
