<HANDLING FOR POOR STARTING>
During cold season or when frequent
short-distance traveling, the starting may
be poor and even the engine will be OFF.
This may be prevented by use of spark
plug. The spark plug of this vehicle is
equipped as standard when delivery.
However, the starting will be poor if the
vehicle is continuously driven under low
speed.
CAUTION
If plug of different maker or different
heat value is used, it causes
unsatisfactory engine starting,
inadequate engine revolution and
output deterioration.
After driving, the spark plug become
very hot. When inspecting, pay
attention not to be burned.
