NOTE:
As the result of visual examination or functional measurement of a system's operation(performance), correct, clean or replace as required.
REMARKS:
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. If the vehicle is operated 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 regularly.
"2. 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.
*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 Adjust or inspect alternator and water pump drive belt, and power steering and air conditioner drive belt, vacuum pump belt, super charger belt if equipped.
*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.
*6. Only F6 carbretor for Singapore (MTX Model)
Emission Control and Related Systems
The ignition and fuel systems are vitally important to the proper operation of the emissions control and related systems, as well as for efficient engine operation. It i
strongly recommended that all servicing related to these systems be done by your Authorized Mazda Dealer.
