GI tMPORTANT INFORMATION
IMPORTANT INFORMATION
BASIC ASSUMPTIONS
This workshop manual assumes that you have certarn special tools that are necessary for the safe and
efficient performance of service operations on Mazda vehicles and that you know how to use them properly.
It also assumes that you are familiar with automobile systems and basic service and repair procedures.
YOU should not attempt to use this manual unless these assumpttons are correct and you understand the
consequences described below.
SAFETY RtSK
This manual contains certain notes, warnings, and other precautionary information that you should care-
fully read and follow to reduce the risk of personal injury to yourself or others and the risk of improper
service that may damage the vehicle or render it unsafe. If there IS no such information in regard to any
specific service method, this does not mean there is no possibility that personal safety or vehicle safety
wili be jeopardized by the use of incorrect methods or tools.
POSStBLE LOSS OF WARRANTY
The manufacturer’s warranty on Mazda vehicles and engines can be voided if improper service or repairs
are performed by persons other than those at an Authorked Mazda Dealer.
WARNtNG ON LUBRtCANTS AND GREASES
Avoid all prolonged and repeated contact with mineral oils, especially used oils. Used oils contaminated
during service (e+g., engine sump oils) are more irritating and more likely to cause serious effects, includ-
ing skin cancer, in the event of gross and prolonged skin contact.
Wash skin thoroughly after work involving 011.
Protective hand cleaners may be of value provided they can be removed from the skin with water Do
not use gasoline, paraffin, or other solvents to remove oil from the skrn.
Lubricants and greases may be slightly irritating to the eyes.
Repeated or protonged skin contact shoutd be avoided by wearing protective clothing if necessary. Par-
ticular care should be taken with used oils and greases containing lead. Do not allow work clothing .to
be contaminated with oil. Dry clean or launder such clothing at regular intervals.

FUNDAMENTAL PROCEDURES GI
A WORD ABOUT SAFETY
The following precautions must be followed when jacking up
the vehicle.
t . Block the wheels.
2. Use only the specfred jacking positions.
3. Support the vehicle with safety stands.
Start the engine only after making certain the engine compart-
ment is clear of tools and people. j
9MUGtX-003 PREPARATION OF TOOLS AND MEASURING
EQUIPMENT
8e sure that al! necessary toois and measuring equipment
are available before starting any work.
SPECIAL TOOLS
Use special tools when they are required.
47UOGX-Cm I 1 REMOVAL OF PARTS
While correcting a problem, try also to determine its cause
Begin work only after first learning which parts and subas-
semblies must be removed and disassembled for replace-
ment or repair. >
DISASSEMBLY
If the disassembly procedure is complex, requiring many
parts to be disassembled, all parts should be disassembled
in a.way that wiii not affect their performance or external
appearance and identified so that reassembly can be per-
formed easily and efficiently. I J

SPEEDOMETER TESTER CHECK
Caution
l Do not clutch abruptly.
l Do not attempt rabbit starts or accelerate quickly. 13EGIX-302
[Front wheel free-roller method]
1. Set the free roller securely on the floor under the front wheels
by matching it to the wheel base and front tread.
2. Place the vehicle softly on the tester and free roller.
3. Start the engine, and engage the clutch softly at a low speed
in 2nd gear; then gradually increase the speed.
4. Upon completion of the test, stop the engine by gradually
decelerating with soft braking.
[Front wheel jack-up method1
1’. Place the rear wheels on the roller.
2. Jack up the front wheels and mount on a safety stand.
3. Start the engine, and engage the clutch softly at a low speed
in 2nd gear; then gradually increase the speed.
Caution
l When using either the front wheel free-roller meth-
od or front wheel jack-up method, secure the vehi-
cle to prevent forward and lateral movement by
attaching towing hardware (chain or wire) to the
front and rear tow hook or tie-down hook.
BRAKE TESTER CHECK
Caution
. To stabilize the drag force of the viscous coupling,
conduct the brake test after the speedometer test.
1. Place the wheels to be tested (front or rear) on the roller.
2. Shift itit0 NEUTRAL.
3. Drive the tester roller and check.

1. Remove the propeller shaft.
2. Lock the center differential (2WD).
3. Place the front wheets on the roller.
4. Lock the rear wheels and apply the parking brake.
5. Drive the tester roller and check.
6. Upon completion of the test, gradually decelerate with soft
braking and stop the engine.
7. When the test is done, return the differential lclck rod to the
free condition (4WD) and reinstall the propeller shaft.
WHEEL BALANCER (On-the-car Balance)
1.
Jack up all four wheels. Support the wheels to be checked
(front or rear) with the wheel balancer sensor stand and the
remainrng wheels with safety stands.
2. Set the on-the-car balancer. With the center differential in
free condition, drove the tires with the engine; then check.

GI CAUTKN
PRECAUTIONS TO TAKE WHEN SERVICING AN ELECTRICAL SYSTEM l Note the following items when servicing the electrical system.
l Do not alter the wiring or electrical equipment in any way; this may damage the vehicle or cause a fire
from short-circuiting a circuit or overloading it.
l The negatrve (-) battery cable must be removed first and
rnstalled last. l Do not reptace with fuses exceedrng specified capacity
Cautron
l 8e sure that the ignitton and other switches are off
before disconnectrng or connecting the battery cables.
Failure to do so may damage the semrconductor
components. Caution l Repfacing a fuse with one of a larger capacrty than
desrgnated may damage components or cause a frre.
l Secure harnesses with provrded clamps to take up slack. l Tape areas of the harness
that may rub or bump l When mounting
components, be sure the
against sharp edges to
protect rt from damage. harness IS not caught or
damaged.
Caution
l Clamp all harnesses near vibratrng components (for
example, the engine) to remove slack and to prevent
contact resultrng from vibration. i Drsconnect heatsensitive l Make sure that the
parts (for example, relays
and ECU) when performing connectors are securely
connected when installed.
l Do not handle electrical components roughly or drop
them. maintenance (such as
weldrng) where
temperatures may exceed
80°C [176OFj.

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 months/20,000 km (12,000 miles).
Lubrication service based on distance only 10,000 km (6,000 miles) not time.
l 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 bett may result in damage to the engine.
‘4 tf 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. I
:
b) Extended periods of idling or low speed operation. i
i!
c) Driving for a prolonged periods in cold temperatures or regularly driving onty short distances.
*5 If the vehicle is operated in very dusty or sandy areas, inspect and, if necessary, replace more often
than at usual recommended intervals.
l 6 This IS a full function check of all electrical systems, i.e, atl
ltghts. washers (including condition of blades)
electric windows, sunroof, horn etc.
‘7 Replace every two years. $1
‘I
If there has been continuous hard driving, mountain
drivtng, 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 relat-
ed 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.
