GENERAL PRECAUTIONS
The WARNING and CAUTION below describe some general precautions that you should observe when servicing
a vehicle. These general precautions apply to many of the service procedures described in this manual, and they
will not necessarily be repeated with each procedure to which they apply.
WARNING:

Whenever raising a vehicle for service, be sure to follow the instructions under ªVEHICLE LIFTING
POINTSº on SECTION 0A.

When it is necessary to do service work with the engine running, make sure that the parking brake
is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for automatic
transmission vehicles). Keep hands, hair, clothing, tools, etc. away from the fan and belts when the
engine is running.

When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.

Do not perform service work in areas where combustible materials can come in contact with a hot
exhaust system. When working with toxic or flammable materials (such as gasoline and refrigerant),
make sure that the area you work in is well-ventilated.

To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold, tail-
pipe, muffler, etc.

New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new or
used oil. Keep new and used oil and used engine oil filters away from children and pets.
Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory animals.
Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil, wear a
long-sleeve shirt and moisture-proof gloves (such as dishwashing gloves) when changing engine oil.
If engine oil contacts your skin, wash thoroughly with soap and water. Launder any clothing or rags
if wet with oil, recycle or properly dispose of used oil and filters.

Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpectedly
during driving, obstructing your view and resulting in an accident.
CAUTION:

Before starting any service work, cover fenders, seats and
any other parts that are likely to get scratched or stained dur-
ing servicing. Also, be aware that what you wear (e.g, but-
tons) may cause damage to the vehicle's finish.

When performing service to electrical parts that does not re-
quire use of battery power, disconnect the negative cable of
the battery.

GENERAL INFORMATION 0A-9

When disconnecting vacuum hoses, attach a tag describing
the correct installation positions so that the hoses can be re-
installed correctly.

After servicing fuel, oil, coolant, vacuum, exhaust or brake
systems, check all lines related to the system for leaks.

For vehicles equipped with fuel injection systems, never dis-
connect the fuel line between the fuel pump and injector
without first releasing the fuel pressure, or fuel can be
sprayed out under pressure.
PRECAUTIONS FOR CATALYTIC CONVERTER
For vehicles equipped with a catalytic converter, use only un-
leaded gasoline and be careful not to let a large amount of un-
burned gasoline enter the converter or it can be damaged.
± Conduct a spark jump test only when necessary, make it as
short as possible, and do not open the throttle.
± Conduct engine compression checks within the shortest
possible time.
± Avoid situations which can result in engine misfire (e.g.
starting the engine when the fuel tank is nearly empty).

GENERAL INFORMATION 0A-19
VEHICLE LIFTING POINTS
WARNING

When using frame contact hoist, apply hoist as shown (right and left at the same position). Lift up the
vehicle till 4 tires are a little off the ground and make sure that the vehicle will not fall off by trying to
move vehicle body in both ways. Work can be started only after this confirmation.

Before applying hoist to underbody, always take vehicle balance throughout service into consider-
ation. Vehicle balance on hoist may change depending of what part to be removed.

Make absolutely sure to lock hoist after vehicle is hoisted up.

Before lifting up the vehicle, check to be sure that end of hoist arm is not in contact with brake pipe,
fuel pipe, bracket or any other part.

Pedal inspection
Check clutch pedal for height and free travel referring to Section
7C1. Adjust or correct if necessary.
Fluid inspection
1) Check around master cylinder and reservoir for fluid leakage.
If found leaky, correct.
2) Check fluid level.
If fluid level is lower than the minimum level of reservoir, refilling
is necessary. Fill reservoir with specified brake fluid indicated on
clutch reservoir cap.
For the details, refer to On-vehicle service in Section 7C1.
CAUTION:
Since clutch system of this vehicle is factory-filled with
glycol-base brake fluid, do not use or mix different type
of fluid when refilling system; otherwise serious damage
will occur. Do not use old or used brake fluid, or one taken
from unsealed container.
ITEM 6-2
Brake Discs, Pads, Brake Drums and Shoes Inspection
[Brake discs and pads]
1) Remove wheel and caliper but don't disconnect brake hose from
caliper.
2) Check front disc brake pads and discs for excessive wear, dam-
age and deflection. Replace parts as necessary. For details, re-
fer to Section 5B.
Be sure to torque caliper pin bolts to specification.
[Brake drums and shoes]
1) Remove wheel and brake drum.
2) Check rear brake drums and brake linings for excessive wear
and damage, while wheels and drums are removed. At the same
time, check wheel cylinders for leaks. Replace these parts as
necessary.
For details, refer to Section 5C.

Parking Brake Lever and Cable Inspection
Parking brake lever
1) Check tooth tip of each notch for damage or wear. If any damage
or wear is found, replace parking lever.
2) Check parking brake lever for proper operation and stroke, and
adjust it if necessary.
For checking and adjusting procedures, refer to Parking Brake
Inspection and Adjustment in Section 5.

FINAL INSPECTION
Seats
Check that seat slides smoothly and locks securely at
any position. Also check that reclining mechanism of
front seat back allows it to be locked at any angle.
Seat Belt
Inspect belt system including webbing, buckles, latch
plates, retractors and anchors for damage or wear.
If ªREPLACE BELTº label on front seat belt is visible,
replace belt.
Check that seat belt is securely locked.
Battery Electrolyte Level Check
Check that the electrolyte level of all battery cells is
between the upper and lower level lines on the case.
If battery is equipped with built-in indicator, check bat-
tery condition by the indicator.
Accelerator Pedal Operation
Check that pedal operates smoothly without getting
caught or interfered by and other part.
Engine Start
Check engine start for readiness.
On automatic transmission vehicles, try to start the
engine in each select lever position. The starting mo-
tor should crank only in ªPº (Park) or ªNº (Neutral).
On manual transmission vehicles, place the shift le-
ver in ªNeutral,º depress clutch pedal fully and try to
start.
Exhaust System Check
Check for leakage, cracks or loose supports.
Clutch (For Manual transmission)
Check for the following:

Clutch is completely released when depressing
clutch pedal.

No slipping clutch occurs when releasing pedal and
accelerating.

Clutch itself is free from any abnormal condition.
Gearshift or Select Lever (Transmission)
Check gear shift or select lever for smooth shifting to
all positions and for good performance of transmis-
sion in any position.
With automatic transmission equipped vehicle, also
check that shift indicator indicates properly according
to which position select lever is shifted to.
With automatic transmission equipped vehicle, make
sure that vehicle is at complete stop when shifting se-
lect lever to ªPº range position and release all brakes.
Brake
[Foot brake]
Check the following:

that brake pedal has proper travel,

that brake works properly,

that it is free from noise,

that braking force is applied equally on all wheels,

and that brake do not drag.
[Parking brake]
Check that lever has proper travel.
WARNING:
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property damage.
Be prepared to apply regular brake quickly
even if vehicle should start to move.
Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and
brake lever is pulled all the way.
WARNING:
When carrying out road tests, select a safe
place where no man or no running vehicle is
seen so as to prevent any accident.
WARNING:
Before performing the following check, be
sure to have enough room around the vehicle.
Then, firmly apply both the parking brake and
the regular brakes. Do not use the accelerator
pedal. If the engine starts, be ready to turn off
the ignition promptly. Take these precautions
because the vehicle could move without warn-
ing and possibly cause personal injury or
property damage.
