DISASSEMBLY
1. Inspection of parts
Each part when removed should be carefully inspect-
ed for malfunctioning, deformation, damage, and
other problems.

All disassembled parts should be carefully arranged
for reassembly.
Be sure to separate or otherwise identify the parts to
be replaced from those that will be reused.
3. Cleaning parts for reuse
All parts to be reused should be carefully and
thoroughly cleaned in the appropriate method.
REASSEMBLY

ments, must be strictly observed in the reassembly
of all parts.
If removed, these parts should be replaced with new
ones:
1. Oil seals
2. Gasket
3. O-rings

REMARKS:
Major service interval at 12 months/20,000 km (12,000 Miles), Lubrication service based on distance only 10,000 km (6,000 Miles) not time
After 80,000 km (48,000 Miles) or 48 months, continue to follow the described maintenance items and intervals periodically.
As for * marked items in this maintenance chart, please pay attention to the following points.
*1 Replacement of the timing belt is required at every 100,000 km (60,000 Miles). Failure to repace the timing belt may result in damage to the engine.
*2 If the vehicle is operatie under the following conditions, it is suggested that the engine oil and oil filter be changed more often than at usual recommended intervals.
a) Driving in dusty conditions.
b) Extended periods of idling or low speed operation.
c) Driving for a prolonged period in cold temperatures or driving only short distances regulary.
*3. If the vehicle is operated in very dusty or sandy areas, inspect and, if necessary, replace more often than at usual recommended intervals.
*4. This is a full function check of all electrical systems, i.e., all lights, washers (including condition of blades) electrical windows, sunroof, horn, etc....
*5. Replace every two years.
If there has been continuous hard driving, mountain driving, or if the brakes are used extensively or the vehicle is operated in extremely humid climates, the
brake fluid should be changed annually.
