marked items in this’ maintenance chart, note the following points.
Major service interval at 12 months!ZO,OOO km (I 2,000 miles).
Lubrication service based on distance only, 10,000 km (6,000 miles), not time.
Adjust or inspect alternator and water pump drive belt, and power steering and air conditioner drive belt
ii equipped.
Replacement of the timing belt is required every ICQOUO km (60,000 miles). Failure to replace the timing
belt may result in damage to the engine.
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 recommended intervals.
a) Driving in dusty conditions.
b) Extended periods of idling or low speed operation.
c) Driving for prolonged periods in cold temperatures or regularly driving only short distances.
If the vehicle is operated in very dusty or sandy areas, inspect and, if necessary, replace more often
than the recommended intervals.
This is a full function check of all electrical systems, i.e, afl lights, washers (inctuding condition of blades)
electric windows sunroof, horn, etc.
Replace every two years.
tf there has been continuous hard driving, mountain driving, or it 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.

OUTLINE Fl
OlJTLlNE OF CONSTRUCTION
The fuel and emission control systems of the New 3.23 BP SOHC-engine equipped 4WD model are basically
the same as those of the New 323 8P DOHC-engine equipped 2WD model, however, the fuel tank is designed
with separate right
and left sections due to the installation of the propeller shaft for the 4-wheel-drive system
and
a transfer pump is equipped to pump the fuel from the left to the right (fuei pump side) section of the
fue! tank. The following chart shows the differences between the major parts of the BP DO% 2WD model
and the BP SOHC 4WD model.

FUELSYSTEM
PRECAUTION
Fuel Pressure Release and Sewicing Fuel System
Fuel in the fuel system remains under high pressure when the
engine is not running.
a) Before disconnecting any fuel line, release the fuel
pres-
sure from the fuel system to reduce the possibility of injury
or fire.
1. Start the engine.
2. Push the rear seat cushion buttons and remove the
cushion.
3. Disconnect the fuel pump connector.
4. After the engine stalls, turn off the ignition switch.
5. Reconnect the fuel pump connector and install the rear
seat cushion.
b) Use a rag as protection from fuel spray when disconnect-
ing the hoses.
Plug the hoses after removal.
c> When inspecting the fuel system, use a suitable fuel pres-
sure gauge.
Caution
l Install hose clamps to secure tile fuel pressure
gauge to the fuel filter and the fuel main hose to pre-
vent fuel leakage.
Priming Fuel System
After releasing the fuel pressure for repairs or inspection, the
system must be primed to avoid excessive cranking when first
starting the engine. Follow the
steps below.
I. Connect the diagnosis connector terminals F/P and GND
with a jumper wire.
2. Turn the ignition switch ON for approx. IO sec. and check
for fuel leaks.
3. Turn the ignition switch OFF and remove the jumper wire.

TRANSFER PUMP CONTROL SYSTEM
2. Remove the service hole cover of the transfer pump.
3. Disconnect the transfer pump connectors.
4. Disconnect the fuel hose.
5. Remove the transfer pump.
Caution
l Install a new seal rubber.
6. Install in the reverse order of removal.
