En gine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAU17085
0–1000 km (0–600 mi)
Avoid prolonged operation above 7000
r/min. NOTICE: After 1000 km (600
mi) of operation, the en gine oil must
b e chan ged an d the oil filter car-
tri dg e or element replace d.
[ECA10303]

the tachometer red zone.
 If any en gine trou ble shoul d oc-
cur during the en gine break-in
period , imme diately have a

cle.TIPDuring and after the engine break-in
period, the exhaust heat may cause
discoloration of the exhaust pipe, but
this is normal.
