Using the engine
Running-in
Today’s most modern methods of
production afford high precision in
the construction and assembly of
components. However, the moving
parts do undergo a settling process,
during the first hours of vehicle
operation.
Engine and transmission
Avoid exceeding 5000 RPM for the
first 620 mi (1000 km).
After starting, do not exceed 4000
RPM until the engine has warmed up
sufficiently (water temperature: 149-
158 °F/65-70 °C).
Do not let the engine run at a
constantly high speed for a prolonged
time.
While driving
Never travel with the tachometer
approaching the peak RPM - not even
downhill.
When the tachometer is approaching
the peak RPM (red sector), take
precautions to avoid exceeding that
limit.
WARNING: Under normal conditions,
all the red light warning lights on
the instrument panel should be off.
When they illuminate, they indicate
a malfunction in the relative system.
The only exception is the engine oil
level warning light, see page 214.
Ensure proper operation of the
various devices by checking the
relevant control gauges.
WARNING: Continuing to drive when
a red warning light is on could cause
serious damage to the vehicle and
affect performance.
Never turn the engine off
while driving downhill as the
vacuum decrease prevents
the brake booster from functioning
correctly. After a few attempts at
braking the system will become
almost completely inefficient. The
power steering will also lose its
efficiency in these condition.
