REMARKS
After 80,000 km or 48 months, continue to follow the described maintenance at the recommended intervals.
As for * marked items in this maintenance chart, note the following points.
* 1 Major service interval at 12 months120,OOO km (12,000 miles).
Lubrication service based on distance only 10,000 km (6,000 miles) not time.
*2 Adjust or inspect alternator and water pump drive belt, and power steering and air conditioner drive belt
if equipped.
“3 Replacement of the timing belt is required at every 100,000 km (60,000 mile). failure to replace the tim-
ing belt may result in damage to the engine.
“4 If the vehicle is operated under any of the following conditions, it is suggested that the engine oil and
oil filter be changed more often than the &commended intervals.
a) Driving in dusty conditions.
b) Extended periods of idling or low speed operation.
c> Driving for a prolonged periods in cold temperatures or regularly driving only short distances.
*5 If the vehicle is operated in very dusty or sandy areas, inspect and, if necessary, replace more oten
than at usual recommended intervals.
*6 This is a full function check of all electrical systems, i.e, all lights, washers (including condition of blades)
electric windows, sunroof, horn etc.
“7 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.
Emission Control and Related Systems
The ignition and fuel systems are vitally important to the proper operation of the emission control and related
system, as well as for efficient engine operation. It is strongly recommended that all servicing related to these
systems be done by your Authorised Mazda Dealer.
