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.
EAU17094
0–1000 km (0–600 mi)
Avoid prolonged operation above 5600

TIPThis model is equipped with:
 a lean angle sensor. This sensor
stops the engine in case of a vehi-
cle turnover. If this happens, the
engine trouble warning light will
come on, but this is not a malfunc-
tion. Turn the vehicle power off
and then back on again to cancel
the warning light. Failing to do so
will prevent the engine from start-
ing even though the engine will
crank when pushing the start
switch.
 an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. If the engine
stops, simply push the start
switch to restart the engine.
